工业铝电解槽是一种在高温和高腐蚀性条件下运行的电化学反应器。然而,这些条件限制了关键控制参数的测量,使铝电解槽的控制成为行业难题。由于铝电解控制系统具有重要的经济影响,因此对铝电解槽的控制算法、控制系统和信息系统进行了大量的研究。本文首先综述了控制系统的发展,然后重点介绍了2000年以来在氧化铝浓度控制、温度控制和电解质分子比控制、故障诊断、槽况预测和控制系统扩展等方面取得的进展。在此基础上,提出了智能铝电解厂的概念。介绍了该系统的框架结构、关键问题及目前的进展。最后,讨论了几个未来的发展方向。
The industrial aluminum reduction cell is an electrochemistry reactor that operates under high temperatures and highly corrosive conditions. However, these conditions have restricted the measurement of key control parameters, making the control of aluminum reduction cells a difficult problem in the industry. Because aluminum electrolysis control systems have a significant economic influence, substantial research has been conducted on control algorithms, control systems and information systems for aluminum reduction cells. This article first summarizes the development of control systems and then focuses on the progress made since 2000, including alumina concentration control, temperature control and electrolyte molecular ratio control, fault diagnosis, cell condition prediction and control system expansion. Based on these studies, the concept of a smart aluminum electrolysis plant is proposed. The frame construction, key problems and current progress are introduced. Finally, several future directions are discussed.
