Description

Technical Field

[0001] The utility model relates to the technical field of gas processing equipment, in particular to a spray absorption device for processing chlorine-containing high-temperature tail gas. Background Art

[0002] Chlorine-containing high-temperature tail gas is generated during the drying and crystallization of chlorides in chemical production, the regeneration of catalysts in petrochemical production processes, or the evaporation and concentration of industrial wastewater. Direct discharge will produce dust and chlorine-containing gaseous pollutants, accompanied by huge thermal pollution. The patent document with publication number CN219682131U discloses a spray absorption device for treating chlorine-containing high-temperature tail gas. The spray absorption device for treating chlorine-containing high-temperature tail gas includes a device body and an external circulation spray subsystem. The external circulation spray subsystem is arranged on the device body. The device body as a whole is a tower-shaped structure. An air outlet is opened on the top of the device body. A water storage subsystem, an air inlet subsystem, an absorption subsystem, a spray subsystem and a demisting subsystem are arranged inside the device body from bottom to top.

[0003] In the above technical solution, when removing fluorine, the exhaust gas is only allowed to passively contact the defluorine structure. More exhaust gas cannot contact the defluorine filter plate within a certain period of time, thereby affecting the efficiency of defluorine removal. Therefore, we propose a spray absorption device for treating chlorine-containing high-temperature exhaust gas to solve this problem. Utility Model Content
