Problems solved by technology

However, even if the tail gas is completely converted into carbon dioxide, it will have a great impact on the environment. According to scientific statistics, with the rapid increase in the number of cars, the greenhouse effect is becoming more and more serious. For example, in my country, due to the greenhouse effect, in recent years, The four seasons are not very obvious, therefore, the treatment of carbon dioxide in vehicle exhaust is still very necessary
[0004] However, for the treatment of carbon dioxide, since there is no catalyst, it needs to be carried out with consumable substances, so it cannot be loaded together with the above catalysts, and if the carbon dioxide is still absorbed by pores or honeycomb structures, it will be largely Increase the exhaust resistance and cause the problem of poor exhaust of the car. Therefore, the treatment of carbon dioxide is a difficult technical problem

Embodiment 1

[0020] figure 1 , figure 2 Shown is the first embodiment of the automobile exhaust processor, wherein the automobile exhaust processor includes an exhaust chamber 120 surrounded by the outer shell 1 and the inner shell 2; the liquid storage chamber is between the outer shell 1 and the inner shell 2 121, and a support plate 4 is also provided between the outer shell 1 and the inner shell 2. The setting of the support plate 4 needs to ensure that the interior of the liquid storage chamber 121 is connected everywhere; A filter frame 3 made of a thin-walled metal tube, and the thin-walled metal tube of the filter frame 3 communicates with the liquid storage chamber 121; the surface of the thin-walled metal tube is provided with continuous slits along the longitudinal direction of the metal tube; The carbon dioxide treatment liquid is stored in the liquid storage chamber 121; the casing 1 is provided with a liquid injection port 1210 leading to the liquid storage chamber; the two...

Embodiment 2

[0024] Figure 4 Shown is the cross-sectional schematic diagram of the second embodiment of the automobile exhaust processor, which is different from the first embodiment in that: the inner side of the filter frame 3 also includes criss-crossing, which is also composed of the thin-walled metal tubes. The pipe 30, the supplementary pipe 30 communicates with the thin-walled metal pipe forming the outline of the filter frame 3, so as to increase the evaporation area of ​​the carbon dioxide treatment liquid.

[0025] In addition, as a preferred mode of the automobile exhaust processor, the carbon dioxide treatment solution can be calcium hydroxide solution or sodium hydroxide solution, which is cheap and easy to replenish.

[0026] In this automobile exhaust processor, due to the thermal expansion and contraction effect of the thin-walled metal pipe forming the filter frame 3, when the automobile is not working, the exhaust pipe is in a low temperature state, and the slits of the ...

Abstract

The invention provides an automobile exhaust treater and belongs to the field of automobile components. The automobile exhaust treater comprises an exhaust cavity encircled with an outer casing and an inner casing, a liquid storage cavity is positioned between the outer casing and the inner casing, a filtering frame formed by thin-wall metal pipes communicated everywhere is arranged in the exhaust cavity, the thin-wall metal pipes of the filtering frame are communicated with the liquid storage cavity, continuous fine slits are arranged on the surface of the thin-wall metal pipes in the longitudinal direction of the metal pipes, carbon dioxide treating fluid is stored in the liquid storage cavity, the outer casing is provided with a liquid injection port leading to the liquid storage cavity, and two ends of the exhaust cavity are provided with an air inlet and an exhaust port respectively. The treater can effectively degrade carbon dioxide on the premise that no exhaust resistance is caused to automobile exhaust.

Description

Technical field [0001] The invention relates to the field of automobile components, in particular to an automobile exhaust processor connected to an automobile exhaust pipe. Background technique [0002] With the acceleration of the pace of urban life, the number of cars is increasing day by day, and the problem of car exhaust has become more and more serious in recent years, and the urban air quality has been greatly affected. Therefore, the treatment of car exhaust is a very important issue at present. [0003] The main substances produced by the engine after gasoline combustion are carbon dioxide, carbon monoxide, nitrogen oxides, sulfides, etc. Among them, the content of carbon monoxide and nitrogen oxides is relatively large, and they are more harmful to the environment. Therefore, install There are filters, in which catalysts are added, which are mainly used to convert carbon monoxide into carbon dioxide and nitrogen oxides into nitrogen. However, even if the tail gas...
