摘　　要：利用脉冲喷吹实验,在其他喷吹条件不变时,通过改变无喷嘴无文丘里管、有喷嘴无文丘里管、无喷嘴有埋入式文丘里管、有喷嘴有埋入式文丘里管、无喷嘴有外置文丘里管和有喷嘴有外置文丘里管六种组合方式,测定同一喷吹管上同一喷吹孔位置喷吹时,其滤筒侧壁正压力峰值及其到达时间这两个指标来研究脉冲喷吹滤筒除尘器的喷吹效果,从而研究喷吹组合方式对脉冲清灰性能的影响。通过实验数据分析得出了本实验的最佳喷吹组合方式。Under unchanged pulse-jet conditions, by changing the combination modes including without nozzle and without Venturi tube, with nozzle and without Venturi tube, without nozzle and with submerged Venturi tube, with nozzle and with submerged Venturi tube, without nozzle and with external Venturi tube, with nozzle and with external Venturi tube, conducts the experiment of testing the pressure peak and its reach time of a same injecting hole to study the pulse-jet efficiency and further to study the effect of combination modes on dust-cleaning performances. Obtains the optimum combination mode under the experimental condition by analysing the experimental data.
