Cyclic utilization device and method for discarded aluminum plastic resources

Abstract

The invention belongs to the technical field of aluminum plastic separation cyclic utilization and discloses a cyclic utilization device and a method for discarded aluminum plastic resources. The method comprises the following steps of firstly, classifying and sorting; secondly, smashing; thirdly, washing materials; fourthly, soaking and separating, wherein sodium hydroxide and an unsaturated sodium aluminate solution are added to a soaking and separating device so that soaking can be conducted, an aluminum foil layer reacts with sodium hydroxide, and plastic is separated out; or hydrochloricacid is added to the soaking and separating device so that reaction can conducted, aluminum chloride is prepared, and the plastic is separated; fifthly, washing the plastic; and sixthly, separating the plastic. According to the cyclic utilization method for the discarded aluminum plastic resources, through an inorganic solution soaking method and airtight type harmless treatment, automated cyclictreatment is carried out on waste water and exhaust gas generated in the production process; the discarded aluminum plastic resources are changed into agents which can be used for treating industrialwaste water and exhaust gas pollution; a large quantity of high-quality plastic is also acquired; zero emission of discarded aluminum plastic resource cyclic treatment is achieved; and the purposes oftreating waste with waste and changing waste into wealth are achieved.

Description

technical field [0001] The invention belongs to the technical field of aluminum-plastic separation and recycling, and in particular relates to a device and method for recycling waste aluminum-plastic resources. Background technique [0002] Waste aluminum-plastic resources are also known as organic polymer materials. Because of their good thermoplastic properties, solid and durable properties, and excellent light blocking and thermal insulation properties, they are widely used in industrial production and people's lives. According to relevant statistics, plastic wastes in the world exceed more than 30 million tons not only pollutes the environment, but also loses a lot of aluminum and plastic resources, and also causes certain difficulties in garbage disposal. In recent years, the waste aluminum and plastic resources are also called "white pollution". Therefore, the waste aluminum and plastic resources are recycled. Utilization becomes very important. [0003] At present, t...

Problems solved by technology

Due to the lack of various equipment and improper technical treatment, the technology is backward and the environment is polluted, which hinders the deep development of waste aluminum-plastic resources and leads to low resource utilization efficiency, which also reflects the promotion of the concept of recycling waste aluminum-plastic resources from the side. There is a serious shortage, and there is an urgent need for a resource recycling technology with low energy consumption, high recycling rate and no pollution
