Automobile tail gas cleaner device

Abstract

The invention relates to an automobile tail gas cleaner device. The device comprises two tail gas purifiers and a silencer connected between the two tail gas purifiers; and each tail gas purifier comprises a purifier shell and a filter block arranged in the purifier shell, wherein the filter block is a Cu-Ca-based consolidated type filter block, and the filter block is in a honeycomb mesh structure. According to the device, compared with the prior art, the silencer and the tail gas purifiers are connected in series at intervals, so that the high conversion rate filtration of tail gas is completed while silencing effect is realized, and the harmless discharge of the automobile tail gas is realized; and the tail gas purifiers have the functions of ash discharge and drainage, so that the discharge of ash in the tail gas is obviously reduced, and the influence, on the reaction, from the accumulated ash and accumulated water after filtration is avoided.

Description

technical field [0001] The invention relates to the field of automobile parts, in particular to an automobile exhaust cleaner device. Background technique [0002] Automobile exhaust is a very complex substance, which contains many harmful components, such as: unburned or incompletely burned CH compounds, NO x , CO, CO 2 , SO 2 、H 2 S. Lead and phosphorus pollution caused by trace amounts of aldehydes, phenols, peroxides, organic acids and lead and phosphorus gasoline. Among them, CO, NO x , SO 2 Air pollution is particularly serious and directly affects people's health. [0003] At present, the exhaust gas purification devices on the market generally adopt the method of adding catalysts, that is, adding catalysts to the fuel to make the gasoline burn fully, but this kind of catalyst still cannot avoid the incomplete combustion of gasoline, so a large amount of toxic exhaust emissions are inevitable. of. Contents of the invention [0004] The purpose of the present...
