1. The technical FIELD

The present invention relates to a system that can extract superheated fluids from deep ocean hydrothermal channels, as well as the use of such fluids as a source of thermal energy. The system is configured to direct surface flow of superheated deep ocean hydrothermal fluid through a reliable mechanism with a view to its use by any other mechanism that requires the application of heat, for example, when the production of electricity or water desalination. In addition, this system provides a reliable mechanism to retrieve from the bottom of the ocean resources such as metals and minerals, and this can be done without modification simultaneously with the extraction of thermal energy or separately from it.

2. The LEVEL of TECHNOLOGY

Global demand for energy and fresh water is constantly growing, therefore becoming increasingly difficult to find new sources of energy and fresh water and to carry out their supply to consumers. The problem of global warming and excessive greenhouse gas emissions, as well as the high cost of extraction of fossil fuels makes renewable clean energy is very important. In the present description for the first time shows how the maximum use of this non abaimova natural energy source.

Development of deposits on the surface of the Earth is difficult and costly, and due to the political instability access to the necessary resources in some regions of the globe is limited. Until recently, the extraction of ocean bottom large amounts of minerals remained only a dream. In the present description for the first time presents a system that provides a practical tool to extract these resources.

Heat is the main form of energy. The heat supplied by the combustion of oil or coal, or emitted in the nuclear reaction, or emanating from the magma of the Earth, is that eventually accompanies the process of electricity generation almost all types of desalination process and other processes.

At the bottom of the seas and oceans in different parts of the globe, scientists have discovered hydrothermal channels. Under the action of deep-water pressure in cracks on the ocean floor is forced oceanic water that eventually reaches the Earth's core. This water, superheated magma temperatures of over 400°C (750°F), as a result of passage through the earth's depths enriched in rare elements. A continuous flow of such hot water through hydrothermal channels goes back into the ocean with a speed of from 1 to 5 m/s (3,6-18 km/h, or 2,25-11 miles per hour). It is estimated that th is energy, released only from known hydrothermal channels is 17000000 megawatts per year, which is approximately equal to the electricity consumption of all mankind throughout the year. It should also be noted that hydrothermal channels may be located on the square in the tens of thousands who have never before studied square miles of the ocean floor.

In the following description, applied the term "fluid"as the water coming through the hydrothermal channels back into the ocean, though mainly consists of sea water, still differs significantly from the surrounding seawater chemical composition due to exposure to the effects of magma.

Currently, there are several inventions related to the extraction of geothermal energy, but none of them was stated to retrieve hydrothermal energy. None of the known inventions does not apply to any use of natural hot sea water or other fluids from hydrothermal channels under the ocean bottom or to the delivery of such oceanic fluid to the surface in the overheated state with the purpose of obtaining a preferential temperature differences for heat recovery.

In addition, not previously submitted applications for patenting system to retrieve from the ocean floor minerals, metals or khimicheskaia. At the current level of technology not identified patents, as opposed to the present invention. Below are the following patents:

1. In one of the inventions (U.S. patent No. 5,515,679) the proposed device and methods of delivery to the surface of thermal energy found in the underground heated rock. However, the structure of the rock is fundamentally different from the structure of the ocean floor. Due to thermal conductivity, the heat is transferred to the working fluid through the walls uninsulated pipe along the entire length are in direct contact with the breed. However, in the present invention as a heat source used natural oceanic fluid from hydrothermal channels,and heat is introduced into the system only at the bottom of the ocean. In addition, the present invention describes a device for the extraction of mineral resources from the ocean floor, and this can be done without modifying the system.

2. In another prior invention (U.S. patent No. 4,054,176) the proposed system for conversion into electricity geothermal energy derived from the heat flow through the solid matter of the rocks. The system described in this patent, receives heat by the way, is very similar to the method described in U.S. patent No. 5,515,679. However, in the present invention heat centuries is implemented in the system only in its lower part. In addition, U.S. patent No. 4,054,176 limited to just convert this heat energy into electricity. However, in the present invention, the energy from hydrothermal channels may be used for generating electricity or for desalination or for any other proceeding requiring the use of thermal energy; in addition, this invention provides the ability to extract mineral resources from the ocean floor without system modifications.

