FIG. 12 shows a piping device for discharging the drain accumulated in a general container, and FIG. 13 is a diagram showing a behavior at the time of discharging the internal fluid. However, here, there is no particular limitation on the method of flowing the liquid into the container and the type of the container,
Since it is a device that drains drain such as water,
The shapes and sizes of the container 1 and the inlet pipe 2 shown in FIG. 12 are not limited to this figure, and are shown for convenience of description.

流路閉塞が起こる様子を以下に詳しく説明する。In such an apparatus, it is known that an unstable phenomenon occurs during drain flow at the opening of the outlet pipe 3 shown in FIG. That is, when the flow rate exceeds a certain level, an unstable phenomenon such as blockage of the flow path of the outlet pipe 3 appears. The manner in which this flow path blockage occurs will be described in detail below.

る。FIGS. 14, 15 and 16 are enlarged views from the bottom surface of the container 1 of FIG. 12 to the outlet pipe 3. When the liquid in the container shown in this example is drained and discharged, it is a prerequisite that the drain in the container does not have much water level. Further, it is a condition to handle a so-called gas-liquid two-phase flow in which a gas flow and a liquid flow simultaneously exist.

し、容器１内部に達する。FIG. 14 shows the flow of the outlet pipe 3 when the drain flow rate is small and a stable flow is maintained. The flow of drain is shown by a thin arrow 4 and the flow of gas is shown by a thick arrow 5. The drain forms a liquid film on the inner wall surface of the outlet pipe 3 and flows downward, while the gas passes through the center of the liquid film and rises to reach the inside of the container 1.

示している。FIG. 15 shows an initial stage where instability appears in the flow as compared with the state of FIG. As the flow rate increases, the drain also increases the inflow velocity into the opening of the outlet pipe 3 and flows in a trajectory that just closes the opening. Thereby, the gas reaches the container 1 by passing through a slight gap formed in the opening or directly passing through the inside of the drain. Here, when the gas passes through the drain, the gas causes a large buoyancy against the drain, so that the drain makes it difficult for the drain to flow downward. In the figure, h1 represents the drain water level of the container 1.

ンは下方にかけて流れにくくなる。FIG. 16 illustrates a situation in which the flow rate is further increased and the opening is blocked. This occurs because the draining force generated by the gravity g of the drain and the buoyancy f generated by the gas are balanced, and the drain becomes less likely to flow downward.

返すことになる。FIG. 17 shows a state in which the opening of the outlet pipe 3 is closed. When this closed state occurs, the drain does not flow from the opening of the outlet pipe 3, so that a closed portion P indicated by diagonal lines is formed and a water level is generated inside the container 1. The rate of rise of the water level varies depending on the capacity of the container 1, but the liquid level 1 is formed by the drain accumulated in the container 1. As shown in FIG. 18, when the water level h2 of a certain stage is reached, the balance of the closed state is broken by the pushing pressure of the head of the water level h2 that is applied to the closed portion P, and the drain is again discharged from the outlet pipe 3 as shown in FIG. run down. However, the closed portion P shown in FIG. 17 is immediately generated in the opening portion of the outlet pipe 3, and the same operation as in FIGS. 18 and 19 is repeated.

らない。As described above, in the conventional device, the flow of the drain is not stable at the opening of the outlet pipe 3, and such a device is applied to a place where a stable flow is required. I can't. For example, a steam header of a moisture separator used in a nuclear power plant is an example where a stable flow is required. Here, the drain flows downward from the steam header to the outlet pipe, but if a blockage is formed at the opening of the outlet pipe, a water level as shown in Fig. 18 is generated there, leading to the steam header. The heat transfer tube for heat exchange is submerged in the drain, and heating steam cannot be sent into the heat transfer tube. That is, in such applications, the formation of drain water level is a problem and must be avoided.

There is also one that uses a means for maintaining a constant water level on the bottom surface in addition to connecting (see, for example, Japanese Utility Model Publication No. 2-13351).

There is a need for a new method.

