The invention discloses an aluminum electrolysis tank leakage detection method based on a tank leakage monitoring device, and belongs to the field of aluminum electrolysis tank leakage monitoring. The leakage conditions at each point of an electrolytic tank body are monitored through the temperature at each point of the tank body and real-time change, so that the method is accurate and effective; and simultaneously, the service life of the tank leakage monitoring device can be prolonged, and the accuracy and stability of the aluminum electrolysis tank leakage detection method are ensured.

Description

technical field [0001] The invention belongs to the field of aluminum electrolytic cell monitoring, in particular to a method for detecting aluminum electrolytic leaky tanks based on a leaky tank monitoring device. Background technique [0002] In today's aluminum electrolysis industry, metal aluminum is obtained by electrolysis of alumina. When aluminum is electrolyzed, alumina is in the electrolytic cell, and the temperature in the electrolytic cell is very high, reaching thousands of degrees. Since the electrolytic cell is composed of a cathode and a refractory brick After a period of time, it will cause leakage in some places of the electrolytic cell. If there is a leakage tank, it will cause the electrolytic cell to not work normally and must be repaired. On the one hand, the electrolytic cell cannot perform electrolytic aluminum work, and the output will drop. On the other hand, due to the maintenance of the electrolytic cell, the economic loss will be relatively large...

[0002] In today's aluminum electrolysis industry, metal aluminum is obtained by electrolysis of alumina. When aluminum is electrolyzed, alumina is in the electrolytic cell, and the temperature in the electrolytic cell is very high, reaching thousands of degrees. Since the electrolytic cell is composed of a cathode and a refractory brick After a period of time, it will cause leakage in some places of the electrolytic cell

If there is a leakage tank, it will cause the electrolytic cell to not work normally and must be repaired. On the one hand, the electrolytic cell cannot perform electrolytic aluminum work, and the output will drop. On the other hand, due to the maintenance of the electrolytic cell, the economic loss will be relatively large; It may also lead to casualties of workers operating on site

Therefore, it is very important to be able to predict the leakage of the electrolytic cell online in real time in the electrolysis workshop. Since the temperature in the cell is as high as thousands of degrees during the electrolysis of aluminum, it is impossible to observe the leakage in real time from the inside of the electrolytic cell. Currently, there is no such An accurate and effective detection method for leakage of aluminum electrolytic cell
