Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide storage, and in particular to a wave-type carbon dioxide storage device. Background Art

[0002] Studies have shown that the exchange rate between seawater and CO2 at the sea-air interface is very slow and limited to the surface / subsurface seawater. At present, the CO2 in the warmer surface seawater of the global ocean is saturated, while the low-temperature deep seawater is unsaturated and has a huge CO2 solubility capacity, which shows that the deep seawater has a huge carbon sequestration capacity. However, for the solidification of carbon dioxide, people usually reduce the emission of carbon dioxide from the source based on the concept of environmental protection, but there is no solution to seal carbon dioxide through seawater, so that there is no device in the prior art that can effectively use seawater to seal carbon dioxide. In addition, although there are gradually emerging solutions for extracting deep seawater for carbon dioxide sequestration based on hydraulic equipment, they usually use self-generating equipment to drive the hydraulic equipment, and self-generating equipment is prone to failure in harsh marine environments, resulting in an inability to provide stable power supply, and thus unable to achieve continuous and stable extraction of deep seawater.

[0003] Therefore, there is an urgent need for a wave-type carbon dioxide storage device to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that there is a lack of effective carbon dioxide storage devices in the prior art and that the existing carbon dioxide storage devices are unable to continuously and stably store carbon dioxide, and to provide a wave-type carbon dioxide storage device.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a wave-type carbon dioxide storage device, which includes a working pipe and a fixing part. One end of the working pipe is inserted into the seabed in a vertical direction, and the other end extends in the coastal plane direction and is connected to an end of a buoy positioning frame located below the sea level. The buoy is arranged in the buoy positioning frame, and its bottom is connected to a pump inner cylinder slidably arranged in a pump outer cylinder of the working pipe through a pump rod. A sealing ring is arranged between the outer side of the pump inner cylinder and the inner side of the pump outer cylinder. A floating valve is arranged in the pump inner cylinder. A fixed valve is arranged inside the working pipe below the pump outer cylinder. The fixing part is used to fix the working pipe to the seabed.

[0006] Preferably, the diameter of the buoy positioning frame is larger than the diameter of the buoy, and the difference between the two is 1-5 cm.

[0009] Preferably, a plurality of centralizers are spaced apart between the outer surface of the pump rod and the inner surface of the working tube.

[0010] Preferably, two movable valves are arranged in the inner cylinder of the pump from top to bottom.

[0011] Preferably, the fixing member is a fixing plate and / or an anchor chain, and a plurality of the fixing plates are used to fix the working pipe on the offshore platform; one end of a plurality of the anchor chains is arranged around the working pipe and connected to the seabed, and the other end is connected to the working pipe.

[0012] Preferably, it also includes a spirit level arranged on the top of the buoy positioning frame, the spirit level includes a solar power supply module, a wireless transmission module and an alarm module, which is used to send out an alarm message through the wireless transmission module and make an on-site alarm through the alarm module when the working pipe deviates from the set angle in the vertical direction.

[0019] The specific implementation of the embodiment of the present invention is described in detail below. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0020] In the description of the present application, the term “comprise” and any variations thereof mean non-exclusive inclusion, possible existence or addition of one or more other features, units, components and / or combinations thereof.

[0021] In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internally connected between two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] The present invention provides a wave-type carbon dioxide storage device, such as Figure 1 As shown, the wave-type carbon dioxide storage device includes a working pipe 4 and a fixing member. One end of the working pipe 4 is inserted into the seabed in a vertical direction, and the other end extends in a coastal plane direction and is connected to an end of a buoy positioning frame 13 located below the sea level. The buoy 1 is arranged in the buoy positioning frame 13, and its bottom is connected to a pump inner cylinder 10 slidably arranged in a pump outer cylinder 7 of the working pipe 4 through a pump rod 3. A sealing ring 11 is arranged between the outer side of the pump inner cylinder 10 and the inner side of the pump outer cylinder 7. A floating valve 8 is arranged in the pump inner cylinder 10. A fixed valve 9 is arranged inside the working pipe 4 located below the pump outer cylinder 7. The fixing member is used to fix the working pipe 4 in the seabed. Among them, the buoy positioning frame 13 is hollowed out around so that seawater can enter and drive the buoy 1 to float up and down with the waves. When the buoy 1 is not pushed upward by the buoyancy of seawater waves, the pump inner cylinder 10 connected to it through the pump rod 3 is at the bottom of the pump outer cylinder 7 under the action of gravity.

