Device for transferring separated gas downstream in fluid pipeline facility

Abstract

To provide a disclosure capable of transferring following obstacles to an optimum site for maintenance and inspection by an easy Venturi effect [0019], the obstacles being that: mixed gas present when pipeline-pumping a fluid conventionally; and there has been a risk of causing instrument breakage, a flow rate decrease, occasionally a physical injury, therefore, it has been obligated to mount a gas-water separator necessarily in a pipeline-pumping facility [0016]; the gas-water separator has been set physically to a piping uppermost part and has been installed over a center of a river in a case of traversing the river and over a center of a rail track ditch in a place of traversing over a railroad line [0017]; and naturally, a safe path for maintaining and inspecting the gas-water separator is required, and a weight of the path and a painting work of the path have been a burden [0018].SELECTED DRAWING: Figure 1

Description

[Technical field] This device separates the gas that is generated when a fluid is pumped through a pipe and directs it to any desired location downstream. [Background technology]

[0001] Although the invention of this application is effective for all fluids, it is written as "fluid", but it is an improvement method that is primarily intended for water supply and pressure pipe facilities. In order to distribute clean water throughout the region, it must cross many rivers, travel through railroad tracks above ground, and overcome numerous differences in elevation, all while being buried deep, or sometimes shallowly, to reach the end facilities.

[0002] In this explanation, the fluid is drinking water, but gas, in this explanation, air, is generated when the fluid is pumped through the pipes, or is mixed in from the beginning, and this can be a hindrance to pipe pumping, leading to facility breakdowns, inefficiencies, and sometimes even major accidents.

[0003] For this reason, all piping facilities are provided with automatic or manual steam separators in place to deal with this issue.

[0004] In order to separate the steam and water, due to the nature of gas, a steam-water separator is usually installed at the very top of the piping facility, and in the case of drinking water piping, a steam-water separator is installed at each apex of the piping.

[0005] In particular, with regard to drinking water, there are many cases where the pipes will necessarily cross rivers or over railway tracks. Even when the pipes are buried underground, if the top of the pipe is in a vehicle lane above the road surface, a manhole must be provided at that location, and if the pipes are above the road surface, the facility must be able to withstand the weight of passing vehicles.

[0006] When crossing rivers or railroad tracks, in order to maintain the strength of the crossing pipes and for aesthetic reasons, the midpoint is often the top of the crossing pipes. Naturally, the steam-water separator It was installed at the very top in the middle.

[0007] The steam separator installed at the midpoint requires space for its inspection, repair or replacement, and naturally, an access for workers to that space must be provided.

[0008] For other above-ground piping and piping within factories, regardless of the type of fluid, it was desirable to be able to perform maintenance and replacement work in a safe location that was lower than the top of the piping.

[0009] The proposed device follows conventional piping standards and provides only a gas reservoir (4) at the top of the piping that does not require maintenance, inspection, or consumable parts. The gas collected there can be guided to a safe and convenient location for installing an air-water separator, which is highly effective.

[0012] Dangerous maintenance and inspection work at midpoints in the air is eliminated, making it safer and eliminating the need to install an aerial work space and a work path to the aerial work space, which inevitably makes it possible to reduce the area to be painted.

[0013] No external power is required for the movement of the separation gas.

[0014] The state of air / water separation can be directly and visually inspected at any time, as necessary, using the gas vent valve (8) installed on the ground, making replacement work possible on the ground.

[0015] Even when crossing rivers or railroad tracks, only the main pipe is used, which simplifies maintenance painting work and reduces maintenance costs. [The weight of materials for the crossing water pipes is significantly reduced, lowering construction costs and shortening construction time. Hopefully.

Claims

1. The idea is to open the separated gas inlet (2) of the gas transfer pipe (1) inside the gas reservoir (4) installed at the top of the piping equipment of the fluid pressure transfer pipe (7) of the fluid pressure transfer piping facility, and install a new downstream gas reservoir (5) with a gas vent valve (8) attached to its top downstream. Just before that, the separated gas guide pipe outlet (3) of the separated gas guide pipe (1) is installed and opened toward the downstream side to generate negative pressure by the Venturi effect, and release the separated gas into the downstream air reservoir (5).

2. This piping method involves first removing the gas from a gas reservoir (4) installed at a position where gas is likely to accumulate during pressure transfer through a fluid piping, and then inserting the gas again into the fluid pressure transfer pipe (7) just before the downstream gas reservoir (6) where a gas vent valve (8) is installed, generating negative pressure in the negative pressure generating pipe (3) by the Venturi effect, releasing the gas inside the fluid pressure transfer pipe (7), re-separating the gas in the downstream gas reservoir (6), and removing it to the outside through the gas vent valve (8).
