Abstract
[Problem] To enable an increase of fine bubbles in medium liquid. [Solution] A suction device of the present invention includes a cylindrical portion that is formed of a cylinder with two base surfaces, first surface and second surface, and that flows medium liquid supplied from a plurality of paths, from the first surface toward the second surface, a plurality of introducing portions that introduce the medium liquid from the first surface or from the vicinity of the first surface into the cylindrical portion such that the medium liquid swirls inside the cylindrical portion, and an outlet port provided at or in the vicinity of the center of the second surface.
Claims25
A fine bubble generating apparatus comprising:
- an electrolysis unit that electrolyzes raw water to produce electrolyzed water and cracked gas;
- a gas-liquid delivery unit that mixes the electrolyzed water and the cracked gas and delivers mixed liquid;
- a first pipe that supplies the mixed liquid from the electrolysis unit to the gas-liquid delivery unit in a hermetically sealed state;
- a fine bubble generating unit that generates fine bubbles in the mixed liquid supplied from the gas-liquid delivery unit, by physical collisions;
- a second pipe that supplies the mixed liquid from the gas-liquid delivery unit to the fine bubble generating unit in the hermetically sealed state;
- and
- a pump that is provided in the second pipe and that pumps the mixed liquid to the fine bubble generating apparatus under pressure.
The fine bubble generating apparatus according to claim 1, wherein:
- the gas-liquid delivery unit includes
- a cylindrical portion that has a cylinder with two base surfaces, a first surface and a second surface, and that causes medium liquid supplied from a plurality of paths to flow from the first surface toward the second surface,
- a plurality of introducing portions that introduce the medium liquid from the first surface or from vicinity of the first surface into the cylindrical portion such that the medium liquid swirls inside the cylindrical portion, and
- an outlet port provided at or in vicinity of a center of the second surface.
