Physical environmental protection technology for recycling waste lithium batteries

Physical environmental protection technology for recycling waste lithium batteries With the popularization of mobile phones, notebook computers, digital cameras and other electrical appliances, the processing and consumption of lithium batteries have risen rapidly, and the huge processing and consumption of batteries has led to an astonishing number of waste batteries. However, due to technical and economic reasons, the recycling rate of lithium batteries is very low, and many used lithium batteries are discarded, which poses a great threat and pollution to the environment and is also a waste of resources. At that time, the key technology of lithium batteries was wasted: lithium battery pole pieces can reduce the appearance of the foil, which is an invasive use of stock progress, and the progress of anode materials and the adhesion of the collected liquid (aluminum foil) to reduce the phenomenon of battery powder drop. In the middle cycle, the battery has a long cycle life, but it also reduces the utilization rate of the active material in the plasma and the binder content. The lithium battery recycling and processing equipment uses multiple knives to crush materials, and uses airflow separation equipment for separation processing, and is equipped with pulse dust removal equipment to collect dust that occurs during the separation process and subsequent processes. A green, high-quality closed-loop system for the full life cycle of the battery is formed. Lithium battery recycling technology equipment: the material of the conveyor is sent to the first level of coarse crushing, and the coarsely crushed material is sent to the secondary crusher through the conveyor for secondary crushing, and the material of the second destroying machine is put into the conveyor and The magnetic separation equipment is set at the same time, so iron can be solved. After the material conveyor and magnetic separator take out the iron, the material is divided into three crushers for fine crushing. This material is made into powder. The material in powder condition enters the cyclone separator from the negative pressure air filter system, and is separated by the fan air separator and the air separator. Therefore, the materials of different densities are layered, the metal is separated, and all non-metals are pulsed by the negative pressure system. Dust collector aggregates. The filtered exhaust gas is continuously delivered to the exhaust gas treatment equipment through the negative pressure system for air purification, so that it can meet the emission standard before being discharged at high altitude. Waste lithium battery recycling and treatment equipment mainly adopts physical recovery methods, supplemented by three garbage treatment methods, with the characteristics of green, low-carbon, energy-saving, environmental protection, and no secondary pollution, and overall economic and environmental benefits, not only completing the use value of components , And harmlessly dispose of harmful ingredients. The entire recycling process has been completely completed, with high industrial automation, high recycling efficiency and strong processing capacity. The production capacity is 500 kg per hour and 5000 tons per year. The recycling rate of valuable components of waste lithium batteries is more than 90%.
