[0030] The above is an introduction to the common structural arrangement of a cargo ship, and the following introduces the innovations of the cargo ship of the present utility model.
[0031] The cargo ship of the utility model has an important innovation in that a CCS system is arranged on the cargo ship, and the CCS system includes a carbon capture system and a liquid CO2 carbon storage system.
[0032] The carbon capture system is a device of the prior art, which has an exhaust gas inlet pipe port and a carbon output pipe port. The function of the carbon capture system is that the exhaust gas emitted by the marine engine enters the carbon capture system through the exhaust gas inlet pipe port, the carbon capture system performs carbon capture treatment on the received exhaust gas, and then discharges the captured carbon dioxide gas through the carbon output pipe port.
[0033] A carbon transport pipeline is provided between the carbon capture system and the liquid CO2 carbon storage system, and the carbon output pipe outlet of the carbon capture system is connected to the liquid CO2 carbon storage system through the carbon transport pipeline.
[0034] Those skilled in the art will appreciate that a gas compression and liquefaction device is usually provided in a liquid CO2 carbon storage system to facilitate the compression and liquefaction of carbon dioxide for storage.
[0035] An exhaust gas input pipeline is provided between the carbon capture system and the engine room, and the exhaust gas inlet pipe opening of the carbon capture system is connected to the exhaust gas outlet of the engine room through the exhaust gas input pipeline.
[0036] The exhaust gas generated by the main engine or auxiliary engine in the engine room burning LPG / LNG fuel or methanol fuel enters the carbon capture system through the exhaust gas input pipeline for carbon capture treatment. The carbon capture system transports the captured carbon dioxide gas through the carbon transmission pipeline and stores it in the liquid CO2 carbon storage system after liquefaction, thereby avoiding carbon emissions.
[0037] Three specific embodiments of cargo ships are provided below:
[0038] Implementation 1:
[0039] See also Figure 1 , Embodiment 1 provides a cargo ship equipped with a carbon capture system.
[0040] The cargo ship of this embodiment 1 has a deckhouse 1, a fuel tank 2 and an engine room; the deckhouse 1 is arranged on the main deck at the rear of the cargo ship, the engine room is arranged below the deckhouse 1 (not shown in the figure), the fuel tank 2 is arranged in front of the engine room, and ballast tanks 6 are symmetrically arranged on both sides of the fuel tank 2.
[0041] The carbon capture system 4 is arranged on the main deck and is located adjacent to the rear side of the deckhouse 1 .
[0042] Specifically, a room is provided near the rear side of the deck house 1, and the carbon capture system 4 is provided in the room. For the convenience of description, the room where the carbon capture system 4 is provided is referred to as a carbon capture system room.
[0043] The liquid CO2 carbon storage system comprises two large carbon storage chambers 5. As for a single carbon storage chamber 5, the carbon storage chamber 5 is a cylinder with two hemispherical ends.
[0044] The two carbon storage cabins 5 are also arranged on the main deck, and the two carbon storage cabins 5 are respectively located on both sides of the deck house 1, that is, the carbon storage cabins 5 are located between the deck house 1 and the side of the ship, and the two carbon storage cabins 5 are in a horizontal position, and the two carbon storage cabins 5 are symmetrically arranged on both sides of the deck house 1.
[0045] The previously mentioned “carbon output pipe of the carbon capture system is connected to the liquid CO2 carbon storage system through a carbon transport pipeline” actually means that the carbon output pipe of the carbon capture system 4 is connected to two carbon storage chambers 5. In this way, the carbon dioxide captured by the carbon capture system 4 is stored in the two carbon storage chambers 5 after compression and liquefaction.
[0046] It should be noted that a gas compression and liquefaction device is also provided at the entrance of the carbon storage cabin 5 so as to compress and liquefy the carbon dioxide, and then store the liquefied carbon dioxide in the carbon storage cabin 5 .
