Problems solved by technology

It is difficult to get a good detection of the exhaust gas emitted by the existing automobiles, and the data of the automobile exhaust emission needs to be tested by a separate instrument; in addition, some automobiles are equipped with an exhaust gas treatment device, which catalyzes the exhaust gas by placing a catalyst, such as three Element catalytic converter, which mainly converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides in automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction
However, the activity of the catalyst is likely to decrease under high temperature conditions, and the deposition of particulate carbon on its surface will reduce the surface activity of the catalyst or even invalidate it. Therefore, most exhaust gas purifiers will add a filter device before the catalyst carrier
For the filtering effect of the filter device, it is difficult to carry out good inspection and testing on the existing automobile exhaust monitoring device

Embodiment 1

[0030] Please refer to figure 1 and figure 2, the present embodiment provides a vehicle exhaust monitoring device, which includes an exhaust gas inlet 110, a monitoring box 120, and a purification box 150 connected in sequence. The tail gas inlet 110, the monitoring box 120 and the data related to the tail gas are detected in the monitoring box 120, such as temperature, humidity, PM2.5 and other data. After the tail gas is detected, it is purified by the purification box 150. The purification box 150 includes Rectangular clean box shell 151, the clean box shell 151 is provided with an exhaust gas treatment inlet 157 communicating with the monitoring box 120, and the middle part of the inner cavity of the clean box shell 151 is provided with a fine filter catalytic frame 155 detachably connected with the clean box shell 151, the The fine filter catalytic frame 155 can filter the fine particles in the exhaust gas passing through the fine filter catalytic frame 155, and also pu...

Embodiment approach

[0032] As a preferred embodiment, the corridor frame includes one or more sets of frames. When there is only one set of frames, it includes the first frame 152, and the first frame 152 divides the deceleration and cooling zone into the first outer The corridor and the first inner corridor, one end of the first outer corridor communicates with the exhaust gas treatment inlet 157, and the other end of the first outer corridor communicates with the first inner corridor through the gap between the first frame 152 and the purification box shell 151 , the two sides of the fine filter catalytic frame 155 are respectively the first inner corridor and the release area 170 . After such setting, the exhaust gas first passes through the first outer corridor in the purification box shell 151, and then turns back and enters the first inner corridor, which prolongs the flow path of the exhaust gas in the purification box shell 151 and facilitates the process of exhaust gas purification. Larg...

Abstract

The invention provides an automobile exhaust gas monitoring device, which relates to the technical field of automobile exhaust gas monitoring. The exhaust gas treatment inlet connected with the monitoring box, the middle part of the inner cavity of the purification box shell is provided with a fine filter catalytic frame that is detachably connected with the clean box shell, and the fine filter catalytic frame divides the inner cavity of the clean box shell into a deceleration and cooling area and a release area. The deceleration and cooling zone is connected with the exhaust gas treatment outlet of the purification box. The deceleration and cooling zone is provided with a corridor frame for guiding the flow direction of the exhaust gas. The exhaust gas in the deceleration and cooling zone flows from the exhaust gas treatment inlet to the position of the fine filter catalytic frame. The invention has the advantages of adjustable exhaust gas filtration and purification degree and better filtration and purification effect.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust monitoring, in particular to an automobile exhaust monitoring device. Background technique [0002] Automobile exhaust components mainly include hydrocarbons, nitrogen oxides, carbon monoxide, and particulate carbon. It is difficult to get a good detection of the exhaust gas emitted by the existing automobiles, and the data of the automobile exhaust emission needs to be tested by a separate instrument; in addition, some automobiles are equipped with an exhaust gas treatment device, which catalyzes the exhaust gas by placing a catalyst, such as three Element catalytic converter, which mainly converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides in automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. However, the activity of the catalyst is likely to decrease under high temperature conditions, and the deposition...
