APPARATUS FOR CONDUCTING CHEMICAL AND/OR PHYSICAL REACTIONS BETWEEN SOLID SUBSTANCE AND GAS Russian patent published in 2012 - IPC F27B15/00 B01D45/12 B04C1/00 

FIELD: chemistry.

SUBSTANCE: apparatus has at least one helical and/or spiral pipe in which there is separation of a suspension of gas and solid substance into a stream of solid substance and a gas stream through centrifugal forces. The apparatus also has at least one separation chamber connected to the end of the helical and/or spiral pipe, said separation chamber being connected to a gas pipe for removing the gas stream or formed by part of the gas pipe. The separation chamber is connected to a pipe for removing the stream of solid substance. The helical and/or spiral pipe is connected to the separation chamber tangentially at an angle α of at least 30° to the horizontal, and the cross-section of the separation chamber in the connection zone is 0.5-1.5 times greater than that of the helical and/or spiral pipe.

EFFECT: invention provides high degree of separation with relatively low pressure loss.
