Embodiment Construction

[0023] The structure of the metal-based diesel engine exhaust trap of the present invention is shown in Figure 1, which is a cylindrical block pressed by at least two kinds of metal alloy wires with different diameters and high temperature resistance above 1000 °C with different proportions. Its diameter is 60-200mm, its thickness is 3-20mm, and the top and bottom surfaces are plane. The above-mentioned metal alloy wire has a diameter of 0.05-0.4 mm, and FeCrAl alloy wire can be used. According to different engine conditions and fuel and diesel conditions, the ratio of metal wires with different diameters is different. The opening ratio of the trap is 70-80%. In order to promote the oxidation of the particles on the metal-based particle trap 4, the above-mentioned metal alloy wires may be coated with an oxidation catalyst. The oxidation catalyst is a rare earth-transition metal-noble metal composite oxidation catalyst, which can effectively reduce the ignition point of soot ...

Abstract

The invention involves the metal and the diesel engine exhaust particle trap, the exhaust treating plant and regenerates the method. The trap for at least gathers the cylindrical block by 2 kind of different diameters which the gold thread mix briquetting becomes, dies the diameter is 0.05~0.4mm, opens the porosity is 70~80%, filterability good, the cost is low. In this exhaust treating plant for alternates with the particle trap and the oxidation catalysis which is closely packed, trap namely above trap. At least some 1 metal and particle trap and 2 oxidation catalyses. Exhaust through when, partial particles and CO, HC in oxidation catalysis surface catalytic combustion, partial particles by trap interception. When oxidation catalysis elevation of temperature between trap elevation of temperature, above particle burning, realization automatic regeneration. The equipment effectively eliminates the diesel engine exhaust pollution, the automatic regeneration, guaranteed the necessary power performance is good, is suitable for the diesel car, the ship and so on. The regeneration method for joins the micro liquid catalyst in the diesel oil and uses this installment, further enhanced the installment efficiency and the regeneration effect.

Description

(1) Technical field [0001] The invention relates to a diesel engine exhaust particle filter, in particular to a metal-based diesel engine exhaust particle filter. [0002] The invention also relates to a diesel exhaust treatment device equipped with a metal-based diesel exhaust particulate filter. (2) Background technology [0003] Diesel engines are widely used in various power devices due to their good power, economy and durability, but the pollution caused by particulate matter in the exhaust of diesel engines has become a bottleneck restricting the further application of diesel engines. The control and treatment of diesel engine emissions include the capture of particulate matter and the purification of HC and CO. [0004] Particulate filter is currently the leading product of diesel engine exhaust treatment technology in the world. Since the 1980s, Germany, Europe, the United States and Japan have applied ceramic carrier filters to diesel engines in urban buses and so...
