ABSTRACT:
Pyrolysis system and method wherein used batteries other than lead-acid batteries for reclamation and recovery of the constituents therein or environmentally safe disposal are placed in rail carts and moved on rails through an entry zone into a central heating zone of a pyrolysis chamber maintained under a negative pressure and then into an exit zone. A series of rail carts containing the batteries are sequentially transferred, one rail cart at a time, into the entry zone where the pressure is equalized with the central heating zone and the rail cart is transferred into the central heating zone, then the entry zone is returned to atmospheric pressure and another rail cart is moved into the entry zone and the procedure continued until the central heating zone is filled to capacity with rail carts containing the batteries, thereafter the entry zone and exit zone are equalized with the pressure in the central heating zone and a rail cart is transferred from the central heating zone to the exit zone while another rail cart is transferred into the central heating zone. Next the pressure in the entry zone and the exit zone are returned to atmospheric pressure and a rail cart is moved into the entry zone while the rail cart in the exit zone is moved out of the exit zone. The pyrolysis chamber is maintained under a negative pressure to recover the volatilized constituents of the batteries, while the solid constituents of the batteries after pyrolysis remain in the rail carts and are transferred to other processing.
