摘　　要：研究了可一步实现废镀锡电线电缆资源化的新方法。废镀锡电线电缆在真空条件下热解液化的同时,利用离心分离的方法将熔化的锡分离出来。实验后得到铜线、含锡碳渣、热解油、热解气。热解油可作为化工原料或进一步加工成燃料,少量不可凝的热解气体经碱液吸收后收集,以便循环利用。Vacuum pyrolysis-centrifugation coupling technology was investigated for separating and recovering components from waste tin-plated wire and cable in this study.Waste tin-plated wire and cable was pyrolysed under vacuum condition,and simultaneously the molten tin was separated and recovered in the pyrolysis process by the centrifugal method.After experiment,copper wire,pyrolysis oil and gas,and pyrolysis residue（including both charcoal and tin） were obtained.The pyrolysis oil can be used for fuel or chemical feedstock for further processing,and the pyrolysis gas can be collected and recycled.
