<p>An air cleaner includes a housing (12) with a dirty air inlet (20), a clean air outlet, and an interior. A tubesheet (28) is in the housing interior having a plurality of openings (30). A panel-style filter arrangement is oriented such that each one of the openings (30) in the tubesheet is covered by the panel-style filter arrangement. A plurality of blowpipes (40) are provided. Each blowpipe is oriented to direct a fluid pulse at a respective one of the openings (30) in the tubesheet (28) covered by the panel-style filter arrangement. An accumulator arrangement is oriented adjacent to the openings in the tubesheet on a downstream side of the tubesheet. The accumulator arrangement includes, for each opening in the tubesheet, a first and second plate (44) adjacent to opposite ends of the tubesheet opening. Adjacent openings in the tubesheet share a same first or second plate (44). Preferably, each blowpipe is oriented to direct a fluid pulse at a respective one of the openings in the tubesheet covered by the panel-style filter arrangement at an angle that is: (i) not normal to a plane of the openings in the tubesheet; and (ii) not in line with a general direction of filtration flow through the panel-style filter arrangement.</p> |
