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

FIELD: technological processes, filters.

SUBSTANCE: invention concerns gas treatment systems. Dust collection system includes source of gas to be cleaned, fan, pipes, four dust collectors at oncoming swirl gas flows, each collector made in the form of cylindrical case with conical tank, tangential top inlet pipe, inlet swirler in bottom inlet pipe, with axial outlet pipe for cleaned gas and dust discharge pipe in which floodgate is mounted, and dampers in pipes. Conical tank of first dust collector has dust and gas mix discharge pipe. Source of gas to be cleaned is connected to tangential inlet pipe and inlet swirler of first dust collector, axial outlet pipe of which is connected to tangential inlet pipe and inlet swirler of second dust collector. Axial outlet pipe of second collector is connected to inlet swirler of fourth dust collector. Dust and gas mix discharge pipe of conical tank of first dust collector is connected to tangential inlet pipe and inlet swirler of third dust collector, axial outlet pipe of which is connected to tangential inlet pipe of fourth dust collector, and axial outlet pipe of fourth collector is connected to the fan inlet.

EFFECT: enhanced efficiency of dusted gas treatment, especially for fine-dispersed particles.
