Test Exploration of a New-type Flue Gas Purification Device for Denitrification and Carbon Removal

来自中华人民共和国生态环境部2017—2021年统计,SO_(2),NO_(2),CO的排放总量逐年减少,但每年减排比例也逐年降低,发展节能减排技术,深挖节能减排潜力,是节能减排工作的长期命题。新型脱硝除碳烟气净化装置独特的烟气净化技术,使催化剂能够在高温阶段(450~550℃),有效地与NO_(x),CO快速进行催化反应,使得NO_(x),CO能在较低的反应活化能垒下反应生成无害气体。为进一步加强对脱硝除碳技术的认识,挖掘市场推广潜质,将市场上广泛应用的仅有脱硝功能的烟气净化装置与新型脱硝除碳烟气净化装置进行类比试验,以烟气流量和喷氨量为独立变量,以烟气净化装置入口温度和反应面积为相关变量,以含氧量和瓦斯成分为约束条件,进行试验探究。探究成果有助于新型脱硝除碳烟气净化装置的市场推广,促进烟气净化技术推广和普及,为更好、更快实现节能减排与绿色发展提供支撑。

According to the statistics of Ministry of Ecology and Environment of the People's Republic of China from 2017 to 2021,the total emission of SO_(2),NO_(2)and CO was decreasing year by year,but the proportion of annual emission reduction was also decreasing year by year.It is a long-term proposition of energy conservation and emission reduction to develop energy conservation and emission reduction technologies and tap the potential of energy conservation and emission reduction.The unique flue gas purification technology of the new-type flue gas purification device for denitrification and carbon removal enables the catalyst to effectively conduct catalytic reaction with NO_(x)and CO in the high temperature stage(450-550℃),so that NO_(x)and CO can react to generate harmless gas under a low reaction activation energy barrier.In order to further strengthen the understanding of denitrification and carbon removal technology and tap the potential of market promotion,the flue gas purification device with only denitrification function widely used in the market was compared with the new-type flue gas purification device for denitrification and carbon removal.The test was conducted with flue gas flow and ammonia injection as independent variables,flue gas purification device inlet temperature and reaction area as related variables,and oxygen content and gas composition as constraints.The research results will contribute to the market promotion of the new-type flue gas purification device for denitrification and carbon removal,promote the promotion and popularization of flue gas purification technology,and provide support for better and faster realization of energy conservation,emission reduction and green development.
