Abstract：

Three different structure fiber membrane components were used for low pressure and high humidity air dehumidification, and the influencing factors (inlet pressure, inlet flow rate, scavenging flow rate) on dehumidification performance were also studied. The results show that the membrane component with scavenging gas distributor has better dehumidification performance. Elevating inlet pressure and scavenging flow rate, decreasing inlet flow rate can also enhance the dehumidification performance. Under the operation pressure of 0.03MPa、inlet flow rate of 5 m3•h-1 and 30% scavenging flow rate, the membrane component with scavenging gas distributor can dehumidify the air from 95%RH to 43.5%RH.
