摘要
运用数值模拟软件COMSOL建立了不同极间距下3 k A Nd电解槽的物理模型,针对包头稀土研究院的3 k A稀土电解槽进行了电-热场的耦合模拟。模拟结果验证了耦合的合理性,并发现槽电压随极间距的增大而增大,电解槽的整体温度随极间距的增大而升高。结合实际生产经验,认为极间距在75 mm时整个电解过程相对稳定,可以达到电解中槽体电压、温度分布等方面的要求。该研究结果为稀土电解槽进一步的结构优化提供了参考。
The numerical simulation software COMSOL was used to establish the physical model of the 3 k A neodymium electrolytic cell with different polar distance,and the coupling simulation of the electric-thermal field was carried out for the 3 k A rare earth electrolytic cell of the Baotou Rare Earth Institute. The simulation results verified the rationality of the coupling,and found that the voltage and the overall temperature of the electrolytic cell increase with the increasing of the polar distance. Combined with the actual production experience,the whole process of electrolysis was relatively stable when the polar distance is 75 mm,and the requirements of voltage and temperature in the electrolytic cell can be achieved. The results of this study provided the reference for further optimization of structure of the rare earth electrolytic cell.
