Honeycomb ceramic substrate DPF cleaning diesel particular filter for diesel exhaust gas purifier

Diesel Particulate Filter (DPF)

Diesel particulate filter (DPF) is also called wall flow filter, whose materials are cordierite or silicon carbide. It adopt opening and blocking up passages in both ends and the exhaust gas flow through the porous beehive wall to filter particles, can effectively remove particulate matter(PM) and soot from diesel engine exhaust emission, its efficiency for carbon particulates filtration is more than 90%.

Diesel particulate filter can be widely used in different industrial fields such as transportation, generating units, engineering machinery and metallurgy etc. The system installed diesel particulate filter been examined for urban bus, forklift, truck & mining constructing equipment.

Advantage of diesel particulate filter

1. Low pressure drop.
2. Low coefficient of thermal expansion.

3. Good thermal shock resistance.

4. High temperature resistance, good resistance to chemical corrosion.

5. High porosity, pore size distribution uniform, high filter specific surface area.

6. Long-term durability performance.

7. High particulate trapping efficiency, suitable for all kinds of regeneration.

Cordierite Diesel Particulate Filter(DPF)

The most common filter is made of cordierite. Cordierite filters provide excellent filtration efficiency, are relatively inexpensive (comparison with Sic wall flow filter). The major drawback is that cordierite has a relatively low melting point.

Silicon Carbide Diesel Particulate Filter(DPF)

Silicon carbide diesel particulate filters (Sic wall flow filters) have a higher melting point and filtration efficiency (can be up to 95%) than cordierite, they are usually more expensive than cordierite wall flow filters.
