Description

TECHNICAL FIELD

[0002] According to the carbon emission reduction target set by the International Maritime Organization (IMO), the annual carbon emission of international shipping must be reduced by at least 40% compared with that in 2008 by 2030, and must be reduced by at least 50% by 2050. In order to achieve the above target, it is urgent to introduce a practical carbon emission reduction solution on the ship.

[0003] For a container ship, especially a large container ship, its huge loading capacity leads to high energy consumption, resulting in higher carbon emission reduction requirements for the container ship.

DETAILED DESCRIPTION

[0030] ​To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] Container ships, especially large container ships, have high energy consumption due to their huge carrying capacity. Therefore, compared with other ship types, container ships have higher requirements for carbon emission reduction.

[0033] Currently, mainstream container ships have had to adopt a dual-fuel solution to address this issue. A dual-fuel solution requires an additional dedicated fuel tank for the second fuel (typically LNG or methanol). While achieving carbon emission reduction, the dual-fuel solution sacrifices some cargo space, reducing the ship's economic performance. Furthermore, the fuel tanks must be interspersed among the cargo holds, requiring numerous structural reinforcements and increasing the ship's structural weight.

[0034] To address the aforementioned carbon emission reduction issues faced by container ships, this application provides a novel container ship that cleverly and rationally applies carbon capture, utilization, and storage (CCUS) technology to container ships, without excessively increasing the cargo capacity and complexity of the merchant ship, and enabling the carbon to be used and consumed on board immediately after capture. See details... Figures 1-3 The container ship disclosed in this application includes a carbon absorption system 100, a carbon separation system 200, a carbon purification and liquefaction system 300, and an onboard fire protection system.

[0035] The carbon absorption system 100 is integrated in the first container, the inlet 110 of the carbon absorption system is communicated with the exhaust port of the main engine 500 of the ship body, the carbon-containing flue gas discharged from the main engine 500 is changed into decarbonized flue gas and rich liquid by absorbing or capturing carbon dioxide through the carbon absorption system 100, the rich liquid is CO2-containing absorption liquid, the decarbonized flue gas is discharged along the chimney 510, and the rich liquid is discharged from the liquid outlet 120 of the carbon absorption system 100. The carbon separation system 200 is integrated in the second container, the inlet 210 of the carbon separation system is connected to the liquid outlet 120 of the carbon absorption system 100, the rich liquid discharged from the carbon absorption system 100 is converted into gaseous carbon dioxide and lean liquid not containing carbon dioxide through the carbon separation system 200, and the gaseous carbon dioxide is discharged along the outlet 220 of the carbon separation system. The carbon purification and liquefaction system 300 is integrated in the third container, is communicated with the outlet 220 of the carbon separation system, and is used for compressing, purifying and liquefying the gaseous carbon dioxide, so that the gaseous carbon dioxide becomes liquid carbon dioxide which can be stored in liquid state through the carbon purification and liquefaction system 300. The shipboard fire extinguishing system comprises a carbon dioxide storage tank 400 and a conveying pipeline, the carbon dioxide storage tank 400 is integrated in at least one fourth container, liquid carbon dioxide flows into and is stored in the carbon dioxide storage tank 400, and the liquid carbon dioxide in the carbon dioxide storage tank 400 is conveyed to the area to be extinguished of the ship body along the conveying pipeline.

[0036] The specific installation position of the container can be seen from Figure 1 and Figure 2 The first container, the second container, the third container and the at least one fourth container integrated with the carbon absorption system 100, the carbon separation system 200, the carbon purification and liquefaction system 300 and the shipboard fire extinguishing system are arranged close to the chimney 510 of the engine room and on the side close to the stern of the chimney. The first container, the second container, the third container and the at least one fourth container are generally arranged in a concentrated manner and are not suitable for being arranged in a scattered manner, and in general, the first container, the second container, the third container and the at least one fourth container are arranged in a symmetrical manner in the ship width direction. A suitable number of containers can be provided as storage tanks according to the actual situation of the ship, and when the ship is docked, the containers in the carbon absorption system, the carbon separation system, the carbon purification and liquefaction system and the shipboard fire extinguishing system can be replaced, and the stored carbon dioxide can be transported to other places for reuse. When several containers are arranged on the side of the chimney, in the direction of movement of the ship, the carbon capture, utilization and storage system does not increase the wind area of the container ship, and has no effect on the wind resistance of the ship.

[0037] In another embodiment, without the requirement of the attitude and stability performance of the ship, several containers can also be arranged on the left (right) side of the chimney, on the front side of the chimney, on the middle part of the main deck (or convex deck), and on the bow part of the main deck (or convex deck).

[0038] In the above implementation process, by integrating the carbon capture, utilization and storage system on the container ship and organically combining with the fire extinguishing system on the ship, i.e. using the captured carbon dioxide as the fire extinguishing material of the carbon dioxide fire extinguishing system on the ship, the carbon capture and utilization during the voyage of the container ship are completed. Furthermore, the fuel tank in the current dual-fuel container ship can be cancelled on the container ship, i.e. the single-fuel (fuel oil) scheme of the ship meets the corresponding carbon emission requirements. The container ship disclosed in the present application can cancel the fuel tank to increase the cargo hold capacity of the ship and improve the economic performance of the ship. On the other hand, the carbon can be captured and utilized in real time to meet the carbon emission requirements and further improve the economic performance of the ship.
