Description

Technical Field

[0001] The present invention relates to a carbon dioxide collection device.

Background Art

[0002] It is to be clarified that the content described in this part merely provides background information for the present invention and does not constitute prior art.

[0003] In accordance with the international maritime greenhouse gas emission reduction target, the amount of carbon dioxide emitted when one ton of cargo is transported one mile is restricted.

[0004] In order to suppress the carbon dioxide emissions of ships, various methods such as improving energy efficiency, fuel conversion, and developing carbon dioxide collection technology in ships are being tried.

[0005] In the carbon dioxide (CO2) collection technology for ships, as the scale of the collection process increases, the amount of cargo that can be loaded decreases. Therefore, it is very important to reduce the size of the carbon dioxide collection device.

[0006] In addition, when the carbon dioxide collection device is installed on a ship or the like where fluid flow occurs, the carbon dioxide collection device may flow due to the fluid flow of the ship. As a result, the exhaust gas and liquid inside the carbon dioxide collection device may also flow, which may reduce the carbon dioxide collection performance.

[0007] Particularly, in the example where the carbon dioxide collection device is installed in a high-column type, since the liquid and gas flow inside the high column according to the fluid flow of the ship, channeling occurs inside the high column, and the carbon dioxide collection performance decreases.

[0008] For example, a study by Ros et al. (2022) found that when the tall column was tilted 5° from the vertical (semi-tilted), the carbon dioxide capture efficiency decreased by 7% compared to when the tall column was not tilted (straight), and when the tall column was tilted 10° from the vertical (full tilted), the carbon dioxide capture efficiency decreased by approximately 19% compared to when the tall column was not tilted (straight).

[0009] Therefore, there is a need to develop a carbon dioxide capture device that can reduce the size of the device and overcome the reduction in carbon dioxide capture performance caused by factors such as ship movement. [Prior art documents] [Patent Documents]

The scope of the rights of the present invention is determined by the matters described in the claims and matters that can be reasonably inferred therefrom.

[0040] Figure 1 shows a comparative example of carbon dioxide collection device 1.

[0041] Referring to Figure 1, the comparative example carbon dioxide collection device 1 may include a carbon dioxide collection device 1 that collects carbon dioxide contained in exhaust gas G, and a decarbonation tower 2 that separates carbon dioxide from the liquid L that has moved from the carbon dioxide collection device 1.

[0042] However, the comparative example carbon dioxide collection device 1 has a significantly increased height compared to the carbon dioxide collection device 10 according to one embodiment of the present invention, which has the problem of not being able to efficiently utilize space.

[0043] One embodiment of the present invention aims to overcome the shortcomings of the comparative example carbon dioxide collection device 1 by reducing the size of the carbon dioxide collection device 10 and efficiently utilizing space, thereby improving the carbon dioxide collection efficiency.

[0044] In the following, with reference to Figures 2 and 3, the components included in the carbon dioxide collection device 10 according to one embodiment of the present invention will be specifically described.

[0045] Figure 2 is a perspective view showing some of the components included in the carbon dioxide collection device 10 according to one embodiment of the present invention. Figure 3 is a cross-sectional view of the carbon dioxide collection device 10 according to one embodiment of the present invention.

[0046] A carbon dioxide collection device 10 according to one embodiment of the present invention may include a chamber unit 100, a rotor unit 200, and a rotating unit 300.

[0047] The chamber unit 100 has an internal containment space 130 through which exhaust gas G containing carbon dioxide and liquid L that reacts with the exhaust gas G can flow in and out.

[0048] The exhaust gas G can be supplied to the containment space 130 via the gas inlet pipe 111. The exhaust gas G can move through the flow channel structure 230 due to the supply pressure of the exhaust gas G. As a result, the liquid L and the exhaust gas G intersect in the multiple flow channels of the flow channel structure 230, and the carbon dioxide contained in the exhaust gas G can be captured in the liquid L.

[0049] The rotor unit 200 is rotatably installed in the housing space 130 and may have an intersection space 210 where the liquid L and exhaust gas G intersect.

[0050] In the intersecting space 210, the liquid L and the exhaust gas G intersect with each other, allowing the liquid L to capture carbon dioxide from the exhaust gas G.

[0051] The rotor unit 200 can rotate around its central axis X. Centrifugal force acts on the rotor unit 200, and centrifugal force can also act on the flow channel structure 230 of the rotor unit 200.

[0052] When the rotor unit 200 rotates, the liquid L can move outward in the circumferential direction of the rotational axis X through the flow channel structure 230 due to centrifugal force. The exhaust gas G can move inward in the circumferential direction of the rotational axis X through the flow channel structure 230 due to the supply pressure of the exhaust gas G.

