A municipal sewer deodorization device and construction method

Abstract

The invention discloses a mains supply sewer deodorization device which comprises a connector internal thread pipe. A metal gasket is arranged on the side wall of the end of the connector internal thread pipe. A first connecting pipe is arranged at one end of the connector internal thread pipe, and comprises a transverse pipe, a first vertical pipe and a first bent pipe. By making the metal gasketclosely abutting against a rubber gasket on the side wall of a metal sleeve ring and sealing the joint of a sewage discharge pipe and the device, sealing performance is improved; by arranging an adjusting baffle and a rubber seal ring hinged to the inner wall of an internal thread connecting pipe, when wastewater stops being discharged, water in a water storage pipe flows down under the gravity to push the adjusting baffle to be turned over downward, so the rubber seal ring at the bottom of the adjusting baffle is attached to the inner wall of the first bent pipe to form a sealed environment,redundant wastewater is accumulated in the internal thread connecting pipe, sealing is conducted through water, and dirty gas in a sewer is prevented from flowing backward.

Description

technical field [0001] The invention relates to the technical field of sewers, in particular to a municipal sewer deodorization device and a construction method. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, Equipment, etc., all kinds of public infrastructure construction supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, such as various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity (The part outside the red line), telecommunications, heat, gas, etc., as well as the construction of squares and urban greening, etc., all belong to the category of municipal engineering. [0003] The sewer is a kind of urban public facility. This equipment appeared as early as in ancient Rome. The prototype of the modern sewer originated in Paris, Fr...

AI Technical Summary

Problems solved by technology

[0004] Common municipal engineering sewers will produce a large amount of domestic sewage, and domestic sewage will be discharged into the sewer. After a long time, it will emit an unpleasant rancid smell. The smell can easily escape out of the sewer, especially in hot summer, which is harmful to the urban environment cause serious adverse effects
