DIY air ionizer repair

In detail: DIY repair of air ionizers from a real master for the site my.housecope.com.

About the details: C1 - a film capacitor for 2 microfarads with a voltage of 250 to 400 volts, diodes can be replaced with any imported ones with a voltage of at least 400 volts and a current of at least 3 amperes. The P2 regulator must be selected with a power of at least 2 watts. The thyristor must be supplied with a heat sink because it will heat up. In general, the entire structure of the ionizer was assembled several times and only one drawback of this circuit was noticed - almost all parts, except for capacitors, were heated and sometimes even very strongly. It is advisable to install the cooler of the ionizer so that it cools the entire system.

Now the most important part of the ionizer is the high voltage coil. We will wind it ourselves. For the coil, we take a ferrite rod from the radio receiver, 7 cm long and carefully insulate the rod with insulating tape. Next, we wind the primary winding with a 0.7 mm wire. It contains 30-50 turns. Then you need to insulate the primary winding with 5 layers of insulating tape and wind the secondary. It should be remembered that the primary and secondary windings wind in the same direction, otherwise the transformer will not work. The secondary winding has 100 turns of 0.1 millimeter wire and every 100 turns you need to insulate the windings with insulating tape or capacitor paper. After the end of winding, the finished transformer should be filled with epoxy resin.

We use the motor from a gramophone or a mixer, since they are quite small in size and operate on a 220 volt supply. I strongly advise you to use a motor from a gramophone! It works silently, and if you install the ionizer on a farm, you can use a motor from a mixer or a 220-volt hair dryer. You can also use electric motors with reduced voltage, but in this case, you also need to connect a step-down transformer.

For comparison, I will say that in order to ionize 3 liters of air, the ionizer needs to work for about 20 minutes. But still, how to practically use the work of the ionizer? It's very simple - we take a jar for storing fruits (there you need to put washed fruits, vegetables, and so on in advance). A special nozzle is pulled over the hose into which the neck of the can perfectly enters and exits. We insert the can, turn on the device, wait twenty minutes, then quickly take out the can and roll it up with a seaming or a sealed lid for canning. After that, you need to store the jars> and preferably not move! It is guaranteed that fruits can be stored in this way for 5-6 months. Thank you for your attention, the author is AKA.

Fresh air is essential for the well-being and general health of people. Air quality is highly dependent on the amount of positive and negative ions in the airspace. Of particular importance are negative ions that enter the body and form useful biologically active components in it. In the city, there are many negative factors that reduce the level of these gas particles. This problem is solved by an air ionizer that can be made by hand at home.

Studies have shown that the amount of ionized content in the airspace of city apartments, useful for humans, is about 10-15 times less than the required norm. In natural conditions, depending on the specific area, their number is 600-50,000 units per 1 cm 3.

A standard home air purifier increases the level of beneficial ions that have a beneficial effect on the body.Immunity is strengthened, sleep and the work of the cardiovascular system are normalized, a person is much less tired, and the risk of infectious and other diseases is reduced. The work of an ionizer for an apartment helps to remove allergens and dust, bacteria and viruses from the air, and the air itself becomes much cleaner.

The main function of the ionizer is to impart a negative charge to air particles, after which they become so-called air ions that have a beneficial effect on people. Due to the electrified oxygen molecules, the air environment is healed, and the general well-being of a person improves. In order for ordinary particles to become negative ions, the air mass must pass through a corona electric discharge. Allergens, dust, pathogens pass through the ionizer and receive an electrical charge.

After that, some part of them falls on the plate with the opposite charge and is attracted to it. Other harmful substances and particles quickly settle on surfaces near the ionizer, and then are removed during wet cleaning.

The creation of a corona discharge inside the ionizer is carried out under the influence of a high voltage electric current of at least 15 kV. Its supply is carried out from a step-up transformer in the form of pulses to pointed metal electrodes, which form a single system. At the same time, the formation of O3 molecules - ozone, harmful to the body in an amount exceeding the norm, occurs. Therefore, a hand-made air ionizer must provide the desired concentration by adjusting the discharge to a specific frequency and strength.

It should be borne in mind that it is not recommended to ionize the air using these devices in rooms where there are people with malignant tumors, with high temperatures, as well as children under 1 year of age. A self-made ionizer is undesirable for use in dusty or smoky rooms.

