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 the cars equipped with diesel engines, because the exhaust gas of diesel engines contains black smoke particles, the existing exhaust filter can not effectively filter the black smoke particles, which will cause environmental pollution; the acidity of the existing exhaust gas The further elimination of components is a new demand for exhaust gas treatment and urban environmental protection

Abstract

The invention relates to a tail gas filter. The tail gas filter comprises a filter box (1). A purifier (2) and a ceramic honeycomb carrier (3) are arranged in the filter box (1). An atomizing spray head (8) is further arranged at the front end of the filter box (1). According to the tail gas filter, sodium carbonate water mist is firstly used for removing acidic components in tail gas, then the tail gas is subjected to two-stage filtration through the ceramic honeycomb carrier and the purifier, and the tail gas with main components of CO, HC and NOx is reacted into CO2, H2O, N2 and O2; and meanwhile, black smoke particles in the exhaust gas can be effectively filtered out through micropores in partition walls and can be combusted under the action of a catalyst coating, and 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 the cars equipped with diesel engines, because the exhaust gas of diesel engines contains black smoke particles, the existing exhaust filter can not effectively filter the black smoke particles, which will cause environmental pollution; the acidity of the existing exhaust gas The further elimination of components is the new demand of people for exhaust gas treatment and urban environmental protection. 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 f...
