Motor vehicle exhaust gas purification catalysis device integral-type precious metal dosage control unit

Abstract

The present invention discloses a motor vehicle exhaust gas purification catalysis device integral-type precious metal dosage control unit, and aims to provide an integral-type precious metal dosage control unit which can achieve high-dispersion addition of an active ingredient precious metal and sufficient and uniform mixing of the active ingredient precious metal with slurry for full adsorption of the precious metal to improve the stability of the slurry so as to improve the catalytic performance. The motor vehicle exhaust gas purification catalysis device integral-type precious metal dosage control unit includes a precious metal high-dispersion dropping device and a dosing device, the precious metal high-dispersion dropping device comprises a first support frame, a horizontally-distributed arc-shaped flow guide tube arranged on the top of the first support frame, and a liquid storage pot which is arranged on the first support frame and located above the arc-shaped flow guide tube, the bottom of the liquid storage pot is provided with a liquid outlet pipe communicating with the arc-shaped flow guide tube, the arc-shaped flow guide tube is provided with a plurality of vertical liquid dropping tubes, and the vertical liquid dropping tubes are provided with switching valves.

Description

Technical field [0001] The invention relates to a batching device for a motor vehicle exhaust purification catalyst, in particular to an integral precious metal batching device for a motor vehicle exhaust purification catalyst. Background technique [0002] The emergence and development of automobiles have significantly improved people’s lives. While improving the quality and efficiency of people’s lives, they have also promoted the development of economy and productivity. However, with the rapid growth of vehicle ownership, the amount of vehicle exhaust pollutants has increased sharply. The environmental pollution caused by it is becoming more and more serious. If it is not strictly controlled, it will cause catastrophic harm to humans and the natural environment. [0003] At present, the installation of catalytic purification devices for exhaust gas has become an effective way to prevent and control automobile exhaust pollution; for this reason, catalytic workers have made long-t...
