Abstract：Aiming at ultra-clean emission requirements for sintering flue gas in iron and steel enterprises，the problems encountered in the process of sintering flue gas desulfurization and dusting were analyzed and swirl atomization desulfurization and dust integration technology was put forward. By constructing a spray tangential swirl field，desulfurization efficiency and dust removal efficiency of a desulfurization tower improved under the influence of turbulent flow，atomization and condensation. The three-day transformation test of a 2×90 m2 sintering unit desulfurization tower was carried out. The test results show that adopting swirl atomizing technology，although the inlet flue gas flow rate，inlet flue gas temperature，inlet SO2 concentration fluctuate sharply，the outlet SO2 concentration can be stabilized below 30 mg/m3 and the desulfurization efficiency can reach as high as 99.22% after reformation. When the inlet dust concentration is 50 mg/m3 and without adding a wet electrostatic precipitator，the outlet dust concentration can be stabilized below 8 mg/m3，the dust removal efficiency can reach as high as 94.3% after reformation，achieving ultra-clean emission of sintering flue gas.
