Waste battery recycling system and process thereof

Abstract

The invention provides a waste battery recycling system and process, and the system comprises: a waste lithium battery echelon utilization production line for screening, screening, disassembling and capacity detection on waste lithium batteries are carried out, Pack assembling is carried out on lithium ion single batteries which can be used in an echelon manner; The waste lithium battery echelon utilization production line comprises a waste lithium battery disassembling system, a capacity grading system and a Pack recombination system; the waste lithium battery resource recycling production line is used for recycling lithium ion single batteries which cannot be utilized in an echelon mode and waste lithium ion single batteries generated in the running process of the waste lithium battery echelon utilization production line. And the system also includes a hazardous waste incineration disposal system used for incinerating hazardous wastes generated in the running process of the waste lithium battery echelon utilization production line and the waste lithium battery resource recycling production line. According to the invention, the disassembly and resource recovery of the waste battery and the incineration disposal of the waste battery which cannot be recovered are integrated, so that the environmental pressure of local solid waste stockpiling is solved.

Description

technical field [0001] The invention relates to the technical field of waste battery recovery and disposal devices, in particular to a waste battery recovery and disposal system and a process thereof. Background technique [0002] Since the 1990s, with the widespread use of lithium batteries, my country has become the world's largest producer, consumer and exporter of lithium batteries. Especially in recent years, my country has introduced a series of major policy measures such as purchase subsidies, tax reductions, research and development support, consumption preferences, infrastructure, etc., and the new energy vehicle market is booming. With the rapid development of new energy vehicles, as the "heart" of new energy vehicles, the power lithium battery industry is also growing rapidly. According to the corresponding scrapping standards, the power lithium battery recycling market has been formed. According to the analysis of experts from the Lithium Power Big Data Network...

Problems solved by technology

However, after the sulfate solution is prepared in the traditional extraction process, only drying is used to recover sulfate. Due to the long drying time, the extraction process takes a long time and affects the recovery speed of sulfate.

[0008] 4) When waste lithium batteries are recycled, a large amount of exhaust gas and dust will be generated, which not only increases the pollution of the environment, but also is not conducive to the health of the surrounding people

Because the waste gas will be mixed with the black powder produced during crushing, the conventional waste gas treatment device on the market will not be able to achieve the purpose of collecting the black powder, and the treatment effect on the waste gas is not good

[0009] 5) After the incineration of hazardous waste, nitrogen oxides will be produced, and the flue gas containing nitrogen oxides will be discharged into the atmosphere, which will cause harm to the human body, easily cause respiratory diseases, and cause chemical smog and acid rain. However, the current hazardous waste incineration The system does not effectively deal with nitrogen oxides
