ELECTRICAL AIR CLEANER Russian patent published in 2017 - IPC B03C3/10 

FIELD: electricity.

SUBSTANCE: device comprises a housing with an inlet and outlet openings for air passage, an endless belt drive with top and bottom pulleys, an electrode group consisting of corona electrode and collecting electrodes in the form of endless belts powered by the drive pulleys, the second cleaning area - a precipitator, located behind the corona electrode in the direction of the air movement. The precipitator is formed by an electrode group composed of paralleled equidistant collecting electrodes in the form of endless belts powered by the drive pulleys. In the space between the collecting electrodes there are channels are for the air passage, a repelling electrode in the form of an electrically conductive plate is located in each channel parallel to the nearest collecting electrodes and equidistant from them. A potential of the same polarity as the potential of the corona electrode is supplied to the repelling electrode. The amount of collecting electrodes of the precipitator is two or more. The cleaner additionally comprises liquid tanks, while the bottom slave driven belt pulleys of the collecting electrodes are immersed in the tanks, and the belts of the collecting electrodes are made with the possibility of withholding on the surface of a liquid layer. The corona electrode is made in the form of a wire or a rod. The power supply device is configured to provide a potential difference from 10 to 100 kW and with the possibility of providing a potential difference between the repelling and collecting electrode determined by the corresponding relationship.

EFFECT: high quality of air cleaning is provided, the amount of harmful gases is reduced, the efficiency of collected particles recycling is increased, and the operating costs are reduced.
