摘　　要：为了研究湿式除尘中喷头布置方式对细水雾除尘效率的影响,设计了由粉尘产生系统、喷雾系统、测试系统组成的细水雾除尘实验平台。对不同喷头布置方式下细水雾除尘效率进行了实验研究,得到了喷雾压力和喷头布置方式对细水雾除尘效率的影响:细水雾除尘效率随喷雾压力的增加而提高,但当喷雾压力超过1.6 MPa后提高速率变缓;各个喷雾压力下,双喷头的除尘效果均优于单喷头;喷头距离尘源越远,全部粉尘的除尘效果越好,而呼吸性粉尘的除尘效果越差。In order to study the effect of the nozzle arrangement on the dust removal efficiency by water-cloud,the experimental platform which was made up of dust making system,mist supple system and test system was designed. Experiments on different nozzle arrangements were carried out to obtain the effect of the mist pressure and the nozzle arrangement on the dust removal efficiency. With the mist pressure increasing,the dust removing efficiency improved. But when the mist pressure was over 1. 6MPa,and the increasing of speed was becoming slow. Under different pressure,the dust removal efficiency of double nozzles is better than that of single nozzle. The longer distance between nozzle and dust resource,the higher the dust capture efficiency is,but the lower the respirable dust capture efficiency is.
