SPIRAL-CONICAL CYCLONE Russian patent published in 2008 - IPC B04C9/00 

FIELD: technology of dust collecting.

SUBSTANCE: cyclone contains case, composed of cylindrical and conical parts, spiral inlet of gas flow, made in form of inlet branch pipe, dust-outlet hole and exhaust pipe, on the end of which filtering element, whose hydraulic resistance constitutes not more than 50% of hydraulic resistance of the whole apparatus, is fixed. Filtering element represents filter-chuck, made in form of cylindrical rod framework with upper and lower flanges, on which by means of belts, placed in plane, perpendicular to axis of framework, filtering element is fixed. On the upper blind flange of filter-chuck regeneration system of filter-chuck is placed. Bunker for dust collecting is made of conical or pyramidal form with angle of walls inclination, exceeding angle of natural slope of collected dust, and is connected with sluice feeder or mobile reservoir for dust collecting. Filtering element is made in form of corrugated conical covering.

EFFECT: increase of efficiency and reliability of dust collecting process.
