Tail gas treating device for automobile exhaust pipe

Abstract

The invention discloses a tail gas treating device for an automobile exhaust pipe, and relates to the technical field of automobile accessories. The tail gas treating device comprises a body, a gas inlet pipe arranged on one side of the body and a gas outlet pipe arranged on the other side of the body, wherein a Venturi pipe is connected between the exhaust pipe and the gas inlet pipe, the Venturipipe comprises a cylindrical throat part, a hollow spherical joint is clamped to the cylindrical throat part in a matched mode, a buffering device is arranged on the body, the buffering device comprises a lantern ring, a plurality of counter bores are formed in the inner wall of the lantern ring, balls are clamped in the counter bores in a matched mode, the balls are connected with the outside ofthe body in an abutting mode, first springs are arranged in the counter bores along the radial outer side of the lantern ring, and the first springs are connected with the balls in an abutting mode.The tail gas treating device can be well stabilized on the exhaust pipe, the damage to the automobile exhaust pipe can be reduced, and the good vibration reduction protection effect on the device bodyis achieved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an exhaust gas treatment device for an automobile exhaust pipe. Background technique [0002] After the combustion of automobile gasoline, a large amount of harmful gases are produced, mainly including carbon monoxide, hydrocarbons, and nitrogen oxides. Generally, a three-way catalytic converter is installed in the middle of the exhaust pipe to process the above-mentioned mixed harmful gases to generate carbon dioxide. and water before being released into the atmosphere. Nevertheless, after the original exhaust gas passes through the three-way catalytic converter, it still contains more particulate impurities, heat and unremoved harmful gases. Therefore, in order to reduce the harm caused by automobile exhaust to the environment, it is used to further purify automobile exhaust. Processing devices have emerged as the times require, and this kind of auto parts is developing mor...

AI Technical Summary

Problems solved by technology

However, the existing exhaust gas treatment device has a large volume and weight, and the load on the exhaust pipe of the automobile is relatively high. figure 1 as shown, figure 1 It is a schematic diagram of the connection between the exhaust gas treatment device and the exhaust pipe of the car in the prior art. When the car is running at high speed or / and bumps, the swaying and vibration of the car body will cause damage to A and the body of the exhaust gas treatment device, thereby affecting the vehicle. The service life of the exhaust pipe and the exhaust gas treatment device, therefore, considering the cost of accessories, the exhaust gas treatment device needs to be improved
