DUST SEPARATOR Russian patent published in 2008 - IPC B04C7/00 

FIELD: mechanics filtration.

SUBSTANCE: invention is designed to separate suspended particles from gases. The dust separator incorporates a countercurrent flow concentrator connected to the vortex chamber outlet axial branch pipe, the concentrator allowing an axial purified gas out coming and a removal of concentrated dust. The vortex chamber is provided with a slot and gas duct with a gate arranged on the chamber curvilinear wall on the flow inlet side, the gas duct communicating with the duct removing the concentrated dust from the countercurrent flow concentrator into the extension countercurrent flow cyclone. The vortex chamber opposite side has a slot and gas duct communicating with the extension countercurrent flow cyclone. The extension countercurrent flow cyclones are equipped with the transit-receiving vessels connected to the gates incorporating the gates with vertical dust standpipes, while the receiving vessel is provided with a dust duct with gate. The proposed invention increases the efficiency of operation.

EFFECT: increase in dust separator efficiency.
