DEVICE FOR CLEANING GAS FLOW Russian patent published in 2006 - IPC B04C5/08 B01D45/12 

FIELD: separation.

SUBSTANCE: device comprises housing provided with chamber. The inlet branch pipe is mounted in the top section of the chamber along its vertical axis. The flow generator made of a cone with curved surface underlies the branch pipe. The curved surface together with the curved surface that conjugates the wall of the inlet branch pipe with the inner wall of the chamber defines a passage that deflects the inlet flow to the inner curved wall of the chamber. The bottom edge of the flow generator forms the exit of the passage made of a ring slot nozzle . The curved wall of the chamber transforms the flow from the ring slot nozzle into the near-wall toroidal vortex. The bottom section of the chamber is converging downward. The collector underlies the chamber. The inlet section of the outlet branch pipe for discharging the cleaned air is arranged along the axis of the chamber at the center of the near-wall toroidal vortex.

EFFECT: enhanced quality of cleaning and simplified structure.
