Study on Synergistic Removal Characteristics of Multiple Pollutants in Domestic Waste Incineration Plant by Integrated Flue Gas Purification Process
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,NO,,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 2.405 1 million yuan per year.
