Abstract (en)
[origin: EP0204688A2] 1. A device for aerating liquids comprising : a rotor (2) whose rotational axis is vertical and which is disposed near the bottom of a tank and which intakes air and liquid ; and a stator (4) which extends around the rotor (2) and has a closed ring of right-angled cross-section flow ducts (8) each having an entry for the liquid-air mixture, the flow ducts (8) being inclined relatively to the radial direction in the direction of rotation of the rotor (2), characterised in that the flow ducts (8) are separated from one another by wedge-shaped gaps whose vertices are disposed between the immediately adjacent inlets, and the vertical boundary surfaces of each flow duct (8) either extend parallel to one another or converge or diverge at an angle of at most 7 degrees.
