Environment-friendly flue gas desulfurizing system

Abstract

The invention discloses an environment-friendly flue gas desulfurizing system comprising a desulfurizing tower; one side of the desulfurizing tower is connected with a water tank; booster water pumpsare mounted at two ends of one side of the water tank; a connecting pipeline is mounted between the two booster water pumps; an inlet pipeline penetrates through one end of the middle of the connecting pipeline; water spraying holes are uniformly formed in the outer sides of the water spraying pipelines; rotating plates are uniformly mounted on the outer sides of the water spraying pipelines through screws; compared with the prior art, beneficial effects of the method are that water makes contact with flue gas to humidify the flue gas, so that the reaction between the flue gas and slaked limepowder can be accelerated, the reaction speed is increased, meanwhile, the utilization rate of the slaked lime powder can be increased, water sprayed out of the water spraying holes can be scattered while the rotating plates rotate, the contact area between the flue gas and the water is enlarged, and the utilization rate of water resources is increased. Meanwhile, the path between the flue gas andslaked lime is lengthened, so that the slaked lime is reacted more thoroughly, and the desulfurization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to an environment-friendly flue gas desulfurization system. Background technique [0002] Flue gas desulfurization refers to the application of powdery or granular absorbents, adsorbents or catalysts to remove sulfide-containing gases in flue gas. Its advantages are simple process, no sewage, dirty acid treatment problems, low energy consumption, especially The temperature of the purified flue gas is higher, which is conducive to the diffusion of the chimney exhaust, and will not produce the phenomenon of "white smoke". The purified flue gas does not need secondary heating and is less corrosive. [0003] However, when the flue gas is treated now, the flue gas stays in the desulfurization tower for a short time, resulting in a short reaction time of the flue gas in the desulfurization tower, resulting in the slaked lime powder not completely reacting with the sulfur ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an environment-friendly flue gas desulfurization system, which can effectively solve the problem proposed in the above-mentioned background technology. However, when the flue gas is treated now, the residence time of the flue gas in the desulfurization tower is relatively short, resulting in the reaction time of the flue gas in the desulfurization tower. Shorter, resulting in the slaked lime powder not completely reacting with the sulfur in the flue gas, which will lead to waste of slaked lime powder, and at the same time, the sulfur in the flue gas will not be completely removed, causing the problem that the flue gas will pollute the environment again
