在现代湿法炼锌中,由于硫酸锌溶液进行电解沉积过程中在直流电的作用下产生电热效应,使电解液温度逐渐升高,当液温超过所规定温度(一般应小于41℃)时,不仅浪费电能影响产品质量,面且还会使槽上酸雾增大,污染环境,恶化劳动条件。因此,在锌电解生产过程中,要不断地对电解液进行冷 In modern zinc hydrometallurgy, the electrolyte temperature is gradually increased due to the electrothermal effect caused by the direct current during the electrolytic deposition of the zinc sulfate solution. When the liquid temperature exceeds the specified temperature (generally, it should be less than 41 ° C.) Not only was the waste of electricity affecting the quality of the product, it also caused the acid mist in the tank to increase, polluting the environment and deteriorating working conditions. Therefore, in the electrolytic production of zinc, the electrolyte should be constantly cold
