Modular filter system with shake and pulse cleaning for dusty enclosures

A removable magazine assembly for filter cartridges comprising an aperture plate defining a plurality of apertures, a plurality of tubular filters hanging from the apertures, one per aperture, a vibrator attached to the aperture plate, a dirty gas distribution means supporting the aperture plate and positioned to distribute dirty gas laterally from a peripheral location with respect to the filters to locations between the filters, said dirty gas distribution means comprising a pair of parallel tunnels spaced apart from each other and nozzles to direct dirty gas from the tunnels to between the filters, and four side walls attached to the dirty gas distribution means and extending in a direction normal to the aperture plate and peripherally to the plurality of tubular filters to form an open-bottomed box having a height sufficient to contain the tubular filters, wherein each tunnel is defined by a tubular sidewall having opposite top and bottom walls, and outer and inner walls, and the top wall supports the aperture plate.

A magazine for filter cartridges comprising an aperture plate defining a plurality of apertures, a plurality of tubular filters hanging from the apertures, one per aperture, a vibrator attached to the aperture plate, a dirty gas distribution means positioned to distribute dirty gas from a peripheral location with respect to the filters, said dirty gas to distribution means comprising a first pair of parallel tubular sidewalls forming a pair of tunnels spaced apart from each other, and a second pair of tubular sidewalls connecting the ends of the first pair, and four side walls attached to the dirty gas distribution means and extending in a direction away from the aperture plate and peripherally to the plurality of tubular filters to form a box having a height sufficient to contain the tubular filters, and an end closure on the box opposite the aperture plate to form a dust collection chamber for collected dust, said magazine for filter cartridges being positioned on a bin and forming at least a partial ceiling for the bin and being removable as a unit from the bin for disposal of collected dust along with the unit.
