Background technology
The reaction feed liquid often need change acidity in chemical industry, the light industry production, adopt usually to add mineral acid, alkali neutral method, though simple and easy to do, produce a large amount of inorganic salt behind the acid-base neutralisation and enter waste water, bring problem for the processing of subsequent production waste water.
Summary of the invention
The purpose of this invention is to provide a kind of is power with the electricity, changes the method for reaction feed liquid potential of hydrogen in chemical industry, the light industry production.
Principle of the invention figure as shown in Figure 1.
A kind of control method of potential of hydrogen of feed liquid, it is to be respectively equipped with anode and negative electrode on the both sides of electrolyzer, with cationic exchange membrane or anion-exchange membrane electrolyzer is separated into three zones: the anolyte compartment, feed liquid chamber and cathode compartment, when feed liquid need be turned down the pH value, adopt cationic exchange membrane, the anolyte compartment puts into sulphuric acid soln, the feed liquid that needs processing is put in the feed liquid chamber, cathode compartment is put into sodium hydroxide solution, between anode and negative electrode, add volts DS, then the proton that produces in the anolyte compartment passes cationic exchange membrane and enters the feed liquid chamber, and simultaneously original positively charged ion passes cationic exchange membrane and enters cathode compartment and be recovered in the feed liquid chamber, and the pH of the feed liquid in the feed liquid chamber reduces; When feed liquid needs heightening pH value, adopt anion-exchange membrane, anolyte compartment and cathode compartment are all put into sodium hydroxide solution, the feed liquid that needs processing is put in the feed liquid chamber, add volts DS between anode and negative electrode, then the hydroxide ion that produces in the cathode compartment passes anion-exchange membrane and enters the feed liquid chamber, and simultaneously original negatively charged ion passes anion-exchange membrane and enters the anolyte compartment and be recovered in the feed liquid chamber, the pH of the feed liquid in the feed liquid chamber raises, and the potential of hydrogen of feed liquid is conditioned.
The control method of above-mentioned potential of hydrogen, described electrode materials can be titanium plating rare metal electrode, stainless steel or graphite.
The control method of above-mentioned potential of hydrogen, described feed liquid chamber can be furnished with recycle pump, and the feed liquid in the feed liquid chamber is constantly circulated.
The control method of above-mentioned potential of hydrogen, described anolyte compartment is or/and cathode compartment can be furnished with recycle pump, and sulphuric acid soln or sodium hydroxide solution constantly circulate.
The control method of potential of hydrogen of the present invention, consumption acids or alkali are conditioned the acidity or alkalinity of feed liquid, do not increase the salt concn in the feed liquid, and the salt concn in the last waste water is lower, makes the processing of subsequent production waste water more or less freely.
