摘要
介绍CS-Ⅱ型高效雾化原料喷嘴雾化原理、性能特点及工业应用效果。武汉分公司催化裂化装置同等加工量下每小时节约蒸汽2.6 t,液化气+轻油收率提高了3.27个百分点,焦炭产率降低了2.1个百分点。显微观察照片表明,更换CS-Ⅱ型喷嘴后待生催化剂挂焦均匀,细粉比例在正常范围内,CS-Ⅱ型喷嘴线速较低,雾化效果较好。
Nebulization principle and property characteristics of CS-Ⅱefficient nebulization feedstock nozzle was described in this paper.Industrial application results of the nozzle indicate that catalytic cracking plant of Wuhan Branch Company save steam 2.6t/h,total yield of liquefied gas and light oil increases 3.27%,yield of coke decreases 2.1%.Micrograph shows catalysts awaiting for regeneration coke uniformly and fine powder ？proportion is within normal range after changing CS-Ⅱnozzle.And CS-Ⅱnozzle has low line speed and good nebulization effect.