DETAILED DESCRIPTION of PREFERRED embodiments of the PRESENT INVENTION

The following is a detailed description of the preferred embodiments of the present invention with reference to accompanying drawings. However, the present invention can be implemented in many different but related forms; one should not assume that it is only limited options for implementation in the present about what Isani. These options rather contribute to a more complete and detailed disclosure of the invention. In addition, these implementations contribute to a clear understanding of the specialist subject of the invention at all the drawings, identical or similar elements are denoted by the same numbers.

Under normal conditions the fluid, superheated by magma erupts into the ocean, with its heat energy is quickly dissipated in the cold ocean water 2°C (35°F) and is carried away by ocean currents. Due to the extremely high content in fluid minerals these minerals precipitate from the fluid and deposited on the ocean floor around the hydrothermal vents of the channel. According to the present invention, a superheated fluid, rich in minerals, catch discharging means for transporting it to the surface before it has cooled down under the influence of the environment or react with it. Hydrothermal fluid rises from the ocean floor to the surface of the ocean on the big pipe manufactured with reinforced insulation, due to the speed of flow, convection, conduction and pressure flash evaporation, stems from the fact that the ambient pressure decreases as the heated water rises, and due to a lower density and a significant amount of teplovodenergia, contained in the fluid. You can also use the pump on the surface to increase the speed of flow of hydrothermal fluid to the surface in a way compatible with the pipe with a heat differential gain, the description of which is given below.

Hydrothermal channels (15) are located at a depth of approximately 2300 m (7500 ft); they can be found anywhere along the mid-oceanic ridges, stretching 72000 km (45000 miles).

The purpose of the research and development of this natural phenomenon with the vessel lower structure (10)having a conical frame and containing a large funnel (12)connected to the sections (13) isolated tube over the channel (15)at the bottom of the ocean. Funnel (12) made of a heavy material with reinforced insulation and the diameter of the outlet part to three feet or more, depending on the size of the channel (15) and flow rate of the fluid, while the bell of the funnel (12) has a considerable width.

Preferably the mouth of the funnel (12) must be enclosed inside a conical structure (10) or other similar structure (not shown), which would hold the funnel (12) and attached pipe section, in a safe position above the hydrothermal channel. Funnel (12) serves as an auxiliary device for collection of superheated fluid (11); in addition, it acts as a Tr the BKA Venturi to increase the velocity of fluid flow within the section (13) of the pipe. Increasing the speed increases the amount of thermal energy leaving the surface.

First hydrothermal over the channel by means of conical structures (10) install the funnel (12) and the initial section (13) of the pipe, then section (13) of the hollow cylindrical tube made of the same heavy material with reinforced insulation, one by one down on the top of the structure (10) and the initial section (13) and thus collect a vertical pipe extending to the surface. Each subsequent section (13) of the pipe attached to the previous section (13) by means of a tapered V-shaped gravitational compaction, or the flange-bolted connection, or by any combination of several traditional methods of mechanical fastening. Figure 5 as an example, shows one implementation options. To connect you can use latches or other mechanisms spring type, as well as welding, with optimal mechanical connection of the segments should be determined on the basis of practical application. Each pipe section (13) should be provided with a device to keep it afloat, for example, dockable floating cuff (17), which should be in the pressurized state to provide more than 95% buoyancy. This minimizes the total weight of the priori conical structure (10) on the bottom of the ocean, and also provides vertical stability, as any tilting of the pipe will tend to self-correct. In addition, to stabilize the vertical pipe column (13) can be used fastening cables (not shown) after a certain period.

