Title:
METHOD AND DEVICE FOR ENRICHING A LIQUID WITH OXYGEN
Document Type and Number:
WIPO Patent Application WO/2012/146241
Kind Code:
A3
Abstract:
In order to enrich a liquid with oxygen, oxygen from ambient air is introduced by an injector into the liquid and partially dissolved therein. The liquid leaving the injector is then fed to at least one degassing unit (2) arranged downstream of the injector for removal of undissolved gas fractions. The injector is 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 by vigorous vortexing thereof and then introduced again into the liquid in an injector chamber (13, 14), by drawing it by suction as a part of a gas-liquid mixture via a return line (18, 18') of a multiple injector (1), said return line connecting the at least one degassing unit (2) to a suction port (6', 6") of the injector chamber (13, 14) in question. The undissolved or less easily dissolved gas fractions of the air are discharged via a gas outlet valve of the degassing unit (2).
