摘要

在对油气分离器内气相流场模拟计算的基础上

采用随机轨道模型对不同直径油滴在分离器一次油分内的运动轨迹进行了模拟计算

并使用Malvern粒度分析仪对油分离器一次油分出口处的油滴直径分布特征进行了实验测量

同时对排气压力和喷油量变化对一次油分效率的影响进行了测量.结果表明:不同直径的油滴颗粒的运动轨迹差别较大

其分离时间和分离效率也截然不同

直径较大的颗粒较容易分离下来; 油滴的入射位置对其运动轨迹及分离时间也有明显的影响.随喷油量的增加

油气混合物中大直径油滴增多

一次油分效率增高; 一次油分效率随排气压力的升高先提高后降低

排气压力为0.65 MPa时

一次油分效率最高.模拟计算表明:此分离器一次油分能够完全分离的最小油滴直径为16 μm; 实测油气分离器出口处油滴的最大直径介于17.7～20.5 μm之间

所占体积分数为0.2%.实验结果与数值计算结果基本吻合.

Abstract

Based on the numerical simulation of gas flow in an oil-gas separator

traces of different diameter oil droplets in the separator were simulated using the discrete random walk model. The sizes of oil droplets at the outlet of the oil-gas separator were measured by Malvern analyzer. Separation efficiency of the separator was tested with different discharge pressure and mass of oil injection. The results show that the traces of different diameter oil droplets are different

and the corresponding separation efficiency and the separation time are not the same. The larger diameter oil droplets are separated easily. The separation efficiency increases with the increase of the oil injection mass

however

it increases and then decreases with the increasing discharge pressure. When the discharge pressure was 0.65 MPa

the maximum separation efficiency is obtained. The simulation results indicate that under the calculation condition

the minimal diameter of oil droplets separated completely by the separator is 16 μm. And the measured maximal diameter of oil droplets at the separator outlet is from 17.7 μm to 20.5 μm. The simulation results are in agreement with the experimental data.