A homemade air purifier must be assembled in accordance with the diagram, following all the recommendations and procedures. An improperly assembled device can significantly harm health, cause injury in the form of burns or electric shock. In any case, before making an air ionizer with your own hands, you should prepare the necessary materials and parts.

A home-made device can be based on a case from a power supply from an old computer. A cooler from the same computer is suitable as a fan. You can take any power step-up transformer within 220 / 18-20 V, for example, TVS 90P4. From the materials it is necessary to prepare a textolite board, 2.5-3.0 mm thick, fasteners and connecting wires.

All radio parts are purchased in accordance with the diagram below:

KT315 transistors or similar elements with the same power are best suited. Zener diodes of the D815 circuit can also be replaced with similar ones. As a Zener diode VD4, elements KS512A or D815D are suitable.

Ready-made diode bridges can be replaced with separate diodes assembled into a single set. Their calculated voltage is 400 volts, and the current is not less than 0.5 A. Other parts of the circuit are replaced by analogs with the same technical characteristics.

The finished air purifier that this diagram represents will work in the following algorithm:

The generation of initial pulses is carried out using a multivibrator, assembled on the basis of low-power transistors VT1 and VT2 of the KT315 brand.
The frequency of such pulses is adjusted using a resistor R7 in the range from 30 to 60 kHz.
Further, the circuit assumes amplification of the generated pulses by transistors VT3 and VT4 of the KT816 brand, after which they are fed to the step-up transformer T2 to windings I and II.
The voltage is removed from the third winding within 2.5 kV, which, passing through the multiplier, rises to 15 kV, after which it goes to the working electrodes of this homemade product.

Copper stranded wire is used for the manufacture of ionizing electrodes. First, it is cleaned of insulation, and then all the veins are bent in different directions at 90 degrees in the form of an umbrella. It is installed from the body at a distance selected empirically so that the required amount of ions is generated.

The presented circuit of the air ionizer, in addition to the main elements, contains an SG1 spark gap, which is triggered at an increased voltage in the transformer winding. Of great importance is the blowing of air through the electrodes of the stranded wire - the umbrella. For this purpose, a cooler is mounted inside the power supply case. A power transformer and a stabilized rectifier unit are used to power it.

If a homemade air ionizer is made according to all the rules, it should work almost immediately. After that, all that remains is to make the necessary adjustments.

The car interior is a closed space with no fresh air flow. Relatively clean air can be obtained only with the help of an air conditioner, but there is no question of any quality. Therefore, many car enthusiasts purchase or make their own air purifier.

The manufacture of the device begins with a transformer. To do this, you need a core that can be removed from old devices and wires. Then the winding is wound: the primary consists of 14 turns, the secondary - of 600. After winding the primary winding, it must be insulated, for example, with 2-3 layers of tape. The secondary winding is also insulated every 100 turns.

For a voltage multiplier, you can use KTs106 diodes and 10 kW capacitors with a capacity of 3300 pF. The distance between the multiplier electrodes is 3 cm. After that, the finished air purifier is connected to the vehicle electrical system.

One of the most effective options for cleaning indoor air is the Chizhevsky chandelier. It includes two parts - the chandelier itself and the high voltage converter. Structurally, the device consists of an aluminum hoop, up to 1 meter in diameter, on which tinned copper wires with a diameter of 1 mm are fixed. The mesh spacing is 35-45 mm on average. The mesh itself sags about 6-9 cm relative to the hoop.A metal needle up to 4 cm long is soldered at each intersection point.

It is recommended to sharpen the needles as much as possible, from this the design will work much more efficiently. Three copper wires are attached to the hoop, spaced evenly every 120 degrees. Their ends are connected together over the hoop using soldering. Further, this point is connected to the high-voltage generator.

For normal operation, the Chizhevsky chandelier must be provided with a high-voltage voltage of at least 25 kV. This indicator may vary depending on the area of the room. For this purpose, the purifier circuit is supplemented with the required number of stages of the multiplier, which is a high-voltage generator.

If a homemade air ionizer is made according to all the rules, it should work almost immediately. After that, all that remains is to make the necessary adjustments.

