Recycling process of used UPS batteries

What is the significance of the recycling of waste UPS batteries? The largest amount of industrial UPS batteries is batteries, and lead accounts for more than 50% of the total cost of batteries. Metal components can be recovered using pyrometallurgical and wet metallurgical processes and electrolysis technologies. The plastic casing of batteries It can also be recycled and recycled, and basically no secondary pollution can be achieved. The purpose of recycling waste UPS batteries is to extract lead and other metal components; the recycling and smelting methods of waste lead-acid batteries: 1. Pyrometallurgical smelting generally involves putting lead paste in In the furnace, the lead paste is melted at a temperature exceeding 1000°C. If coke or coal is used as fuel, a large amount of carbon dioxide, lead-containing dust and sulfur dioxide will appear. 2. Hydrometallurgy Wet smelting transfers the process of pyrometallurgical smelting and recovery of lead paste to the liquid phase, and uses chemical methods to process the lead paste to overcome the high energy consumption, high lead volatilization loss, high pollution and other defects of pyrometallurgical smelting. It has the advantages of high-efficiency production of pure metals, large product output and low emissions. With increasingly stringent requirements for environmental protection, the hydrometallurgical process has received more and more attention in the field of waste battery treatment. The recycling process of used lead-acid batteries: 1. Transport the used UPS lead-acid batteries to the warehouse of the smelting plant using special environmentally friendly vehicles; 2. Pour the electrolyte of the used lead-acid batteries into the sedimentation tank for drug treatment; 3. Dismantle the used lead For acid batteries, send the shell to a plastic recycling plant for professional treatment; 4. Sort the separators of waste UPS lead-acid batteries and send them to a professional factory for recycling; 5. Send the sorted waste plates into a large reverberatory furnace for smelting , Made into lead ingots and recycled; 6. Wastewater from the smelting process flows into the sedimentation tank and is treated with the electrolyte together; 7. The waste residue from the smelting process is sent to a professional iron smelter for treatment; 8. During the smelting process The waste smoke that appears will be safely discharged after being processed by the bag dust removal device. At this point, the environmental recycling process of waste lead-acid batteries ends. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
