ない。In recent years, it has been pointed out that global warming is caused by the greenhouse effect caused by the increase in carbon dioxide in the atmosphere, and there is a need for power generation systems with higher fuel efficiency from the viewpoints of reducing carbon dioxide emissions and saving energy. For example, the amount of carbon dioxide generated by gas turbine power generation using LNG (liquefied natural gas) as fuel is approximately noisier than oil-fired power generation with the same amount of power generation, which significantly reduces carbon dioxide emissions into the atmosphere. can. However, gas turbine power generation has poor power generation efficiency. This is because the generator and compressor are driven at the same time to create high-pressure air, and this air is used to burn fuel and generate electricity. The power required for the compressor amounts to 10% of the turbine output. Therefore, a compressed air utilization system was devised to increase the power generation efficiency of gas turbine power generation. This system uses so-called late-night electricity to drive a compressor during times when electricity demand is low, stores high-pressure air in a pressure storage tank, and uses that high-pressure air for gas turbine power generation during times when demand is high. . According to this system, there is no need to drive a compressor, and all the electric power generated by the gas turbine can be supplied to customers. The late-night electricity used to compress the air is highly dependent on base-load nuclear power generation, so there is no increase in carbon dioxide emissions. The pressure of compressed air used in normal gas turbine power generation is 10
~40 kg/cm2, requiring a pressure vessel for storage. At present, several hundred thousand kilowatt-scale power plants using compressed air are being constructed, but all of them have air pressure storage tanks installed on land. If a pressure storage tank is installed at the bottom of the water, it becomes possible to design a container that utilizes water pressure, so the underwater air pressure storage tank shown in Figures 4 and 5 was planned. However, these underwater air pressure storage tanks have many unresolved problems such as tank structure, assembly method, installation method, and safety. The underwater air pressure storage tank 30 shown in FIG. 4 is a rectangular parallelepiped hollow container with a large capacity (approximately 50,000 to 10,000 g). The second part is provided with an air pipe 31 that connects to a land-based air supply and exhaust system, and the lower part is provided with an inlet and outlet port 32 through which water enters and exits. However, this device 30 has several structural, practical, and safety problems. In terms of structure, the underwater air pressure storage tank 30 generates a large buoyant force when filled with air, so it requires a considerable weight to be fixed to the bottom of the water. Such huge heavy objects are difficult to manufacture on land, and difficult to transport and install. Furthermore, in order to ensure the airtightness of the container itself, it is necessary to protect the inner wall with an iron plate or a water-resistant resin coating. In practical terms, since air 8 and water 9 are in contact inside the device, water 9 may mix with the air 8 taken out to land, causing the so-called champagne phenomenon, which may damage or corrode the turbine, etc. . In terms of safety, containers placed at the bottom of the water3
If the vessel is destroyed, the air 8 released at -degrees will expand to several tens of times its volume on the water surface, generating large waves and potentially capsizing the vessel. The underwater air pressure storage tank 40 shown in FIG. 5 is a combination of a plurality of pressure storage tanks 45 in which an air chamber 43 and a ballast chamber 44 are integrated. This underwater air pressure storage tank 40 is manufactured by connecting a plurality of pressure storage tanks 45 separately manufactured on land. Air chamber 43
The ballast chamber 44 and the ballast chamber 44 are filled with air and then towed to the installation site, water is injected into the air chamber 43 and the ballast chamber 44, and the ballast chamber 44 is sunk to the bottom of the water. Although this installation work is easier than that of the underwater air pressure storage tank 30 shown in Figure 4, it is difficult to ensure the airtightness of the container itself, and because the air 8 and water 9 are not separated, water is caused by the champagne phenomenon. The speech bubble is not resolved.

である。When the air sending and receiving device 6 on land is operated and air 8 is sent to the air bag 3 through the air pipe 5 and the opening/closing valve 4, the air bag 3 expands while discharging water 9 in the container 2 to the outside through the small hole 7. Compressed air 8 having approximately the same pressure as water is stored in the air bag 3 . When using the compressed air 8, the compressed air 8 is returned to land through the air pipe 5. When the air 8 in the air bag 3 decreases, water 9 enters the container 2 through the small hole 7, causing the air bag 3 to contract.
