PROCESS FOR THE RECYCLING OF WASTE BATTERIES AND WASTE PRINTED CIRCUIT BOARDS IN MOLTEN SALTS OR MOLTEN METALS

摘要

Disclosed is a system and method for the recycling of waste composite feed materials such as printed circuit boards (PCBs), batteries, catalysts, plastic, plastic composites such as food packaging materials, for example Tetra Pak®, mattresses, compact disks (CDs, DVDs), automobile shredder residue (ASR), electric cable wastes, liquid display panels, mobile phones of various sizes or combinations of the above using a new pyrolysis system and method.

主权项

1. A system of recycling of waste composite feed materials such as printed circuit boards (PCBs), batteries, mobile phones and the like, the system comprising:
means for charging said feed material from said charging vessel (1, 30) into separation/pyrolysis chamber (8) comprising of a separation/pyrolysis liquid (7); means for allowing the heavy and light solid products associated with said feed material to separate within said separation/pyrolysis liquid (7); means for removing the product vapours and said light solid products via vapour/top dross removal line (23) or extractor (22) or both from the surface of said separation/pyrolysis liquid (7); means for removing said heavy solid products from the bottom or somewhere between the liquid surface of said separation/pyrolysis liquid (7) and the bottom of separation/pyrolysis liquid (7) with solids removal device (15, 16, 17) or alternatively by a drain (20, 21); and means for removing said light solid products via top dross removal device (32) from the surface of said separation/pyrolysis liquid (7).
