Abstract:
1. A system for decontaminating industrial output gases, comprising: a gas input flue; a filter housing having an input end, an output end opposite the input end, and a length therebetween, the gas input flue communicating with the input end of the filter housing; a first plurality of planar filters and a second plurality of planar filters, the filters being disposed transverse to the length of the filter housing and located between the input and output ends thereof, the first plurality of filters and the second plurality of filters being alternately positioned at active positions within the filter housing and inactive positions external to the filter housing so that the second plurality of filters is positioned external to the filter housing when the first plurality of filters is positioned within the filter housing, and the second plurality of filters is positioned within the filter housing when the first plurality of filters is positioned external to the filter housing, wherein the plurality of alternating first and second planar filters are successively paired in progressively decreasing filtration coarseness and wherein in the filter housing, a first filter of the first plurality of filters is separated from a second filter of the first plurality of filters by a section for accommodating a first filter of the second plurality of filters; a plurality of filter wash nozzles disposed externally to the filter housing, the filter wash nozzles being adapted to selectively wash the plurality of filters disposed external to the filter housing; and at least one fan communicating with the output end of the filter housing, the fan drawing gases from the gas input flue and through the filter housing and filters positioned within the filter housing.
