Tail gas purification catalyst coating device

Abstract

The invention provides a tail gas purification catalyst coating device and a method. The tail gas purification catalyst coating device is characterized by comprising a slurry filtering equipment, anda first connecting port, a filter element and a second connecting port are arranged on the slurry filtering equipment in sequence along the flowing direction of the slurry, wherein the filter elementand the second connecting port are arranged inside a cylinder body; and the first connecting port is connected with a stirring device in a communicating mode, and a diaphragm pump for pumping the slurry to the slurry filtering equipment is further connected between the stirring system and the slurry filtering equipment. The tail gas purification catalyst coating device comprises the slurry filtering equipment, the slurry entering the coating system is free of particles and impurities, so that the uniformity of the slurry is improved, and the phenomenon of hole blockage is avoided; and the tailgas purification catalyst coating method adopts a secondary coating method, the loading capacity of the coating wet weight is controllable, the coating thickening consistency is good, and then the production efficiency is further improved, and the consistency of products is ensured.

Description

technical field [0001] The invention relates to the field of tail gas purification, in particular to a catalyst coating device for tail gas purification. Background technique [0002] The Ministry of Ecology and Environment recently released the "China Motor Vehicle Environmental Management Annual Report 2018", which shows that my country has become the world's largest motor vehicle production and sales country for nine consecutive years, and motor vehicle pollution has become an important source of air pollution in my country and an important cause of environmental air pollution. , the urgency of motor vehicle pollution prevention and control has become increasingly prominent. Motor vehicle exhaust emission control is mainly organic internal and external control. In-machine control is mainly to control the combustion process of fuel through the transformation of the engine, so as to reduce the generation of pollutants. In-machine purification mainly includes the following ...

AI Technical Summary

Problems solved by technology

However, in the actual coating process, the slurry is easy to stick to the wall during the mixing and pipeline transportation process, the edge of the mixing tank, the diaphragm pump and the delivery pipe, etc., and then the slurry on the wall dries and falls off into the slurry, resulting in Slurry particles, resulting in slurry particles in the suction pan of the coating equipment

After the carrier is coated, the problems of particle clogging and uncontrollable wet weight of the coating are prone to occur, resulting in a decrease in production efficiency and unguaranteed product consistency
