根据过滤机理所概括得出的,且在一定程度上又是基于实验资料之上的一些理论和经验公式,进行大量的运算,获得了一系列计算图表和曲线。它们可供研究纤维型滤料时预测性能或定性分析用。以下列举部分代表性图表,并予以说明。所列图表的计算条件是温度20℃、760毫米汞柱大气压、滤料填充密度α=0.02(图5除外)、滤速v=20厘米/秒(图2、3 According to the generalization of the filtering mechanism, and to a certain extent, based on some theoretical and empirical formulas based on experimental data, a large number of operations were performed and a series of calculation charts and curves were obtained. They can be used for predictive performance or qualitative analysis when studying fiber-type filter media. The following are some of the representative charts and illustrate them. The calculated conditions for the charts are 20°C, 760 mmHg atmospheric pressure, filter packing density α = 0.02 (except for Figure 5), and filtration speed v = 20 cm/s (Figures 2 and 3).
