摘要 针对催化裂化密闭快分(CVQS)系统封闭罩内上方存在的非对称不稳定的旋涡流引起的压力不稳定现象,在一套大型冷模装置上,实验测定旋涡流出现的位置与操作条件间的时空特性;为消除不稳定旋涡流,在封闭罩内添加直板形式的导流板,与不添加导流板的装置进行实验对比。结果表明,装置加入合适导流板后,封闭罩内的流场得到改善,有效消除旋涡流现象,减弱了压力波动,使系统的压降明显减小。 In order to study the unstable pressure in closing cylinder of circulation stripping vortex quick separator system because of the asymmetric vortex flow, an experiment was performed to measure the characteristics of time and space between the position of the vortex flow and the operating conditions of the experiment. The guide plate was installed in order to eliminate the unstable vortex flow in closing cylinder of circulation stripping vortex quick separator system. The results show that the flow field in closing cylinder of circulation stripping vortex quick separator system is optimized as the guide plate is installed. On the basis of comparing the experimental data of different structure, the following conclusion can be drawn that the pressure in closing cylinder becomes stable as the vortex flow in closing cylinder is eliminated and the pressure drop in the system is reduced significantly.
