DUST COLLECTION SYSTEM Russian patent published in 2009 - IPC B04C7/00 B01D50/00 

FIELD: technological processes.

SUBSTANCE: invention concerns gas treatment systems. Dust collection system includes source of gas to be cleaned, pipes, fan, three dust collectors at oncoming swirl gas flows, dampers and conical separation concentrator installed in the pipes, concentrator containing cylindrical swirl chamber connected to inlet chamber with tangential inlet. Swirl chamber encases axial pipe for discharge of gas flow with lesser dust concentration, pipe outlet located at the swirl chamber side opposite to inlet chamber. Swirl chamber surface carries side pipe for discharge of gas flow with larger dust concentration. Source of gas to be cleaned is connected to tangential inlet of separation concentrator, side pipe of which is connected via dampers to tangential inlet pipe and inlet swirler of first dust collector. Axial outlet pipe of first collector is connected to tangential inlet pipe of third dust collector via a damper and to side pipe of separation concentrator via dampers. Axial pipe of concentrator is connected to tangential inlet pipe and inlet swirler of second dust collector, axial outlet pipe of which is connected to inlet swirler of third dust collector and to axial outlet pipe of separation concentrator, while axial outlet pipe of third dust collector is connected to suction pipe of fan.

EFFECT: improved gas treatment efficiency, convenience of maintenance.
