| 摘 要： | 静电增强颗粒层除尘器（EGB)是一种新型高故除尘器。本文采用孤立球模型，推导出孤立颗粒的截留效率计算式和静电效率计算式，进一步提出了EGB除尘总效率计算式。经过颗粒层除尘器(GB)和EGB除尘效率对比实验研究表明：静电能明显提高除尘效率，为设计和研制高故颗粒层除尘器提供了理论依据。

| Abstract: | Electrostatically, enhanced granular bed filter(EGB)is a modern filter.In this article,the formula of interception efficiency and electrostatical attraction efficiency of the single granular is proposed by adopting the single sphere model.Moreover,the total efficiency formula of EGB is presented.The research results based on the comparative experiment of the granular bed filter(GB)and EGB demonstrate that static electron can obviously enhance dust-collection efficiency and provide theoretical basis for designing and making highly efficient GB. |
