Effective removal of adhesive and fine dusts from flue gas is very difficult. A new method of electrostatic precipitation of the coronadischarges with spraying water(CDSW) was introduced. A new electrode configuration and the circulation spraying of water were employed inthe method. The efficient electrostatic precipitation for adhesive and fine dusts can be accomplished without any drain water during a longoperating period. The fundamental structure, discharge characteristics, mechanism of spraying and precipitation principle of the electrostaticprecipitation using CDSW were described and analyzed. The V-I characteristics, spraying state, supplying water quantity, influence oftemperature and clean of the electrodes were researched in series experiments. The treating effects of circulating spraying using the coronaplasma at the same time of electrostatic precipitation were investigated. The fundamental theories and experimental data were proposed, in orderto effectively remove the adhesive dusts from flue gas using CDSW in practice.
