| 摘 要： | 为了系统评价天然气净化用旋风分离器在含液量低时的气液分离性能,利用滤膜采样称重法和Welas在线测量法测量了旋风分离器在入口气速8～24 m·s-1、入口液体浓度0.1～2 g·m-3时的分离效率和粒径分布;对比了相同入口浓度下旋风分离器气液分离性能和气固分离性能的异同。实验结果表明,在入口气速为8～24 m·s-1、入口液体浓度为0.1～2 g·m-3时,旋风分离器的气液分离效率随着入口气速和入口液体浓度的增加而增大,而出口粒径分布范围变化很小;与气固分离相比,在相同的入口气速和入口浓度下,旋风分离器的气液分离效率要高2%～6%;另外,气液分离时出口液滴粒径不大于4 μm,而气固分离时出口有大于10 μm固体颗粒存在。

| Abstract: | In order to evaluate the gas-liquid separation performance of cyclone separator for purification of natural gas at low liquid concentration,membrane filtration method and optical particle counter Welas 2000 were applied to measure the overall collections and droplet size distributions,respectively,with inlet velocities of 8—24 m·s-1 and liquid concentrations of 0.1—2 g·m-3 and under atmospheric pressure and room temperature.Comparisons of separation performance have been done between gas-liquid and gas-solid separation under the same inlet velocity and liquid/solid concentration.The results of experiments showed that the gas-liquid separation efficiencies increased with the increase of inlet velocity of 8—24 m·s-1 and liquid concentration 0.1—2 g·m-3.The separation efficiencies of gas-liquid separation were 2%—6% higher than those of gas-solid separation under the same conditions.The droplets with the diameter size bigger than 4 μm could be removed clearly,however,there were particles with the diameter bigger than 10 μm existed in cyclone separator outlet. |
