ABSTRACT:
Apparatus arranged in a closed system for removing particulate matter and gases from a polluted gas stream that includes a sorbent particulate charging and injection gun for electrostatically charging sorbent particles and injecting them into a polluted gas stream to charge and agglomerize pollution particulates therein, the stream flowing into a collection system housing that contains a series of moving and static bed filters and provides for operations at pressures less than atmospheric, and at temperatures up to two thousand (2000) degrees F. The filter beds are maintained across the housing and spaced apart from front to back therein, each filter containing a media material selected for removing the charged agglomerized pollution and sorbent reacted particulates and reacting with gases in the polluted gas stream, providing for removal thereof to clean that gas stream that is then vented to atmosphere. At least one and preferably a plurality of moving bed filters are arranged in the collection system housing, each, in turn, receiving and passing the gas stream therethrough, which filter beds each include rotary airlock and rotary valves for maintaining a closed system and preventing infiltration of outside air within the housing while still allowing new media materials to be added and vented out of the filter, and including a static filter bed or beds arranged as the last filter bed or filter beds in the series that provides for a removal of any remaining pollutants from the gas stream prior its venting to atmosphere.