[0047] The arrangement of the first embodiment has the advantage that the carbon storage chambers 5 are arranged on both sides of the deck house 1, which reduces the length of the pipeline from the carbon capture system 4 to the carbon storage chambers 5, thereby saving costs.
[0048] Implementation 2:
[0049] See also Figure 2 and Figure 3, Embodiment 2 provides a cargo ship equipped with a carbon capture system.

For the convenience of description, the "combination of the ballast tank 6 and the side void tank 7" is referred to as the "ballast tank side void tank combination structure".
[0050] The ballast tank side void tank combination structure can be in two forms. One form is that the ballast tank 6 is above the side void tank 7, or in other words, the side void tank 7 is below the ballast tank 6. The other form is that the side void tank 7 is above the ballast tank 6, or in other words, the ballast tank 6 is below the side void tank 7.
[0051] In Embodiment 2, the location and form of the carbon capture system 4 are the same as those in Embodiment 1, and the main difference lies in the location and arrangement form of the liquid CO2 carbon storage system.
[0052] Specifically, in the present embodiment 2, the liquid CO2 carbon storage system includes two large carbon storage chambers 5. As for a single carbon storage chamber 5, the carbon storage chamber 5 is a cylinder with two hemispherical ends.
[0053] The two carbon storage tanks 5 are both located below the main deck, and are respectively arranged in the side void tanks 7 on both sides of the fuel tank 2. Due to the structural limitations of the side void tanks 7, the carbon storage tanks 5 are in a horizontal position in the side void tanks 7.
[0054] The arrangement of the second embodiment has the advantage that the carbon storage tank 5 is arranged on both sides of the fuel tank 2, which can save space on both sides of the deck house 1, facilitate the arrangement of the engine room and the deck house 1, and can use the space on both sides for other purposes, such as adding fuel tanks or arranging sails, etc. It is suitable for ships with tight arrangement or requiring a larger fuel tank volume.

[0058] In Embodiment 3, the location and form of the carbon capture system 4 are the same as those in Embodiment 1, and the main difference lies in the location and arrangement form of the liquid CO2 carbon storage system.
[0059] Specifically, in the present third embodiment, the liquid CO2 carbon storage system includes four large carbon storage chambers 5. As for a single carbon storage chamber 5, the carbon storage chamber 5 is a cylinder with two hemispherical ends.
[0060] The four carbon storage tanks 5 are all located below the main deck, and the four carbon storage tanks 5 are divided into two groups, each group has two carbon storage tanks 5, and the two groups of carbon storage tanks 5 are respectively arranged in the side empty tanks 7 on both sides of the fuel tank 2. Since the side empty tanks 7 are independent, their internal space is large, and therefore, the carbon storage tanks 5 are arranged in an upright state in the side empty tanks 7.
[0061] The arrangement of the third embodiment has the advantages that the carbon storage tank 5 is arranged on both sides of the fuel tank 2, which can save space on both sides of the deck house 1, facilitate the arrangement of the engine room and the deck house 1, and can use the space on both sides for other purposes, such as adding fuel tanks or arranging sails, etc., and can provide a carbon storage tank 5 with a larger capacity. It is suitable for ships with tight arrangement or requiring a larger fuel tank volume.
[0062] It should be noted that, in the above-mentioned embodiments 1, 2 and 3, the cargo ships mentioned therein are mainly VLOC ships.
[0063] It should be noted that in the above-mentioned embodiments 1, 2 and 3, the number of the carbon storage chambers 5 can be set to one or more depending on the amount of liquid carbon dioxide after carbon capture.
[0064] In the above-mentioned embodiments 1 to 3, a CCS system is installed on the cargo ship, and the CCS system includes a carbon capture system and a liquid CO2 carbon storage system. After the carbon capture system receives the "exhaust gas generated by the main engine or auxiliary engine in the engine room burning organic fuel", it performs carbon capture treatment on the exhaust gas, and then transports the captured carbon dioxide gas to the liquid CO2 carbon storage system for storage, thereby avoiding carbon emissions and providing technical support for achieving carbon reduction targets.
[0065] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
