Simulation Study on the Desulfurization Efficiency Based on Swirl Atomizing

Abstract

Based on the kinetics of chemical reaction, the theory of turbulent diffusion and the theory of mass transfer, the turbulent flow of flue gas in the desulfurization tower was described by standard k –εmodel, and Lagrangian discrete phase model was employed to solve the particle momentum. The SO2 absorption model of wet flue gas desulfurization (WFGD) tower was established, and swirl atomizing layer (SAL) was installed on the tower. The concentration distribution of SO2 was simulated using CFD method. The results showed that SAL could improve the desulfurization efficiency.
