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,可使6kA镨钕电解槽产生足够电解反应发生的焦耳热,电解效率良好。
Taking the 6 kA Pr-Nd electrolyzer as the research object,the multi-physics finite element analysis software COMSOL was used to simulate the electrotherma field coupling of the 6 kA Pr-Nd electrolyzer under different cathode diameters.The results show that with the change of the cathode diameter,the electric field and temperature field in the electrolyzer both change and affect each other.Based on the actual production experience and the simulation study,it is considered that when the cathode diameter is 80 mm,sufficient electrolytic reaction can be generated for the electrolyzer.The research results can provide a reference for the practical optimization of the structural parameters of the 6 kA Pr-Nd electrolyzer.
