　　How to recycle used battery 18650 rechargeable?

　　Recycling of used UPS batteries refers to the reuse of used batteries through recycling. The most commonly used industrial battery in China is lead-acid battery. Lead accounts for more than 50% of the total battery cost. It mainly adopts fire method, hydrometallurgical process and solid-phase electrolytic reduction. technology. The shell is made of plastic and can be recycled, basically achieving no secondary pollution.

　　The recycling and reuse of waste lead-acid batteries is mainly used to extract lead and other metals.

　　1. Fire smelting

　　Pyrometallurgical smelting generally places lead paste in a furnace and melts the lead paste at temperatures exceeding 1000°C. If coke or coal is used as fuel, a large amount of carbon dioxide, lead dust and sulfur dioxide will be produced.

　　2. Hydrometallurgy

　　Hydrosmelting transfers the process of recovering lead paste from pyrometallurgy into the liquid phase, and uses chemical methods to process the lead paste to overcome the shortcomings of pyrometallurgy such as high energy consumption, high lead volatilization loss, and high pollution, and has the ability to efficiently produce pure metals. , large product output and low emissions. With increasingly stringent environmental protection requirements, hydrosmelting processes have received more and more attention in the field of waste lead-acid battery processing.

　　Waste lead-acid battery recycling process:

　　1. Transport used battery 18650 rechargeable to the smelting plant warehouse using special environmentally friendly vehicles;

　　2. Pour the electrolyte from used lead-acid batteries into the sedimentation tank for drug treatment;

　　3. Dismantle the used lead-acid batteries and send the shells to plastic recycling plants for professional processing;

　　4. Sort the separators of used battery 18650 rechargeable and send them to professional factories for recycling;

　　5. Send the sorted waste plates to a large reverberatory furnace for smelting and make lead ingots for recycling;

　　6. The wastewater generated during the smelting process flows into the sedimentation tank and is treated with the electrolyte together with the electrolyte;
