We found that air velocity distribution of self-inhale air circumvolve atomization sprayer is evener than incere cone sprayer at same sprayer outlet section; overall dust-settling efficiency of the two sprayer is similar,but breath dust-settling efficiency of self-inhale is better.
自吸式喷雾器比常规喷嘴的出口风速分布要均匀。 自吸式与常规喷嘴总粉尘的降尘效率差不多，但是对于呼吸性粉尘，自吸式喷雾器降尘效果要好。

该装置对微细粉尘具有良好的降尘效果，降尘效率达到88%以上。
Experimental results also show such device has a better depression effect for fine dust, with the efficiency reaching more than 88%.
本文通过调研发现，我国现有的喷雾降尘方法和降尘设备普遍存在的问题是降尘效率不高，呼吸性粉尘和全尘的沉降率低。
By investigation found that our existing methods of dust spray equipment and the dust is the common problem of dust control efficiency is not high, respirable dust and dust all settlement rate is low.