Pipe section (13) connected in a continuous chain, until then, until it is collected long pipe with reinforced insulation, the length from the bottom (18) of the ocean to the surface (16) of the ocean. Since the fluid pressure inside the pipe (13) in its lower part is equal to the external pressure, there is no need to perform special calculations for Assembly of the pipe (13), able to withstand extreme deep ocean pressure. Inside the pipe, the pressure can be higher than the pressure of the ocean, approaching fluid to the surface. As shown in figure 4, by joining pipe sections (13) can be formed pipe with reinforced insulation, capable of conveying superheated fluid (11) on the surface (16) of the ocean, after which thermal energy contained in the fluid, can be used to drive steam turbines or other equipment intended for the formation of (110) electricity, desalination (150) of water or for any other proceeding requiring the use of thermal energy; in addition, the fluid can simultaneously is whether to separately flow into the equipment (152) for resource extraction to extract a valuable minerals, metals and chemicals, as shown in figure 4. In the lower part of the tube can be mounted valve with electric or mechanical drive (not shown) for interrupting the flow of fluid when carrying out installation or maintenance work.

Thanks reinforced insulation sections (13) of the pipe fluid (11) remains isolated from ocean currents and cold water. Due to the fact that there is no loss of heat, the fluid (11) remains hot. The stacked section (13) of the pipe reaches the surface (16) of the ocean, while the whole system is conceptually similar to a giant pot with good insulation, the lower part of which is a heat source that supports the column of fluid in a heated state. Thus superheated fluid (11) flows through the pipe to the surface (16) of the ocean with little heat loss as compared to the initial temperature of the fluid in the lower part of the tube. The only loss will be the loss of heat leaked through the insulation. Obviously, a certain amount of heat will add friction of the fluid (11) inside the pipe (13).

When superheated fluid (11), rising through the pipe to reach the surface (16) of the ocean, you can apply any practical way to use the contained heat. If at the place of exit of the fluid on the surface of the produced electricity, e the need to deliver on land use of submarine cables or other means. It is assumed serial and parallel connection serial thermal energy systems up until all the heat contained in the fluid and subject extraction will not be converted into useful work. Then the remaining fluid (11) return the depth of the ocean to the place of its origin using uninsulated return pipe (26).

Figure 3 shows an alternative method of delivering superheated working fluid (39) on the surface (16) of the ocean, when using a closed system filled with clear fluid, liquid or gas (39), while the lower part of the heat exchanger (38) is installed on the output of hydrothermal channel and exposed to heat directly from him. Net working fluid heated within the heat exchanger (38), also protected by insulated pipes (13), which delivers superheated fluid to the surface to convert the contained heat, after which the fluid is sent back, driven by natural convection and / or return pumps (40), return pipe (44), insulated to retain heat remaining in the working fluid, and for re-heating fluid inside the heat exchanger to even higher temperatures.

In addition, the tube (19) with thermal differential amplification can be used in the open, the AK and in a closed system to increase the temperature difference and to increase thereby the amount of energy that arriving on the surface of the ocean. The system contains nothing but isolated tube, open at both ends and stretched up from the bottom (18) of the ocean and a few feet protruding above the surface (16), so that the water on the surface do not mix with the water contained in the pipe.

Through the open upper part of the inside of the pipe is placed a pump (32) for cold water, this pump is used for cold part of any system designed to extract heat energy. As water is pumped out of the pipe, the pipe again fills the atmospheric pressure; this occurs at a single point, the open side of the ocean, at the bottom, where the water temperature is approximately 2°C (35°F). Within a short period of time, the only water inside the pipe with reinforced insulation is water flowing in a pipe at the bottom. The use of such very cold water instead of atmospheric air or water from the surface to a cold part of any system for extracting energy significantly increases the amount of thermal energy due to the increase in full the difference in temperature compared to ambient temperature at 15°C and more.

In the preferred implementation shown in figure 4, the platform (24), similar to the oil platform, have there where the pipe (13) reaches the surface and (16); it set up the equipment (110, 150) to extract energy and/or equipment (152) to extract resources. For the purpose of holding the platform in position on the pipe (13) you can use the platform with legs stretched or semi-submersible platform with both static and dynamic positioning, as well as some other technologies. In addition, instead of platforms you can use the court.

