Automobile exhaust detecting and treating system

Abstract

The invention discloses an automobile exhaust detecting and treating system. The automobile exhaust detecting and treating system comprises an automobile exhaust detector, wherein the automobile exhaust detector is arranged at a gas inlet; the gas inlet is connected with an exhaust treating device; a flushing device and a gas return pipe are respectively arranged on two sides of the exhaust treating device; a gas outlet is formed in the other side of the exhaust treating device; filter screens are respectively arranged on the gas inlet and the gas outlet; each filter screen is filled with activated carbon; the filter screens are arranged on the inner side of the flushing device; by the exhaust treating device, HC, CO and nitrogen oxide in exhaust are converted into non-toxic gas and then discharged; by the filter screens and the activated carbon, solid micro-particles in the exhaust can be adsorbed; and by the gas return pipe and the automobile exhaust detector on an opening of the gas return pipe, the automobile exhaust can be discharged if the automobile exhaust is qualified, and if the automobile exhaust is not qualified, the automobile exhaust continues being treated by the exhaust treating device; and finally, by the flushing device, impurities in the activated carbon can be flushed away, and soot particles adhered to the exhaust treating device can also be flushed away.

Description

technical field [0001] The invention relates to a tail gas treatment and detection system, in particular to a vehicle tail gas detection and treatment system. Background technique [0002] The rapid development of the contemporary economy has led to the rapid development of the transportation industry, and the automobile has become one of the most important and popular means of transportation in the world. The annual production of automobiles in China has increased significantly year by year, but the technology of automobile engines is relatively backward, and the exhaust gas emissions of each vehicle are relatively large. It has caused serious pollution to our country's atmospheric environment. Therefore, the treatment and purification of automobile exhaust is particularly important. It will not only reduce the pollution to the atmosphere, but also benefit the health of the human body. [0003] The most common exhaust gas purification device is the three-way catalytic con...
