The Atomization Mechanism Discuss And Experimental Research On Several Liquid Medium In High-voltage Electrostatic Field

With social development, the electrostatic atomization technology on high voltage of liquid has gained more and more attentions. Its function which applied in industry, agriculture and spaceflight aspect etc. is outstanding in saving material, improving liquid work efficiency, reducing environmental pollution and so on.On the basis of deep research about the history and development of electrostatic atomization, the relation among the effectiveness of liquid electrostatic atomization, the liquid carrying charges and its'charge to mass ratio has been given in this paper. First, a simple discussion for the mechanism about electrostatic atomization of the liquids has been given;Then the paper theoretically analyzed waving course, liquid drop producing course, and the liquid drop diffusing course in electrostatics atomization process.,gave an analysis about the methods about carrying charges to the liquid drop, and analyzed that liquid with high electrical conductivity can be carried charges and atomized by electric field, while the isolated liquid with low electrical conductivity can be charged fully with the soakage electrode and inducing charge methods. At last the paper designed and configured the experimental equipment, conducted the atomization experiment to the three liquid medium-kerosene, emulsifier and alcohol under the same environment, handled the experimental results, then summarized the relationship between liquid electrostatic atomization effect and liquid surface tension, electronic conductivity and viscosity, along with the influence of voltage to electrostatic atomization and so on,found out the liquid atomization rule in high voltage electrostatic field.
