FILTRATION OF FLOW CONSISTING OF GAS AND PARTICLES Russian patent published in 2019 - IPC B01D45/04 F02C7/52 

FIELD: technological processes.

SUBSTANCE: invention relates to a device for filtration of a gas flow carrying particles of liquid or solid substance in a flow channel. Device (10) for filtration of gas flow includes flow channel (12), including narrowed section (22), which is continued by expansion (24) in direction along flow direction, diverting channel (14) having inlet hole (32) located inside flow channel (12) so that it is in fact on one axis with narrowed section (22), on its continuation downstream. Diverting channel (14) and flow channel (12) are arranged so that the flow circulating in the diverting channel is less than the flow circulating in the flow channel. In flow channel (12) downstream of inlet hole (32) of diverting channel (14) there are obstacles for particles flow, wherein obstacles (38) for flow of particles include a buffer installed across flow channel (12). Buffer (38) comprises transverse walls (40, 42, 44) formed one after another along flow channel (12) and containing non-aligned holes. Wall (42) is located opposite channel (50) for particles suction, which enters into flow channel (12).

EFFECT: efficient filtration.
