摘要
由于气液两相流分流分相法计量分离器存在结构复杂、液位难稳定等特点,设计加工了一种新型气液两相流管束分离器,通过数值模拟得到不同气、液相折算速度及不同流型入口条件对管束分离器分离效果的影响,并进行实验验证,对分离器的工作性能进行评估。结果表明:在分层流、段塞流、环状流流型条件下,分离器内气液分离效果较好,且分离器内气液相界面保持稳定,维持在分离器中部。实验验证可知:当气相流量在50~1 500 L/min、液相流量在50~2 400 kg/h范围内时,分离器内气液相界面保持稳定,分离误差均在±2.5%以内,计量效果良好,与模拟结果吻合。设计的管束分离器结构简单、工作液位稳定,为两相流分流分相法计量分离器的设计提供了技术支持。
Gas-liquid two-phase flow metering separators based on the extracting and separating method is disadvantageous with complex structure and unstable liquid level. To deal with this situation, a new type of gas-liquid two-phase flow tube separator was designed and prepared. The effects of gas and liquid superficial velocity and inlet conditions of different flow patterns on its separation result were investigated by means of numerical simulation and then experimentally verified. And the working performance of this separator was evaluated. It is shown that in the patterns of stratified flow, slug flow and annular flow, the gas-liquid separation effect inside the separator is good and the gas-liquid interface inside the separator keeps stable and maintains in the middle of the separator. It is verified from experiments that when gas flow and liquid flow range 50-1500 L/min and 50-2400 kg/h, respectively, the gas-liquid interface inside the separator keeps stable, separation error is less than ±2.5% and metering results are good and accordant with the simulation results. This tube separator is characterized by simple structure and stable working fluid level. It provides technical support for the design of two-phase flow metering separator based on the extracting and separating method.
