摘要
通过对废弃空调换热器中可回收材料的深入研究,提出了一种对空调换热器中铜材和铝材进行有效回收和分离的方法。该方法利用铜、铝材料之间机械性能的差异,采用对辊装置对换热器进行辊轧,以提高铜、铝材料之间的可分离性。对辊轧后的换热器进行破碎、分离和分类即可回收高品位的铜和铝。该处理工艺环保性能好,易于实现自动化操作,适合空调换热器的大批量回收。
After detailed study of recoverable materials in heat exchangers included in a post-use air conditioner,an efficient separating method has been presented to recycle copper and aluminum,which are component materials of the heat exchangers.In this separating method,the heat exchangers are treated by a rolling machine to enhance the separability through utilizing the difference of mechanical characteristics between copper and aluminum,and then the products are crushed,separated and classified to recover high quality copper and aluminum.This technology has advantage of environmental protection,is easy to realize automation and is suitable for batch recycling of heat exchangers in air-conditioner.
