Pressure generator/gas scrubber

Apparatus for generating pressure and scrubbing gas comprising:

• a casing having a scroll casing;
• a gas outlet, tangential to and in fluid communication with said scroll casing, and at least one liquid outlet;
• rotating means for generating a positive pressure and for scrubbing gases supplied to said casing, said rotating means including a plurality of radially extending feed tubes positioned in said scroll casing, each tube having an open outlet end and an inlet end;
• liquid supply means for supplying liquid to said inlet ends of said feed tubes;
• said casing further comprising gas inlet supply means for supplying a gas to said casing at a position adjacent said inlet ends of said feed tubes, wherein said gas supply means includes at least one gas inlet box positioned on one side of said scroll casing and in fluid communication with a central portion of said scroll casing, each said gas inlet box including a gas supply inlet;
• and
• drive means for rotatably driving said rotating means such that said liquid exiting from said feed tubes rotates along a peripheral arc of said scroll casing, and said gas outlet is located in said scroll casing substantially along a tangent to said peripheral arc, wherein said liquid ejected from said open outlet ends of said feed tubes pulls said gas adjacent said inlet ends into scrubbing contact with said liquid and results in formation of said positive pressure at the gas outlet of said casing, with said scrubbed gas exiting through said gas outlet and said liquid exiting through said at least one liquid outlet.
