提出了一种采用组合式旋流器和球形双槽互击喷头的旋流组合式催化裂化进料喷嘴的概念,并针对不同的旋流器组合方式和喷头结构形式开展了旋流组合式催化裂化进料喷嘴液流分布实验,获得了其液流分布特性,初步掌握了喷嘴的雾化性能。结果表明,采用四组合式旋流器和采用内外嵌套组合式旋流器以及球形双槽互击喷头的喷嘴,喷射液层液流分布比较均匀,雾化效果较好;该结果对于进一步改进此类喷嘴的设计具有重要的参考价值。

A new FCC feed injection nozzle, where a combined cyclone and spherical like-doublet impinging injector is used, is presented in this paper, then an experimental study on the combined swirl FCC feed injection nozzle based on different cyclone combination and injector structure was conducted. The results show that the feed injection nozzle with four external combined cyclone, internal combined cyclone and spherical like-doublet impinging injector achieves good results. The result has important values for the improvement of combined swirl feed injection nozzle design.
