Abstract
A green resource-based method of thermal mass synergy in waste Integrated circuit board mainly includes carbonization cracking system, crushing and separation system, gasification cracking system and heat value utilization and comprehensive recovery system. Compared with existing techniques, carbonization cracking system can realize the dry distillation cracking of organic matter in waste integrated circuit board which converts carbon, hydrogen and other elements into fuel carbonized cracking gas and cracking oil, the heat from the combustion of the carbonization cracking gas of the invention provides the energy needed for the carbonization cracking to realize self-heating carbonization cracking. Carbonization cracking products are cracked and separated to solve the problems such as hard to break and organic coating metal caused by direct crushing and separation of traditional circuit boards which Improves crushing and separation effect; gasification cracking system achieves the comprehensive utilization of carbon, the gasified cracking gas can be used as a heat source for subsequent valuable metal recovery to further improve the utilization rate of calorific value. The invention h…
