摘要

对脉冲电晕脱除ＳＯ２、ＮＯｘ和粉尘的机理、规律，以及烟气各成分在脱除过程中的相互影响的研究结果表明，正脉冲电晕对ＳＯ２、ＮＯ的氧化脱除很有效，副产品可作肥料，除尘效果亦优于传统静电除尘器的直流供能方式；烟气中粉尘和气态成分之间存在良好的协同效应，促进了彼此的脱除。实验和分析肯定了使传统静电除尘器兼备烟气脱硫脱硝和除尘功能的可能性，并提出了实现方式，即采用同时施加纳秒级窄正脉冲高电压和直流偏压的供能方式，并通入氨作为添加剂。

Abstract

Based on the study of SO2

NOx and dust temoval mechsnisims and regularities by pulse corona

it is found that positive pulse corona is very effective for removing SO2 and NOx

the end product can be used as fertilizers

and the dust collection is also better than that by dc energization mode used in traditional ESP.There is a good synergistic effect between ash and gaseous components

which enhances the removal of each other. Results of experiments and analyses affirm the possibility to incorporate SO2

NOx and dust removal functions into one traditional ESP. The way to do that is to introduce the energization mode that exerts positive Pulse voltage and dc-bias voltage simutaneously.
