In recent years, with the increasing awareness of environmental protection and the continuous consumption of natural resources, environment-friendly lithium-ion batteries have been developed and widely used. With the advantages of high operating voltage, small size, light mass, high energy, low pollution and long cycle life, lithium-ion batteries have become the absolute mainstay of the target market for new energy vehicles, cell phones, digital products and electric tools, and their number will grow explosively with their popularization and application in powered vehicles and high-power energy storage facilities.
Since 2010, the total global lithium-ion battery production has grown at an average annual rate of more than 25%, and the total global lithium-ion battery shipments reached 115.4 Gwh in 2016, up 21.1% year-on-year from the previous year. It is expected that in 2020, global lithium-ion battery shipments will reach 265.7 Gwh, 2.5 times more than in 2016. And with the development of the industry, the output value of the lithium-ion battery industry is also growing rapidly. Data show that the global lithium-ion battery cell output value reached 185 billion yuan in 2016, and it is expected that the global lithium-ion battery cell output value will reach 343.6 billion yuan by 2020.
The huge consumption of battery production brings a staggering number of waste lithium-ion batteries, which include a large number of valuable metal ions such as cobalt, nickel, manganese, copper, aluminum, lithium and other substances with high recycling value. In line with the principle of protecting the environment and resource recycling, under the premise of environmental protection and safe utilization, priority is given to resource recycling to reduce resource waste. For recycling technology is mature waste lithium-ion batteries, encourage to collect and use.
Lithium battery recycling equipment crushing and recycling waste batteries are collected by air collection hood or equipment with its own air collection system, and the fluoride and VOCs generated from the process of battery shredding and drying are collected through "lye spray tower 1# + lye spray tower 2# + low temperature plasma purification device 1# + low temperature plasma purification device 2# + activated carbon fiber adsorption device 1# + activated carbon fiber adsorption device 2#". After treatment, the dust generated from crushing, airflow sorting, primary screening, crushing, rotary screening, secondary screening, tertiary screening, conveying, etc. is discharged through a 15m high exhaust pipe. "After treatment, it is discharged through a 15m high exhaust pipe; the dust generated in the process of product drop at the discharge port is controlled by setting up a closed bagging room at the drop port, with the bag opening close to the drop port, etc. The dust at the drop port settles in the bagging room. Each exhaust gas of the project can meet the standard emission, and the impact on the surrounding air environment is small after prediction. During the operation period, measures such as sound dissipation, sound insulation, shielding and vibration damping installation are adopted to reduce the impact of noise on the surrounding environment. Solid wastes are properly disposed of during the operation period, so the construction of this project has less impact on the surrounding enterprises.
Lithium battery recycling equipment crushing and recycling project in the construction, operation process will produce certain pollutants, after analysis and evaluation, the use of scientific management and appropriate environmental management means can effectively control environmental pollution. After implementing the risk prevention measures, strictly adopting the environmental protection measures proposed in this evaluation, implementing the environmental management and monitoring plan and the total amount of major pollutants control program, the impact of the project on the surrounding environment can be controlled within the permissible range of relevant standards and requirements, and will produce good social, economic and environmental benefits. The project meets the requirements of circular economy and can effectively promote the sustainable development of waste battery recycling. Therefore, from the perspective of environmental impact analysis, the construction of this project is feasible.
