报废汽车零部件回收问题的研究
摘要:随着我国汽车工业的迅速发展,汽车广泛进入家庭是必然趋势,汽车保有量的增大,必然会带来回收方面的问题。作好报废汽车的回收、拆解和循环再利用工作,对保护环境、节约能源和经济的可持续发展具有重要的意义。本文研究了国内外报废汽车的拆解现状,对报废汽车的零件重用、材料回收、关键零部件的再制造等进行了价值分析。指出了当前报废汽车拆解工艺上的污染环境、拆解效率低下、回收手段原始等缺陷,提出了一套适合我国当前报废汽车拆解的拆解工艺,该工艺对环保、提高汽车零部件的回收率、拆解自动化等方面有着积极的意义。
总之,汽车零部件的拆卸回收与再生是节约资源,降低成本,实现汽车绿色化设计的重要措施之一,它使汽车产品能够以材料能量或零部件的形式再生与重用,从而使汽车产品处于一个闭环的工业生态系统中,以实现资源的循环利用和环境保护,促使汽车工业可持续发展。

Scrap recycling problem of auto parts
Abstract:With the rapid development of china automobile industry, it is a necessary developing trend that car into family . The increase of car in use must bring the problem of car recovery. It is very important of properly dealing with the End-of-life Vehicles for protecting environment ,saving resource and sustainable development of economy. Both the domestic and the foreign countries current status of handing the End-of-life vehicles have been studied in this paper , an economy model for analyzing ponents' reuse ,recycling and remanufacturing was proposed. In addition ,a set of new disassembling process plan was presented based on climinating of domestic current disassembling process plan
In conclusion ,disassembly and recycling and regeneration of automobile part is one of effective means to saving resources ,reducing costs and realizing the green design of automobile ,It can regenerate and reuse automobile products as material, The technology not only realizes reuse and environmental protection but also can achieve the continued development of automobile industry.
Keywords:End-of-life vehicles,disassembly,recycling and remanufacturing,informat-

上个世纪90年代以来,世界性的环境污染日趋严重,废弃的汽车也成为一大污染源,全世界现有近8亿辆在用汽车,每年大约有5000-6000万辆报废,仅仅停放,就要占用500-600平方公里的土地。而报废汽车当中含有多种重金属、化学液体、所料等物质,不当单位拆解也会赵成环境污染。汽车生产要使用数百种材料,消耗一亿多吨的钢铁、上千万吨的塑料,以及大量的橡胶、玻璃、纺织品、铝、铜、铅、铬、各种化工产品等等,消耗大量的资源,其中
