研究了湍流入料对线型中空纤維膜和编织型中空纤维膜的强化分离作用,比较了湍流入料与直流入料对线型中空纤维膜性能影响的差别,进行了迪恩涡强化编织型中空纤维膜与湍流入料强化线型中空纤維膜渗透性能的研究.试验结果显示,湍流入料能显著提高线型中空纤維膜渗透性能,减少浓差极化和膜污染,回收率增大2倍,能耗低20%以上;湍流入料可增大编织型中空纤维膜渗透流量10%左右,能耗降低5%左右,膜组件长度越短,效果越明显.迪恩涡强化编织型中空纤维膜分离性能优于湍流入料强化线型中空纤维膜分离性能,能耗低20%以上,渗透回收率高1~1.5倍图6,参8.
The effect of turbulent flow on the separation of linear hollow fiber membranes and braided hollow fiber membranes was studied. The difference between turbulent inlet and direct inlet on the performance of linear hollow fiber membranes was investigated. Study on the Permeability of Hollow Fiber Membranes and Turbulent Injected Reinforced Linear Hollow Fiber Membranes. The results show that the turbulent feed can significantly improve the permeability of linear hollow fiber membrane, reduce the concentration polarization and membrane fouling, the recovery rate increases by 2 times and the energy consumption is more than 20% Fiber membrane infiltration rate of about 10%, 5% lower energy consumption, the shorter the length of the membrane module, the effect is more obvious. Dean vortex enhanced braided hollow fiber membrane separation performance than turbulent feed linear hollow fiber membrane separation performance, low energy consumption of more than 20%, high permeability recovery of 1 to 1.5 times Figure 6, parameter 8.
