Simulation Of Electric Field And Flow Field For The New 10KA Rare Earth Electrolysis Cell

As far as the future of rare earth metallurgical industry, the conserving energy and consumption reduction is the primary problem to be solved. But, for the present rare earth electrolysis cell, the heat loss of electrolyte is greatly. Thereupon, to probe a new groove structure of rare earth electrolysis cell, with the aim of adapting the massive industrial production, it seems to be particularly necessity. And the article, on the basis of summarizing the former experience, by means of the understanding of the groove structure of rare earth electrolytic cell, draw on the experience of the groove structure of natrium electrolytic cell, and consult the works of Zhang Xiao-lian et al: Neodymium Electrolysis in Low Current Densities, and then design a new groove of the all buried imitation from natrium electrolytic cell to carry on the simulation of the distance between the anode and the cathode, and the high.There is the complex physical field in rare earth electrolysis cell, while the electric field is the foundation of other physical fields, and temperature field and flow field are important factors to decide the production efficiency and energy consumption.. How to plan the reasonable electric field, flow field and temperature field determine the rationality concerning the design of electrolyzer. Therefore, the study of electric field, flow field and temperature field is very significant. This paper make full use of simulation software-ANSYS to simulate the electric field as to the new rare earth electrolytic cell of imitation from natrium electrolytic cell for the first time, and simulates the distance of between the anode and the cathode(the chief respect of anode), the distance of between the cathode and the anode (the chief respect of cathode), the high of the cathode and the thickness of the anode. The analysis and the determination is the basis of the voltage of electrolyzer and electric field force, and identify the optimum value from simulation under the variation of different parameters. And, at the same time, it fully utilize the simulation software-FLUENT to simulate the flow field as to the new rare earth electrolytic cell of imitation from natrium electrolytic cell for the first time, and simulate the distance of between the anode and the cathode(the chief respect of anode), the distance of between the cathode and the anode(the chief respect of cathode), the high of the cathode and the thickness of the anode. By means of the simulation of the electric field and the flow field, it is certain that the optimum value of the distance(the chief respect of anode) is 0.09m, the distance( the chief respect of cathode) is 0.085m, the high of the cathode is 0.573m, and the thickness of the anode is 0.07m. Taking the topic for exploratory and basic subject, its significance lies in not only the theoretical exploration but also the improvement and innovation to the new groove structure of rare earth electrolysis cell, and provide the theoretical foundation for actual production.
