摘要
根据废DZM铅蓄电池铅膏中各组分的物料特性,对废铅膏原料进行154,77,54μm孔径逐级漂洗筛分,随后对各级筛上物进行电解分离,分别收集电解完成后的上层纤维和下层的PbSO_(4)和金属铅混合物,对各组分进行质量分析、SEM形貌分析以及XRD检测。结果表明:筛上物主要成分是PbSO_(4)和少量Pb,最终筛下物主要成分是PbO_(2)和PbSO_(4)。经过54μm孔径筛分实验后,分离出的隔膜纤维为废铅膏总量的9.45%,证明利用逐级漂洗筛分和电解分离方法能有效分离出废铅膏中的隔膜纤维。
According to the material characteristics of each component in waste lead paste,the raw materials of waste lead paste were rinsed and screened for 154μm aperture,77μm aperture and 54μm aperture step by step.Afterwards,electrolytic separation experiments were carried out on the materials above each grade of sieve,PbSO_(4),and metal lead mixture in the lower fiber and the upper fiber were collected respectively.Through scanning electron microscope(SEM)morphology analysis and X-ray diffraction(XRD)detection,the results showed that the diaphragm fiber in waste lead paste could be separated effectively by step rinse screening and electrolytic separation.The main lead compounds in the material above the sieve were PbSO_(4)and a small amount of Pb,and the main components in the material below the sieve were PbO_(2)and PbSO_(4).After 54μm aperture sieving experiment,the separated diaphragm fibers reached 9.45%(by mass ratio)of the total waste lead paste.
