中文摘要:
      以6kA镨钕电解槽为研究对象,运用多物理场有限元分析软件COMSOL,对不同阴极直径下的6kA镨钕电解槽电解过程进行电热场耦合数值模拟,分析阴极直径对槽内电热场的影响。结果表明,随着阴极直径的改变,电解槽内的电场与温度场均发生变化并且相互影响,结合实际生产经验和模拟仿真研究,认为阴极直径为80mm时,能够为6kA镨钕电解槽产生足够电解反应发生的焦耳热,达到良好的电解效率。根据研究结论能够为实际优化此镨钕电解槽结构参数提供参考。
英文摘要:
      Study on 6kA Pr-Nd electrolyzer, the multi-physics finite element analysis software COMSOL was used to simulate the Thermo-Electric field coupling of the electrolytic cell process under different cathode diameters,analysis of the influence of cathode diameter on the Thermo-Electric field in the cell .The results show that the electric field and temperature field in the electrolysis cell change and influence each other with the change of cathode diameter. Combined with the actual production experience and the research in this paper, it is considered that when the cathode diameter is 80mm, sufficient electrolytic reaction can be generated for the electrolyzer. Joule heat, achieving good electrolysis efficiency. According to the conclusions of this paper, it can provide a reference for the actual optimization of the structural parameters of this 6kA Pr-Nd electrolyzer.
