Abstract

The invention provides an integrated type three-way catalyst preparation device which solves the problem that gamma-Al2O3 on a second carrier is gathered and dispersed unevenly in the prior art. The integrated type three-way catalyst preparation device comprises one or more raw material placing containers, a raw material mixing device which communicates with discharge holes of the raw material placing containers, a loading device which communicates with a discharge hole of the raw material mixing device, a transmitting device which is used for conveying the second carrier to the position of the loading device to load, and a drying and burning device which is used for drying and burning the loaded second carrier; each raw material placing container comprises an assistant tank, an oxygen storage material tank, a noble metal tank and a first carrier tank; the raw material mixing device comprises a primary mixing tank and a final stirring tank; a discharge hole of the assistant tank, a discharge hole of an oxygen storage material tank and a discharge hole of the noble metal tank communicate with a charge hole of the primary mixing tank; a discharge hole of the primary mixing tank and adischarge hole of the first carrier tank communicate with a charge hole of the final stirring tank; a discharge hole of the final stirring tank communicates with the loading device.

Description

technical field [0001] The invention relates to the field of three-way catalysts, in particular to an integrated three-way catalyst preparation device. Background technique [0002] In order to eliminate the harm of the above-mentioned pollutants to the environment and the human body, the most effective treatment method is to install a catalytic converter in the engine exhaust system to catalytically convert the exhaust gas of the vehicle before it is discharged. The basic principle is that through the action of the catalyst, Oxidize and reduce CO, HC and NOX respectively to carbon dioxide (CO2), nitrogen (N2) and water vapor (H2O) which are harmless to human health. Harmful substances act as a catalyst for purification, and this catalyst is called a three-way catalyst (TWC). [0003] Three-way catalysts usually use noble metals Pt, Rh, and Pd as active components, cordierite as the first carrier, and γ-Al2O3 as the second carrier (active coating). On bluestone, and add Ce...