. Therefore, on land, compressed air 8 that is approximately equal to the water pressure is always obtained. By storing compressed air in the air bag 3 using electricity at night when electricity demand is low, and then taking it out during the day when electricity demand is high and using it for gas turbine power generation, there is no need to drive a compressor that consumes a large amount of electricity. Furthermore, even if the air bag 3 ruptures, most of the air remains inside the container 2 and is gradually released from the small hole 7, so that a large amount of air does not rise all at once and reaches the water surface. Capsizing accidents of ships due to the occurrence of large waves can be avoided. [Examples] Examples of the present invention will be described in detail below. Fig. 1 is a partial cross-sectional side view of the underwater air pressure storage tank of the present invention, and Fig. 2 is a side view of the submersible air pressure tank of the present invention. The front view and FIG. 3 are explanatory diagrams showing the installed state.The underwater air pressure storage tank of the present invention has a plurality of air pressure storage tanks 1, 11, 12, . . . as shown in FIGS. 1 and 2.・is connected by a support member 12.Air pressure storage tank 1・], I
12... is a cylindrical container 2 in which an air bag 3 formed in a cylindrical shape is provided. The air bag 3 is airtightly connected to the compressor and combustion chamber of the gas turbine power plant 6 via the air pipe 5 of the air bag 4 (see Fig. 3).The end of the air bag 3 is fixed to one end of the container 2. In container 2
It is inscribed in the body and can be expanded and contracted in the longitudinal direction by the inflow and outflow of air. The other end of the container 2 is provided with a plurality of small holes 7 through which water 9 can enter and exit. A lubricating layer 11 made of synthetic resin is pasted on the inner peripheral surface of the container 2 . Container 2 is made of concrete. Since the structure allows water to enter and exit through the small holes 7, it is not necessary to ensure airtightness or pressure resistance, but a certain amount of weight is required to suppress buoyancy when the air bag 3 is filled with air. The air bag 3 is made of synthetic resin nonwoven fabric or rubber that can expand and contract according to pressure accumulation and exhaust. Large pressure resistance is not required to keep the stored air pressure and water pressure in equilibrium. The air bag 3 and the air supply pipe 5 are connected via an on-off valve 4, and the air supply pipe is used to connect the plurality of air pressure storage tanks 1, 1, . 5 uses a flexible and high-strength material. This underwater air pressure storage tank is installed as follows. The air bags 3 of the air pressure storage tanks 1-11, 1□, etc. manufactured separately are filled with air, the on-off valves 4 are closed, the tanks are floated on the water surface, and the tanks are towed by a ship 15 to the installation site as shown in Fig. 3. Each air pressure storage tank 1, 11, 12, etc. is of a size that can be easily towed by a ship 15. Float each air pressure storage tank 1-11, 1□, ... on the water surface at the installation location. , each air pressure storage tank 1
・1.・1□... are connected and assembled using the support member 12. Stacking can be done on a small scale with only 16 lanes. Predetermined number of air pressure storage tanks 1.1. -12...- is completed, an air supply pipe 5 (shown by a chain line) is connected to each opening/closing valve 4, and the air 8 in the air bag 3 is discharged. Then, the air bag 3 contracts and water 9 flows into the container 2 from the small hole 7.
is infiltrated. When the inside of the container 2 is filled with water 9, the underwater air pressure storage tank loses its buoyancy and gradually sinks into the water, and is fixed to the bottom of the water. As described above, the underwater air pressure accumulator of the present invention is easy to manufacture and transport, and can be assembled on water using buoyancy. The load capacity of the crane 16 is also small. This underwater air pressure storage tank works as follows. The compressor is driven using electricity at night when electricity consumption is low, and air is sent to the air bag 3 through the air pipe 5. When the air pressure in the air bag 3 becomes higher than the water pressure, the air bag 3 expands as shown by the chain line, and the water 9 in the container 2 is discharged from the small hole 7.The air bag 3 fills up the volume of the container 2. When it expands and the air pressure starts to rise, stop the air supply from the compressor.You can set it to automatically stop the air supply when the air pressure becomes 1 kgf/cm2 higher than the water pressure. During the day, the electricity used to drive the compressor relies heavily on nuclear power generation, which is the base load, so carbon dioxide emissions from burning fossil fuels are suppressed.During the daytime, when electricity demand is high, pressurized air8 It is returned to land through the air pipe 5 and used for gas turbine power generation.The air bag 3 contracts as the air 8 is used, but water can freely enter and exit from the small hole 7 inside the cylindrical container 2. Therefore, the same air pressure as water pressure can always be obtained on land.''As described in 1., the underwater air pressure tank of the present invention stores electric power during periods of low electric power demand as compressed air, and uses the compressed air to meet the electric power demand. Therefore, there is no need to drive a compressor during gas turbine power generation, and all the generated power is supplied to customers, greatly contributing to energy savings. In addition, since the compressed air 8 taken out is separated from water by the air bag 3, there is no moisture content or water blowing out due to the champagne phenomenon, and the turbine etc. will not be corroded. Since it has a structure in which a plurality of independent air pressure storage tanks 1-1., 1□... are connected by a support member 12, the space between each air pressure storage tank 1-1., 1゜... can be reefed. In addition, although the cylindrical container 2 and the air bag 3 are used in the above-mentioned embodiment, their shapes can be arbitrary. [Effects of the Invention] The above-described in detail As such, the underwater air pressure storage tank of the present invention is a combination of a plurality of air pressure storage tanks, and is easy to manufacture, transport, and install.Since the compressed air is stored in the air bag, airtightness is easily maintained. Since air and water are not in direct contact, only dry air can be taken out.Even if the air bag ruptures, the air is gradually exhausted, making it highly safe.In addition, the underwater air of the present invention According to the pressure accumulator installation method, it is possible to assemble the underwater air pressure accumulator on the water and easily install it.
