铝电解生产添加锂、镁盐复含剂在60千安以上系列应用,节能效果显著。但在30千安系列铝电解槽中应用该技术锂盐单耗高达6.405公斤/吨铝。为此,将锂、镁盐掺水制成复合剂进行试验,结果锂盐单耗降到2.582公斤/吨铝,电流效率提高2.36％,吨铝增产26.26公斤,降低电耗1079千瓦小时/吨铝,并减少氟化物排放量43.36％,取得了较好的经济效益和社会效益。
Aluminum Electrolytic production Add lithium, magnesium salt compound containing more than 60 KA series applications, energy-saving effect is remarkable. But in the 30 kA series of aluminum electrolytic cell technology, the unit consumption of lithium salt up to 6.405 kg / t aluminum. To this end, the lithium, magnesium salt water mixture made of the test, the results of lithium salt consumption dropped to 2.582 kg / ton of aluminum, current efficiency increased 2.36%, 26.26 kilograms of aluminum per ton, reducing power consumption 1079 kilowatt hours / ton Aluminum, and reduce fluoride emissions 43.36%, and achieved good economic and social benefits.
