Production Process<\/h3><\/div>\n- Selective Catalytic Reduction (SCR) Denitrification Technology \u2013 organized emission treatment, meeting national environmental emission standards<\/li>\n
- SCR technology can be widely used in high-temperature combustion or chemical reaction processes in energy, metallurgy, chemical industry, transportation, waste incineration, building materials and other industries, such as coal-fired, biogas, natural gas, biomass boilers, and diesel engines, waste incinerators and other waste gas denitrification treatment<\/li>\n<\/ul>\n<\/div>
Current Issues<\/h3><\/div>\n- Globally, NOx emission limits are gradually tightened (such as China’s ultra-low emission requirements of NOx\u226450 mg\/Nm\u00b3), and waste gas does not have supporting denitrification treatment environmental protection facilities, or traditional denitrification processes (such as SNCR) cannot meet the standards, affecting corporate production, brand value and social responsibility evaluation<\/li>\n<\/ul>\n<\/div>
Improvement Methods<\/h3><\/div>\n- Use selective catalyst reduction (SCR) denitrification technology to treat waste gas to reduce air pollutant emissions<\/li>\n<\/ul>\n<\/div>
Technical Introduction<\/h3><\/div>\n- Selective catalytic reduction (SCR) is an advanced technology for efficient control of nitrogen oxide (NO\u2093) emissions, widely used in power, metallurgy, chemical industry and transportation and other fields. The core principle is to selectively react the reducing agent (ammonia or urea) with NO\u2093 in the flue gas under the action of a catalyst to generate harmless nitrogen (N\u2082) and water (H\u2082O), thereby achieving the denitrification goal.<\/li>\n
- In the SCR reactor, NH\u2083 and NO\u2093 undergo a redox reaction on the catalyst surface, and the reaction temperature usually needs to be controlled at 280\u2013400\u00b0C. The typical reaction formula is: 4NO+4NH3+O2\u2192(catalyst)4N2+6H2O<\/li>\n<\/ul>\n<\/div>
Key Benefits<\/h3><\/div>\n- Efficient denitrification: The denitrification efficiency can reach 80%~95%, meeting the ultra-low emission (NO\u2093\u226450 mg\/Nm\u00b3) requirements.<\/li>\n
- Strong adaptability: It can handle a variety of high NO\u2093 flue gases such as coal, gas, and garbage incineration, and is suitable for different industrial scenarios.<\/li>\n
- Collaborative governance: Integrate with dust removal and desulfurization systems to achieve collaborative control of multiple pollutants.<\/li>\n<\/ul>\n<\/div>
