Title:
METHOD AND APPARATUS FOR PRODUCING FINE BUBBLE
Document Type and Number:
Japanese Patent JP2014198327
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable efficient production of a high-concentration nano-bubble liquid making a variation in bubble diameter small, in a method for producing nano-bubbles by crushing microbubbles by ultrasonic irradiation.SOLUTION: A liquid transfer passage is installed within a cistern. A microbubble-containing liquid flows through the liquid transfer passage; ultrasonic waves are applied into the cistern; standing waves of the ultrasonic waves are generated within the cistern; and microbubbles are crushed near a loop position of sound pressure of the standing waves of the ultrasonic waves to produce a nano-bubble-containing liquid.
