As the regard of the serious air pollution in our country , it proposes an outdoor air cleaner which based on electrostatic technology and photocatalysis of TiO 2 .Through CFD ( Computational Fluid Dynamics ) method and analysis of energy consumption , it is proved that this method is feasible .In the 10 m test, the effi-ciency of haze removal is up to 90%, while in the 100 m test, it is 50%.All in all, it is proved that within 100 m, this precipitators can improve the air environment rapidly and efficiently .%针对目前我国出现大范围雾霾天气的状况,提出将静电除尘技术与光触媒催化技术相结合,设计了一种室外空气净化设备.经过CFD理论和能耗分析,论证了方法的可行性.通过对比实验证明该设备对空气污染物的处理效果明显,10 m测试范围的处理效率最大达90%,100 m测试范围的处理效率最大为50%,即该设备在方圆100 m范围内具有快速、有效改善大气环境的作用.
