着重介绍了高纯金属锂工业试验流程、真空蒸馏法提纯锂的原理和连续式锂真空蒸馏炉的特点，并根据工业试验结果讨论了锂的蒸发速度和设备产能、工业试验产品高纯锂的质量以及金属锂回收率等问题。试验结果表明，设备能耗低，７５０℃时蒸馏锂纯度９９９％以上，产能达１５ｔ／ａ。
The process of high purity lithium metal industry test, the principle of vacuum distillation and the characteristics of continuous lithium vacuum distillation furnace are introduced emphatically. According to the results of industrial experiments, the evaporation rate of lithium and equipment capacity are discussed. The industrial test products of high purity lithium Quality and metal lithium recovery and other issues. The test results show that the energy consumption of the equipment is low, the purity of distilled lithium is above 99.9% at 750 ℃, and the production capacity reaches 15t / a.
