Silicon Carbide Diesel Particulate Filter (DPF)
Diesel particulate filter (DPF) is also called wall flow filter. Spreading with catalyst layer is called CDPF (catalytic DPF).
The filtration material researched and used at present is of three types: ceramic, metallic and composite based. The common types are ceramic based (cordierite or silicon carbide) and metallic based (stainless steel wire mesh) diesel particulate filter.
The main composition of tail gas discharge from diesel is carbon particulates. Diesel particulate filter is a setting to reduce emission granule by filtrating which is set in exhaust system in diesel. Its efficiency for carbon particulates filtration is more than 90%. Part of dissoluble organic composition (SOF) (especially high boiling point) may be trapped.
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.
Feature & Advantages
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.
Diesel particulate filter is suitable for exhaust gas purification of various kinds of diesel vehicles and ships. We can produce different materials of DPF: cordierite diesel particulate filter and silicon carbide diesel particulate filter.
