“双端节能”铝电解槽的热电仿真计算及模拟研究

Thermoelectric emulation and simulation study of"Double End Energy Saving"aluminum reduction cells

本文采用ANSYS软件对400 kA铝电解槽内部热场及炉帮形状进行研究,通过对侧部安装微通道热管集热器的试验槽仿真模拟,确定了集热功率与电解槽侧壁温度及槽内炉帮厚度之间的关系,进而实现了准确解析槽内热场的目标。这对于进一步探究能量流对电解槽内热特性的影响以及研究铝电解的“双端节能”具有十分重要的理论和实际意义。

In this paper,ANSYS software is used to study the internal thermal field and the ledge profile of 400 kA aluminum reduction cells.Through the simulation of the test cell with the micro-channel heat pipe collector installed on the side,the relationship is determined between the heat collection power and the temperature of the side wall of the aluminum reduction cell as well as the ledge thickness inside the cell,thus accurately analyzing the thermal field inside the cell.It is of great theoretical and practical significance to further explore the influence of energy flow on the thermal characteristics of aluminum reduction cells and to study the"Double End Energy Saving"of aluminum electrolysis.
