In the power supply sector, diesel and gas generators—critical backup or primary power sources—have seen their exhaust emissions become a growing concern. Harmful pollutants like nitrogen oxides (NOx) and particulate matter (PM) not only pollute the environment but also challenge companies’ compliance with operational standards. Green Valley Environmental Protection offers an efficient and reliable solution to this challenge through its core SCR denitrification system and DPF particulate capture technology.
Industrial power equipment poses significant challenges through exhaust emissions during operation. When gas turbines and generator sets operate at full capacity, nitrogen oxide (NOx) concentrations frequently exceed environmental standards. Conventional treatment technologies often suffer from low-temperature inactivation, high ammonia slip rates, and incomplete particulate matter capture, resulting in high maintenance costs and secondary pollution risks. Particularly in facilities requiring continuous power supply such as data centers, hospitals, airports, and oil fields, backup generators often emit substantial black smoke during startup, directly impacting regional air quality and equipment safety.
Green Valley Environmental Protection’s exhaust gas treatment solution for generators, centered on an intelligent SCR denitrification system and a high-efficiency DPF particulate filter, delivers a comprehensive and reliable management approach.
DPF particle collector: a powerful tool for black smoke control
Green Valley Environmental’s GRVNES-CYJ series particulate filters are an innovative dry exhaust purification system for heavy-duty diesel engines, developed in-house. Featuring 316L alloy metal wires imported from France, these filters demonstrate exceptional heat and corrosion resistance, specifically engineered for the high-temperature exhaust of generators. The system employs multiple DPF carrier units with snap-fit detachable modules, enabling water-based regeneration for easy maintenance. With a black smoke treatment efficiency of 90%-98%, it effectively reduces emissions to below the 1st Ringelmann Blackness level (15mg/Nm³).
SCR denitrification system: Precise control of NOx emissions
Green Valley Environmental’s SCR denitrification system employs urea solution injection into exhaust gases. Under specific temperature and catalyst conditions, it reduces NOx to nitrogen and water. The system features precision metering technology that intelligently adjusts urea injection rates based on load variations, ensuring stable compliance with emission standards. Utilizing ammonia slip control technology, it maintains ammonia slip below 3ppm to prevent secondary pollution.
Green Valley Environmental Protection’s exhaust gas treatment technology for generators boasts multiple standout advantages that set it apart in the industry. The modular integrated design is a key highlight of Green Valley’s solution. The equipment can be directly connected to the generator set’s existing exhaust pipes, eliminating the need for structural modifications to the engine room and significantly reducing installation complexity and costs. The intelligent monitoring system enables precise management of exhaust gas treatment. Sensors continuously monitor parameters such as NOx concentration, temperature, and flow rate in the exhaust gas. When data is transmitted to the control system, it automatically adjusts urea injection amounts to ensure stable and efficient operation. The low-maintenance design further reduces operational costs.
Green Valley Environmental Protection’s exhaust gas treatment solutions have been successfully implemented across multiple key sectors, accumulating extensive practical experience. For a Shanghai-based intelligent computing center, the company provided an SCR denitrification system for 24 power generation units, achieving dual breakthroughs in exhaust gas treatment and energy conservation. A power plant in Sichuan adopted Green Valley’s denitrification equipment, reducing NOx emissions from 1200mg/Nm³ to below 50mg/Nm³—a decrease exceeding 95%. The SCR system also empowered denitrification for oilfield associated gas power generation units, driving efficient energy utilization and clean energy conversion.
As global environmental policies continue to tighten, exhaust gas treatment for generators has become a critical challenge for numerous industries. Green Valley Environmental Protection’s metal DPF particle traps and intelligent SCR denitrification systems have been validated in multiple key domestic projects, demonstrating remarkable treatment effectiveness. Moving forward, Green Valley Environmental Protection will continue to focus on technological innovation, advancing exhaust gas treatment from “passive emission reduction” to “resource regeneration + intelligent integrated control”. This evolution will provide more viable solutions for the industry’s green transformation.
