Problems solved by technology

[0003] However, if the waste lithium-ion batteries are treated with ordinary waste disposal methods (including landfill, incineration, composting, etc.), metals such as cobalt, nickel, lithium, manganese, and inorganic and organic compounds will definitely cause serious damage to the atmosphere, water, and soil. Serious pollution, extremely harmful
[0004] At present, in the recycling process of waste lithium-ion batteries, a large amount of organic waste gas will be produced, which will pollute the environment. Therefore, the organic waste gas generated by the recycling and dismantling of waste lithium-ion batteries must be absorbed and treated, and discharged after reaching the standard

Embodiment Construction

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0029] Such as figure 1 , Is the waste gas spray absorption system for waste lithium batteries of the present invention. The main structure of the system is a spray absorption tower 1, and the absorption tower is provided with an air inlet 11, an air outlet 12, a packing layer 13, a spray device 14 and a sewage outlet 15. Among them, taking the position of the air inlet 11 as the boundary, the absorption tower 1 is divided into two areas. The part above the air inlet 11 where the spray device 14 and the filler 13 are arranged is the spray area, which is located at the air inlet 11 The follo...

Abstract

The invention discloses a spraying absorption system for waste lithium battery disassembly waste gas treatment. According to the present invention, the absorption system adopts an alkaline spraying absorption liquid, and the absorption liquid is subjected to circulation spraying multiple times in an absorption tower; the absorption tower has a simple closed structure, and the liquid circulation isperformed in the absorption tower so as to reduce the overflow of the absorption liquid and the gas and improve the safety of the working environment of the worker; and the absorption liquid is circulated multiple times in the absorption tower to completely utilize the absorption liquid at a maximum so as to save the cost. The invention further discloses a method for applying the spraying absorption system for waste lithium battery disassembly waste gas treatment.

Description

Technical field [0001] The invention relates to the technical field of battery recovery waste gas treatment, in particular to a spray absorption system for dismantling waste gas treatment of waste lithium batteries and a method for applying the same. Background technique [0002] Lithium-ion batteries have the advantages of high energy, long life, low pollution, etc., and are widely used in mobile phones, computers, electric bicycles, electric vehicles, national defense and other fields. Since 2017, with the explosive growth of electric vehicles, the large-scale power lithium battery market will be accompanied by a substantial increase in the demand and scrap of lithium batteries. Improper production and recycling of lithium-ion batteries can also cause pollution. The positive and negative electrode materials and electrolyte solutions of lithium-ion batteries still have a great impact on the environment and human health. If the substances in waste lithium-ion batteries enter the...
