A reclamation system is used for mercury-zinc and mercury-cadmium battery disassembly. The mercury-zinc/mercury-cadmium reclamation system has a cooling station, a cracking station, a disassembly station and a shredder station. The cooling station freezes the batteries to facilitate cracking of the housing by the cracking station. The cracked batteries are then disassembled and the battery cells are shredded. The shredded cells are placed in the retort oven, for recovery of mercury. In an alternative embodiment, the reclamation system is used for silver-zinc battery disassembly. The silver-zinc reclamation system has a staging and draining station, cracking station, and disassembly station. At the staging and draining station, wet batteries are separated out and drained. The batteries are then cracked, disassembled and washed. The washed cells are placed in the retort oven, for recovery of mercury.
A battery reclamation system for recycling a battery having a case that encloses a cell, comprising a freezing chamber for freezing the battery, a cracking station for cracking the battery case and removing the battery cell, a shredder for shredding the battery cell, and a retort oven for retorting the shredded battery cell.
A battery reclamation system for recycling a battery having a case that encloses a cell, comprising a disassembly station for removing the case and separating silver contained within the battery, and a retort oven for retorting the battery cell.
A method for recycling a battery having a casing enclosing a cell, comprising freezing the battery casing, cracking the frozen casing, removing the cell from the cracked casing, shredding the cell, and retorting the shredded cell.
A method for recycling a battery containing silver and having a casing enclosing a cell, the method comprising removing the casing, separating the silver, and retorting the cell.
A retort system for removing an element from a material, the system comprising:
A retort system for removing an element from a material, the system comprising an oven for heating the material so that the element enters a vapor form, and a first quench tank receiving the element in vapor form from said oven, said first quench tank containing water and passing the vapor form of the element from the oven into the water to cool the element to a liquid form, the retort system further comprising cooling coils located in said first quench tank for cooling the water contained in said first quench tank.
