Problems solved by technology

Automobile exhaust has been listed as one of the serious environmental pollution problems in the world. In the prior art, most of the treatment of automobile exhaust is only through activated carbon adsorption or adding Ca(OH) 2 , NaOH to treat carbon dioxide and solid particles in the exhaust gas; this kind of treatment method cannot completely and thoroughly treat the complex automobile exhaust gas, so the effect is not ideal, and often cannot meet the needs of higher and higher exhaust emission standards

Embodiment 1

[0033] The present embodiment provides an automobile exhaust gas purifying device with sound-absorbing effect, which includes an inlet pipe 1 , an outlet pipe 2 , a muffler 3 , a reducer 4 , a three-way catalytic converter 5 and an alkaline absorber 6 . The intake pipe 1 is connected to the muffler 3 to pass the automobile exhaust gas into the automobile exhaust purification device with noise reduction function, and the outlet pipe 2 is connected to the alkaline absorber 6 to discharge harmless exhaust gas.

[0034] The muffler 3 has a shell 31, and a sound-proof cover 32 is arranged inside the shell 31, and the sound-proof cover 32 is made of sound-absorbing material. The sound-absorbing material is selected from the sound-absorbing materials in the prior art such as: glass wool, slag wool, microporous bricks and the like. Two ends of the soundproof cover 32 are respectively provided with an air delivery pipe I 33 , and the air delivery pipe I 33 is directly connected to the ...

Embodiment 2

[0040] The present embodiment provides a foamed nickel material and a preparation method thereof. The foamed nickel material can be used as the sound-absorbing material of the automobile exhaust purification device provided by the present invention. Compared with traditional sound-absorbing materials, it has light weight , The advantage of strong sound absorption effect.

[0041] The raw materials of the nickel foam material include 100 parts of nickel, 1-10 parts of copper, 0.1-1 part of zinc, 0.1-1 part of titanium, 1-10 parts of aluminum powder, 20-30 parts of aluminum nitride, and 20-30 parts of rubber powder . The nickel foam material is prepared by the following method:

[0042] Heat the rubber powder to 300-400°C to melt, then add aluminum nitride powder to it, stir evenly and cool down; put nickel, copper, titanium, aluminum and other raw materials in a high-energy ball mill for 10-20 hours to obtain the particle size It is a powder of 1-5μm; extrude all raw material...

Abstract

The invention discloses an automobile exhaust gas purification device with a sound attenuation function and relates to the technical field of environmental protection. The automobile exhaust gas purification device with the sound attenuation function comprises an air inlet pipe, an air outlet pipe, a sound attenuation device, a reducer, a three-way catalyst and an alkaline absorber, wherein the sound attenuation device, the reducer, the three-way catalyst and the alkaline absorber are sequentially connected. The air inlet pipe is connected to the sound attenuation device. The air outlet pipe is connected to the alkaline absorber. According to the automobile exhaust gas purification device with the sound attenuation function, automobile exhaust gas is subjected to multi-stage treatment andthen discharged, and the discharge of harmful pollutants is low; and meanwhile the noise pollution brought by automobile exhaust gas is lowered through the sound attenuation device, and a quiet livingor working environment is given back to people.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an automobile tail gas purifying device with noise reduction function. Background technique [0002] In today's modern civilization, the automobile has become an indispensable means of transportation for human beings. It has brought great convenience to people's life and work, and has also developed into one of the pillars of modern material civilization. With the rapid development of the automobile industry and the continuous increase in the production and ownership of automobiles, more and more social problems have been caused: traffic congestion has become commonplace, noise pollution has seriously affected people's daily work and life, and the convenience, The advantages of comfort and efficiency are gradually offset by too many vehicles. The more serious problem caused thereby is the air pollution it brings, that is, automobile exhaust pollution. In large ...
