Hauptmann, E G

A gas scrubber is provided which is particularly useful for scrubbing flue gas and condensate effluent from a kraft pulp mill. The scrubber comprises a first chamber having inner and outer looped parallel side walls, and first and second end walls extending therebetween. A gas inlet is positioned so as to direct gas passing through it between the side walls. Fluid nozzles on the inner wall are directed to spray liquid toward the outer wall. A gas outlet is provided which has at least a portion angularly spaced from the gas inlet. The walls of the first chamber are preferably arranged to provide an incremental volume between them which decreases with angular distance from the gas inlet. The gas outlet is dimensioned so that the velocity of the gas flowing between the walls is substantially constant. Preferably, the side walls are concentric, substantially circular and each of constant diameter. In addition, the first end wall is substantially planar and the second end wall is helical in configuration. A plurality of interconnected adjacent, concentric, toroidal chambers are also usefully provided in a sequence extending radially inwardly from the first chamber.
