It is particularly suitable as a device that collects the condensate generated in the steam piping system and then sends the condensate to a boiler or a waste heat utilization device.

Often still has a considerable amount of heat. Therefore, in recent years, for effective use of energy, a condensate recovery system that recovers condensate and sends the condensate to a boiler or a waste heat utilization device to effectively utilize the waste heat has become widespread.

成がある。[0003] By the way, the initial condensate recovery system was connected directly from the discharge port of the steam trap to the water supply section of the boiler or the like, and pressure-fed the condensate by its own pressure. However, the initial configuration described above is sufficient when the condensate is sent to the steam trap, that is, when the pressure on the secondary side of the steam trap is high, or when the condensate is sent to a position far from the steam load. There was a problem that it could not function. Therefore, in recent years, a liquid pumping device has been used in which condensed water is once collected in a closed container, working steam is introduced into the closed container, and the condensed water in the closed container is forcibly discharged by the pressure of the working steam. Then, the condensate water is often collected. This type of liquid pumping device has a configuration disclosed in, for example, Japanese Utility Model Application Laid-Open No. 50-147228.

放されている。In the prior art liquid pumping apparatus 100, the liquid inlet 102 is connected to the vapor load via the check valve 105, and the liquid outlet 103 is connected to the waste heat utilization apparatus via the check valve 106. It The working steam inlet 108 is connected to the steam source. In the liquid pumping apparatus 100, the closed container 1
When there is no condensate in 01, the float 120 is in the lower position and the connecting plate 115 is in the lower position. Therefore, in the working steam introducing valve 110, the lifting rod 112 is lowered, and the ball-shaped valve element 122 fixed to the tip of the lifting rod 112 causes the valve seat 12 to move.
The opening of 3 is blocked. On the other hand, in the exhaust valve 111, the disc-shaped valve body 127 attached to the tip of the elevating rod 113 is
The working steam discharge port 109 is opened apart from the opening of the valve seat 128.

Then, as the amount of condensate increases, the float 120 rises, and with this, one end of the arm 118 rises. And arm 1
When 18 exceeds a certain position, the snap mechanism reverses,
The rod 121 moves up and the connecting plate 115 is lifted.

22 leaves the valve seat 123, and the working steam inlet 108 is opened. In the liquid pumping apparatus 100 of the related art, the working vapor passes through the opening of the valve seat 123, passes through the gap between the elevating rod 112 and the valve case 130, and is ejected from the opening at the lower end of the valve case 130. On the other hand, since the exhaust valve 111 is closed at this time, the pressure in the closed container 101 rises and is pushed by the pressure to discharge the condensed water from the liquid discharge port 103. In the liquid pumping apparatus 100 according to the conventional technique, the working steam is ejected from the lower end of the valve case 130 as described above, so most of the working steam directly contacts the water accumulated below.

装置は、単位時間当たりの液体圧送能力が小さいという
問題があり、液体圧送能力の向上が望まれていた。The liquid pumping device of the prior art is preferable because the condensate can be forcibly recovered by the pressure of the steam. However, in the liquid pumping device of the prior art, it took too much time for the pressure in the closed container to rise to a predetermined value after the working steam introduction valve was opened to pump the condensed water. Therefore, the conventional liquid pressure-feeding device has a problem that it takes time to pressure-feed the condensate. In other words, the conventional liquid pressure-feeding device has a problem that the liquid pressure-feeding capability per unit time is small, and it has been desired to improve the liquid pressure-feeding capability.

そのため圧送に必要な蒸気量の削減が望まれていた。In addition, the prior art liquid pumping device has a problem that a large amount of vapor is required for pumping the liquid. That is, in the liquid pumping device of the prior art, there was a contradiction that a large amount of steam was newly consumed to recover the residual heat of the condensate.
Therefore, it has been desired to reduce the amount of steam required for pressure feeding.

置を提供することを目的とする。In the present invention, focusing on the above-mentioned drawbacks of the prior art, when the working steam introduction valve is opened, the pressure in the hermetically-sealed container is quickly increased, and the liquid in the hermetically-sealed container is pumped within a short time. In addition, it is an object of the present invention to provide a liquid pressure-feeding device that consumes less steam and consumes less vapor.

た。As a result of intensive studies conducted by the present inventors in order to achieve the above object, as a result of the liquid pumping apparatus of the prior art, it takes time to pump the liquid and the amount of vapor consumption. It was found that the cause of the large number of cases was as follows.

