Abstract

The invention relates to an ion membrane electrolytic cell. The ion membrane electrolytic cell comprises a cell rack, wherein a plurality of electrolysis unit cell groups (8) are arranged on the cellrack, and the electrolysis unit cell groups (8) have the characteristics that two ends of each electrolysis unit cell group (8) are locked separately through copper row end plates; the copper row endplates are copper row end plates which are fixed on a fixing base or mobile copper row end plates which are fixed on a push rod base, different number of electrolysis unit cell groups (8) and copper row end plates for locking a plurality of electrolysis unit cell groups (8) are selected according to the capacity requirement, and the copper row end plates are connected with a power source. The ionmembrane electrolytic cell has the advantages of good running stability, free assembly and allocation according to the capacity requirement, low electric loss, high production efficiency and high productivity.

Description

technical field [0001] The invention relates to an ion membrane electrolyzer. Background technique [0002] The ion-exchange membrane electrolyzer is a special equipment developed with the application of the ion-exchange membrane in the production of caustic soda. Its basic function is to install an ion-selective exchange membrane between the anode and the cathode. The anode chamber is fed with refined light brine, the cathode chamber is fed with pure water or low-concentration lye, the electrolytic cell is energized to generate electrolytic reaction, chlorine gas is generated in the anode chamber, hydrogen gas is generated in the cathode chamber, and sodium ions (Na+) pass through under the push of the electric field. Through the ion membrane from the anode side to the cathode side, it combines with the hydroxide ion (OH-) of the cathode to generate caustic soda (NaOH). Therefore, since the electrolytic cell was developed, people have carried out research and improvement, ...
