In the prior art, judge whether that the method for needing to increase pH value of the electrolyte to stablize soda acid water mainly has following two
Kind:
(1) by reading pH value to determine whether increasing electrolyte.The method is theoretically most straightforward approach, i.e. PH
The dispensing of electrolyte it has been worth to be increased by low, the high dispensing for just reducing electrolyte of pH value.But in practical operation, examined since PH is counted
The delay hysteresis quality of survey, the effect of real-time control are simultaneously not so good as people's will, for example, continuing when getting low pH value, actual capabilities have been connect
The electrolysis water for having received many low pH values also needs electrolysis a period of time that could improve pH value when being further added by electrolyte, in water route.
(2) by reading TDS value to determine whether increasing electrolyte.How much the TDS value of electrolysis water is one by one with electrolyte
Relevant, the more then TDS values of electrolyte are big, therefore certain TDS value can be set according to experiment experience value, when TDS value height then subtracts
Few electrolyte is launched, and TDS value is low then to increase electrolyte increase, to realize that the pH value of electrolysis soda acid water controls.But TDS value
Reflection to PH is nonlinear, even if TDS is very high, but the TDS value of electrolysis water and the non-linear relation of pH value will also result in
The lag of pH value stability contorting makes TDS change to another value from a value for example, increasing or decreasing electrolyte, and pH value becomes
Change relatively much slower, the asynchronous or electrolysis water electrolyte content both resulted in this way is not enough or electrolysis water electrolyte
Content is higher, causes waste to reduce electrolytic efficiency etc., therefore the pH value stability of PH does not comply with one's wishes yet.
Although controlling precision, spirit from the foregoing, it will be observed that above two method can tentatively produce certain soda acid water
