摘要
在实验室条件下,对镍镉电池的真空蒸馏基本规律进行了探索.分析了温度、压力和时间等工艺因素对镍镉分离效果的影响,并对镍镉电池的真空蒸馏机理进行了研究,为废旧镍铜电池资源化提供了理论依据和实验数据.
Recovery of Ni-Cd batteries was studied by a self-designed vacuum-aided recycling system under laboratory conditions. The impacts of temperature, pressure and time were studied respectively. The mechanism of vacuum thermal recycling was also discussed. The results show that, at constant pressure, the increase of temperature can improve the separation efficiency of cadmium. When the temperature is 1173 K, the cadmium can evaporate completely from the residue during 3 h at 10 Pa. The reduction of pressure in a certain range is effective to separate cadmium by vacuum distillation. Distillation time is a very important factor affecting separation of cadmium.
