Description

Carbon-free energy production, storage, and consumption devices

[0001] The present invention relates to a device capable of producing, storing, and consuming carbon-free energy, and more specifically, to a carbon-free energy production, storage, and consumption device capable of producing compressed air using hydraulic pressure and buoyancy and enabling storage and consumption to occur simultaneously, thereby enabling diverse and effective use of compressed air.

[0002] Electricity is generally not created by itself, but is created by other energy sources and can be easily converted into other energies. This characteristic makes it convenient to use.

[0003] However, electricity has the disadvantage of not being stored, so it must be used as soon as it is produced, and if it is not used up in time, it disappears.

[0004] In addition, electricity is produced using turbines in all power generation except for solar power generation, and the core technology is to rotate the turbine at a constant speed. Electricity is not produced directly by nuclear power, oil, or coal, but is produced by a constant force that rotates the turbine. Therefore, electricity can be produced as much as there is a constant force that rotates the turbine.

[0005] And since most of the devices and equipment currently used in production and consumption facilities are powered by electricity, the supply of electricity can be said to be a key element in the operation of production and consumption facilities.

[0006] Meanwhile, when the supply of electricity is achieved through thermal power generation, a large amount of fossil fuels, such as coal, oil, and natural gas, are consumed, which not only exacerbates resource shortages but also causes environmental pollution due to the generation of combustion gases and dust.

[0007] And when electricity is supplied through hydroelectric power generation, resources such as fossil fuels can be protected, but because a large dam must be built in a specific area with a large head difference, not only is there environmental destruction during the construction process, but the ecosystem is also damaged, and there is the problem of difficulty in generating electricity during dry and freezing seasons, and since power generation is only generated during the process of releasing water from the dam, the kinetic energy of the water cannot be utilized in the sections before and after the dam, so there was a problem that the utilization of the kinetic energy of the water was low.

[0008] In addition, even when electricity is supplied through nuclear power generation, resources such as fossil fuels can be protected, but there is a problem of environmental pollution caused by the generation of nuclear waste and radioactive materials during the power generation process.

[0009] And electricity can be generated for power supply using natural energy such as solar power, wind power, tidal power, tidal current power, and wave power. However, wind power generation can produce electricity stably because it utilizes the kinetic energy of the wind relatively sufficiently by changing the angle of the blades and using a gear box, whereas tidal power generation, tidal current power generation, and wave power generation utilize an infinite resource, that is, the kinetic energy of water caused by natural phenomena. However, power generation is only generated when water passes through a seawall, etc., so the kinetic energy of water cannot be utilized in the sections before and after the seawall, and there was a problem that the utilization of the kinetic energy of water was low.

[0010] In addition, since conventional thermal power generation, hydroelectric power generation, nuclear power generation, tidal power generation, tidal current power generation, and wave power generation are ultra-large facilities, there was a problem that it was difficult to utilize them as self-generation means for small facilities such as general building structures.

[0011] For this reason, the field is attempting to develop new energy sources that can prevent the consumption of resources such as fossil fuels, prevent environmental pollution and damage to the ecosystem, increase the efficiency of electricity production, and even be used as a means of self-generation in small facilities, such as technology that utilizes the energy of compressed air as disclosed in Korean Patent Publication No. 10-1295082, but has not yet achieved satisfactory results.

[0012] [Prior Art Literature]

[0013] Republic of Korea Patent No. 10-1295082 (announced on August 9, 2013)

[0014] The present invention has been devised to solve the above-described problems.

[0015] The purpose is to provide a carbon-free energy production, storage, and consumption device in which compressed air produced from various sources of energy, such as renewable energy, thermal power, and surplus electricity, is stored in an open-bottomed underwater tank installed underwater and a ground-based storage tank, and the compressed air stored in the underwater tank and storage tank can be used for cooling or heating or to produce and consume electricity through a generator.

