With the development of economic globalization and the enhancement of people’s awareness of environmental protection, the generator set as an important energy supply equipment, its exhaust emissions are increasingly valued by all walks of life.
As an indispensable power supply equipment in the industrial and civil fields, the exhaust gas generated during its operation has a serious impact on the environment. The exhaust contains a variety of harmful substances, which pose a threat to human health and the ecological environment, such as nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter (PM), etc. These substances pose a threat to human health and the ecological environment, therefore, the effective purification of the exhaust gas of the generator set not only responds to the needs of environmental protection policies, but also an important measure to improve equipment performance and extend service life.
Generator group tail gas aftertreatment: mainly divided into physical method, chemical method and biological method.
1, exhaust gas treatment and purification equipment
1.1 Green Valley environmental protection of black smoke purifier
The black smoke purification equipment can remove the black smoke and PM particles in the exhaust gas of the diesel engine. The metal felt filter material made of 316L alloy metal wire imported from France is used. According to the characteristics of the exhaust gas of the internal combustion engine, the DPF filter carrier with modular and customized design and professional fluid mechanics design is used to effectively remove the particles in the exhaust gas.
1.2 Select catalytic reduction SCR denitration system
SCR denitrification system is an efficient nitrogen oxide emission reduction technology. Under the action of catalysts, NOx is reduced to nitrogen and water. SCR reaction is a complex and diversified catalytic reduction reaction, the main reactions are as follows:
NH₃·H₂O→NH₃↑+H₂O (Urea hydrolysis reaction)
NO+NO₂+2NH₃→2N₂↑+3H₂O (nitrogen oxide reduction reaction)
4NO+O₂+4NH₃→4N₂↑+6H₂O (Nitric oxide reduction reaction)
2NO₂+O₂+4NH₃→3N₂↑+6H₂O (nitrogen dioxide reduction reaction)
Although the exhaust gas aftertreatment technology has made remarkable progress, it still faces challenges such as high cost, complex equipment and difficult maintenance, and the cost can be effectively reduced through technological innovation and system integration. Simplify the operation process and improve the reliability and stability of the equipment. Our SCR denitrification system can meet the national environmental protection requirements, ultra-low nitrogen oxide emissions and ammonia escape requirements of less than 3ppm, with a strong comprehensive competitiveness. The patented mixing technology ensures that ammonia and flue gas are fully mixed to achieve near-zero nitrogen oxide emissions.
Our company is committed to providing economic and effective overall solutions for environmental pollution prevention and control of various industrial enterprises, and has become a market influential overall solution provider for industrial pollution control, and can provide one-stop environmental protection solutions for customers’ safe production and standard emissions. The post-treatment and purification technology of generator tail gas is the key to achieve clean energy production. With the continuous progress of technology and the promotion of policies, the future generator set will be more environmentally friendly and efficient.
