In today’s era of rapid digital economy development, data centers have become the core infrastructure supporting social operation. As a key guarantee for the stable operation of data centers, diesel generator sets produce pollutants such as nitrogen oxides (NOₓ) and particulate matter (PM) during operation, and their environmental performance has long been facing severe challenges. With a decade of dedication to industrial exhaust gas treatment technology, Green Valley Environmental Protection has developed an integrated system combining a black smoke purifier (DPF) and a nitrogen oxide treatment system (SCR denitration) tailored for data center scenarios. This system achieves a dual balance between precise pollutant control and efficient generator set operation, injecting core impetus into the construction of green data centers.
DPF Particulate Filter – Precise Interception of Black Smoke Particulates (PM)
Green Valley Environmental Protection’s DPF/SCR denitration system adopts an integrated technical route of “particulate capture and selective catalytic reduction”, specifically addressing the two core pollution issues of particulate matter and nitrogen oxides to achieve emission compliance under all operating conditions. The independently developed water-washable and regenerable DPF by Green Valley Environmental Protection boasts a particulate capture efficiency of over 95% and a Ringelmann blackness grade of ≤1, far exceeding basic environmental protection requirements. Utilizing water-washable regeneration technology, it eliminates the need for high-frequency filter element replacement; ash accumulation can be removed simply through regular high-pressure air backwashing or water rinsing, significantly reducing maintenance costs and downtime. It is perfectly suited to the operational characteristics of data center backup generator sets, which remain on standby for long periods and start up in emergency situations.
SCR Denitration System – High-Efficiency Treatment of Nitrogen Oxides (NOₓ)
Green Valley Environmental Protection’s SCR denitration system uses urea aqueous solution as the reducing agent, combined with customized catalysts and intelligent control technology to achieve high-efficiency purification of nitrogen oxides. Under specific temperature conditions and with the action of catalysts, it undergoes a selective reduction reaction with NOₓ, converting it into harmless nitrogen (N₂) and water (H₂O). The denitration efficiency is stably maintained above 98%, and ammonia slip is controlled below 3ppm to avoid secondary pollution. The system is compatible with generator sets of different brands and power ratings, requiring no extensive modification of machine room space, and features convenient installation and maintenance.
Green Valley Environmental Protection’s DPF/SCR denitration system has been specially optimized for data center scenarios, demonstrating unique advantages in power adaptability, low-interference operation, and compliance assurance. It has been successfully applied in multiple large-scale data center projects, not only reducing the impact of pollutants on the surrounding environment but also enabling green, environmentally friendly and sustainable development, thus safeguarding the high-quality development of the digital economy. Green Valley Environmental Protection will continue to develop more efficient, energy-saving and intelligent exhaust gas treatment systems, helping data centers achieve green and low-carbon transformation while ensuring stable power supply.