[0021] A storage tank in which compressed air discharged and moved through the above-mentioned transfer pipe is stored,

[0022] A cooling device connected to one side of the above storage tank and cooling the compressed air discharged from the above storage tank to convert it into low-temperature compressed air;

[0023] A heating device connected to the other end of the storage tank, which heats the compressed air discharged from the storage tank and converts it into high-temperature compressed air;

[0024] An electric power generation device that is connected to the above heating device and generates electricity by driving a generator using compressed air discharged from the above heating device; and

[0025] It is installed on the underwater floor and is configured to include a fixing member that is connected to the underwater tank and prevents the underwater tank from floating.

[0026] More preferably, the above-mentioned intake pipe can be supplied with compressed air generated through an air compressor using at least one of renewable energy thermal power, oil gas, nuclear power or surplus electricity.

[0027] More preferably, the intake pipe is configured in multiples, and each compressed air produced in a different manner can be supplied through the other end of each of the intake pipes.

[0028] More preferably, the other end of the intake pipe is connected to an air collector, and compressed air produced in different ways can be supplied to the air collector.

[0029] More preferably, the intake pipe and the transfer pipe may be provided with a check valve, and the storage tank may be provided with a pressure regulating pipe and a pressure gauge.

[0030] More preferably, the storage tank comprises at least one, which may be installed on land near the underwater tank or away from the permanent underwater tank, depending on the site conditions.

[0031] More preferably, the cooling device may be configured to be connected to a general building and to supply low-temperature compressed air to the general building to provide cooling.

[0032] More preferably, the cooling device is connected to a data storage center and supplies low-temperature compressed air to the data storage center to cool the equipment, and waste heat generated when the equipment of the data storage center is cooled can be configured to be supplied to the heating device.

[0033] More preferably, the heating device may be connected to a general building to supply high-temperature compressed air to the general building to provide heating, or may be connected to a compressed air utilization facility to supply compressed air necessary for the operation of the compressed air utilization facility.

[0034] More preferably, the fixed member can be connected to the bottom of the underwater tank through at least one connecting member whose length is adjustable.

[0035] More preferably, an anti-buoyancy means may be provided on the upper surface of the above-mentioned underwater tank.

[0036] More preferably, the buoyancy prevention means is composed of metal or stone and can be configured to be installed on the upper surface of the underwater tank.

[0037] More preferably, the electricity generated in the above power generation device can be configured to be stored in a storage facility.

[0038] The carbon-free energy production, storage and consumption device according to the present invention has the following effects.

[0039] That is, the present invention provides a method in which compressed air flowing into an underwater tank is supplied into the water inside the underwater tank, so that the compressed air is only affected by the water pressure due to the water depth at the bottom of the underwater tank, and thus even low-pressure compressed air can be easily transferred to a storage tank with little energy. Since the compressed air is created by passing through the water at the bottom of the underwater tank, it has the effect of cleanly removing foreign substances without a separate filter. It also has the effect of cooling the heat generated when compressing the air without using a separate cooler. Since the water at the bottom of the underwater tank is introduced and discharged as the compressed air is supplied and discharged, it has the effect of appropriately maintaining the compressed air pressure inside the underwater tank. Since the underwater tank is not sealed but has an open bottom, there is no risk of explosion, and since even low-pressure compressed air can be easily introduced into the underwater tank, there is no need to use a compressor to create high-pressure compressed air, and compressed air generated incidentally at thermal power plants or other facilities can be simply transferred to the underwater tank. This allows for the reuse of compressed air that would otherwise be discarded at various facilities.

[0040] In addition, compressed air supplied to the bottom of the underwater tank can be moved to the above-ground tank through a transfer pipe and then used for cooling or heating through heat exchange, and can also be used to drive a generator to produce electricity or store electricity in a storage facility, so that compressed air can be produced, stored, and consumed simultaneously.

