Problems solved by technology

However, during the incineration process of phenolic resin, it will produce toxic and harmful organic gases, such as dioxin, etc.
Therefore, the incineration method to treat phenolic resin-based copper-clad laminates not only causes waste of resources, but also causes harm to the environment, and the exhaust gas treatment cost of the whole process is relatively high.

Abstract

The invention provides a treatment system and recycling method for phenolic resin based copper clad laminate. The treatment system comprises a first-stage crusher, a second-stage crusher, a grinder, acyclone separator and a separation device sequentially connected, the gas outlet of the cyclone separator is further connected with a dust removal device, the solid outlet of the cyclone separator isconnected with the separation device, the separation device comprises a vibration sieve and an electrostatic separator, an intermediate product collection container is arranged on the electrostatic separator, and the discharging port of the intermediate product collection container is connected with the feeding port of the second-stage crusher. The treatment system can recycle the phenolic resinbased copper clad laminate by adopting a multi-level physical crushing and separation technology, after passing through the dust removal device, the tail gas is purified, the toxic and harmful gas generated in the process of burning the copper clad laminate is avoided, the effective separation of the metal copper and the phenolic resin is achieved, the resource utilization of the phenolic resin powder can be achieved, and the recycling method has high separation recovery efficiency and low treatment costs.

Description

technical field [0001] The invention belongs to a method and a device for recycling electronic waste, in particular to a processing system and a recycling method for a phenolic resin-based copper-clad laminate. Background technique [0002] With the acceleration of the replacement of electronic products, more and more waste circuit boards, including copper clad laminates, are produced. The substrates of copper clad laminates are polycarbonate, phenolic resin, epoxy resin and other types. Among them, phenolic resin is a kind of thermosetting material, which generally cannot be recycled by melting method. The previous treatment process of phenolic resin-based copper clad laminates is mainly through incineration, mainly recovering the copper of copper clad laminates, and phenolic resin is consumed by incineration. However, during the incineration process of phenolic resin, toxic and harmful organic gases, such as dioxin, will be produced. Therefore, incineration treatment of ...
