Automobile silencing device with high tail gas purification performance

Abstract

The invention discloses an automobile silencing device with high tail gas purification performance. The automobile silencing device comprises a silencing device body, wherein a shell is arranged on the outer side of the silencing device body, an inner container is arranged on the inner side of the shell, a plurality of connecting plates are arranged between the inner container and the shell in a welded mode, a first silencing groove is formed in one end of the inner container, a second silencing groove is formed in one side of the first silencing groove, a third silencing groove is formed in one side of the second silencing groove, and a fourth silencing groove is formed in one side of the third silencing groove. The automobile silencing device is arranged on an automobile exhaust pipe, noise can be effectively reduced, urban noise pollution can be reduced, automobile tail gas can further be effectively treated and then emitted, air pollution in cities can be reduced, gas in the exhaust pipe can be filtered and then emitted, filtered-out impurities can be collected, the performance of the automobile silencing device is stabler than that of an automobile silencer in the market, the noise is smaller, harmful substances in the tail gas are less, the service life is long, the performance is stabler, the noise reduction and decontamination performance is better, and the environment is protected.

Description

[0001] Technical field: [0002] The invention relates to the field of automobile noise reduction, in particular to an automobile noise reduction device with high tail gas purification performance. [0003] Background technique: [0004] The automobile muffler is mainly used to reduce the noise generated by the engine of the motor vehicle. The principle is that the automobile exhaust pipe is composed of two pipes with different lengths. The length difference is equal to half of the wavelength of the sound waves emitted by the car, so that the two rows of sound waves interfere with each other and cancel each other out when they are superimposed, reducing the sound intensity and reducing the transmitted sound, thereby achieving the effect of noise reduction. [0005] Car noise reduction is widely used in the automotive field. With the advancement of science and technology and the improvement of people's living standards, the noise and harmful gases emitted by cars are very troubl...

AI Technical Summary

Problems solved by technology

[0005] Car noise reduction is widely used in the automotive field. With the advancement of science and technology and the improvement of people's living standards, the noise and harmful gases emitted by cars are very troublesome. Although the silencers on the market have the effect of noise reduction, the effect is poor. , can not effectively achieve the effect of noise reduction, nor can it effectively remove harmful gases in automobile exhaust, pollute the environment, and seriously affect people's living environment and air quality