Continuing the theme of the self-made Chizhevsky Chandelier, we offer another version of the converter. The design was published by S. BIRYUKOV, Moscow. Magazine "Radio", No. 2, 1997. As you know, the air ionizer consists of a high-voltage source of constant voltage of negative polarity and the actual "chandelier" - the "emitter" of air ions. Consider the high voltage source of the ionizer, the diagram of which is shown in the figure below.

The source works like this. The positive half-wave of the mains voltage through the diodes VD2, VD3 and resistors R5, R6 charges the capacitors C1 and C2. Transistor VT1 is open and saturated, and VT2 is closed.When the positive half-wave ends, the transistor VT1 closes, and VT2 opens. Capacitor C1 is discharged through the resistor R4 and the control junction of the SCR VS1. The SCR turns on, and the capacitor C2 is discharged to the primary winding of the transformer T1. In the oscillatory circuit, consisting of a capacitor C2 and a transformer winding, damped oscillations occur.

High voltage pulses arising on the secondary winding are fed to a multiplier made on diode poles VD6-VD11 and capacitors СЗ-С8. A negative voltage of about 30 kV from the output of the multiplier is fed through the current-limiting resistors R7-R9 to the “chandelier”. The source used mainly resistors MLT, R7-R9 - C2-29 (MLT with the same total resistance are also suitable), R6 - SPOE-1 or any other power of at least 1 W. Capacitors - K42U-2 for a voltage of 630 V (C1) and 160 V (C2) and KVI-3 for a voltage of 10 kV (SZ-S8). In place of C1 and C2, you can use capacitors for voltages of at least 400 and 160 V, respectively. Capacitors SZ-S8 - any other capacitors for a voltage of at least 10 kV and a capacity of at least 300 pF.

Diode VD1 - any low-power silicon, VD2 and VD3, VD4 - any for an operating voltage of at least 400 V. Diode VD5 - any of the KD202 series for a voltage of at least 200 V or other similar. High-voltage poles can be KTs110A, KTs105D, KTs117A, KTs118V or others for a voltage of at least 10 kV. Trinistor - series KU201 or KU202 for a voltage of at least 200 V. Transistor VT1 can be replaced by almost any n-p-n structure of low or medium power, for example, series KT312, KT315, KT3102, KT603, KT608; VT2 - any of the same structure of medium or high power with an acceptable collector-emitter voltage of at least 300 V, for example, KT850B, KT854A, KT940A. The B-115 automotive ignition coil is used as the T1 transformer, but any other automotive or motorcycle coil will do.

The MGShV-0.75 wire to the “chandelier” is brought out of the case through an insulator, machined from fluoroplastic, but you can use any thick-walled tube made of insulating material. In contrast, it is advisable to make a "chandelier" in the following order. First, you need to prepare the appropriate number of pins with a ring as needles.

Next, you need to make a ring with a diameter of 80 cm, bending it from a metal tube with a diameter of 5. 20 mm and connecting the ends of the tube end-to-end using a piece of a metal rod of a suitable diameter and rivets. Cut a circle out of corrugated cardboard that runs freely into the ring. Mark the circle with a grid with a side of squares 40 mm and stick the needles into the mesh nodes, then pull the tinned copper wire through the rings of the needles in two directions and solder the rings. Insert the circle into the ring and wind the ends of the wire around it, it is advisable to solder the turns. Carefully remove the cardboard circle, stretch the mesh a little to obtain the desired deflection - the "chandelier" is ready.

Install the "chandelier" at a distance of at least 80 cm from the ceiling, walls, lighting fixtures and 120 cm from where people are in the room. It is advisable to place it above the bed, fixing it on two lines with a diameter of 1 mm that are tightly stretched between the walls of the room. It is convenient to stretch the fishing line with a triangle - two hooks for fastening it are installed on the wall to which the "chandelier" is closer, one on the opposite wall. The "chandelier" itself is attached to the fishing line with small wire hooks.

In this version, I did not make a chandelier - I limited myself to such a compact design of the ion emitter. Before turning on the device for the first time, the variable resistor R6 should be set to the lower position according to the diagram. Having turned on the source with the “chandelier” connected to it, the voltage supplied to it is gradually increased by turning the axis of the resistor R6. After the appearance of the ozone smell, the stress is reduced until it disappears. If corona is observed in the high voltage source, locate it in the dark and cover it with molten paraffin (of course, when the source is de-energized). The ionizer collected and tested Fez.

