Effect of adjusted mesoscale drag model on flue gas desulfurization in powder-particle spouted beds
文献摘要：
An energy minimum multiscale model was adjusted to simulate the mesoscale structure of the flue gas desulfurization process in a powder-particle spouted bed and verified experimentally.The obtained results revealed that the spout morphology simulated by the adjusted mesoscale drag model was unstable and discontinuous bubbling spout unlike the stable continuous spout obtained using the Gidaspow model.In addition,more thorough gas radial mixing was achieved using the adjusted mesoscale drag model.The mass fraction of water in the gas mixture at the outlet determined by the heterogeneous drag model was 1.5 times higher than that obtained by the homo-geneous drag model during the simulation of water vaporization.For the desulfurization reaction,the experi-mental desulfurization efficiency was 75.03％,while the desulfurization efficiencies obtained by the Gidaspow and adjusted mesoscale drag models were 47.63％and 75.08％,respectively,indicating much higher accuracy of the latter technique.
