Device for fully treating automobile exhaust

Abstract

The invention discloses a device for fully treating automobile exhaust. The device comprises a three-way pipe, wherein a center cavity, an input pipe, a high-temperature pipe and a heating pipe are arranged in the three-way pipe; the center cavity communicates with the input pipe, the high-temperature pipe and the heating pipe; the end, away from the center cavity, of the high-temperature pipe is connected with a first three-way catalytic converter; a heating sheet is mounted in the heating pipe; the end, away from the center cavity, of the heating pipe is connected with a second three-way catalytic converter; an adjusting mechanism is arranged in the center cavity; and the adjusting mechanism comprises a rocker arm and a blocking plate. The device for fully treating the automobile exhaust is simple in structure, and is capable of separately treating unqualified exhaust gases by virtue of the temperature difference of the exhaust gases, thereby achieving a full treatment effect on the automobile exhaust, protecting the three-way catalytic converters, prolonging the service lives of the three-way catalytic converters, ensuring that the exhaust gases are effectively purified and treated, and practically achieving an environmental protection effect.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to a device for fully treating automobile exhaust gas. Background technique [0002] When the car is in use, it will produce exhaust gas. The exhaust gas contains hundreds of different compounds. The pollutants include solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. It must be treated before being released into the air. The treated exhaust gas can effectively reduce the harmful components in it. The use of the purifier in the three-way catalytic converter can effectively oxidize HC compounds into water (H2O) and Carbon dioxide, NOx is reduced to nitrogen and oxygen, and CO is oxidized at high temperature to colorless, non-toxic carbon dioxide gas. [0003] However, the three-way catalytic converter must work in a suitable temperature environment. The three-way catalytic converter in a normal...

Problems solved by technology

[0003] However, the three-way catalytic converter must work in a suitable temperature environment. The three-way catalytic converter in a normal temperature environment has no effect on exhaust gas. When the car is started or the ignition is not normal, the engine temperature is not enough, etc., and the exhaust gas is not fully combusted. And the temperature is too low, the unburned low-temperature gas enters the three-way catalytic converter, and the insufficiently combusted gas will burn again in the three-way catalytic converter, and then the problem of high temperature of the three-way catalytic converter will occur. Damage to the three-way catalytic converter, too low or too high temperature can not achieve the reaction catalytic effect on the gas, so that the efficiency of tail gas treatment is greatly reduced, and a large amount of harmful gas will be discharged into the air
