在镁电解过程中,提高电解液液位可以降低电解镁槽的槽电压和能耗。在本文中,采用全电池的三维模型来研究镁电解池中电池电压和电解质水平之间的关系。首先讨论了电解液深度为1.25~1.45μm时镁电解槽不同电流强度下的电阻电压。此外,改变阳极的尺寸以及阳极和阴极的位置以研究电池中电阻电压的趋势。整合电解液各部分的能量消耗,进一步了解电解液中的能量分布,探索电解液的哪一部分对电池电压的贡献最大。通过分析电池电压、能量分布和热平衡的组成部分,可以获得电解液液位与能耗之间关系的解释。
In the process of magnesium electrolysis, increasing the level of electrolyte can reduce the cell voltage and energy consumption in an electrolysis magnesium cell. In this paper, a three‐dimensional model of a full cell was implemented to study the relationship between the cell voltage and electrolyte level in a magnesium electrolysis cell. Firstly, the resistance voltage of difference current intensity in magnesium electrolysis cells were discussed with the electrolyte depth from 1.25 to 1.45 m. Moreover, the size of anodes and positions of anodes and cathodes were changed to investigate the trend of resistance voltage in the cell. The energy consumption in each part of the electrolyte was integrated to further understand the energy distribution in the electrolyte to explore which part of the electrolyte has the greatest contribution to the cell voltage. Through analyzing components of the cell voltage, energy distribution, and thermal balance, the explanation of the relationship between electrolyte level and energy consumption can be obtained.
