Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, a recovery device as described in Patent Document 1 includes various devices such as a cooling tower that cools exhaust gas, an absorption tower that captures carbon dioxide contained in the exhaust gas with an absorption liquid, and a regeneration tower that separates carbon dioxide from the absorption liquid that has absorbed carbon dioxide. When attempting to recover carbon dioxide from the exhaust gas generated on a ship, such various devices become large-sized. Along with this, the entire recovery device also becomes large-sized. In a container ship that transports containers, the exposed deck is a container space for loading a plurality of containers. Therefore, if a recovery device is installed on the exposed deck, the container loading space becomes smaller, and the number of containers that can be loaded decreases.

[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide a container ship that can be equipped with carbon dioxide recovery equipment while suppressing a decrease in the container loading capacity.

[0006] To solve the above problems, the container ship according to this disclosure comprises a hull, an engine room, an engine casing, and a carbon dioxide recovery unit. The hull has an exposed deck which serves as a container space capable of loading multiple containers. The engine room is located inside the hull and houses a combustion device for burning fuel. The engine casing communicates with the upper part of the engine room and protrudes above the exposed deck. The engine casing houses an exhaust pipe through which exhaust gas from the combustion device flows. The carbon dioxide recovery unit comprises a casing and several types of equipment. The casing is positioned adjacent to the engine casing in the bow-stern direction and is provided to protrude above the exposed deck. The several types of equipment are arranged inside the casing. The several types of equipment are for recovering carbon dioxide from exhaust gas supplied through the exhaust pipe inside the engine casing. [Effects of the Invention]

[0007] According to the container ship described herein, it is possible to equip it with carbon dioxide capture equipment while minimizing the reduction in container load capacity. [Brief explanation of the drawing]

[0008] [Figure 1] This is a side view of a container ship according to an embodiment of the present disclosure. [Figure 2] This is a cross-sectional view of a carbon dioxide capture unit according to the embodiment of this disclosure, as seen from the bow-stern direction. [Figure 3] This is a cross-sectional view of a carbon dioxide capture unit according to a modified embodiment of the present disclosure, as seen from the bow-stern direction. [Modes for carrying out the invention]

[0009] Hereinafter, a container ship according to the embodiment of this disclosure will be described with reference to Figures 1 to 3. (Container ship configuration) As shown in Figure 1, the container ship 1 of the embodiment of the present disclosure comprises at least a hull 2, a superstructure 4, a combustion device 8, and a carbon dioxide capture unit 20.

[0010] (hull) The hull 2 ​​has a pair of side plates 5A and 5B that form its outer shell, and a bottom 6. The side plates 5A and 5B are each provided with a pair of side plates that form the port and starboard sides, respectively. The bottom 6 is provided with bottom plates that connect these side plates 5A and 5B. Together with these pair of side plates 5A and 5B and the bottom 6, the outer shell of the hull 2 ​​has a U-shape in a cross section perpendicular to the bow-stern direction FA.

[0011] The hull 2 ​​further includes an exposed deck 7, which is a full-length deck located at the uppermost level. The superstructure 4 is formed on this exposed deck 7. Living quarters and the like are provided within the superstructure 4. In this embodiment of the container ship 1, the exposed deck 7 serves as a container space S capable of loading multiple rectangular containers 100.

[0012] (Combustion device) The combustion device 8 is a device that generates thermal energy by burning fuel and is housed in the engine room 3. The engine room 3 is located inside the hull 2. Examples of combustion devices 8 include internal combustion engines used as the main engines for propelling the container ship 1, internal combustion engines used in power generation equipment that supplies electricity to the ship, and boilers that generate steam as a working fluid.

[0013] (Engine casing) An engine casing 9 is provided on the exposed deck 7. The engine casing 9 communicates with the upper part of the engine room 3 and protrudes above the exposed deck 7. Inside the engine casing 9 is an exhaust gas pipe 91 through which exhaust gas from the combustion device 8 flows.

