[0002] Corrosive waste gas refers to waste gas containing corrosive substances, such as acidic gas, propylene, chlorine, hydrogen fluoride, etc. These substances will corrode equipment, pipelines, etc., and will also cause harm to the human body. For the treatment of corrosive waste gas, effective purification measures need to be taken, such as wet dust removal, activated carbon adsorption, chemical reaction, etc., to remove or convert the corrosive substances in the waste gas into harmless substances. At the same time, it is also necessary to select a suitable treatment method according to the actual situation to ensure the treatment effect and economic benefits. Among them, propylene is a colorless gas with a slight odor. It is flammable and explosive and harmful to the human body. When the human body inhales corrosive gases such as propylene, symptoms such as coughing and difficulty breathing will occur. In severe cases, it may cause suffocation or death. When treating gases such as propylene, a treatment tower can be used to neutralize the harmful gases in propylene and then discharge them. The problem with the prior art is that the usual spraying method cannot fully neutralize the waste gas in the tower, and when part of the gas is discharged through the outlet pipe, it will cause harm to the human body and pollute the cavity.
