Abstract
An air cleaner is provided including a housing having a dirty air inlet, a clean air outlet, and an interior. A tubesheet is in the housing interior and has a plurality of openings. The tubesheet is oriented in one of either a generally horizontal or a generally vertical position. A plurality of panel-style filters is provided, with each filter being mounted in a respective one of the openings in the tubesheet. The air cleaner also has a plurality of blowpipes, with each blowpipe being oriented to direct a fluid pulse at a respective one of the panel-style filters at an angle that is: (i) not normal to a plane of the openings in the tubesheets; and (ii) not in line with a general direction of filtration flow through the respective panel-style filter. A method of pulse cleaning panel-style filters oriented in openings of a tubesheet is provided. The method includes directing fluid pulses at each of the panel-style filters at angle that is: (i) not normal to a plane of the openings of the tubesheet; and (ii) not in line with a general direction of filtration flow through the panel-style filters. The panel-style filters are oriented in the tubesheet, and the tubesheet is oriented in o…
