PROCESS FOR CRUSHING AND SEPARATING OF WASTE MAINTENANCE-FREE LEAD-ACID STORAGE BATTERY

摘要

Disclosed is a process for crushing and separating of a waste maintenance-free lead-acid storage battery. The crushing and separating process comprises separation and recovery of an electrolyte, separation and recovery of a plastic shell, separation and recovery of a lead grid, separation and recovery of a laminar film and a rubber valve, and separation and recovery of a lead slime. In the present invention, various materials of the waste maintenance-free lead-acid storage battery are separated such that the various materials such as the electrolyte, plastic shell, lead grid, laminar film, rubber valve, lead slime, etc. are respectively recovered and the separated and recovered various materials have high purities and are easily recycled; and in the present invention, a physical method is used to mechanically separate the waste maintenance-free lead-acid storage battery, which not only does not damage the materials but is simple and feasible, and has small secondary contamination, a small energy consumption for recovery and a high recovery utilization such that the resources are fully utilized.
