Diesel Particulate Filter adopts structure of honeycomb. It sets up independent opening and blocking up passages in both ends and the waste gas enters from one open end, then goes through the porous beehive wall, and finally discharges from adjoining passage. The carbon particulates are left over on passage wall because they are too big to pass through wall hole and won't be discharged to air. Diesel Particulate Filter is a device designed to remove diesel particulate matter or soot from theexhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%. Some filters are single-use, intended for disposal and replacement once full of accumulated ash. Others are designed to burn off the accumulated particulate either passively through the use of a catalyst or by active means such as a fuel burner which heats the filter to soot combustion temperatures. This is accomplished by engine programming to run (when the filter is full) in a manner that elevates exhaust temperature or produces high amounts of NOx to oxidize the accumulated ash, or through other methods. Cleaning is also required as part of periodic maintenance, and it must be done carefully to avoid damaging the filter. Failure of fuel injectors or turbochargers resulting in contamination of the filter with raw diesel or engine oil can also necessitate cleaning. The regeneration process occurs at road speeds higher than can generally be attained on city streets; Vehicles driven exclusively at low speeds in urban traffic can require periodic trips at higher speeds to clean out the DPF.
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. The common types are ceramic based (cordierite or silicon carbide) and metallic based (stainless steel wire mesh) diesel particulate filter.
Diesel Particulate Filter working principle: It can reduce 96.5% carbon particulates emission by holding up the carbon particulates in tail gas of diesel at first, then clear up carbon particulates by means of electric heat, fuel burner etc., finally to meet carbon particulate emission standards.
Cordierite Diesel particulate filter:
Cordierite Diesel particulate filter adopt cordierite as its material. Its main compositions are SiO2, AL2O3 and MgO.
Sic-based Diesel Particulate Filter:
Sic-based Diesel Particulate Filter is a high-tech product. It is mainly used to produce new generation of diesel clean & emission system to fulfill the carbon particulate cleaning target of the EUIII, EUIV standards
