This post was last edited by “Back to Cambridge” on February 27, 2016, at 11:23. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their fundamental knowledge in chemical engineering. Subsequently, series such as “Principles of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: Analyze the reasons for alkali leakage in electrolyzers Answer: The sealing rings of the electrolyzer lose their flexibility and age over time as a result of prolonged operation. In particular, the gaskets located in the protruding parts of the cell, which serve as air channels and liquid channels, fail more quickly due to large temperature fluctuations. In some electrolyzers, uneven circulation of the alkaline solution leads to changes in the temperature of the cell, resulting in premature local leakage of alkali.

The sealing rings of the electrolyzer lose their toughness and age after long-term operation; in particular, the gaskets located in the protruding parts of the cell, which serve as air channels and liquid channels, deteriorate due to large temperature fluctuations, resulting in alkali leakage

In particular, the gaskets located in the protruding parts of the cell, which serve as air channels and liquid channels, fail more quickly due to large temperature fluctuations. In some electrolyzers, uneven circulation of the alkaline solution leads to temperature variations within the cell, resulting in premature local leakage of the alkali.

1. Aging of the gasket； 2. Poor plate sealing ； 3. Uneven heating of the tank body ； 4. No maintenance was carried out after running for a period of time.
1. Reasons for material leakage during feeding: Excessively high feeding pressure； The partition in the material box is not sealed properly ； The backflow air pressure of the electrolyzer discharger is high. 2. Reasons for material leakage during the purification process: Domestic alumina has a low density; as it falls, it is disturbed by the gases ejected from the flame ports and becomes airborne, being drawn into the tank by the suction force generated by the exhaust fan. It then falls onto the surface of the electrolyzer tank due to the vibrations that occur during shell breaking. 3. Leakage of material from the flame hole: The flame hole is blocked, causing all or part of the alumina material to fall onto the shell surface instead of entering the electrolyzer completely. 4. Material leakage is caused by a fault in the feeder; the reason is poor sealing of the feeder’s cylinder.
