される。In the microbubble generator of the present invention, the pressurized water from the pressurized water supply means and the pressurized air from the pressurized gas supply means are both sent to the gas-liquid mixing means.
The gas-liquid mixing means mixes the pressurized water and the pressurized gas to generate a bubble-water mixed fluid in which bubbles having a small diameter are mixed in water. When the air supply port that ejects the pressurized air is arranged in the casing toward the downstream side, bubbles are formed by the ejection of the pressurized air into the running water, and the bubbles are mixed in the running water to mix the bubble water mixed fluid. Is generated and the bubbly water mixed fluid is taken out from the outlet. If the air supply port is displaced from the center line of the outlet, the generated bubbles will not be promptly taken out from the outlet, and the retention time of the bubbles inside the casing will be long, and the bubbles will be dispersed in the running water. The degree is increased. When a transfer pump such as a gear pump is connected to the gas-liquid mixing means, the bubble-water mixed fluid is sucked by the transfer pump and further pressurized, but at that time, the bubble-water mixed fluid is agitated to mix the bubble-water mixed fluid. The bubbles in the fluid are divided and the bubbles are subdivided, the uniformity of the bubbles distribution in the bubble-water mixed fluid is enhanced, and the bubbles are transferred to a desired location by the fluid transfer pipe.
