VORRICHTUNG ZUM EINBRINGEN VON GASEN IN FLUESSIGKEITEN, INSBESONDERE ZUM BELUEFTEN VON ABWAESSERN

摘要

An apparatus for introducing gases into liquids, for instance for aerating sewage water in a container, comprises a liquid duct 1 which communicates with a circulation pump, a duct 2 which guides oxydising gases such as air, and outlet nozzles 7 for expelling the liquid/gas mixture into the container. Tubes 3 are connected to radial openings of the liquid duct and pass through the gas duct. The tubes have nozzle-like constrictions in their portions disposed within the gas duct and suction openings 6 for the gas distributed over their periphery. The tubes further have, at their free ends, the outlet nozzles 7 for expelling the gas/liquid mixture produced within the gas duct.