[0014] (Configuration of the carbon dioxide capture unit) Figure 2 is a cross-sectional view of a carbon dioxide capture unit according to the present disclosure, as seen from the bow-stern direction. The carbon dioxide recovery unit 20 recovers carbon dioxide from the exhaust gas of the combustion device 8. As shown in Figure 2, the carbon dioxide recovery unit 20 includes several types of equipment 30 for recovering carbon dioxide from the exhaust gas supplied via the exhaust gas pipe 91 (see Figure 1), and a casing 40.

[0015] The multiple types of equipment 30 include tower-shaped equipment 31 extending in the vertical direction Dv. Examples of tower-shaped equipment 31 include an exhaust gas cooling tower 31C, an absorption tower 31B, a regeneration tower 31D, and an exhaust gas scrubbing tower 31A. Furthermore, if the combustion device 8 is a heavy oil-fired type that uses heavy oil as fuel, the exhaust gas from the combustion device 8 will contain impurities other than sulfur oxides (SOx) and carbon dioxide, such as soot. For this reason, before the exhaust gas from the combustion device 8 is sent to a cooling tower to cool the exhaust gas, several types of equipment 30 may be installed, such as a scrubber 32 to recover sulfur oxides contained in the exhaust gas from the combustion device 8, and an electrostatic precipitator 33 to recover impurities. The arrangement and size of the various types of equipment 30 shown in Figure 2 are merely examples and can be changed as appropriate.

[0016] The exhaust gas cooling tower 31C is connected to the exhaust gas pipe 91 inside the engine casing 9 via piping 35 (see Figure 1). The exhaust gas cooling tower 31C cools the exhaust gas from the combustion device 8 (see Figure 1), which is introduced via piping 35, using the surrounding water on which the hull 2 ​​floats, or fresh water stored in a fresh water tank (not shown) located inside the hull 2, as a coolant.

[0017] The absorption tower 31B captures carbon dioxide contained in the exhaust gas that has passed through the exhaust gas cooling tower 31C into the absorbent liquid. The absorption tower 31B captures carbon dioxide contained in the exhaust gas into the absorbent liquid by, for example, bringing the absorbent liquid into contact with the exhaust gas introduced into the absorption tower 31B. The absorption tower 31B absorbs carbon dioxide contained in the exhaust gas into the absorbent liquid by, for example, a chemical absorption method. In this embodiment, MEA (monoethanolamine) is used as the absorbent liquid for chemical absorption of carbon dioxide. Other materials can also be used as the absorbent liquid.

[0018] The exhaust gas scrubbing tower 31A allows the scrubbing liquid to fall from the upper part inside the exhaust gas scrubbing tower 31A to wash away the absorption liquid contained in the exhaust gas exiting the absorption tower 31B. As the scrubbing liquid, for example, water around the floating hull 2 or fresh water stored in a fresh water tank (not shown) provided inside the hull 2 is used.

[0019] The regeneration tower 31D separates gaseous carbon dioxide from the absorption liquid that has absorbed carbon dioxide in the absorption tower 31B. The regeneration tower 31D separates gaseous carbon dioxide from the absorption liquid by heating the absorption liquid sent from the absorption tower 31B into the regeneration tower 31D.

[0020] Examples of the multiple types of equipment 30 provided in the carbon dioxide recovery unit 20 include pipes connecting these tower-shaped devices 31 to each other, pumps, heat exchangers, etc., in addition to the exhaust gas cooling tower 31C, the absorption tower 31B, the regeneration tower 31D, and the exhaust gas scrubbing tower 31A.

[0021] (Casing) The casing 40 forms the outer shell of the carbon dioxide recovery unit 20. The casing 40 guides the exhaust gas from the exhaust gas pipe 91 into the carbon dioxide recovery unit 20. The casing 40 has a wall portion 41, a ceiling portion 42, and a bottom plate portion 43. The casing 40 may be provided with a single or multiple intermediate decks 45 between the ceiling portion 42 and the bottom plate portion 43. The wall portion 41, the ceiling portion 42, the bottom plate portion 43, and the intermediate deck 45 are formed of steel plates similar to the engine casing 9 and have a predetermined strength by means of reinforcing materials (not shown) and columns 46 described later.

