Problems solved by technology

[0002] Catalyst refers to a catalytic device that converts harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The exhaust gas treatment efficiency and effect of existing catalytic converters are poor. And it cannot reflect the working status of the catalytic converter in real time
[0003] In addition, the catalysis of the existing exhaust gas catalytic converter is not very ideal

Abstract

The invention relates to the technical field of automobile exhaust treatment, in particular to a manufacturing process of a catalyst core of an automobile exhaust catalyst. The manufacturing process comprises the following steps that the material of a fixed plate is Q235 steel, and a mounting hole is formed through stamping machining; a first catalytic core and a second catalytic core are prepared according to the prior art, and a catalyzer coating is prepared and loaded according to the prior art; the first catalytic core and the second catalytic core are put in pretreatment liquid to be soaked for at least 15 min and then are taken out and directly dried; and the first catalytic core and the second catalytic core are mounted on the fixed plate, and the fixed plate is mounted in a shell. According to the catalyst core of the automobile exhaust catalyst and the manufacturing process of the catalyst core, structural design is reasonable and novel; and in the manufacturing process, the catalytic cores are pretreated, and therefore the catalytic efficiency of the catalytic cores can be obviously removed, and the catalytic effect of the automobile exhaust catalyst is better and higher.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to a manufacturing process of a catalytic converter core of an automobile exhaust catalytic converter. Background technique [0002] Catalyst refers to a catalytic device that converts harmful gases such as CO, HC and NOx emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. The exhaust gas treatment efficiency and effect of existing catalytic converters are poor. And it cannot reflect the working state of the catalytic converter in real time. [0003] In addition, the catalysis of the existing exhaust gas catalytic converter is not very ideal. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an automobile exhaust gas catalytic converter, which can improve the exhaust gas treatment efficiency and exhaust gas treatment effect of the catal...
