Automobile tail gas purification treatment system

Abstract

The invention discloses an automobile tail gas purification treatment system. The automobile tail gas purification treatment system comprises a tail gas collection device, a tail gas purification device, a tail gas detection device and a tail gas exhaust device. The tail gas collection device comprises a reaction box. The reaction box comprises a first gas inlet pipe and a first gas outlet pipe, wherein the first gas inlet pipe and the first gas outlet pipe are connected with an exhaust pipe of an automobile. A gas pump is further fixedly arranged in the reaction box, one end of the gas pump is connected with the first gas inlet pipe, the other end of the gas pump is connected with a gas cooling box, and a gas outlet of the gas cooling box is connected with the first gas outlet pipe. The tail gas purification device comprises a coarse filtration chamber, a biological purification chamber and a chemical purification chamber. The coarse filtration chamber is connected with the first gasoutlet pipe. The tail gas detection device comprises a detection box, a second gas inlet pipe, a second gas outlet pipe and a backflow pipe, wherein the second gas inlet pipe, the second gas outlet pipe and the backflow pipe are arranged on the detection box. The second gas inlet pipe is connected with the chemical purification chamber, the second gas outlet pipe is connected with the tail gas exhaust device, and the backflow pipe is connected with the coarse filtration chamber. The automobile tail gas purification treatment system has the advantages that the cost is low, the structure is simple, and the purification effect is good.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile tail gas purification treatment system. Background technique [0002] With the acceleration of the pace of urban life, the number of cars is increasing day by day, and the problem of car exhaust has become more and more serious in recent years, and the urban air quality has been greatly affected. Therefore, the treatment of car exhaust is a very important issue at present. [0003] At present, the exhaust gas of most automobiles is directly discharged into the air without treatment, because the automobile exhaust contains harmful substances: carbon monoxide (CO), hydrocarbons (CH), nitrogen oxides (NOx), lead dust (Pb) and other substances. Air pollution, especially in large and medium-sized cities, due to the continuous increase of vehicles, the pollution caused by vehicle exhaust is becoming more and more serious, which affects people's health. The main reaso...

Problems solved by technology

[0003] At present, the exhaust gas of most automobiles is directly discharged into the air without treatment, because the automobile exhaust contains harmful substances: carbon monoxide (CO), hydrocarbons (CH), nitrogen oxides (NOx), lead dust (Pb) and other substances. Air pollution, especially in large and medium-sized cities, due to the continuous increase of vehicles, the pollution caused by vehicle exhaust is becoming more and more serious, which affects people's health

The main reasons for the ineffective treatment of automobile exhaust are as follows: first, some processing equipment requires high cost of precious metals; second, some processing equipment has complex processes and is difficult to implement; third, some processing equipment has a short service life and needs to be replaced frequently
