Title:
MICROBUBBLE GENERATION METHOD AND MICROBUBBLE GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/207651
Kind Code:
A1
Abstract:
[Problem] To provide a microbubble generation method and a microbubble generation device with which it is possible to generate microbubbles with a nano-order diameter in a liquid efficiently. [Solution] A microbubble generation device comprising: a liquid storage bath 10 for storing a liquid; a liquid delivery unit 20 which suctions up and delivers the liquid stored in the liquid storage bath 10; an air bubble supply unit 30 which supplies air bubbles to the liquid being delivered by the liquid delivery unit 20; and a liquid storage bath 40 in which the liquid to which air bubbles have been supplied by the air bubble supply unit 30 is stored. Pure water is introduced into the liquid storage bath 10, a liquid delivery pump 24 in the liquid delivery unit 20 is activated, and, while the pure water in the liquid storage bath 10 is being delivered to an air bubble supply unit 22, air is released from an A-type gas release head 31 in the air bubble supply unit 22, whereby air bubbles are supplied to the pure water as the pure water passes through the air bubble supply unit 22 in a turbulent state. The pure water including the air bubbles is delivered to the liquid storage bath 40 and stored therein. In 1 ml of the pure water stored in the liquid storage bath 40, 1.4 × 108 microbubbles with an average air bubble diameter of 98 nm existed.
