The technical solution relates to methods of ozonization of air and can be used to clean and improve the ozone-ion content of the air in residential areas.

Usually in the air of residential areas contain a variety of toxic impurities and the concentration of useful ions ozone does not exceed a few units in cm3, while in the air resorts concentration of such ions is about 2-5 thousand units in cm3[1, 2].

Found that ozonation of air helps to clear this air [2, 3]. Typically, the ozone synthesize either directly in the volume of the room (for example, ultraviolet irradiators [3]), or injected into the volume directly from the ozonizer [2, 3] (prototype). In both cases, the ozone synthesize due to the excitation of oxygen molecules. However, are generated and toxic impurity - oxygen molecules in the singlet excited state (singlet oxygen, which is extremely reactive and abnormally long-lived in the air [4]) and oxides of nitrogen, which pollute the processed air. Moreover, once in the volume of air, oxides of nitrogen initiate the catalytic decomposition of ozone and secondary pollution of this air singlet oxygen [4]. Another disadvantage of the prototype is the difference in the ratio of ozone and its ion is in the ozonized gas from the optimal values thousands of times. Thus, known methods of ozonization of air does not allow you to create and maintain indoor air superior ozone-ionic structure, characteristic of the air resorts.

Solved the technical problem of the invention is to develop a method and device for creating and maintaining in the air of dwellings improved ozone-ionic structure.

The solution of the technical problem in the way ozone air accommodations, including the input of ozone in the ozone gas in the volume of air accommodations, is achieved by the fact that the ozonized gas cleanse, enrich negatively charged particles and injected into the volume of air accommodations dosed and given the scope of this volume.

The ozonized gas can be purified and enriched with negatively charged particles through the implementation of the intensive interaction of the gas with water.

Intensive interaction ozonized gas with water may be effected by passing the gas through a volume of water.

Passing ozone gas through a volume of water can be carried out while the water in a compressed and the compressed layer of the particles of the sorbent.

The volume of water through which is passed the ozonized gas can be prone to vibration.

The ozonized gas can be introduced into the volume of air is elago space in the lower part of this room.

In the introduction of ozonized gas in the volume of air accommodations may be generated air flow.

The solution of the technical problem in the device ozonation air accommodations, containing the ozonizer is achieved by additionally introduced cleaner and enrichment ozonized gas negatively charged particles, the inlet of which is connected to the output of the ozone generator, and the output is connected with a drain area of the input ozonized gas in the volume of air accommodations.

Cleaner and enrichment ozonized gas negatively charged particles may be in the form of faucet water and ozonized gas.

Faucet water and ozonized gas can be filled with water in the contact tank, the lower part of which is placed a bubbler connected to the output of the ozone generator.

The volume of water may be placed in compacted and compressed layer of particles of the sorbent.

The layer of particles of sorbent and the bubbler can be placed in the volume of water in a removable cartridge with a perforated lid and bottom.

Contact capacity may be fitted with a lid and a drain connecting the space directly below the cover with the input area ozonized gas into the air accommodations.

The bubbler can be made in the form of a long porous tube, coiled in a PLoS is th spiral.

In the upper and lower parts of the contact capacitance can be made pipes for filling and draining the water, closed lids.

The ozone generator can be placed in ozone compartment, made in contact capacity.

Ozone compartment can be placed in the lower part of the contact tank and provided with a channel connecting the compartment with the upper part of the contact vessel.

The ozonizer can be made with the possibility of vibration and placed in ozone compartment without hard contact, and the contact vessel may be equipped with a shock-absorbing support legs.

The essence of the method consists in the following.

In a domestic ozone generators ozonopause gas is air. The main pollutants that are made in the ozonized gas ozone are nitrogen oxides (NO, N2O, NO2, NO3N2O5) and singlet oxygen [4, 5]. In the presence of ozone is extremely fast conversion of all oxides of nitrogen nitrogen dioxide N2O5[5]. Because water N2About5easily dissolves with the formation of nitric acid, HNO3that is miscible with water in any ratio, the solubility of N2O5(and, hence, other oxides of nitrogen) in water is very high. Therefore, when interacting with water ozonated gas is cleaned of all oxides and the PTA, moreover, the degree of purification with time, not worse.

Otherwise there will be absorption of ozone. Gases, as a rule, are well soluble in water only in that case come with water in a chemical reaction (for example, as the N2O5). Ozone enters into chemical interaction only with the impurities in the water and is therefore characterized by a relatively low solubility in pure water. Therefore, there is a rapid (within 10-15 minutes) saturation of water with ozone and correspondingly rapid increase in the concentration of ozone in the ozonized gas, peered with water.