[0022] The wall portion 41 is formed so as to surround the entire circumference around the multiple types of equipment 30. The wall portion 41 is formed, for example, in a rectangular shape with the ship width direction W as the long side and the ship head and tail direction FA as the short side when viewed from the vertical direction Dv. The wall portion 41 is provided at a position that overlaps (in other words, is continuous) with a wall portion (not shown) provided inside the hull 2 when viewed from the vertical direction Dv. Note that the casing 40 may be arranged at a position that does not overlap with the engine room 3 in the ship head and tail direction FA. The wall-like section within the hull 2 ​​may be provided with a reinforcing member (not shown) that receives a portion of the load from the wall-like section 41.

[0023] The ceiling section 42 covers the upper end opening of the wall-like section 41 from above. The bottom plate section 43 constitutes part of the deck of the hull 2.

[0024] (Intermediate deck) The intermediate decks 45 are arranged in multiple layers within the casing 40, spaced apart in the vertical direction Dv. Each layer of the intermediate deck 45 is made of steel plate extending along the horizontal plane. Each layer of the intermediate deck 45 is joined to the inner circumferential surface of the wall-like section 41 and to the outer circumferential surface of the tower-like equipment 31 by welding. In this way, each tower-like equipment 31 is integrally connected to the casing 40 via the intermediate decks 45 arranged in multiple layers in the vertical direction Dv. Note that the intermediate decks 45 are not limited to steel plates; steel materials extending in the horizontal direction may also be used.

[0025] The intermediate deck 45 is supported by columns 46 extending in the vertical direction Dv. The upper and lower ends of the columns 46 are connected to the upper and lower intermediate decks 45 by welding, bolting, etc. Columns 46 are also similarly provided between the uppermost intermediate deck 45 and the ceiling 42, and between the lowermost intermediate deck 45 and the bottom plate 43.

[0026] For example, the columns 46 are made of steel that extends in the vertical direction Dv. It is preferable that adjacent columns 46 in the vertical direction Dv, with the intermediate deck 45 of each layer in between, are positioned so as to overlap when viewed from the vertical direction Dv. The columns 46 in this embodiment include steel materials referred to as so-called large bones. Of the columns 46, the steel materials referred to as large bones are fixed to the wall-like portion 41 by welding or the like and are formed along the wall-like portion 41. In addition, the ceiling portion 42 may be provided with large bones extending in the bow-stern direction FA and large bones extending in the width direction W in a grid pattern, and the large bones of the ceiling portion 42 may be connected to the upper ends of the large bones that serve as columns 46.

[0027] In the carbon dioxide capture unit 20 of this embodiment, multiple types of equipment 30 are firmly integrated by welding to the wall-like portion 41 of the casing 40 or the intermediate deck 45. This allows for a simplified support structure for supporting heavy objects such as the tower-like equipment 31. Such a carbon dioxide capture unit 20 may be pre-assembled outside the ship and then mounted onto the hull 2. This shortens the construction period required to install the carbon dioxide capture unit 20. Furthermore, by welding multiple types of equipment 30 to the wall-like portion 41 and intermediate deck 45 of the casing 40, the stress caused by the loads of the multiple types of equipment 30 can be distributed to the bottom of the casing 40. This reduces stress concentration at the base of the casing 40.

[0028] In this embodiment, the casing 40 of the carbon dioxide recovery unit 20 is positioned adjacent to the engine casing 9 in the bow-stern direction FA in order to guide exhaust gas from the exhaust gas pipe 91 to the carbon dioxide recovery unit 20. In this case, a part of the wall-like portion 41 may be connected to the engine casing 9 via a bracket (not shown) or the like, or the engine casing 9 may constitute a part of the wall-like portion 41. Furthermore, in this embodiment, at least a portion of the casing 40 of the carbon dioxide recovery unit 20 is provided on the underside of the exposed deck 7. Alternatively, the entire casing 40 may be provided on the exposed deck 7.

