摘要： A microbubble generation device comprises a liquid inlet (101), a gas inlet (104), a bubble flow outlet (103), and a gas-liquid mixing chamber (102). An air-permeable hole having an angle structure is provided at a gas-liquid interface of the gas-liquid mixing chamber (102), and a pointed end of the angle structure of the air-permeable hole points to a liquid flow direction. The bubbles generated by the device are extremely small in diameter, prolonging a duration the bubbles stay in the liquid phase, and enhancing gas-liquid mass transfer efficiency.
