The composition and conditions of enriched sintering flue gas from dry activated carbon method desulphurization of Iron Plant of Taiyuan Iron Steel Group Co.are described.The gas is of low flow,high temperature, high SO_2 and dust content and contains ammonia,fluorine,chlorine,mercury and other harmful impurities. The dilute sulfuric acid washing process with spray tower,1 bubble column scrubber,gas colling tower,2 bubble column scrubber and two-stage wet electrostatic precipitatores is used and clearing equipment is specially designed and selected.The sulphuric acid plant based on a 450 m sintering machine flue gas has operated stably for more than one year and every index of clearing section reaches or exceeds design value,with clearing recovery of 99.01%and 1.4 mg/m~3 dust,and trace amount of sulphuric acid mist,HF,HCl and NH_3 in flue gas at the outlet of clearing section.
