摘要/Abstract

摘要： 通过气固、气液交替和混合过滤实验，研究了天然气工业用滤芯气液固三相过滤性能. 通过观测滤芯表面显微结构，研究了不同阶段滤芯压降变化的原因和过滤机理. 结果表明，在相同过滤条件下，含尘滤芯气液过滤时，由于液滴与滤饼层相互作用，滤芯表面纤维结构不断变化，依据压降的变化趋势，过滤过程可分为4个阶段：气固过滤、表面滤饼层脱落、液滴填充及表面过滤. 含液滤芯气固过滤可分为初始过滤和粉尘填充2个阶段；滤芯持液量不同，气固过滤压降呈相似变化规律. 三相过滤压降的增长速率介于气固过滤和气液过滤之间，液滴可有效抑制气固过滤压降的增长.

Abstract: The characterization of industrial filter was investigated by alternation of gas?solid, gas?liquid filtration and gas?liquid?solid filtration experiments. By observing the microstructure of the filter surface, the reason of the filter pressure drop change and the filtration mechanism were demonstrated. The results showed that under the same filtration conditions, during gas?liquid filtration using solid?containing filter, due to the interaction between the droplets and the filter cake layer, the structure of the filter surface changed. The filter pressure drop can be divided into four stages: gas?solid filtration, cake layer abscission, droplet filling and surface filtration. Gas?solid filtration of liquid-containing filter can be divided into two stages: initial filtration and dust filling. Although liquid holdup of filter was different, and the pressure drop of gas?solid filtration was similar. And the growth rate of pressure drop in three-phase filtration was between the solid filtration and the liquid filtration, therefore the droplet can effectively suppress the pressure drop growth.
