电解液进液方式对电解铜粉能耗的影响

Effects of electrolyte feeding form on energy consumption of electrolytic copper powder

以研发的新型电解槽为主体,采用不同流量组合进液方式,研究流量和流向等实验参数对电解铜粉槽电压和电耗的影响,总结流量和流向变化对电解过程槽电压和电耗规律,对电解法制备铜粉节能降耗方法进行探索。在Cu^(2+)浓度为10 g·L^(-1),酸度为150 g·L^(-1),电解温度为40℃,电流密度约为1400 A·m^(-2)的情况下实验,结果表明,加入单一侧流后可明显降低电解槽的槽电压和能耗,在流量为9 L·min^(-1)时,分别采用高侧流和低测流的进液方式,可节能12.12%和6.52%;采用双侧侧流的进液方式可很大程度上降低电解槽的槽电压和能耗,在双侧流量均为9 L·min^(-1)时,节能率可达20%以上。

Taking the developed new electrolytic cell as the main body,using the combined liquid inlet mode of different flow rates,this paper studies the effects of experimental parameters such as flow rate and flow direction on the voltage and power consumption of electrolytic copper powder cell,summarizes the laws of the changes of flow rate and flow direction on the voltage and power consumption of electrolytic copper powder cell,and explores the energy-saving and consumption reduction methods of electrolytic copper powder preparation.The results showed that the cell voltage and energy consumption of the electrolytic cell can be significantly reduced by adding a single side flow.When the flow rate is 9,the energy can be saved by 12.12%and 6.52%by using high side flow and low measuring flow respectively;Adopting the liquid inlet mode of bilateral side flow can greatly reduce the cell voltage and energy consumption of the electrolytic cell.When the bilateral flow is 9,the energy saving rate can reach more than 20%.