[0029] Furthermore, the casing 40 may be formed to a length FA in the bow-stern direction corresponding to ISO (International Organization for Standardization) standard containers (for example, 20 feet or 40 feet in length). By forming it in this way, for example, when installing the carbon dioxide capture unit 20 on an existing container ship, and the container space adjacent to the bow-stern direction FA of the engine casing 9 is an ISO standard container space, it is possible to minimize the container space sacrificed by the installation of the carbon dioxide capture unit 20.

[0030] As shown in Figure 1, in this embodiment, the casing 40 of the carbon dioxide recovery unit 20 is positioned so that at least a portion of it overlaps with the engine room 3 when viewed from the vertical direction Dv. In this case, the casing 40 is mounted on top of the engine room 3.

[0031] In this embodiment, the shipboard compartment 2S is located below the exposed deck 7 and is equipped with a plurality of vertically extended steel members 22 extending in the vertical direction Dv. The exposed deck 7 is also provided with horizontally extended steel members (not shown) extending in the ship's width direction W, connecting the upper ends of these plurality of vertically extended steel members 22. These vertically extended steel members 22 and horizontally extended steel members are so-called main structural members, and are provided in multiples at intervals in the bow-stern direction FA. The columns 46 provided in the casing 40 of the carbon dioxide capture unit 20 are preferably positioned so as to overlap with the vertically extended steel members 22 (and horizontally extended steel members) when viewed from the vertical direction Dv. The loads of the casing 40 and the carbon dioxide capture unit 20 can be transmitted (or transferred) to the structural members (not shown) of the hull 2 ​​by the wall-like sections and reinforcing materials provided within the hull 2, which are located below the vertically extended steel members 22, columns 46, and wall-like sections 41.

[0032] As shown in Figure 2, the carbon dioxide recovery unit 20 may further include a vibration suppression device 70 to suppress vibrations of the casing 40. The vibration suppression device 70 suppresses vibrations of the equipment 30 located inside the casing 40 of the carbon dioxide recovery unit 20 in response to the rocking of the hull 2 ​​and vibrations from the combustion device 8. As such a vibration suppression device 70, a vibration damping device such as a tuned mass damper may be used. Alternatively, as the vibration suppression device 70, for example, a seismic isolation rubber device may be provided between the casing 40 and the hull 2. Furthermore, a mass body may be provided as the vibration suppression device 70 to prevent the natural frequency of the carbon dioxide recovery unit 20 from resonating with the natural frequency of the combustion device 8.

[0033] (Effects and Benefits) In the container ship 1 of the above embodiment, the carbon dioxide recovery unit 20 has multiple types of equipment 30 arranged within the casing 40 for recovering carbon dioxide from exhaust gas supplied via the exhaust gas pipe 91 in the engine casing 9. Since the casing 40 is positioned adjacent to the engine casing 9 in the bow-stern direction FA, the narrowing of the container space S on the exposed deck 7 by piping 35, etc., for supplying exhaust gas from the exhaust gas pipe 91 to the equipment 30 of the carbon dioxide recovery unit 20 is minimized. As a result, it is possible to equip the ship with the carbon dioxide recovery unit 20 while minimizing the reduction in the loading capacity of the containers 100.

[0034] Furthermore, in the above embodiment, the casing 40 comprises a wall-like portion 41 and a ceiling portion 42, thereby housing multiple types of equipment 30 within the casing 40 and minimizing their exposure to the outside atmosphere.

[0035] Furthermore, in the above embodiment, the tower-shaped equipment 31 arranged in the casing 40 and the casing 40 are integrally connected via the intermediate deck 45, thereby suppressing vibration of the tower-shaped equipment 31 in response to the rocking of the hull 2 ​​and vibrations from the combustion device 8.

[0036] Furthermore, in the above embodiment, by providing multiple layers of intermediate decks 45 within the casing 40 at intervals in the vertical direction Dv, the tower-shaped equipment 31 extending in the vertical direction Dv can be stably supported.

[0037] Furthermore, in the above embodiment, since the casing 40 is equipped with columns 46 that support the intermediate deck 45, the load supported by the intermediate deck 45 is transmitted to the wall-like section 41 and the columns 46, allowing the tower-shaped equipment 31 to be supported more firmly.

