Description

Technical Field

[0001] The present invention relates to the technical field of compressed air application for deep - sea platforms, and particularly to a gas cylinder inflation system for deep - sea platforms. Background Art

[0002] The compressed air system is one of the important systems to ensure the viability of deep - sea platforms. Its function is to manufacture, store and distribute high - pressure gas to meet the requirements of deep - sea platform diving, anti - sinking and supply gas to systems or devices that use compressed air. The compressed air system generally consists of an air compressor, a compressed gas distribution valve group, high - pressure air cylinders, pipelines and accessories. Among them, the air compressor is used to manufacture high - pressure air, and the distribution valve group stores the compressed gas in different high - pressure air cylinders respectively and supplies the compressed gas to different users. According to the user's usage requirements, generally more than two pressure levels of compressed air supply are required. For example, high - pressure air is required as the gas source for emergency blowing and surfacing at large depths, and low - pressure air is required as the gas source for normal blowing and surfacing near the water surface.

[0003] Currently, the existing technologies have the following problems and deficiencies;

[0004] Before the deep - sea platform dives, an air compressor is used to inflate the high - pressure air cylinders. The inflation needs to be carried out under the ventilation conditions on the water surface. During inflation, due to the temperature rise in the gas cylinder, the filling pressure will rise, which may cause the filling pressure of the gas cylinder to exceed the rated pressure, resulting in danger. Therefore, the platform often dives in a state where the gas cylinders are not fully filled. For conventional underwater platforms, the diving depth usually does not exceed 300m, and the temperature difference between the water surface and underwater is not large. The difference in the underwater pressure and water - surface pressure of the gas source caused by the temperature effect is also not large. For deep - sea platforms, the temperature difference between the water surface and underwater can reach more than twenty degrees Celsius. When diving to deep sea for use, due to the temperature difference between the water surface and underwater, the underwater pressure of the gas source is much smaller than the water - surface pressure of the gas source. During deep diving, it is often impossible to complete the specified actions such as emergency surfacing at large diving depths due to insufficient gas source pressure. Therefore, for deep - sea platforms, it is necessary to study methods to increase the water - surface filling pressure of gas cylinders to make the gas cylinders as full as possible on the water surface, while reducing the influence of temperature effect on the underwater pressure of the gas source and improving the comprehensive energy utilization efficiency of compressed air.

[0005] The low - pressure gas of traditional underwater platforms is generated by in - cabin low - pressure compressors or obtained by reducing the pressure of high - pressure gas. The use of low - pressure compressors needs to be carried out at the navigation depth of the ventilation pipe, which limits the usage conditions of low - pressure gas. The method of obtaining low - pressure gas by reducing the pressure of high - pressure gas has a large energy loss during the pressure - reduction process, and modern underwater platforms rarely use it.

[0006] Therefore, we propose a gas cylinder inflation system for deep - sea platforms. Summary of the Invention

[0007] In view of the above-mentioned drawbacks in the existing production technologies, the present applicant provides a deep-sea platform gas cylinder inflation system. By dividing the compressed air generated by an air compressor into two pressure levels and four temperature ranges, and through the control of a distribution valve group, heat transfer and exchange are carried out on the water surface and underwater, which not only effectively improves the filling pressure of the gas cylinder on the water surface, making the gas cylinder as full as possible on the water surface, but also reduces the influence of the temperature effect on the underwater pressure of the gas source.

[0008] The technical solution adopted by the present invention is as follows:

[0009] A deep-sea platform gas cylinder inflation system includes an air compressor, and also includes: connected in parallel with the air compressor through a main connection pipeline:

[0010] A primary high-pressure air cylinder for collecting high-pressure air;

[0011] A secondary high-pressure air cylinder for collecting high-pressure air;

[0012] A temperature control module, the structure of which includes:

[0013] A vortex tube that provides two kinds of low-pressure air at the cold end and the hot end with compressed air as the medium and power;

[0014] A primary low-pressure air cylinder connected to the cold end of the vortex tube through a cold-end pipeline for collecting cold-end low-pressure air;

[0015] A secondary low-pressure air cylinder connected to the hot end of the vortex tube through a hot-end pipeline for collecting hot-end low-pressure air;

[0016] Both the cold-end pipeline and the hot-end pipeline respectively act on the primary high-pressure air cylinder and the secondary high-pressure air cylinder through bypass pipelines controllably, and are used for refrigeration and preheating.

[0017] It is further characterized in that:

[0018] The secondary high-pressure air cylinder and the temperature control module share the same pipeline, and a shell-and-tube heat exchanger is connected to the front end of this pipeline. The shell-and-tube heat exchanger is connected to a seawater pump, and the high-pressure air is cooled by exchanging heat with seawater.

