【摘要】：本文利用聚结滤芯过滤性能的检测装置,通过滤材层数的梯度增加,研究了不同润湿性聚结滤芯内部液体分布特性,分析了滤材层数、滤材润湿性对饱和度、压降的影响。结果表明:随着滤芯层数的增多,亲油型滤材饱和度呈"凹形"分布的趋势愈加明显,即亲油型滤材第一层饱和度数值相同,中间层饱和度逐渐降低,最后一层饱和度又达到一致水平;而疏油型滤材饱和度曲线重合度很好,无明显变化。随着滤芯层数的增多,亲油型滤材与疏油型滤材的总体压降趋势均没有改变,但亲油型滤材润湿压降呈下降趋势,而疏油型滤材润湿压降没有明显变化趋势。
[Abstract]:In this paper, the liquid distribution characteristics of different wettable coalescence filter elements are studied by increasing the gradient of filter layer, and the effects of filter layer number and filter wettability on saturation and pressure drop are analyzed. The results show that with the increase of the number of filter core layers, the distribution trend of oil-lipophilic filter material saturation is more obvious, that is, the first layer saturation value is the same, and the middle layer saturation decreases gradually. The final layer saturation reached the same level again; However, the saturation curve of oil thinning filter material has good coincidence and has no obvious change. With the increase of the number of filter core layers, the overall pressure drop of oil-lipophilic filter material and oil-sparking filter material has not changed, but the wetting pressure drop of oil-lipophilic filter material has a downward trend, while the wetting pressure drop of oil-free filter material has no obvious change trend.