[0041] In addition, compressed air stored in underwater tanks and storage tanks is stored at a pressure greater than atmospheric pressure due to the influence of water pressure and water temperature, and can be easily moved at high pressure by heating and moving the compressed air in the storage tank when sending it to a heating device and generator.

[0042] Meanwhile, since the effects of the present invention described in this manner are naturally exerted by the composition of the described contents regardless of whether the inventor is aware of them, the above-described effects are only a few effects according to the described contents and should not be recognized as describing all effects recognized or actually existing by the inventor.

[0043] In addition, the effects of the present invention should be additionally understood by the entire description of the specification, and even if not explicitly described in sentences, if a person with ordinary knowledge in the technical field to which the described content belongs can recognize such effects through this specification, then it should be regarded as an effect described in this specification.

[0045] FIG. 2 is a perspective view showing the configuration of a submersible tank and a storage tank for producing and storing compressed air according to one embodiment of the present invention.

[0047] FIG. 4 is a schematic diagram showing the configuration of production, storage, and consumption of compressed air according to one embodiment of the present invention.

[0048] FIG. 5 is a schematic diagram showing the configuration of production, storage, and consumption of compressed air according to another embodiment of the present invention.

[0049] The configuration and operation of a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0050] This is intended to explain in detail to a degree that a person having ordinary knowledge in the technical field to which the present invention pertains can easily practice the contents of the present invention, and does not mean that the technical idea and scope of the present invention are limited thereby.

[0051] In addition, when adding reference signs to components of each drawing, it should be noted that identical components are indicated with the same signs as much as possible even if they are shown in different drawings, and terms specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator, and the definitions of these terms should be determined based on the contents throughout this specification.

[0052] Before explaining the specific configuration, let's look at the relationship between electricity and compressed air. Electricity and compressed air can be converted to each other using a simple mechanical device, and energy can be used without much inconvenience if either one is present. Compressed air can be produced using electricity, and electricity can be produced using compressed air.

[0053] However, since electricity can only be produced by rotating a turbine at a constant speed, it is very difficult to produce the two separately, but compressed air can be produced even by operating an air compressor intermittently and irregularly.

[0054] Additionally, by injecting compressed air into water and utilizing water pressure and buoyancy, it is possible to produce and store compressed air in large quantities at once, depending on the method, making it much simpler and easier to produce compressed air than to produce electricity.

[0055] Therefore, the logical and correct way to produce energy is to first produce and store compressed air, and then convert the stored compressed air into electricity to meet energy demand.

[0056] Accordingly, the present invention provides a carbon-free energy production, storage, and consumption device capable of producing, storing, and consuming compressed air, and the configuration of this carbon-free energy production, storage, and consumption device can be broadly divided into an underwater tank installed underwater with an open bottom, an intake pipe supplying compressed air from the outside into the underwater tank, a storage tank in which compressed air is stored through the underwater tank and a transfer pipe, a cooling device that cools the compressed air moved from the storage tank, a heating device that heats the compressed air moved from the storage tank, an electricity production device that drives a generator with the compressed air moved from the heating device to produce electricity, and a fixing member that prevents the underwater tank from floating above the water surface, and the following is a detailed description thereof with reference to the drawings exemplified below.

[0057] First, the underwater tank (100) is

[0058] As illustrated in Fig. 1, it can be installed underwater and compressed air can be created inside.

[0059] The underwater tank (100) can be installed underwater, such as in a lake, river, or sea, and can be installed so that the upper side of the underwater tank (100) is exposed above the surface of the water.

[0060] The underwater tank (100) can be configured in various shapes, such as a rectangular solid or a cylindrical shape, and water can flow in and out of the interior of the underwater tank (100) through the open bottom.

[0061] This underwater tank (100) can be fixed underwater through a fixing member (600) described later, and the fixing member (600) will be described in detail later.

