NANOBUBBLE GENERATION METHOD AND NANOBUBBLE GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a nanobubble generation method where pressure is regulated by changing the diameter of a diameter reduction part, so as to easily and securely generate nanobubbles, and to provide a nanobubble generator with a simple structure.;SOLUTION: Piping 7 for introducing a pressurized liquid into which a pressurized liquid obtained by dissolving a gas under pressure is introduced and piping 9 for generating nanobubbles are connected via a flow rate regulation valve 10, and the diameter of the discharge flow of a diameter reduction part 12 provided at the inside of the piping for generating nanobubbles is set in such a manner that the ratio between the pressure (P1) at the inside of the piping for introducing a pressurized liquid and the pressure (P2) at the inside of the piping for generating nanobubbles, (P2/P1) becomes a ratio for generating nanobubbles.;COPYRIGHT: (C)2010,JPO&INPIT
