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.
The ceramic substrate is made of cordierite, and it is used for car catalytic converter. The cells density can be 100 cpsi, 300 cpsi, 400 cpsi or 600 cpsi. The shape will be round, oval or racetrack. We can supply both ceramic element coated with noble metals of Pt, Pd, Rh and ceramic element without noble metals.
Diesel particulate filter is used to remove black smoke (PM e. G.: Hydrocarbons, soot) from diesel engine exhaust, being a great contribution to the environment because of dealing with the exhaust from diesel engines. The diesel particulate filter can be used in different industrial fields such as environment protection, petrol-chemistry, medicine manufacture, and metallurgy etc. It has good investment return and broad prospect. The system installed DPF (Diesel Particulate Filter) been examined for urban bus, forklift, truck & mining constructing equipment.
For diesel engine tail gas purifying system, we manufacture catalyzed diesel particulate filters for removal of PM (soot), HC, CO and regeneration of soot. We can provide silicon carbide or cordierite diesel particulate filter, both catalyzed and un-catalyzed. We can according to engine types, gas analysis and emission requirements to design the catalyst project. We can also provide diesel oxidation catalyst (DOC) and three-way catalyst for all engine types.
After coated with catalysts, this product is applied in catalytic converter of diesel vehicle to catalyze, convert and purify the exhaust, making vehicle exhaust reaching standards of Euro IV and Euro V.
