摘　　要：为了研究表面活性剂复配对雾场粒滴粒径特性的影响,自主搭建了实验平台,选取了阴离子型表面活性剂AES、两性离子型表面活性剂LAB-35和非离子型表面活性剂AEO-9,进行二元单体复配,用不同配比的活性剂复配溶液进行实验,对不同压力下雾滴粒径大小及雾滴粒径跨度进行分析。结果表明:当喷嘴直径一定时,表面活性剂复配溶液雾滴粒径随喷雾压力的增大而减小,雾滴粒径分布随压力的增大更均匀;AES与AEO-9复配溶液在配比为5∶1~1∶5范围内,喷雾雾滴粒径均小于AES和AEO-9单体溶液雾滴粒径;AES与LAB-35、AEO-9与LAB-35复配均易于降低LAB-35单体溶液喷雾雾滴粒径。In order to study the effect of surfactant compound on droplet size characteristics in fog field,an experimental platform was independently built in this paper.Anionic surfactant AES,amphoteric surfactant LAB-35 and non-ionic surfactant AEO-9were selected for binary monomer re-combination,and different ratios of surfactant compound solution were used for experiments.The droplet sizes D10,D50,D90,Dvand Δs were analyzed under different pressures.The results show that when the nozzle diameter is constant,the droplet size of surfactant compound solution decreases with the increase of spray pressure,and the droplet size distribution is more uniform with the increase of spray pressure.In the range of 5 ∶1-1 ∶5 ratio of AES and AEO-9 compound solution,the spray droplet particle size is smaller than that of AES and AEO-9 monomer solution.AES and LAB-35,AEO-9 and LAB-35 compounds are all easy to reduce the spray droplet size of LAB-35 monomer solution.