[0062] And the intake pipe (110) is,

[0063] As a means for supplying compressed air into the interior of an underwater tank (100) as shown in FIG. 1, one end is positioned inside through the open bottom of the underwater tank (100), but is positioned in the water filling the underwater tank (100), and the other end is positioned outside the underwater tank (100), so that compressed air is introduced through the other end of the intake pipe (110), and the introduced compressed air is compressed by water pressure while being discharged from the water inside the underwater tank (100) and moves upward by the force of its own buoyancy, and is stored in the underwater tank (100) and the storage tank (200), and when the stored compressed air increases, the pressure increases and the water surface inside the underwater tank (100) moves downward.

[0064] Meanwhile, a pressure regulating pipe (240) capable of regulating pressure and a pressure gauge (250) showing the pressure inside the underwater tank (100) and the storage tank (200) are provided on the upper side of the storage tank (200), so that when compressed air is continuously supplied to the inside of the underwater tank (100) and the storage tank (200) and the pressure rises more than necessary, the pressure gauge (250) is checked and some of the compressed air is discharged through the pressure regulating pipe (240) to appropriately maintain the internal pressure of the underwater tank (100) and the storage tank (200).

[0065] In addition, a check valve is installed in the intake pipe (110) to prevent the compressed air moved into the water tank (100) from flowing back.

[0066] In the case of compressed air flowing in through the other end of the intake pipe (110), for example, renewable energy, wind power, water power, tidal power, thermal power, oil gas, nuclear power, or surplus electricity, etc. can be converted into low-pressure or high-pressure compressed air using an air compressor and configured to flow into the intake pipe (110).

[0067] At this time, as illustrated in Fig. 2, each of renewable energy, wind power, water power, tidal power, thermal power, oil gas, nuclear power, or surplus electricity is converted into low-pressure to high-pressure compressed air using an air compressor, and each of the compressed air can be moved to an underwater tank (100) through each of the plurality of intake pipes (110).

[0068] In addition, as illustrated in FIG. 3, renewable energy, wind power, water power, tidal power, thermal power, oil gas, nuclear power, or surplus electricity, etc., can be converted into low-pressure to high-pressure compressed air using an air compressor, and then transferred to an air collector (160) and then moved to an underwater tank (100) through an intake pipe (110) connected to the air collector (160).

[0069] The conveyance pipe (120) is

[0070] As shown in Fig. 1, compressed air supplied to the bottom of the underwater tank (100) is compressed by water pressure and rises upward by buoyancy, naturally spreading to the storage tank (200) and the underwater tank (100) and stored at the same pressure.

[0071] The storage tank (200) is

[0072] The compressed air supplied to the underwater tank (100) is diffused to the storage tank (200) through the transfer pipe (120) according to the Pascal principle, so that the underwater tank (100) and the storage tank (200) are stored at the same pressure.

[0073] The compressed air stored in this storage tank (200) can be consumed for various purposes by changing its temperature through a cooling device (300) or heating device (400) described later.

[0074] Connected to the underwater tank (100), the underwater tank (100) and the storage tank (200) can be configured as one or more as needed, and can be installed on the water or on land, taking into consideration the installation environment or conditions.

[0075] The storage tank (200) is provided with a pressure regulating pipe (240) capable of regulating pressure on the upper side and a pressure gauge (250) that shows the pressure inside the storage tank (200). Therefore, when compressed air is continuously stored inside the storage tank (200) and the pressure rises more than necessary, some of the compressed air can be discharged through the pressure regulating pipe (240) to appropriately maintain the internal pressure of the water tank (200) and the storage tank (200).

[0076] The cooling device (300) is

[0077] As shown in Fig. 4, it is connected to one side of the aforementioned storage tank (200) and serves to convert the compressed air supplied from the storage tank (200) into the required low-temperature compressed air, and the low-temperature compressed air can be sent to a required space or device.

