▎ 摘　　要

NOVELTY - graphene preparation special integrated waste gas processing device, device comprises four modules: a three-stage spraying module, an electrostatic collecting module, a photocatalyst filtering module and an adsorption module, and each module device inlet is provided with a draught fan to provide power. The utility model is special for the phenolic resin thermal cracking to produce graphene waste gas such as carbon monoxide, carbon dioxide, methane, ethylene, acetylene, benzene, toluene, CnHm alkane, dimethylamine, formaldehyde and formic acid and so on organic volatile gas, and a large amount of carbon particles and a small amount of dioxin and other organic contaminants, such that the finally discharged graphene production waste gas reaches the discharge standard.
