Description

Technical Field

[0001] This application relates to the field of marine technology, and in particular to a split-type marine LNG-powered fuel tank container. Background Technology

[0002] Natural gas, as a clean and efficient gaseous fuel, has become an important energy source for 21st-century economic development due to its significant advantages in environmental impact and energy efficiency. The development of liquefied natural gas (LNG) technology has been accompanied by advancements in energy technology, cryogenic technology, and materials technology, leading to its widespread application in transportation vehicles such as automobiles, ships, airplanes, and trains, as well as in the utilization of cold energy.

[0003] Currently, the fuel tank and vaporizer in marine LNG-powered fuel tank containers are fixed to a single frame and are a single, integrated structure. This presents numerous inconveniences during transportation, installation, and subsequent maintenance. Furthermore, the service lives of the fuel tank and vaporizer are not entirely the same; when one component is decommissioned, the other component must be decommissioned prematurely due to the integrated structure, resulting in unnecessary resource waste. Therefore, this application provides a separate marine LNG-powered fuel tank container. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a split-type marine LNG power fuel tank container, comprising a frame, a power fuel tank, a vaporizer, and a connecting hose. The power fuel tank is fixed within the frame, which is detachably fixed to the power vessel. The power fuel tank has an outlet pipe communicating with the inner cavity of the power fuel tank, and the end of the outlet pipe away from the power fuel tank is connected to the connecting hose. The vaporizer is detachably fixed to the power vessel, and the vaporizer has an inlet pipe communicating with the inner cavity of the vaporizer. The end of the connecting hose away from the outlet pipe is connected to the inlet pipe.

[0005] In some embodiments, the power fuel tank is further provided with a pressurized liquid outlet pipe and a pressurized gas return pipe, and the vaporizer is provided with a pressurized liquid inlet pipe and a pressurized gas outlet pipe. The pressurized liquid outlet pipe and the pressurized liquid inlet pipe, as well as the pressurized gas return pipe and the pressurized gas outlet pipe, are connected by connecting hoses.

[0006] In some embodiments, both ends of the connecting hose are connected to a first connecting flange, and the ends of the liquid outlet pipe, the pressurized liquid outlet pipe, the pressurized air return pipe, the liquid inlet pipe, the pressurized liquid inlet pipe, and the pressurized air outlet pipe that are connected to the connecting hose are all connected to a second connecting flange that matches the first connecting flange.

[0007] In some embodiments, a first base fixed to the power ship is also included, with the frame being detachably and fixedly connected to the first base.

[0008] In some embodiments, a second base fixed to the power ship is also included, the vaporizer being detachably and fixedly connected to the second base, and the second base being symmetrically located on both sides of the first base.

[0009] In some embodiments, a cold box is also included that is detachably and fixedly mounted on a second base, with the vaporizer fixedly mounted inside the cold box.

[0010] In some embodiments, a buffer tank is also included, which is fixedly installed inside the cold box and connected to the vaporizer.

[0011] In some embodiments, the fuel tank is equipped with a safety valve.

[0012] Compared with existing technologies, in this application, the power fuel tank and the vaporizer are installed separately on the power ship and connected by a connecting hose, realizing the separate disassembly and connection of the vaporizer and the power fuel tank. This facilitates the transportation and installation of the vaporizer and the power fuel tank, and also avoids resource waste caused by the different service lives of the vaporizer and the power fuel tank, effectively reducing costs and improving economic efficiency. At the same time, the connection method of the connecting hose also greatly improves the freedom of installation of the relative positions of the vaporizer and the thermal power fuel tank.

[0020] Please see Figures 1-2 As shown in the figure, the present application provides a split-type marine LNG power fuel tank container, including a frame 1, a power fuel tank 2, a vaporizer 3, and a connecting hose 4. The power fuel tank 2 is fixed inside the frame 1, and the frame 1 is detachably fixed to the power ship. The power fuel tank 2 has an outlet pipe 21 that communicates with the inner cavity of the power fuel tank 2. The end of the outlet pipe 21 away from the power fuel tank 2 is connected to the connecting hose 4. The vaporizer 3 is detachably fixed to the power ship, and the vaporizer 3 has an inlet pipe 31 that communicates with the inner cavity of the vaporizer 3. The end of the connecting hose 4 away from the outlet pipe 21 is connected to the inlet pipe 31.

[0021] In the above embodiments, it should be understood that the power fuel tank 2 and the gasifier 3 can be disassembled from the power ship and hoisted to shore for replacement.

[0022] In the above embodiment, the power fuel tank 2 is first fixedly installed on the power ship based on the frame 1, and the vaporizer 3 is fixedly installed on the power ship and positioned opposite to the power fuel tank 3. Then, the liquid outlet pipe 21 on the power fuel tank 2 is connected to the liquid inlet pipe 31 on the vaporizer 3 using a connecting hose 4. At this time, LNG liquefied natural gas in the power fuel tank 2 can be transported to the vaporizer 3 for vaporization, so that the LNG is converted into gaseous natural gas for use by gas-using equipment on the power ship. Therefore, this application realizes the separate installation of the power fuel tank 2 and the vaporizer 3, which not only facilitates the transportation and installation of the vaporizer 3 and the power fuel tank 2, but also avoids resource waste caused by the different service lives of the vaporizer 3 and the power fuel tank 2, effectively reducing costs and improving economic efficiency. At the same time, the connection method using the connecting hose 4 also greatly improves the freedom of installation position of the vaporizer 3 and the thermal power fuel tank 2.

