The invention discloses a high-dispersion adding device for noble metal components of a motor vehicle exhaust gas purification catalyst, which includes a platform, and the platform is provided with two pairs of legs for supporting the platform, and the legs include two The foot bar, the said platen is provided with a number of funnel positioning holes penetrating through the surface of the platen, the said funnel positioning hole is provided with a separating funnel, the separating funnel is provided with a liquid separating valve, and the said platen The lower part is provided with a dispersing and uniform material cylinder, and the dispersing and uniform material cylinder comprises a cylinder body, a barrel bottom, and a top cover. There is a discharge pipe at the bottom, and a discharge valve is provided on the discharge pipe. The beneficial effect of the present invention is that the structure is reasonable, the fusion of the coating slurry of the exhaust gas purification catalyst and the precious metal components can be quickly and effectively realized, the dispersion effect of the precious metals in the slurry is good, and the distribution of components such as precious metals in the obtained slurry can be ensured Uniform and stable.
Description
technical field [0001] The invention belongs to the technical field of adding noble metals to coating slurry of exhaust gas purification catalytic converters, and in particular relates to a device for adding highly dispersed noble metal components to exhaust gas purification catalytic converters of motor vehicles. Background technique [0002] With the increasing pollution of automobile exhaust, in order to suppress the generation of harmful substances in exhaust, governments of various countries have put forward strict controls on the emission of automobile exhaust. Among them, the European standard is currently the main vehicle emission standard that our country uses for reference. The pollutant emission limits in my country's motor vehicle pollutant emission standards are roughly equivalent to the European emission standards, so similar names are still used in China, but there are still certain technical differences between the two. The "Light Vehicle Pollutant Emission ...
