High capacity gas filter system

摘要

A high capacity gas filter having a particulate collector hopper having a bag housing mounted thereon with the walls of the housing extending outwardly and upwardly from the hopper. The walls terminate in gas passages which may be covered by outwardly extending hoods open at the underside thereof so as to provide for entrance of the dirty air. This opening extends substantially the entire periphery of the housing. A rigid tube sheet having orifices therein extends across the top of the bag housing and rigid frames support bag filters extending downwardly below the orifices and into the housing. A clean air plenum is mounted above the rigid sheet and is connected to a blower for pulling air through the gas passage, downwardly and inwardly along and through the filters and into the clean air plenum. This configuration permits a lower velocity air input and thus provides a higher air-to-cloth ratio while substantially reducing bag deterioration.
