文摘 本文研究和模拟循环流化床烟气脱硫的流程和模型.以微元分析SO_2的传质为基础,建立循环流化床烟气脱硫的数学模型,模型用双膜理论分析脱硫反应对SO_2传质过程的增强影响,并采用惯性碰撞理论解释浆滴的形成过程.借助Aspen Plus过程模拟平台,用FORTRAN语言编写基于该模型的用户单元模块,模拟循环流化床烟气脱硫工艺,分析Ca/S、增湿水量、塔内颗粒物浓度、水滴粒径等参数对脱硫的影响,模拟计算结果和实验数据的对比显示模型能如实反映实际的趋势.本文为应用循环流化床烟气脱硫技术提供参考.
其他语种文摘 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.
