Superior Quality Diesel Particulate Filter DPF Catalytic Converter

Diesel Particulate Filter of emission is captured inside thin gas hole or entrance. As it lasts, the cumulated layer become thick, and pressure loss increase. To ensure the performance of engine, when pressure loss reaches some value, it is a must to recycle the filter. The recycle is making the particulate burning, by raising the gas temperature of filter. Diesel Particulate Filter is related to the oxygen concentration. It is burning at 550-650, its adopted to raise emission temperature by adjusting throttle, and increase gas temperature with burner. The particulate burning temperature can be decreased by catalyzed, making cumulative particulate burning as soon as possible, thus recover the pressure loss and fitters performance, then the filter is recycled.



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.

Applications:
*As support of catalyst, ceramic honeycomb materials are typically used for purifying automotive emission, removing bad smell etc
*As heat exchange media, ceramic honeycomb materials are mainly utilized in heat recovery unit of RTO's instead of ceramic saddles
*As filtrate substrate, ceramic honeycomb materials are generally utilized in food processing, water treatment, environmental industry, metallurgical industry etc
*Used to remove black smoke (PM eg: Hydrocarbons, soot) from diesel engine exhaust, being a great contribution to the environment because of dealing with the exhaust from diesel engines, therefore, it will attract much attention from car manufacturers

Characteristics:
*Low thermal expansion
*High filter specific surface area
*Long-term durability performance
*High soot sremoval: >95.4%
*Broad band filtration (the diameters of the filtered particles are 0.2-150 µ M)
*Low back pressure
*High filtration efficiency (can be up to70%-95%)
*High refractory
*High mechanical property
