摘要
研究镍电解槽电流分布可为判断电解是否正常提供有力依据。传统人工检测镍电解槽电流方法耗时耗力、判断短路/断路效果不佳,且镍电解车间存在温度较高、环境恶劣、实际测量困难等问题。针对上述问题以某镍厂镍电解槽阴极导电棒为研究对象,利用多物理场仿真软件COMSOL Multiphysics4.3a中的传热模块,建立合理的物理模型并进行有限元的计算分析。通过数值仿真和现场测试相结合的方法,研究在镍电解中通电稳定情况下导电棒温度与电流分布之间的关系。通过图像处理方法分析现场拍摄采集的图像,得到与温度成一定线性关系的像素值的分布图,并与仿真图像作对比。仿真结果可为镍电解电流分布和准确判断极板短路/断路提供模型参考和理论依据。
The cathode electrode rod of Ni - electrolyzer from a certain industry is investigated with establishing Heat Transfer Module by applying multi - physics - based simulation software, COMSOL Multiphysics 4. 3a. More detailed description of how to create a correct and reasonable physical model and Finite Element Calculation are also adopted for the analysis of the model. Both numerical simulation and field testing are used for studying the relation- ship between current distribution and temperature of electrode rod of Ni - electrolysis when other condition parameters of model are stable. The simulation and field testing results verify the effectiveness of the proposed method.
