Diesel exhaust treatment device can reduce emissions by 95%

Recently, Hefei University of Technology has successfully developed the diesel engine exhaust device - diesel engine particulate matter capture system DPF, which can remove particulate matter (PM2.
5) in diesel engine exhaust emissions with remarkable results, can reduce diesel vehicle pollutant emissions by more than 95%, and overcome the problem
of urban diesel vehicle exhaust emission pollution.

The project uses the active regeneration technology DPF system, through the modification of the diesel engine exhaust system, the wall flow filter channel carrier is made of specific materials, the particulate matter of the exhaust gas is filtered, and when the particulate matter in the trap is filled to a set level, the captured particulate matter is oxidized through a specially designed regeneration equipment to generate carbon dioxide and discharge
.
The trap can be recycled all
the time.
After adopting this device, the black smoke of diesel engine exhaust disappears and the noise is reduced
.

China is a major producer of diesel engines and diesel vehicles, and particulate matter emissions are large
.
The use of this technology device can reduce the pollutant emissions of diesel vehicles by more than 95%, and has automatic regeneration control function
.
The device has no quality requirements for fuel, and it is also convenient
to use and maintain.
At present, the device has been applied in Changchai, Anhui Fuyang City Bus Company and Chizhou Bus Company in China, and the effect is good
.
According to estimates, only the use of this technical device for emission purification transformation in buses in Anhui Province can reduce particulate matter emissions by nearly 1,000 tons
per year.
