Diesel Particulate Filter Catalytic Converter for Cummins 750 kVA Diesel Generator Genset
Diesel Particulate Filters (DPF) utilize cordierite wall-flow monoliths to trap the soot produced by medium to heavy-duty engines in off-road, on-road andstationaryapplications. The cylindrical filter element consists of many square parallel channels running in the axial direction, separated by thin porous walls, as shown below.
The channels are open at one end and plugged at the other, which forces the particle laden exhaust gases to flow through the walls. Gas is able to escape through the pores in the wall material. Particulates, however, are too large to escape and are trapped in the filter walls and in the inlet channels. A proprietary noble metal catalyst is coated onto the inside surface of the filter monolith.
The catalyst lowers the soot combustion temperature allowing the filter to regenerate. The accumulated soot is oxidized in the filter during regular operation of the engine. For about 25-30% of the engine operating time, the exhaust temperatures must be at least 275-300°C for proper filter regeneration when ULSD (ultra-low sulfur diesel) fuel is used.
Catalytic Diesel Particulate Filter Soot Filter for Diesel Generator Setadapts the diesel particulate filter (DPF) as the core components. This kind of treatment make the black smoke purification rate can be up to 90%-98%. Besides ,the use of the most advanced catalyst continuously regenerating technology can make the capture of particulate matters(PM) completely automatic combustion, and effectively remove CO,HC and other harmful gases, without adding any more pollution.
Diesel oxidation catalyst(DOC) also as the core components of exhaust gases filtration system, it can promote chemical oxidation of CO and HC as well as the SOF portion of diesel particulates.We also supplyCatalytic Converter, Catalytic muffler, Motorcycle catalytic converter, DOC Catalyst, Diesel Particulate Filters, DPF, SCR catalyst ,Ceramic honeycomb monolith , Metal honeycomb carrier, ect. Ourmanagement system has been certified the ISO9001 and TS16949 by SGS company.
Combine the catalyzed pre-filter(DOC) with the wall flow filter(DPF), can help to reduce the harmful gas such as HC, CO.. The working principle as follows:
