摘　　要：对新型油水分离器关键装置柱型旋流器进行了性能实验研究,得到了压降、压降比与进口流量和溢流比之间的关系。结果表明,柱型旋流器内压降随着流量的增大而增大,呈抛物线型增长;压降比与溢流比之间呈线性关系。给出了计算旋流器压降的经验关系式。这些结果对柱型旋流器的设计运行和操作控制有着重要的指导作用,目前已用于南海平台油水分离器的现场实验。The cylindrical cyclone which is an important part of a new-style oil-water separator was studied by experiment.The relationships between pressure drop,pressure drop ratio and inlet flow rate,and flow split-ration were obtained.The experiment results indicate that the pressure drop in cylindrical cyclone increases parabolicallywith the increase of inlet flow rate and the pressure drop ratio is linear with the flow split-ration.An experimental relation is concluded to calculate the pressure drop.These results will improve the local operation of cylindrical cyclone as well as the control performance and guide the local experiment in Nanhai＇s offshore platform.
