摘要

以双流体模型为基础

通过考虑颗粒聚团结构的曳力系数模型来计算非均匀气固相间曳力系数

对循环流化床CO2吸收器内CO2的捕集过程进行了模拟研究

并分析了操作速度、颗粒粒径以及固储量对CO2去除率的影响。结果表明

随着操作速度的降低

CO2去除率得到了明显的提高

颗粒粒径的增大以及固储量的增加在一定程度上促进了CO2的吸收。

Abstract

On the basis of double-fluid model

a simulation was performed in circulating fluidized bed absorbor for carbon dioxide capture process

considered of calculating the inter-phase drag coefficient based on multi-scale approach.The effects of operating velocity

particle diameter and solid inventory on CO2 removal are analyzed.The results indicate that CO2 removal will be enhanced with the decreasing inlet velocity

and improving the particle size and solid inventory will lead to an increase in CO2 removal.
