Definitions

  • the above method separates and recycles the components of the waste circuit board, and the recycling process has the disadvantages of high energy consumption and easy pollution environment.
  • the recycling of waste circuit boards should fully consider the harmless and efficient recovery of metals and organic materials.
  • the early recovery of solder can create favorable conditions for the efficient separation of other metals. Therefore, the existing technology needs to be further improved to improve recovery efficiency and recovery.
  • High-temperature cracking of waste circuits and waste glass steel by microwave technology can eliminate environmental pollution caused by coal incineration.
  • the cracking requirement can be achieved by using microwave high-frequency radiation to bring the temperature in the furnace within several tens of seconds.
  • the volatile matter distillation range is low, and the dry distillation organic matter is mostly aromatic hydrocarbon organic matter with recovery value.

Abstract

L'invention porte sur un procédé pour la récupération de ressources de valeur à partir de GFRP (plastique renforcée par des fibres de verre) de rebut et de cartes de circuits imprimés de rebut, comprenant les étapes suivantes : (1) le thermo-craquage avec des micro-ondes consistant à mettre le GFRP de rebut et les cartes de circuits imprimés de rebut dans un four à microondes à haute fréquence, mettre en marche le four à micro-ondes à haute fréquence et chauffer le matériau à une température élevée de 500-600°C sous l'effet des micro-ondes pour décomposer et craquer les matières polymères de masse moléculaire élevée thermo-durcies pour obtenir un gaz thermo-craqué et un résidu solide ; (2) la condensation consistant à collecter le gaz thermo-craqué dans le four provenant de l'étape (1) et le condenser pour obtenir une matière organique mélangée à base d'hydrocarbures aromatiques ; (3) la fusion du résidu consistant à collecter le résidu solide provenant de l'étape (1), le faire fondre à une température élevée dans un four de fusion et le séparer pour obtenir des métaux non ferreux et un résidu carboné. Le procédé a un processus de traitement simple, ne provoque pas de pollution, a un faible coût et un rendement de récupération élevé.
