A vehicle exhaust emission purification system

Abstract

The invention relates to an automobile exhaust emission and purification system. The automobile exhaust emission and purification system comprises a purification barrel, a flow detector, a controller, a driving module, a rotating motor, a harmful gas detector, a first electromagnetic valve and a second electromagnetic valve, wherein the purification barrel internally comprises a cover body, a first gas collection cavity, a honeycomb type filter screen layer, a second gas collection cavity, a solid purification agent layer, a third gas collection cavity, an emission channel and a circulating channel; the emission channel is communicated with the outside; the circulating channel is communicated with the interior of the purification barrel; the cover body is hinged at the bottom of the purification barrel; the rotating motor acts on the cover body; the rotating motor is connected with the controller through the driving module; the first electromagnetic valve is arranged at the inlet end of the emission channel; the second electromagnetic valve is arranged at the inlet end of the circulating channel; and the harmful gas detector is arranged in the third gas collection cavity and is used for detecting the purified gas and deciding the direction of the gas through the detection result. The automobile exhaust emission and purification system is good in reliability, high in practicability and good in purification effect, and can effectively purify the harmful gas in the automobile exhaust so as to prevent the harmful gas from being emitted to the outside air.

Description

technical field [0001] The invention relates to a purification system, in particular to an automobile tail gas emission purification system. Background technique [0002] The automobile tail gas in the prior art is directly discharged into the atmosphere through the exhaust pipe, and the main pollutants of the automobile tail gas include solid suspended particles, CO, HC, NOX, Pb and the like. Due to the increasing environmental pollution, it has had a huge impact on people's lives, and the popularity of family cars has become an important factor in environmental pollution and the chief culprit of smog. [0003] If the exhaust gas directly contacts the skin and eyes, it will block the hair follicles and sweat glands of the skin, cause dermatitis and conjunctivitis, and even cause corneal damage, which is very harmful to the human body; and a large part of the carbon dioxide that produces the "greenhouse effect" comes from Carbon dioxide in vehicle exhaust has a certain impa...
