Problems solved by technology

[0006] 1) The resistance loss of the pipeline is large, resulting in the maximum collection radius of the vacuum station being much smaller than the single-phase transportation of pure liquid phase transportation;
[0007] 2) A large amount of gas enters the vacuum conveying pipeline and finally reaches the vacuum sewage storage tank, causing the vacuum pump to start frequently

Embodiment 1

[0057] The invention discloses a pure liquid phase flow negative pressure drainage system, which is suitable for the collection and treatment of urban and rural domestic sewage, such as figure 1 As shown, it includes multi-point distributed negative pressure fluid collection wells 1 and a vacuum station 2 connected to the negative pressure fluid collection wells 1 through a negative pressure delivery pipeline 300 . Negative pressure fluid collection wells 1 are respectively buried under the ground of single-family residences in cities and towns or rural areas. Negative pressure fluid collection wells 1 are connected to user septic tanks through sewage confluence pipeline 101; The pipeline opening and closing control device 11 for well 1 and vacuum station 2 on-off; The upper part of the tank 3 is connected, and the negative pressure fluid collection tank 3 communicates with the vacuum pump 4 through the gas delivery pipe 301 at its top. Through the fluid pipe 302 to the targe...

Embodiment 2

[0071] Embodiment 2 of the present invention has the same structure as Embodiment 1, but when applying the negative pressure pipeline opening and closing device provided by the present invention, it is necessary to determine the volume and weight of the floating block 1111 used according to the density of the liquid to ensure that the first floating block 1113 The buoyancy ρ received by the buoyant member 111 when it is completely submerged under the liquid surface and the liquid surface does not reach the second floating block 1114 液 wxya 下max greater than the total gravity of the buoyant element 111 and the blocking element 112 and equal to the sum of the total gravity of the buoyant element 111 and the blocking element 112 and the negative pressure suction, while ensuring that the buoyant element 111 is under pressure when the entire buoyant element 111 is completely submerged under the liquid surface buoyancy ρ 液 wxya max It is greater than the sum of the total gravity a...

Embodiment 3

[0074] Embodiment 2 of the present invention has the same structure as Embodiment 1, but when applying the negative pressure pipeline opening and closing device provided by the present invention, it is necessary to determine the volume and weight of the floating block 1111 used according to the density of the liquid to ensure that the first floating block 1113 The buoyancy ρ received by the buoyant member 111 when it is completely submerged under the liquid surface and the liquid surface does not reach the second floating block 1114 液 wxya 下max greater than the total gravity of the buoyant element 111 and the blocking element 112 and less than the sum of the total gravity of the buoyant element 111 and the blocking element 112 and the negative pressure suction, while ensuring that the buoyant element 111 is under pressure when the second floating block 1114 is partially submerged under the liquid surface buoyancy ρ 液 gV is greater than the sum of the total gravity and negativ...

Abstract

The invention relates to the technical field of liquid discharge, and discloses a pure liquid phase flow negative pressure liquid discharge system. The pure liquid phase flow negative pressure liquiddischarge system comprises negative pressure fluid collection wells which are distributed in a multi-point mode and a vacuum station communicating with each negative pressure fluid collection well, and the negative pressure fluid collection wells are provided with sewage confluence pipelines accessing to users; and the pure liquid phase flow negative pressure liquid discharge system is characterized in that pipeline opening and closing control devices for controlling the connection and disconnection of the negative pressure fluid collection wells and the vacuum station are arranged in the negative pressure fluid collection wells, the pipeline opening and closing control devices comprise buoyancy parts and blocking parts linked with the buoyancy parts, and the blocking parts are always located below the liquid level. According to the provided pure liquid phase flow negative pressure liquid discharge system, a pure liquid phase flow is adopted to replace existing multi-directional flowtransportation, the pipeline resistance is reduced, system energy consumption is lowered, and the collection radius is increased; and the pipeline opening and closing control devices of pure mechanical structures are adopted to replace existing electric control valves, the engineering cost is lowered, maintenance is convenient, and the life of the system is prolonged.

Description

technical field [0001] The invention relates to the technical field of liquid discharge, in particular to a pure liquid phase flow negative pressure liquid discharge system. Background technique [0002] In cities and densely populated areas, gravity pipelines are often used to collect sewage. The sewage in the building flows into the outdoor inspection well. The sewage pipeline is laid according to a certain slope. The sewage is transported along the pipeline to the sewage lifting well by gravity, and then pumped Stations are elevated to sewage treatment facilities. [0003] With the acceleration of my country's urbanization process, the pressure of sewage treatment in small towns and rural areas is also increasing, and the locations of residents in many villages and towns are relatively scattered, especially in the case of large changes in rural terrain and many rivers. If relying on traditional The gravity pipeline collection method is more difficult for pipeline laying a...
