Diesel particulate filter is also called Diesel Particulate Filter (DPF). The main composition of
tail gas discharge from diesel is carbon particulates.
Cordierite Diesel particulate filter (DPF)
Cordierite Diesel particulate filter adopt cordierite as its material. Its main compositions are
SiO2,AL2O3 and MgO.
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.
Regeneration of filter: Burn the particulates by rising the gas temperature in filter to filtrate PM
which piled in the filter so as to guarantee the function of filter. The character of particulates in
exhaust gas of diesel relates to concentration of oxygen. It will burn in temperature of 550-650 °C.
Working principle of particulate filter: Plugging up two ends of porous beehive ceramic in turns
to filtrate PM by ceramic wall.
