摘　　要：针对传统铜电解槽的铜钉现象,基于有限元分析提出了结构改进策略。首先,以铜电解槽电流密度为研究对象,从机理上分析了铜电解槽电流密度分布特征;其次,利用COMSOL有限元仿真软件对铜电解过程中电解槽电流密度的强度大小进行了仿真,得到了原始槽内阳极、阴极、电解质的电场分布变化规律;然后,分析了阴极板上部产生“铜钉”现象的原因;最后,通过去除槽壁的涡流区域,提出了槽结构优化方案。仿真结果验证了所提方案的正确性,改进后的槽结构有效减少了“铜钉”现象。Aiming at the copper nail phenomenon of traditional copper electrolytic cell,a structural improvement strategy is proposed based on finite element analysis.Firstly,taking the current density of copper electrolytic cell as the research object,the distribution characteristics of current density of copper electrolytic cell are analyzed from the mechanism;Secondly,COMSOL finite element simulation software is used to simulate the current density of the electrolytic cell in the process of copper electrolysis,and the variation law of the electric field distribution of the anode,cathode and electrolyte in the original cell is obtained.Then,the causes of“copper nails”on the upper part of the cathode plate are analyzed.Finally,by removing the vortex region of the groove wall,the optimization scheme of the groove structure is proposed.The simulation results verify the correctness of the proposed scheme,and the improved slot structure effectively reduces the“copper nail”phenomenon.
