摘　　要：综述了荷电水雾脱除超细颗粒物的作用机理和影响因素,分析了荷电水雾脱除燃煤电厂烟气中超细颗粒物及综合脱除其它燃煤污染物的可行性,指出利用荷电水雾对燃煤电厂烟气进行处理能够有效提高传统静电除尘器对超细颗粒物的脱除效率,并能实现燃煤污染物的联合脱除,应用前景广阔。Submicron particles can be agglomerated as a result of humifying and Coulomb force provided by charged droplets. This review summarizes the present research situation in the removal of submicron particles by charged water droplets with the introduction of interaction mechanisms and influence factors. Feasibility in the removal of fine particles and simultaneous removal of other pollutants from coal burning in the coal-fired flue is analyzed. Charged water droplets can substantially increase the removal efficiency for fine particles with traditional electrostatic precipitators,which shows a good application prospect for the capability of simultaneous removal.
