【摘要】：为解决段塞捕集器下游管道和设备积砂问题,提出了一种带有内旋流和挡板的新型段塞捕集器,采用质量分离效率、粒级效率、压降、临界粒径为评价指标对改造后的段塞捕集器分离性能进行了全面系统的试验评价,结果表明:旋流器能够有效地抑制气体出口携液、携砂,挡板能有效控制液体出口携砂,第1块挡板对分离起主导作用,在第1挡板无量纲长度α10.6或无量纲高度β10.37时,第2挡板强化分离作用明显,改造后的段塞捕集器的砂粒质量分离效率最大值达到95%,临界粒径最小值10μm;增设旋流器后,压降系数增量仅为0.041 5;在气液量波动20%的范围内,改造后的段塞捕集器表现出良好的适应性。
[Abstract]:In order to solve the problem of sand accumulation in the downstream pipeline and equipment of slug trap, a new type of slug trap with inner swirl and baffle is proposed, which adopts mass separation efficiency, grain grade efficiency and pressure drop. The separation performance of the modified slug trap was systematically evaluated with critical particle size as the evaluation index. The results showed that the cyclone could effectively restrain the gas outlet from carrying liquid and sand. The baffle can effectively control the liquid outlet carrying sand, the first baffle plays a leading role in the separation. When the dimensionless length of the first baffle is 伪 10.6 or the dimensionless height 尾 10.37, the second baffle strengthens the separation obviously. The maximum sand mass separation efficiency of the modified slug trap is 95%, and the minimum critical particle size is 10 渭 m. With the addition of hydrocyclone, the increment of pressure drop coefficient is only 0.041 5; The modified slug trap shows good adaptability in the range of gas and liquid volume fluctuation of 20%.
