摘要
大气颗粒物特别是超细颗粒物PM2.5对人体健康及环境会产生很大危害,燃煤电厂是超细颗粒物的重要排放源。本文简要阐述了燃煤电厂超细颗粒物排放的现状,并针对燃煤电厂重点介绍了超细颗粒物的排放控制技术,包括传统的除尘器加湿法脱硫设施的除尘、混合除尘控制技术、以及在传统除尘器前设置团聚预处理装置的技术等。指出了各种技术的利弊、应用现状及应用前景展望。
The atmospheric particles, especially ultra fine particulate matter PM2.5 will pro- duce great harm on human health and the environment, coal-fired power plants is an impor- tant fine particulate matter emission sources. This paper describes the status of coal-fired power plants emissions of ultra fine particles, and highlights for the coal-fired power plant e- missions of fine particulate matter control technologies, including traditional wet desulphurization facilities, plus ESP dust, mixed dust control technology, and set the reuniting pretreatment device before conventional fiher, etc. Pointed out the pros and cons of various technolo- gies, application status and prospect for application.
