Description

Technical Field

[0001] The utility model relates to the field of ion membrane caustic soda, in particular to an ion membrane caustic soda concentration regulating device. Background Art

[0002] Ion membrane caustic soda is made by electrolyzing brine with ion exchange membrane. The main principle is that the cation exchange membrane used has special selective permeability, which only allows cations to pass through and prevents anions and gases from passing through, that is, only allows H+ and Na+ to pass through, while Cl-, OH- and the bipolar products H2 and Cl2 cannot pass through. Therefore, it prevents the anode product Cl2 and the cathode product H2 from mixing and causing the risk of explosion, and also prevents Cl2 from reacting with another cathode product NaOH to generate NaClO, which affects the purity of the caustic soda.

[0003] At present, in order to ensure the alkali concentration during the ion-exchange membrane caustic soda production process, a concentration regulating device is required. Although the current concentration regulating device can adjust the concentration during use, during use, since the alkali is generally mixed with pure water in a certain proportion before detection, it is difficult to detect in real time during the mixing process of the alkali and pure water, so that the regulation efficiency of the alkali concentration is poor. Therefore, those skilled in the art provide an ion-exchange membrane caustic soda concentration regulating device to solve the problems raised in the above background technology.
