BAG FILTER Russian patent published in 2005 - IPC

FIELD: equipment for removing suspended solids from gas flows.

SUBSTANCE: bag filter comprises body, filtering sleeves, at least one sleeve grating arranged in the body and connection pipes for securing the sleeves. Connection pipes define polygons in the grating cross-section. Sides of polygons mate each other. Connection pipe cross-section areas decrease in direction away from the grating up to reaching constant cross-section area value defined by that of the sleeve. Sleeve grating is formed as a single unit or is made of several connection pipes connected one to another. The sleeve grating and connection pipes defining it are produced of flexible material. Shapes of sleeve grating and connection pipes are maintained by support grating having orifices. Orifice shapes correspond to that of connection pipes in sleeve grating cross-section. In the case of sleeve location above the sleeve grating gaps are created between mated connection pipe walls. The gaps are provided with flaps, wherein flexible connection pipe ends extending below the sleeve grating may be used as the flaps.

EFFECT: reduced material consumption and labor inputs for filter production, decreased mass, simplified regeneration.