[0019] Coils are wound around both the primary high-pressure air cylinder and the secondary high-pressure air cylinder. The coils on the primary high-pressure air cylinder and the secondary high-pressure air cylinder are connected in series, and one end of this series-connected coil is connected in parallel with the cold-end pipeline and the hot-end pipeline, and the other end of this series-connected coil is communicated with the inside of the submersible for temperature adjustment.

[0020] Pressure and temperature measuring devices are provided on the connecting main pipelines of the primary high-pressure air cylinder, the secondary high-pressure air cylinder, the primary low-pressure air cylinder and the secondary low-pressure air cylinder.

[0021] On the main connecting pipelines of the primary high-pressure air cylinder, secondary high-pressure air cylinder, primary low-pressure air cylinder and secondary low-pressure air cylinder, a ballast tank is also connected through a branch pipeline for controlling the submersible to float. At the same time, the pipelines of the primary low-pressure air cylinder and secondary low-pressure air cylinder are also connected to the interior of the submersible for temperature adjustment.

[0022] Corresponding valves are provided on each pipeline.

[0023] The valves for controlling the opening and closing of the main connecting pipelines on the primary high-pressure air cylinder, secondary high-pressure air cylinder, primary low-pressure air cylinder and secondary low-pressure air cylinder are all close to the air inlet side, which is convenient for using the compressed air in each air cylinder separately.

[0024] The beneficial effects of the present invention are as follows:

[0025] The structure of the present invention is compact, reasonable and easy to operate. By dividing the compressed air generated by the air compressor into two pressure levels and four temperature ranges, and through the control of the distribution valve group, heat transfer and exchange are carried out on the water surface and underwater. Not only effectively improves the filling pressure of the air cylinder on the water surface, making the air cylinder as full as possible on the water surface, but also can reduce the influence of the temperature effect on the underwater pressure of the gas source. At the same time, the present invention uses a vortex tube as the generating device for low-pressure gas, so that the generation of low-pressure gas is no longer restricted by the navigation depth. Through the distribution and use of the low-pressure cold energy and low-pressure heat energy generated by the vortex tube, the comprehensive utilization efficiency of the compressed air on the water surface and underwater is improved.

[0026] At the same time, the present invention also has the following advantages:

[0027] 1. By setting a vortex tube, the vortex tube provides two kinds of low-pressure air at the cold end and the hot end with compressed air as the medium and power. The principle of vortex tube refrigeration is gas compression and expansion refrigeration, and the vortex tube has no rotating parts. The vortex tube has the advantages of simple structure, light weight, low cost, no moving parts and high reliability.

[0028] 2. The cold-end air generated by the vortex tube exchanges heat with the air in the primary high-pressure air cylinder and secondary high-pressure air cylinder, reducing the air filling temperature on the water surface of the air cylinder, making the air in the primary high-pressure air cylinder be high-pressure and slightly hot air, and the air in the secondary high-pressure air cylinder be high-pressure and normal-temperature air, effectively improving the filling pressure of the air cylinder on the water surface.

[0029] 3. Through the cold-end air generated by the vortex tube, the low-pressure deep cold air is directly output from the primary low-pressure air cylinder for adjusting the water surface temperature of the cabin, and the low-pressure slightly cold air flowing out from the outlet of the first coil can also be used for adjusting the water surface temperature of the cabin.

[0030] 4. The hot-end air generated by the vortex tube preheats the high-pressure air in the secondary high-pressure air bottle and the primary high-pressure air bottle, reducing the temperature difference between the air source under the water surface, decreasing the influence of the temperature effect on the underwater pressure of the air source, and effectively improving the underwater effective utilization efficiency of the high-pressure air.

[0031] 5. The hot-end air generated by the vortex tube, the low-pressure and weakly hot air is directly output from the secondary low-pressure air bottle for underwater temperature regulation of the cabin, and the low-pressure and slightly hot air flowing out from the outlet of the first coil can also be used for underwater temperature regulation of the cabin.

[0032] 6. When the platform suddenly encounters an accident and needs to emergently float, the high-pressure air in the primary high-pressure air bottle and the secondary high-pressure air bottle is used for emergency blow-off and floating at a large depth. After floating to a safe depth, the second control valve and the fourth control valve are closed.

[0033] 7. When the platform floats to near the water surface, the low-pressure air in the primary low-pressure air bottle and the secondary low-pressure air bottle is used for near-surface blow-off and floating. Description of the Drawings

[0043] The following combines with the attached drawings to illustrate the detailed implementation manners of the present invention.

