Abstract
The invention discloses a filter cylinder type dedusting unit, which comprises a box body, an air inlet and an air outlet that are disposed on the box body, a box body partition plate and filter devices, and an ash cleaning device. Each filter device comprises an inclined core tube, air guide plates, a filter cylinder, a venturi and a Venturi horn mouth. The upper end of the core tube is a forward protruding taper, a cavity exists between the core tube and the filter cylinder, and the venturi and the box body partition plate are in fixed connection. The Venturi horn mouths added in the invention drive the clean air current around the Venturi horn mouths enter the filter cylinder together, thus increasing the air current entering the filter cylinder, and at the same time increasing the air current stability. Therefore, the air current can act on the filter cylinder evenly, and can completely clean out the ash attached to the filter cylinder outer surface without damaging the of the filter cylinder.