[0023] In some embodiments, the power fuel tank 2 is also provided with a pressurized liquid outlet pipe 22 and a pressurized gas return pipe 23, and the vaporizer 3 is provided with a pressurized liquid inlet pipe 32 and a pressurized gas outlet pipe 33. The pressurized liquid outlet pipe 22 and the pressurized liquid inlet pipe 32, as well as the pressurized gas return pipe 23 and the pressurized gas outlet pipe 33, are all connected by a connecting hose 4.

[0024] In the above embodiments, by setting up a pressurized liquid outlet pipe 22 and a pressurized liquid inlet pipe 32 connected by a connecting hose 4, it is ensured that LNG can be smoothly transported to the vaporizer 3 when the power fuel tank 2 is in a low liquid level or low pressure state. By setting up a pressurized gas return pipe 23 and a pressurized gas outlet pipe 33 connected by a connecting hose 4, the pressure is reduced between the vaporizer 3 and the power fuel tank 2, thereby avoiding overpressure in the vaporizer 3 or the power fuel tank 2 and ensuring the safety of the operation process.

[0025] In some embodiments, both ends of the connecting hose 4 are connected to a first connecting flange 5, and the ends of the liquid outlet pipe 21, the pressurized liquid outlet pipe 22, the pressurized air return pipe 23, the liquid inlet pipe 31, the pressurized liquid inlet pipe 32, and the pressurized air outlet pipe 33 that are connected to the connecting hose 4 are all connected to a second connecting flange 6 that matches the first connecting flange 5.

[0026] In the above embodiments, by setting matching first connecting flange 5 and second connecting flange 6, it is possible to ensure the quick connection of connecting hose 4, and at the same time ensure the reliability of the connection between connecting hose 4 and liquid outlet pipe 21, pressurized liquid outlet pipe 22, pressurized air return pipe 23, liquid inlet pipe 31, pressurized liquid inlet pipe 32 and pressurized air outlet pipe 33.

[0027] In some embodiments, a first base fixed to the power ship is also included, and the frame 1 is detachably and fixedly connected to the first base.

[0028] In the above embodiments, based on the first base mounting frame 1, on the one hand, the first base plays a guiding role in the installation process of the frame 1, and on the other hand, since the first base has a certain height, it is also convenient for the operator to fix the frame 1 on the first base, which improves the installation efficiency to a certain extent.

[0029] In some embodiments, a second base fixed to the power ship is also included, the vaporizer 3 is detachably fixed to the second base, and the second base is symmetrically located on both sides of the first base.

[0030] In the above embodiments, the second base not only serves as a guide during the installation of the vaporizer 3, but also facilitates the operator in performing fixed installation operations.

[0031] In some embodiments, a cold box 9 is also included that is detachably and fixedly mounted on a second base, and a vaporizer 3 is fixedly mounted inside the cold box 9.

[0032] In the above embodiments, by providing a cold box 9 for fixing the vaporizer 3, on the one hand, the cold box 9 can protect the vaporizer 3 from external dust and other impurities entering the vaporizer 3; on the other hand, the cold box 9 can be set as a square or other shape structure that is easy to install and matches the second base, so that the operator can fix the vaporizer 3 on the power ship.

[0033] In some embodiments, a buffer tank 7 is also included, which is fixedly installed inside the cold box 9 and connected to the vaporizer 3.

[0034] In the above embodiments, by setting a buffer tank 7 inside the cold box 9, on the one hand, the buffer tank 7 can be used to temporarily store the natural gas after it has been vaporized by the vaporizer 3 to ensure the pressure and flow rate of the natural gas supply; on the other hand, the cold box 9 can also protect the buffer tank 7 to prevent it from colliding with the outside.

[0035] In some embodiments, the power fuel tank 2 is equipped with a safety valve 8.

[0036] In the above embodiments, the safety valve 8 installed on the power fuel tank 2 can ensure the safety of the operation process and avoid the occurrence of safety accidents.

[0037] It should be noted that buffer pads can be installed at the bottom of the first and second bases. These buffer pads can cushion the frame 1 and the cold box 9 during installation and descent, reducing the collision force between the frame 1 and the first base, and between the cold box 9 and the second base. Simultaneously, the upper openings of the first and second bases can be open-ended, which can guide the frame 1 and the cold box 9, effectively reducing installation difficulty.

[0038] like Figure 2 As shown, both sides of the power fuel tank 2 are equipped with cold boxes 9. Both sides of the power fuel tank 2 are equipped with liquid outlet pipe 21, pressurized liquid outlet pipe 22 and pressurized return gas pipe 23 connected to the vaporizer 3. The vaporizer 3 and buffer tank 7 in one cold box 9 are in working condition, while the vaporizer 3 and buffer tank 7 in the other cold box 9 are redundant to ensure the normal operation of the gas supply.

[0039] The foregoing has provided a detailed description of a split-type marine LNG-powered fuel tank container provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application; the descriptions of the embodiments above are merely for the purpose of helping to understand the core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
