Performance of Discharge in Two Phase Mixture of Air-Droplet

The influence performances in two phase mixture of air-droplet discharge are analysed in the paper based on the gaseous discharge unit process, and the mechanism in two phase mixture of air-droplet discharge is researched. The research obtains the result not only that the gas spray electrically charged effect is to cause the spatial free electron number to reduce greatly, while is to increase an amount of ions, and discharge phenomena is weakened, but the second voltage increased, intensity of electric field aggrandized too. But also that the free electronic collision frequency in two phase mixture of air-droplet increases every second, and that the collision ionization energy can be reduced, the adhesion coefficient of collision ionization increases, and that ion effective adhesion coefficient increases, and that water mist to the electronic affinity is higher and migration rate of iron is lower. So these factors contribute to the aerosol mixture discharged with a higher voltage, and it is favourable to improve dust performance.
