Abstract

The invention provides a flue gas purification system capable of efficiently treating flue gas in multiple working conditions. The flue gas produced in various working conditions is transported through the flue gas conveying pipeline to the purification treatment system consisting of multiple independent activated carbon adsorption units or unit groups composed of integrated towers and desorption towers. The flue gas generated in each working condition is passed through an independent Activated carbon adsorption unit or unit group treatment, the activated carbon adsorbed pollutants in the activated carbon adsorption unit or unit group is decomposed and activated by a desorption tower, and then transported to each activated carbon adsorption unit or unit group for recycling. The purification treatment system provided by the present invention treats the flue gas produced in each working condition separately, the flow field of the flue gas in each working condition is not affected, the emission standards are different, and the operating parameters for treating the flue gas in each working condition are different, and then unified The analysis of activated carbon greatly reduces the investment in the analysis tower, saves equipment investment, and improves the utilization rate and work efficiency of the analysis tower.

Description

technical field [0001] The invention relates to an activated carbon flue gas purification system and a control method thereof, in particular to an activated carbon treatment multi-working condition flue gas purification system and a control method thereof, belonging to the technical field of gas purification. Background technique [0002] Iron and steel enterprises are the pillar enterprises of the entire national economy. However, while they make important contributions to economic development, they are also accompanied by serious air pollution problems. There are many processes in iron and steel enterprises that produce flue gas emissions, such as sintering, pelletizing, coking, ironmaking, steelmaking, and steel rolling. The flue gas emitted by each process contains a large amount of dust, SO 2 and NO X and other pollutants. After the polluted flue gas is discharged into the atmosphere, it not only pollutes the environment, but also poses a threat to human health. For ...
