The invention relates to a solution for enriching a liquid with oxygen. For this purpose, oxygen from the ambient air is introduced into the liquid by means of an injector and is partially dissolved in it. The liquid which leaves the injector, and which is laden with dissolved and undissolved gas components of the air, is then introduced into at least one degassing unit (2), which is connected downstream to the injector, for the removal of undissolved gas components that form bubbles in the liquid. According to the invention, the injector involves a multiple injector having at least two injector chambers (11, 12, 13, 14). In the degassing unit (2), undissolved oxygen is first separated from the liquid through an intense vortexing of the liquid, and then is once again introduced into the liquid in an injector chamber (13, 14), by aspirating it out as part of a gas-liquid mixture via a return line (18, 18′) of a multiple injector (1), this line connecting the at least one degassing unit (2) to an intake port (6′, 6″) of the related injector chamber (13, 14). The undissolved, difficultly soluble gas components of the air, i.e., undissolved nitrogen in particular, are discharged via a gas discharge valve of the degassing unit (2). |
