Title:
FINE BUBBLE GENERATION DEVICE AND BUBBLE DIAMETER CONTROL METHOD
Document Type and Number:
Japanese Patent JP2015080756
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fine bubble generation device capable of freely reducing and increasing the size of bubbles in gas-dissolved water.SOLUTION: There fine bubble generation device 1 capable of controlling a bubble diameter is provided that includes a gas-liquid supply part 3 which supplies gas-liquid mixed water, a fine bubble generation part 5 which generates fine bubble-containing water from supplied gas-liquid mixed water and a concentration changing part 6 which is arranged downstream from the fine bubble generation part and freely changes dissolved gas concentration or saturated dissolved gas concentration in the fine bubble -containing water. The fine bubble generation part dissolves gas in the gas-liquid mixed water, thereafter, foams the fine gas-containing water and, thereby, can generate fine bubbles, or pulverizes air bubbles in the supplied gas-liquid mixed water and, thereby, can generates the fine bubbles, and the concentration changing part 6 can control any of the following items: (1) extension of bubble diameter according to rise of dissolved gas concentration; (2) contraction of bubble diameter according to fall of dissolved gas concentration; (3) contraction of bubble diameter according to rise of saturated dissolved gas concentration; and (4) extension of gas diameter according to decrease in saturated dissolved gas concentration.
