CYCLONE-FILTER FOR CLEANING DUST-LADEN GASES Russian patent published in 2000 - IPC

FIELD: chemical, food, and metal-working industries. SUBSTANCE: cyclone- filter has case with conical bottom, tangential pipe union for admitting dust-laden gas flow, dust outlet pipe union, exhaust pipe, and filter. Exhaust pipe functions as filter and at the same time as clean gas outlet pipe union; it is, essentially, welded structure partially made of porous cermet that rotates in bearing assembly by means of its windwheel thereby affording additional gas filtering by passing it through side surface and bottom end. Proposed device ensures continuous reconditioning of exhaust-pipe filtering surface, effective separation of gas-dust systems due to increasing radial component of dust particle speed, rather low resistance due to relatively large filtering surface area, reduced space requirement due to using working volume of cyclone for dust-laden gas treatment. EFFECT: facilitated manufacture, improved reliability. 3 dwg
