摘　　要： 在液幕式湿法脱硫中,竖直射流回落液量分布情况直接决定脱硫效率。研究了竖直射流液体回落的分布规律。根据单喷嘴实验数据,推导出了“回落液幕无量纲体积流率公式”,此公式各参数有明确的物理意义,可全面描述回落液幕分布特性。通过喷嘴组实验,证明喷嘴组竖直射流回落液量满足多个单喷嘴回落液量简单叠加原理,而且分布均匀性是喷嘴间距和射流高度的函数。 In gas -liquid screen type WFGD, distribution of falling liquid about upright jet determines directly desulfuration efficiency. The distribution of falling liquid flow on upright water jet was studied. According to data of singular nozzle, a formula called dimensionless volume flow rate was drawn. All parameters in this formula are of specific physical meaning, and can be used to indicate distribution characteristics of falling gas - liquid screen. The experiment of nozzle battery showed that falling liquid flow about nozzle battery was the sum of that of singular nozzle. Distribution of falling liquid flow on nozzle battery was the function of nozzle spacing and jet height.
