摘要

摘要: 为了更好地指导风送式抑尘喷雾机喷嘴的选型,收集了5种内部结构的喷雾机喷嘴,对比其雾化特性,并检验选定的喷嘴应用于工程现场的降尘效果。结果表明:1)斯普瑞和泰格两种喷嘴具有较大的雾化角,能满足大面积降尘的需求,适用于大多数抑尘喷雾机;2)同一供水压力下,喷孔直径为0.5 mm的斯普瑞喷嘴雾滴粒径远小于其他结构的喷嘴,将其安装在抑尘喷雾机,能有利于细小颗粒粉尘的捕集;3)将喷孔直径为0.5 mm的斯普瑞喷嘴安装于工程现场抑尘喷雾机,实测全尘降尘效率和呼尘降尘效率分别高于90%和80%,降尘效果良好。

Abstract: To better guide the selection of nozzles of air-assisted dust suppression sprayer, five sprayer nozzles with different internal structures were collected to carry out a comparative study on the atomization characteristics, and the selected nozzles were used in the project site to test the dust reduction effect. The results showed that:1) the Spray and Taige nozzles had larger atomization angle, meeting the needs of large area dust reduction, and were suitable for most dust suppression sprayers; 2) under the same water supply pressure, the droplet diameter of the Spray nozzle with an outlet diameter of 0.5 mm was much smaller than that of other nozzles, and its installation in the dust suppression sprayer was beneficial to fine dust capture; 3) the spray nozzle with an outlet diameter of 0.5 mm was installed in the dust suppression sprayer at the project site, to measure the total dust reduction efficiency and respirable dust reduction efficiency, which were higher than 90% and 80% respectively, and the dust reduction effect was good.
