Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional apparatus such as a gas-liquid pump for separating a mixed gas-liquid flow into gases and liquids lacking an automatic water level adjuster may cause the water level to be frequently formed closer to the upper end or the lower end within the apparatus and the phenomena to frequently occur that after separation gases are mixed again with liquids or liquids are mixed again with gases and pulsating occurs, and that since models differ depending on the use in water or the use on land, such conventional separators are not useful, lack in practicality, keeps such gas-liquid pumps out of widespread use, and therefore have narrow application range, for example. <P>SOLUTION: The amphibious gas-liquid separator is provided with apparatuses automatically controlling the flow rates of gases and liquids specifically by providing a liquid opening and closing apparatus and a gas opening and closing apparatus, which automatically interfacing with a float within a sealed container. Thus, the float moves upward and downwards so that the water level is not formed mainly on the upper or lower end, sucking property, suction, and frictional force remain unaffected, gases and liquids are not mixed again after separation, and no pulsation occurs. Furthermore, the separator can be used in water, on water, and on land. Furthermore, gas-liquid separation functions of the separator are more completely exerted, so that the application ranges of gas-liquid pumps are increased. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  A gas-liquid mixed phase flow is separated into a gas and a liquid to form a pressure gas and a pressure liquid, and each is pumped to an application field. In particular, by completely separating the gas-liquid mixed flow of the gas-liquid pump into the pressure gas and the pressure liquid, it is possible to pioneer a new field of use for easily obtaining the pressure gas in a field that requires a conventional blower or compressor.

In many cases, the amount exceeds the amount, and gas-liquid separation produces many uses. The present invention performs this separation work, and after passing through the land-based universal gas-liquid separation device of the present invention, the liquid is free of bubbles. Since it becomes high-concentration dissolved oxygen water, it can be used in the fields of water purification, seafood culture, and hydroponics.

  Furthermore, it can be used as high-concentration dissolved oxygen water without bubbles, and can be used to improve the water quality (elimination of oxygen deficiency) in the closed layers of rivers, ponds and dams.

  Furthermore, in gas-liquid separation of gas-liquid pumps, gas enters the field of conventional compressors and blowers as compressed gas. It can be easily used in various fields such as underwater no-pollution drilling, sludge removal such as fish farming and fish excrement.

Japanese Patent No. 3341111 (Deep Bottom Resource Suction Lifting Device) describes a gas-liquid separation device in water as a device for separating gas-liquid in a gas-liquid two-phase flow from a gas-liquid pump. Furthermore, as a device for separating gas-liquid in a gas-liquid two-phase flow from the gas-liquid pump, there is a description in Japanese Patent No. 3460053 (water bottom bubble drilling device), and there is a gas-liquid separation device in water.

Until several years ago, there were water drainage in the gas pressure pipe, air vent in the water pipe, water tank and air tank drain, and air vent, but a full-fledged gas-liquid mixed flow was used as a gas-liquid separation device There is no active device.
There is a full-fledged gas-liquid mixed flow (gas-liquid two-phase flow) pumped from a gas-liquid pump that has recently appeared, but the application is small as it is, and the application is greatly expanded by complete gas-liquid separation. It is in the development of a reliable land and water free gas-liquid separator.

  Since the advent of gas-liquid pumps, the need for gas-liquid separators has increased. In-water gas-liquid separators are described in part of Patent Nos. 3341111 and 3460053, but are limited to water. The present invention, which is inconvenient, lies in the development of a simple and reliable land-free gas-liquid separator.

  Although there has been a device for gas-liquid separation of a gas-liquid mixed flow (gas-liquid two-phase flow) from a conventional gas-liquid pump, its function is not sufficient, practical use has been delayed, and the utility value is as it is The application of the present invention is greatly expanded by completely separating gas and liquid, which has been small, and the present invention lies in the development of a simple and reliable practical land-based gas-liquid separator.

  Furthermore, in the present invention, the conventional gas-liquid separator cannot automatically adjust the internal water level, the water level easily reaches the upper end and the lower end, and gas and liquid are frequently mixed again in the air supply pipe and the water supply pipe. The present invention resides in the development of an apparatus that solves this problem, which frequently occurs when the role of gas-liquid separation cannot be fulfilled.

