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 w...

Abstract

The invention discloses an aluminum electrolysis cell leakage detecting method based on a cell leakage monitoring device, and belongs to the field of aluminum electrolysis cell monitoring. The method dynamically compensates acquired temperature according to acquired aluminum electrolysis cell temperature values and aluminum electrolysis cell temperature variation trends, so that a system can accurately prejudge a temperature regulating quantity to effectively monitor the temperature in the aluminum electrolysis process, the leakage condition in each point of a cell body of the electrolysis cell can be more accurately and effectively monitored in real time, and the aluminum electrolysis quality is guaranteed; and meanwhile, as the influence of interference data is greatly eliminated, the adaptability of the temperature monitoring method in different aluminum electrolysis environments is guaranteed. The cell leakage condition can be effectively prevented through judging whether the time of the compensated temperature value not smaller than a set temperature value reaches a threshold value or not.

Description

technical field [0001] The invention belongs to the field of aluminum electrolytic cell monitoring, and in particular relates to a method for monitoring and alarming an aluminum electrolytic cell leak. 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; It may als...
