MICROBUBBLE GENERATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a microbubble generating apparatus stably feeding to bathing water white turbid gas-liquid dissolved fluid containing a large amount of microbubbles of appropriate sizes, by stabilizing the sizes of the microbubbles jetted out of a discharge port. SOLUTION: The microbubble generating apparatus 100 is provided with a microbubble generating means 30 forming microbubbles by releasing the pressure of the gas-liquid dissolved fluid with gas pressurized and dissolved in liquid, and the discharge port 3 jetting out the microbubbles. The microbubble generating means 30 has a gas dissolving part 8 forming the gas-liquid dissolved fluid containing microbubbles by dissolving gas into liquid, a Venturi tube 12 serving as a microbubble crushing part crushing microbubbles formed in the gas dissolving part 8 to form further smaller microbubbles, and a pressure reducing part 13 lowering the pressure proceeding toward the discharge port 3 between the Venturi tube 12 and discharge port 3.
