摘要

针对燃煤机组超低排放改造中技术路线上存在的争议问题

结合国内超低排放改造可行性研究及协同脱除改造工程的实施

总结了烟气污染物协同脱除技术的发展现状

重点介绍了超低排放协同脱除策略及一体化脱除核心技术

提出超低排放改造可结合"协同"和"湿除"2条技术路线

在确定的边界条件和场地布置前提下优化设计。工程应用表明

燃煤机组采用协同脱除技术实施超低排放改造后

NO_x、SO_2及烟尘排放质量浓度均优于超低排放限值要求

同时对SO_3、Hg和PM_(2.5)等污染物的脱除效果显著。

Abstract

In view of the controversial issues in the technical route of the ultra-low emission transformation of coal-fired units

this paper summarizes the development of flue gas pollutant synergistic removal technology

combing with the feasibility study of the ultra-low emission transformation and the implementation of the integrated renovation project. The ultra-low emission synergistic removal strategy and the integration of the core technology were presented in detail. It points out that the ultra-low emission transformation can combine the "synergistic" and "wet removal" routes

and the overall optimization design can be carried out in the premise of certain boundary conditions and site layout full. The engineering application shows that

after the coal-fired unit adopted the integrated synergistic removal technology

the concentration of NOx

SO2 and soot were all below the ultra-low emission limit. At the same time

the removal effect of pollutants such as SO3

Hg and PM2.5 was also remarkable