[0023] According to the above technical scheme, based on the wave-type carbon dioxide storage device, in actual application, the working pipe is inserted into the seabed and fixed under the action of the fixing parts, and the buoy drives the pump inner cylinder to move up and down in the pump outer cylinder through the pump rod under the drive of the waves and the vertical limit of the buoy positioning frame, forming a piston effect, and then the deep seawater is continuously pumped out of the sea surface for dissolving carbon dioxide, which has the advantages of good economy, stability and reliability.

[0024] In the wave-type carbon dioxide storage device described in the present invention, preferably, the diameter of the buoy positioning frame 13 is larger than the diameter of the buoy 1, and the difference between the two is 1-5 cm, so that the buoy 1 can only move up and down along the buoy positioning frame 13 under the action of waves, and will not be horizontally offset, causing the pump rod 3 to bend or even break, thereby causing the extraction process of the middle and deep seawater to be interrupted.

[0025] In the wave-type carbon dioxide storage device described in the present invention, preferably, the interior of the buoy 1 extending from the middle of the bottom toward the top is provided with upflow holes with gradually decreasing diameters but does not penetrate the buoy 1, so that the rising height of the buoy 1 can be increased when the waves rise, thereby improving the extraction efficiency of the middle and deep seawater.

[0026] In the wave-type carbon dioxide storage device described in the present invention, preferably, one end of the pump rod 3 is connected to the bottom of the upflow hole of the buoy 1, and the other end is connected to the middle of the top of the pump inner cylinder 10, so that the rising height of the buoy 1 under the action of waves is further improved based on the umbrella-like structure, and the uniform force enables the pump inner cylinder 10 to better slide up and down along the pump outer cylinder 7 under the action of tension.

[0027] In another preferred embodiment, a plurality of stabilizers 5 are provided between the outer surface of the pump rod 3 and the inner surface of the working tube 4, so that the pump rod 3 can be centered to the greatest extent without affecting the extraction of mid-deep seawater, thereby preventing shaking due to the long pump rod 3, thereby affecting the up and down sliding of the pump inner cylinder 10 in the pump outer cylinder 7.

[0028] In the wave-type carbon dioxide storage device of the present invention, preferably, two floating valves 8 are arranged from top to bottom in the pump inner cylinder 10. In actual application, when the pump inner cylinder 1 slides downward, the valve ball of the fixed valve 9 falls on its valve seat, and the middle-deep seawater no longer enters the area of ​​the working pipe 4 between the fixed valve 9 and the pump inner cylinder 10 through the fixed valve 9, while the middle-deep seawater that has entered before can enter the area of ​​the working pipe 4 above the pump inner cylinder 10 through the floating valve 8 because the valve ball of the floating valve 8 leaves its valve seat, and finally pumped out of the sea surface. Among them, since the waves make the buoy 1 move up and down along the buoy positioning frame 13 at a fast speed, when only one floating valve 8 is set in the pump inner tube 10, it is easy for part of the deep and medium seawater that has entered the working tube 4 in the area above the pump inner tube 10 to flow back, or the deep and medium seawater that has previously entered the working tube 4 in the area between the fixed valve 9 and the pump inner tube 10 cannot fully enter the working tube 4 in the area above the pump inner tube 10, resulting in low extraction efficiency of deep and medium seawater. In addition, when there are more than two floating valves 8 from top to bottom in the pump inner tube 10, for example, when three are set, in actual application, although it will not cause the deep and medium seawater that enters the working tube 4 in the area above the pump inner tube 10 to flow back, it will obviously affect the efficiency of the deep and medium seawater that has previously entered the working tube 4 in the area between the fixed valve 9 and the pump inner tube 10 to enter the working tube 4 in the area above the pump inner tube 10, thereby affecting the extraction efficiency of deep and medium seawater, and further affecting the dissolution efficiency of carbon dioxide. Therefore, two movable valves 8 are arranged from top to bottom in the pump inner tube 10 to effectively improve the extraction efficiency of deep and medium-depth seawater while avoiding backflow.

