WATER TREATMENT PLANT Russian patent published in 2011 - IPC B01D36/00 

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning of mechanical impurities. Proposed device comprises casing with purified fluid discharge branch pipe and asymmetric tapered bottom, cover with initial fluid branch pipe, cylindrical filter element housing hollow insert made up of paraboloid of revolution, hydraulic cyclone and jet apparatus. Said hydraulic cyclone is arranged on bottom outer surface to communicate via feed branch pipe with purified fluid discharge branch pipe arranged at bottom lower section and, via vertical discharge tune, with insert inner cavity. Jet apparatus is arranged in initial fluid branch pipe to communicate via suction tube with insert inner cavity. Taper cavity between filter element walls and insert top section communicates with initial fluid branch pipe while insert bottom section communicates with bottom inner cavity.

EFFECT: higher efficiency of treatment.
