Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for separating gas from a liquid flowing in a pipe.

When gas gets mixed into the pipes through which liquid flows, various problems occur.

For example, in hot water heating pipes, the heating efficiency is significantly reduced, and in the case of water pipes, water hammer occurs when water flows out from the water outlet at the end.

For this reason, conventionally, an exhaust valve is installed in the middle of the pipe to discharge the gas outside the pipe.Since gas cannot be easily separated from the flowing liquid, a gas-liquid separator is also used. .

However, conventional gas-liquid separators do not separate gases sufficiently, and have little effect, especially when the flow rate is high.

Fig. 1 shows an example of a conventional gas separation device, in which when an inclined baffle plate 2 is provided in a pipe line 1, gas and liquid are separated immediately after the baffle plate 2. This is an application of separation, and as shown in FIG. 1, a Nijiya 1 plate 2 is simply provided, and a gas-liquid separation chamber 3 is provided immediately after it.

Since the gas separated from the liquid has pressure, it is discharged from the pipe through an exhaust valve connected to the attachment port 4.

However, as described above, this device does not separate the gas sufficiently, and the separated gas flows out toward the outlet together with the liquid.

In view of the above problems, the purpose of the present invention is to improve the conventional product so that sufficient gas-liquid separation occurs.

The configuration for achieving the purpose of the present invention is as follows.

In order to restrict the flow path downstream of this resistance plate by arranging one resistance plate with a length larger than the inlet diameter opposite the inlet in the main body that has a cross-sectional area sufficiently larger than the cross-sectional area of the pipe. The tip of the inclined plate is bent upward to form a substantial cross-shaped plate, and a gas reservoir is provided above the main body to protrude from the flow path, and an exhaust valve is installed above the gas chamber. It is something.

Therefore, the present invention does not only utilize the fact that gas is separated behind the resistance plate, but also makes use of the principle of increasing the cross-sectional area of the flow path and directing the overall flow direction from the inlet at right angles. At the same time, the flow path is deflected by an inclined L-shaped plate installed on the exit side, so that the liquid flows from top to bottom and reaches the outlet. A difference is created in the pressure distribution within the fluid to facilitate gas separation, and the separated gas is captured in the gas reservoir chamber.

The structure and operation of the present invention will be explained in detail below according to the embodiments shown in the drawings.

FIG. 2 shows an embodiment of the present invention.

The main body 10, which has an inlet 11 and an outlet 12 connected to the pipe, has a cross-sectional area sufficiently larger than the cross-sectional area of the pipe, and has a gas storage chamber 16 projecting upwardly, and an exhaust valve 1 above it.
7 is installed.

Inside the main body 10, a resistance plate 13 is disposed facing the liquid inlet 11, and on the downstream side of the resistance plate 13, an L-shaped inclined plate 15 for restricting a flow path with an upwardly bent tip is provided. An auxiliary plate 14 is provided below the gas storage chamber 16.

Although the tip of the inclined plate 15 is shaped like a box in this embodiment, it is sufficient that it is bent substantially into a box.
A deformed shape or a five-character shape is also possible, and can be appropriately deformed depending on the size of the main body 10.

Therefore, the operation in this embodiment is as follows.

When liquid mixed with gas flows into the inlet 11 of the main body 100 in the direction of the arrow, the flow velocity is reduced due to the resistance plate 13 and the enlargement of the channel cross section, and the direction of the flow is changed upward.

Therefore, when the flow velocity decreases, the gas mixed in the liquid floats upward due to buoyancy, and since the flow has changed upward, this effect is added and the gas is separated.

After this, the flow flows from above to below, so the buoyant gas floats up or circulates against this flow.

The separated and floated gas is captured in the gas storage chamber 16, and the gas is removed from the exhaust valve 1.
7 to the outside of the tube, but the gas that is not separated and flows together with the liquid moves upward as shown by the dotted arrow due to the difference in pressure distribution caused by the inclined plate 15 provided behind the auxiliary plate 14, that is, the liquid refluxes. occurs around the auxiliary plate 14,
Since the gas collects in the gas storage chamber 16vc, no gas flows to the outlet 12 located downstream of the inclined plate 15.

The force at the tip of the inclined plate 15 (because it is shaped like a single character, the liquid flow is lifted upward, a reflux is generated, and the separated gas moves upward.

FIG. 3 shows another embodiment of the present invention, in which parts having the same functions as those in FIG. 2 are given the same numbers.

In the embodiment shown in FIG. 3, the inlet 11 is provided vertically.

The main body 10 has a comb whose cross-sectional area is sufficiently larger than the cross-sectional area of the pipe, as shown in FIG.
It has 17 exhaust valves above it.

A resistance plate 13 is disposed at a position facing the inlet 11, and an inclined plate 15 whose tip is substantially [shaped] is provided on the downstream side thereof.

The effect of this embodiment is similar to that shown in FIG. 2. The flow direction of the gas-containing liquid whose flow path is changed by the resistance plate 13 is such that the gas separates and floats, and the separated and floated gas flows into the gas storage chamber 16.
rc concentrates and is then discharged outside the pipe through an exhaust valve 17.

However, the gas separated here and flowing together with the liquid has its flow path restricted by the inclined plate 15 with an upwardly shaped tip and moves in the direction indicated by the dotted arrow 5, and finally concentrates in the gas reservoir chamber 16, where the gas Only the liquid containing no gas flows out from the outlet 12, thereby eliminating the adverse effects of gas contamination.

As explained above, the present invention changes the direction of the flow of liquid flowing in from the inlet at right angles, reduces the flow velocity by expanding the flow channel cross section, and makes the subsequent flow from top to bottom. The slanted plate creates a circular flow within the main body, allowing even fine gases to be sufficiently separated.

Because of this structure, it can exhibit great effects even at high flow rates, especially in large-scale hot water circulation devices.
