SEPARATION DEVICE OF SOLID SUBSTANCE AND GAS, AS WELL AS CEMENT PRODUCTION PLANT Russian patent published in 2013 - IPC F27B15/00 B01D45/12 B04C1/00 

FIELD: machine building.

SUBSTANCE: separation device of solid substance and gas includes a rising pipeline for transportation of gas/solid substance suspension with a solid substance supply opening and a gas supply opening, a downtake screw-type and/or spiral pipeline, in which gas/solid substance suspension is divided into a solid substance flow and a gas flow. Besides, the device includes an angle-head that attaches the rising pipeline to the screw-type and/or spiral pipeline, solid substance pipeline that is interconnected with the end of screw-type and/or spiral pipeline for removal of solid substance flow, as well as a gas line for removal of gas flow, which is interconnected with the end of screw-type and/or spiral pipeline. The angle-head has the first form of cross section in the connection zone with the rising pipeline, and the second form of cross section in the connection zone with screw-type and/or spiral pipeline. At least one elbow in the pipeline direction is provided in the zone of the angle-head.

EFFECT: invention allows improving separation degree.
