MICRO-NANOBUBBLE BATHTUB WATER PRODUCTION METHOD AND MICRO-NANOBUBBLE BATHTUB

摘要

PROBLEM TO BE SOLVED: To provide a micro-nanobubble bathtub water production method and a micro-nanobubble bathtub economically producing a great volume of micro-nanobubbles with diversified sizes. SOLUTION: In this micro-nanobubble bathtub 1, two types of first and second micro-nanobubble generators (a submerged pump type micro-nanobubble generator 2 and a rotational flow type micro-nanobubble generator 10) generate 2 types of micro-nanobubbles with different size distributions in the upper part and lower part of a micro-nanobubble generation part 34 so as to produce great volume of bathtub water including the micro-nanobubbles with wide size distributions. Part of the micro-nanobubble containing water generated in the lower part is made to flow in the upper-part first micro-nanobubble generator (the rotational flow type micro-nanobubble generator 10) so that the rotational flow type micro-nanobubble generator 10 can generate micro-nanobubbles of smaller size.
