Exhaust pipe capable of purifying tail gas

Abstract

The invention discloses an exhaust pipe capable of purifying tail gas. The exhaust pipe comprises an exhaust pipe main body, a metal shell and an oxygen sensor, wherein a purifying device is connectedto the middle of the exhaust pipe main body in an embedded manner, a tail gas inlet is connected to one end of the interior of the purifying device in an embedded manner, a filtering interlayer is fixedly connected to the middle part of the interior of the purifying device, a purifying screen is connected to one side of the filtering interlayer in an embedded manner, one side of the purifying screen is fixedly connected to an activated carbon adsorption layer, the other side in the purifying device is movably connected to purifying cotton, the purifying cotton further can adsorb automobile water vapor, the water vapor exhausted by the exhaust pipe is reduced, the purifying cotton has good moisture absorption, and the filtering screen can filter the tail gas preliminarily, so that the practicability of the exhaust pipe main body is improved effectively. Silencing pieces and silencing holes are used for reducing and dissipating sounds, then the reduced and reduced sounds are transmittedout from an outlet, a silencer can bear high speed continuous airflow impact, and the silencer improves the performance of practicality and good silencing effect of the exhaust pipe main body effectively.

Description

technical field [0001] The utility model relates to the technical field of exhaust pipes, in particular to an exhaust pipe capable of purifying exhaust gas. Background technique [0002] The exhaust pipe is also called the exhaust tailpipe, which is used to discharge the exhaust gas of the automobile. During the discharge process, the temperature of the exhaust gas is high and has a certain impact force. Therefore, in the design process of the exhaust pipe, the exhaust pipe Strength, especially the strength of the outlet end of the exhaust pipe is particularly important. [0003] But the existing exhaust pipe that can purify the exhaust gas will have the following disadvantages when it is used. The exhaust gas discharged from the car is very mixed, and it is very troublesome to purify, resulting in insufficient practicability of the exhaust pipe, and the impact of the exhaust gas on the environment. It is very large, which leads to the poor purification ability of the exist...
