Description

Technical Field

[0001] The present invention relates to the technical field of container ships, and specifically to a hydrogen fuel cell-powered container ship with low carbon emissions. Background Art

[0002] Compared with traditional fuel-powered container ships, using a hydrogen fuel cell as the power source for a container ship not only provides stronger endurance but also reduces carbon dioxide emissions, thereby achieving low carbon emissions and reducing pollution.

[0003] For example, in the prior art, the patent with the publication number "CN115384746A" and the patent name "A near-zero emission logistics system for large container ships" discloses that a fuel cell compartment is provided below the superstructure, an engine room is provided below the upper deck near the stern of the near-zero emission container ship, an ammonia fuel storage tank is arranged below the upper deck and in the cargo hold section between the superstructure and the engine room, and the ammonia fuel storage tank is far from the superstructure, minimizing the impact of dangerous areas and toxic gas diffusion on personnel. The fuel cell compartment is arranged below the superstructure, effectively utilizing the space below the superstructure and simultaneously solving the problem of crowded engine room space. The fuel cell compartment is equipped with hydrogen fuel cell modules to replace the power demand of the ship's main power station and simultaneously meet the large-capacity power station demand of ocean-going large container ships. The fuel cell energy storage system is composed of mobile containerized high-pressure hydrogen storage modules, occupying containers on the deck and enabling rapid loading and unloading. The gas treatment compartment is arranged above the ammonia fuel storage tank. Also, in the prior art, the patent with the publication number "CN117208187A" and the patent name "A zero-carbon emission container ship" discloses that the container ship includes a partition area provided on the main deck of the hull. A hydrogen fuel storage module is placed at the rear side of the partition area near the stern, and containerized goods are placed at the front side. The hydrogen fuel storage module and the containerized goods are separated by the partition area, which can ensure to the greatest extent that in case of accidents such as hydrogen fuel leakage and fire, the goods in front will not be affected. The hydrogen fuel storage module is designed as a container type and is directly installed in the open area at the rear side of the partition area. When docking at a port, the container can be directly replaced, eliminating the step of refueling. At the same time, a supporting hydrogen fuel preparation room and a hydrogen fuel connection point are arranged in the partition area to transport hydrogen fuel to the hydrogen fuel cell module. The ship is also provided with an electric energy storage module, which is also designed as a container type for convenient direct container replacement operation and is arranged at the rear side of the partition area as a supplementary power source. In addition, several water mist nozzles are arranged in the partition area for fire protection to ensure safety.

[0004] In the existing hydrogen fuel cell-powered container ship in the above-mentioned prior art, during use, hydrogen fuel is directly transported to the hydrogen fuel cell module for use. Since the hydrogen fuel cannot be filtered first, there will still be some impurities in the hydrogen fuel during use. These impurities will damage the catalyst and membrane electrode in the hydrogen fuel cell, thus affecting the reaction efficiency and service life of the hydrogen fuel cell in the ship's propulsion power equipment. At the same time, it will also affect the effect of low-carbon emissions. Therefore, we propose a low-carbon emission hydrogen fuel cell-powered container ship to solve the problems raised above.

It can effectively reduce the pressure drop when hydrogen fuel passes through the filter assembly, avoiding affecting the gas supply pressure of the hydrogen fuel cell body, thereby ensuring the efficient operation of the hydrogen fuel cell body. The specific content is as follows:

[0017] (1) The filter assembly in the filter can filter hydrogen fuel, remove impurities in the hydrogen fuel, avoid damage to the catalyst and membrane electrode in the hydrogen fuel cell body by impurities in the later stage, thereby improving the reaction efficiency and service life of the hydrogen fuel cell, and also achieving the effect of low carbon emissions;

[0018] Furthermore, through the optimized design of the structure of the filter, the hydrogen fuel in the temporary storage box can enter the filter assembly evenly through the shunt pipe that rotates and moves at the same time for filtering operations, thereby avoiding excessive local resistance of the filter assembly. Therefore, the pressure drop when hydrogen fuel passes through the filter assembly can be effectively reduced, avoiding affecting the gas supply pressure of the hydrogen fuel cell body, and thus ensuring the efficient operation of the hydrogen fuel cell body.

