摘要
利用滤材实验装置,研究了黏度和表面张力等液体物性参数对气液过滤性能的影响。结果表明:液体黏度对滤材压降影响较小,滤材稳态压降基本不变,液体黏度较小时滤材出口液滴浓度较大,且出口有较多粒径较大的液滴;而液体表面张力对滤材压降有较大影响,液体表面张力较大时出口液滴浓度较大。并利用Ohnesorge数对滤材出口液滴浓度进行了分析,Ohnesorge数越大,则出口液滴浓度越低。
The influence of viscosity and surface tension on gas-liquid separation performance was studied in an experimental filter device.The Ohnesorge number was used to analyze the droplet concentration at the outlet of the filter.The viscosity of liquid has little influence on the pressure drop of filter,while the surface tension has a significant influence.Both viscosity and surface tension have significant influences on the outlet droplet concentration.Lower viscosity and higher surface tension lead to higher droplet concentration.Larger Ohnesorge number leads to lower droplet concentration at the outlet.
