Description

Technical Field

[0001] The invention relates to the technical field of nonferrous metal metallurgy, and in particular to an online monitoring system and method for alumina concentration in aluminum electrolysis production. Background Art

[0002] In the aluminum electrolysis production process, the concentration of alumina in the electrolyte has an important impact on current efficiency, energy consumption and product quality. Traditional methods for detecting alumina concentration mostly use laboratory analysis, such as titration or spectral analysis. Although these methods can provide relatively accurate results, they have obvious shortcomings: first, these methods are time-consuming and cannot meet the needs of real-time monitoring; second, the operation is complicated and requires professional technicians to operate, which increases labor costs; third, these methods cannot achieve continuous monitoring, and it is difficult to detect and correct abnormal conditions in the production process in a timely manner, which may lead to unstable product quality and low production efficiency.

[0003] Although the existing online monitoring technology can partially solve the above problems, it still has some defects. For example, some online monitoring systems rely on a single parameter (such as conductivity) to infer the concentration of alumina, which is often not accurate enough in complex and changeable electrolysis environments. In addition, most of the existing monitoring systems lack intelligent data analysis capabilities and cannot automatically adjust the electrolysis process parameters according to real-time data, resulting in limited optimization of the production process. At the same time, many systems do not have remote monitoring functions, and users need to operate and manage them on site, which increases labor intensity and management difficulty. Therefore, there is an urgent need for an online monitoring system that can monitor the concentration of alumina in real time and accurately, and has intelligent control and remote management functions, in order to improve the efficiency and quality of aluminum electrolysis production.