容器内に導入された作動蒸気の多くの部分は、現実には
圧力上昇に寄与していない。That is, in the liquid pumping device of the prior art, the vapor introduced into the closed container comes into contact with the condensate therein, either directly or after repeatedly colliding with the inner wall of the container. Here, since the condensate water has a lower temperature than the working steam, the working steam is deprived of heat by the condensate and condenses to be drained. Therefore, most of the working steam introduced into the closed container does not actually contribute to the pressure increase.

される。Further, since the working steam is introduced in a state of being throttled by the opening of the valve seat of the working steam introducing valve, it will flow into the closed container at a high speed. However, as is clear from Bernoulli's theorem, if the fluid has large velocity energy, the pressure energy will be small. The working steam introduced into the closed container eventually loses its velocity energy and contributes to an increase in pressure, but it requires a considerable time in the meantime. Further, as the time elapses, the chances that the working steam comes into contact with the condensate increases, so that the problem that the working steam is drained is further increased.

装置である。The present invention has been developed on the basis of the above-mentioned findings, and a closed container is provided with a working vapor introducing port, a working vapor discharging port, a liquid inflow port, and a liquid discharging port. In the liquid pumping device that opens the working vapor inlet according to the height of the liquid level of the accumulated liquid and discharges the liquid accumulated in the closed container from the liquid outlet to the outside of the closed container, The liquid pressure-feeding device is characterized in that a deflecting plate that prevents the liquid from hitting the liquid surface is provided in the closed container.

である。Another invention for achieving the same object is to provide a closed container with a working vapor introducing port, a working vapor discharging port, a liquid inflow port, and a liquid discharging port, and collect in the sealed container. In the liquid pumping device that opens the working vapor inlet according to the height of the liquid surface and discharges the liquid accumulated in the closed container from the liquid discharge port to the outside of the closed container, there are many small gaps. A liquid pressure-feeding device comprising a vapor flow diverting member having a large total opening area, and the vapor flow diverting member covers the opening of the working vapor introducing port on the closed container side.

凝縮が防止され、導入された作動蒸気の多くが密閉容器
内の圧力上昇に寄与する。According to the first aspect of the invention, the deflection plate for preventing the working vapor from directly hitting the liquid surface is provided in the closed container. Therefore, in the liquid pressure-feeding device according to the first aspect, the introduced working vapor rarely comes into contact with the liquid surface. Therefore, in the invention described in claim 1, the working vapor is less likely to be deprived of heat by the liquid inside, the condensation of the working vapor is prevented, and most of the introduced working vapor contributes to the pressure increase in the closed container.

容器内に拡散される。According to the second aspect of the invention, the opening of the working steam introducing port on the side of the closed container is covered with the steam diverting member. Further, this steam distribution member has a large total opening area with a large number of small gaps. Therefore, the working steam introduced from the working steam introducing port into the closed container is decelerated by the steam diverting member and diffused into the closed container from a large number of small gaps at a slow speed.

ためより一層作動蒸気が液面に接触する機会が少ない。Therefore, in the liquid pumping device according to the second aspect, the velocity energy of the working vapor is converted into the pressure energy by the vapor flow diverting member. Therefore, in the liquid pumping device of the present invention, most of the energy of the vapor contributes to the pressure increase in the closed container within a short time after the working steam is introduced into the closed container. Further, in the liquid pressure-feeding device of the present invention, the velocity energy of the working vapor decreases in a short time, so that the chance that the vapor comes into contact with the liquid surface is small.
Similarly, in the liquid pressure-feeding device of the present invention, the velocity of the working vapor is small, so that the vapor in the closed container is less agitated. Therefore, there is less chance that the working vapor comes into contact with the liquid surface.

The steam diverting member 8 is provided with a deflection plate 4 on the bottom of the cylindrical ventilation part 42.
3 is attached. Here, the ventilation part 42 is made of steel mesh and has innumerable small gaps. The diameter of the ventilation part 42 is larger than that of the valve case 33. The diameter of the ventilation portion 42 need only be larger than that of the valve case 33 and is not particularly limited. However, in order to enhance the effect of reducing the speed of the working steam and smoothing it, the diameter of the ventilation portion 42 is not limited to the valve. The case 33 is recommended to be about 1.2 times to 2 times, and more preferably about 1.4 times.

This is not preferable because the resistance increases. From this viewpoint, the mesh size of the steel mesh is 30 mesh to 100 mesh.
About mesh is recommended, and most preferably about 60 mesh. As the material of the ventilation part, in addition to the above-mentioned steel net, a known material having innumerable small gaps such as punching metal and porous sintered body can be adopted.

