【摘要】 提出一种高效去除微细颗粒物的偶极荷电静电凝并除尘装置,其主要由凝并区和收尘区组成。对其凝并收尘机理进行了分析,并对收尘性能进行了实验研究。结果表明,偶极荷电静电凝并系数高于库仑凝并系数;偶极荷电静电凝并除尘器中颗粒的凝并效果好,且在相同的条件下,其对微细颗粒物的除尘效率明显高于普通静电除尘器。更多还原

【Abstract】 Dipolar charging electrostatic agglomerator which consists of agglomeration zone and collection zone is developed.The agglomerator can collect fine particles efficiently.The coagulation principle is analyzed,and the collection performance is tested.The results show that the coagulation phenomenon of fine particle is very obvious,and the dipolar charging agglomeration coefficient is higher than that of coulomb agglomeration.Furthermore,the collection efficiency of dipolar charging electrostatic agglomerator is obviously higher than that of the conventional ESP for collecting fine particles under the same conditions.更多还原
