Experimental Study on Characteristics of Counter-current Hollow Fiber Membrane Modules

利用聚丙烯(PP)中空纤维膜组装成逆流式膜组件,采用实验方法,对加湿工况、除湿工况膜组件特性影响因素进行研究。加湿工况:加湿量随空气质量流量增大而增大,随溶液质量流量增大而增大。加湿效率随空气质量流量增大而减小,随溶液质量流量增大而增大。除湿工况:除湿量随空气质量流量增大而增大,随溶液质量流量增大而增大。除湿效率随空气质量流量增大而减小,随溶液质量流量增大而增大。

Polypropylene(PP)hollow fiber membrane was used to assemble counter-current membrane modules,and the influencing factors of membrane module characteristics under humidification and dehumidification conditions were studied by experimental methods.Humidification condition:The humidification amount increases with the increase of air mass flow rate and solution mass flow rate.The humidification efficiency decreases with the increase of air mass flow,and increases with the increase of solution mass flow.Dehumidification condition:The dehumidification amount increases with the increase of air mass flow and solution mass flow rate.The dehumidification efficiency decreases with the increase of air mass flow,and increases with the increase of solution mass flow rate.
