ABSTRACT:
A hopper gas distribution system (10) is provided for dispersing particulate laden gas in an equal flow rate around or into a plurality of filter bags (16) maintained in a bag house above a hopper housing (12). Particulate laden gas enters the hopper housing (12) through an inlet conduit (18) and is directed in an upward vertical direction (24) by a plurality of turning vane members (30) mounted within the hopper housing (12) in a longitudinally displaced as well as vertically displaced manner, each with respect to the other. Below the turning vane members (30) and the inlet conduit (20) is mounted a plurality of blocking vane members (42) secured to opposing transverse sidewalls (32 and 34) of hopper housing (12). The blocking vane members (42) create a false bottom floor which further impedes particulate laden gas from passing down into a lower section of the hopper housing (12). In this manner, the particulate laden gas is driven upwardly around or into the filter bags (16) in a uniform manner throughout the cross-sectional interior area of the baghouse (14).
