摘　　要：随着隧道建设规模的不断扩大,超长深埋隧道占比不断增大,在其施工建设中会产生大量粉尘,采用干雾除尘的方法进行处理,除尘效果与其雾化效果相关。本文针对超长深埋隧道中干雾除尘雾化效果进行试验研究,以四川某超长深埋隧道为例,采用喷雾雾化特性多参数测试装置并结合MATLAB数字图像处理方法,研究气液压力和气液比对喷雾射程与雾化角的影响,结果显示:保持气压不变时,随着水压的增大,喷雾射程总体上呈现增大的趋势,雾化角呈现减小的趋势;保持水压不变时,增大气压,喷雾射程与雾化角均增大;在气液比一定范围内,喷雾射程、雾化角均随着气液比的增加而增大。The paper makes an experimental study on the ultrasonic automization effect of dust suppression in a certain super-long deeply-buried tunnel in Sichuan Province,in which the influence of gas-liquid pressure and gas-liquid ration on the spray range and spray angle is studied through multi-parameter testing device of automization and MATLAB digital image processing,whose results show that when the air pressure remains constant,there is a trend of increase of the spray range and decrease of spray angle with the increase of water pressure;when the water pressure remains constant,there is a trend of increase of the spray range and spray angle with the increase of water pressure;and the spray range and spray angle increase with the increase of gas-liquid ration within a certain range.
