摘要
为了系统地评价天然气聚结过滤器的气液分离性能,采用两种加入液滴方式,获得较大范围的液滴粒径分布,液滴中位粒径分别为8.7、40.0μm,在流量为94～220m3/h范围内进行实验研究,并通过Winner318B激光粒度仪对出口粒径进行在线测量.实验结果表明：压降会随加液时间发生变化,液滴粒径对分离效率的影响显著;当流量为94～182m3/h、入口液体浓度为30～75g/m3时,气液分离效率随着气体流量和入口液体浓度的增加而增大,当流量超过220m3/h时,分离效率迅速降低;分离器出口处粒径大于8μm的液滴基本除尽。
In order to evaluate the gas-liquid separation performance of natural gas coalescent filter, two ways of putting droplets into the separator were adopted to get larger distribution of the droplet diameter. Having the median particle diameter of 8.71xm and 40.01xm and the flow rate ranging from 94 m3/h to 220 m3/h experi- mented and the droplet diameter at the outlet measured with Winner318B laser particle analyzer shows that the pressure drop varies with liquid-adding time and the droplet diameter influences separation efficiency signifi- cantly which rises with the increase of the air flow rate ranging from 94 m3/h to 182m3/h and the liquid con- eentration changing from 30 g/m3 to 75g/m3. The separation efficiency decreases quickly when the flow rate exceeds 220m3/h and no droplet larger than 81xm can be found at the separator exit. Key words gas-liquid separation, coalescent filtration, separation efficiency, droplet diameter distribution