  The conventional gas-liquid separator has been required to be installed in water, but the present invention lies in the development of an apparatus that can exhibit the separation function both on land and in water.

  Furthermore, this invention exists in development of the apparatus which can exhibit a gas-liquid separation function even if it installs in the depth of shallow water.

  Furthermore, the present invention has a gas-liquid separation function in which the gas level in the liquid supply pipe does not fluctuate automatically after the gas liquid is separated, and the liquid does not enter the liquid supply pipe or the liquid again in the air supply pipe. In the development of equipment.

  In the conventional gas-liquid separator, when the length of the air supply pipe and the length of the liquid supply pipe vary greatly, or depending on the discharge position of the air supply pipe and the discharge position of the liquid supply pipe, the fluctuation of the internal water level 13 is smooth. Unable to cope, the water level 13 is shifted to one side of the upper and lower sides, the occurrence of pulsating flow (flow that is unilaterally shifted unilaterally) frequently occurs, and gas or The present invention resides in the development of a device that does not cause pulsating flow in the event that the liquid is mixed again.

  Furthermore, the present invention lies in the development of a device that is less likely to be adjusted or broken down by adopting a simple pipe-based component configuration.

  Furthermore, the present invention can always smoothly perform the suction force, suction force, and frictional force without affecting the vertical vertical displacement of the float 8 even when the liquid supply port opening / closing device 9 and the air supply port opening / closing device 10 automatically open and close. The development of a device that can be opened and closed automatically.

  In order to solve the above-described problems of the conventional gas-liquid separator, the present invention provides an inlet for an injection pipe 2 for injecting a mixed flow of gas and liquid from the outside into the sealed container 1 as described in claim 1. 3, a liquid feed port 4 is provided in a liquid feed pipe 4 for automatically pumping liquid from the lower part in the sealed container 1, and an air feed pipe for automatically pumping gas from the upper part in the sealed container 1 to the outside. 6, the air supply port 7 is provided, and the airtight opening 1 is provided with a float 8 that automatically displaces 13 in accordance with the fluctuation of the water level 13. As the above-described configuration that is attached and interlocked with the float 8, when a gas-liquid mixed flow is injected from the outside into the sealed container 1, the gas is separated into the upper part and the liquid is temporarily separated into the lower part, and the liquid is sent in the lower part. It is automatically pumped from the port 5 to the outside through the liquid feed pipe 4, and the gas is at the top. When the float 8 is lowered to the lower part due to the drop in the water level 13, the liquid supply port 5 is automatically reduced and closed, and the amount of liquid delivered is reduced. When the float 8 is displaced upward with the water level, the air supply port 7 is automatically reduced and closed, and the air supply amount is reduced and automatically controlled. The liquid supply port 5 and the air supply port 7 Since the water level 13 always keeps near the middle without reaching the extreme upper and lower ends, the gas and the liquid are completely separated and pumped to the outside. is there.

  Furthermore, the present invention is characterized in that either one of the liquid supply port opening / closing device 9 and the air supply port opening / closing device 10 is installed as described in claim 2.

  Further, according to the present invention, as described in claim 3, one or both of the liquid supply port opening / closing device 9 and the air supply port opening / closing device 10 are cylindrical, and the shutter moves up and down the liquid supply port 5 or the air supply port 7. It is characterized by opening and closing.

  The cylindrical shutter according to claim 3 is a case where the liquid supply port 5 and the air supply port 7 provided on the side surfaces of the liquid supply tube 4 and the air supply tube 6 are opened and closed as shown in FIGS. 1, 4 and 7. A liquid opening / closing device 9 (pipe configuration) and a gas opening / closing device 10 (pipe configuration) having an inner diameter very close to the outer diameter of the liquid feeding pipe 4 and the air feeding pipe 6 are provided and moved up and down in conjunction with the float. 5. A device that opens and closes the air supply port 7. In this case, the shutter effect (opening / closing effect) is enhanced by making the outer diameter and the inner diameter extremely close to each other. FIG. 3 is an example provided inside, and FIGS. 2, 5, 6, 8, and 9 are outside. This is an example provided.

