Emergency handling of leaks at the cathode or anode of a chlorine engineering ion-exchange membrane cell during operation
Thread Content
Experts, leaks occur during the operation of the electrolyzer tank. For minor leaks, trying to tighten the connections might help; in case of major leaks, it’s necessary to shut down the system immediately. What precautions should be taken during this shutdown process? For example: various flow rates, the speed at which current is reduced, and other such issues.
It leaked severely; pressing the emergency stop button stopped it right away.
For minor leaks in chlorine plant electrolyzers, it is not recommended to tighten the rods; you should examine the location of the leak as well as the operating conditions. For example, in the case of leakage at the sealing surface of the electrolyzer, when the current is low and the temperature of the cell is low, you should use a ruler to measure each tie rod; if the force required is 80 N, there’s no need to tighten the rods any further. Simply increasing the temperature of the cell will resolve the leakage issue after some time. Even when the leakage is severe, the decision should be based on the actual situation on site; if it has not reached the point where it connects with the ground, parking according to the plan is still necessary. Of course, in the event of a large-scale leak, it is necessary to shut down the system immediately to prevent more serious accidents from occurring.