Hydrothermal channels (15) are available in different configurations, so for sampling of hydrothermal fluid (11) use different implementations.

Some hydrothermal channels (15)along an underwater mountain ridge Juan de Fuca approximately 200 miles off the coast of Oregon, have a diameter of 30 m (100 feet) or more. A preferred embodiment for such cases, when the hydrothermal channels is very large, as shown in figure 1.

First, you need to create a detailed topographic map of the bottom (18) of the ocean, surrounding hydrothermal channel (15). Figure 1 and 2 shows the profile embedded in the lower part of the ring (33). Ring (33) must be large enough to completely surround the hydrothermal channel (15), after installation of the ring (33) at his position, it must provide a hard and smooth surface, which will make installation, regardless of the irregularities of the bottom (18) of eana, under the ring. Through the lower ring (33) in an indigenous breed can drill holes for anchors (not shown), if needed to secure the conical structure (10) at the bottom (18) of the ocean.

Inside the ring (33) is attached specialissue beams (41), resembling the spokes of a wheel, located radially between the inner perimeter of the ring (33) and the outer perimeter of the pipe (13). Thus provide a support and centering the lower section (13) of the pipe, inside the hydrothermal vents of the channel, if it is too large. These horizontal bars (41) not support the weight of the entire column mounted pipe, and only the weight of the pipe section (13)to which they are attached. Specified first (lower) section (13) of the pipe is positioned so that it is as deep as possible was included in the center of hydrothermal channel (15) with the purpose of extraction fluid (11) at the highest possible temperature. Under such conditions, a funnel (12) in the lower part acts as a Venturi and increases the speed of the fluid inside the pipe (13), like the nozzle of a garden hose increases the flow rate coming out of the water. This increased speed increases the amount of energy arriving at the surface (16).

Several angled supports (54) fasten the largest ring (33) with multiple concentration is practical rings (50, 51 and 52) of smaller diameter and support each of them at a higher point above the bottom (18) of the ocean.

The vertical distance between these rings is equal to the height of one section (13) of the pipe.

Resembling the spokes of a wheel crossbars (41) with specialises configuration within the specified ring support and centering of the second section (13) of the pipe, which is then attached to the lower section (13) of the pipe. This process is carried out by adding other concentric rings (51 and 52) of smaller diameter attached using the supports (54) to the second ring of larger diameter, each ring of smaller diameter have a higher altitude compared to the previous. Each ring has its own specialissima rungs (41), which radiate from the center. These beams support the weight of only one pipe section (13)to which they are attached. You can use several progressive decreasing concentric rings to increase the height of the conical structure (10) as you add rings.

Eventually you will reach the desired diameter of the smallest ring (72), when its inner diameter is equal to the outer diameter of the tube (13); this segment at the top (72) of the cone will take the weight of the column pipe above. Then the load will see the request on the ring with the smallest diameter and, by means of supports (54)holding together all rings with conical structures, located underneath the ring of larger diameter, and so on up until the load is not distributed evenly and will not move on the ring (33) with the greatest diameter, located in the lower part and on the bottom (18) of the ocean beneath it.

All conical structure (10) with pipe sections (13) in the center and a funnel (12) can be collected (although not necessarily) on Board the vessel or on the ground object, and then assembled to put it in the position at the bottom of the ocean, with the first bearing section (13) of the pipe, and then to assemble the subsequent sections.

In another embodiment, the implementation shown in figure 2, a large conical structure (10)as described above may be modified for use in areas containing many small hydrothermal channels (15)located in a limited geographical area. Possible intake of a large volume of fluid (11) of several hydrothermal channels (15) for delivery to the surface by combining the outputs of many small hydrothermal channels (15) and sampling from them fluid, and through tie-insulated pipes (99) of smaller diameter in one large insulated pipe (13) at the top (72) conical structures (10). In addition, to make the design, the functions added stability through the lower ring (33) in the ocean bottom can be used to drill holes for anchors (not shown).