[0078] That is, the compressed air supplied from the storage tank (200) can be cooled through a cooling device (300), and the cooling device (300) can be cooled through, for example, an air-cooling type in which a heat dissipation cooling fan is attached to a pipe through which the compressed air moves and cools it through the blowing of the fan, or a water-cooling type in which a cooling water pipe is installed inside a container through which the compressed air passes and the cooling water is circulated to cool the compressed air, or it can be cooled through a thermoelectric element utilizing the Peltier effect of a semiconductor.

[0079] The compressed air that has been cooled to a low temperature through the cooling device (300) can be supplied for cooling purposes to general buildings (700) such as apartment complexes or buildings, or special buildings used for special purposes.

[0080] In addition, as shown in Fig. 5, low-temperature compressed air can be effectively utilized by supplying low-temperature compressed air to places where cooling of equipment is absolutely necessary, such as a data storage center (800), rather than simply for the purpose of cooling.

[0081] In addition, in places such as data storage centers (800), waste heat may be generated during the cooling process of equipment, so if this waste heat is sent to a heating device (400) connected to the other end of the storage tank (200), compressed air can be recycled more effectively.

[0082] The heating device (400) is

[0083] As shown in FIGS. 4 and 5, it is connected to the other side of the aforementioned storage tank (200) and serves to convert the compressed air supplied from the storage tank (200) into the required high-temperature compressed air, and the high-temperature compressed air can be sent to a required space or device.

[0084] That is, the compressed air supplied from the storage tank (200) is heated through a heating device (400), and this heating device (400) can be a device that heats the compressed air using hot water, steam, electric heat, etc. as a heat source, and can be configured in the form of a heat pump that uses any one of electric power, solar power, and hot water, for example.

[0085] Additionally, it can be heated through a thermoelectric element utilizing the Peltier effect of a semiconductor.

[0086] Compressed air heated to a constant temperature through a heating device (400) can be supplied for heating purposes to general buildings (700) such as apartment buildings or buildings requiring heating or special buildings used for special purposes through a conveying pipe, and thus can be used as a zero-energy building.

[0087]

[0088] *In addition, the compressed air, which is heated to a certain temperature through a heating device (400) and has its pressure increased, can be supplied to the same compressed air utilization facility (900), such as an amusement facility requiring compressed air, an automobile parts and vehicle manufacturing repair facility, and various manufacturing equipment companies.

[0089] The power generation device (500) is

[0090] As shown in FIGS. 4 and 5, it is a device that is connected to the aforementioned heating device (400), and generates electricity by rotating a turbine with compressed air that has been brought to a high pressure state by heating compressed air supplied from a storage tank (200), thereby driving a generator through a gearbox.

[0091] Electricity generated through such an electric power generation device (500) can be supplied to facilities and devices requiring electricity, and can also be stored in a storage facility.

[0092] The fixed member (600) is

[0093] When compressed air flowing in through the intake pipe (110) passes through the water of the underwater tank (100) and gathers on the upper side of the interior of the underwater tank (100), buoyancy is generated, and this buoyancy serves to prevent the underwater tank (100) from floating.

[0094] The fixed member (600) may be a structure installed on the underwater floor as shown in FIG. 1, and the fixed member (600) may be directly connected to the bottom of the underwater tank (100) or may be connected through a connecting member, and the connecting member may be configured as a structure that connects two facing parts of the underwater tank (100) to the fixed member (600), or a structure that connects four facing parts of the underwater tank (100) to the fixed member (600), for example.

[0095] In addition, the connecting member can be configured in a form in which the length is adjusted in multiple stages, which allows the installation position of the underwater tank (100) to be appropriately adjusted according to the varying water level when the water level is variable, thereby improving the installation efficiency of the underwater tank (100).

[0096] The length-adjustable connecting member may be, for example, a bisected member that is fixed at an appropriate position by a fixing means while being raised and lowered along the longitudinal direction of the other member, so that the overall length can be varied to various lengths. One of the bisected members may be provided with a rail groove, and the other member may be provided with a rail portion that is installed in the rail groove and is raised and lowered along the rail groove.

