摘　　要：基于前期催化裂化旋分式三旋流场及分离性能的数值模拟与实验研究,针对实际生产运行过程分离器制造误差、芯管滞留层等导致的并联旋风分离器不等压降运行的工况,采用实验的方法研究了不同芯管直径的旋风分离器并联后的分离性能,比较了全左旋与左右旋交替排列的并联旋风分离器的分离性能。结果表明,与相同旋风分离器并联相比较,差异分离器并联分离效率降低;全左旋排列的旋风分离器分离效率与压降均高于左右旋排列。Based on the early stage of the catalytic cracking cycle fraction three spiral flow field and separation performance of the numerical simulation and experimental research,according to actual production operation process separator manufacturing error and core tube stranding layer parallel range cyclone pressure drop caused by the operation condition,the article adopts the method of experiment to study the different core pipe diameter parallel after the separation performance of cyclone separator,The separation performance of parallel cyclone separators with full left-hand rotation and left-hand rotation alternately arranged were compared.The results show that the parallel separation efficiency of the differential separator is lower than that of the same cyclone separator.The separation efficiency and pressure drop of the cyclone with full lefthanded arrangement are higher than those with left-handed arrangement.
