Abstract

PROBLEM TO BE SOLVED: To develop a technology for a low cost aerobic treatment of sea bottom, since red tide, water bloom and scum are frequently occurring in a closed water area or in a culturing area of seafood in all over the world, and since lower layer water is lack of dissolved oxygen (DO) and a conventional technique has much power waste to surface water and an intermediate water layer, while most of water containing dissolved oxygen generated moves up with air bubbles in water, resulting in inefficiency and high cost.SOLUTION: An apparatus is provided for a direct aerobic treatment of bottom water without generating almost no waste water only by operating air and water and not using conventional pumps, chemicals and industrial products. The technique includes sending air and water in bottom layer water at low temperature from an air and liquid pump for pulling up to an air and liquid separation device to separate highly concentrated water containing dissolved oxygen without air bubbles and discharging again to the bottom layer. Series of works are performed by one power source, and upward waste water is not generated. Almost the total amount of water containing dissolved oxygen with high concentration can be used for the aerobic treatment of the bottom layer. Solar power generation is expected to be used in the technique, and the problem of the lack of oxygen in the bottom layer, which is the cause of red tide, water bloom and scum, is attempted to be solved to contribute to the growth of seafood.

Description

  The present invention uses a gas-liquid pump to solve the shortage of dissolved oxygen (hereinafter referred to as “DO”) in the bottom water of closed water areas, and to enhance and supply DO water in the cultivation of seafood. Water quality is effectively improved with solar power generation to prevent the occurrence of sea urchins, scum and odors, promote the growth of seafood, and reduce CO2 and eliminate the complexity and high cost of power equipment on the water surface. The present invention relates to an apparatus for improving water quality at the bottom and bottom of a water by using a gas-liquid pump.

  Globally, in closed waters such as bays, lakes, dams, large and small ponds, aquariums, etc., red tides, blue sea breams, blue tides, scum and odors are causing environmental damage. The cause is said to be due to the elution of many substances such as nitrogen, phosphorus, iron, manganese, copper, etc. due to anaerobic due to lack of oxygen in the water and bottom of the water, and dangerous gases such as methane gas and hydrogen sulfide are generated. There are a number of aerobic methods that are said to be aerobic in the bottom layer as a countermeasure, but many waste energy and inefficiency due to waste of energy in the surface and middle waters, and there are drastic effects. can not see. In seafood aquaculture, there are waterwheels, underwater air supply type DO supply devices and DO booster devices, which are in the same situation as water quality improvement in closed waters.

  Many methods for improving the water quality of the water and bottom of the water include aeration methods for air bubbles (including microbubbles and other fine bubbles), agitation methods for surface water, fountain methods, chemical injection methods, and fungus mixing and growth methods Although there are methods for dissolving and introducing industrial products such as oxygen, all of them are wasteful and complicated to handle, resulting in inefficiencies and high costs.

  There are conventional methods for dissolving oxygen in the air, that is, aeration is carried out with a compressor or blower, and fine bubbles are released in water. Because it moves up with the upward flow ”, there is very little high-concentration DO water that stays in the bottom layer and is effective in making the bottom layer aerobic. Most fatal defects. It is said that the high-concentration DO water that stays in the bottom layer and is substantially useful for aerobicization is about 10 to 20%. That is, the current technology is that 80 to 90% of the waste water is actually used. This fatal flaw rebounds as a huge equipment cost and power cost, which is the biggest barrier to environmental improvement.

  Furthermore, the surface water agitation method and fountain method using a conventional water wheel have a method that expects convection, but it is effective for enhancing dissolved oxygen in the surface water, but the amount of water reaching the bottom layer is a part of the whole. Although it may be effective for small water volumes of several tons to a hundred tons, such as aquariums and ponds, in normal ponds, lakes, dams, and oceans, high-concentration DO water cannot be expected to circulate to the bottom layer. Most of the dissolved oxygen water is wasted and there is no sign of improvement. The same applies to DO enhancement in seafood farming.

  In addition, the installation of water quality improvement devices in closed water areas often requires power to be placed in the water areas, which is inconvenient and costly for securing power (electric power) in the sea, dams, lakes, and ponds.

