1987年5月,辽河油田设计院为沈阳油田第二联合站的原油稳定装置设计了一种新型的轻油回收罐——内旋式油气水分离器.1.工作原理内旋式油气水分离器的结构见图1.油气混合物从切线方向进入内旋分离箱(见图2)的中央部分,气流沿着内壁回转.由于离心力的作用,大部分气体聚合在中心位置并通过顶部的通气口流出;而液体和剩余气体,则因气体驱动力的逐渐衰减以及内旋半径的三次增大,继续绕着内壁运动;最后液体沿内旋壁掉入储液段,气体从出口进入沉降分离段.气中携带的大液滴(直径大于130μm)将在沉降分离段进行自由沉降.细小的油
In May 1987, Liaohe Oilfield Design Institute designed a new type of light oil recovery tank-internal rotation type oil-gas water separator for the crude oil stabilization unit of the Second United Station of Shenyang Oilfield. Working principle Internal rotation oil-gas water separation The structure of the device is shown in Figure 1. The oil-gas mixture enters the central section of the internal spin-split tank (see Figure 2) from the tangential direction and the air flow swirls along the internal wall. Due to the centrifugal force, most of the gas is polymerized centrally and passes through the top vent And the liquid and the remaining gases continue to move around the inner wall due to the gradual attenuation of the gas driving force and the increase of the inner rotation radius. Finally, the liquid falls into the liquid storage section along the inner spiral wall and enters the sedimentation separation section Large droplets (more than 130 μm in diameter) carried in the gas will settle freely in the settling section.
