High concentration dissolved water generator and a high concentration dissolved water generation system

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for generating high-concentration dissolved water capable of obtaining the high-concentration dissolved water by securing sufficient contact for dissolving gas in raw water and also suppressing enlargement of the apparatus, and a system for generating the high-concentration dissolved water.;SOLUTION: The apparatus for generating the high-concentration dissolved water 60 includes: a cylindrical gas-liquid contact tank 63 from which dissolved water generated by bringing fine air bubbles into contact with the raw water introduced from an inlet 631a is removed from an outlet 634a; an air bubble generator 64 for generating the fine air bubbles into the gas-liquid contact tank 63; a dissolved water pipe 651 to be a circulation passage one end of which is connected to the top of the gas-liquid contact tank 63, another end of which is connected to the bottom and to which the dissolved water in the gas-liquid contact tank 63 flows; and a circulating pump 652 provided on the dissolved water pipe 651 and circulating the dissolved water in the gas-liquid contact tank. The raw water brought into contact with the fine air bubbles from the air bubble generator 64 in the gas-liquid contact tank 63 is made into the high-concentration dissolved water by orbiting around the dissolved water pipe 651 with the circulating pump 652 to repeat circulation.;COPYRIGHT: (C)2011,JPO&INPIT
