Abstract
An aeration apparatus includes an injection nozzle provided at one of the open ends of a main body formed in the shape of a cylinder. When the injection nozzle is immersed in a liquid, the main body stands upright such that the injection nozzle is on a lower side, and gas is injected inside the main body from the injection nozzle to disperse the gas. The injection nozzle is disposed such that a center line of an injection port formed at the tip of the injection nozzle intersects the inner flow channel surface at a position lower than a blade member disposed in the lowest stage, and such that the angle formed between the center line and the vertical direction is not greater than 45 degrees.
Claims4
An aeration apparatus comprising:
- a main body formed in a shape of a cylinder with open ends, the main body having inner flow channel surface with a pentagonal cross-sectional shape;
- a plurality of blade members provided in multiple stages on the inner flow channel surface, the plurality of blade members having different orientations;
- and
- an injection nozzle one of the open ends of the main body,
- wherein the injection nozzle is configured to be immersed in a liquid with the main body standing upright such that the injection nozzle is on a lower side, and gas is injected inside the main body from the injection nozzle so as to disperse the gas;
- and
- the injection nozzle is configured such that a center line of an injection port formed at a tip of the injection nozzle intersects the inner flow channel surface at a position lower than a blade member, from among the plurality of blade members, at a lowest one of the multiple, and such that an angle formed between the center line and a vertical direction is less than or equal to 45 degrees.