  In addition, it is extremely expensive and difficult to draw ordinary power over a wide water surface as a power source for water quality improvement in closed waters. On the other hand, conventional methods are more difficult to introduce solar power generation due to high power costs. Yes, not generalized. From the viewpoint of CO2 reduction, it is nationally advisable if there is a new technology that can use a solar power generation system even if the cost is somewhat high.

Conventionally, the water quality improvement technology for the bottom layer of closed water areas has many problems such as underwater air supply type, agitation type, fountain type, chemical injection type, and low efficiency and high cost. The purpose is to improve the temper, but the reality is inefficiency and high cost on parade. For example, in the underwater air supply type, “DO water rising movement accompanying bubble upflow” and the other is “method for expecting convection”. The latter, which is wasted water, is effective for small quantities of water in the hundreds of tons, but is not applicable to the quantity of water in the sea, dams, lakes, ponds, etc. Blowers, compressors, fine bubbles, waterwheels, fountains In conventional methods such as the formula, DO water generated from the corner rises away from the bottom, so there are too many examples that end up with wasted water and wasted energy, which is not useful for aerobic formation of the bottom layer. Had brought. This is the reason why water quality improvement in closed waters has not progressed.
In addition, the vast water surface facilities for securing the power source are increasing the difficulty and cost. The present invention resides in the development of a technique for solving these problems.

  Furthermore, the present invention eliminates the upward movement of high-concentration DO water, which was the biggest disadvantage of the conventional method, by improving the water quality in closed water areas and supplying DO water in the cultivation of seafood. It is in the development of a device that effectively uses almost 100% of DO water for aerobic formation of the bottom layer.

  Furthermore, the present invention lies in the development of a device that can perform a series of operations with a single power by sucking low-temperature bottom layer water to form high-concentration DO water, and directly flowing out to the bottom layer again. In other words, it is in the development of a technique for directly converting bottom layer water into high-concentration DO water without manipulating surface layer water or intermediate depth water.

  In addition, one of the conventional methods is a method for dissolving industrial products such as oxygen, but this method is not sufficient for generalization because it is difficult to adjust and handle the concentration and there is a danger of danger and it requires specialized knowledge. And is in the development of technology that does not employ the dissolution method of industrial products.

  In addition, the conventional type used power for agitation of surface water and medium-deep water, and power concentration on the bottom water was not observed. It is a technique that is mainly used for bottom water and stays in the bottom and does not waste water to make the bottom aerobic, and is in the development of a new technology that adapts to small and medium ponds, dams, lakes, and the ocean.

  Furthermore, the conventional method is managed in a state where the quantitative grasp is insufficient. The present invention is a management method capable of grasping the quantity, that is, the water supply amount, the dissolution concentration, the discharge depth, the required power, the discharge time. It is in the development of a method to manage in a state that can always be grasped.

Moreover, while there are many examples of use of the conventional solar power generation system, use for improving water quality is hardly visible. Of course, there is no precedent used for a gas-liquid pump.
The technology combining the gas-liquid pump and the photovoltaic power generation system makes it easy to secure the power in the closed water area, and is effective in improving the bottom layer even if the photovoltaic power generation device is small in the closed water area and within the profitable range. It is in the establishment of technology that contributes to the CO2 reduction direction of the entering country.

Furthermore, the development of an apparatus in which the power generation panel is less likely to be contaminated by the damage caused by birds and beasts, feces damage, and flying dust including yellow sand, which has conventionally occurred in the solar power generation system, and the power generation efficiency is not lowered.
Finally, the present invention lies in the development of a technique that allows the work to be performed without noise and vibration compared to the prior art.

  The present invention solves the problems such as the use of the conventional underwater air supply type, water wheel type, fine bubble type, fountain type, industrial product, etc., as well as means for eliminating the difficulty and cost increase of power equipment on the water surface. First, as described in claim 1, the gas-liquid pump 1 is placed in the container 2 and provided near the water surface, and the inlet 3 through which water flows from the outside into the container 2 is provided. The liquid pressure feed pipe 4 is connected to the gas-liquid separator 5, the discharge pipe 6 is connected to the gas-liquid separator 5, and it extends to the underwater / water bottom. The water in the container 2 is pressure-fed to the gas-liquid separator 5 through the gas-liquid pressure feed pipe 4 while gas-liquid mixing is performed. The water level in the container 2 is lowered and external water automatically flows into the container 2 from the inlet 3. Thus, the air and water pumped to the gas-liquid separator 5 are automatically separated to enable the gas-liquid pump 1 to operate continuously. , Air is characterized in that pumping and released from the air moving pipe 9 to the outside only through the discharge pipe 6 water into water or water bottom where it is most needed.

