本文通过对现在实际使用的中空纤维气体分离膜丝内压降的理论分析,认为其规律基本服从微分的Hagen-Poiseuille方程;并将Hagen-Poiseuille方程与渗透方程联立,得到了计算丝内压降的一般方程式;最后经大量的实验,验证了上述论点、和公式的正确性。
In this paper, the theoretical analysis of the pressure drop in the hollow fiber gas separation membrane that is currently used is considered, the law of which is basically obeyed by the Hagen-Poiseuille equation of differential; and the Hagen-Poiseuille equation is established with the permeation equation, The general equation of decreasing; Finally, after a large number of experiments, the above arguments and the correctness of the formula are verified.
