Abstract
A pollution control system for removing harmful elements from industrial smoke streams comprises a reciprocating pump assembly that draws smoke from a furnace or the like and delivers it through a passageway where the smoke is treated sequentially to remove harmful elements therefrom. Disposed along the passageway is an atomizer station, a first fibrous filter, an ignition chamber, and a second fibrous filter. Having traversed the passageway, the smoke is ejected into a large tank of water and bubbles to the surface thereof, thus being further cleansed. From the water tank, the cleansed smoke stream moves up a stack, through a final fibrous filter, and into the atmosphere where it poses a substantially reduced environmental hazard.
