Problems solved by technology

However, the current external natural circulation ionic membrane electrolysis device is mainly a unipolar ionic membrane electrolysis device that combines electrolysis units with parallel power supply. To meet the necessary conditions for uniform current distribution, more precious metal materials are required, and the manufacturing cost is high and the structure is complicated. , covers a large area
[0004] The above-mentioned bipolar or monopolar electrolysis devices, regardless of the circulation mode, have defects such as being unfavorable to stable operation in terms of specific structural design.
In addition, in the overall design, reasonable consideration of measures to prevent electrochemical corrosion is often ignored

Description

Technical field [0001] The invention relates to a natural circulation type ion membrane electrolysis device, which belongs to the field of electrolysis equipment in the chlor-alkali industry in the chemical industry. Background technique [0002] At present, in the chlor-alkali industry, ion-exchange membrane electrolyzers are more and more favored by users for their high production efficiency and good product quality. However, the existing forced-circulation ion-exchange membrane electrolyzers have disadvantages such as high pressure, large pressure difference, and complicated operation and operation processes, and are gradually being replaced by natural circulation methods. The existing bipolar natural circulation ion-exchange membrane electrolysis device is mainly an internal natural circulation method. Its working method is to directly inject the raw material medium into the electrolysis reaction chamber at a certain flow rate and flow rate. The temperature, concentration, an...