  Further, according to the second aspect of the present invention, a suction pipe 7 (also referred to as an air lift pipe 7) is connected to the inflow port 3 and extends into the water so that the water or the water in the bottom layer automatically flows into the container 2 from the suction port 10. It is characterized by this.

  Furthermore, claim 3 of the present invention is characterized in that a part or the whole of the discharge pipe 6 is laid in a bottom layer or a bottom mud layer, and a large number of discharge holes 8 are provided to discharge the discharge pipe. It is characterized in that the bottom layer is provided as a base of the bottom organism by raising the aerobic property to a wide range of the bottom layer without raising the water, and the purification of the bottom layer water by the bottom organism is promoted.

  Furthermore, claim 4 of the present invention extends the air moving tube 9 to the gas-liquid separator 5 and connects it to the middle of the suction tube 7 so that the air is not released to the outside, and the suction tube 7 (also referred to as an air lift tube 7). The suction pipe 7 is operated as an air lift pump by supplying air in the middle.

  Further, according to claim 5 of the present invention, in order to perform gas-liquid separation reliably and effectively, the water-gas-liquid separation that operates more effectively at a large depth is used instead of the gas-liquid separation device 5 mainly composed of a shallow depth. The apparatus 11 is used.

Furthermore, claim 6 of the present invention is characterized in that the gas-liquid pump is operated by installing the solar power generation device as a power source and the gas-liquid pump 1 as a set.
By combining a gas-liquid pump and a solar power generation system, it is easy to secure power in a closed water area, and by omitting wires, utility poles, cap tires, and box equipment, installation, movement, and removal are easy. Thus, it contributes to CO2 reduction in the global direction.

  According to claim 7 of the present invention, the power generation panel 21 of the solar power generation apparatus is installed horizontally or inclined, and the bird and animal intrusion exclusion apparatus 23 is provided on the upper part. The photovoltaic panel 21 is installed so as to receive light in a direction close to a right angle to the solar light source, and even if some contamination from flying dust including yellow sand adheres, it functions as an automatic cleaning during rainfall. It is intended to prevent power generation efficiency from decreasing, and to prevent damage and fecal damage due to invasion of birds and beasts by installing a bird and animal intrusion prevention device as necessary.

  Finally, the present invention provides a tethering device for continuing operation at a fixed position even in a wide water surface by attaching one or a plurality of tethering devices to the aerobic device for underwater / water bottom by the gas-liquid pump 1. Is provided.

  The present invention is a bottom drift type of only DO water without bubbles, and “the rising movement of DO water accompanying bubble rising flow” is almost eliminated. The spread of the bottom water without bubbles to the bottom layer clearly confirms that there is almost no wasted water even in the experiment, and the effect of DO water on the conventional bottom layer is markedly improved. This makes it possible to use a technique in which nearly 100% high-concentration DO water is useful for aerobic formation of the bottom layer. "And the method of expecting convection" were almost completely wiped out.

  Furthermore, the present invention does not require the use of any industrial product method such as a blower, compressor, water wheel, fine bubble device method, fountain type, oxygen, etc., only air and water operation, no chemicals required, A highly efficient underwater / bottom aerobic operation has been realized with almost no waste.

  Furthermore, the present invention significantly reduces the conventional equipment cost and power cost, and if the conventional type has 80 to 90% of waste, it is considered that the waste is almost zero in the present invention. We can expect effect to make a fraction.

  Furthermore, the present invention can be easily used not only in large closed water areas such as seas, lakes, and dams, but also in small and medium ponds that are in trouble due to aquatic or scum of school, park, shrine, temple, golf course, bad smell. Established technology.

  In addition, the present invention is equipped with a gas-liquid pump and a gas-liquid separation device, and can perform a series of operations that draws low-temperature bottom layer water into high-concentration DO water and directly flows out to the bottom layer again at a low temperature with a single drive. The technology that becomes. Conventionally, two to three power sources were required for this work.

