ABSTRACT:
A smoke-stack filter device comprising a plurality of dual-corrugated-plate members disposed at circumferentially spaced apart relationship to one another in an annular space between a pair of coaxially arranged cylinders, said corrugations arranged such that they define a plurality of serpentine passageways extending longitudinally of the cylinders for flow of polluted gases upwardly therethrough, and a treatment liquid flows in a substantially constant quantity down from the top of said members along the corrugated surfaces of said members to form a liquid curtain to wash pollutants from polluted gases and flowing upwardly through the serpentine passageways between the adjacent corrugated members, the downwardly flowing treatment liquid carrying pollutants dissolved or suspended therein to a draining chamber, and the clear filtered gases flowing upwardly to and through vents at the upper ends of the passageways.