[0019] (2) Through the cooperative design of the fixed disk that does not move and the control disk, the control disk can drive the shunt pipe to revolve around the first fixed pipe while driving the shunt pipe to move reciprocally, so that the shunt pipe can evenly transport hydrogen fuel to each position;

[0020] Furthermore, through the cooperative use of the second fixed pipe and the second piston column, the first piston column can be driven to slide back and forth reciprocally, and then the first piston column can push the support rod and the filter assembly to shake back and forth reciprocally, thereby facilitating the shaking off of impurities on the filter assembly and avoiding affecting the filtering operation of the filter assembly.

[0021] (3) The cooling base can not only collect the generated water, but also recover the heat generated by the hydrogen fuel cell body through the water, and then transport the water with heat to the heat preservation box. It can not only keep the outside of the preheater warm, but also utilize the recovered heat, thereby reducing energy waste;

[0022] Furthermore, the water in the heat preservation box drives the water wheel mechanism and the transmission vertical rod to rotate.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-13 , the present invention provides the following technical solutions:

[0039] Embodiment 1: The low-carbon-emission hydrogen fuel cell-powered container ship in this embodiment can remove impurities in the hydrogen fuel, thereby improving the reaction efficiency and service life of the hydrogen fuel cell, achieving the effect of low carbon emissions, and effectively reducing the pressure drop when the hydrogen fuel passes through the filter assembly 18, thereby ensuring the efficient operation of the hydrogen fuel cell body 10. The specific structure is as shown in the attached Figures 1-10 figure, including a hull 1, and a deck 2 for placing containers installed inside the upper part of the hull 1. A propeller 3 is installed on the right bottom surface of the hull 1. A bottom plate 13 is installed inside the lower part of the hull 1. A bearing frame 17 and a conveying control mechanism 6 are installed above the left side of the bottom plate 13 through a mounting frame 14. A hydrogen storage tank 5 is placed inside the bearing frame 17. The pipeline at the front end of the hydrogen storage tank 5 is connected to the pipeline at the front end of the conveying control mechanism 6. The right side of the conveying control mechanism 6 is connected to a filter 7 installed above the bottom plate 13 through a pipeline. The right side of the filter 7 is connected to a hydrogen fuel cell body 10 installed above the right side of the bottom plate 13 through a pipeline. A flow control mechanism for controlling the uniform delivery of hydrogen fuel is connected to the left side of the filter 7. The rear side of the hydrogen fuel cell body 10 is connected to a blower 12 installed inside the hull 1 through a pipeline. The air inlet pipe 4 installed at the other end of the blower 12 penetrates the rear side of the hull 1.

[0040] The flow control mechanism includes a temporary storage box 15 rotatably installed on the left side of the filter 7. The inside of the temporary storage box 15 is hollow. The pipe on the right side of the conveying control mechanism 6 penetrates and rotates into the temporary storage box 15. A circle of shunt pipes 21 is equidistantly installed on the right side surface of the temporary storage box 15. The shunt pipes 21 are arranged in a "Z" shape. The right end of the shunt pipe 21 is inserted into the left side inside of the filter 7. A control gear 151 is installed on the outside of the temporary storage box 15. The rear side of the control gear 151 is meshed with a transmission gear 16 installed in the hull 1. The right end of the transmission gear 16 is connected to a motor installed in the hull 1. A support rod 181 is slidably connected through a bracket on the right side inside of the filter 7. A connecting spring 182 is nested on the outer side of the right end of the support rod 181. Three sets of filter components 18 with different internal apertures are sequentially installed on the outer side of the left end of the support rod 181. The outer sides of the filter components 18 are attached to the inner wall of the filter 7. A circle of fixed disks 20 is equidistantly installed on the left inner wall of the filter 7. The outer sides of the fixed disks 20 are arc-shaped. A control disk 22 is fixedly penetrated on the outer side of the right end of the shunt pipe 21. A convex rod 221 is fixed below the left side of the control disk 22. A circle of limit rods 222 is installed in slots at equal intervals on the inside of the right side surface of the temporary storage box 15. The convex rod 221 penetrates through the outer side of the limit rod 222. A return spring 223 is nested on the outer side of the limit rod 222. The middle position of the shunt pipe 21 is made of flexible pipe material. The control disk 22 forms a reciprocating sliding structure through the fixed disk 20. A first fixed pipe 19 is fixed at the middle position of the right side surface of the temporary storage box 15. The right end inside of the first fixed pipe 19 is connected with a first piston rod 191. The right end of the first piston rod 191 is provided with the support rod 181. The support rod 181 forms a left-right reciprocating sliding structure through the first piston rod 191. A circle of second fixed pipes 23 is fixedly penetrated at equal intervals on the outer side of the left end of the first fixed pipe 19. One end inside of the second fixed pipe 23 is attached and connected with a second piston rod 231. The other end of the second piston rod 231 is connected with the convex rod 221.

