一、前言在湿法炼铜中,从铜的浸出液中采用不溶阳极电积铜的总能耗包括电耗和蒸汽消耗两部分。在铜电解沉积过程中,电解液一般不采用单独的加热措施,而是依靠电能的热使电解液温度逐槽升高。当室温在15℃以上时,各槽电解液平均温度可达40～45℃。电积所消耗的蒸汽不多,仅用于电铜和种板的煮洗。而吨铜的直流电耗一般为1800～2500度,个别厂甚至高达3000度。电耗占铜电积总能耗的绝大部分,所以铜电积工序节能的关键和潜力是节约电能。
I. Introduction In wet-process copper smelting, the total energy consumption of copper from the leaching solution of copper, which is insoluble in the anode, includes the two parts of electricity consumption and steam consumption. In the electrolytic deposition of copper, the electrolyte generally does not use a separate heating measure, but relies on the heat of the electric energy to increase the temperature of the electrolyte by the bath. When the room temperature is above 15 ℃, the average temperature of electrolyte in each bath can reach 40 ~ 45 ℃. Electric consumption of steam consumption is small, only for copper and seed plate cooking wash. The tons of copper DC power consumption is generally 1800 ~ 2500 degrees, even up to 3000 individual plants. Electricity consumption accounts for the vast majority of the total energy consumption of copper products, so the key and potential of energy conservation in copper electrowinning processes is to save energy.
