Product Description

SiC-based Diesel particulate filter is used to remove black smoke from diesel engine exhaust. DPF can be widely used in different industrial fields such as transportation, generating units, engineering machinery and metallurgy etc. The system installed Diesel Particulate Filter been examined for urban bus, forklift, truck & mining constructing equipment.

Silicon carbide Diesel Particulate Filter is mainly used in the diesel engine tail gas purifying system to solve the air pollution problem. It adopt opening and blocking up passages in both ends and the exhaust gas flow through the porous beehive wall to filter particles.
The characteristics of the wall flow diesel particulate filter as follows:
*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

If the DPF is coated with precious-metal (such as Pt, Pd and Rh), black smoke with carbon particulate from diesel engine pass through a special tube and enter the filter. The carbon smoke particulate is absorbed to the filter made of metallic fiber felt, when passing the inner dense set and bag-style filter. When particulate absorption reaches some degree, the tail burner would be ignited to burn automatically. In this case, the particulate absorbed been burned out and turned into nontoxic CO2 then discharge. The full device is designed as double room structure, and filtration and recycle are going in different areas, making them non-disturbed. The system can work automatically whatever working condition the engine in. Especially made honeycomb ceramic particulate filter, acts as capturing device to the particulate to some extent.