[0053] Therefore, the liquid L and the exhaust gas G can intersect in the flow path structure 230 while moving in opposite directions, and the carbon dioxide contained in the exhaust gas G can be captured and moved by the liquid L.

[0054] Liquid L and exhaust gas G can each pass through the flow path structure 230. Liquid L can move away from the rotation axis X, and exhaust gas G can move towards the rotation axis X.

[0055] Liquid L and exhaust gas G react upon contact, and liquid L can capture carbon dioxide contained in exhaust gas G. Because liquid L and exhaust gas G react upon contact, the carbon dioxide capture efficiency can be improved when the contact area between the two is maximized.

[0056] The carbon dioxide collection performance may vary depending on factors such as the supply speed of exhaust gas G and liquid L, and the rotation speed of the rotor unit 200.

[0057] The rotating unit 300 can rotate the rotor unit 200.

[0058] For example, the rotating unit 300 can rotate the rotor unit 200, which is located inside the chamber unit 100, when it is installed on one side of the chamber unit 100.

[0059] The rotor unit 200 may have a flow channel structure 230 that forms multiple flow channels in the intersecting space 210. The liquid L and exhaust gas G can intersect with each other while moving through the multiple flow channels.

[0060] The flow channel structure 230 is installed across the intersecting space 210 and can be configured in a cylindrical ring shape. The space in the cylindrical ring shape may be filled with the flow channel structure 230.

[0061] A multi-channel system may also consist of multiple channels through which liquid L and exhaust gas G move.

[0062] As an example, a multi-channel flow system may have multiple channels formed between the gaps in a mesh-like channel structure 230. As another example, a multi-channel flow system may have multiple channel pins 230-2 installed at intervals, with multiple channels formed between the spaced-apart channel pins 230-2 through which liquid L and exhaust gas G move. This will be explained in more detail later.

[0063] For example, the carbon dioxide capture device 10 of the present invention may be installed on a ship.

[0064] The carbon dioxide collection device 10 of the present invention can improve the carbon dioxide collection efficiency by maximizing the contact area between the liquid L and the exhaust gas G, as the flow channel structure 230 forms multiple flow channels in the intersecting space 210.

[0065] The carbon dioxide collection device 10 of the present invention is configured such that the rotor unit 200 rotates and the exhaust gas G and liquid L intersect with each other to collect carbon dioxide, thereby significantly increasing the rate of mass transfer and improving the carbon dioxide collection efficiency.

[0066] By reducing the size of the carbon dioxide collection device 10 of the present invention, it is possible to efficiently utilize space in ships and other vessels with limited space and to improve the carbon dioxide collection efficiency.

[0067] The flow channel structure 230 can be installed so as to occupy a ring-shaped space in the intersecting space 210.

[0068] The liquid L can move from the first side surface 230-1a on the inner diameter side of the flow channel structure 230 toward the second side surface 230-1b on the outer diameter side of the flow channel structure 230 due to the centrifugal force acting on the rotor unit 200. The exhaust gas G can move from the second side surface 230-1b toward the first side surface 230-1a due to the supply pressure of the exhaust gas G.

[0069] The exhaust gas G can leave the flow path structure 230 while passing through the first side surface 230-1a and move through the space below the liquid distribution chamber 170, which will be described later. It can then be discharged to the outside of the carbon dioxide capture device 10 via the gas discharge pipe 112.

[0070] The first side surface 230-1a is the inner diameter side surface of the ring-shaped flow channel structure 230, and the second side surface 230-1b is the outer diameter side surface of the ring-shaped flow channel structure 230.

[0071] When the rotor unit 200 rotates, centrifugal force can act on the flow channel structure 230. As the rotor unit 200 rotates, the liquid L can move circumferentially outward through the flow channel structure 230 due to the centrifugal force. Specifically, the liquid L can move toward the first side surface 230-1a of the flow channel structure 230. The liquid L can flow in through the first side surface 230-1a of the flow channel structure 230, pass through the interior of the flow channel structure 230, and be discharged through the second side surface 230-1b of the flow channel structure 230.

[0072] The chamber unit 100 may include a chamber body 110 and a liquid distribution chamber 170.

[0073] The chamber body 110 may have an internal storage space 130.

[0074] The chamber body 110 may be equipped with a gas inlet pipe 111, a gas outlet pipe 112, a liquid inlet pipe 113, and a liquid outlet pipe 114.

[0075] Exhaust gas G containing carbon dioxide can flow into the gas inlet pipe 111. The gas outlet pipe 112 allows the incoming exhaust gas G to be discharged via the rotor unit 200. For example, the gas inlet pipe 111 may be located on one side of the chamber unit 100, and the gas outlet pipe 112 may be located on the upper side of the chamber unit 100.

