Multistage screen type automobile tail gas collecting device

Abstract

The invention discloses a multistage screen type automobile tail gas collecting device. The multistage screen type automobile tail gas collecting device comprises a gas inlet pipe, a reaction box, an inclined partition plate, tail gas collecting liquid, multistage screens and an exhaust port. The automobile tail gas collecting device is simple in structure and simple and convenient to operate and guides automobile tail gas from a tail gas pipe to the tail gas collecting liquid in the reaction box for collection and absorption, hazardous substances in the automobile tail gas finally discharged to the atmosphere are greatly decreased through treatment of the multistage screens, air pollution is reduced, the urban PM 2.5 content is reduced, and the automobile tail gas collecting device is beneficial to health of people. In addition, the special tail gas collecting liquid is adopted to conduct chemical absorption on the automobile tail gas, the content of specific substances in the tail gas collecting liquid is detected, a method for rapidly judging whether the operating situation of an automobile engine is normal or not can be provided so as to facilitate fault analysis and later-period repair of the automobile engine, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of automobile environmental protection, in particular to a multi-stage screen type automobile exhaust gas collection device. Background technique [0002] The automobile industry has developed rapidly since the second industrial revolution in the 19th century. In modern society, automobiles have become an indispensable means of transportation, and with the continuous improvement of people's living standards, there are more and more household vehicles. A large number of automobiles have brought great convenience to the society and people, but they have also caused environmental problems such as automobile exhaust pollution. Therefore, it is necessary to collect, detect and treat the harmful components in these gases. [0003] In addition, automobile exhaust is the product of direct combustion of gasoline in automobile engines. The composition and content of automobile exhaust can directly reflect the internal working...

AI Technical Summary

Problems solved by technology

[0004] Existing devices and technologies for collecting automobile exhaust are relatively few, and there are significant shortcomings such as relatively complicated, poor operability, and low absorption efficiency for automobile exhaust. The automobile exhaust absorption device has very important application value and practical significance
