摘要 阐述了新型膜接触器由于避免了传统分离设备的一系列缺点和不足,具有操作范围宽,分离效率高,气液两相的流速可独立控制,可直接线性放大和结构紧凑等众多优点,日益成为分离科学研究的热点。并着眼于3种气/液界面膜接触分离过程(膜吸收、膜蒸馏、膜结构填料替代)在废气、废水等环境治理与化工分离方面的研究,从膜接触器结构、膜材料、传质、分离效率等方面详细分析和探讨了三种膜过程的分离特点,并对其作用原理、操作参数及分离性能进行了综合比较。 Compared with conventional separation facilities, novel membrane contactors will play a more and more important role in waste treatment in the near future. The advantages in separation include wider operation range, high separation efficiency, independent flow between liquid and gas, linear scale-up and compact structure, etc. Typical gas/liquid separation processes, such as membrane adsorption, membrane distillation and membrane structured packing in waste treatment and solvent purification are discussed in detail. The performance of different membrane contactors and characteristics of their materials and module structures are also studied with mass transfer analysis.
