An environmentally friendly flue gas desulfurization system

Abstract

The invention discloses an environment-friendly flue gas desulfurization system, which comprises a desulfurization tower. A water tank is connected to one side of the desulfurization tower. One end of the middle part of the pipe is welded with an inlet pipe, and the outside of the water spray pipe is uniformly provided with water spray holes, and the outside of the water spray pipe is evenly equipped with a rotating plate through screws. Compared with the prior art, the beneficial effect of the present invention makes water and smoke Gas contact can humidify the smoke, so that the reaction between the smoke and the slaked lime powder can be accelerated, and the reaction speed can be accelerated. Scatter, expand the contact area between flue gas and water, improve the utilization rate of water resources, and at the same time make the path between flue gas and slaked lime longer, make the reaction of slaked lime more thorough, and improve the efficiency of desulfurization.

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
