The present invention relate to techniques for the production of hydrated ions and can be used to improve the microclimate, maintaining a comfortable concentration of ions in the room, as well as hospital wards, medical complexes, workplaces and classrooms, living rooms. In addition, the invention can be used to combat the harmful manifestations of static electricity.

A known method of generating a charged aerosol (Sitnikov A.G. Formation and evolution of non-equilibrium aerosol in a gas of atmospheric pressure corona-streamer electric discharge. The dissertation on competition of a scientific degree of candidate of physical-Mat. of Sciences, Tomsk, 2006, p.10), namely, that in the system of electrodes excite the crown-streamer discharge, and serves the area of the discharge gas containing an unsaturated hydrocarbon vapor mixture. In the area of the discharge is initiated by the formation of aerosol that enters the buffer aerosol chamber and through an outlet fitting in the main aerosol chamber. The device carrying out the known method, contains a high-voltage pulse generator connected to the electrode system of the coaxial line. The electrode system consists of a grounded cylindrical body and the high voltage electrode, consisting of parallel codes is checked. Steam source includes a pump, control valve and bubbler liquid hydrocarbon.

The disadvantage of this method and device is the complexity and high cost of installation, due to the use of expensive working medium (CO2and cryogenic installations for low temperatures. It makes extensive use of the known method and device.

Closest to the proposed method is a method of producing a charged aerosol formations, namely, that produce water vapor, served in a chamber with an exit nozzle, which creates a corona discharge, and release the charged aerosol cloud through the nozzle (NR. Bolotov, J.V. weaver. The spectral characteristics of the spark discharges in artificial charged aerosol formations/Electromagnetic phenomena, v.3, №2 (10), 2003, s-238).

Closest to the proposed device is a generator of the charged aerosol carrying out the known method and containing the steam generator, the camera with the output of the profiled nozzle installed in a grounded electrostatic screen. Along the axis of the nozzle has a needle-like electrode tip in the critical section of the nozzle, which is connected to the high voltage source of negative polarity. The steam generator representing promotionalcodes, connected to the camera device through the heated steam, which is the offset of moisture vapor. (NR. Bolotov, J.V. weaver. The spectral characteristics of the spark discharges in artificial charged aerosol formations/Electromagnetic phenomena, v.3, №2 (10), 2003, s-238).

A disadvantage of the known method and device is the low efficiency of generation of hydrated ions and the low reliability of the device. In the case when the incoming steam is overheated (has a degree of dryness pair x≥1), the resulting pair of ions have high mobility, are deposited on the walls of the nozzle or in the proximity of the nozzle area of the screen and the external zone come in limited quantities (carry current generator of hydrated ions is extremely small).

In the case when the steam in the chamber is wet (degree of dryness pair x≤1), loop-through insulator 5 inside the chamber is covered with a liquid film, it loses its insulating properties, conductivity occurs on the surface of the insulator, the voltage drops, the corona discharge is stopped, and the outflow of ions is absent. Even if you take steps to increase the strength of the insulation, the presence of a liquid dispersed phase in the nozzle with corona leads to the shielding zone of the crown and the generator does not tolerate hydrated ions in the external zone, i.e. the generator lane who ceases to work effectively.

The objective of the invention is to enhance reliability and efficiency of generation of hydrated ions. The technical result consists in providing a degree of dryness of steam is equal to the unit.

The problem is solved in that in the method of producing a hydrated ions, namely, that produce water vapor, served in a chamber with an exit nozzle, which creates a corona discharge and release the hydrated ions through the nozzle, controlling the steam pressure and temperature in the chamber, and the temperature is set depending on the steam pressure in accordance with the formula T=72-4P2+R, where T is the temperature in degrees Celsius, p is the pressure in the chamber at the bars.

Device for the generation of hydrated ions, including the source of water vapor, which is connected via concealer humidity chamber, coaxially coupled to the shielding electrostatic screen, shaped nozzle with a needle electrode mounted along the axis of the nozzle tip in a critical section of the nozzle and connected passing through the insulator to the high voltage source, contains the processor and the temperature sensors and pressure established in the chamber, and the outputs of the sensors connected to the inputs of the processor, the output of which is connected to the corrector humidity pair.

The degree of dryness pair x=1 is ensured by the fact that the temperature is ur in the camera set depending on the vapor pressure in accordance with the formula

T=72-4P2+R found empirically, where T is the temperature in degrees Celsius, p is the pressure in the chamber at the bars.

The introduction of pressure sensors and temperature of steam in the chamber provides the control of these parameters, and the introduction processor allows you to control the degree of dryness of steam and set it equal to the unit in accordance with the above formula.

The figure shows a diagram of the device for generation of hydrated ions.

The device contains a source of water vapor 1, which is connected through the corrector pair of 2 camera 3. High-voltage output from a high voltage source 4 passing through the insulator 5 is connected to the needle electrode 6 that is installed along the axis of the profiled nozzle 7 of the chamber 3 with an edge in the critical section of the nozzle. Electrostatic screen 8 coaxially coupled to the nozzle 7. The camera is mounted a pressure sensor pair 9 and the temperature sensor 10, the outputs of which are connected to the CPU 11, the output of which is connected to the corrector moisture vapor. Generator output steam flow of ions 12. Steam source 1 can be made of the electrode or in the form of boiler superheated steam, and the corrector 2 humidity - in the form of an electric superheater or throttle.

Method of producing a hydrated ions is carried out as follows. The source of steam 1 verbatime the pairs, through the corrector humidity pair 2 is supplied to the camera device 3. In needle electrode 6, corona discharge occurs when applying thereto a high voltage from the power source a 4-conductor passing through the insulator 5. Steam flowing from the nozzle 7, is charged in the corona discharge and in the outer zone of the generator occurs stream 12 of hydrated ions (water molecules). Using the pressure sensor 9 and the temperature sensor 10 are controlled pressure and temperature of steam in the chamber 3. The sensors 9 and 10 are received in the CPU 11, which controls the operation of the corrector 2 humidity, causing the temperature in the chamber is set in accordance with the formula T=72-4P2+R, where T is the temperature in degrees Celsius, p is the pressure in the chamber at the bars.

The camera 3 is installed dryness pair x=1, which provides the necessary mobility of hydrated ions. Ions are not deposited on the walls of the nozzle 7 and in the proximity of the nozzle area on the electrostatic screen 8, at the same time in the nozzle is formed of a dispersed liquid phase, and charged in a corona discharge ions are carried in the outer zone of the generator. The generator works effectively and carry current is almost equal to a current of the corona discharge in the nozzle.

This improves the efficiency of generation of hydrated ions and reliability of the work of the generator.
