Abstract
A portable dust collector comprises a rectangular box-shaped housing containing a rectangular box shaped filter chamber having a dust collection volume in a lower portion thereof and providing plenums for operative gas circulation in a compact environment. The filter chamber shares a portion of the floor with the housing and has a pair of internal parallel sidewalls spaced inwardly from the outside sidewalls of the housing. The internal sidewalls define a plurality of filter chamber dirty gas inlets located just under an apertured cell plate from which the filters hang. The system is provided with a pulse jet cleaning system located in the clean air plenum above the cell plate.
Claims18
A portable dust collector comprising
- a road, sea or train-transportable rectangular box-shaped housing having a first end and a second end, a pair of opposed parallel sidewalls, a roof and a floor all extending between the first end and the second end, an endwall sealing the second end, and an end closure sealing the first end, said housing defining at least one dust collector gas inlet for admitting gas to be filtered and at least one dust collector gas outlet for exhausting filtered gas,
- a rectangular box-shaped filter and dust-collecting chamber positioned in a lower portion of the rectangular box-shaped housing, said filter chamber sharing a portion of the floor of the housing and being partly bounded by a pair of parallel sidewalls spaced inwardly from the sidewalls of the housing,
- said sidewalls defining a plurality of filter chamber dirty gas inlets, an apertured cell plate spaced inwardly from the roof of the housing forming a ceiling for the rectangular box shaped filter and dust-collecting chamber,
- wherein a pair of lateral dirty gas distribution ducts is defined between the opposed parallel sidewalls of the housing and the opposed pair of parallel sidewalls of the filter chamber, and a dirty gas flow path is formed between the lateral dirty gas distribution ducts and the at least one dust collector gas inlet, and
- wherein a clean gas plenum is defined between the cell plate and the roof, and a clean gas flow path is formed between the clean gas plenum and the at least one dust collector gas outlet.
A method for converting a shipping container into a filter dust filtration unit, comprising
- dividing an inside of the container into an upper portion and a lower portion with an apertured cell plate and ceilings, the apertures of the cell plate providing flow communication between the upper portion and the lower portion of the thus divided container,
- positioning a filter chamber in the lower portion of the container beneath the cell plate, said chamber containing a plurality of filters hanging from the cell plate and arranged in rows and columns, said chamber being spaced from the shipping container sidewalls to define two longitudinally extending dirty gas plenums extending alongside the filter chamber, with a plurality of dirty gas apertures leading from the longitudinal dirty gas plenums and into the filter chamber at spaced locations between the rows of filters next to the cell plate,
- positioning an inlet duct and lateral distributor to provide for flow of dirty gas into the dirty gas plenums,
- positioning an exhaust fan to draw gas through the filters and provide for flow of dirty gas from the inlet duct to the dirty gas plenums, and through the spaced dirty gas apertures and into the filter chamber, and clean gas flow through the upper portion of the container and past the exhaust fan.
A method for filtering dust comprising
- introducing a dust-laden gas stream into a first end of a rectangular box shaped housing,
- routing the dust-laden gas stream into a rectangular box shaped filtration chamber positioned near the opposite end of the housing, in a lower portion of the housing,
- flowing the gas stream from the filtration chamber upwardly through filters into a clean gas plenum positioned in an upper portion of the housing, and discharging the clean gas stream from the rectangular box shaped housing.
