  • Patent number: 11110414
    Abstract: A bubble generation device includes: a metallic narrow tube (10) through which water passes; and a pump that pressure-feeds the water containing a gas component into the metallic narrow tube (10). A drawer (11) in which a path through which the water passes is narrower than the front and the rear thereof in the flow direction of the water is disposed on the inside of the metallic narrow tube (10). The drawer (11) has the rectangular cross section orthogonal to the flow direction. The gas component contained in the water is dissolved in the water by pressure-feeding the water to the drawer (11), bubbles are evolved due to a decrease in pressure in the drawer (11), turbulent flow is generated in the water in the drawer (11) to crush bubbles in the water by the shearing force thereof, and bubbles are crushed by a shock wave caused by transonic flow occurring in the water that has exited from the drawer (11).