The best configuration example in the present invention is the configuration shown in FIG. 4, and FIG. 5 and FIG. 6 show the details of the important parts, that is, the liquid delivery port 5 shown in FIG. Since a plurality of pipes are provided at the same interval and the pressure from the periphery of the pipe cross section is always balanced, the suction force and suction force at the liquid delivery port 5 are not erased from each other, so the pressure increases or decreases. However, the frictional force does not increase or decrease, and the float can be moved up and down without any effect on the frictional force between the liquid feeding pipe 4 and the liquid opening / closing device 9 even in water, air, high pressure, and low pressure, as shown in FIG. Since the air supply port 7 has the same configuration, no suction force or suction force occurs between the gas opening / closing device 10 and the increase in frictional force is eliminated. However, when the gas-liquid separator is used in water, buoyancy occurs, so a weight may be provided.
As described above, the float can be moved up and down without the influence of the liquid feeding port and the air feeding port, the water level in the sealed container 1 does not reach the extreme upper and lower ends, the gas and liquid are completely separated and pulsated (one intermittently It is a land-and-water gas-liquid separator that can always automatically form water levels without producing a natural flow.

Normally, it is easy to devise a gas-liquid separator using a float,
(1) No machinery,
(2) It is a simple pipe structure,
(3) Whether under high pressure or low pressure
▲ 4 ▼ Underwater or on land
(5) Pulsation does not occur even if there is a difference in the extension of the liquid supply pipe and air supply pipe.
(6) There is no influence of suction force, suction force, friction force,
The feature of the present invention is that the automatic vertical movement of the float 8 can be smoothly performed.

  According to the experimental results of the prototype of the land-and-water universal gas-liquid separator of the present invention using the gas-liquid pump, the “sucking force”, “suction force” and “friction force” have no effect on the vertical fluctuation of the float 8 and are completely The gas-liquid was separated and a flow without pulsation was created, and it was confirmed that the float 8 easily and automatically fluctuated up and down. This technique is the most emphasized point of the present invention, and does not use any machinery, and enables a gas-liquid separation function while automatically adjusting with a simple pipe construction main body.

Further, according to the present invention, as described in claim 4, the float 8 is installed along with any one or a plurality of the injection pipe 2, the liquid supply pipe 4, and the air supply pipe 6, and the liquid supply pipe 4 The air supply pipe 6 functions as a rail of the vertical displacement of the float 8 and can be smoothly interlocked vertically, and is characterized in that the liquid supply port 5 and the air supply port 7 can be easily opened and closed automatically.
[FIG. 1] is an example diagram in which a float 8 is installed along with a liquid feeding tube 4 and an air feeding tube 6 [FIG. 4] is an example diagram in which a float 8 is installed along with a liquid feeding tube 4 and an air feeding tube 6 [FIG. 7] is an example in which the float 8 is installed along the injection pipe 2 and the air supply pipe 6.

Further, according to the present invention, the land-and-air free-standing gas-liquid separation device is generally preferably configured such that the hermetic container 1 is formed in a vertically long cylindrical shape, and has a margin for the vertical fluctuation width of the float 8, while In addition, as a configuration with a sufficient storage capacity for gas and liquid, the pressure-feeding is continued in a state in which the gas-liquid is completely separated in the sealed container 1.
Usually, a longitudinal length of about 2.5 or more with respect to the inner diameter 1 is effective, but it is not limited.
Further, the inner diameter of the sealed container 1 should be at least three times as large as the inner diameter of the injection tube 2, which is effective for gas-liquid separation because air bubbles are mixed into the liquid feeding tube 4 and liquid is mixed into the air feeding tube 6. However, this is not a limitation.

  Furthermore, the present invention enables a configuration in which a gas-liquid mixed flow (gas-liquid two-phase flow) pumped from a gas-liquid pump is a simple and reliable device without using only pipes and containers, so that the present practicality can be achieved. It is characterized by improving the lack of gas-liquid separation.

