AI Technical Summary

Problems solved by technology

Ceramic materials have the disadvantages of poor thermal conductivity and poor resistance to mechanical vibration that are difficult to overcome.
In recent years, there have also been researches on the use of foam alloys as filter materials. Although they can meet the requirements, the cost is high and it is difficult to realize industrialization.

Embodiment Construction

[0010] figure 1 Shown is a schematic structural diagram of an axial cylindrical diesel vehicle exhaust particulate filter device. The device is connected to the two ends of the shell 3 by the inlet cone 1 and the exhaust cone 4, and the 3-6 composite metal base mesh panels 2 installed in the shell are mechanically fixed on the inner wall of the shell 3, and each filter layer is composed of 4 - Composed of 16 layers of metal mesh panels. The number of layers of the metal mesh plate and the number of channels of the composite metal base mesh plate 2 can be adjusted according to the exhaust volume of the diesel engine. The gas exhausted by the engine enters the inner cylinder of the shell 3 from the cone cylinder 1, passes through the composite metal-based mesh plate 2 in turn, and is filtered by the metal composite mesh plate or other types of metal-based composite filter materials, and the particulate matter in the exhaust gas is captured. On the composite screen, the filtere...

Abstract

An axial cylinder shaped diesel vehicle exhaustion particles filtering apparatus made of composite metal base net plates, wherein the air intake conical cartridge and the exhaust conical cartridge are connected to the two ends of the casing, the composite metal base net plates are mounted on the inner wall of the outer casing, the exhaust filtration is achieved by the composite metal base net plates which collect the engine exhaust particles on the filtration element and prevent them from entering the atmosphere, thus effectively cleaning the particles in the diesel engine exhaust.

Description

Technical field: [0001] The invention belongs to the scope of vehicle tail gas purification equipment, in particular to an axial cylindrical diesel vehicle exhaust particulate filter device made of a composite metal base net plate for diesel vehicle exhaust purification. Background technique: [0002] Although the diesel engine came out later than the gasoline engine, it is widely used in various power devices due to its good power, economy and durability. However, the pollution caused by the exhaust particulate emission of the diesel engine has become a bottleneck restricting the further application of the diesel engine. At present, the diesel particulate filter (diesel particulate filter) is recognized as an effective after-treatment technology, which focuses on the treatment of the formed particles, and gathers the particles in the exhaust of the diesel engine in the filter by means of interception and deposition. When the particles accumulate to a certain extent, they ar...
