NEUTRALIZER AND HOT WATER DEVICE HAVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a neutralizer which properly prevents strong alkaline drain water from being discharged in the case of using a basic neutralization agent as neutralization agent, with a simple structure, requiring no complex control.;SOLUTION: A neutralizer A1 has a neutralization tank 10 including: a bypass communication part 11 which is arranged upstream of a termination part 10e in the drain water flow direction for flowing the drain water to a discharge port 13; and a pH-responding type valve V1 which allows for opening/closing operation in response to the pH of the drain water in the neutralization tank 10. The opening/closing operation of the ph-responding type valve V1 allows a first state for not passing the drain water through the bypass communication part 11 to be set when the drain water in the neutralization tank 10 does not achieve the predetermined pH, while allowing a second state for passing the drain water through the bypass communication part 11 to be set when the drain water achieves the predetermined pH.;COPYRIGHT: (C)2014,JPO&INPIT
