Problems solved by technology

In the existing technology, some vehicles have applied chemical methods to treat the exhaust devices, but due to the high airflow intensity when the exhaust gas is discharged, the residence time of the gas in the chemical reagent is short, and there is not enough reaction time, which makes the treatment result unsatisfactory. Strong air flow, easy to spray chemical reagents

Abstract

The invention provides a motor vehicle exhaust purification device, which includes an automobile exhaust pipe, and is characterized in that: it also includes a U-shaped pipe, the U-shaped pipe includes an air intake pipe, a bent pipe and an air outlet pipe, and the air intake pipe is connected with the automobile exhaust pipe. The air intake pipe is provided with a baffle, the baffle makes the inside of the U-shaped pipe circuitously connected, the port of the air outlet pipe is opened, and the U-shaped pipe is equipped with automobile exhaust gas treatment fluid. The invention has the beneficial effects of reducing the intensity of the automobile exhaust airflow, increasing the residence time of the automobile exhaust in the automobile exhaust treatment liquid, and reducing the probability that the automobile exhaust treatment liquid is washed out by the air flow; greatly reducing the harmful and toxic gases in the automobile exhaust content, reducing the content of solid particles contained in automobile exhaust, thereby reducing the pollutants discharged into the air by automobile exhaust; it has simple structure, low manufacturing cost, small space occupation and does not affect automobile power, convenient maintenance, and low processing cost , High processing efficiency and so on.

Description

technical field [0001] The invention belongs to the technical field of automobile environmental protection, and in particular relates to a motor vehicle tail gas purification device. Background technique [0002] With the continuous improvement of living standards, automobiles have gradually become a common means of transportation in people's daily life, and the impact of pollutants emitted by automobiles on the environment has become increasingly serious. On June 14, 2013, the State Council deployed ten measures for the prevention and control of air pollution, stipulating that local governments can restrict the use of motor vehicles according to the pollution level. It can be seen that the impact of automobile and other motor vehicle exhaust on the environment has attracted more and more attention. In the existing technology, some vehicles have applied chemical methods to treat the exhaust devices, but due to the high airflow intensity when the exhaust gas is discharged, th...