る。A piping device according to the present invention (claim 1) is a drain which flows downward from a container through an intermediate path from the container to the outlet pipe, and a gas which rises in the outlet pipe and flows into the container. It is characterized in that it is constituted by a plurality of gas-liquid separators which separate and guide by the gravity.

の流体を分離させるようにする。In the present invention, the unstable flow of the drain in the outlet pipe causes the rise of the water level in the container.
Even if the drain flow becomes unstable, the main purpose is to prevent the effect of the rise in the water level from reaching the container.The intermediate path from the container to the outlet pipe is composed of a gas-liquid separator. To do. In addition to keeping the water level rise in the range of the gas-liquid separation section, both fluids are separated in the gas-liquid separation section in order to stabilize the flow of drain as much as possible.

不安定に陥るのを防止するようにする。For separating the gas and liquid, for example, a complicated means can be incorporated, but as a very simple method, the separation of the gas and liquid is achieved by gravity so that both fluids flow in their respective paths without interference. This can be achieved by, for example, inclining each gas-liquid separation section at a constant angle. In this way, normally, the drain and gas are separated in the gas-liquid separation unit, and even if the drain is clogged in the outlet pipe, the rise of the water level due to the drain is stopped in the gas-liquid separation unit, and the flow of the drain is impaired. Try to prevent falling into stability.

The drain that has flowed into the container 11 flows on the bottom surface as shown by the arrow 4 toward the inlets of the gas-liquid separation units 13a and 13b. The drain flowing to the center of the container 11 is the gas-liquid separating parts 13a and 13b.
At the entrance of the gas-liquid separation plate 16, the outer surface of the gas-liquid separation plate 16 is collided and divided into two directions along the outer surface.
It flows into a and 13b (see FIG. 3 (a)). At this time,
In the gas-liquid separation parts 13a and 13b, the gas rising from below flows into the container 11, but since it flows near the inner surface of the gas-liquid separation plate 16 as indicated by the arrow 5 in FIG. 3 (a). The gas does not interfere with the drain, and the rising gas does not impede the flow of the falling drain.

The drain that has passed through a and 13b interferes with each other, and the drain becomes stagnant as shown in FIG. At this time, a drain water level is formed in the gas-liquid separation portions 13a and 13b above the closed portion P due to the growth of bubbles.

抑えることができる。The pushing pressure acting on the closed portion P of the present embodiment can be applied up to the maximum water level h4 beyond the head at the water level h3 shown in FIG. 4, and the closed portion P is easily broken by this head and the drainage is drained. Flows downwards. Due to this flow, the stagnation of drain is eliminated, and the occurrence of unstable flow can be suppressed.

Therefore, the water level is not formed in the container 11.

After that, the gas flows through the gas-liquid separating parts 13a and 13b into the container 11, and during this period, the drain and the gas do not interfere with each other (see FIG. 3A).

Drains flowing from two directions in 13b collide with each other at a confluence j and interfere with each other, so that the flow of the drain becomes unstable, which may cause a new problem. The embodiment shown in FIGS. 5 and 6 is effective in solving the above-mentioned problem at the junction j. That is, as shown in FIG. 5, the gas-liquid separating portions 13a and 13b are provided with guide vanes 17 in addition to the short pipe 15 and the gas-liquid separating plate 16 of the above-described embodiment. This guide vane 17 is shown in FIG.
As shown in (a) and (b), two vanes 19 are provided on the outer periphery of the thin tube 18. The vane 19 is arranged at a position that divides the circumference into two equal parts. Gas-liquid separation parts 13a, 13b
To install the guide vanes 17 on the above, the plane of the vanes 19 is arranged so as to face the direction of the drain drop.

In this way, since the drains do not directly collide with each other, mutual interference can be avoided and a stable flow state can be maintained. At this time, the gas rises while passing through the inside of the thin tube 18, and no interference occurs with the drain. Therefore, the rising gas does not hinder the flow of the falling drain. As described above, in the present embodiment, the gas flow and the drain flow are more reliably separated, and the drain flow can be prevented from becoming unstable.
