Wholesale Substrates Factories - DPF Diesel Particulate Filter Catalytic Converter – Hualian

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.

◎Low pressure drop;

◎Low thermal expansion coefficient;

◎High porosity ratio, pore diameter distribution uniform;

◎High temperature resistance, Good resistance to chemical corrosion;

◎Good heat shock resistance and heat vibration resistance;

◎High particulate trapping efficiency, adaptability to various modes of production.
