Automobile exhaust pipe with tail gas filtering function

Abstract

The invention discloses an automobile exhaust pipe with a tail gas filtering function. The automobile exhaust pipe comprises an exhaust pipe body and an air inlet pipe, wherein one side of the exhaustpipe body is communicated with the air inlet pipe; the other side of the exhaust pipe body is communicated with a filtering pipe through a flow guide pipe; the inner surface wall of the flow guide pipe is welded with a fixed circular disc positioned on the horizontal axial line of the flow guide pipe through flow guide plates in equal angle distribution; a rotating shaft is movably connected witha position at one side of the fixed circular disc and positioned inside the filtering pipe; a spiral blade is welded on the outer surface wall of the rotating shaft in the horizontal direction; a plurality of sound absorption convex blocks are uniformly distributed on the inner surface wall of the filtering pipe; a vacuum cavity is formed inside the casing of the filtering pipe. The automobile exhaust pipe has the advantages that the spiral blades can rotate under the tail gas circulation effect; the rotating shaft is driven to rotate; through the rotating effect of the spiral blade, the contact area between the active carbon adsorption plate and the tail gas can be effectively increased, so that the adsorption efficiency is improved; harmful gas in the tail gas can be efficiently adsorbed; the goals of filtering and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an exhaust pipe for automobiles with exhaust gas filtering function. Background technique [0002] The exhaust pipe is installed between the engine exhaust manifold and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, facilitating installation and prolonging the life of the exhaust muffler system. The exhaust pipe is mainly For light vehicles, miniature vehicles, passenger cars, motorcycles, the structure of the exhaust pipe is a double-layer corrugated pipe covered with a steel wire mesh sleeve, and the straight edge sections at both ends are covered with snap rings. In order to make the noise reduction effect better, the bellows inside It can be equipped with expansion joints or mesh sleeves. The main material of the exhaust pipe is stainless steel, and the material of the ferrule and the connecting pipe can be stain...

Problems solved by technology

[0003] However, the existing exhaust pipes for automobiles still have some shortcomings. On the one hand, they do not have the corresponding ability to filter exhaust gas. The exhaust gas is directly discharged into the air environment, which will directly lead to air pollution. On the other hand, the ability to reduce noise Insufficient, noise pollution is more serious