  Furthermore, the present invention is characterized by a function that cannot be achieved by a conventional gas-liquid separator, that is, a device in which the water level in the sealed container 1 cannot easily reach the upper end and the lower end.

  Furthermore, the present invention is characterized in that the gas-liquid separation function can be exhibited not only in water but also on the surface of the water or on land, as needed.

  Furthermore, the present invention is characterized in that the gas-liquid separation function is not affected even at shallow water depth or deep water depth.

  Furthermore, the present invention is characterized in that even if the length of the air supply pipe 6 and the length of the liquid supply pipe 4 are changed, the internal water level does not shift to a unilateral place, and the generation of pulsating flow is alleviated.

  Furthermore, the present invention is characterized in that the water level in the gas-liquid separator can be automatically opened and closed regardless of where the gas and liquid are discharged and discharged.

  Furthermore, the present invention is characterized by minimizing the occurrence of failure as a simple configuration as an automatic water level adjusting device.

  The land-and-land flowable gas-liquid separation device of the present invention can easily and reliably perform gas-liquid separation of the gas-liquid mixed flow (gas-liquid two-phase flow) pumped from the gas-liquid pump, and greatly increases the use of the gas-liquid pump.

  Furthermore, the present invention has become a device that can sufficiently exhibit the gas-liquid separation function regardless of the installation location of the gas-liquid separator in the water, the water surface, and the land.

  Furthermore, the present invention is an apparatus that can double the depth of water reached by bubbles by installing the gas-liquid separator in water.

  Furthermore, the present invention enables non-polluting excavation in water using a gas-liquid pump.

  Furthermore, the present invention can enhance the dissolved oxygen in the bottom water without releasing bubbles into the water in combination with the gas-liquid pump.

  There is an effect that the gas-liquid separation function is not hindered by re-mixing and pulsation of the gas-liquid, depending on the length of the air-supply hose and the water-supply hose from the gas-liquid separator and the vertical position of the installation location.

  By separating the gas-liquid mixed flow into gas and liquid, high-pressure gas and high-pressure liquid can be secured without vibration and noise without using a conventional compressor or blower, and the noise and vibration pollution are extremely reduced. .

  The best mode for carrying out the invention of the land-and-land gas-liquid separation apparatus of the present invention is as described in claim 5 and as shown in FIG.

  Further, the reason why the land-and-air universal gas-liquid separator of the present invention is the best mode for use in the present invention is that the liquid opening / closing device 9 and the liquid feeding port 5 of the gas switching device 10 and the opening and closing of the air feeding port 7 are the liquid feeding. Along with the pipe 4 and the air supply pipe 6, it can be automatically changed in size, and a sticking phenomenon can be almost eliminated by adopting a cylindrical shutter, and the liquid supply port 5 and the air supply port 7 are automatically opened and closed together with the float 8. This is because it can be done easily.

  Furthermore, the reason why the land-and-water-free gas-liquid separation device of the present invention is the best mode for use in the present invention is that the gas-liquid separation function is hardly affected regardless of the installation environment and operation.

As shown in FIG. 4, the submersible gas-liquid separator of the present invention can be used both in water and on land, and has a different principle and function from the conventional submerged gas-liquid separator.
The injection port 3 may be installed at any of the upper part, the side, and the lower part of the sealed container 1.
The liquid supply port 5 is preferably provided in the lower part of the sealed container 1 so as to penetrate the sealed container 1 upward.
The installation position of the air supply port 7 is preferably set to communicate with the outside from the upper part in the sealed container 1 through the air supply pipe 6.
The float 8 may be installed independently. However, the vertical movement can be smoothly performed by using the liquid supply pipe 4 and the air supply pipe 6 as a rail along with the liquid supply pipe 4 and the air supply pipe 6.
Although the liquid feeding port 5 is provided in the lower part in the sealed container 1, the liquid feeding pipe 4 may penetrate the sealed container 1 from the lower part to the upper part from the lower part.

  The cross section of the hermetic container 1 of the land-and-land flowable gas-liquid separation device of the present invention is considered to be circular, but is not limited and may be other cross-sectional shapes.

