Physical environmental protection technology for the recycling and reuse of waste lithium batteries

With the popularity of electronic products such as mobile phones, notebook computers, and digital cameras, the processing and consumption of lithium batteries have risen sharply, resulting in an alarming 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 also causes 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 powder phenomenon in the battery recycling process. , To make the battery cycle life long, but also to reduce the utilization rate of the active substance in the plasma and the binder content. The lithium battery recycling and processing equipment uses multi-knife to crush the materials, and the air flow sorting equipment separates the materials. The dust in the separation process and subsequent processes is collected by the pulse dust removal equipment. It constitutes a green battery life cycle and a high-quality closed-loop circulatory system. Lithium battery recycling equipment technology: The material is transported to the first stage through a conveyor for coarse crushing. The coarsely crushed materials are sent to the secondary crusher by the conveyor for secondary crushing. After being crushed for the second time, the material enters the conveyor, and the magnetic separation equipment is set together with the conveyor to separate iron. 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 the powder enters the cyclone separator from the negative pressure air filtration system, and the air flow through the fan is separated from the autumn separator and the air flow separator. The materials of different densities are layered, the metal is separated, and all non-metals are separated from the negative pressure system. The concentration of the pulse dust collector. The filtered exhaust gas is continuously transported to the exhaust gas treatment equipment through the negative pressure system for air purification to make it meet the emission standard, and then discharged at high altitude. The recycling and treatment equipment of waste lithium batteries mainly adopts physical recovery methods, supplemented by three waste treatment methods, which are characterized by green, low-carbon, energy-saving, environmentally friendly, no secondary pollution, and coordinate economic and environmental benefits, thus not only completing the use of valuable Ingredients, but also harmlessly processed 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%.
