　　Brief Introduction of Vacuum Distillation Recovery Technology for Waste Ni-Cd Batteries

　　Nickel-cadmium batteries have the advantages of cheap price, high capacity, good charge and discharge performance, large instantaneous current and good safety performance. According to statistics, in 2000, the sales volume of nickel-cadmium batteries in the world was about 1.4 billion, and the sales volume was 1.4 billion US dollars. And in the next few years, nickel-cadmium batteries will still occupy an important share of the market.

　　China is a big country in the production and use of nickel-cadmium batteries. In 2000, the sales volume of nickel-cadmium batteries increased by 30%. Such a large number of nickel-cadmium batteries has brought convenience to people, but it has also caused serious environmental problems. If it can be recycled, it will not only avoid environmental pollution, but also save limited resources.

　　In this paper, a vacuum-assisted recovery experimental device for nickel-cadmium batteries was developed, and the combination of vacuum distillation and regional smelting selective recovery technology was used to recycle waste nickel-cadmium batteries.

　　in conclusion

　　1) Vacuum distillation can be used to separate the various components of the nickel-cadmium battery, and the metal cadmium with a purity greater than 99% can be obtained.

　　2) The effective distillation temperature of cadmium should be selected between 573 ~ 1173K.

　　3) When the system pressure is 10pa, the content of cadmium in the distillation residue decreases significantly when the temperature rises between 773-1173K; the distillation temperature is 1173K, and the pressure decreases between 80-20pa, the content of cadmium in the distillation residue is downward trend.
