Drainage and deodorization breathing device and inspection well

Abstract

The invention discloses a drainage and deodorization breathing device and an inspection well. The drainage and deodorization breathing device comprises a lower well lid, a water curtain nozzle arranged on the lower well lid and a plurality of deodorization water bends arranged on the lower well lid; the water curtain nozzle is arranged above the lower well lid and is connected with a water inlet pipe; each deodorization water bend comprises a vertical pipe and a bent pipe connected to the vertical pipe; the vertical pipes are arranged on the lower well lid and communicate with the upper portion of the lower well lid; the included angles between the vertical pipes and the bent pipes are smaller than or equal to 90 degrees; and the bent pipes are arranged below the lower well lid. According to the drainage and deodorization breathing device and the inspection well, the problem that odor emitted by high-concentration sewage enters the atmosphere through the inspection well lid can be solved, and the influence of malodorous gas on the surrounding environment of the inspection well is reduced; and meanwhile, the upper half part of the well can be kept clean by adding water to dilute and cool a pipeline of an underground part, so that the problem that the inspection well is polluted and damaged by digests in the pipeline is solved, the corrosion degree of the pipeline inspection well is reduced, and the service life of the pipeline inspection well is prolonged.

Description

technical field [0001] The invention relates to a sewer inspection shaft structure, in particular to a drainage and deodorizing breathing device and an inspection shaft. Background technique [0002] The inspection well is a well-shaped structure set up for inspection or dredging in the upper and lower sewers or other underground pipeline projects. The inspection well cover is installed above the inspection well; since most inspection wells are not equipped with a device for isolating odors, when high-concentration sewage passes through the sewage well A large amount of odor (hydrogen sulfide, ammonia, methane, mercaptans, hydrocarbons and other volatile organic compounds) emerges from the inspection well cover, especially in some sewage treatment plants or other places prone to odor, if the inspection well If the high-concentration sewage in the medium is mixed with other high-temperature sewage, the concentration of the odor volatilized in the sewage will become higher, an...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the defects existing in the prior art, the object of the present invention is to provide a drainage deodorizing breathing device and an inspection shaft, which can solve the problem that the odor emitted by high-concentration sewage enters the atmosphere through the inspection shaft cover, and reduces the impact of the odorous gas on the surrounding environment of the inspection shaft At the same time, it can also keep the upper part of the well clean by adding water to the pipeline in the underground part to dilute and cool down, thereby solving the problem that the inspection well is fouled by the digestate in the pipeline, reducing the degree of corrosion of the pipeline inspection well and extending the maintenance of the pipeline inspection well. service life
