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. Diesel particulate filter is made of Cordierite or Silicon Carbide. It adopts opening and blocking up passages in both ends and the exhaust gas flow through the porous beehive wall to filter particles.
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. Cordierite filter cores look like catalytic converter cores that have had alternate channels plugged the plugs force the exhaust gas flow through the wall and the particulate collects on the inlet face.
Features of the wall flow diesel particulate filter:
*Broad band filtration (the diameters of the filtered particles are 0.2-150 μ M)
*Low back pressure
*High filtration efficiency (can be up to 95%)
*High refractory
*High mechanical properties
