Problems solved by technology

[0002] At present, many ordinary automobile exhaust filters are directly discharged after simple filtration, and the exhaust gas of vehicles equipped with diesel engines contains black smoke particles. The existing exhaust filters cannot effectively filter black smoke particles, which will cause Environmental pollution; the existing tail gas silencer is realized by setting the silencer, but the silencer is easy to loosen and fall off, and it is difficult to achieve a good noise reduction effect

Abstract

The invention relates to a tail gas filter with a good black smoke filtering effect. The tail gas filter comprises a filtering tank (1). A first filtering net (2), a first ceramic honeycomb carrier (3), a second ceramic honeycomb carrier (7) and a second filtering net (8) are sequentially arranged in the filtering tank (1) in the air flow direction. A silencing pipe (10) is arranged in the filtering tank (1). Branch pipes (11) with holes formed in the walls are arranged on the silencing pipe (10). According to the tail gas filter with the good black smoke filtering effect, tail gas with main components being CO, HC and NOx is reacted into CO2, H2O, N2 and O2 under four-stage filtration of the first filtering net, the first ceramic honeycomb carrier, the second ceramic honeycomb carrier and the second filtering net, meanwhile, black smoke particles in waste gas can be effectively filtered out through micro holes in a partition wall, the black smoke particles can be burned up under the action of a catalyst coating, and the tail gas purification effect is further improved; and meanwhile the filter is good in silencing effect.

Description

technical field [0001] The invention relates to an exhaust filter with good black smoke filtering effect, which is used for purifying automobile exhaust. It belongs to the technical field of automobile equipment. Background technique [0002] At present, many ordinary automobile exhaust filters are directly discharged through simple filtration, and the exhaust gas of vehicles equipped with diesel engines contains black smoke particles, and the existing exhaust filters cannot effectively filter black smoke particles, which will cause Environmental pollution; Existing tail gas silencing is realized by setting silencing sheets, but the silencing sheets are easy to loosen and fall off, and it is difficult to achieve a better silencing effect. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, provides a kind of tail gas filter that black smoke filtering effect is good, this tail gas filter can also effectively fi...