The deflector plate 43 has no opening other than the hole through which the elevating rod 36 passes. The steam distribution member 8 is attached to cover the working steam introduction valve 6 in the closed container 2. Therefore, the opening 39 of the working steam introducing valve 6 corresponding to the opening of the working steam introducing port 12 in the closed container 2 is covered by the steam diverting member 8. Further, since the diameter of the ventilation portion 42 of the steam distribution member 8 is larger than that of the working steam introduction valve 6, there is a constant space 44 between them.

Is slightly longer than the depth of the recess 45 of the lid member 11 as shown in FIG. The width of the plate portion 46 is substantially equal to the width of the recess 45 of the lid member 11 as shown in FIG. That is, the plate portion 46 of the deflecting plate 9 has an area that almost completely partitions the concave portion 45 of the lid member 11. The plate portion 46 of the deflecting plate 9 has a working steam introduction valve 6
And there is no opening except for the holes through which the lifting rods 36, 40 of the exhaust valve 7 pass. The deflection plate 9 is fixed to the vertical wall of the inner surface of the lid member 11 at a position immediately below the working steam introduction valve 6 by a bolt 48, and the plate portion 46 is directed from the vertical wall of the lid member 11 toward the liquid storage space 14. Extends horizontally. Therefore, the working vapor introducing valve 6 is shielded from the liquid surface of the condensate by the deflecting plate 9.

First, the external piping of the liquid pumping apparatus 1 is exactly the same as that of the conventional technology, the working steam inlet 12 is connected to the steam source, and the working steam outlet 13 is connected to the steam circulation piping. The liquid inlet 15 is connected to the vapor load via a check valve (not shown) that opens from the outside toward the liquid storage space 14. On the other hand, the liquid discharge port 16 is connected to the waste heat utilization device via a check valve (not shown) that opens outward from the liquid storage space 14.

If there is no condensate in 4, float 3 is hanging to the bottom. At this time, the snap mechanism 5 is in a state in which the slide shaft 23 is lowered downward. The connecting plate 32 is pulled toward the liquid storage space 14 by the slide shaft 23, the working steam inlet 12 is closed, and the working steam outlet 13 is opened. Therefore, the liquid storage space 14 is not affected by the working vapor and has the same pressure as the load. Therefore, when condensed water is generated in the load, the condensed water flows from the liquid inflow port 15 into the liquid pumping device 1 and is accumulated in the liquid storage space 14.

The elevating rods 36, 40 connected to the slide shaft 23 are pushed in to open the working steam inlet 12 and close the working steam outlet 13. As a result, the working steam passes through the working steam inlet 12, passes through the through hole 37 of the valve case 33, and is jetted into the closed container 2 through the opening 39. Since the steam flow dividing member 8 is arranged around the working steam introducing valve 6 with a constant space 44, the working steam introducing valve 6 is provided.
The working steam jetted vigorously from the opening 39 is injected into the space 44 between the working steam introducing valve 6 and the steam flow dividing member 8, and then contacts the ventilation portion 42 of the steam flow dividing member 8.

Therefore, some of the working steam hits the ventilation part 42 and bounces off, and the space 4 between the working steam introducing valve 6 and the steam diverting member 8 is
4 is a constant high pressure atmosphere. Then, the working steam is discharged to the outside from the ventilation part 42. In the liquid pressure feeding device 1 of the present embodiment, the discharge state of the working steam at this time is that the space between the working steam introducing valve 6 and the steam diverting member 8 passes through the ventilation part 42 after a constant high-pressure atmosphere is reached. It is considerably smoothed and is evenly released over almost the entire surface area.

液面に当たることが防止される。In addition, since the total opening area of the ventilation portion 42 is sufficiently large, the speed at which the working vapor is discharged from the ventilation portion 42 is slow. Therefore, the working vapor discharged through the ventilation portion 42 has a small velocity energy and a large pressure energy. The vapor flow dividing member 8 employed in this embodiment has a gap only in the side surface portion, and the bottom has a deflecting plate 43.
Is covered by. Therefore, the working steam is not discharged downward, that is, in the direction of the condensate. Therefore, the working vapor is prevented from directly hitting the liquid surface.

