Automobile three-way catalyst convenient to detach

Abstract

The invention relates to the field of automobile tail gas treatment, in particular to an automobile three-way catalyst convenient to detach. The automobile three-way catalyst convenient to detach comprises a catalyst shell, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are connected with the two ends of the catalyst shell respectively. The automobile three-way catalyst convenient to detach is characterized by further comprising an air inlet pipe edge thickening layer located at the edge of the air inlet pipe and is separately attached to the outer edge of the catalyst shell, and when the air inlet pipe edge thickening layer is separated from the outer edge of the catalyst shell, the air inlet pipe and the catalyst shell are separated, and a cleaning agent carrier in the catalyst shell is exposed. According to the automobile three-way catalyst convenient to detach, a filtering piece is used for filtering tail gas to some extent to prevent internal particles and the like from blocking holes of the cleaning agent carrier. The structure that the air inlet pipe and the catalyst shell are separated is adopted, and the catalyst shell is opened so that the cleaning agent carrier, the filtering piece and other structures can be detached. An air outlet pipe front end flow guide piece of an arch structure is adopted, air is guided to mainly flow in the middle, and tail gas settlings are prevented from accumulating at the front end of the catalyst shell.

Description

technical field [0001] The invention relates to the field of automobile exhaust gas treatment, in particular to an automobile three-way catalytic converter which is convenient to disassemble. Background technique [0002] The three-way catalytic converter for automobiles is the most important external purification device installed in the exhaust system of automobiles. It can convert harmful gases such as carbon monoxide, nitrogen oxides, and hydrocarbons from automobile exhaust into harmless carbon dioxide, carbon dioxide, and carbon dioxide through oxidation and reduction. water and nitrogen. Because this kind of catalytic converter can convert the three main harmful substances of exhaust gas red into harmless substances at the same time, it is called a three-way catalytic converter. [0003] At present, the holes in the three-way catalytic converter are easy to be blocked, and after the blockage, the catalytic converter shell needs to be destroyed and replaced, which is t...

AI Technical Summary

Problems solved by technology

[0003] At present, the holes in the three-way catalytic converter are easy to clog, and after clogging, the catalytic converter shell needs to be destroyed and replaced, which is troublesome; moreover, the three-way catalytic converter has poor fireproof performance, and does not have a pre-filtering structure. The front end is easy to accumulate exhaust deposits