[0041] During the operation of the hydrogen fuel cell-powered container ship, hydrogen fuel in the hydrogen storage tank 5 is transported into the filter 7 through the transportation control mechanism 6. At this time, the hydrogen fuel first enters the temporary storage frame 15 rotatably connected to the left side of the filter 7, and then the hydrogen fuel enters the filter 7 through multiple shunt tubes 21. At the same time, the motor behind the filter 7 is started, and the motor drives the transmission gear 16 to rotate. When the transmission gear 16 rotates, it drives the temporary storage frame 15 to rotate through the meshing control gear 151. When the temporary storage frame 15 rotates, it drives multiple "Z"-shaped shunt tubes 21 to revolve around the first fixed tube 19 as the center. At the same time, when the control disk 22 on the outer side of the shunt tube 21 rotates to contact and fit with the fixed disk 20, the stationary fixed disk 20 will exert an inward thrust on the control disk 22, causing the control disk 22 to stretch the hose structure in the middle area of the shunt tube 21. As a result, the control disk 22 drives the right end of the shunt tube 21 to move inward well. At this time, the convex rod 221 on the left side of the control disk 22 moves downward on the outside of the limit rod 222, and at the same time, the return spring 223 is compressed and stores energy. When the control disk 22 rotates to separate from the fixed disk 20, as shown above, similarly, the return spring 223 automatically drives the control disk 22 to reset by the stored energy. By repeating such operations, the shunt tube 21 revolves around the center of the first fixed tube 19 while the right end of the shunt tube 21 moves reciprocally. As a result, the shunt tube 21 can evenly transport the hydrogen fuel into the filtering assembly 18 for filtering operations, thereby avoiding excessive local resistance of the filtering assembly 18 and preventing the supply pressure of the hydrogen fuel cell from being affected.

[0042] Then, the hydrogen fuel can be filtered through the filtering component 18 to remove impurities in the hydrogen fuel, avoiding damage to the catalyst and membrane electrode in the hydrogen fuel cell body 10 caused by impurities in the later stage, achieving the effect of low carbon emissions. At the same time, the convex rod 221 will drive the second piston rod 231 to move inward together. At this time, the second piston rod 231 will squeeze and convey some of the gas in the second fixed tube 23 into the first fixed tube 19, thereby enabling the gas to automatically push the first piston rod 191 to move to the right. By repeating such operations, the first piston rod 191 can move left and right reciprocally to intermittently push the support rod 181 to the right. At the same time, with the use of the connecting spring 182, the filtering component 18 can be automatically driven to move left and right reciprocally, so that the filtering component 18 generates a certain shaking force, facilitating the shaking off of impurities on the surface of the filtering component 18 and avoiding affecting the filtering operation of the filtering component 18. Then, the filtered hydrogen fuel can enter the anode of the hydrogen fuel cell body 10 through the pipeline and the connecting pipe 27. At this time, the blower 12 is started, and the blower 12 introduces external air into the cathode of the hydrogen fuel cell body 10 through the air inlet pipe 4. Inside the hydrogen fuel cell body 10, hydrogen and oxygen undergo an electrochemical reaction to generate electric energy and water. The electric energy generated by the hydrogen fuel cell body 10 is distributed to the propulsion motor inside the right side of the hull 1 through the power management system, and then the propulsion motor drives the propeller 3 to push the container ship to sail. Since this part is prior art, no detailed introduction will be made here.

