主 题：Dust separation Spray mist Electrostatic Dust chamber Laser light attenuation Charging by induction
摘 要：In order to improve the efficiency of reducing fine dust emissions from diffuse sources,the commonly used water mist can be electrostatically ***,the attraction between particles and droplets increases due to electrostatic field *** the experimental investigations carried out,an electrostatic two-fluid nozzle was used to generate a charged spray mist according to the principle of charging by *** a chamber,dispersed dust was precipitated with the spray mist,while detecting the laser light *** means of comparative measurements it could be shown that faster sedimentation and separation takes place through electrostatic *** variations regarding the use of compressed air and water were investigated and the sedimentation time of the particle-droplet mixture in the chamber was shown.A size distribution was then calculated from the laser light attenuation,which shows that the proportion of small particles decreases with spray ***,the influence of the polarity of droplets and solid particles on the reduction measure was determined.
