It is mainly used for temporary storage of garbage, and then regularly transferred to large garbage treatment stations or landfills by garbage trucks such as garbage transfer trucks. The kitchen waste in the garbage station is easy to ferment inside and form a strong odor. The garbage station will be equipped with negative pressure equipment for exhaust and deodorization to avoid the garbage station from emitting odor and ensure good use effect. When the negative pressure equipment is exhausting, it needs to be exhausted through the exhaust pipe.

In addition, ordinary exhaust pipe bodies cannot intercept gas in one direction, and are prone to odor, resulting in poor use effect. Based on this, the utility model designs a negative pressure exhaust pipe for garbage stations to solve the above problems. Utility Model Content