[0076] Liquid L, which reacts with exhaust gas G, can flow into the liquid inlet pipe 113. The liquid discharge pipe 114 allows the incoming liquid L to be discharged via the rotor unit 200. For example, the liquid inlet pipe 113 may be located above the chamber unit 100, and the liquid discharge pipe 114 may be located below the chamber unit 100.

[0077] The liquid distribution chamber 170 is fixed to the chamber body 110 and can distribute liquid L toward the flow channel structure 230.

[0078] The liquid distribution chamber 170 can be placed in the containment space 130, and the liquid distribution chamber 170 is a fixed component that does not rotate.

[0079] The liquid distribution chamber 170 is positioned around the first side surface 230-1a of the flow channel structure 230, and can distribute the liquid L toward the first side surface 230-1a of the flow channel structure 230.

[0080] With respect to the rotational axis X, a flow channel structure 230 is positioned outside the liquid distribution chamber 170, and the liquid L distributed from the liquid distribution chamber 170 can be discharged through the flow channel structure 230 to the containment space 130 outside the flow channel structure 230.

[0081] When the rotor unit 200 rotates, centrifugal force can act on the flow channel structure 230 of the rotor unit 200. The discharged liquid L can move toward the flow channel structure 230 while being pulled by the centrifugal force acting on the flow channel structure 230.

[0082] The liquid L discharged from the liquid distribution chamber 170 can move to the containment space 130 of the chamber unit 100 via the flow channel structure 230 installed in the crossing space 210.

[0083] The liquid distribution chamber 170 may be positioned at a distance from the inner surface of the lower chamber body 110. The exhaust gas G can exit the flow path structure 230 by passing through the first side surface 230-1a of the flow path structure 230. It can then move to the gas discharge pipe 112 via the space below the liquid distribution chamber 170 and be discharged to the outside of the carbon dioxide capture device 10.

[0084] The liquid distribution chamber 170 may include a cylindrical ring chamber 171 and a disassembly port.

[0085] The cylindrical ring chamber 171 is configured in a cylindrical ring shape and is positioned around the first side surface 230-1a on the inner diameter side of the flow channel structure 230, allowing the liquid L to be distributed toward the flow channel structure 230.

[0086] The upper part of the cylindrical ring chamber 171 can communicate with the liquid storage chamber 150. The cylindrical ring chamber 171 can receive a supply of liquid L at a constant pressure from the liquid storage chamber 150, which will be described later.

[0087] The distribution hole 173 is formed through the cylindrical ring chamber 171 and can form a path for distributing liquid L toward the first side surface 230-1a.

[0088] The distribution holes 173 can be positioned in the direction of the flow channel structure 230. Liquid L can move from the cylindrical ring chamber 171 towards the flow channel structure 230 through the distribution holes 173. If the flow channel structure 230 is cylindrical ring-shaped, multiple distribution holes 173 may be arranged spaced apart along the circumferential and height directions of the cylindrical ring shape.

[0089] The liquid L discharged from the distribution hole 173 can move toward the first side surface 230-1a of the flow channel structure 230, pulled by the centrifugal force acting on the flow channel structure 230. Subsequently, the liquid L can flow in through the first side surface 230-1a of the flow channel structure 230, pass through the interior of the flow channel structure 230, and be discharged into the containment space 130 of the chamber body 110 via the second side surface 230-1b of the flow channel structure 230.

[0090] The chamber unit 100 may further include a liquid storage chamber 150.

[0091] The liquid storage chamber 150 is located on one side of the chamber body 110 and can supply the stored liquid L to the liquid distribution chamber 170. The liquid storage chamber 150 stores the liquid L that flows in through the liquid inlet pipe 113 and is connected to the liquid distribution chamber 170 so that the liquid L can be supplied to the liquid distribution chamber 170. The liquid storage chamber 150 can serve the role of supplying the stored liquid L to the liquid distribution chamber 170 at a constant pressure.

[0092] The liquid storage chamber 150 is positioned above the liquid (L) distribution chamber, and the liquid storage chamber 150 can have a larger liquid (L) storage space than the liquid distribution chamber 170. As a result, the liquid storage chamber 150 can supply the stored liquid L to the liquid distribution chamber 170 at a constant pressure.

[0093] For example, the liquid storage chamber 150 may be located above the chamber body 110, or it may be positioned to surround the gas discharge pipe 112.

[0094] Figure 4 shows a detailed view of section "A" in Figure 3.

