Automobile exhaust gas purifier

Abstract

The invention relates to an automobile exhaust gas purifier. The automobile exhaust gas purifier includes a filtering box (1); the filtering box (1) includes a master pipe (2) positioned on the upper part and two branched slave pipes (5) positioned on the lower part; each slave pipe (5) is successively provided with an exhaust fine tube (4) and a ceramic cellular carrier (3) in the gas flow direction; a hush pipe (7) is arranged in the filtering box (1); and branch pipes (8) are arranged on the hush pipe (7), wherein holes are formed in walls of the branch pipes. According to the automobile exhaust gas purifier, tail gas is transformed into CO2, H2O, N2, and O2 through two-stage filtering of the exhaust fine tube and the ceramic cellular carrier; micro holes formed in partition walls can effectively filter carbon smoke particles in exhaust gas, the carbon smoke particles will be burned under the action of a catalyst coating, and the ceramic cellular carrier possess a regeneration function; the exhaust gas is distributed to the slave pipes from the master pipe, and then the filtering area is increased in a limited space; and the automobile exhaust gas purifier has a good silencing effect.

Description

technical field [0001] The invention relates to an automobile tail gas purifier, which is used for purifying the automobile tail gas. It belongs to the technical field of automobile equipment. Background technique [0002] At present, ordinary automobile exhaust purifiers use catalysts to interact with NO, NO in automobile exhaust. 2 react with CO to produce 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 soot particles, the existing automobile exhaust purifiers cannot effectively filter the soot particles, which will cause environmental pollution; while the existing purification Due to the inability to ensure a good filter area in a limited space, the exhaust gas purification is not complete, and the environment will be polluted after being discharged; the existing exhaust gas silencing is realized by setting the silencing sheet, but the silencing sheet is easy to loosen an...

Problems solved by technology

[0002] At present, ordinary automobile exhaust purifiers use catalysts to interact with NO, 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 soot particles, the existing automobile exhaust purifiers cannot effectively filter the soot particles, which will cause environmental pollution; while the existing purification Due to the inability to ensure a good filter area in a limited space, the exhaust gas purification is not complete, and the environment will be polluted after being discharged; the existing exhaust gas silencing is realized by setting the silencing sheet, but the silencing sheet is easy to loosen and fall off, and it is not easy to to better noise reduction
