摘　　要：根据水力降尘原理和旋转射流理论,深入分析了影响喷嘴降尘效果的各种因素,并对不同结构喷嘴的喷雾效果进行了实验研究。实验室型式实验表明:所研制的高压射流雾化喷嘴在喷雾压力为10MPa时,具有要求的条件雾化角,合理的雾粒直径、足够的雾粒运动速度,完全满足煤矿井下控制粉尘,呼吸性粉尘的需要,为煤矿安全清洁生产提供了经济有效的手段。According to the principle of hydraulic dust suppression and theory of swirl water jet, all factors, which affect the dust suppression effect, were analyzed.Experiments of nozzles with different structures were done.The results of experiments indicated that these atomized jet nozzles have the required atomized angle, the rational atomization diameter, and the sufficient movement velocity of fog particle under the jet pressure of 10MPa. It can meet the require of dust suppression in underground, especially for respirable dust. The development of this type of nozzles can provide economical and effective means for safety and clean production in mine.
