针对6 k A新型Ce电解槽结构,采用数值模拟软件建立该电解槽的电场模型。模拟了在阴、阳极高度相差一定的情况下,同时改变阴、阳极的插入深度从而分析电解槽内电场的变化情况。研究表明:随着阴、阳极插入深度的不断变化,电解槽内部电流密度和槽电压也随之发生变化,阴、阳极插入深度逐渐增加,槽电压逐渐降低,电解槽底部的电压差增加,但电流密度值却逐渐减小,产生热量也会降低,阴、阳极插入深度减少,槽电压越来越高,电解过程中由电流产生的热量就会逐渐增加,电流效率却逐渐降低,因此通过模拟后发现最佳的阴极插入深度约为0.290 m,阳极高度约为0.250 m。通过对电场的模拟,为Ce电解槽开发设计具有很重要的意义。
For the 6 kA new Ce cell structure, the electric field model of the cell was established by numerical simulation software. Simulated in the cathode and anode height difference between a certain case, while changing the anode and cathode insertion depth in order to analyze changes in the electrolysis cell electric field. The results show that the current density and the cell voltage in the cell change with the change of the anodic and cathodic insertion depths. The insertion depth of the anodic and cathodic electrodes increases gradually, the cell voltage decreases and the voltage difference at the bottom of the cell increases, The current density is gradually reduced, the heat generation is also reduced, the insertion depth of the anode and the cathode is reduced, and the cell voltage is higher and higher. The heat generated by the current in the electrolysis process gradually increases and the current efficiency decreases gradually. Therefore, by simulating The best cathodic insertion depth was found to be about 0.290 m and the anode height was about 0.250 m. Through the simulation of the electric field, it is very important to develop the design for Ce cell.
