Description

Technical Field

[0001] The utility model relates to the technical field of tail gas purification, in particular to a tail gas purification device for industrial waste water treatment. Background Art

[0002] Industrial wastewater refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with the water. In the aeration tank during the wastewater treatment stage, a large amount of sulfide in the wastewater will be discharged into the air, causing pollution, and exhaust gas purification equipment is required to treat these gases.

[0003] Traditional exhaust gas purification devices often adopt a single spraying method, which limits the contact area between chemical agents and sulfide gases, resulting in low purification efficiency and long treatment time. In addition, during the use of the exhaust gas purification device, the sulfide gas is easily attached to the inner wall of the treatment tank after solidification, which not only affects the normal operation of the equipment, but also may cause equipment failure and shorten the service life of the equipment. Therefore, an exhaust gas purification device for industrial wastewater treatment is proposed. Utility Model Content
