<P>PROBLEM TO BE SOLVED: To provide a fine air bubble generator capable of generating a large quantity of fine air bubbles with few variations in grain size. <P>SOLUTION: The fine air bubble generator, as shown in Fig. 1, is structured so that a plurality of Venturi tubes 3 are mounted on a front chamber 2 with a volume suitable to suppress a flowing velocity of water, each of the Venturi tubes is mounted with a diffuser 4 on outlet side, and the diffuser meets to have a volume suitable to suppress a flowing velocity of water and then meets at a chamber 5. Gathering water flows out from an outlet 6. In this structure, to increase the inner velocity of the Venturi tube against the required amount of water to pass, a plurality of Venturi tubes with fine tube diameters are important to install. By increasing the inner velocity of the Venturi tube, high vacuum occurs and supersaturated air is separated from water to generate fine air bubbles. <P>COPYRIGHT: (C)2011,JPO&INPIT |
