SIC DPF Honeycomb Ceramic Diesel Particulate Filter
Model Number：BS-SD
Place of Origin：Pingxiang,China
Keywords：sic dpf,sic diesel particulate filter,catalyst substrate
SiC Diesel particulate filter effectively remove particles and fumes from diesel engine exhaust emission. Its efficiency for carbon particulates filtration is more than 90%. So reduce the pollution to the enviroment. It would be a great help to solve theproblem of air pollution.

The particulate of emission is captured inside thin gas hole or entrance. As it lasts, the cumulated layer become thick, and pressure loss increase. To ensure the performance of engine, when pressure loss reaches some value, it is a must to recycle the filter. The recycle is making the particulate burning, by raising the gas temperature of filter.

Advantage
1. High filtration efficiency, high strength, strong resistance to thermal shock and mechanical vibration;
2. I have superior heat, corrosion resistance, and thermal conductivity;
3. The pore structure of SIC has better adjustability,
Filter materials with higher porosity and more uniform pore size distribution can be prepared;
After the airflow enters the DPF, due to the blockage of the outlet, the airflow flows out from the inner wall, forming a silicon carbide DPF carrier, which traps carbon smoke inside the DPF. The lifting mechanism of the silicon carbide DPF carrier plays a role in collecting carbon smoke, with a purification efficiency of over 90%. Finally, the collected carbon smoke is removed through regeneration and oxygenation combustion.
