Abstract
A device for the enrichment of a liquid stream with a gas is provided including a flow mixer (14) with a venturi nozzle (36), having a rotationally symmetrical contraction (40) with a diameter D and being flown through axially by the liquid stream. The invention additionally includes a gas feed for the lateral feed of the gas into the contraction (40) of the venturi nozzle (36). The gas feed includes at least one gas channel (54, 54′) with a diameter d<0.5D, ending laterally in the contraction (40) of the venturi nozzle (36) in a way, such that the elongated longitudinal axis (56, 56′) thereof is tangential to an imaginary cylinder surface (58), which is coaxial to the contraction (40) and has a diameter D′>d.
