Abstract

A scrubber for exhaust gases comprises a series of nested counter-flow passages including a hot plenum having a star-shaped section. Exhaust gases from the hot plenum surge through a liquid bath and flow in a reverse direction through an inclined array of flat, overlapping, spaced mixing vane s, causing turbulence in the exhaust gases and the formation of highly disperse d tiny bubbles, which enhance the solution of gaseous pollutants into the scrubbing liquid. Mist eliminator vanes strip entrained liquids from the exhaust gases. The hot plenum, reheats the exhaust gases to an unsaturated level. The scrubber is highly effective in reducing particulate matter, stripping sulphur dioxide and nitrogen dioxide from exhaust gases, and reducing the heat signature and visual evidence thereof.
