Abstract

The invention relates to a discarded electronic product treatment method and device. A plurality of discarded electronic products to be treated are conveyed to a vacuum cracking device, and plastic materials in the discarded electronic products are subjected to low-temperature vacuum cracking to generate gaseous oil gas, so that the production of toxic gas and gas explosion phenomena are avoided,the cost is lowered during use, and safety and environment protection are achieved. Then, metal materials are heated and molten into liquid metal in a high-temperature vacuum cracking manner, and thegaseous oil gas and the liquid metal are respectively treated by a filtering device and a separation device to obtain liquid oil products, liquid hydrogen chloride, gaseous auxiliary fuel and the like, so that the practicability of the discarded electronic products is improved greatly. The discarded electronic product treatment method and device have the advantages of safety in use, environmentalfriendliness and full recovery.

Description

Technical field[0001]The present invention relates to a method and device for processing waste electronic products, in particular to a method and device for processing waste electronic products that can be used safely, comply with environmental protection and fully recycled.Background technique[0002]Due to the rapid changes in science and technology and the rapid changes in society, the use of electronic products is closely related to people’s lives. However, because of the widespread and large-scale use of electronic products, it is also relative to the waste parts, circuit boards or There is an increasing trend of circuit accessories year by year. The current treatment method for electronic product waste is mainly to burn the electronic product waste in the furnace at high temperature (about 1500℃). Because the waste is made of plastic or metal at the same time, the plastic material will produce toxic gases such as dioxin during the high-temperature combustion process, and it must...