[0044] Embodiment 1

[0045] As Figure 1 shown, this embodiment discloses a gas cylinder inflation system for a deep - sea platform, including an air compressor 1, a primary high - pressure air cylinder 6, a secondary high - pressure air cylinder 14, a primary low - pressure air cylinder 23, a secondary low - pressure air cylinder 29, and a vortex tube 17. Among them, the primary high - pressure air cylinder 6, the secondary high - pressure air cylinder 14, the primary low - pressure air cylinder 23, and the secondary low - pressure air cylinder 29 are used to store compressed air with different temperatures and pressures. The vortex tube 17 uses compressed air as a medium and power to generate two kinds of air with different temperatures. The low - temperature air generated by it is used to cool the primary high - pressure air cylinder 6 and the secondary high - pressure air cylinder 14, improving the inflation volume of the primary high - pressure air cylinder 6 and the secondary high - pressure air cylinder 14, while the high - temperature air is collected and utilized through the primary low - pressure air cylinder 23 and the secondary low - pressure air cylinder 29.

[0046] Among them, the air compressor 1 is connected in parallel with the primary high - pressure air cylinder 6, the secondary high - pressure air cylinder 14, and the temperature control module through the main connection pipeline. The structure of the temperature control module includes the vortex tube 17, the primary low - pressure air cylinder 23, and the secondary low - pressure air cylinder 29.

[0047] Among them, the vortex tube 17 provides two kinds of low - pressure air at the cold end and the hot end with compressed air as the medium and power. The refrigeration principle of the vortex tube 17 is gas compression - expansion refrigeration, and the vortex tube 17 has no rotating parts. Compressed air is tangentially conveyed into the vortex generator with spiral groove rings engraved inside by the vortex tube 17, where a rapid small air vortex is generated. The rotation speed of the air vortex can reach hundreds of thousands of revolutions per minute. In the center of the air vortex is cold air, which is ejected from one end of the vortex tube 17. After being led out through the conduit, it can be used for cooling. Around the air vortex, the air moves along the spiral line of the vortex tube 17, and heat is generated under the action of friction and momentum exchange, thus forming hot air that is ejected from the throttle valve at the other end of the nozzle. The vortex tube 17 has the advantages of simple structure, light weight, low cost, no moving parts, and high reliability.

[0048] The primary low - pressure air cylinder 23 is connected to the cold end of the vortex tube 17 through the cold - end pipeline for collecting the cold - end low - pressure air;

[0049] The secondary low - pressure air cylinder 29 is connected to the hot end of the vortex tube 17 through the hot - end pipeline for collecting the hot - end low - pressure air;

[0050] The cold-end pipeline and the hot-end pipeline respectively act on the primary high-pressure air bottle 6 and the secondary high-pressure air bottle 14 through the bypass pipelines in a controllable manner, and are used for refrigeration and preheating.

[0051] The secondary high-pressure air bottle 14 and the temperature control module share the same pipeline, and a shell-and-tube heat exchanger 8 is connected to the front end of this pipeline. The shell-and-tube heat exchanger 8 is connected to the seawater pump 9, and the high-pressure air is cooled by exchanging heat with seawater.

[0052] Coiled pipes are wound around both the primary high-pressure air bottle 6 and the secondary high-pressure air bottle 14. The coiled pipes on the primary high-pressure air bottle 6 and the secondary high-pressure air bottle 14 are connected in series. One end of the series-connected coiled pipes is connected in parallel to the cold-end pipeline and the hot-end pipeline, and the other end of the series-connected coiled pipes is communicated with the inside of the submersible for temperature regulation.

[0053] Pressure and temperature measuring devices are provided on the main connecting pipelines of the primary high-pressure air bottle 6, the secondary high-pressure air bottle 14, the primary low-pressure air bottle 23, and the secondary low-pressure air bottle 29.

[0054] The main connecting pipelines of the primary high-pressure air bottle 6, the secondary high-pressure air bottle 14, the primary low-pressure air bottle 23, and the secondary low-pressure air bottle 29 are also communicated with the ballast tank through bypass pipelines for controlling the floating of the submersible. At the same time, the pipelines of the primary low-pressure air bottle 23 and the secondary low-pressure air bottle 29 can also be directly connected to the inside of the submersible for temperature regulation.

[0055] Corresponding valves are provided on each pipeline. The valves controlling the opening and closing of the main connecting pipelines on the primary high-pressure air bottle 6, the secondary high-pressure air bottle 14, the primary low-pressure air bottle 23, and the secondary low-pressure air bottle 29 are all close to the intake side, which is convenient for using the compressed air in each air bottle separately.

