<p>PROBLEM TO BE SOLVED: To provide a nano-bubble manufacturing apparatus capable of acquiring high concentration nano-bubbles with a fine and uniform particle size.SOLUTION: A nano-bubble manufacturing apparatus includes: a liquid tank 2 in which a bubble-containing liquid introduction port 21a is arranged in the upper part, and a bubble-containing liquid lead-out port 21b is arranged at the bottom; a microbubble-containing liquid supply part 3 for supplying microbubble-containing liquid that contains microbubbles to the bubble-containing liquid introduction port 21a of the liquid tank 2; an ultrasonic collapsing part 4 for irradiating an ultrasonic wave to the inside of the liquid tank 2 so as to form an ultrasonic collapse place where the collapse of microbubbles by the ultrasonic wave occurs intensively and nano-bubbles are generated at a place where the microbubble-containing liquid supplied in the liquid bank 2 through the bubble-containing liquid introduction port 21a flows downward; and a nano-bubble-containing liquid lead-out part 5 for leading out the nano-bubble-containing liquid that contains the nano-bubbles generated by the ultrasonic collapsing part 4 to the outside of the liquid tank 2 through the bubble-containing liquid lead-out port 21b.</p> |