  The end plug 11 of the liquid supply pipe 4 and the end plug 12 of the air supply pipe 6 shown in FIGS. 4, 5, and 6 of the present invention are for the purpose of blocking the force from the pipe end, and eliminate the suction force and the suction force. In order to eliminate the influence of external force on the vertical fluctuation of the float 8, other methods may be used as long as the pipe end can be blocked.

1 and 4 of the present invention are more convenient for land or water surface installation.
FIG. 7 is rather convenient for underwater installation. In this case, a weight may be provided to prevent the gas-liquid separator from floating on the water surface.
When the water bottom is installed, the bubbles can reach a deeper location even at the same pressure as compared to the land and water surface installation, which is effective when excavating bubbles from the water bottom.

  The land-and-land fluid-liquid separation device of the present invention is provided with a gas-liquid pump, thereby producing a synergistic effect and exhibiting a function not found in conventional pumps. For example, all the liquid that has passed through the gas-liquid pump is characterized by high-concentration dissolved oxygen water, so the land-and-sea free gas-liquid separation device converts `` high-concentration dissolved oxygen water without bubbles '' to the sea, lakes, dams, It can be easily drifted to the bottom layer of a pond, etc. to improve the bottom layer water as a means of resolving oxygen deficiency in summer.

  “High-concentration dissolved oxygen water without bubbles” is the most important element for improving the bottom of the water. Currently, the main aeration is the bubble method (water wheel type, underwater air supply method, fine bubble method). `` Dissolved oxygen water '' rises with bubbles and stays in the bottom layer, so there is very little useful water and the effect on power cost is small. Compared with this, the land and water universal gas-liquid separation device of the present invention has `` no bubbles '' Highly-concentrated dissolved oxygen water ”can be discharged to the bottom layer, and it has been confirmed by model experiments that almost 100% of the water is stagnant in the bottom layer and can be useful water. In other words, the conventional bottom layer aeration method can be improved in principle. is there.

  Furthermore, by using the land-and-water free-form gas-liquid separation device and gas-liquid pump of the present invention together, the bottom layer aeration system has all the “dissolved oxygen concentration”, “water volume”, “discharge time”, and “discharge location” determined quantitatively for the aerated water. Display is possible and the improvement plan becomes clear. (In the conventional method, the amount of aerated water could not be determined only by estimation even though the amount of bubbles could be determined.)

  In addition, the land-and-land gas-liquid separation device of the present invention is equipped with a gas-liquid pump and can easily secure pressurized gas without using a blower or compressor, so there are many parts that can enter the conventional aeration field where power costs increase. I'm sure.

  Furthermore, the land-and-water free-form gas-liquid separation device of the present invention is attached to a gas-liquid pump, and after separating the gas, it is used as a bubble pump air supply as an underwater non-polluting excavator for the bottom layer of sea, lakes, dams, ponds Available.

  Further, the land-and-land gas-liquid separation device of the present invention is attached to the gas-liquid pump to separate the gas-liquid and supply the dissolved oxygen water for seafood culture while the gas is used as a bubble pump to fish It can be used to remove feces and can perform two roles in parallel with one pump.

Furthermore, the land-and-air free-flowing gas-liquid separation device of the present invention can be used for securing high-concentration oxygen-dissolved water in hydroponics by being provided with a gas-liquid pump, and can contribute to improving the yield of the cultivation plantation.
These areas have industrial applications that are not found in other pumps.

  Furthermore, the land-and-land gas-liquid separation device of the present invention enters the field of air compression and refrigeration by being attached to the gas-liquid pump.

  In the case of water bottom installation, conventionally, when only air is fed underwater at 1 atm, it can be sent to a depth of about 10 m, but when it is fed by a half-phase two-phase flow, it is sent to almost double the depth. Yes (however, the air flow rate is halved). This phenomenon creates an unprecedented use for improving the bottom environment and drilling the bottom.

  Characteristic expressions of the land-and-land gas-liquid separation device of the present invention are shown only in the main points in [FIG. 1], [FIG. 4], and [FIG. 7], but many other examples are possible but displayed. Absent.
