Catalyst adding device for reducing automobile pollutant emission

Abstract

The invention discloses a catalyst adding device for reducing automobile pollutant emission, and relates to the technical field of automobiles. The catalyst adding device for reducing automobile pollutant emission comprises a tail gas pipe, a transmission shaft is slidably connected to the left end of the tail gas pipe, an inner filter screen is fixedly connected to the right end of the transmission shaft, the surface of the inner filter screen is slidably connected into the tail gas pipe, a blocking filter screen is fixedly connected into the tail gas pipe, and the blocking filter screen is located on the right side of the inner filter screen. According to the catalyst adding device for reducing the automobile pollutant emission, through the barrel-shaped connecting pipe, it is guaranteed that when passing through the barrel-shaped connecting pipe, a catalyst does not make contact with and react with catalyzed tail gas in the outer filter screen again, waste of the catalyst caused by the fact that the catalyst makes contact with and reacts with the catalyzed tail gas again in the using process is avoided, the high efficiency of catalyst application is improved, and the tail gas pipe can be conveniently disassembled to regularly clean the internal structure of the tail gas pipe.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a catalyst adding device for reducing pollutant emissions from automobiles. Background technique [0002] With the continuous increase of my country's per capita income, the purchase of cars is increasing. At present, more and more families own private cars. During the use of cars, a large amount of exhaust gas will be emitted. With people's awareness of environmental protection People gradually realize that the emission of automobile exhaust will seriously affect the atmospheric environment and cause the deterioration of the ecological environment. Therefore, in recent years, the emission of automobile exhaust has been continuously rectified. With the treatment of automobile exhaust, the addition and use of catalysts will It is particularly important, especially when using a catalyst to neutralize the pollutants produced by automobile exhaust. Most of the existing catalyst add...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to at least solve one of the technical problems in the prior art, and provide a catalyst adding device for reducing automobile pollutant emissions, which can solve the problem of avoiding the re-contact reaction of the catalyst with the catalyzed tail gas when it is in use. Causes waste of catalyst, improves the efficiency of catalyst application, and facilitates disassembly and regular cleaning of the internal structure of the exhaust pipe
