Description

Technical Field

[0001] The utility model relates to the field of VOCs waste gas treatment, in particular to VOCs treatment equipment for lithium iron phosphate battery diaphragm processing. Background Art

[0002] Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. The rated voltage of the single cell is 3.2V and the charging cut-off voltage is 3.6V-3.65V. In the production process of lithium iron phosphate batteries, some other accessories, such as diaphragms, need to be produced.

[0003] During the processing of lithium iron phosphate battery separators, some VOCs will be generated. VOCs are volatile organic compounds (organic waste gas). Most VOCs have a special unpleasant odor and are toxic, irritating, teratogenic and carcinogenic. In particular, benzene, toluene and formaldehyde can cause great harm to human health.

[0004] Most of the VOCs treatment methods in the prior art use a transmission pipeline and a drainage fan to introduce it into a high-temperature furnace, and use the high temperature inside the high-temperature furnace to heat the VOCs (organic waste gas) to above 760°C, thereby promoting the oxidation and decomposition of the VOCs in the waste gas into harmless CO2 and H20. However, when the drainage fan extracts VOCs (organic waste gas), there is a lack of filtering measures, so that the solid impurities contained in the VOCs (organic waste gas) will enter the high-temperature furnace together, and the solid impurities will subsequently remain in the high-temperature furnace, which will affect its continued operation. For this reason, the present application proposes a VOCs treatment device for lithium iron phosphate battery diaphragm processing. Utility Model Content