[0097] Meanwhile, when the buoyancy inside the underwater tank (100) reaches its maximum while the underwater tank (100) is fixed underwater through the fixing member (600) or the fixing member (600) and the connecting member, the fixing member (600) or the connecting member connected to the fixing member (600) may be damaged. Therefore, to prevent this, a buoyancy prevention means (130) may be additionally provided on the upper surface of the underwater tank (100).

[0098] Here, the buoyancy prevention means (130) may be composed of a metal or stone structure with a certain weight, for example, installed on the top of an underwater tank (100).

[0099] And since the structure is configured so that its weight corresponds to the maximum buoyancy that can be created within the underwater tank (100), when the buoyancy created within the underwater tank (100) is small, even if a force is generated to lower the underwater tank (100), the fixed member (600) or the connecting member connected to the fixed member (600) prevents the lowering of the underwater tank (100), and when the buoyancy created within the underwater tank (100) reaches its maximum and the fixed member (600) or the connecting member connected to the fixed member (600) is affected, the weight of the structure corresponds to the maximum buoyancy, thereby preventing the underwater tank (100) from rising, thereby preventing the fixed member (600) or the connecting member connected to the fixed member from being deformed or damaged when the buoyancy of the underwater tank (100) reaches its maximum and the rising force becomes strong.

[0100] The present invention, which is structured as described above, proposes a device that can effectively produce, store, and consume compressed air, as the supply of new and renewable energy is expanding in accordance with environmentally friendly policies of each country around the world, and as electric power energy storage technology is essential for stable supply and demand of electricity, and compressed air storage technology using compressed air is evaluated as the most effective technology among various storage technologies.

[0101] That is, since the end of the intake pipe (110) into which compressed air is introduced from the outside is located underwater inside the underwater tank (100), the air discharged from this intake pipe (110) passes through the water and is stored by buoyancy by being spread in the underwater tank (100) and the storage tank (200), and the compressed air introduced into the underwater tank (100) is affected by the water pressure regardless of the internal pressure of the underwater tank (100), so that even a low pressure can easily be introduced into the interior of the underwater tank (100).

[0102] In addition, the compressed air flowing into the intake pipe (110) can utilize renewable energy, thermal power, oil gas, nuclear power, or surplus electricity, and the compressed air produced in the underwater tank (100) can be supplied to cooling, heating, and necessary facilities by changing the temperature, or can drive a generator to produce electricity, so that the production, storage, and consumption of compressed air can be carried out simultaneously, thereby improving the efficiency of resource utilization.

[0103] In addition, the present invention stores compressed air stored in an underwater tank (100) and a storage tank (200) at a constant and high pressure by means of water pressure and buoyancy, and even if the amount of stored compressed air decreases due to the use of a large amount of compressed air, the air pressure in the underwater tank can be appropriately maintained by the action of water pressure and buoyancy, and compressed air can be continuously introduced from the outside when necessary. Therefore, this compressed air production and storage technology can be a complex and multi-purpose energy production and storage technology that satisfies all of the functions of compressed air collection, pressure increase, constant pressure maintenance, and storage, and thanks to this technology, an infinite amount of natural energy sources that were abandoned in nature can all be easily utilized as energy without damaging the environment, thereby producing eco-friendly renewable energy.

[0104] In addition, foreign substances can be removed without the need for a separate filter by passing through the water in the underwater tank (100), the heat generated during the compression process of air can be cooled without the use of a cooler, and the storage efficiency of the compressed air can be increased as the density increases.

[0105] While the detailed description of the present invention has described specific embodiments, it should be understood that various modifications are possible without departing from the scope of the disclosed subject matter. Therefore, the scope of the disclosed subject matter need not be limited to the described embodiments, but should be determined not only by the claims set forth below but also by equivalents thereof.
