Abstract:
1. A dust-collecting apparatus, said apparatus comprising: first and second housing modules configured to be joined longitudinally to create a housing having a transverse panel dividing the housing into an inlet chamber and an outlet chamber, with the panel having a plurality of openings therein; a plurality of elongate filter elements each having an open end and a closed end, with the filter elements being mounted to the panel such that the open ends are in registry with respective ones of the openings in the panel and the filter elements extend into the inlet chamber; and a reverse pulse cleaning apparatus configured for periodically directing a reverse pulse of air through each of the panel openings and into the open ends of the respective filter elements, wherein one of the housing modules includes an inlet opening that communicates with the inlet chamber for admitting dust-laden air and one of the housing modules includes an outlet opening that communicates with the outlet chamber for exhausting clean air, and wherein the housing module that includes the inlet opening further includes an inlet baffling system comprising a plurality of baffle plates disposed proximate the inlet opening and which are configured to facilitate a cross flow air profile for the dust-laden air, and wherein the baffle plates are spaced apart from each other and each baffle plate has a substantially vertical orientation such that a direction of flow of the dust-laden air is substantially parallel to a planar surface of the baffle plate.
