US 4,060,587 A · Gaseous and liquid reactant treatment

Abstract

Movable means are provided interiorly of a rotating confined line on a substantially horizontal plane through which reactant fluids, such as liquids and gases, flow and react, whereby inherently to inhibit the adherence of particulate matter within the line and effect enhanced contact and intermingling of the liquid maintained in the form of a pool therein with the gas during rotation of the line. The movable means comprise relatively solid objects which bounce and tumble within the line to contact the interior of the line. The relatively solid objects, which may be in the form of chains, wires, cables or any other solid media whether consisting of separate or joined components, also function to prevent the liquid, maintained in the pool and/or passing through the line from assuming a dry or precipitate state as it is splashed or otherwise distributed about the entire interior periphery of the line. The action of the tumbling media also provides complete contact between the gas and liquid flowing through the line, as well as portions of the liquid maintained in the pool, to achieve the appropriate chemical reaction therebetween for cleansing of the gases. The tumbling media causes the gases to flow in a tortuous path through the confined line and means are provided to maintain portions of the liquid in the pool, and preferably also, to raise and cascade axially extending portions of the liquid from the pool onto the gas and the tumbling media, whereby to provide a conjoint packed tower and spray column type rotating scrubber system.
