摘要
工业烟气中经常含有大量油性气溶胶,而传统过滤材料基本都是亲油性的,导致吸附污染严重。双疏型膜材料在面向高湿、含油性气溶胶的复杂烟气体系时,具有分离效率高、抗污染性强和易清洁等优点。本文系统总结了用于空气净化过程的双疏膜材料制备方法,通过对应用过程油性气溶胶与膜表面之间的微观作用分析,阐释了影响膜污染形成与控制的表界面作用机理。最后,对双疏膜材料在空气净化领域的发展前景做了分析和研讨。
Industrial flue gas usually contains a large number of oily aerosols,which may lead to serious plug for the traditional oleophilic filters.When facing the complex flue gas system with high humidity and oily aerosol,the amphiphobic membrane material has the advantages of high separation efficiency,strong pollution resistance and easy cleanin.This paper systematically summarizes the preparation methods of air purification amphiphobic membrane.The formation and control mechanisms of foulants on the surface of the membrane are elaborated through analyzing the microscope interaction between the oily aerosols and the membrane surfaces.Finally,the development prospect of amphiphobic membranes in air purification field is analyzed and discussed.