Many of us pay mainly attention to what we eat, drink, what our daily routine is, and not what we breathe. Everyone knows that the air in cities is not very clean. Electronics will help here too. Namely, an air ionizer. The electrical circuit diagram is shown here.

Air outside the city (in meadows, in forests, near waterfalls and mountain rivers) contains 700 ... 3000, and sometimes up to 15,000 negatively charged ions in 1 cm 3 of air. There are areas where there are always more negatively charged ions in the air than positive ones. The more negative ions in the air, the more beneficial it is for health. In city apartments, the number of negative ions decreases to 25 per 1 cm 3. Therefore, each person needs to be outside the city in the fresh air more often. The increased amount of positive ions decreases productivity and causes fatigue.

Ionizer saturates the air in the room or work area with negative ions. Thanks to ionization, well-being and blood circulation improve, respiration is regulated, the intensity of metabolism in the body increases, etc.

In addition, the use of ionizers has a positive effect for diseases of the lungs and respiratory tract, the circulatory system, heart, etc. Ionization prevents the festering of wounds in case of burns.

The ionizer consists of the following parts: screen (chandelier), transistor DC-current converter, power supply device. The screen is actually a negative ion generator. On its needles, under the action of high voltage from the converter, electrons are formed, ionizing the air in the room.

The screen (chandelier) is a light metal ring to which a copper mesh made of bare wire with a diameter of 0.3 ... 0.5 mm is soldered. The mesh has square cells 35 ... 45 mm in size. They form a convex part of the screen directed downward. In the corners of the grid, needles with a diameter of 0.25 ... 0.5 mm and a length of 45 ... 50 mm are soldered, which must be sharp enough. Attached to the ring are three copper wires with a diameter of 0.8 ... 1 mm, rotated at an angle of 120 ° and soldered over the center of the screen. These are high voltage wires. A high voltage (25 kV) is supplied to the screen from a transistor current converter For large premises (classrooms, workshops, etc.), a voltage of 50 kV is required.

The chandelier screen is suspended from the ceiling on insulators. It should be located 2 m from the floor. The current transformer is placed near the screen, and the power supply for the transformer is placed in any convenient place. The chassis must be grounded, for example by connecting it with a wire to a water pipe.

You can use cotton wool to check the operation of the ionizer... If the ionizer is fixed, a small piece of cotton wool should be attracted to the screen-chandelier from a distance of 0.5 ... 0.6 m. Carefully approaching the hand to the needles of the screen, at a distance of 70 ... 100 mm we will feel cold. For an approximate measurement of the number of ions, you can use the device shown in Fig. 1, c. No odors should appear during the operation of the ionizer. The smell indicates the presence of foreign gases (ozone, nitrogen oxides) in the room. In this case, you need to carefully check the design of the chandelier, the installation of the multiplier and the connection of the converter to the chandelier. The ionizer is a high voltage source, so care must be taken when handling it. Although the high voltage current barely reaches 3 ... 5 μA and is not dangerous, touching the screen or high voltage circuit threatens an unpleasant shock.

A very simple air ionizer for your car (and not only) can be built with practically no financial costs, using parts from old equipment. The device is implemented on the basis of a high-voltage voltage converter according to the blocking generator scheme.

The high voltage circuit uses a simple voltage doubler. The converter circuit is relatively simple and contains only one active transistor component. The transistor is not critical, you can use direct transistors of the KT818 series and its analogs, you can also use reverse conduction transistors, for example, KT819, but in this case you will have to change the polarity of the power supply. It is desirable to install the transistor on a heat sink.

The inverter circuit operates over a wide range of supply voltages, starting from almost 1 volt of input voltage.In the multiplier, high-voltage diodes of the KTs106 type and its analogs should be used, the capacitors are not critical, the main thing is that the operating voltage of the capacitors is above 3kV (ideally 5-6.3kV), the capacitance is from 500 to 4700pkF.

The high-voltage transformer is wound on a B30-type ferrite core (dimensions are not critical, the shape of the core is also). The primary winding consists of 2x30 turns of 0.75 mm wire (0.65-1mm wire can be used). We lay on top of insulation made of fluoroplastic or other. material and wind the secondary winding. The winding is wound in layers, each layer of 100 turns of wire 0.05-0.1 mm.

