Abstract To explore the adsorption mechanism of fine particles by fine water mist, the experiment of dust removal characteristics by fine water mist with surfactant was conducted by the spray system with air blowing structure. The effects of droplet size, surfactant concentration and wind speed on the dust control rate were discussed. The experimental results show that with the decreasing of droplet size, the dust control rate increases first with latter decreasing, and there is dust control rate peak. The surfactant solution can markedly improve the rate for different droplets size. The smaller the droplet size is, the more marked the effect is. With the increasing of surfactant mass concentration, the dust control rate is mainly on the rise. The low wind speed is conducive to dust control rate for both pure water and water with surfactant.
