Model study and flow simulation of circulating fluidized bed flue gas desulfurization(CFB-FGD) were described in this paper. The mathematic model of flue gas desulfurization for circulating fluidized bed(CFB) was built on the basis of element analysis for mass transfer of SO_2.The enhancement of the desulfurization reaction in the process of mass transfer of SO_2 was analyzed with the double -membrane theory in the model.And the real formation process of slurry droplet was accounted with the theory of inertia collision. And then a simulation study of CFB-FGD was conducted based on Aspen Plus,where a module subroutine was programmed in FORTRAN based on this model.The influences of the key parameters such as calcium-to-sulfur ration(Ca/S),flux of spay water,concentration of sorbent particles and water drop size on the desulfurization efficiency were analyzed.The modeling results were compared with the experimental data and the comparing results showed that this model could preferably predict the real trends.This paper would help the application of CFB-FGD as references. |
