操作参数对柱形旋流器油水分离性能的影响

为了判断柱形旋流器的结构设计是否满足实际生产需要,从操作参数的角度研究了油水混合物流速和分流比对柱形旋流器油水分离性能的影响。基于柱形旋流器内部的流动特征,分析了油滴分离的临界条件,得到了油滴从溢流口流出的临界粒径计算公式。分析结果认为,随主管路中油水混合物流速的增加,从溢流口流出的累积油相体积先增大后减小;在溢流口流量一定的前提下,溢流口含油体积分数先增大后减小,理论分析与试验得到的结果一致。

The effect of operating parameters on the oil-water separation performance of the cylindrical cyclone

To make a judgement of whether the structural design of cylindrical cyclone meets the needs of practical production,the effect of the velocity and shunt ratio of the mixture on the oil-water separation performance of the cylindrical cyclone was studied from the perspective of operating parameters.Based on the flow characteristics of the cyclone,the critical condition for oil droplet separation was analyzed and the critical particle diameter calculation formula for oil droplets to flow from the overflow outlet was obtained.The result indicated that,with the increase of the mixture velocity in the main pipeline,the cumulative oil phase volume from the overflow outlet increased first and then decreased.In the precondition that the flowrate at the overflow outlet was fixed,the oil content of the overflow outlet increased first and then decreased.The theoretical analysis was in agreement with the result obtained.