We carefully insulate each layer in order to avoid interlayer breakdowns. It is advisable to fill the finished high-voltage transformer with epoxy resin. For more reliable operation, the high voltage multiplier also needs to be filled with resin.

CAREFULLY . there is an increased voltage at the output of the circuit, it is not dangerous for life, but with direct contact you will receive a strong current shock - quite painful and unpleasant.

The issue of saving today affects different areas of life. Household appliances should be purchased at the store and it is possible to take additional guarantees. Sometimes you should rely on your own strengths and make your family's life more beautiful and healthier. Each person will make an air ionizer with their own hands, you just have to want it. The question is about time, skill, skill and learning. If the question regarding the purchase of an ionizer is resolved, it is worthwhile to understand whether a device is needed.

It is worth answering this question in the affirmative. We noticed that in hospitals there are sessions of air ionization, when doctors do not receive patients at a time. Thanks to the air ionizer, molecules that carry colds and viruses transmitted by airborne droplets break down. Studies carried out by laboratories have revealed an improvement in human immunity and a decrease in the risk of acute respiratory infections by up to 30%, which regularly ionizes the air at home. Doctors prescribe aeroionotherapy to patients to improve their health, and sometimes they interfere with the limitations of such therapy (for children under 3 years of age).

Do not assume that a homemade air ionizer will be worse than one purchased in a store. Theory has not been researched. Ionizers made with my own hands do not differ in meaning from those made at the plant, the difference is in cost savings (from 1000 rubles), time spent and manual work (at factories, ionizers are created by technological lines). If you can't make an air ionizer yourself, you can buy a ready-made and modern one that will fit into the interior of the room.Why do I need an air ionizer in the house:

Fight against morbidity, ionizers have an anti-infectious effect, which is important for families with children of different ages, in kindergartens and schools, in offices, etc.

Strengthening the immune system, which is necessary for young children, whose health has not been strong from birth, the function is useful for the elderly.

Smoothing out foci of inflammation, air ionization demonstrates a positive effect on chronic diseases.

A household air ionizer for the home helps to recover faster and protects the body from diseases (there is a constant risk of catching a cold). For children, air ionization is useful, because rubella, measles and other diseases are prevented. Make sure that children do not play and are not present in the room while the equipment is operating. In addition to maintaining health, the air ionizer fights dust in rooms (stops hovering in the air and settles), eliminates unpleasant odors. Image - DIY air ionizer repair

More and more people prefer not to buy an air ionizer, but to assemble it on their own, there are purchased and home-made devices in an apartment or house that work in about the same way. A true radio amateur can make the ionizer, although a woman can also assemble the device. Consider what materials are needed for assembling the ionizer, depending on the type of apparatus:

Homemade homemade air ionizers are assembled even by beginners. A minimum set is required:

2 plastic containers for toy surprises in chocolate eggs, type "Kinder Surprise".
2 conductors with a diameter of 0.5 mm with a plug.
Plug if the wire is found without it.
Insulation for the core.
Tailoring scissors.
Sewing needle.

It is not necessary to use 2 oval containers, take much more. If the first experiment is ahead, it is worth starting small, the chance of failure of the first experiment is great. The option will turn out to be the simplest, energy-efficient and cheapest. Unlike the next ionizer, this one is incredibly simple and quick to assemble.

To make a car air ionizer, you only need a high-voltage voltage converter and a converter generator. As a generator, it is permissible to choose any option, even a single-contact one. There will be a generator of the old integral timer series "555", simple, will not spoil or even slow down the operation of the ionizer.

Now is the time to learn how to make an air ionizer. It's worth starting with the first ionizer - you can make it with your son as homework in a labor lesson. First of all, collect the necessary materials for assembly, so as not to be distracted in the process in search of the necessary parts and tools.

We collect an elementary homemade air ionizer for the house:

Punch small holes in plastic containers with a needle. However, a small, slightly visible hole is not enough; it is better to create a noticeable hole by rotating the needle.
Take thin conductors and dissolve one core at a time.
Pass the conductors through the plastic containers so that one conductor has a positive "+", in the other container - a negative "-".
Insulate the wires.
Connect the conductors together only after the cores have been insulated.
Connect the design to the network and enjoy.
If necessary, connect the wires with a plug and then connect the homemade ionizer.

