摘要
通过控制锌电积的电流密度按用电峰时段300 A/m2、谷时段600 A/m2及平时段480 A/m2进行长周期锌电积试验,考察了分时供电对锌电积阴极锌质量、电流效率、直流电单耗及电费的影响,并与工业生产实际进行对比分析.结果表明,对于年产12万t锌锭的企业,锌电积生产每年节约电费约2 100万元.
Abstract
The effects of time-sharing power supply on long period zinc electrowinning were investigated, such as, quality of cathode zinc, current efficiency, DC consumption and electric fee. Current density of zinc electrowinning was controlled on 300 A/m2 at peak period, 600 A/m* at valley period and 480 A/m2 at normal period respectively. The comparison of experimental results with actual production shows that a-bout 21 million RMB electricity cost will be saved in zinc electrowinning with 120 kt capacity.
