Under the goals of “carbon peaking and carbon neutrality”, straw biogas power generation has become an important form of effective utilization of biomass energy. Relying on the efficient use of resources, it has been widely promoted in scenarios such as agricultural production areas and breeding bases. During the combustion and power generation process of straw biogas, exhaust gases containing nitrogen oxides (NOₓ), particulate matter (PM), and other pollutants are produced. Without scientific treatment measures, these pollutants will not only lead to violations of environmental protection regulations, risking fines and production suspension, but also exacerbate air pollution, cause corrosion to power generation equipment, and restrict the sustainable development of the straw biogas power generation industry.
As environmental protection policies become increasingly stringent, some regions have introduced more rigorous local standards. Most traditional exhaust gas treatment equipment is designed for fixed operating conditions such as thermal power generation and industrial boilers, making it difficult to cope with the characteristics of straw biogas power generation exhaust gas, such as large fluctuations in composition and unstable operating conditions. Founded in 2015, Green Valley Environmental Protection (SGRUEN) focuses on the R&D, manufacturing, and engineering services of industrial waste gas treatment equipment. Its core businesses include SCR denitrification systems, diesel particulate filters (DPF), online reverse-blowing dry scrubbers, etc., with services covering diverse scenarios such as generator sets, industrial kilns, and data centers. After years of development, the company has built strong R&D and technical capabilities, accumulated a large amount of valuable treatment data in fields such as power plants, landfill gas generator sets, and biomass biogas power generation, and laid a solid technical and practical foundation for straw biogas exhaust gas treatment. The main component of straw biogas is methane (CH₄); however, the exhaust gas composition after combustion varies significantly due to different straw raw materials (such as corn stalks, wheat straw, rice straw, etc.), posing numerous challenges to treatment work.
To address the issues of straw biogas generator sets, such as complex exhaust gas composition, large fluctuations in emission concentration, and unstable operating conditions, Green Valley Environmental Protection has leveraged its core technologies to launch a customized integrated treatment solution combining DPF and SCR denitrification. This solution is compatible with generator sets of different power ranges from 50kW to 10MW, enabling NOₓ removal efficiency of ≥95% and PM removal efficiency of ≥95%, which fully meets national and local ultra-low emission requirements.
As environmental protection policies continue to tighten, some regions have implemented stricter local standards. Traditional treatment solutions are prone to emission non-compliance, putting enterprises at risk of production suspension for rectification. In response to the pollution characteristics and treatment pain points of straw biogas generator set exhaust gas, and based on the industry’s technical practices, Green Valley Environmental Protection adopts a comprehensive treatment approach combining DPF and SCR denitrification. Through modular design and an intelligent control system, the solution is adapted to generator sets of different power levels, achieving efficient removal of exhaust pollutants and stable compliance with emission standards. The appropriate solution is selected based on parameters such as exhaust gas temperature, pollutant concentration, and generator set power.
