Environment-friendly double-layer automobile gas exhaust pipe

Abstract

The invention discloses an environment-friendly double-layer automobile gas exhaust pipe comprising an inner layer pipe body and an outer layer pipe body. A processing cavity is formed between the inner layer pipe body and the outer layer pipe body. One end of the inner layer pipe body is open, and the other end of the inner layer pipe body communicates with one end of a gas inlet pipe. The other end of the gas inlet pipe extends to the exterior of the outer layer pipe body. One end of the outer layer pipe body is sealed, and the other end of the outer layer pipe body is connected with a sealing cover. A gas suction device is arranged in the sealing cover. A filtering layer and a dust suction layer are arranged in the processing cavity. A first gas exhaust pipe body and a second gas exhaust pipe body which are mutually symmetrical communicate with the outer layer pipe body. The first gas exhaust pipe body and the second gas exhaust pipe body are fixed on the two sides of the outer layer pipe body correspondingly, and pipe openings of the first gas exhaust pipe body and the second gas exhaust pipe body are located on the front side of the outer layer pipe body. The first gas exhaust pipe body and the second gas exhaust pipe body are internally provided with inner inserting pipes and reaction grooves filled with reaction solutions. According to the overall design, tail gas exhausted by an automobile can be processed for multiple times, the minimum pollution of the final exhausted tail gas is guaranteed, exhausting paths of the tail gas can be increased through the double-layer pipe design, and the basis is provided for deep processing.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an environment-friendly double-layer automobile exhaust pipe. Background technique [0002] In recent years, with the deepening of my country's reform and opening up, the national economy has continued to develop, and the sales of automobiles are increasing rapidly. Automobiles have become our indispensable means of transportation. As of the end of 2014, the number of automobiles in my country has reached 140 million. It will reach 250 million vehicles, and the accompanying automobile exhaust has become the main source of air pollution. In my country's urban air pollution, the proportion of automobile exhaust emissions has exceeded 70%. Therefore, it is urgent to strengthen the control of automobile emissions. my country's automobile oil consumption accounts for more than 1 / 3 of the country's oil consumption, and with the increase in car ownership, my country's total automobile pollutant...

AI Technical Summary

Problems solved by technology

Although compared with developed countries, its total amount is not much, but because it is mainly concentrated in big cities, and the vehicle condition is poor, and the fuel quality is low, the pollutant emission of single vehicle is often several times higher than that of similar foreign vehicles. pose a huge threat