  Furthermore, the present invention does not spend power on the wasteful work, that is, stirring and aeration of the surface layer water and middle layer water, and concentrates energy only for aerobic formation of the bottom layer water, so that almost no waste water is produced. The same effect as before can be achieved with a power of 1 / s of the prior art.

Furthermore, according to the present invention, regarding the quantity display that was difficult or impossible with conventional compressors, blowers, fine bubbles, etc., the management of the quantity became easy by clarifying the quantity grasp.
For example, it became possible to clarify the management of the statement that “the bottom water with a power of 200 watts and a water temperature of 18 ° C. is drifted 50 m ³ every day to the bottom layer with a depth of 2 m with a DO concentration of 9.2 mg / liter”. .

  Further, since the gas-liquid pump 1 is used in the present invention, it is possible to operate without noise and vibration, and it is considered that there is almost no environmental pollution due to noise even in a small and medium pond adjacent to a private house. The same applies to land farming.

  Furthermore, the set of gas-liquid pump and photovoltaic power generation system of the present invention is effective even with small power, so the area size of the photovoltaic power generation panel does not have to be so large, and it is within a reasonable range for installation, movement and removal work. This has contributed to the global reduction of CO2 emissions. Conventionally, it was difficult to secure power in a wide water surface, and the wall was high in cost, but from the high efficiency of the gas-liquid pump type, it has reached the range where it can operate sufficiently even with small power combined with a solar power generation system.

  Furthermore, the present invention effectively increases the power generation efficiency by effectively tilting the power generation panel of the solar power generation system and prevents the power generation efficiency from being lowered by flying dust containing yellow sand. The cleaning function was demonstrated and the power generation function was maintained for a long time. Furthermore, the birds and animals flying prevention device enabled the prevention of dung damage caused by birds and animals.

  Furthermore, the present invention is a device that includes a gas-liquid pump and a photovoltaic power generation system as a set, and can be kept stationary at any required position in a closed water area by floating and tethering the water surface. became.

The figure of the main point of the structure and flow of the underwater / gas-liquid separator 11 of the present invention.

  The best mode for carrying out the invention is as set forth in claim 8 and as shown in FIG. That is, after operating the gas-liquid pump with solar power generation and using the underwater / gas-liquid separation device together, with a single power source, the low temperature bottom layer water is sucked into only high concentration DO water without bubbles, A device that aerobically sends the bottom layer directly to the bottom layer again at a low temperature, and does not release any air bubbles into the water, allowing these operations to be operated without noise and vibration, and preventing birds and animals from flying. Then, the dust including yellow sand is automatically washed by rainfall by tilting the power generation panel. This method is a device that can be used at a water depth of 1.5 meters to 30 meters. By using a gas-liquid pump, solar power generation can be used universally for water quality improvement.

An implementation description of the features and techniques of the present invention is shown below.
The biggest reason why the gas-liquid pump 1 and the gas-liquid separator 5 are used in combination is that it is possible to operate all with one power only by operating air and water without using chemicals or industrial products. The main technical outline is as follows:
(1) All water supply using a gas-liquid pump automatically generates high-concentration DO water.
{Circle around (2)} The low-temperature, low-oxygen water in the bottom layer is automatically pulled from the air lift pipe 7 into the container 2 of the gas-liquid pump 1.
(3) Air and water (high-concentration DO water) are automatically separated by the gas-liquid separator 5 (or the water / gas-liquid separator 11).
{Circle around (4)} Only high-concentration DO water is sent to the bottom layer without releasing bubbles into the water, and is discharged from the numerous discharge holes 8 of the discharge pipe 6.
(5) The separated air is injected from the air moving pipe 9 into the inflow pipe 7 and the inflow pipe 7 is operated as a bubble pump to promote the inflow of the bottom layer water into the container 2.
(6) Operate a series of operations without noise and vibration.
(7) In the present invention, “air” and “water” are described, but they may be understood as “gas” and “liquid”.
(8) In the illustration of the present invention, although power equipment is not shown, it goes without saying that power equipment is necessary for all of them.