[0038] Furthermore, in the above embodiment, the column 46 is positioned so as to overlap with the vertically extended steel members 22 provided inside the hull 2 ​​when viewed from the vertical direction Dv, thus enabling even more robust support for the tower-shaped equipment 31.

[0039] Furthermore, in the above embodiment, at least a portion of the casing 40 is positioned to overlap with the engine room 3 when viewed from the vertical direction Dv, so the space above the engine room 3 can be effectively utilized.

[0040] Furthermore, in the above embodiment, at least a portion of the casing 40 is provided on the underside of the exposed deck 7, which allows for effective use of space within the hull 2.

[0041] Furthermore, in the above embodiment, by providing the vibration suppression device 70, it is possible to suppress vibrations of the equipment 30 located inside the casing 40 of the carbon dioxide recovery unit 20 in response to the rocking of the hull 2 ​​and vibrations from the combustion device 8.

[0042] (Other embodiments) Although embodiments of this disclosure have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments and may include design changes and the like that do not depart from the gist of this disclosure. In the above embodiment, the configuration of the casing 40 housing multiple devices 30 was illustrated, but the configuration can be changed as appropriate. For example, in the above embodiment, a case in which a carbon dioxide recovery unit 20 that recovers carbon dioxide using an absorbent liquid is provided was described as an example, but the carbon dioxide recovery unit 20 is not limited to the above configuration as long as it is capable of recovering carbon dioxide.

[0043] Figure 3 is a cross-sectional view of a modified embodiment of the present disclosure of a carbon dioxide capture unit, as seen from the bow-stern direction. As shown in Figure 3, the casing 40B of the carbon dioxide capture unit 20 may comprise a lower casing 401 extending in the ship width direction W, and an upper casing 402 extending upward from a part of the lower casing 401 in the ship width direction W. In this case, for example, the tower-shaped equipment 31 may be housed in the upper casing 402, and other equipment 30 may be housed in the lower casing 401. Alternatively, the container 100 may be loaded onto the lower casing 401, which extends in the ship width direction W, relative to the upper casing 402.

[0044] With this configuration, by housing some of the various types of equipment 30 for recovering carbon dioxide from exhaust gas in the lower casing 401, the number of equipment 30 housed in the upper casing 402 can be reduced, and the upper casing 402 extending upward can be made smaller.

[0045] In the above embodiment, the casing 40 is positioned so that at least a portion of it overlaps with the engine room 3 when viewed from the vertical direction Dv. However, the casing 40 may also be positioned so that it does not overlap with the engine room 3 when viewed from the vertical direction Dv.

[0046] <Note> The container ship 1 described in the embodiment can be understood, for example, as follows:

[0047] (1) The container ship 1 according to the first embodiment comprises a hull 2 ​​on which the exposed deck 7 is a container space S capable of loading a plurality of containers 100, an engine room 3 provided within the hull 2 ​​and housing a combustion device 8 for burning fuel, an engine casing 9 communicating with the upper part of the engine room 3 and projecting upward from the exposed deck 7 and housing an exhaust gas pipe 91 through which exhaust gas from the combustion device 8 flows, casings 40, 40B arranged adjacent to the engine casing 9 in the bow-stern direction FA and provided to project upward from the exposed deck 7, and a carbon dioxide recovery unit 20 arranged within the casings 40, 40B and having a plurality of types of equipment 30 for recovering carbon dioxide from exhaust gas supplied through the exhaust gas pipe 91 in the engine casing 9.

[0048] In this container ship 1, the carbon dioxide recovery unit 20 has multiple types of equipment 30 for recovering carbon dioxide from exhaust gas supplied via the exhaust gas pipe 91 in the engine casing 9, which are arranged in casings 40 and 40B. Since these casings 40 and 40B are positioned adjacent to the engine casing 9 in the bow-stern direction FA, the reduction in the container space S on the exposed deck 7 due to piping 35, etc., for supplying exhaust gas from the exhaust gas pipe 91 to the equipment 30 of the carbon dioxide recovery unit 20 is minimized. As a result, it is possible to equip the ship with the carbon dioxide recovery unit 20 while minimizing the reduction in the container load capacity 100.

