摘要
本文综述了国内外用膜吸收法治理烟气二氧化硫的研究现状,对采用中空纤维膜吸收过程中的膜组件操作方式、吸收剂、膜材料以及工艺参数的选择进行了介绍,并应用双膜理论对中空纤维膜吸收二氧化硫过程中的各分传质系数和总传质系数进行了推导,初步探讨了建立膜吸收过程数学模型的方法。
In this paper, the nowadaysworld wide study results of the treatment of sulfur dioxide in flue gas were introduced. The mode of membrane module operation, the selection of absorbent, membrane material and process parameter using hollow fiber membrane were explained. Based on Duplex Film Theory, the local and overall masstransfer coefficients of the absorption of sulfur dioxide using hollow fiber were deduced. The foundation method of mathematical model of membrane gas absorption was discussed.
