锅炉烟气脱硫脱硝超低排放改造项目技术方案选择及应用

Technical Scheme Selection and Application of Boiler Flue Gas Desulfurization and Denitration Ultra-low Emission Transformation Project

随着国家环保标准的不断提高,需要对现有供汽锅炉烟气进行脱硫脱硝超低排放改造。通过对项目改造方案比选,最终确定采用SCR脱硝+SDS干法脱硫+布袋除尘器的工艺路线。改造实施后,对项目试运行中出现的问题进行了优化改造,使脱硫脱硝装置达到了预期效果。

With the continuous improvement of national environmental protection standards,it is necessary to carry out ultra-low emission transformation of desulfurization and denitration of flue gas from existing steam supply boilers.Through comparison and selection of project transformation schemes,the process route of SCR denitration+SDS dry desulfurization+bag filter is finally determined.After the implementation of the transformation,the problems occurred in the trial operation of the project were optimized and transformed,so that the desulfurization and denitration device achieved the expected effect.
