Patent ID: 6884284

Claim:
An apparatus for rectification of liquid mixtures or for scrubbing of gases, said apparatus comprising an elongated processing chamber extending in a substantially horizontal direction, means for supplying liquid into the processing chamber at a first end thereof, means for discharging a liquid from the processing chamber at an opposite, second end thereof, liquid application means arranged at the bottom of the processing chamber and extending along at least a major part of the length of the chamber for repeatedly throwing supplied liquid transversely to the longitudinal axis of the processing chamber, means for supplying gas into the processing chamber and means for discharging gas from the processing chamber so as to obtain a generally counter-current movement of liquid and gas through the processing chamber, the liquid application means comprising a rotor defining liquid collecting pockets or chambers opening in the direction of rotation, wherein the liquid application means further comprise an upwardly open liquid channel extending axially along the lower part of the processing chamber and having opposite ends, which are in communication with the liquid supplying means and the liquid discharging means, respectively, at least the lower part of the rotor being arranged within the liquid channel, wherein the liquid application means comprise a liquid receiving chamber or channel for receiving liquid flowing downwards along the inner peripheral wall of the processing chamber, the receiving chamber communicating with the liquid channel via an adjustable, longitudinally extending opening or slot, wherein the liquid receiving chamber is defined between the peripheral inner wall of the processing chamber and a flap or plate member being pivotal about a longitudinal axis so as to allow adjustment of a space defined between the lower edge of the flap member and the adjacent part of the inner wall of the processing chamber.
