Abstract (en)

[origin: WO8602577A1] A device is used to continuously introduce a gas into a liquid, in a flotation, deinking unit or the like. The liquid comes out of an endless ring passage (6) which is completly free of internal obstacles such as limiting walls or the like, and flows after absorbing the gas into a radial diffuser (14), wherefrom the gas bubble-enriched liquid comes out and flows into the treatment container of the plant. For this reason, a single gasification device centrally arranged close to the bottom of the container is sufficient for circular cross-section treatment bath. A swirling flow may be obtained by a deflection in the area of the diffuser or of the first chamber of liquid in the ring passage.
