Problems solved by technology

[0002] At present, ordinary automobile exhaust filters use catalysts to interact with NO and NO in automobile exhaust. 2 react with CO to form CO 2 and N 2 These two kinds of non-polluting gases, but cars equipped with diesel engines, because the exhaust gas of diesel engines contains black smoke particles, the existing exhaust filters cannot effectively filter black smoke particles, which will cause environmental pollution, and the existing honeycomb carrier cannot Effective acid resistance, resulting in short service life, unable to meet customer needs

Abstract

The invention relates to a tail gas filter which comprises a filter box (1); a purifier (2) and a ceramic honeycomb carrier (3) are arranged in the filter box (1; and the surface of honeycomb ceramicis coated with an acid-resistant coating. The tail gas purifier is good in acid resistance; through the two-stage filtration of the ceramic honeycomb carrier and the purifier, tail gas which mainly comprises the components of CO, HC and NOx reacts and thus CO2, H2O, N2 and O2 are produced; in addition, micropores in isolation walls can effectively filter soot particles in the tail gas, and the soot particles can be burnt off by the action of catalyst coatings, so that the tail gas purification effect is further improved.

Description

technical field [0001] The invention relates to an exhaust gas filter, which is used for purifying the exhaust gas of automobiles. It belongs to the technical field of automobile equipment. Background technique [0002] At present, ordinary automobile exhaust filters use catalysts to interact with NO and NO in automobile exhaust. 2 react with CO to form CO 2 and N 2 These two kinds of non-polluting gases, but cars equipped with diesel engines, because the exhaust gas of diesel engines contains black smoke particles, the existing exhaust filters cannot effectively filter black smoke particles, which will cause environmental pollution, and the existing honeycomb carriers cannot Effective acid resistance leads to short service life and cannot meet the needs of customers. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provides a kind of tail gas filter, this tail gas filter can also filter black smoke parti...