[0049] (2) The container ship 1 according to the second embodiment is the container ship 1 of (1), wherein the casings 40, 40B include a wall-like portion 41 that covers the entire circumference of the multiple types of equipment 30, and a ceiling portion 42 that covers the upper end opening of the wall-like portion 41 from above.

[0050] As a result, the casings 40 and 40B, equipped with a wall-like section 41 and a ceiling section 42, can house multiple types of equipment 30 within the casings 40 and 40B, minimizing their exposure to the outside atmosphere.

[0051] (3) The container ship 1 according to the third embodiment is the container ship 1 of (2), wherein at least a portion of the multiple types of equipment 30 is a tower-shaped equipment 31 extending in the vertical direction Dv, and the wall-shaped portion 41 and the tower-shaped equipment 31 are integrally connected via an intermediate deck 45.

[0052] As a result, the tower-shaped equipment 31 located in the casings 40 and 40B is integrally connected to the casings 40 and 40B via the intermediate deck 45, thereby suppressing vibrations of the tower-shaped equipment 31 in response to the rocking of the hull 2 ​​and vibrations from the combustion device 8.

[0053] (4) The container ship 1 according to the fourth embodiment is the container ship 1 of (3), wherein the intermediate deck 45 is a plate that extends along the horizontal plane, and the intermediate deck 45 is provided in multiple layers within the casings 40, 40B with intervals in the vertical direction Dv.

[0054] As a result, by providing multiple layers of plate-shaped intermediate decks 45 within the casings 40 and 40B at intervals in the vertical direction Dv, the tower-shaped equipment 31 extending in the vertical direction Dv can be stably supported.

[0055] (5) The container ship 1 according to the fifth embodiment is the container ship 1 of (4), further comprising within the casings 40, 40B columns 46 that extend in the vertical direction Dv and support the intermediate deck 45.

[0056] This allows the tower-like equipment 31 to be more firmly supported by providing columns 46 that support the intermediate deck 45 within the casings 40 and 40B.

[0057] (6) The container ship 1 according to the sixth embodiment is the container ship 1 of (5), wherein the column 46 is located in a position that overlaps with the vertically extended steel member 22, which is provided inside the hull 2 ​​and extends in the vertical direction Dv, when viewed from the vertical direction Dv.

[0058] As a result, the column 46 is positioned so as to overlap with the vertically extended steel members 22 installed inside the hull 2 ​​when viewed from the vertical direction Dv, thus providing even stronger support for the tower-like equipment 31.

[0059] (7) The container ship 1 according to the seventh embodiment is any one of the container ships 1 from (1) to (6), wherein the casing 40 is located such that, when viewed from the vertical direction Dv, at least a portion of it overlaps with the engine room 3.

[0060] As a result, at least a portion of the casing 40 is positioned to overlap with the engine compartment 3 when viewed from the vertical direction Dv, thus allowing for effective use of the space above the engine compartment 3.

[0061] (8) The container ship 1 according to the eighth embodiment is any one of the container ships 1 from (1) to (7), wherein the casing 40B has a lower casing 401 extending in the ship width direction W and an upper casing 402 extending upward from a part of the lower casing 401 in the ship width direction W.

[0062] This allows some of the various types of equipment 30 for recovering carbon dioxide from exhaust gas to be housed in the lower casing 401, thereby reducing the number of equipment 30 housed in the upper casing 402 and enabling a miniaturization of the upper casing 402 that extends upward.

[0063] (9) The container ship 1 according to the ninth embodiment is any one of the container ships 1 from (1) to (8), wherein the carbon dioxide recovery unit 20 is provided such that at least a portion of the casings 40, 40B is located below the exposed deck 7.

[0064] As a result, at least a portion of the casings 40 and 40B are located below the exposed deck 7, allowing for effective use of space within the hull 2.
