Method of and apparatus for cleaning gases

Claim 1

An apparatus for cleaning a gas contaminated by dust and like particles, comprising an outer casing in the shape of a right rectangular prism the lower end of which forms a vessel having liquid therein, a vertical inlet channel through which the contamined gas to be cleaned is passed downwardly, said channel being defined by one wall of said casing and a vertical partition disposed within and extending the whole width of said casing, the lower end of said partition being inwardly curved to constitute an inwardly curved part extending toward an opposite wall of said outer casing, a deflector disposed within and extending the whole width of said casing, said deflector arranged substantially in prolongation of said curved part but spaced from said curved part to form a gap therebetween, said curved part and said deflector being spaced above the liquid in said vessel and cooperatively constituting a substantially horizontal nozzle therebetween having a narrowmost portion adjacent said gap, said deflector having an curved upwardly part, and an outlet channel from said nozzle being formed between said upwardly curved part of said deflector and said opposite wall of the casing, said inwardly curved part of said vertical partition and said deflector defining a chamber in communication with said outlet channel, said upwardly curved part of said deflector having a top free edge for triggering in said chamber a rotating vortex and directing a portion of the latter to enter said gap, moving thereat in a same general direction as the contaminated gas passing through said nozzle for wetting a portion of the incoming contaminated gas which passes through the nozzle without contacting the surface of the liquid, a baffle on said opposite wall of the outer casing and extending into said casing aboVe said chamber towards said vertical partition and forming a constriction therebetween and between said upwardly curved part in said casing so that gas flowing up through said casing is forced to follow an S-shaped path, and said baffle being oriented over said chamber so that liquid collecting thereon will drop off said baffle into said chamber, a drip separator disposed above said baffle in said casing, and a rotor means at an outlet portion of said casing for drawing the gas through said apparatus.

Claim 2

An apparatus for cleaning a gas contaminated by dust and like particles, comprising an outer casing in the shape of a right rectangular prism the lower end of which forms a vessel having liquid therein, a vertical inlet channel through which the contamined gas to be cleaned is passed downwardly, said channel being defined by one wall of said casing and a vertical partition disposed within and extending the whole width of said casing, the lower end of said partition being inwardly curved to constitute an inwardly curved part extending toward an opposite wall of said outer casing, a deflector disposed within and extending the whole width of said casing, said deflector arranged substantially in prolongation of said curved part but spaced from said curved part to form a gap therebetween, said curved part and said deflector being spaced above the liquid in said vessel and cooperatively constituting a substantially horizontal nozzle therebetween having a narrowmost portion adjacent said gap, said deflector having an curved upwardly part, and an outlet channel from said nozzle being formed between said upwardly curved part of said deflector and said opposite wall of the casing, said inwardly curved part of said vertical partition and said deflector defining a chamber in communication with said outlet channel, said upwardly curved part of said deflector having a top free edge for triggering in said chamber a rotating vortex and directing a portion of the latter to enter said gap, moving thereat in a same general direction as the contaminated gas passing through said nozzle for wetting a portion of the incoming contaminated gas which passes through the nozzle without contacting the surface of the liquid, a baffle on said opposite wall of the outer casing and extending into said casing aboVe said chamber towards said vertical partition and forming a constriction therebetween and between said upwardly curved part in said casing so that gas flowing up through said casing is forced to follow an S-shaped path, and said baffle being oriented over said chamber so that liquid collecting thereon will drop off said baffle into said chamber, a drip separator disposed above said baffle in said casing, and a rotor means at an outlet portion of said casing for drawing the gas through said apparatus.