[0056] Embodiment 2

[0057] In this embodiment, the structure and working mechanism of the device are specifically described.

[0058] As Figure 1 shown, the air compressor 1 is used as a gas-producing device. The high-pressure gas generated is divided into two streams. The first stream of high-pressure gas enters the primary high-pressure air bottle 6 for storage through the first control valve 2. A first pressure gauge 3 and a first thermometer 4 are provided near the primary high-pressure air bottle 6 on the first stream of high-pressure gas pipeline to monitor the temperature and pressure of the gas in the primary high-pressure air bottle 6. At the same time, a second control valve 5 is provided on the first stream of high-pressure gas pipeline to control the use of the gas in the primary high-pressure air bottle 6. The primary high-pressure air bottle 6 is placed inside the first coiled pipe 7.

[0059] The second high-pressure gas generated exchanges heat with seawater through the shell-and-tube heat exchanger 8, and the seawater for heat exchange is driven by the seawater pump 9. The high-pressure gas flowing out of the shell-and-tube heat exchanger 8 is divided into two streams. One of them enters the secondary high-pressure air bottle 14 through the third control valve 10 for storage. A second pressure gauge 11 and a second thermometer 12 are arranged near the secondary high-pressure air bottle 14 on this high-pressure gas pipeline to monitor the temperature and pressure of the gas in the secondary high-pressure air bottle 14. At the same time, a fourth control valve 13 is arranged on this high-pressure gas pipeline to control the use of the gas in the secondary high-pressure air bottle 14. The secondary high-pressure air bottle 14 is placed inside the second coiled pipe 15.

[0060] The other high-pressure gas flowing out of the shell-and-tube heat exchanger 8 is divided into two cold and hot low-pressure gases after passing through the vortex tube control valve 16 and the vortex tube 17. The low-pressure cold air enters the primary low-pressure air bottle 23 through the fifth control valve 18 for storage. A third pressure gauge 20 and a third thermometer 21 are arranged near the primary low-pressure air bottle 23 on the low-pressure cold air pipeline to monitor the temperature and pressure of the gas in the primary low-pressure air bottle 23. At the same time, a front-end cold air control valve 19 and a rear-end cold air control valve 22 are arranged on the low-pressure cold air pipeline to control the use of the gas in the primary low-pressure air bottle 23.

[0061] The low-pressure hot air enters the secondary low-pressure air bottle 29 through the sixth control valve 24 for storage. A fourth pressure gauge 26 and a fourth thermometer 27 are arranged near the secondary low-pressure air bottle 29 on the low-pressure hot air pipeline to monitor the temperature and pressure of the gas in the secondary low-pressure air bottle 29. At the same time, a front-end hot air control valve 25 and a rear-end hot air control valve 28 are arranged on the low-pressure hot air pipeline to control the use of the gas in the secondary low-pressure air bottle 29.

[0062] The front-end cold air control valve 19 and the front-end hot air control valve 25 are both connected to the inlet of the second coiled pipe 15 through pipelines, and the outlet of the second coiled pipe 15 is connected to the inlet of the first coiled pipe 7 through a pipeline.

[0063] Specifically, the primary high-pressure air bottle 6 and the secondary high-pressure air bottle 14 are high-pressure air bottles with a nominal working pressure ≥ 8 MPa, and the primary low-pressure air bottle 23 and the secondary low-pressure air bottle 29 are low-pressure air bottles with a nominal working pressure ≤ 5 MPa. The design temperature of the primary low-pressure air bottle 23 ≤ -60 °C, and the design temperature of the secondary low-pressure air bottle 29 ≥ 150 °C.

[0064] The temperature T0 of the low-pressure hot air in the secondary low-pressure air bottle 29 > the temperature T1 of the high-pressure slightly hot air in the primary high-pressure air bottle 6 > the temperature T2 of the high-pressure normal-temperature air in the secondary high-pressure air bottle 14 > the temperature T3 of the low-pressure cold air in the primary low-pressure air bottle 23.

[0065] The specific working principle is as follows:

[0066] Surface operation: When the platform is in the surface state, start the seawater pump 9 and start the air compressor 1 to produce gas. First, open the vortex tube control valve 16, the fifth control valve 18, and the sixth control valve 24. The high-pressure gas is divided into two low-pressure gas streams, hot and cold, by the vortex tube 17 and stored in the primary low-pressure air bottle 23 and the secondary low-pressure air bottle 29 respectively.

