The gas conveying mechanism is used for conveying the absorbed flue gas, so that the absorption liquid can be fully stirred, the absorption liquid can be utilized to the maximum extent, the efficient utilization of the absorption liquid is realized, and the absorption liquid resource is saved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, and more particularly, to a purification and discharge device for flue gas desulfurization and denitrification and a flue gas comprehensive treatment system. Background technique [0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology used in the chemical industry where polynitrogen oxides and sulfur oxides are generated. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Known flue gas desulfurization and denitrification technologies include PAFP, ACFP, pyrolusite method, electron beam ammonia method, pulsed corona method, gypsum wet method, catalytic oxidation method, and microbial degradation method. [0003] When the existing equipment desulfurizes and denitrifies the flue gas, the solution absorption method is often used in the purification treatment stage. However, the current method generally ...

AI Technical Summary

Problems solved by technology

[0003] When the existing equipment desulfurizes and denitrates the flue gas, the solution absorption method is often used in the purification treatment stage. However, the current method generally directly passes the flue gas into the solution without sufficient stirring of the absorption liquid, which is easy to make the absorption The local absorption of the liquid is saturated, resulting in the inability to maximize the utilization of the absorption liquid and waste the absorption liquid resources