Furthermore, the present invention is characterized in that, as a means for solving a fatal defect of the conventional method, a gas-liquid separation device 5 for preventing bubbles from being discharged into water is used in addition to the gas-liquid pump 1. Yes, the gas-liquid separation device 5 enters the gas-liquid separation device 5 in a mixed state of air and water, and then pumps only high-concentration DO water to the discharge pipe 6, so that a number of wells provided in the discharge pipe 6 are provided. From 8 to the bottom of the water (or in the bottom mud). The reason for separating by the gas-liquid separator 5 is that no bubbles are released into the water and that the separated bubbles are used as an air lift for lifting the oxygen-poor water.
The apparatus for separating gas and liquid shown in FIGS. 1, 2 and 3 is a “gas-liquid separator 5” which is an amphibious type, but when the water depth exceeds 1 m, the “underwater” shown in FIGS. -The gas-liquid separator 11 "is convenient. The “gas-liquid separator 5” is preferably installed in the vicinity of the gas-liquid pump 1 and may be in water, on the water surface, or above the water surface, but is not particularly limited as long as it is convenient for operation and maintenance. The “underwater / gas-liquid separator 11” is installed in the bottom layer in the drawing, but may be suspended in water.
The “cylinder / gas-liquid separation device” shown in FIG. 4 is a device having a simple structure and relatively few failures, and has a configuration in which natural air is released into the atmosphere without using separated pressure air.

  In the present invention, air and water are expressed, but air means gas and water means liquid, and it is not necessarily limited to air and water.

Further, in the present invention, the inlet 3 is not described in the drawing or text regarding the clogging prevention device, but this is because the drawing and explanation become complicated, and clogging with sludge and underwater substances depending on the situation. Needless to say, a device for preventing this is provided.
Similarly, although the outlet hole 8 is not shown in the drawing, it goes without saying that a clogging prevention device is provided with sludge and underwater substances when the caliber is large.

  Furthermore, the present invention is characterized in that the conventional uncertain quantity expression can be improved and work management can be performed with a clear quantity expression. In other words, “how much power, how many times the water temperature, how much dissolved concentration, how many m3 of dissolved water is released in what time in what depth of water,” this expression method is in other existing methods It is something that cannot be seen.

  Furthermore, since the present invention uses a gas-liquid pump, a series of operations of gas-liquid mixing, water supply, gas-liquid separation, and springing are achieved with a single power of the gas-liquid pump.

  Furthermore, the present invention is characterized in that it requires no soundproofing equipment or vibration-proofing equipment because it works with no noise and no vibration compared to the prior art.

Furthermore, the main points of the “gas-liquid pump” of the present invention are as follows.
(1) Gas-Liquid Pump 2 was patented on May 11, 2001 and is a new principle pump not found in engineering books. It has been announced at the Japanese Society of Multiphase Flow in 2002, but the standard name is also classified. In the application documents of the present invention whose position has not yet been determined, the name “gas-liquid pump” is unavoidably described, but the name of the gas-liquid pump is a trademark of the inventor and is not a standard name. In other words, it is a pump that operates without noise and vibration at a rotational speed of about 1/100 that of a conventional pump without using any conventional blades, gears, pistons, and screws, and is a pump based on a completely different principle.
(2) A gas-liquid pump has a long hose (or pipe) wound around a ring and is installed near the surface of the water, with one end of the hose serving as an inlet and the other connected to the inside of the rotating shaft. The gas is then connected to an external pressure feed pipe, and gas and liquid are alternately pumped from the inlet through the rotation of the winding body, passing through each winding ring, and then gradually increasing the pressure to maximize the final ring. This is a gas-liquid two-phase flow pump that is pressurized and pumped to the outside.
(It is a pump that does not require any internal equipment such as blades, gears, pistons, screws, etc. required for conventional pumps, and can be hollow from the spout to the spout)
(3) No noise and no vibration due to extremely low speed rotation (2-60 rpm) compared to conventional pumps.
(4) Gas-liquid enters from the pump inlet (pumping inlet), and the pumping pressure gradually increases inside and reaches the highest pressure in the final winding ring. The pumping pressure (lift) increases in proportion to the length of the winding hose. The amount of pumping can be adjusted by adjusting the diameter of the hose. The lift is 25% to 28% of the winding hose extension and is also related to the rotational speed.
Since air and water are sent in a mixed state (gas-liquid two-phase flow), high-concentration DO water is automatically generated during the pumping process. This is one reason why conventional pumps are not used.

