Under the filtration of film, most solid particles are left in vehicle exhaust, and the vehicle exhaust for flowing through ceramic filter membrane flows through
Oxidation reaction layer, reducibility gas and oxidant reaction in vehicle exhaust, the reducibility gas in vehicle exhaust are oxidized, pass through
The vehicle exhaust of peroxidization layer flows through alkaline material filled layer, and the oxidizing gas in vehicle exhaust and alkalization reducing agent are anti-
It answers, oxidizing gas is reduced, and sour gas is absorbed, and enters outlet end by alkaline material filled layer, in three-way pipe structure
Inside tube body be equipped with and can change the lug boss of airflow direction, lug boss can change airflow direction, weaken air-flow and generate
Noise；Tail gas a part is discharged from the outlet end of opening upwards, and another part of tail gas is arranged by the outlet end that Open Side Down
When out, by the outlet end that Open Side Down, venthole 901 of the tail gas first in the middle part of baffle is passed through, then under waterproof baffle
Exhaust pipe 12 that portion is set up in week is discharged, and has been achieved the third time noise reduction of tail gas, final gas with minimum sound from
Begin to rehearse tracheae.
In the section for encountering rainy weather or approach ponding, when position is lower, water will push waterproof baffle along on sliding rail
It moving, waterproof baffle is made to contact baffle, waterproof baffle is supported in baffle bottom, and exhaust pipe is sealed by baffle at this time, and stop water to flow backward,