[0043] Embodiment 2: In the low-carbon emission hydrogen fuel cell-powered container ship in this embodiment, on the basis of Embodiment 1, not only can the heat generated by the hydrogen fuel cell body 10 be recovered and reused, but also the preheating effect of the hydrogen fuel can be improved, enhancing the overall performance and economy of the hydrogen fuel cell body 10. The specific structure is as shown in the attached Figures 3-5 and Figure 11 As shown, the bottom surface of the hydrogen fuel cell body 10 is installed on the bottom plate 13 through the cooling base 11. A preheater 8 is provided on the bottom plate 13 between the filter 7 and the hydrogen fuel cell body 10. A heat preservation frame 9 is installed outside the preheater 8, and the heat preservation frame 9 is installed on the bottom plate 13. Both the heat preservation frame 9 and the cooling base 11 are arranged in a "U" shape and are hollow inside for storing water and recovering and reusing waste heat. A drainage pipe is installed on the bottom surface of the heat preservation frame 9. A transmission vertical rod 24 is rotatably installed inside the rear side surface of the heat preservation frame 9. A water wheel mechanism 25 is fixed on the outer side above the transmission vertical rod 24. The middle outer side of the transmission vertical rod 24 is connected to the rear end of a transmission cross rod 26 installed inside the preheater 8 through a set of bevel gear sets. The front end of the transmission cross rod 26 is connected to a connecting pipe 27 penetrating through the preheater 8 through another set of bevel gear sets. The connecting pipe 27 is rotationally connected to the pipelines on the left and right sides through a sealed bearing. A drainage pipe is installed on the bottom surface of the heat preservation frame 9.

[0044] The water generated by the electrochemical reaction enters the "U"-shaped cooling base 11 with a hollow interior through a water pump to cool down the hydrogen fuel cell body 10, and at the same time, the heat can be recovered. Then, the water that recovers heat in the cooling base 11 enters the "U"-shaped heat preservation frame 9 with a hollow interior through a pipeline, so that the water in the heat preservation frame 9 can keep the outside of the preheater 8 warm and prevent the heat in the preheater 8 from diffusing outward. At the same time, the preheater 8 is turned on, and the heating wire in the preheater 8 generates a certain amount of heat to preheat the hydrogen fuel in the connecting pipe 27. The water in the heat preservation frame 9 is later discharged through the pipeline at the bottom. At the same time, when the water in the heat preservation frame 9 flows, it will drive the water wheel mechanism 25 and the transmission vertical rod 24 to rotate. Then, the transmission vertical rod 24 drives the transmission cross rod 26 to rotate through the bevel gear assembly, and the transmission cross rod 26 drives the connecting pipe 27 to rotate through the bevel gear assembly. Thus, when the connecting pipe 27 rotates, the hydrogen fuel in the connecting pipe 27 can be uniformly preheated, thereby improving the preheating effect and enhancing the overall performance and economy of the hydrogen fuel cell body 10.

[0045] Embodiment 3: In the low-carbon-emission hydrogen fuel cell-powered container ship in this embodiment, on the basis of Embodiment 1, it is convenient to separate the carrier frame 17 from the mounting frame 14, so as to facilitate the disassembly and replacement of the carrier frame 17 in the later stage. The specific structure is referred to in the attached Figure 5 and the attached Figures 12-13 As shown, a bidirectional lead screw 281 and a guide rod 282 are installed through the interior of the mounting frame 14. Threaded connections are provided through the outer sides of the left and right ends of the bidirectional lead screw 281 with "7"-shaped fixing blocks 28. A guide rod 282 is provided through the interior of the fixing block 28. One end of the fixing block 28 is inserted into the carrier frame 17. The lower part of the carrier frame 17 is in concave-convex fit with the groove above the mounting frame 14. A cover plate 201 is rotatably installed inside the left side of the deck 2. The length and width of the cover plate 201 are respectively larger than the length and width of the corresponding carrier frame 17 below.

[0046] When the hydrogen fuel in the hydrogen storage tank 5 is used up and needs to be replaced, the cover plate 201 is rotated and opened at this time, and then the bidirectional lead screw 281 is manually rotated. When the bidirectional lead screw 281 rotates, it drives the "7"-shaped fixing blocks 28 threadedly connected to the outer sides of the left and right ends to move outward. The guide rod 282 ensures the stable movement of the fixing block 28. When the fixing block 28 moves to a position separated from the carrier frame 17, the rotation of the bidirectional lead screw 281 is stopped at this time. Then, the pipeline on the front side of the hydrogen storage tank 5 is separated from the pipeline on the front side of the conveying control mechanism 6. Then, the carrier frame 17 can be moved upward by a crane or other equipment, so that the carrier frame 17 is separated from the mounting frame 14, and the carrier frame 17 and the hydrogen storage tank 5 are carried out of the hull 1 for replacement, and the operation is convenient.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
