With the advancement of the “East Calculation West Calculation” project, people’s demand for backup power has increased. The first phase of a smart computing center in Shanghai is equipped with 24 Weichai 2M55D2450E310 series diesel generator sets as backup power. Under the “dual carbon” target, the current situation of traditional diesel engine NOx emissions reaching 2550mg/Nm ³ not only faces the strict requirements of the “Fixed Internal Combustion Engine Air Pollutant Emission Standards” (DB34/3559-2019), but also conflicts with the green goals pursued by the intelligent computing center. Green Valley Environmental Protection Innovation adopts SCR system to achieve dual breakthroughs in exhaust gas treatment and energy conservation and consumption reduction.
The Green Valley Environmental Protection SCR Denitrification System (Selective Catalytic Reduction) converts harmful nitrogen oxides NOx into harmless nitrogen and water, efficiently removing them with a removal rate of 95%. The emission concentration can be reduced to 50mg/Nm ³, and ammonia escape is ≤ 3ppm, which is better than the national standard. Green Valley Environmental Protection also has a wealth of successful experience in the heat treatment industries such as data and computing centers, steel, metallurgy, finance, hotels, airports, and industrial furnaces. It can provide one-on-one customized design solutions for complex application scenarios to meet the ultra-low emission requirements of nitrogen oxides in different scenarios and regions. Green Valley Environmental Protection has achieved compact structural design, intelligence, precise spraying, early warning, data collection and management, remote control, online transmission and other functions in the field of ultra-low nitrogen oxide emissions, ensuring that ammonia escape data is less than, and has strong comprehensive competitiveness.
Project: Exhaust gas denitrification of backup generator set in a smart computing center in Shanghai
Brand and model: Weichai 12M55D2450E310 * 24 units
Matching type: SCR denitration
Displacement: 65.65L
Model: GRVNEC100-TX-24
NOx decreased from 2550mg/m3N to 150mg/m3
The SCR denitrification system of Green Valley Environmental Protection has patented mixing technology, which can ensure sufficient mixing of ammonia and flue gas, thereby achieving near zero emissions of nitrogen oxides; Through precise metering injection technology, stable and compliant emissions can be achieved under changing load conditions. Combined with closed-loop and open-loop control, modular packaging technology ensures the airtightness of the reactor, and IoT technology is used to achieve multi terminal and remote monitoring. In the face of the dual carbon era, Green Valley Environmental Protection will continue to be driven by technological innovation, work together with global generator manufacturers, and inject green momentum into the development of global data centers, computing power centers, industrial enterprises, and different industries.
