METHOD OF AIR PURIFICATION Russian patent published in 2013 - IPC F24F3/16 

FIELD: ventilation.

SUBSTANCE: purified air is supplied through the pipe 2 to the upper chamber 9 of the housing 1. At that, passing through the discharge electrode 13 the air is ionised and it charges the dust that is in the air. The charged dust particles move in the direction to the electrodes 6 having a positive potential which turn conjointly with the wheel 4. Having reached the surface of the electrodes, the particles are deposited on them. When the wheel 4 reaches the position when the upper blades are located symmetrically relative to the vertical axis, in the chamber 9 an enclosed volume is created, which is limited by the blade-electrodes and the upper part of the housing 1. In this volume the air portion is finally purified and the noise accompanying the purified air is reduced. Simultaneously the third blade-electrode holds the lower vertical position in the chamber 10 where it is freed from contaminants by feeding to the electrode and the rollers 7 of the similar high potential.

EFFECT: simplification of the design that implements the method and increase of effectiveness of the degree of air purification, reduction of the noise level.
