Abstract: By analyzing for the fine particulate and water droplet forced，a model for submicrometer particulate collected is setup. The collection of the submicrometer particulate is calculated theoretically combining the electrostatic，interception and impaction. The fraction collection curve of submicrometer particulate versus particle diameter under the different water droplet diamete is given out. Results show that the collection efficiency of the submicrometer particle is more than 98%，and the water droplet is less than that of the wet mechanical dust collector，and calculation is consistent within range of error.

Key words: cleaning of submicrometer particle, wet electrostatic precipitator, collection for aerosol particle, removal of fine particulates
