Abstract:In order to analyze the influence of surfactant on the characteristics of dust-removal water mist field, experimental study was made on the parameters of the surfactant-containing water mist field of two kinds of nozzles at three different operating pressures. Three kinds of anionic surfactants were chosen, the surface tension of the solution in different concentrations was measured and the critical micelle concentration was obtained. Study was also made on the influence rule of surfactant upon the water mist atomization cone angle and the mist flow density with measuring cup method, and analysis was made on the influence of the nozzle type, the type and working pressure of surfactant upon the water mist field parameters. The study showed that when the average particle size of the water mists was 200 μm, the surfactant can reduce the mist flow density at the cone, make the peak mist flow density far away from the cone position and the water mist field to be uniformly distributed, increase the atomization cone angle of the water mists, and improve dust-removal efficiency of the water mists;when the average particle size of the water mists was 400 μm, the surfactant has no significant influence on the water mist flow density.