The gas-liquid separator 5, the water / gas-liquid separator 11, and the cylinder / gas-liquid separator 30 described in the present invention all have high-concentration DO water that effectively separates gas and liquid and has no bubbles. This is a device that pumps only water into the water and the bottom of the water. .
There are various types of normal gas-liquid separation devices used for gas-liquid pumps, but each type accepts continuous gas-liquid two-phase flow feeding under pressure and immediately separates into gas with pressure and liquid with pressure. The gas-liquid separation device itself does not require a power source. The technical point is how to effectively utilize the pressure gas and the pressure liquid that are generated at the same time after gas-liquid separation. The gas-liquid separator used in the present invention is for a gas-liquid pump, and the type is not particularly limited as long as it fulfills the functions of the previous period. In the present invention, the liquid after gas-liquid separation may be discharged to the bottom layer, and the gas may be used for lifting the bottom layer water by an air lift or released to the atmosphere.

There are three types of apparatus for separating gas and liquid described in the present invention. The first is “gas-liquid separator 5” which is used for amphibious purposes and is convenient to use within a relatively shallow depth of 1 m. The “underwater / gas-liquid separator 11” is effective when used at a deep water depth, that is, when used at 1.5 to 30 m. The third is a “tubular / gas-liquid separation device 30”, which is mainly composed of a cylindrical water tank 31 as shown in FIG. 4, which is configured to connect the gas-liquid pumping pipe 4 from the gas-liquid pump 1 to the cylindrical water tank. The gas-liquid pumped from the gas-liquid pump 1 passes through the gas-liquid pumping tube 4 and enters the cylindrical water tank 31 so that the gas is in the atmosphere. Water (liquid) is stored in the cylindrical water tank 31 and forms a water level H at the same time as it is naturally ventilated, and is naturally passed through the discharge pipe 6 and sent to a necessary place at the pressure of the water level H. Although the shape of the cylindrical water tank 31 is often vertically long, it may be horizontally long and is not limited to vertically long, and since the upper part is not sealed, air (gas) is naturally discharged into the atmosphere. The upper part of the cylindrical water tank 31 is configured to allow air to enter and exit, but as shown in FIG.
That is, the gas-liquid separation device of the present invention includes three types: a gas-liquid separation device 5, an underwater / gas-liquid separation device 11, and a cylindrical / gas-liquid separation device 30. Both have a common function of separating a gas-liquid two-phase flow (a mixed flow of air and water) and discharging water having a high dissolved oxygen concentration (DO concentration) into the water and the bottom layer. These three types of gas-liquid separators should be selected depending on the location, usage method, and water depth, and are not intended to limit the range of use.

  The outflow hole 8 is not to release vigorously just like the outlet of a hose, but to discharge high concentration DO water from the discharge pipe 6 into the outside water from many places. It is better to make the sludge spring without raising it. Although the diameter of the swell hole 8 has a range of 1 to 20 mm, it is not limited. “Provide a large number of spring holes 8” means that a large number of spring holes 8 are provided to weaken the discharge power and diffuse widely in the bottom layer. In this model experiment, we observed an ellipse drifting laterally so as to crawl the bottom layer. In the experiment, the rising phenomenon of discharged DO water was not observed.

  Furthermore, laying a part or the whole of the discharge pipe 6 in the bottom layer or the bottom mud layer and providing a large number of outlet holes 8 makes the bottom mud layer aerobic as well as the bottom layer water. . As the bottom mud layer is aerobic, organic matter in the bottom mud may be decomposed by microorganisms and volume reduction may proceed. The term “swelling” refers to a discharge method in which high-concentration DO water is discharged from the water pipe 6 into the outside water relatively quietly and stagnated near the bottom layer to prevent the surrounding sludge from rising.

An example of a test in which about 2000 tons of pond water was pumped from more than 100 bottom layers with a power of 200 watts, high concentration DO water of about 8.0 mg / l, and 50 tons a day at a depth of about 1.2 meters. It was confirmed that the Aoko and scum surfacing seen until last year has disappeared.
As an example of the conventional bubble discharge type and water wheel type, when improving the bottom layer of about 1,200 tons of pond water generated by blue sea bream, usually 1 kilowatt to 2 kilowatt power is required, this time its 1/5 to 1 ・With 10 powers, we were able to observe the eradication of blue sea bream, scum and odor.

