摘要
超音速气液分离技术是天然气脱水工业的一大突破,分离翼是超音速气液分离管的核心部件,是形成高速旋流高效分离的主体。在传统三角分离翼存在诸多不足的基础上提出表面光滑的螺旋拧装式导流叶片的设计,建立旋流管三维物理模型。运用Fluent14.5对气流绕导流叶片的旋流速度场进行了数值模拟,结果显示,在导流叶片尾端气流平均切向速度达到最大值163.28 m/s,气流在导流叶片后可形成较为稳定的强旋流场,x=0.30 m处特征截面的平均切线速度达131.50 m/s,可实现较理想的气液旋流分离。
The technology of supersonic gas- liquid separation is a great breakthrough in the natural gas dehydration industry. The separating wing is a core component of the supersonic gas- liquid separation tube,and it is the main body to form high- speed swirl and separate efficiently. Based on the many shortcomings of the traditional triangle separation wing,the design of the spiral screwing guide vane of smooth surface was proposed,and a three- dimension physical model of eddying tube was established. A simulation of the swirling velocity field by FLUENT14. 5 was also conducted,and the results showed that the average tangential velocity of airflow reached the maximum value of 163. 28 m / s at the end of guide vane,the airflow formed a relatively stable strong swirling flow field,and the average tangential velocity attached131. 50 m / s at the characteristic section of x = 0. 3 m,which can realize the purpose of the gas- liquid swirling flow separation.