First, paying attention to the working vapor discharged from the half surface of the vapor distribution member 8 on the liquid reservoir space 14 side, the vapor is horizontally discharged toward the liquid reservoir space 14.
A deflection plate 9 is provided below the vapor flow dividing member 8, and the deflection plate 9 extends from the lid portion 11 toward the liquid storage space 14 and has a sufficient length and area. Therefore, the working vapor discharged from the half surface of the ventilation portion 42 on the liquid reservoir space 14 side is not allowed to diffuse to the lower side, that is, the condensing side, and flows exclusively in the horizontal direction and the upward direction. Then, at this point, the vapor in the closed container 2 is sufficiently mixed. Therefore, the working steam discharged from the ventilation part 42 has a small chance of coming into contact with the condensate and is not vigorously stirred in the closed container 2.

出された作動蒸気と同一の経路を辿る。Next, the working steam discharged from the half surface on the lid part 11 side of the ventilation part 42 of the steam distribution member 8 will be seen. When the steam is discharged from the ventilation part 42, it immediately contacts the inner wall of the lid part 11. Then, the working steam changes its direction along the inner wall of the lid portion 11 or hits the inner wall and bounces off. Here, in the liquid pumping device 1 of the present embodiment, since the above-mentioned deflection plate 9 is attached to the vertical surface of the inner wall of the lid portion 11,
The working vapor which has turned along the inner wall of the lid portion 11 flows toward the liquid storage space 14 along the deflecting plate 9. Then, the working vapor merges with the working vapor released from the half surface on the liquid reservoir space 14 side. After that, the working steam discharged from the lid-side half surface follows the same path as the working steam discharged from the liquid reservoir space-side half surface.

Therefore, in the liquid pumping apparatus 1 of the present embodiment, the rate of condensation of the working vapor is small, and most of the working vapor contributes to the pressure increase. Further, since the working steam discharged through the ventilation portion 42 of the steam flow dividing member adopted in this embodiment has a small velocity energy and a large pressure energy, the steam is sealed within a short time. Increase the pressure in the container.

Then, the working steam in the closed container 2 is discharged to the outside from the working steam exhaust port 13.

ている。In the embodiment described above, the working steam introducing valve is mounted in the vertical direction, but the liquid pumping device of the present invention has no restriction on the mounting direction of the working steam introducing valve. Needless to say. FIG. 4 shows an embodiment in which the working steam introduction valve is attached in the horizontal direction. In the liquid pumping device 60 shown in FIG.
The deflecting plate 61 is of a cylindrical shape, one end of which is attached to the vertical portion 62 of the inner wall of the closed container, and the other end of which is open in the horizontal direction. Further, although the vapor flow dividing member 63 has the same shape as that of the above-described embodiment, the deflection plate 4
There is no member corresponding to 3, and all surfaces are made of steel mesh.

均等に排出される。The arrow in FIG. 4 indicates that the velocity of the steam ejected from the opening 66 of the working steam introducing valve 65 is high, and that a larger proportion of the working steam than in the previous embodiment directly flows through the ventilation portion of the steam distribution member 63. It is supposed to pass. When a large amount of working steam directly passes through the ventilation part of the steam diverting member 63 as shown in FIG. 4 and still has a considerable velocity energy, the working steam discharged from the steam diverting member 63 is deflected in a cylindrical shape. The collision is repeated on the inner surface of the plate 61. The working steam gradually loses velocity energy and is discharged almost uniformly from the opening side of the deflecting plate 61.

In this experiment, a liquid pumping device having a working vapor introduction valve as shown in FIG. 4 attached in the horizontal direction was used. Then, the supply pressure of the working vapor and the back pressure applied to the liquid discharge port were changed at appropriate times, and the maximum pumping amount per unit time was measured. The liquid to be pumped was water at 17 ° C. Further, as a comparative experiment, a liquid pressure-feeding device having the same shape and the same diameter, which does not have the vapor flow dividing member 63 and the deflection plate 61, was measured under the same conditions. Then, the maximum pumping amount obtained in the comparative experiment is 100
Then, the maximum pumping amount obtained by the liquid pumping device of the present example is shown by the ratio. The results are shown in (Table 1).

きる優れた効果がある。In the liquid pumping device according to the first aspect of the present invention, since the deflection plate for preventing the vapor from directly hitting the liquid surface is provided in the closed container, the introduced working vapor comes into contact with the liquid surface. There are few opportunities to do it. Therefore, in the invention according to claim 1, it is prevented that the working vapor is condensed and drained,
Most of the introduced working steam contributes to the pressure increase in the closed container. Therefore, in the liquid pressure-feeding device of the present invention, the pressure in the closed container rises quickly, and a large amount of liquid can be pressure-fed per unit time.
