Under the guidance of the “dual carbon” goal, data centers, as high-energy critical infrastructure, not only need to ensure stable power supply, but also need to meet environmental standards. A data center in Shenzhen is facing environmental compliance pressure due to excessive emissions of nitrogen oxides (NOx) from backup generator sets. Green Valley Environmental Protection has successfully completed low nitrogen transformation for the MTU generator set of the data center with mature exhaust treatment technology, providing support for the green operation of the data center.
1、 Project Background
The generator set of a data center in Shenzhen serves as the core backup power source for the power grid during key periods. The exhaust gas generated during the operation of the diesel engine contains various harmful substances (NOx, CO, hydrocarbons, soot particles, etc.), and environmental protection measures are urgently needed. Green Valley Environmental Protection, with its profound technical accumulation in the field of generator sets, has tailored exhaust gas treatment plans for it and provided full process services from design, equipment production and research and development to commissioning.
2、 Core parameters of the project
- Brand and model: MTU 20V4000G23
- Displacement: 95L
- Quantity: 1 unit
- Main power: 2000KW
- Backup power: 2200KW
- Original NOx emissions: 3456mg/m3N
- Target emissions: 120mg/m3N
- Fuel type: diesel
3、 Core governance technologies
- Solution: SCR denitrification – precise injection of urea, reducing NOx to harmless nitrogen N2 and water H2O, with a denitrification efficiency of over 90%
- Intelligent control system: capable of remote control of the system, real-time adjustment of urea metering, ensuring stable and efficient operation
4、 Project Highlights
- High power adaptation: specially designed for 2000KW power generation units, suitable for long-term stable operation at full load
- Low back pressure optimization: The exhaust outlet has low back pressure, which does not affect engine performance
- Low noise design: operation meets noise standards, installation is environmentally friendly
- Flexible layout: Optimize installation positions to complete lifting and maintenance according to different application scenarios, making it easy to maintain.
Long lasting durability: stainless steel anti-corrosion shell, continuous operation ability, long service life
Zero second pollution: no derivative pollutants in the treatment process, ultra-low emissions and ammonia escape less than 3ppm
This cooperation not only demonstrates the technical strength of Green Valley Environmental Protection in the field of denitrification of power generation units, but also confirms the advantages of the customized solution+full process service model. In the future, Green Valley Environmental Protection will continue to deeply cultivate the field of industrial exhaust gas treatment, providing more efficient, economical, and stable environmental protection solutions for enterprises, and helping to achieve the “dual carbon” goal.