[0029] In the wave-type carbon dioxide storage device described in the present invention, the fixing member can be any optional component that can stably and effectively fix the working pipe 4. Specifically, for example, the fixing member is a fixing plate and / or an anchor chain 6, and several of the fixing plates are used to fix the working pipe 4 on the marine platform. One end of several of the anchor chains 6 is arranged around the working pipe 4 and connected to the seabed, and the other end is connected to the working pipe 4. More specifically, when implemented based on an offshore platform, the fixing member is preferably a fixing plate, so that based on the original stable structure of the offshore platform, the working pipe 4 can be stably fixed in the seabed; of course, the fixing plate and the anchor chain 6 can also be used at the same time to further stably fix the working pipe 4 in the seabed. When there is no offshore platform to rely on, the fixing member is preferably an anchor chain 6, so that one end of several of the anchor chains 6 is arranged around the working pipe 4 and connected to the seabed, and the other end is connected to the working pipe 4 at different heights at a set angle to achieve stable fixation of the working pipe 4.

[0030] In the wave-type carbon dioxide storage device described in the present invention, it is preferred that a level meter is also provided on the top of the buoy positioning frame 13, and the level meter includes a solar power supply module, a wireless transmission module and an alarm module, which is used to send an alarm message through the wireless transmission module and make an on-site alarm through the alarm module when the working pipe 4 deviates from the set angle in the vertical direction. In actual application, when the difference between the horizontal value detected by the level meter and the initial horizontal value is greater than the set threshold value, it can be regarded that the working pipe 4 has deviated from the set angle in the vertical direction. At this time, an alarm needs to be issued in time to remind relevant staff to reinforce the working pipe 4, so as to prevent the deviation angle of the working pipe 4 from further expanding, resulting in greater losses.

[0031] In the wave-type carbon dioxide storage device described in the present invention, preferably, a screen tube 12 is provided at the bottom of the working pipe 4 below the fixed valve 9, so as to filter impurities in the middle and deep seawater entering the working pipe 4 to avoid blockage and interruption of the extraction of the middle and deep seawater.

[0032] In the wave-type carbon dioxide storage device described in the present invention, preferably, one end of the working pipe 4 extending in the coastal plane direction is connected to the end of the buoy positioning frame 13 located below the sea level through the guide 2, thereby achieving a stable connection between the working pipe 4 and the buoy positioning frame 13 while discharging the middle and deep seawater to the seawater surface.

[0033] The present invention will be described in detail below through examples, but the protection scope of the present invention is not limited thereto.

[0034] Example 1

[0035] Use Figure 1 The wave-type carbon dioxide storage device shown is implemented based on an offshore platform. Specifically, the wave-type carbon dioxide storage device includes a working pipe 4 and a fixing part. One end of the working pipe 4 is inserted into the seabed in a vertical direction, and the other end extends in a coastal plane direction and is connected to an end of a buoy positioning frame 13 located below the sea level. The buoy 1 is arranged in the buoy positioning frame 13, and its bottom is connected to a pump inner cylinder 10 slidably arranged in a pump outer cylinder 7 of the working pipe 4 through a pump rod 3. A sealing ring 11 is arranged between the outer side of the pump inner cylinder 10 and the inner side of the pump outer cylinder 7. A floating valve 8 is arranged in the pump inner cylinder 10. A fixed valve 9 is arranged inside the working pipe 4 located below the pump outer cylinder 7. The fixing part is used to fix the working pipe 4 in the seabed.

