Abstract:The charged droplets can improve the particle adsorption ability and particle removal efficiency. The adsorption mechanism of particles was established on a single charged droplet experiment system.Using high speed camera and microscopic amplification technology, the motion characteristics of a single charged droplet scavenging particles were investigated. The motion characteristics of particles under the combined actions of electrostatic force, mass force and viscous force were analyzed. The results show that the adsorption ability of charged droplets is better than that of uncharged droplets. The particles can′t overcome surface tension of droplet and deposit on the droplet surface. When particles and particle aggregates fly to charged droplet, parts of them occur scattering phenomenon. The scattering phenomenon and the deposit phenomenon affect the collecting efficiency of charged droplet.
