Abstract :
Based upon fluid dynamics modeling of gas-solids two-phase flows and Euler-Euler two-fluid modeling approach (TFM), incorporated the kinetic model of heterogeneous catalytic reaction, The spouted bed reactor using activated carbon particles to remove SO2 from flue gases was studied. The distribution of SO2 and overall flow patterns including a stable spout region, a fountain region and an annular down comer region within the spouted bed were obtained well. Then, the simulation results of different operating condition were compared. The results show that the rate of desulfurization in the annular region is much higher. And the temperature of reaction, the concentrations of O2 and H2O in flue gases have a prominent influence on efficiency of desulfurization. Such researches verify that proper reducing the reaction temperature and enhancing the concentrations of O2 and vapor in flue gases will improve the efficiency of desulfurization in the spouted bed.
