[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life. Industrial waste gas discharged by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without being treated and meeting the standards, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. At present, most companies generally use spray tower equipment to treat waste gas. Spray tower is a kind of waste gas purification device commonly used in industrial production. The spray liquid inside the spray tower is mixed with the waste gas to purify the waste gas.

[0003] However, when the traditional spray tower sprays the exhaust gas inside, the liquid is fixed during the downward spraying process, resulting in gaps between the spraying water curtains or incomplete contact with the exhaust gas, resulting in low reaction efficiency and affecting the exhaust gas absorption effect.