[0036] Specifically, the diameter of the buoy positioning frame 13 is larger than the diameter of the buoy 1, and the difference between the two is 3 cm; the buoy 1 is provided with an upflow hole with a gradually decreasing diameter extending from the middle of the bottom to the top; one end of the pump rod 3 is connected to the bottom of the upflow hole of the buoy 1, and the other end is connected to the middle of the top of the pump inner tube 10; a plurality of stabilizers 5 are sleeved between the outer surface of the pump rod 3 and the inner surface of the working pipe 4; two floating valves 8 are arranged in the pump inner tube 10 from top to bottom; the fixing parts are fixing plates and anchor chains 6, and a plurality of the fixing plates are used to fix the working pipe 4 on the marine platform, and one end of a plurality of the anchor chains 6 is arranged around the working pipe 4 and connected to the seabed, and the other end is connected to the working pipe 4; a screen tube 12 is provided at the bottom of the working pipe 4 below the fixed valve 9; the end of the working pipe 4 extending in the coastal plane direction is connected to the end of the buoy positioning frame 13 located below the sea level through a guide 2.

[0037] In actual application, the working pipe 4 is firstly fixed vertically by the fixing plate and the anchor chain 6, and then when the sea waves enter the buoy positioning frame 13, the buoy 1 moves up and down along the inside of the buoy positioning frame 13 under the vertical guidance of the buoy positioning frame 13 and the drive of the waves, thereby driving the pump rod 3 connected thereto to move up and down, and then driving the pump inner cylinder 10 to slide up and down along the inside of the pump outer cylinder 7, wherein a sealing ring 11 is provided between the pump inner cylinder 10 and the pump outer cylinder 7, and at the same time, the valve balls of the two swimming valves 8 sit on the valve seats under the action of gravity, forming a piston effect between the pump inner cylinder 10 and the pump outer cylinder 7; specifically, when the sea waves drive the buoy 1 to move upward along the buoy positioning frame 13, due to the piston action, The pressure at the lower part of the pump inner cylinder 10 is reduced, and the valve ball on the fixed valve 9 leaves the valve seat due to the suction, and seawater flows in through the screen tube 12 and enters the pump outer cylinder 7 through the fixed valve 9; and when the sea water waves drive the buoy 1 to move downward along the buoy positioning frame 13, the valve ball of the fixed valve 9 sits on the valve seat due to gravity. At the same time, due to the action of the sealing ring 11 between the pump inner cylinder 10 and the pump outer cylinder 7, a piston effect is formed between the pump inner cylinder 10 and the pump outer cylinder 7, and the valve balls of the two swimming valves 8 leave the valve seat due to the water pressure, and the seawater between the fixed valve 9 and the pump inner cylinder 10 enters the upper part of the pump inner cylinder 10, and the reciprocating motion is repeated, so as to realize the continuous extraction of the middle and deep seawater and discharge it to the ocean surface through the guide 2.

[0038] After testing, it is found that the wave-type carbon dioxide storage device described in the present invention, compared with the carbon dioxide storage device based on self-powered equipment in the prior art, can sustainably and stably extract middle and deep seawater to the ocean surface for dissolving carbon dioxide in actual application, and has the advantages of good economy, stability and reliability.

[0039] Example 2

[0040] The embodiment 1 is implemented with reference to the embodiment 1, but differs therefrom in that it further includes a spirit level arranged on the top of the buoy positioning frame 13, and the spirit level includes a solar power supply module, a wireless transmission module and an alarm module, which is used to send an alarm message through the wireless transmission module and make an on-site alarm through the alarm module when the working tube 4 deviates from the set angle in the vertical direction.

[0041] After testing, it is found that the wave-type carbon dioxide storage device described in the present invention, compared with the carbon dioxide storage device based on self-powered equipment in the prior art, can sustainably and stably extract medium and deep seawater to the ocean surface for dissolving carbon dioxide in actual application, and has the advantages of good economy, stability and reliability. At the same time, it can also further effectively improve the safety and reliability of the carbon dioxide storage device.

[0042] In actual application, the wave-type carbon dioxide storage device provided by the present invention is to insert the working pipe into the seabed and fix it under the action of the fixing parts, and the buoy drives the pump inner cylinder to move up and down in the pump outer cylinder through the pump rod under the drive of the waves and the vertical limit of the buoy positioning frame, forming a piston effect, thereby continuously pumping the middle and deep seawater out of the sea surface for dissolving carbon dioxide, which has the advantages of good economy, stability and reliability.

[0043] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
