摘　　要：一体化烟气净化工艺是以触媒陶瓷滤管为核心的一种新型烟气处理方式,可实现粉尘、酸性气体、NOx及二口恶英等多种污染物高效协同脱除。在浙江某生活垃圾焚烧厂进行了中试试验,以验证该工艺脱硝、除尘及二口恶英脱除效果和摸索关键技术参数,并着重分析了生活垃圾焚烧烟气中二口恶英的指纹特性及再生情况。研究结果表明:当反应温度为210~220℃、陶瓷滤管过滤风速为0.60 m/min时,除尘、脱硝、脱二口恶英效率最高分别为99.87%、94.28%、95.68%,可满足欧盟2010排放指标。经济测算表明,烟气达超净排放标准时,与常规烟气净化六步法工艺相比,750 t/d垃圾焚烧线采用一体化工艺投资运行成本每年至少可节省240.51万元。The integrated flue gas purification process is a new flue gas treatment method with catalyst ceramic fiber filter tube as the core,which could achieve efficient collaborative removal of dust,acid gas,NOx,dioxins and other pollutants.A pilot test was conducted in a domestic waste incineration plant in Zhejiang province to verify the effect of denitrification,dust removal and dioxins removal process and explore the key technical parameters.The fingerprint characteristics and regeneration of dioxins in domestic waste incineration smoke was emphatically analyzed.The results showed that when the reaction temperature was from 210℃to 220℃,the filter wind speed was 0.60 m/min,the highest efficiency of dust removal,denitrification and dioxin removal were 99.87%,94.28%and 95.68%,respectively,which could meet the EU 2010 emission targets.The economic calculation showed that when the flue gas reached the ultra-net emission standard,compared with the conventional six-step process of flue gas purification,the investment and operating cost of 750 t/d waste incineration line using the integrated process could save at least 2.4051 million yuan per year.