[0095] Referring to Figure 4, the flow channel structure 230 may include a mesh structure 230-1 that is formed in a network-like manner.

[0096] As an example, the flow channel structure 230 may be composed of a mesh structure 230-1. In the mesh structure 230-1, multiple flow channels may be formed in which the liquid L and exhaust gas G intersect with each other. Specifically, multiple flow channels in which the exhaust gas G and liquid L move can be formed between the mesh structure of the mesh structure 230-1.

[0097] Referring to Figure 4, the flow channel structure 230 can include an upper rotor plate 233, a lower rotor plate 235, and a mesh structure 230-1.

[0098] The upper rotor plate 233 may be positioned above the crossing space 210 and installed so as to close off the upper side of the crossing space 210.

[0099] A sealing member S may be placed between the chamber body 110 and the upper rotor plate 233. The sealing member S can prevent exhaust gas G from moving between the chamber body 110 and the upper rotor plate 233. The sealing member S may be configured in a ring shape.

[0100] For example, the sealing member S may be fixed to the chamber body 110, or it may be separated from the rotor unit 200. That is, the upper rotor plate 233 of the rotor unit 200 is positioned close to the sealing member S, blocking the movement of exhaust gas G, and the rotor unit 200 can rotate in close proximity to the sealing member S.

[0101] The lower rotor plate 235 can be separated from the upper rotor plate 233 in the height direction. The lower rotor plate 235 may be positioned below the crossing space 210 and installed so as to close off the lower side of the crossing space 210.

[0102] The first drive shaft 310 of the rotary unit 300 can be fixed to the lower rotor plate 235, and when the first rotary drive member 330 rotates the first drive shaft 310, the rotor unit 200 can rotate while the lower rotor plate 235 fixed to the first drive shaft 310 rotates together with it.

[0103] An intersecting space 210 may be placed between the upper rotor plate 233 and the lower rotor plate 235, and a mesh structure 230-1 may be placed in the intersecting space 210.

[0104] The mesh structure 230-1 is installed between the upper rotor plate 233 and the lower rotor plate 235, is formed in a mesh-like manner, and can be installed to occupy a ring-shaped space in the intersection space 210.

[0105] Since the mesh structure 230-1 is formed in a mesh-like manner, exhaust gas G and liquid L can move through the mesh structure 230-1.

[0106] The mesh structure 230-1 may be installed such that the mesh structure fills a ring-shaped space.

[0107] For example, the mesh structure 230-1 may be closed at the top by the upper rotor plate 233 and closed at the bottom by the lower rotor plate 235. Thus, the exhaust gas G and liquid L can move into the mesh structure 230-1 via the first side surface 230-1a and the second side surface 230-1b, or move to the outside of the mesh structure 230-1.

[0108] As an example, a ring-shaped mesh structure 230-1 may be integrally installed in the intersecting space 210.

[0109] The mesh structure 230-1 can be constructed as a single unit in which a mesh structure is filled into a ring-shaped space. For example, the mesh structure 230-1 may be manufactured as a single unit in the shape of a cylindrical ring.

[0110] Figure 5 shows a part of the carbon dioxide collection device 10 according to another embodiment of the present invention that corresponds to part "A" in Figure 3.

[0111] Referring to Figure 5, the mesh structure 230-1 can be formed by winding up a mesh ribbon 230-1c and filling it into a ring-shaped space.

[0112] Figure 6 shows a part of a carbon dioxide collection device 10 according to yet another embodiment of the present invention, corresponding to part "A" in Figure 3.

[0113] The flow channel structure 230 may have multiple flow channel pins 230-2 arranged at intervals, and multiple flow channels may be formed between the multiple flow channel pins 230-2. Multiple flow channels can be formed between the multiple flow channel pins 230-2 where the liquid L and exhaust gas G intersect.

[0114] The rotor unit 200 may include an upper rotor plate 233, a lower rotor plate 235, and a plurality of flow path pins 230-2.

[0115] Since the upper rotor plate 233 and the lower rotor plate 235 have already been explained in relation to Figure 4, we will omit their explanation to avoid repetition and will focus on explaining aspects that differ from those explained in Figure 4.

[0116] The flow path pins 230-2 are fixed to at least one of the upper rotor plate 233 and the lower rotor plate 235, and multiple pins can be arranged spaced apart in the intersecting space 210.

[0117] The flow path pin 230-2 can extend vertically. For example, the flow path pin 230-2 may be installed to connect the upper rotor plate 233 and the lower rotor plate 235. One end of the flow path pin 230-2 can be fixed to the upper rotor plate 233, and the other end of the flow path pin 230-2 can be fixed to the lower rotor plate 235. For example, the flow path pin 230-2 may be a cylindrical pin with a length in the height direction that is longer than its diameter.

