ABSTRACT:
A gas treatment apparatus suitable for removing sulfur oxides and dust from gas streams is disclosed. The gas to be treated is conveyed through a conduit and past at least one nozzle positioned in fluid communicaton with the interior of the conduit. The nozzle injects an atomized solution, such as an alkali metal carbonate solution, into the gas. Solids formed by contacting the gas with the solution collect on the inner surface of a conical funnel-shaped portion of a hollow body. The hollow body includes a conduit portion in coaxial alignment with the hollow body. The solids are first removed from the hollow body by a screw conveyer positioned on the conical funnel-shaped portion and then withdrawn through a solids exit port. Gases formed by the contact of the gas with the injected solution are removed through a gas exit port in the hollow body and a gas passageway defined by the inner surface of the hollow body and the outer surface of the conduit portion.
