[0003] In the prior art, a chemical waste gas purification tower works by connecting its own gas pipe with an external air duct through a flange. The flanges of the two are fixedly connected by bolts. The chemical waste gas enters the tower from the air duct through the gas pipe, and rises to the packing absorption layer in the tower under the influence of wind, where it reacts chemically with the packing. The incompletely purified waste gas rises to the spray layer in the tower, where the gas and liquid collide, and the absorption liquid contacts and mixes with the waste gas. The treated gas is discharged through the exhaust pipe in compliance with the standards, thereby achieving the purpose of purification.
