AIR PURIFIER Russian patent published in 2017 - IPC F02M35/22 F02M35/08 B01D45/12 

FIELD: ventilation.

SUBSTANCE: air purifier contains an one-piece casing 1 and separational openings 2 located therein, in each of which a swirler of the polluted air flow 3 is placed on the inlet side, and a ring-shaped clamp 4 is provided at the outlet. A dust-collecting pallet 5 with a suction nozzle 6 and intake devices for a purified air 7 is connected to the casing 1. Each intake device for the purified air 7 is placed with a clearance inside the outlet section of the separational opening 2 that forms a circular duct 8 for the dust discharging into the dust-collecting pallet 5. The height of the air purifier is determined in accordance with the diameter of the separatinal opening 2 and with the outside diameter of the intake device for the cleaned air 7 in the area of the dust-collecting pallet 5 according to the formula Ha.p.=(2.55÷2.76)⋅(D+d), where Ha.p. - is the height of the air purifier, D - the diameter of the separational opening 2, and d - is the outer diameter of the intake device for purified air 7 in the area of the dust-collecting pallet 5. In this case, the ring-shaped clamp 4 placed at the outlet of each separational opening 2 is conjugated with the wall of the separational opening 2 with a cone-shaped surface 9 between the diameter of the separational opening 2 and the inner diameter of the ring-shaped clamp 4.

EFFECT: high purifying efficiency.