[0067] Then open the front-end cold air control valve 19. The low-pressure deep cold air pre-cools the secondary high-pressure air bottle 14 and the primary high-pressure air bottle 6 through the second coil 15 and the first coil 7.

[0068] Subsequently, open the first control valve 2 and the third control valve 10 to fill the primary high-pressure air bottle 6 and the secondary high-pressure air bottle 14 respectively. During this process, the front-end cold air control valve 19 is always open to cool the air filling at the water surface of the air bottle (air bottle water surface filling cooling FD), reducing the air filling temperature at the water surface of the air bottle, so that the primary high-pressure air bottle 6 contains high-pressure and slightly hot air, and the secondary high-pressure air bottle 14 contains high-pressure and normal-temperature air, effectively increasing the water surface filling pressure of the air bottle.

[0069] Open the rear-end cold air control valve 22. The low-pressure deep cold air is directly output from the primary low-pressure air bottle 23 for regulating the water surface temperature of the cabin (cabin water surface temperature regulation / near water surface blowing and purging for surfacing FF). The low-pressure slightly cold air flowing out from the outlet of the first coil 7 can also be used for regulating the water surface temperature of the cabin (cabin water surface or underwater temperature regulation FB).

[0070] When the primary high-pressure air bottle 6 is full, close the first control valve 2; after the secondary high-pressure air bottle 14 is full, close the third control valve 10; then close the air compressor 1 and the seawater pump 9, close the vortex tube control valve 16, the fifth control valve 18, and the sixth control valve 24, close the front-end cold air control valve 19 and the rear-end cold air control valve 22, and then the platform dives.

[0071] Underwater operation: When the platform is in the underwater state, open the front-end hot air control valve 25. The low-pressure strong hot air pre-heats the high-pressure gas in the secondary high-pressure air bottle 14 and the primary high-pressure air bottle 6 through the second coil 15 and the first coil 7 (cabin water surface temperature regulation / near water surface blowing and purging for surfacing FE), reducing the temperature difference between the air source underwater and at the water surface, reducing the influence of temperature effect on the underwater pressure of the air source, and effectively increasing the underwater effective utilization efficiency of the high-pressure air.

[0072] At the same time, open the rear-end hot air control valve 28. The low-pressure strong hot air is directly output from the secondary low-pressure air bottle 29 for regulating the underwater temperature of the cabin (cabin underwater temperature regulation / near water surface blowing and purging for surfacing FG). The low-pressure slightly hot air flowing out from the outlet of the first coil 7 can also be used for regulating the underwater temperature of the cabin (cabin water surface or underwater temperature regulation FB).

[0073] When the platform floats upward, the temperature will rise, and it is necessary to close the front-end hot gas control valve 25 and the rear-end hot gas control valve 28, and temperature adjustment is no longer required.

[0074] When the platform encounters an accident and needs to float upward emergently, open the second control valve 5 and the fourth control valve 13, and use the high-pressure air in the primary high-pressure air cylinder 6 and the secondary high-pressure air cylinder 14 for emergency blow-off and upward floating at a large depth (emergency blow-off and upward floating FA and emergency blow-off and upward floating FC at a large depth). After floating to a safe depth, close the second control valve 5 and the fourth control valve 13.

[0075] When the platform floats to near the water surface, open the rear-end cold gas control valve 22 and the rear-end hot gas control valve 28, and use the low-pressure air in the primary low-pressure air cylinder 23 and the secondary low-pressure air cylinder 29 for near-water surface blow-off and upward floating (cabin water surface temperature adjustment / near-water surface blow-off and upward floating FF and cabin underwater temperature adjustment / near-water surface blow-off and upward floating FG). After floating to the water surface, close the rear-end cold gas control valve 22 and the rear-end hot gas control valve 28.

[0076] In view of the above-mentioned shortcomings in the above production technology, the applicant proposes a method for filling air cylinders of a deep-sea platform and a strategy for using compressed air, which divides the compressed air generated by the air compressor 1 into two pressure levels and four temperature ranges. Through the control of the distribution valve group, heat transfer and exchange are carried out on the water surface and underwater, which not only effectively increases the filling pressure of the air cylinders on the water surface, making the air cylinders as full as possible on the water surface, but also reduces the influence of the temperature effect on the underwater pressure of the gas source. The invention uses the vortex tube 17 as the device for generating low-pressure gas, providing a new idea for generating low-pressure gas on a deep-sea platform, so that the generation of low-pressure gas is no longer restricted by the navigation depth. Through the distribution and use of the low-pressure cold energy and low-pressure heat energy generated by the vortex tube 17, the comprehensive utilization efficiency of compressed air on the water surface and underwater is improved.
