    • PROBLEM TO BE SOLVED: To provide a loop flow type bubble generating nozzle which generates microbubbles, has a structure simpler than a conventional one, and can be miniaturized.
      SOLUTION: The loop flow type bubble generating nozzle 10 comprises a cylindrical member 1 having a gas inflow hole 1a in its side to communicate with the outside and inside for allowing gas to flow in, a disk member 2 installed so as to close one end of the cylindrical member 1 and having a spout hole 2a in the center, and a disk member 3 installed so as to close the middle of the inside of the cylindrical member 1 and having a liquid supply hole 3a in the center for supplying a pressurized liquid. A gas-liquid loop flow type agitating and mixing chamber 4 is an almost cylindrical space formed by being surrounded by the cylindrical member 1, the disk member 2, and the disk member 3.

    • PROBLEM TO BE SOLVED: To make a loop current type bubble generation nozzle capable of generating bubbles with an average diameter smaller than 100 μm, particularly, microbubbles with an average diameter around 20 μm and having a more simple and compact configuration than a conventional one. SOLUTION: A liquid is supplied via a liquid supply hole 3a from one end side and a gas is supplied via a gas supply chamber 4 from the other end side to a loop current type gas-liquid stirring and mixing chamber 5. Herein, while being swirled on a center axis of the liquid supply hole 3a in the gas supply chamber 4, the gas flowing in through a gas flow-in hole 2a is supplied toward one end side of the loop current type gas-liquid stirring and mixing chamber 5 from the entire or a part of the circumference to the loop current type gas-liquid stirring and mixing chamber 5. In the loop current type gas-liquid stirring and mixing chamber 5, the liquid and the gas are stirred and mixed by the loop-like current to be a mixed fluid and jetted through a jetting hole 1a.
