Description

Technical Field

[0001] The utility model relates to the technical field of wet flue gas desulfurization, in particular to a wet flue gas desulfurization tower. Background Technique

[0002] During the industrial production process, some harmful flue gases will be generated. Most of these flue gases contain harmful gases such as sulfur dioxide and nitrogen oxides. When these gases are discharged into the atmosphere, they will cause acid rain and damage the ecological environment. At present, the methods of flue gas desulfurization include dry flue gas desulfurization process, spray dry flue gas desulfurization process, fly ash dry flue gas desulfurization technology, wet flue gas desulfurization process, etc. In the wet flue gas desulfurization system, an alkaline substance (usually an alkaline solution, more often a slurry of an alkali) meets the flue gas in a spray tower. SO2 in the flue gas dissolves in water to form a dilute acid solution, and then undergoes a neutralization reaction with the alkaline substance dissolved in water.

[0003] When using the existing flue gas desulfurization tower to desulfurize flue gas, the flue gas enters the desulfurization tower. The flue gas cannot be fully dispersed and cannot come into full contact with the slurry spray. The flue gas cannot be thoroughly desulfurized, and the desulfurization effect is poor. Moreover, usually there is only one-stage treatment process and the effect is not good.

[0004] Therefore, it is necessary to provide a wet flue gas desulfurization tower to solve the above technical problems. Content of the Utility Model

[0005] The utility model provides a wet flue gas desulfurization tower, which solves the problems in the background technique.
