The invention is suitable for the technical field of scraped car recycling, and provides a scraped car disassembling and recycling process which comprises the following steps: (1) checking and registering; (2) disassembling pretreatment; (3) disassembling: disassembling the scraped car parts, and selecting waste plastic electroplated parts; (4) cleaning the waste plastic electroplated part in the step (3); (5) the cleaned waste plastic electroplated part is put into leaching equipment to be leached; (6) treating the chemical leaching solution to obtain a nickel-copper mixed solution, and extracting the nickel-copper mixed solution; (7) carrying out back extraction on an organic phase obtained after extraction by adopting sulfuric acid as a back extraction agent; by cleaning the waste plastic electroplated part, particles on the surface of the waste plastic electroplated part can be prevented from being mixed into a leaching solution, impurities in the liquid can be further removed by treating the chemical leaching solution, and double filtration can be carried out, so that the purity of a metal ion solution is prevented from being influenced.
本发明适用于报废汽车回收技术领域,提供了一种报废汽车拆解回收利用工艺,包括以下步骤:(1)检查登记;(2)拆解预处理;(3)拆解:将报废汽车零部件拆解,选出废塑料电镀件;(4)清洗步骤(3)中的所述废塑料电镀件;(5)将清洗后的所述废塑料电镀件放入浸出设备中浸出;(6)化学浸出液经过处理后,得到镍铜混合液,所述镍铜混合液进行萃取;(7)萃取后得到的有机相采用硫酸作为反萃取剂进行反萃取;本发明通过对废塑料电镀件进行清洗,可避免废塑料电镀件表面颗粒混入浸出液中,而通过对化学浸出液进行处理,可进一步的去除液体中的杂质,本发明能够进行双重过滤,避免影响金属离子溶液的纯度。