In addition, the present invention in an unmodified form provides a reliable delivery mechanism saturated resources of the fluid (11) on the surface. Such a system for resource extraction is shown in figure 4.

Most hot hydrothermal channels, or so-called "black smokers", a large number of contain many valuable metals, minerals and chemical substances, including iron, gold, silver, copper, zinc, cadmium, manganese and sulfur, as well as significant amounts of methane gas mixed with the fluid. In addition, these hydrothermal channels in abundance include the halides, sulfates, chromates, molybdates and wolframates. The fluid (11) rises through the pipe (13); together with fluid on the surface rise contained in the minerals and metals. The fluid enters the equipment (152) to extract the resource, or it is poured into containers and transported on ships for processing on land. Excess hot fluid and unwanted minerals and products remaining after the extraction of thermal energy or resources, return back to the bottom of the ocean on a similar, but non-insulated terminal tube (26)which is not located above the hydrothermal channel. You can use any equipment for the extraction of resources depending on the particular extract or other substance. P. and necessary to carry out the extraction of resources regardless of the extraction of thermal energy.

Figure 3 shows a closed system for the extraction of hydrothermal energy. In this case, the platform (24) can also be used, as shown in figure 4. Hydrothermal power plant (110), as shown in figure 3, works together with a desalination plant (150) for desalination. When retrieving the resource itself hydrothermal fluid rises through the pipe to the surface. Thermal energy is transferred to the working fluid via a heat exchanger, and then this heated fluid is used to generate electricity, desalinate water, or for any other production, requiring application of heat energy before it is returned to the bottom of the ocean for reheating.

On figa and 5B shows a flexible connection of pipes, which can be used in the present invention. On figa shows a pair of sections (200) and (202) pipe, the upper end of the section (202) is connected with the lower end of the section (200). The lower end of the section (200) may have protruding outward flange (204); similarly the upper end of the pipe may have protruding outward flange (206). Between these pipe sections inserted a spring-loaded mechanism (208), provide flexible connection for moving the two pipe sections relative to each other in case of exposure to the influence of ocean currents. This g is bcoe a secure connection of the inner part of the pipe and its contents.

FIELD: heating.

SUBSTANCE: when implementing the method during the heating period, low-potential heat is removed from soil. Supply of liquid heat carrier is performed through soil layers by means of the main closed circulating system with closed-type vertical loops installed by means of wells. Then, heat is transferred so that it is converted by means of a heat-pump cycle to a higher temperature level to the heat supply network of the power supply site. During the non-heating period, accumulation of external heat discharges in the soil is selected and supply of heat carrier through the soil layers is changed over to an additional closed circulating system with an intermediate heat exchanger for utilisation of heat discharges, which is installed into it. When changing over from heat removal to accumulation of heat discharges, depth of heat carrier supply is changed through the soil layers from intersection level of vertical loops of one or several water-bearing soil layers to the level above the roof of upper water-bearing layer. For that purpose, some part of the loops used for heat extraction from soil is used at heat extraction and accumulation of heat discharges as per a shortened version by installing those loops as a part of the additional circulating system with the length corresponding to the second of the above levels. The rest loops are installed as a part of the main circulating system with the length corresponding to the first level. When changing over from the soil heat extraction to accumulation of heat discharges, the method allows changing heat carrier supply depth through the soil layer from the intersection level of vertical loops as a part of the main circulating system of one or several water-bearing soil layers to the level above the roof of upper water-bearing layer, thus installing vertical loops in compliance with the last level as a part of the additional circulating system, the length of which is chosen as shortened relative to that one which is chosen in compliance with the first level of length of loops of the main circulating system. The task of the seasonal change of levels is solved either by using known structural designs with wells of various depths as a part of loops, or based on the proposed design of the downhole heat exchanger.

EFFECT: more effective seasonal change of levels.
