摘要
工业化石燃料的广泛使用造成大量的含硫烟气排放,为了满足环境保护要求必须对烟气进行脱硫处理.膜吸收技术具有脱硫率高、传质效果好的特点,在烟气脱硫领域具有广泛的应用前景.本文以膜材料与膜接触器设计为主线,重点综述了膜接触器在烟气脱硫中的应用情况,分析不同吸收剂对膜吸收过程的影响;总结了无机膜、有机膜、混合基质膜在膜吸收脱硫方面的研究进展;汇总了膜接触器设计方法,以吸收过程阻力串联模型为基础建立相应膜材料与吸收过程的传质模型,利用模型对膜材料、膜组件、操作条件等进行优化.以期对烟气脱硫膜材料和膜接触器设计开发具有一定的参考价值.
The sulfide-containing flue gas produced from extensive use of industrial fossil fuels needs to be desulfurized to meet the requirements of environmental protection. Membrane absorption technology obtains high SO_(2) removal rate and good mass transfer effect that has a wide application prospect in the field of flue gas desulfurization. This work highlights the design of membrane materials and membrane contactors and mainly reviewed the application of membrane contactors in flue gas desulfurization. The influence of different absorbents on the membrane absorption process is analyzed. The research progress of ceramic membrane, polymer membrane and mixed matrix membrane in membrane absorption desulfurization is summarized. This work also reviewed the design and development methods of membrane contactors based on the resistance series model of absorption process. The membrane materials, membrane contactors and operating conditions are optimized by establishing mass transfer model including membrane structure parameters in the paper. Hence, the paper could provide a solid foundation for the design and development of the membrane materials and membrane contactors for flue gas desulfurization.
