Claims

[Scope of claims for utility model registration] (1) An inlet and an outlet are provided at both ends of a cylindrical container,
At least one spiral-shaped right-handed screw and one left-handed screw are fixed coaxially and alternately spaced apart from each other at a predetermined interval, and the outer edges of both screws are in close contact with the inner wall of the container. A gas-liquid mixing device. (2) A container is formed by fixing flanges with an inlet or an outlet communicating with the interior to both open ends of the cylindrical container body, and a support rod coaxially arranged at the center of the container. Both ends are fixed to both flanges, and a band-shaped plate is wound and fixed in a spiral shape between the support rod and the inner wall of the container in a close state to form a screw, and the screw is rotated clockwise at a predetermined interval. A gas-liquid mixing device characterized in that a plurality of gas-liquid mixing devices are formed alternately in a counterclockwise direction. (3) The raw solution sucked in gas by the ejector is pressurized by the pressure pump, and together with the compressed gas generated by the compressor, an inlet and an outlet are provided at both ends of the cylindrical container, and a spiral clockwise screw is installed inside. and at least one counterclockwise screw are fixed coaxially at predetermined intervals alternately, and the outer edges of both screws are supplied to the inlet of the gas-liquid mixing device in close contact with the inner wall of the container, A dissolved solution is created by mixing and dissolving gas in the gas-liquid mixing device, and the dissolved solution flowing out from the outlet is led to and stored in a tank from which surplus gas contained in the dissolved solution can be released, and the solution is stored in the tank. A device for generating fine bubbles, characterized in that the solution can be appropriately taken out by reducing the pressure from the supply port. (4) The micro-bubble generating device according to claim 3, which is a registered utility model, wherein the pressurizing pump is a vortex pressurizing pump equipped with an impeller.
