The physical environmental technology of waste li-ion battery recycling

Source: 2020 - 03 - 29 even hits: time as mobile phones, notebook computers, digital cameras and other electronic products, the production and consumption of the lithium battery has skyrocketed, led to the alarming number of waste batteries. However, due to technical and economic reasons, the recovery rate of lithium battery is very low, a lot of abandoned waste lithium battery, caused great threat to the environment and pollution, also caused the waste of resources. Then the key technology of waste li-ion battery: the lithium battery pole piece can reduce foil appearance, is the use of invasive stock progress, and progress of the anode materials and collecting liquid ( Aluminum foil) Bond performance, reduce the battery recycling powder phenomenon in the process, make the battery cycle life is long, also can reduce the plasma guess the progress of the utilization of active material binder content. Lithium battery recycling equipment using multiple blade material crushing, air separation equipment for material separation processing, separation process and the subsequent process of dust collected by pulse dust removal equipment. Constitute the green battery life cycle, high quality of the closed-loop system. Lithium battery recycling equipment technology: materials through the conveyor to the first-level coarse crushing. After coarse crushing materials by conveyor, to the secondary crusher for secondary crushing. After secondary crushing material into the conveyor, together with the conveyor set magnetic separation equipment, can undertake separation of iron. After material conveyor and remove the iron magnetic separator, divide materials into three fine grinding crusher. This kind of material made into powder. Materials in powder into the cyclone separator from the negative pressure air filtration system, through the fan's air flow, air separator and autumn separator separation, the materials of different density is layered, the separation of metal, non-metallic from all the negative pressure system of the concentration of the pulse dust collector. Filtered flue gas by negative pressure system to continue to air purification, waste gas treatment equipment to the emission standards, then emissions at high altitudes. Lithium battery recycling scrap processing equipment mainly USES the physical recovery method, supplemented by 'three wastes' treatment methods, characteristics of green, low carbon, energy saving, environmental protection, no secondary pollution, and coordination of economic and environmental benefits, thus not only completed the use of valuable elements, but also harmless disposal of harmful ingredients. The whole process of recycling has been fully completed, industrial automation degree is high, high recovery efficiency, strong processing capacity. Processing capacity is 500 kg per hour, 5000 tons a year. Rate of waste lithium batteries of valuable components are more than 90%.
