ASPIRATION SYSTEM WITH OSF (ONCOMING SWIRLING FLOW) APPARATURS AND FRAME FILTER Russian patent published in 2011 - IPC B01D50/00 

FIELD: process engineering.

SUBSTANCE: invention relates to wet dust separation and may be used in chemical, textile, light industries, etc, for dusty gas cleaning. Proposed system comprise swirl dust separator and filter. Vorject dust separator comprises cylindrical housing 4 with comical bin and inlet branch pipe 5 and 6 arranged at bin bottom to terminate in larger diametre cylinder 7. Housing top accommodates secondary flow feed branch pipe and outlet branch pipe 3. Face surface of cylinder 7 accommodates shutter-type swirler 9, spinner 9 and bumper washer 10. Outlet of clean gas 3 accommodates air duct secured thereto and communicated with inlet branch pipe 23 of frame sleeve filter. Filter comprises housing 17, filtration section 21 with boxes 22 and 23 for dusty gas intake and clean gas discharge, filtration sleeves 16 with frame 19, tubular grating, dust collection bin 18 and regeneration mechanism. The latter consists of solenoid valve 11, compressed air feed pipe 12, Venturi nozzle 14 and regeneration automatic control device 15. Filter comprises also temperature pickup, dust collector dust level alarm pickup, thermal automatic annuciator detector and manifold with nozzles to be connected to fire fighting system incorporating control unit arranged in filtration section outlet box, their outlet being connected to common microprocessor.

EFFECT: higher efficiency of dust separation.