Surely there is a wire already with a plug from old broken equipment, for example. If you had to use the plug separately from the wiring, disassemble the plug. When the plug is disassembled, you will see the signed contacts. It remains only to connect the wire to the plug and continue the manufacture of the ionizer. But remember that such an ionizer is easy to break, make a box or shelf for it, put it in an inaccessible place for kids and pets.

The next version of an ionizer for a car is a little more complicated, you need to approach it more carefully and more focused. First, take a power supply unit left over from old technology, for example, from a PC. It is necessary to carefully pull out, or rather, evaporate, the transformer. To make it easier, heat the ferrite with a lighter (do not trust the work of children!), Then use a needle to separate the halves from each other so that they do not crumble or break. Dispose of the old winding, you need to use a new one: primary (14 turns) and secondary (600 turns). Install 2-3 layers of insulation (office tape) between the windings, every 100 turns, i.e. for the secondary winding, do not forget to put 5-6 insulation layers. Connect the timer to the transformer, connect them to the voltage multiplier (collect KTs106 diodes and capacitors up to 10 kW 3300 pF). Now push the output conductors on the voltage multiplier up to 2.5-3 cm and connect to the mains - the specific smell of ozone will tell you about the correctness of the experiment.

If you don't want to make your own ionizer, choose a handy one in the store. The selection can be tricky due to the variety of excellent models. There are two main types of devices for their intended purpose:

The main and professional classification of air ionizers is the list:

classic or effluvial ionizer;
crown;
hydrodynamic;
radioisotope;
thermionic;
photoelectric.

The common man and the buyer can understand the classification: "Chandelier" and compact (mini-) ionizer.The first model is large in size, located either on the wall or on the ceiling, so as not to take up useful space in the room. "Chandelier" is suitable for large rooms, but it is necessary to devote a lot of effort to cleaning, you will have to collect dust often from the floor, walls and furniture, from the needles of the apparatus, of which there are many. The second model, as the name implies, is small in size, transferred from room to room, they are the safest for household use if there are children in the house.

There are combined models of ionizers in small apartments, the functions of air purification or humidification are distinguished in combined ionizers. Thanks to ionizers-purifiers, in addition to saturating the air with charged ions, dust, colds and viruses are removed. The humidity level in the room will help maintain the ionizer-humidifier, which is especially useful in winter when the heating season is in full swing. Combined ionizers easily interfere with the breakdown of odor and smoke storage molecules.

Air ionizers can be used in apartments, offices, automobiles, and suitable for the whole house. The difference allows you to choose the correct power source for the ionizer. Choose an ionizer with a built-in filter that seems to be of high quality and efficient. Filters in ionizers are no less important than devices for saturating the air with clean and free ions. Available in coal, water, photocatalytic and combined (HEPA). Remember to take breaks from work.

The simplest air ionizer designed for cars can be made with your own hands, without investing almost any money in it. All you need are old, unnecessary hardware parts. The principle of operation of the device is based on a high-voltage voltage converter, which will work according to the blocking generator scheme.

How to assemble an ionizer with your own hands?

The converter circuit is simple and affordable; it includes a single active element - a transistor. The choice of transistor is not important. You can use various models, ranging from direct transistors of the KT818 series and ending with reverse conduction transistors, for example, KT819.

You can also use analogs of the models listed above, but you will have to slightly change the circuit and change the polarity of the power supply. When implementing a circuit, it is desirable to mount a transistor on a heat sink.

The range of operation of the inverter circuit is quite wide, the device starts to work already from one volt of the input voltage.

As a multiplier, diodes such as KTs106 or similar analogs should be used, the choice of a capacitor is not critical, the main thing is to pay attention to the fact that the capacitor's operating voltage should be above three kV (ideal - 6 kV), and its capacity should vary within 500 -4700pcF.

A high-voltage transformer is wound on a B30 core, the size and shape of the core do not matter. The first winding consists of 2x30 turns of wire. The wire size should be 0.75mm, but 0.65mm and 1mm wires can also be used. On top of the first winding, it is necessary to lay insulation, which is made of fluoroplastic or any other insulating material, then we begin to make the second winding. It is best to make the winding in layers, each layer should consist of one hundred turns (with a wire of 0.05mm).

In order to avoid interlayer breakdowns, it is necessary to insulate each layer with special care. After the transformer is ready, it is advisable to fill it with epoxy resin.
