Abstract:
Apparatus comprising:(a) a nozzle assembly which is sized and configured to (i) receive a pressurized liquid and a gas, and (ii) eject said pressurized liquid as a liquid flow while feeding said gas into proximity with the periphery of said liquid flow; (b) a housing defining a suction chamber into which said nozzle assembly may eject said liquid flow, said housing further defining a suction inlet and a suction outlet; (c) an outlet pipe extending from said suction outlet away from said suction chamber, said outlet pipe being configured for fluid communication with said suction chamber and being disposed to receive said liquid flow; said outlet pipe defining at least a first inner diameter along a portion of its length and a second inner diameter along another portion of its length, said second inner diameter being less than said first inner diameter; and (d) a suction pipe, a first end of said suction pipe opening into said suction chamber at said suction inlet, and a second end of said suction pipe opening into the surrounding environment; wherein said nozzle assembly extends into said suction chamber towards said suction outlet and into the imaginary line of flow of said suction pipe.