  In claim 1, it is described that “the gas-liquid pump 1 is placed in the container 2 and provided near the water surface”. This is a surface-floating type, a surface-floating tethered type, and a case where it is fixedly installed near the water surface. Which one to decide is determined by the current situation. Claim 1 is convenient when the depth is relatively shallow. In the present invention, all the gas-liquid pumps are shown to be installed in a water surface floating type, but may be installed in either a water surface fixed type or a water surface tethered floating type as required. A water surface fixing type is convenient for water surfaces with small changes in water level.

  The inflow pipe 7 of claims 2 and 3 sends the pressure air from the gas-liquid separator 5 to the inflow pipe 7 through the air supply pipe 9, and operates the inflow pipe 7 as an air lift pump so that the bottom layer water is contained in the container 2. This is convenient when the water depth is 1.5 m or more.

  The water depth used in the present invention ranges from 0.5m to 30m, with a wide range of closed waters such as seas, lakes, dams, and small and medium ponds (ponds for parks, schools, company Buddhist temples, hotels, golf courses, etc.) In the case of a large-scale, which is considered to be, the water depth is theoretically possible even at 30 to 50 m.

Claim 1 is a method in which the inflow pipe 7 is not used, and is a system in which water close to the surface is pumped from the gas-liquid pump 1 to a required place in the water.
The second aspect is a system using the inflow pipe 7 and a system in which the water in the bottom layer is drawn up and sent.
The third aspect is a system in which the high concentration DO water is discharged to a necessary place in the water by providing the discharge hole 8.
According to the fourth aspect, with respect to the pressure air separated by the gas-liquid separator 5, the air moving pipe 9 is extended and connected to the suction pipe 7 (also referred to as an air lift pipe 7) to add an air lift effect to the drawing of the bottom layer water. Is. This air lift brings about aeration effect as well as withdrawing bottom water.
The fifth aspect uses an underwater / gas-liquid separation device 11 instead of the gas-liquid separation device 5, and the air moves to the air lift pipe 7 inside the device to lift the bottom layer water by the air lift effect and bring about an aeration effect. Is.

  Regarding the surface levitation of the container 2, the container 2 containing the gas-liquid pump is a surface levitation type in the drawing, but is not limited to the surface levitation mooring type, the surface levitation fixing type, or the surface levitation type. Good.

  Although the claim 8 is not shown in the figure, it is clarified that the entire gas-liquid pump including the solar power generation device, that is, the aerobic device for the underwater / water bottom is connected to the bottom or the shore by a rope, a wire or a chain. It has shown that it is set as the structure which is tethered from multiple directions and operates in a fixed position.

  When the bottom water is withdrawn from the suction pipe 7 to the container 2, there are cases where the amount of water drawn from the air lift pipe 7 is excessive, and conversely, the amount of water drawn is excessively small. Can be absorbed but cannot be handled by connecting a water amount adjusting pipe from the container 2 (not shown because the drawing is complicated). Further, it is possible to cope with the problem by adjusting the diameter of the air lift pipe 7 to either large or small.

Regarding the gas-liquid separation device 5, although not shown in the air moving tube 9 and the discharge tube 6, pulsation tends to increase, so that there may be a need to adjust the transfer amount to the outside for both gas and liquid. Since the drawing is complicated in detail, the illustration is omitted.
With respect to the underwater / gas-liquid separator 11, the air moving tube 9 is installed inside, and the pressure gas automatically moves to the air lift tube 7 to exert an air lift effect. In this case, the pulsation is small and there is no significant effect on actual operation.

  Neither the gas-liquid separator 5 nor the underwater / gas-liquid separator 11 is used, but the cylinder-type gas-liquid separator 30 is used. In this case, of the gas-liquid pumped from the gas-liquid pump, Air is automatically diffused from above into the atmosphere, so it cannot be used for airlifts. However, there are few failures and the pumping status can be easily grasped, and even if a failure occurs, it is easy to deal with, and it is effective for securing only DO water. Method.

  At low water depths, even if an airlift is used, the rising force of bubbles is small, so the amount of pumped water may be reduced and the amount of water in the container 2 may be insufficient. In this case, although not shown, is the diameter of the airlift pipe 7 increased? Or, an excess / deficiency adjustment pipe may be attached.

  Although it is made sideways with respect to the well 8, it is not limited and may be sideways, diagonally sideways, or downside. Any direction may be used as long as it is effective for aerobic bottom water and mud.

