摘　　要：介绍了新型DSC-M燃煤烟气干式超净技术,该技术通过循环流化床双段式吸收塔和超净布袋除尘器的有机结合,可实现脱硫、脱硝、除尘及多污染物协同治理,且没有废水产生、烟囱排烟温度高、烟囱无需防腐、排烟透明无视觉污染,真正实现燃煤烟气的超净排放要求。该技术已在包括20多台套300MW等级机组在内的上百台套燃煤机组上成功运用,并达到预期的超净排放目标,是新形势下烟气多污染物协同超净排放控制工艺的最佳可行技术之一。The paper introduces novel DSC-M coal-fred fue-gas dry ultra-clean technology. Based on the combination of a two-stage circulating fuidized bed absorber and an ultra-clean bag flter, the technology can achieve synergistic removal of SO2, NOx, PM2.5, and multi-pollutants. By using this technology, no wastewater is generated, exhaust fue gas temperature is high with no need of stake anticorrosion, and no visible plume is formed. The technology has been applied to more than 100 coalfred generating units, including more than 20 300MW-scale generating units, and realizes the ultraclean emission. DSC-M dry ultraclean technology is one of the best available technologies of fue gas multipollutants synergistic ultra-clean control under the new situation.
