摘　　要：大部分传统除霾器体积大,需高压电源供电,可移动性差。因此,基于经典法设计了一种新型移动式静电除霾器。在拟定集霾板尺寸的前提下,对于除霾效率为90%的除霾器计算出其荷电电场强度E0约为18.95 k V·m-1。为了使用低压电源得到该高强度电场,建立了芒刺-芒刺移动静电除霾器模型,并利用Ansoft软件对其空间电场分布进行仿真分析。理论分析及仿真结果表明,在使用30 V的直流电源供电时,模型空间场强分布高于18.95 k V·m-1的区域达90%以上,满足雾霾颗粒极化和吸附的条件。同时,制作实物模型并进行除霾实验,实验结果可知实际除霾效率达到88.31%,达到预期效果。所设计的移动式静电除霾器对于清除雾霾具有明显效果,为雾霾清除开创了一种全新的模式,具有重大的工程应用价值。To reduce the large size, high voltage requirement, and immobility of most traditional haze elimina- tors, this study, through the classical method, designed a new type of movable equipment to eliminate haze. With a predetermined size and an efficiency of haze elimination of 90% , charged electric field intensity, E0, was cal- culated as 18.95 kV · m-1. For the creation of E0 by a low voltage source, this study designed a prick-prick model and then simulated the distribution of an electric field in space on the Ansoft. Theoretical analysis and sim- ulation results found that, when supplied by a 30 V DC power supply, the electric field exceeds an area of 18.95 kV · m-1 and accounts for 90% of the volume of the model. Thus, the requirements are met for the elec- tric field to achieve polarization and adsorption of the haze particles. Based on the model, we constructed a haze eliminator with an efficiency of haze elimination over 88.31% that meets the presupposing. In this study, the movable haze eliminator obviously eliminated haze, thus providing an entirely new means of haze elimination. In addition, it offers a great value in terms of engineering applications.