  Although the suction port 10 of the inflow pipe 7 (air lift pipe 11) is not shown, it is usually necessary to cover it with a net or the like in order to avoid suction of sludge and impurities.

  The inflow pipe 7 (air lift pipe 11) and the gas-liquid pressure feed pipe 4 need to cope with fluctuations in the water level including the tide level, and may be configured to be able to expand and contract in the middle as needed. Although not shown, any material of a hose or a pipe can be used.

  The high-concentration DO water produced by the gas-liquid pump 1 normally approaches the saturated concentration when the total length of the winding hose of the gas-liquid pump 1 exceeds 20 m. If the extension of the winding hose is 20 m or more, the DO concentration exceeds the saturation concentration, but it is not economical.

  The volume ratio of the pumped gas / liquid from the gas / liquid pump 1 is usually 60% for gas and 40% for liquid. The reason is that this ratio is convenient in construction and the volume of gas is reduced by increasing pressure, but there is no liquid. For this reason, it is effective to increase the amount of gas in advance. In the present invention, the volume ratio is not limited.

  As described in Patent Documents 7 to 9, the “gas-liquid separation device” used in the present invention needs to employ a gas-liquid pump, and the amount of gas and liquid pumped by the upper and lower floats in the gas-liquid separation device 5 The internal water level is automatically controlled, and the float in operation is configured to maintain an intermediate position while always going up and down.

  Regarding the “gas-liquid separation device” described in Patent Documents 7 to 9, there is a function of automatically adjusting the gas and liquid pumping amounts of gas and liquid to separate the gas and liquid, but the current situation is insufficient. The “gas-liquid separation device 5” used in the present invention, which has the disadvantage that gas is mixed into the liquid, is safe to use the improved type in which the pressure-feed amount can be surely automatically controlled. Since the detailed description of the “liquid separator” is different from the description of the present invention, the detailed configuration diagram is omitted.

  In the present invention, FIG. 6 uses solar power generation as a power source, but other than FIG. 6 uses power sources other than solar power generation although not shown.

  In addition to Patent Documents 7 to 9, many have been developed as “gas-liquid separators”, but it is not clear whether they are suitable for gas-liquid pumps. In the present invention, the improved type of Patent Documents 7 to 9 is used. Although it is safe, other developed products may be used if the gas-liquid separation function is reliable.

  The gas-liquid pump operates with low power and is relatively effective in making the bottom layer aerobic. For example, it is possible to make the bottom layer of 2,000 tons of pond water aerobic by securing 200 watts with a power generation panel of about 3 m2. Proven, this is a fraction of the conventional power. This indicates that the versatility of the solar power generation apparatus is approaching.

  The ultrafine wire for excluding birds and beasts is preferably an extremely thin rust-resistant steel wire that does not reduce the efficiency of the photovoltaic power generation panel 21, but the steel wire is not necessarily required. A very thin thing that is difficult to stop birds and beasts is good.

  In the drawings of the present invention, FIGS. 1 to 5 show a float 12, which is attached when a gas-liquid pump is installed in a surface-floating type. Floats are not required when installed in

  The best mode for carrying out the present invention is as shown in FIG. 6 as described in claim 8, but claims 1 to 5 can be used with ordinary electric power and are submerged and submerged by a gas-liquid pump. Aerobicization device, which does not agitate or aerate the surface water and middle layer water, that is, to make the bottom layer aerobic, the bottom layer is hardly used with extra energy such as aeration of surface water and agitation of middle layer water. It is a device that aerated only water.

The “aerobic device for underwater / bottom bottom using a gas-liquid pump” of the present invention is troubled by the occurrence of red tides, blue sea bream, scum levitation, and bad odor due to the global pollution of closed waters, especially bottom water anaerobic. There are too many locations, and the possibilities for use in improving the bottom environment of these large and small water areas are endless. Both technologies currently use a lot of wasted energy for surface water and middle water, and power and equipment costs are enormous, so it is extremely expensive and difficult to secure power in closed water areas. Even with small power, the effect is large and there is little waste, so the use of solar power generation is within the reach, and in some cases it may be cheaper than conventional power equipment, and the expectation of future usability is high from the CO2 reduction effect .
Although the present invention has been described mainly in the closed water field, DO enhancement in the cultivation of seafood is also used as an aerobic device for underwater and water bottom.
