摘要
铝电解槽的电能消耗量与平均电压和电流效率两个因素有关,降低槽电压或者提高电流效率,可降低铝电解槽直流电耗。通过系统测试系列电解槽电压平衡、能量平衡、电流效率,深入挖掘分析,提出了节能降耗技术措施。通过2台试验槽工业试验表明,试验槽平均电压3.819 V,电流效率92.89%,吨铝直流电耗12251 kWh。与系列电解槽相比,平均电压降低99 mV,电流效率提高1个百分点,吨铝直流电耗降低455 kWh,节能效果显著。
The electrical energy consumption of aluminum electrolysis cells is related to two factors:average voltage and current efficiency.Reducing the cell voltage or improving current efficiency can reduce the DC power consumption of aluminum electrolysis cells.Through systematic test of voltage balance,energy balance and current efficiency of a series of electrolytic cell,and in-depth analysis,the technical measures of energy saving and consumption reduction were put forward.The industrial test of two test tanks shows that the average voltage of the test tank is 3.819 V,the current efficiency is 92.89%,and the DC power consumption per ton of aluminum is 12251 kWh.Compared with the series electrolytic cell,the average voltage is reduced by 99 mV,the current efficiency is increased by 1 percentage point,the DC power consumption per ton of aluminum is reduced by 455 kWh,and the energy saving effect is remarkable.