[0118] As another example, one end of the flow path pin 230-2 may be fixed to at least one of the upper rotor plate 233 and the lower rotor plate 235.

[0119] Figure 7 is a perspective view of a carbon dioxide collection device 10 according to another embodiment of the present invention. Figure 8 is a perspective view of a carbon dioxide collection device 10 according to yet another embodiment of the present invention.

[0120] Referring to Figures 7 and 8, the carbon dioxide collection device 10 may further include an elastic unit 400.

[0121] The elastic unit 400 is installed on the chamber unit 100 and can elastically support the chamber unit 100. For example, the elastic unit 400 may consist of spring members that support the chamber unit 100. Multiple spring members may be installed to support the lower side of the chamber unit 100.

[0128] For example, the sealing member S may be fixed to the lower rotor plate 235, or the sealing member S may be separated from the first drive shaft 310. That is, the lower rotor plate 235 of the rotor unit 200 is positioned close to the sealing member S, blocking the movement of exhaust gas G, and the first drive shaft 310 can rotate in close proximity to the sealing member S.

[0129] The first rotational drive member 330 is installed on one side of the chamber unit 100 and can rotate the rotor unit 200 by rotating the first drive shaft 310.

[0137] If the installation space in which the carbon dioxide capture device 10 is installed is long in the vertical direction, it may be advantageous in terms of efficient use of the installation space if the rotational axis X of the rotor unit 200 is formed to extend in the vertical direction.

[0138] Figure 9 is a perspective view of a carbon dioxide collection device 10 according to yet another embodiment of the present invention. Figure 10 is a cross-sectional view of a carbon dioxide collection device 10 according to yet another embodiment of the invention.

[0140] If the installation space for the carbon dioxide capture device 10 is long in the horizontal direction, it may be advantageous in terms of efficient use of the installation space if the rotational axis X of the rotor unit 200 is formed to extend in the horizontal direction.

[0141] Exhaust gas G containing carbon dioxide can flow into the gas inlet pipe 111. The gas outlet pipe 112 allows the incoming exhaust gas G to be discharged via the rotor unit 200. For example, the gas inlet pipe 111 may be located on one side of the chamber unit 100, and the gas outlet pipe 112 may be located on the other side of the chamber unit 100.

[0142] Liquid L, which reacts with exhaust gas G, can flow into the liquid inlet pipe 113. The liquid discharge pipe 114 allows the incoming liquid L to be discharged via the rotor unit 200.

[0143] In the following, with reference to Figures 11 and 12, the carbon dioxide collection device 10 of the comparative example will be compared in more detail with the carbon dioxide collection device 10 according to one embodiment of the present invention.

[0144] Figure 11 is a perspective view showing a ship equipped with the comparative example carbon dioxide collection device 1 (hereinafter referred to as the "comparative example") of Figure 1. Figure 12 is a perspective view showing a ship T equipped with the carbon dioxide collection device 10 (hereinafter referred to as the "present invention") according to one embodiment of the present invention.

[0145] Table 1 below shows information on gases emitted from a vessel with an output of 3,000 kW.

[0146] [Table 1]

[0147] Since a cargo ship (ship T) only generates exhaust gases during operation, the actual amount of exhaust gas G emitted when ship T is in operation is approximately 10-25% of the theoretical total flow rate. However, the calculation was performed using the maximum emission rate of the ship (based on 100% load). When the carbon dioxide capture and removal rate of the cargo ship was set at 90%, the amount of carbon dioxide captured was approximately 25.3 TPD (tons / day). Table 2 below shows a comparison between the comparative example and the present invention for a ship with an output of 3,000 kW.

[0148] [Table 2]

[0149] Here, the diameter of the carbon dioxide collection device 10 of the present invention, which is 1.5 m, includes the gas outlet of 0.3 m, and the actual diameter of the carbon dioxide collection device 10 was 1.2 m. The diameter of the desorption tower 20 of the present invention, which is 1.0 m, includes the gas outlet of 0.3 m, and the actual diameter of the carbon dioxide collection device 10 was 0.7 m. Compared to the comparative example of the present invention, the volume of the carbon dioxide collection device was reduced by approximately 73.0%, and the volume of the desorption tower was reduced by 64.1% compared to the comparative example of the present invention.

[0150] Thus, it has been found that the present invention occupies a much smaller space than the comparative example, enabling efficient use of space in limited spaces such as ships.

[0151] Although embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and it will be obvious to those with ordinary skill in the art that various modifications and variations are possible without departing from the technical idea of ​​the present invention as described in the claims.
