DEVICE FOR REMOVING DUST WITH THE HELP OF MOISTURE, HAVING MULTIPLE MECHANISMS OF ACTION, USING WATER CIRCULATION AND DUST REMOVAL METHOD Russian patent published in 2020 - IPC B01D47/06 

FIELD: personal articles and house appliances.

SUBSTANCE: invention relates to dust separation, in particular to wet dust removal device using water circulation and dust removal method. Proposed device comprises dust collection device, dust separation device and air/water separation device, water circulation device and dust discharge device. Dust collection device includes an impeller dust removal drum (2) and at least one section of coaxial multi-ring tip (6) located along axis inside drum (2). Ventilating holes are distributed along tube wall of each section of nozzle (6). Upper end of drum (2) is equipped with filtration inlet (1). Lower end of drum (2) is connected to device for dust settling and separation of air/water. Device for dust settling and separation of air/water comprises annular gas/water discharge chute (7) tightly connected with lower end of drum (2). It also includes a discharge tube of annular chute (8) and water settler (10) located below annular chute of gas/water discharge (7). Lower part of chute is equipped with drain hole (20). Upper end of the outlet pipe of annular chute (8) is connected to drain hole (20), and the lower one goes to water settler (10). Discharge tube for concentrated dust-containing water (9) is located along annular chute axis for gas/liquid discharge (7). Lower end of tube (9) is connected to water settler (10), and upper end comes from upper end of water settler (10). Upper end of discharge pipe (9) is located below annular chute for discharge of gas/liquid (7), and its outer diameter is greater than inner diameter of annular chute (7) or is equal to it. Water circulation device includes overflow chute (11) located outside from upper end of water settler (10) and connected to its upper end. Overflow gutter (11) is connected to the reservoir of clean water (12). Reservoir (12) is connected to upper end of tip (6) by means of water pump (13). Dust discharge device is assembled in the form of an inclined upward spiral transporting tubular structure (15). Its lower end is connected with lower end of water settler (10). Tube wall on the side of the lower end of the structure opposite water settler (10) is equipped with a water outlet channel (19) projecting outwards. This channel is connected to water settler (10) by means of channel for recirculating water (18).

EFFECT: increased efficiency of dust extraction, provision of water saving, prevention of secondary contamination and danger of spontaneous ignition.
