Waste gas treatment system for treating waste gas in chemical reservoir area

The utility model discloses a waste gas treatment system for treating waste gas in a chemical reservoir area. The waste gas treatment system comprises a VOCs (Volatile Organic Compounds) conveying and condensing device and a VOCs adsorption and desorption device, the VOCs conveying and condensing device comprises a first VOCs conveying path and a VOCs condensing path; the VOCs adsorption and desorption device comprises a second VOCs conveying path, an adsorption and desorption path and a hot nitrogen stripping path. According to the VOCs conveying and condensing device disclosed by the utility model, the treatment procedures of conveying, cooling and condensing and three-stage condensing of VOCs are reasonably regulated, so that moisture in waste gas is condensed while energy conservation and consumption reduction are realized, and each condensing box is ensured to keep good heat exchange efficiency; the VOCs adsorption and desorption device reasonably standardizes condensed VOCs waste gas conveying and hot n
