Description

Technical Field

[0001] The utility model relates to the technical field of deodorization of urban drainage pipes, in particular to a deodorization device for urban drainage pipes. Background Art

[0002] Urban drainage pipes collect and discharge sewage, wastewater and rainwater, as well as discharge dirt and sewage from sanitary equipment outside buildings. After searching, the prior art (Announcement No.: CN202321279565.9) is a sewage pipe deodorization device. The article records that "through the exhaust pipe and water guide cover, the outside water enters the water guide cover through the water permeable hole, and the water enters the inside of the water pipe along the inner wall of the water guide cover. When the gravity of the water pipe plus the gravity of the water is greater than the elastic force of the spring, the water guide cover slides down along the exhaust pipe, causing the water outlet to leak out of the bottom surface of the deodorization pipe. At this time, the water in the water pipe The water flows into the pipe body to realize the drainage operation. After the drainage is completed, under the elastic force of the spring, the water guide cover rises to make the water outlet hole contact with the deodorization pipe to realize the sealing of the water holding pipe. When exhausting, the gas in the pipe body enters the exhaust pipe, and the gas contacts with the activated carbon filter bag and is discharged from the through groove. The deodorization operation is performed after being filtered by the activated carbon filter bag to avoid the odor in the pipe body from affecting the outside world. However, in the prior art, the water outlet hole of the water holding pipe has a slow drainage speed, which leads to the problem that when the sewage is easily in contact with the activated carbon filter bag, the deodorization effect on the gas in the pipe is affected.
