Abstract:
[Problem] To provide aeration equipment that breaks gas that has been released in a liquid into fine bubbles so as to uniformly disperse the gas, and efficiently stirs the liquid. [Solution] Aeration equipment (1) is provided with: a main body (10) that is formed in a cylindrical shape with both ends open, and has an inner flow passage with a pentagonal cross section; blade members (24) disposed in multiple stages in the inner flow passage, said blade members having different orientations; and an injection nozzle (32) disposed on one of the open ends of the main body (10). The injection nozzle (32) is immersed in a liquid, with the main body (10) made to stand upright in such a manner that the injection nozzle (32) is at the bottom, and gas is injected inside the main body from the injection nozzle (32) so as to disperse the gas. The center line (C) of an injection port (32a) formed at the tip of the injection nozzle (32): intersects the inner flow passage at a position lower than the blade member (24) positioned at the lowest stage; and is positioned in such a manner that the angle formed between the center line (C) and the vertical direction is not more than 45 degrees.
