Recently, Hefei University of Technology successfully developed diesel engine particulate trapping system DPF, which can remove particulate matter (PM2.5) from diesel exhaust emissions. It has achieved remarkable results, and overcomes the problem of urban diesel vehicle exhaust pollution.
The project uses the active regeneration technology DPF system to modify the exhaust system of the diesel engine and use a specific material to form a wall-flow filter channel carrier to filter and trap the particulate matter of the exhaust gas. When the particulate matter in the trap is filled to a set level Afterwards, the specially-designed regenerative equipment oxidizes the trapped particulate matter and generates carbon dioxide. The trap can be recycled. With this technical device, the black smoke of the diesel exhaust disappears and the noise is reduced.
China is a major producer of diesel engines and diesel vehicles. The amount of PM emitted is large. According to calculations, in 2011, it was 621,000 tons, of which diesel particulates accounted for 85.4% of the total emissions, and serious air pollution. People often saw that when a diesel car was driven, especially when it was started and accelerated, a stock of black smoke erupted and people covered their noses. Over. With this technical device, it is possible to reduce the emissions of diesel vehicles by more than 95%, and to have automatic regeneration control. With this technical device, there is no quality requirement for fuel, and the use of maintenance is also very convenient. At present, the technology device is applied in China's Changchai, Anhui Fuyang Bus Company, and Chizhou Bus Company, and the effect is good. It will soon be promoted in bus companies in Hefei and other cities. According to calculations, only buses in Anhui Province adopt this technical device for emission purification and reduction, which can reduce particulate emissions by nearly 1,000 tons per year.
Hefei University of Technology, as a national key science and engineering college, has strong research and development capabilities. The school proposes and follows the "paper written on the product, research done in the project, the results used in the enterprise," actively carry out production and research, conduct practical research for enterprises and society, and achieved a large number of results. The successful development of the diesel particulate collection system fills the gap in this field in China, and is of great significance to China's environmental protection, especially the treatment of air pollution.
