Automobile Exhaust Processor

Abstract

The invention provides an automobile exhaust treater. The automobile exhaust treater comprises a barrel-shaped absorbing barrel, wherein a gas inlet is formed in the center of the barrel bottom of the absorbing barrel; the automobile exhaust treater further comprises a barrel cover matched with the barrel opening of the absorbing barrel; a spiral wall which radiates from the inside to the outside with the circular center of the barrel cover as a radial center is arranged on the barrel cover; a gas outlet is formed in the barrel cover; the gas outlet is positioned at the end of the outmost ring of the spiral wall; after the barrel cover is mounted the absorbing barrel, the two ends of the spiral wall press against the barrel bottom of the absorbing barrel and a cover plane of the barrel cover respectively, so that a gas flow entering the absorbing barrel from the gas inlet can only go to the outmost ring from the inner ring of the spiral wall one by one and then be emitted from the gas outlet; the spiral wall consists of a spiral substrate and carbon dioxide absorbing layers arranged on the front and back surfaces of the spiral substrate. The automobile exhaust treater can obtain a relatively high carbon dioxide absorbing efficiency on the basis that resistance to exhaust emission is basically not formed.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto exhaust processor. Background technique [0002] After the combustion of automobile gasoline, a large amount of harmful gases are produced, mainly including carbon monoxide, hydrocarbons, and nitrogen oxides; for this reason, it is generally necessary to use a three-way catalytic converter to treat this mixed harmful gas to generate carbon dioxide and water. re-emitted into the atmosphere. Nevertheless, the emission of a large amount of carbon dioxide still makes the greenhouse effect more and more serious and makes the ecological environment worse. [0003] In view of this situation, the current tail gas carbon dioxide treatment equipment mainly includes two structures, one of which is to make carbon dioxide gas directly pass through the porous carbon dioxide absorber, such as metal oxides (calcium oxide, sodium oxide), this structure It can absorb carbon dioxide well, but at...

Problems solved by technology

[0003] In view of this situation, the current tail gas carbon dioxide treatment equipment mainly includes two structures, one of which is to make carbon dioxide gas directly pass through the porous carbon dioxide absorber, such as metal oxides (calcium oxide, sodium oxide), this structure It can absorb carbon dioxide well, but at the same time it will cause serious resistance to the exhaust gas, which will affect the performance of the engine; the other is a hollow cavity structure, and the inner wall of the cavity and the partition in the cavity are covered with a carbon dioxide absorbing layer; The structure basically has no resistance to the emission of exhaust gas, but when the exhaust gas flows inside the hollow cavity, the flow velocity is basically parallel to the carbon dioxide absorption layer, and carbon dioxide cannot automatically close to the absorption layer, so the absorption efficiency of this structure for carbon dioxide is very limited

On the other hand, the current carbon dioxide absorbing devices all need to be assembled and unloaded as a whole, and the carbon dioxide absorbing materials are consumables, resulting in high cost of use
