摘要

为强化气液离心分离过程

实现在大直径分离器内的气液旋流高效分离

设计构思了一套多旋臂气液旋流分离设备，为气液分离大型化设计提供了一种新思路。在纯气流条件及不同的旋流臂喷出气速下对该分离设备进出口静压差进行了测量，实验结果表明，旋流分离设备静压差在整个运行过程中较为稳定，有较强的可预测性，无量纲标准偏差维持在2%以内，总压降与旋流臂出口气速呈现出良好的平方关系。进一步将总压降分解为入口及旋臂摩擦损失、分离器空间内摩擦损失和出口管路摩擦损失三个部分进行详细测量，获得了各部分压降与旋流臂出口速度头的定量关联模型，发现分离器空间内摩擦阻力损失在总压降中占比最大。GLVS总压降主要受旋流臂出口气速影响，加入液相后对压降影响很小。该旋流分离设备的阻力系数与普通旋风分离器相当，根据四组不同结构尺寸的旋流头得到了阻力系数与旋流头关键设计参数的关联式，为进一步结构优化提供了参考。

Abstract

To strengthen the gas-liquid centrifugal separation process and realize the high-efficiency separation of gas-liquid cyclone in the large-diameter separator

a multi-rotor gas-liquid vortex separation equipment was designed

which provided a new design for gas-liquid separation and large-scale design. It can provide a new idea to design for large-scale gas-liquid separator. The pressure drop characteristics are investigated in a large scale cold-separator model. The static pressure drop between the inlet and outlet was measured at different velocities of the swirling arm under pure air flow conditions. The velocities of the swirling arm ranged from 5.65 to 16.95 m/s

which can cover the operating conditions of the industry gas liquid separator. The experimental results show that the pressure drop and the velocity of the swirling arm presence a square relationship. The dimensionless standard deviation of the static pressure drop is maintained within 2%. Furthermore

the total pressure drop includes three parts

i.e

loss in inlet friction

loss in the separation space

and loss in outlet pipeline. It is found that the pressure drop occur in the separation space is the largest. A model between the pressure drop of

each part and the velocity head of the swirling arm was then given. The resistance coefficient of this rig is 16

it has no significant increase compared to common cyclone separators. The total pressure drop is closely related to the velocity of swirling arm. The change of total pressure drop is slight after feeding liquid. The forecast equation of the resistance coefficient was obtained based on the experimental of four similar structures with different sizes. Compared to real resistance coefficient

the predicted results error is less than 0.5%.
