Abstract:
A device for causing contact between a gas and a liquid, comprising:(a) a first chamber having two parallel wall members with a plurality of inclined wall members arranged transversely between said two parallel wall members to separate the gas and liquid into a gas region and a liquid region wherein alternating wall members of said plurality of wall members have a plurality of openings;(b) a plurality of guide members located on the sides of said alternating wall members being adjacent to the liquid region, said guide members having inlets disposed on said openings on said alternating wall members and outlets extending into the liquid region, wherein relative movement between the liquid and the wall member causes a venturi-effect at the outlets drawing gas from the gas region through the openings in said alternating wall members, said guide members directing the gas drawn through the openings into the liquid region in a direction corresponding to the direction of movement of the liquid with respect to the wall member to form elongated gas bubbles in the liquid;(c) a plurality of openings in at least one of said parallel wall members, said openings being disposed in the gas regions for supplying gas to the gas regions; and(d) a plurality of openings in at least one of said parallel wall members, said openings being disposed in the liquid regions, said openings providing an outlet for gas and liquid from the liquid regions, said openings being adjacent to a second chamber for receiving the outlet gas and liquid, said second chamber partially filling with liquid to form a liquid seal during operation.
