| titleOfInvention | A bipolar membrane electrodialysis method for preparing sodium hypochlorite and hydrochloric acid from concentrated seawater |
| abstract | A bipolar membrane electrodialysis method for preparing sodium hypochlorite and hydrochloric acid from concentrated seawater, the bipolar membrane electrodialysis method is carried out in the bipolar membrane electrodialysis device shown in the accompanying drawings; the bipolar membrane electrodialysis method comprises: (1) Pretreatment of the concentrated seawater to reduce the concentration of calcium and magnesium ions in the concentrated seawater to less than 10 ppm; (2) Passing the concentrated seawater after the pretreatment in step (1) into the desalination of the bipolar membrane electrodialysis device In the chamber, chlorine production chamber, cathode chamber and anode chamber, pure water is passed into the concentration chamber; the volume of liquid added to each compartment is the same, and the liquid flow rate of each compartment is kept the same; then the DC power supply is turned on for electrodialysis treatment, and it is observed that The conductivity of the desalination chamber is no longer reduced, which is regarded as the end of the reaction, or the liquid in the desalination chamber is replaced to further concentrate chlorine production; finally, hydrochloric acid is obtained in the concentration chamber, and sodium hypochlorite solution is obtained in the chlorine production chamber, cathode chamber and anode chamber. The present invention avoids direct discharge of concentrated seawater to affect the environment, and obtains significant economic benefits. |