The lifetime of singlet oxygen in water decreases in the hundreds of millions of times compared to the time of his life in a gaseous environment [4]. Therefore, when the interaction of the gas with water is effective quenching of singlet oxygen contained in the gas.

At the contact of the gas and water in a thin (of the order of the diameter of the molecule) layer between them there is a double dielectric layer. The formation and destruction of this layer (for example, by passing the gas through a layer of water) dielectric with a lower dielectric constant, that is, the gas is charged negatively. Therefore interact with water in the gas is enriched with particles of negative polarity ions of water vapor [1]. Part of these ions when interacting with a much polielektrolitami ozone, possessing a very strong electron affinity, is transformed into negative ions ozone mechanism

where O3- ozone, M-- negative ion water vapor, O3-ion ozone, M - a particle of water vapor. Since the ionization process ozone is accompanied by a significant release of excess energy (O3+e→3--50 kcal/mol), transformation [1] is energetically favorable (any energy of the system tends to move to the state with the lowest potential energy). Therefore, the probability of this transformation is very high. It also follows that ions ozone, firstly, more stable than ozone. This allows them to carry a negative electric charge to the blood and reduce its viscosity (this explains therapeutic action of ozone), to improve its saturation dissolved oxygen (solubility ions ozone ten times more than oxygen). This reduces the risk of heart attacks and strokes, blood cells get a chance to pass through the narrowest capillaries and improve breathing and feeding areas of the body, etc. secondly, the absence of excess energy means the absence of ion ozone toxic properties, which qualitatively distinguishes it from toxic ozone. Thus, when wsimages is under water ozonated gas is enriched with negative ions ozone (due to mechanism (1)) and becomes less toxic. This contributes to the improvement of the ozone-ion composition of the ozonized gas.

When you enter purified and enriched with negatively charged particles ozonized gas into the air accommodations is:

- improvement of the ozone-ion composition of the air by dilution of the injected gas in which the concentration of ozone and ions are high, and the ratio of these concentrations is improved;

clearing the air accommodations ozone;

clearing the air accommodations water vapor injected gas. They are involved in cleaning the air, entering into a chemical bond with nitrogen oxides and by quenching singlet oxygen. The advantage of the proposed method is that the ozone and water vapor are introduced together. Indeed, with this input water vapor, on the one hand, removed from areas of concentrated ozone, nitrogen oxides catalytically decomposing ozone, and thereby improve the cleaning efficiency of the air injected ozone and reduce the allocation of singlet oxygen. On the other hand, these pairs are effectively quenching of singlet oxygen generated during the cleanup;

- improvement of the ozone-ionic composition of air through the following transformation of the composition of the ions of water vapor. Ions of water vapor from getting into the air and absorbed cha what tics aerosols (dust), give them their negative charge. And these aerosol particles, in turn, transfer their charge to the ozone mechanism

where O3- ozone. T-- heavy negative ion, O3-ion ozone, T - particle aerosol. This leads to the improvement of the ozone-ion content of the air by increasing the useful ions ozone and simultaneous reduction of harmful heavy ions. The speed of this transformation is described by the expression

v=0,056·C·N-,

where v is the velocity of ionization (ion/cm3·h), With the ozone concentration (µ g/m3), N-the concentration of heavy negative ions (ion/cm3). For example, when C=25 g/m3(the concentration of ozone in ambient air), N-=15000 ion/cm3(typical value of N-in the air, enriched with ions of water vapor) in the air for 1 sec 5 are formed of light negative ions ozone in 1 cm3that is a very significant addition to the overall balance of ions ozone (it is estimated that as a result of the cumulative action of natural ionizers in the outer atmospheric air for 1 sec formed about 10 light negative ions in 1 cm3).

Thus, when implementing the proposed method raises the possibility of effective cleaning with ozonized gas and a sharp decrease of the SC is to grow the catalytic decomposition of ozone, hence, the secondary air pollution. This raises new channels effective ionization ozone mechanisms (1) and (2)allowing to transform toxic (but useful in small doses)ozone into its ions (useful in any amount), and thereby to establish and maintain in the air of dwellings improved ozone-ionic structure. The possibility of such transformation is based on the exceptional ability of ozone to join him electrons and "take" them from negatively charged particles.

In the proposed device the ozone-ionic structure is optimized adjustment parameters of the gas-water mixer and intensity of interaction of ozone gas with water (for example, a change in the flow rate Bartiromo gas), characteristics of the ozonizer and the duration of ozonation, site selection and enter the ozonized gas in the volume of this air, etc.

Enter the ozonized gas in the lower part of the room, creating an air stream in the scope of this input contribute to a more uniform distribution of introduced gas in the volume of the room.

