Aluminum electrolysis leaking tank detection method based on wireless leaking tank monitoring device

Abstract

The invention discloses an aluminum electrolysis leaking tank detection method based on a leaking tank monitoring device and belongs to the field of aluminum electrolysis tank monitoring. According to the method, collected temperature is dynamically compensated for according to the collected aluminum electrolysis tank temperature value and the aluminum electrolysis tank temperature change tendency so that a system can accurately prejudge the temperature adjustment amount, the temperature in the aluminum electrolysis process is effectively monitored, temperature measurement accuracy and stability are improved, leakage conditions of all points of an aluminum electrolysis tank body can be monitored in real time more accurately and effectively, and the quality of aluminum electrolysis work is guaranteed. Meanwhile, influences of interference data are greatly eliminated, and thus adaptability of the temperature monitoring method in different aluminum electrolysis environments is guaranteed. At the same time, the leakage conditions of the points of the aluminum electrolysis tank body can be monitored in real time according to the temperatures of the points of the electrolysis tank body and the change in unit time, and accuracy and effectiveness of detection of leakage of the aluminum electrolysis tank are further improved.

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
