Research on Flue Gas Desulfurization Technology for Hot Blast Furnaces in Ironworks
Based on the implementation of the flue gas desulfurization project for a blast furnace hot blast stove in a certain ironmaking plant,this paper introduces the process technology routes for end of pipe flue gas treatment,such as SDS method,fixed bed or moving bed desulfurization process,and microcrystalline adsorption process for front end gas treatment.The hot blast stove in the ironmaking plant is purified and treated for flue gas desulfurization,in order to ensure that the SO2 emissions from the hot blast stove flue gas meet the standards after the combustion and use of blast furnace gas.After the implementation of this technical solution,the hourly average concentration of SO2 emissions in the flue gas of the hot blast stove is less than 35 mg/m3.