When placed in a volume of water interacting with the ozonized gas, a layer of particles of the sorbent, first, the gas is purified not only from nitrogen oxide and singlet oxygen, but most of the other contaminants due to the absorption of their sorbent is. Secondly, the interaction of ozone gas with water is more intense, which improves as the purification of the gas, and the enrichment of its negative ions. This improvement significantly increases the compaction and compression of the layer of sorbent particles, since this duration, the surface and the intensity of contact of the gas with water and the particles of the sorbent increased many times over. Is also a decrease in the concentration of ozone in the ozonized gas due to ozone absorption sorbent. However, this decrease will be small, because of the combined water layer and the sorbent dramatically decreases the absorption of the sorbent of ozone is passed through the layer of gas.

The vibration of the water present in the layer of particles of sorbent and interacting with ozonized gas, improves the mass transfer between them and enhances the formation and destruction of double layers. All this improves the cleaning and ozone-ionic composition of the gas.

The drawing shows an example of the implementation of the proposed device for carrying out the proposed method of ozonizing air accommodations. The device contains the ozone generator 1, the purifier and the enrichment of ozonized gas negatively charged particles made in this case in the form of mixer 2 water and ozonized gas inlet 3 which is connected to the output 4 of the ozone generator 1, and the output 5 from the Dinan using a drain 6 input area ozonized gas in the volume of air accommodations. In this example, the mixer 2 water and ozonized gas made in the form of a water-filled 7 of the contact vessel 2, the lower part of which is placed bubbler 8 connected to the output 4 of the ozonizer 1. In the contact vessel 2 is placed compacted and compressed layer of sorbent particles 9. In this example, the bubbler 8 (made in the form of a long, porous and coiled in a flat spiral tube) and a layer of sorbent particles 9 is placed inside the contact vessel 2 in a removable cartridge 10 with a perforated cover 11 and bottom 12. Contact tank 2 provided with a cover 13 and a drain 6, connecting the space directly below the cover 13 with the input area of the ozonized gas in the volume of air accommodations. In the upper and lower parts of the contact vessel 2 made pipes for filling and draining the water, closing caps 14, 15. The ozone generator 1 is placed in ozone compartment 16, performed inside the contact vessel 2. In this example, ozone compartment 16 is placed in the lower part of the contact vessel 2 and provided with a channel 17, which connects the compartment 16 with the upper part of the contact vessel 2. The ozonizer 1 made with the possibility of vibration and placed in ozone compartment 16 without hard contact, and the contact tank 2 is equipped with a shock-absorbing support legs 18.

Consider the implementation of the proposed method using the device, izobrazennogo the drawing. The ozone generator 1 through the air filter 19 takes the air, ozonium and presses it through the porous wall of the bubbler 8 and the combined water layers 7 and sorbent particles 9. While the ozonized gas 20 is cleaned from toxic ingredients and is enriched with negative ions, including ions and ozone. Further purified and concentrated with ozonized gas 20 to the drain 6 is withdrawn from the contact vessel 2 and is introduced into the volume of air accommodations specified in the scope of this volume. The location of this area and the amount of injected gas is determined from the condition in which the concentration of ozone in the air we breathe does not exceed the norm.

When placing an ozonizer 1 within the contact tank 2: damped vibration and noise characteristic of domestic ozone generators, and these vibrations and noises improve the purification and enrichment of useful ions ozonized gas 20 (i.e. a negative feature of domestic ozone generators used in this case use); the proposed device becomes more compact and comfortable; improving the cooling of the housing of the ozone generator 1.

Example 1. Through the volume of the water 7 in the contact vessel 2 with a diameter of 16.4 cm and a height of 33 cm was passed the air with a flow rate of 2-6 l/min, ozone in the ozone generator 1 performance 5 mg O3/hour. When the transmission of the concentration of nitrogen oxides can be reduced is ilaci eight times and was always less than background levels (less than 20 g/m 3), the ozone concentration decreased in the steady state by 20%. With the continuous introduction of the gas into the room with a volume of 60 m3at a height of less than 0.3 m from the floor level ozone in the air we breathe was about 22 g/m3. While in the air we breathe, in comparison to the outside air, the content of light negative ions has increased about ten times and was about 1000 ion/cm3.

Example 2. In the contact vessel 2 from example 1 in the amount of water 7 was placed compacted and compressed layer of particles of activated charcoal brand BAU-MF production of JSC "Sorbent" (a, Perm). In this example, in comparison with example 1, the concentration of nitrogen oxides in ozonized air decreased by one-half the concentration of light negative ions in the air we breathe has increased by 100% and amounted to 2000 ion/cm3the content of ozone in the air we breathe was 18 ág/m3. It follows that the accommodation in the volume of water 7 compacted layer of particles of sorbent 9 significantly improves the ozone-ion composition of inhaled air.

Thus, the results of the tests confirm the findings of the above analysis.
