DIRECT-FLOW CYCLONE Russian patent published in 2009 - IPC B04C3/00 

FIELD: technological processes, filters.

SUBSTANCE: invention is related to dust collection devices. Cyclone comprises cylindrical body, swirler fixed on fairing and installed at the inlet, opening for separated phase, louver unwinder in the form of revolution solid with unwinding vanes and vane arranged in the form of elastic plate installed in window of cylindrical body, cone-cylinder adapter. Swirler fairing is arranged as conic. Louver unwinder is arranged in the form of truncated cone with taper of 1:10-1:11. Swirler fairing, cone of louver unwinder and cone-cylinder adapter are serially connected by means of fixed butt joints. Adapter is arranged with the possibility of its fixed coupling along cylindrical surface with internal surface of cyclone cylindrical body downstream opening for separated phase relative to inlet into cyclone in axial direction. Larger base of conic fairing is coupled with smaller base of louver unwinder cone, larger base of which is coupled with smaller base of cone-cylinder adapter cone. On swirler surfaces that contact with cleaned medium, and on valve surface coupled with window of cylindrical body, hydrophobic coating is arranged.

EFFECT: provision of efficient and reliable operation of cyclone.
