Treatment device for automobile exhaust gas abnormal emission

Abstract

The invention discloses a treatment device for automobile exhaust gas abnormal emission. The treatment device comprises a pipe groove arranged on a pipe body of an exhaust pipe; the part, close to anexhaust pipe opening, of the pipe body is provided with a middle rod; the annular pipe groove is formed in the part, corresponding to the middle rod, of the pipe body; two soft rods which are symmetrical to the middle rod are arranged in the pipe groove; a square groove is formed in the end, close to the middle rod, of each soft rod; a spring is fixedly connected in each square groove; a telescopic film is fixed at one end, far away from the middle rod, of each soft rod; and the telescopic films are fixed in the pipe groove. The treatment device has the advantages that when a three-way catalyst cannot timely finish waste gas treatment due to sudden change of the automobile load, a laser emitted into a heat collecting ball is smaller, so that the temperature of a sliding sleeve is reduced,the soft rods are straightened under the action of the elastic force of a spring and is close to the middle rod; the soft telescopic films, the middle rod and the soft rods are used for blocking the pipe body jointly; the waste gas in the pipe body can be directly discharged into an air bag, so that the waste gas can be stored.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment, in particular to a processing device for abnormal discharge of automobile tail gas. Background technique [0002] Because gasoline or diesel in the car will produce a large amount of harmful gases after burning, mainly including carbon monoxide, hydrocarbons, and nitrogen oxides; Carbon dioxide and water are released into the atmosphere. [0003] In order to comprehensively consider the working utilization rate and cost of the three-way catalytic converter, the three-way catalytic converter equipped with each vehicle in the prior art is suitable for the exhaust gas treatment under the normal working condition of the vehicle, but in actual use, the complexity of the working condition of the vehicle is far Much higher than normal working conditions, such as starting and climbing, will cause the fuel in the vehicle engine to not be completely combusted, causing a large amount ...

[0003] In order to comprehensively consider the working utilization rate and cost of the three-way catalytic converter, the three-way catalytic converter equipped with each vehicle in the prior art is suitable for the exhaust gas treatment under the normal working condition of the vehicle, but in actual use, the complexity of the working condition of the vehicle is far from Much higher than normal working conditions, such as starting and climbing, will cause the fuel in the vehicle engine to not be completely combusted, causing a large amount of waste to be contained in the exhaust gas, and the amount of these wastes often exceeds the normal processing range of the three-way catalytic converter, resulting in exhaust Exhaust gas is still more than expected, resulting in serious pollution
