摘　　要：以国内某冶炼厂铜电解槽为原型,基于计算流体力学,利用Fluent软件对铜电解槽内流场进行数值模拟,并对槽内不同特征截面上电解液流动状态进行分析。结果表明:模拟计算得到的槽面电解液流动状况与现场观测结果基本吻合,从而验证模拟结果的有效性;采用该"下进上出"电解液循环方式对槽内特征区域电解液的有效流量进行计算,发现电解液有效利用率仅15.41%左右。针对该问题分析成因后提出了具体建议和措施,为进一步优化电解槽结构、改进操作工艺和扩大产能提供理论依据。With the copper electrolytic cell of domestic copper smelter as the prototype based on computational fluid dynamics, the flow fields in the copper electrolytic cell were simulated with Fluent software, and the flow condition of electrolyte on different characteristics cross-section inner cell were analyzed. The results show that the electrolyte flow conditions from simulation basically agrees well with the local observation results, then, the effectiveness of simulation results is validated. The electrolyte effective flux in characteristic region using the ＂Bottom inlet to top outlet＂ circulation way of electrolyte were calculated, and the effective utilization of the electrolyte is only about 15.41%. After analyzing of the causes for the problem, the specific suggestions and measures were proposed, and the theoretical basis to optimize the cell structure, improve operation process and expand capacity was put forward.
