Embodiment 1

[0028] Such as figure 1 As shown, the underground rainwater / sewage pipe network bad gas prevention facility of the present invention includes two components, an air flow gravity cylinder 1 and a connecting pipeline 2. The air flow gravity cylinder 1 is a concrete cone with a height of 200 meters or more, and the diameter of the upper mouth is smaller than the diameter of the lower mouth. The air flow gravity cylinder 1 is set up vertically on the ground and can provide powerful gas suction power.

[0029] The connecting pipeline 2 is a straight or curved concrete pipe body. The straight tubular connecting pipe 2 is arranged horizontally, one end of which is connected to the opening of the bottom end side wall of the air flow gravity cylinder 1, and the other end is connected to a cone-shaped reducing connecting pipe 3. The connecting pipe 2 of the curved tube shape is arranged at the bottom of the air flow gravity tube 1, one end of which is connected to the lower port of the ai...

Embodiment 2

[0035] Such as figure 2 As shown, the basic structure of this embodiment is roughly the same as that of embodiment 1, in which the air flow gravity cylinder 1 is a concrete conical cylinder, and the connecting pipeline 2 is a number of variable diameters made of corrosion-resistant materials such as glass fiber reinforced plastics. Elbow, the upper port of the reducing elbow is set in the lower port of the air flow gravity cylinder 1, and the lower port of the reducing elbow is used to connect the underground rainwater / sewage pipe network to form a set of juxtaposed pumping gas upwards Pipeline. Among the multiple reducing elbows in this group, the lower port of one reducing elbow is connected to the proximal port of a nearby underground rainwater / sewage pipe network main line, and the lower ports of the other reducing elbows are It is connected to other main lines or branch lines of the underground rainwater / sewage pipe network in the same area through the extended connectin...

Embodiment 3

[0037] See figure 1 , figure 2 The basic structure of this embodiment is roughly the same as that of embodiment 1. Among them, the air flow gravity cylinder 1 is a cone made of corrosion-resistant materials such as glass fiber reinforced plastics, and its height is 20-40 meters; 2 is 1-2 reducer elbows made of corrosion-resistant materials such as glass fiber reinforced plastics. The upper port of the reducer elbow is set in the lower port of the air flow gravity cylinder 1, and the lower port of the reducer elbow is used to connect underground Rainwater / sewage pipe network.

[0038] The underground rainwater pipe network and sewage pipe network established in independent communities in cities and towns are self-contained pipe network systems and are not connected to the outside world. The rainwater pipe network and sewage pipe network laid underground in remote urban districts are a kind of terminal pipe network system far away from the municipal rainwater pipe network and mun...

Abstract

The invention relates to a treatment method and a prevention and treatment facility of bad air of an underground rainwater / sewage pipe network. The treatment method comprises the following steps: 1, arranging an air flow gravity cylinder, wherein the air flow gravity cylinder is vertical arranged on ground; 2, arranging a communicating pipeline, wherein the communicating pipeline is arranged at the bottom of the air flow gravity cylinder for directly or indirectly communicating the underground rainwater / sewage pipe network to the air flow gravity cylinder; 3, reconstructing a far end of the underground rainwater / sewage pipe network communicated with the communicating pipeline into an open pipeline orifice. A negative pressure type air forcible suction effect can be produced in the underground rainwater / sewage pipe network to form air directional forcible flow, so that the bad air in the rainwater / sewage pipe network is sucked and discharged into an upper atmosphere layer, the bad air is not stored or produced in the entire underground rainwater / sewage pipe network, and the potential safety hazard of burning explosion existing in the underground rainwater / sewage pipe network is also eliminated.

Description

Technical field [0001] The invention relates to an underground rainwater / sewage pipe network, in particular to an underground rainwater / sewage pipe network bad gas treatment method and prevention facilities. Background technique [0002] The underground rainwater / sewage pipe network is a city's sewage and rainwater discharge system. It is a basic component of a city's functions and an important part of a city. The operation of underground rainwater / sewage pipe network is directly related to the ecological environment and city image of a city, and directly affects the daily life of urban residents. The sewage collected through the underground rainwater / sewage pipe network is discharged after treatment to meet the standards, which can avoid the random discharge of sewage, thereby protecting the living environment of urban residents and the health of urban residents. [0003] The underground rainwater / sewage pipeline network generally includes main lines, branch pipelines, and micro ...
