含表面活性剂溶液的雾化特性及对细颗粒物的强化去除效果
Atomization characteristics of surfactant-containing solutions and enhanced removal of fine particulate matter
摘要
Abstract
Spraying technology is widely used in the fields of gas purification,dust control and chemical synthesis.Among them,droplet size control and improvement of spray uniformity are the challenges of this technology.For this reason,this paper intends to use surfactants to regulate the atomization characteristics of water mist to improve spray uniformity and further explore its promotion effect on fine particle removal.In this paper,an experimental study was conducted to analyze the atomization characteristics of three surfactants(sodium dodecylbenzene sulfonate,cetyltrimethylammonium bromide,and Tween 80)solutions with different properties,and to investigate the effects of surfactant type and concentration on the atomization characteristics.The results showed that compared with deionized water,the addition of surfactants could significantly improve the spray uniformity,the overall particle size of the spray decreased,and the nonionic surfactant Tween 80(TW80)atomized the highest percentage of small droplets formed.The number of droplets of the three types of surfactant solutions peaked when the surfactant solution concentration reached the critical micelle concentration(CMC),which was taken as the optimal atomization concentration.In addition,the fine particulate removal experiments by spraying showed that spraying with surfactant solutions could accelerate the removal rate of fine particulate.关键词
