FIELD: engines and pumps. ^ SUBSTANCE: dust collection system comprises source of gas subject to treatment, fan, pipelines and two dust collectors on opposite twisted gas flows, every of which is equipped by conical bunker, upper tangential inlet nozzle, inlet vortex, dust baffling conical orifice, with axial outlet nozzle of treated gas and dust exhaust nozzle, in which rotary valve is installed. The novelty here is equipping of dust collection system pipelines by gate valves and arrangement of conical bunker of the first dust collector with nozzle of dust and gas mixture exhaust, besides, source of gas subject to treatment is connected to inlet of fan, delivery nozzle of which is connected to inlet tangential nozzle of the first dust collector and via gate valves to inlet swirlers of the first and second dust collectors. ^ EFFECT: higher efficiency of dusty gas treatment. ^ 2 cl, 1 ex, 1 dwg
