微孔材料对气携式液-液水力旋流器性能的影响

在常规脱油型水力旋流器的基础上,通过结构设计制成气携式液-液水力旋流器,旨在提高其除油效率。介绍了气携式液-液旋流分离的基本原理、样机结构及实验工艺流程,该旋流器的部分旋流体由微孔材料制成。研究了微孔材料对水力旋流器分离性能的影响,如微孔直径、微孔材料安装位置等。试验研究显示,20~40μm孔径的微孔材料可获得最佳旋流分离效果,小锥段微孔注气的效果最佳。对微孔材料的SEM分析表明,试验1个多月后微孔未发生堵塞现象。

Influence of micro-pore materials on the air-injected hydrocyclone

On the basis of the normal de-oiling hydrocyclone, the air-injected hydrocyclone was manufactured by structural design for the purpose of enhancing the de-oiling efficiency. The basic mechanism, the prototype configuration and the experimental process of the hydrocyclone were introduced. Part of the cyclone body was made of micro-pore material. The effect of micro-pore materials on the separation performance of the hydrocyclone was studied, including the micro-pore diameter and the installation position of the micro-pore materials. The experimental research shows that the micro-pore material of 20-40μm seems to be the best for air-injected hydrocyclonic separation. At the same time, the effect of using the small micro-pore cone section to inject air is the best. The SEM analysis of the micro-pore materials indicates that no blockage occurred inside the micro pore after more than one month of experiment.
