A kind of online self-cleaning sodium hypochlorite synthesis system

Abstract

The present invention is an online self-cleaning sodium hypochlorite synthesis system, the counter electrode plate is arranged at intervals from the anode plate and the cathode plate; Unlike the cathode plates interconnected at the same time, when the counter electrode plate is connected with the anode plate or the cathode plate, the polarization scaling on the plate is removed. In the online self-cleaning sodium hypochlorite synthesis system provided by the present invention, the variable frequency power supply is used as the power supply, and the remote terminal communicates with the general controller in two directions. The general controller controls the variable frequency power supply to output different voltages and frequencies to adjust the electromagnetic intensity and frequency and change the electrolysis efficiency. The counter electrode is regularly connected to the anode plate or cathode plate, and works in the reverse working mode, and the electromagnetic valve at the water outlet is controlled by the master controller to close and the electromagnetic valve at the sewage outlet is opened to eliminate the polarization scaling effect of the original counter electrode. Realize online automatic cleaning and descaling, energy saving and cost reduction, cleaning time length, high electrolysis efficiency and long service life.

Description

technical field [0001] The invention belongs to the technical field of sodium hypochlorite preparation, and in particular relates to an online self-cleaning sodium hypochlorite synthesis system. Background technique [0002] Most of the working principle of sodium hypochlorite generator is to use DC power supply to prepare sodium hypochlorite disinfectant through the electrochemical reaction of electrode plates placed in salt water or sea water. The positive electrode and negative electrode in the electrode plate work continuously for a long time After that, magnesium and calcium ions are easy to deposit and scale on the surface of the electrode plate, which affects the electrolysis efficiency, and even blocks the inside of the electrode and affects the use in severe cases. At present, sodium hypochlorite generators are cleaned by adding an acid solution to the electrolytic cell. The concentration of the acid solution needs to be adjusted and cannot be too high or too low. T...

Problems solved by technology

[0002] Most of the working principle of sodium hypochlorite generator is to use DC power supply to prepare sodium hypochlorite disinfectant through the electrochemical reaction of electrode plates placed in salt water or sea water. The positive electrode and negative electrode in the electrode plate work continuously for a long time Finally, magnesium, calcium ions, etc. are easy to deposit and scale on the surface of the electrode plate, affecting the electrolysis efficiency, and even clogging the inside of the electrode and affecting the use

At present, sodium hypochlorite generators are cleaned by adding acid solution to the electrolytic tank. The concentration of the acid solution needs to be adjusted and cannot be too high or too low. The work is cumbersome, the cleaning time is long and the cleaning effect is not good.
