Medium sodium hypochlorite generator

1,Principle

Salt water is electrolyzed by direct current through the anode and cathode to produce chlorine on the anode surface, generate sodium hydroxide and hydrogen on the cathode surface, and then react with sodium hypochlorite required by the production system.

The reaction equation is as follows:

4.3,Electrode structure of patented technology

Electrode plate: plate electrode. The anode and cathode base materials of the electrode are all made of pure titanium TA1 material. In the electrolysis process, the cathode is protected, while the anode is lost, so the anode surface must be protected by coating. The anode surface of jsshg brand generator electrode is coated with ruthenium and iridium oxide with particle fineness of 20 nm, which is treated by nanotechnology. The coating is divided into more than 18 times, and the coating thickness is 20 microns, which can ensure the long-term Stable service life.

4.4,Fully transparent electrolytic cell

The following figure:

Our electrolyzer is the only fully transparent design in China, including flanges. When dilute brine is electrolyzed, the electrolytic state is clear at a glance. For electrolysis, the most important thing to pay attention to is whether the electrolytic cell is scaling and whether the electrode works in a safe state. The fully transparent electrolytic cell can visually see the actual situation, so as to better protect the electrolytic cell. The electrolyzer is equipped with liquid level protection, low temperature protection, high temperature protection, low current protection, ultra-high current protection, low voltage protection and ultra-high voltage protection. Once there is an abnormality, the system will send an alarm signal and stop working.

4.5,Energy saving electrolytic power supply

The following figure:

Sodium hypochlorite generator uses high-frequency constant current electronic switching power supply as the electrolytic power supply. Due to the use of high-frequency rectification technology, the AC / DC conversion efficiency reaches more than 95%, the calorific value is very low, the operation is stable, and the volume is small, which is more than 20% higher than the electrical conversion efficiency of ordinary silicon rectifier (sodium hypochlorite generator GB 12176-90 requires current efficiency ≥ 72%).
