Problems solved by technology

In addition, due to the high content of halogen, sulfur, phosphorus and other elements in the exhaust gas, and these elements have a poisonous effect on the catalyst, the service life of the catalyst is not long, so the catalyst needs to be replaced frequently, and the operating cost is high

Embodiment Construction

[0009] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0010] A waste gas treatment process. The waste gas is collected and transported to the cyclone dust collector through a collection pipe for dust removal treatment. The waste gas with a temperature of 35-40°C and a pressure of 4000-12000 Pa is uniformly sent to the regenerator through a gas distributor. Absorb the heat stored in the regenerator in the regenerator, heat the exhaust gas temperature to above the decomposition point temperature of the organic matter in t...

Abstract

The invention discloses a waste gas treatment technology. The waste gas treatment technology is characterized by carrying out dust removal treatment by collecting a waste gas through a collection pipeline and conveying the waste gas to a cyclone dust remover; uniformly feeding the waste gas of which the temperature is 35 to 40 DEG C and the pressure is 4000 to 12000 Pa into a heat accumulation chamber through a gas distributor, and absorbing heat accumulated in a heat accumulator in the heat accumulation chamber by the waste gas; heating the temperature of the waste gas to be higher than the temperature of a decomposition point of an organic matter in the waste gas, then introducing the waste gas from an air pipe into a purifying tower, enabling the waste gas to pass through a filler layer, and carrying out gas-liquid two-phase sufficient contact absorption reaction on the waste gas and absorption liquid; dewatering and demisting through a demisting plate after purifying the waste gas,and then discharging the waste gas by a draught fan; downwards spraying the absorption liquid from the tower top after being pressurized by a water pump at the tower bottom, and finally refluxing tothe tower bottom for recycling; then enabling the absorption liquid to pass through a spraying tower, spraying water through the water pump, and carrying out UV (Ultraviolet) photolysis purification treatment after adhering most of organic matters and dust to water, and discharging a small amount of organic waste gas.

Description

Technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment process. Background technique [0002] At present, in the waste gas production industry, the following three methods are mainly used to treat the waste gas generated during the production process. One is the water absorption method, the second is the catalytic incineration method, and the third is the thermal incineration method. The water absorption method is the last process of maleic anhydride production for water absorption treatment of maleic anhydride waste gas. Because maleic anhydride waste gas contains benzene, benzene is difficult to dissolve in water. Therefore, using this method to treat maleic anhydride waste gas has a poor effect. Catalytic incineration is to preheat the maleic anhydride exhaust gas to the ignition temperature of the catalyst. After preheating, the exhaust gas enters the catalytic reactor to cause the organic matter in ...
