The invention relates to medical and household appliances and can be used to create a refreshing microclimate in a room by ionizing the air and also cleaning it from dust and aerosols.

Devices for ionizing air are known. Their disadvantage is the lack of elements for air purification from various impurities entering the air as a result of the activities of industrial plants, transport, and the city.

A device is known for both ionization and air purification. Its disadvantage is the low degree of air purification due to the intense release of ozone with increasing voltage on the electrodes of the electrostatic precipitator of the device.

The purpose of the invention is to increase the degree of air purification.

The goal is achieved by installing an additional electrode in the output pipe,

connected to the positive terminal of the power source and the location of the flow driver, made in the form of a fan, between the electrodes of the outlet pipe.

The drawing shows a longitudinal section of the device.

The device comprises a chamber 1 with inlet 2 and outlet 3 nozzles, an exhaust fan 4 installed in the outlet nozzle, ionizing electrodes 5, 6, 7, made in the form of grids and placed in the planes of the cross sections of the inlet and outlet nozzles, a potential precipitation electrode 8, made in the form of a bath filled with water, a positive electrode 9, a high voltage power supply 10 to which electrodes are connected.

The device operates as follows.

pipe 3 and from it into the room passes the air flow. The electrodes 5 and b give the particles of dust and other aerosols in the stream a negative charge. A positive potential is applied to a potential precipitation electrode 8, the function of which is performed by a water-filled bath.

When the flow moves over the surface of the water, negatively charged particles are attracted to the surface of the water due to the interaction of electrostatic forces. They are removed from the stream.

An exhaust fan creates a discharge region above the surface of the water, facilitating the active deposition of negatively charged particles. The section of the chamber above the precipitation electrode is larger than the section of the outlet and inlet pipes. This circumstance reduces the speed of passage of the flow over the surface of the water, reduces the kinetic energy of the charged particles, and increases the residence time of particles in the area of the precipitation electrode. Because of this, the rate of deposition of particles on the electrode increases, and air cleaning is more efficient.

The air stream from the precipitation electrode 8 enters the outlet pipe 3 and enters the electrode 9. A positive potential is applied to it from the power supply 10. This potential neutralizes the residual G-negative charge of the air flow, decreasing the degree of ozone formation at the last ionizing electrode 7 in the direction of the flow, on which the ionization of neutral rather than excited particles occurs. The intensity of the corona discharge, which is the reason for the formation of ozone, is reduced, and this leads to a decrease in the release of ozone into the air stream coming from the outlet pipe 3 into the room in which the device is treated with air.

Reducing ozone formation allows increasing the voltage at the electrodes 5 and 6, thereby increasing the degree of air purification. Dedusted, purified stream

air, passing further through the device, is ionized to a hygienic norm and enters the room, improving the aeration composition, while simultaneously providing its humidification and reducing bacterial

contamination.

In some cases, a working fan of the device can be an unacceptable noise to others. To maintain the operability of the device with the fan turned off, an additional electrode 11 is installed between the fan 4 and the ionizing electrode 7, to which a negative potential is applied. Electrode 11 helps increase ion

flow directed towards the outlet of the device, providing a minimum hygienic rate of ionization of the room.
