摘　　要：通过冷模试验测试了催化裂化装置喉管式进料喷嘴的雾化效果,并对比分析了喉管式、气泡雾化和旋流气泡式喷嘴的雾化性能。结果显示:喷出的雾滴粒径均随着气液质量比(简称气液比)的增加而减小,随着距离的增加而增大;喷雾速度均随着气液比的增加而增高,随着距离的增加而降低;喉管式喷嘴喷出的雾滴在扇面上的分布较为均匀,气泡雾化喷嘴的喷雾在扇面上出现了分区,旋流气泡式喷嘴的操作稳定性较差,布气管在使用一段时间后发生堵塞,而气泡雾化喷嘴和旋流气泡式喷嘴喷雾的雾滴粒径和粒径分布、喷雾速度优于喉管式喷嘴。研究结果可为开发低气液比、小粒径的节能高效雾化喷嘴提供基础试验数据。The atomization effects of the throat nozzles was tested through cold model experiments,and the atomization characteristics of the throat nozzles,bubble atomization nozzles,and swirl bubble atomization nozzle was compared and analyzed.The results showed that:the spray particle size decreases with the increase of the mass ratio of gas to liquid(referred to as gas-liquid ratio),and increases with the increase of distance;the spray speed increases with the increase of gas-liquid ratio and decreases with the increase of distance;the spray droplets from the throat nozzle are evenly distributed on the sector,and the spray droplets of the bubble atomization nozzles appears zoning on the sector.The operation stability of the swirl bubble atomization nozzle was poor,and the gas distribution pipe was blocked after using for a period of time.The droplet size,particle size distribution of the bubble atomization nozzles and swirl bubble atomization nozzled,and the spray speed were better than those of the throat nozzles.The conclusions obtained can provide basic experimental data for developing energy-saving and efficient atomizers with low gas-liquid ratio and small particle size.
