Problems solved by technology

[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

Abstract

The invention discloses an aluminum electrolysis leak tank detection method based on a leak tank monitoring device, which belongs to the field of aluminum electrolysis tank monitoring. The invention dynamically monitors the collected temperature according to the collected temperature value of the aluminum electrolysis tank and the temperature change trend of the aluminum electrolysis tank. Compensation enables the system to accurately predict the amount of temperature adjustment to effectively monitor the temperature of the aluminum electrolysis process, and can more accurately and effectively monitor the leakage of each point of the electrolytic cell in real time, ensuring the quality of the aluminum electrolysis work. At the same time, the adaptability of the temperature monitoring method in different aluminum electrolysis environments is guaranteed because the influence of interference data is greatly eliminated. And by judging whether the time when the compensated temperature value is greater than or equal to the temperature setting value reaches the threshold value, the occurrence of the leakage tank can be effectively avoided.
