Abstract

The invention discloses a tail gas collecting device and relates to the technical field of automobile tail gas collection. The tail gas collecting device comprises a chamber and a tail gas exhaust fan assembly. The tail gas exhaust fan assembly is composed of a centrifugal fan and an air pipe. An air feeding port of the centrifugal fan is flexibly connected with an air inlet of the air pipe. The air pipe is arranged at the top of the two sides in the chamber. An air outlet of the air pipe is exposed out of a roof of the chamber. A door hole which is through forwards and backwards is formed in the chamber. The air pipe is provided with multiple suction openings. Each suction opening is provided with an inserting plate. An air curtain machine is arranged at the top of the door hole. Air-inlet grilles are arranged on the two sides of the lower portion of the chamber. Compared with the prior art, the tail gas collecting device is simple in structure, good in tail gas collecting effect, high in universality and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust gas collection, in particular to an exhaust gas collection device suitable for the first start-up station of an engine in a commercial vehicle assembly workshop before the vehicle is rolled off the assembly line. Background technique [0002] The off-line station of the commercial vehicle assembly workshop needs to start the vehicle for the first time and drive it off the assembly line. The vehicle that starts for the first time will emit exhaust gas containing a large amount of harmful substances, such as: carbon monoxide, nitrogen oxides, sulfur dioxide, soot particles (containing heavy metals Compounds, lead compounds, etc.); The problem of exhaust collection and emission at the first start-up of the commercial vehicle off the assembly line has been plagued by major commercial vehicle manufacturers in China. All parties are also constantly trying various methods, but all have worked ...
