Product Description

Diesel Particulate Filters are used in trap systems that remove particulate matter (soot) from diesel exhaust emissions. These filters have a cellular structure with individual channels open and pligged at opposite ends. Exhaust gases enter the open end, flow through the pores of the cell walls, and exit the filter through the adjacent channel. Sool particles are too large to flow
through the pores, and they collect on the channel walls. Periodically the filter is regenerated (heated) to consume the soot and clean the filter.

1.Large specific surface area: Ensure sufficient contact between exhaust gas and catalyst.
 

2.Stable water absorption performance: Ensure that the catalyst is firmly and evenly coated on the surface of the carrier, while not wasting due to excessive coating.
 

3.Warming-up performance: It is required that the temperature of the carrier can reach the active temperature of the target catalyst in a short period of time after the engine is started.
 

4.Low exhaust resistance: It is required that the carrier has minimal exhaust resistance to the engine, ensuring that it does not affect the performance of the engine.
 

5.High strength: As the working environment of the carrier is on bumpy cars, it is required that the carrier have high strength and not be damaged by external forces.
 

6.Good assembly: A component of the exhaust assembly of the carrier, only with a good appearance and size can assembly be ensured.

After collecting a certain amount of particles, it can lead to an increase in filter back pressure, a decrease in filtration efficiency, and a deterioration in the economy and power performance of diesel engine operation. Therefore, under certain conditions, DPF is regenerated to remove particles from the DPF. The regeneration of DPF includes active regeneration and passive regeneration.

Its disadvantages are difficulty in regeneration and high regeneration frequency. The thermal oxidation temperature of carbon particles can reach 825-875K, while the exhaust temperature of diesel engines is 450-675K. So it is necessary to add an external heat source (such as electric heating, microwave heating, etc.) or choose a highly active catalyst to reduce the oxidation temperature of carbon particles, so that the filtered carbon smoke particles are oxidized and removed for regeneration. However, the regeneration process can generate high temperatures above 2000 ºC, which can easily melt the ceramic carrier or cause local overheating and burning loss.
