[0002] Lithium batteries are batteries that use lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. They have the characteristics of small size, light weight, high energy density, and long service life. Lithium batteries will inevitably produce waste gas, waste water, waste residue, etc. during the production process. In particular, for the treatment of VOCs in waste gas, an exhaust gas treatment device is needed.

[0003] Traditional exhaust gas treatment devices usually need to go through the processes of electrostatic treatment, alkaline washing treatment, dehumidification treatment, and adsorption treatment. The adsorption treatment uses activated carbon to adsorb organic matter in the exhaust gas. However, after the device has been used for a period of time, a large amount of organic matter exists on the surface of the activated carbon. These organic matter will reduce the adsorption efficiency of the activated carbon, and the activated carbon needs to be disassembled and replaced. However, the activated carbon of the traditional exhaust gas treatment device is fixed inside the device, and the entire device needs to be disassembled to disassemble and replace the activated carbon, which is very inconvenient.
