Problems solved by technology

The outermost part of the catalytic converter is a stainless steel shell, and its interior is a catalyst carrier; due to the diffusion from the center to the surroundings, the gas flow in the center is the fastest, and the utilization rate of the catalyst is higher. At the same time, the utilization rate of the catalyst is less, and the rational utilization of the catalyst cannot be achieved, the cost is high, and at the same time, it causes a waste of resources.

Abstract

A catalyst carrier for automobile exhaust gas purification. The carrier includes a sleeve body, a grid installed inside the sleeve body, and a porous composite ball fixedly arranged in the grid. There is an exhaust gas channel between the porous composite ball and the grid wall, and the core ball can ensure The carrier is stable during the working process, and the porous composite layer makes the carrier more effective in carrying the catalyst and improving the evolution effect of exhaust gas.

Description

technical field [0001] The invention relates to a catalyst carrier for automobile tail gas purification and belongs to the technical field of automobile tail gas purification. Background technique [0002] The automotive catalytic converter is an engine external purification device that can purify carbon monoxide (CO), hydrocarbons (HC), hydrocarbons (HC) and nitrogen oxides (NO) emitted from the automotive engine. A catalytic converter that can only purify CO and HC is an oxidation catalytic converter; a catalytic converter that can purify CO, HC and NO that pollutes the environment is a three-way catalytic converter. The outermost part of the catalytic converter is a stainless steel shell, and its interior is a catalyst carrier; due to the diffusion from the center to the surroundings, the gas flow in the center is the fastest, and the utilization rate of the catalyst is higher. At the same time, the utilization rate of the catalyst is lower, so the rational utilization o...
