| Abstract: |
| Research status of pyrolysis technology in treatment of waste circuit boards and structure of common pyrolysis equipment, working principle, their advantages and disadvantages were summarized. Progress of atmospheric pressure inert gas pyrolysis technology, vacuum pyrolysis technology, molten salt pyrolysis technology and catalytic pyrolysis technology in pyrolysis of waste circuit boards were discussed. Steel belt furnace, multiple hearth furnace and rotary kiln pyrolysis commonly used in industrial production were mainly introduced. The problems to be solved and future research directions of waste circuit board pyrolysis technology and pyrolysis device were discussed. |
