[0034] When using a fuel storage and supply system to supply fuel to end-user equipment on a ship, in order to reduce the energy consumption of the ship and improve the economy, as Figure 1As shown in the figure, the present invention provides a fuel storage and supply system. The fuel storage and supply system includes a heavy oil storage tank 1, a partition tank 2, a heating assembly 3, a fuel transfer pump 5, and a supply assembly 6.
[0035] Among them, the heavy oil storage tank 1 has a first storage cavity for storing heavy oil. The partition tank 2 is arranged in the heavy oil storage tank 1, and the partition tank 2 has a second storage cavity communicating with the first storage cavity. The heating assembly 3 is arranged in the first storage cavity and the second storage cavity. The heating assembly 3 can heat the heavy oil in the first storage cavity and the second storage cavity, so that the heavy oil in the first storage cavity is at a first temperature, and the heavy oil in the second storage cavity is at a second temperature, and the first temperature is lower than the second temperature. The inlet end of the fuel transfer pump 5 communicates with the second storage cavity. The supply assembly 6 communicates with the outlet end of the fuel transfer pump 5, and the supply assembly 6 communicates with the end-user equipment 7.
[0036] By heating the heavy oil in the first storage cavity through the heating assembly 3, the heated heavy oil can enter the second storage cavity. After the heavy oil in the second storage cavity is heated by the heating assembly 3, it is transported to the supply assembly 6 through the fuel transfer pump 5 and enters the end-user equipment 7 for use. By heating the heavy oil through the heating assembly 3, the heavy oil in the partition tank 2 has a higher temperature, which can ensure higher fluidity, thus facilitating the pumping by the fuel transfer pump 5. Moreover, when using the heating assembly 3 to heat the heavy oil, the heavy oil in the heavy oil storage tank 1 has a lower temperature, which can reduce the energy consumption of heating the heavy oil in the heavy oil storage tank 1, thereby reducing the energy consumption of the ship and improving the economy.
[0037] In some embodiments, the heating assembly 3 includes a first pipeline 31 and a second pipeline 32 connected in series. The first pipeline 31 is arranged in the first storage cavity, and the second pipeline 32 is arranged in the second storage cavity. The heating medium enters through the second pipeline 32 and exits from the first pipeline 31. In this embodiment, the heating medium can be steam or hot oil. The heating medium enters through the second pipeline 32. At this time, the temperature of the heating medium is relatively high. By exchanging heat with the heavy oil in the second storage cavity, the temperature of the heavy oil in the second storage cavity can be quickly increased, so that the temperature of the heavy oil in the second storage cavity quickly reaches the second temperature. The heating medium with reduced temperature flows into the first pipeline 31 and exchanges heat with the heavy oil in the first storage cavity, thereby increasing the temperature of the heavy oil in the first storage cavity to the first temperature. Through the above method, the temperature of the heating medium can be fully utilized to perform gradient heating on the heavy oil in the partition tank 2 and the heavy oil in the heavy oil storage tank 1, ensuring that the heavy oil in the heavy oil storage tank 1 is not in a solidified state, so that the heavy oil can flow into the partition tank 2, and the heavy oil in the partition tank 2 has a higher temperature and stronger fluidity, which is convenient for the fuel transfer pump 5 to pump. In this embodiment, the first temperature is 22 °C and the second temperature is 45 °C. Through the above method, the heating amount is reduced, and low energy consumption and low carbon emissions of the ship are achieved.
[0038] In some embodiments, the first pipeline 31 and the second pipeline 32 can also be arranged separately, so as to facilitate the precise control of the temperature of the compartment 2 and the heavy oil storage tank 1. Of course, the heating component 3 can also adopt a heater, and no excessive limitation is made here.
[0039] In some embodiments, both the first pipeline 31 and the second pipeline 32 are arranged in a serpentine shape. By the above method, the heat exchange area between the first pipeline 31 and the second pipeline 32 and the heavy oil can be increased, so that the heavy oil can be quickly heated.
[0040] In some embodiments, the arrangement spacing of the first pipeline 31 in the first storage cavity is greater than the arrangement spacing of the second pipeline 32 in the second storage cavity. Through the above setting, the heavy oil located in the compartment 2 can be quickly heated by the second pipeline 32, and then the heavy oil in the heavy oil storage area tank can be heated by the waste heat of the heating medium. Moreover, the temperature of the heavy oil located in the compartment 2 and the temperature of the heavy oil located in the heavy oil storage tank 1 can be accurately controlled.
[0041] In some embodiments, a temperature control valve 4 is arranged at the heating medium inlet of the second pipeline 32, and the probe 41 of the temperature control valve 4 is located in the second storage cavity. The temperature of the heavy oil in the second storage cavity is monitored in real time through the probe 41. When the temperature of the heavy oil is lower than the second temperature value, the temperature control valve 4 is opened, so that the heating medium enters the second pipeline 32 to quickly heat the heavy oil located in the second storage cavity. When the temperature of the heavy oil is higher than the second temperature value, the temperature control valve 4 is closed, thereby reducing heat consumption and further reducing the energy consumption of the ship.
[0042] In some embodiments, at least one communication hole communicating with the first storage cavity is opened on the cabin wall of the compartment 2. In this embodiment, three communication holes are opened on the cabin wall of the compartment 2. By opening the communication holes and reasonably designing the aperture of the communication holes, it can be ensured that the heavy oil located in the heavy oil storage tank 1 smoothly enters the compartment 2 under the action of gravity.
[0043] In some embodiments, a temperature detection device is arranged in the heavy oil storage tank 1, and the temperature detection device is used to detect the temperature of the heavy oil in the first storage cavity. In this embodiment, the temperature detection device is a thermometer. By setting the temperature detection device, the temperature of the heavy oil in the first storage cavity can be monitored in real time. The crew can know the temperature of the heavy oil in the first storage cavity through the temperature detection device, which is convenient for the crew to understand the situation in time. In other embodiments, the temperature detection device can adopt a temperature detection probe 41, and the temperature detected by the temperature detection probe 41 is transmitted to the electronic temperature display, which can also play the role of detection and is convenient for the crew to view.
[0044] In some embodiments, the fuel supply assembly 6 includes a sedimentation tank 61, a purifier 62, a daily-use tank 63, and a fuel supply unit 64 that are connected in sequence. The fuel transfer pump 5 is connected to the sedimentation tank 61, and the fuel supply unit 64 is connected to the end-user equipment 7. The heavy oil is sedimented in the sedimentation tank 61, so that the oil sludge settles to the bottom of the sedimentation tank 61. The heavy oil without oil sludge enters the daily-use tank 63 for storage after being separated and purified by the purifier 62, and finally is supplied to the end-user equipment 7 for use through the fuel supply unit 64.
[0045] In some embodiments, a first heater 611 is provided in the sedimentation tank 61, a second heater 621 is provided in the purifier 62, a third heater 631 is provided in the daily-use tank 63, and a fourth heater 641 is provided in the fuel supply unit 64. Through the above settings, it is possible to effectively heat the sedimentation tank 61, the purifier 62, the daily-use tank 63, and the fuel supply unit 64, so as to ensure that the fluidity of the heavy oil meets the requirements and can be smoothly supplied to the end-user equipment 7 for use.
[0046] This embodiment also provides a ship, which includes a hull and the above fuel storage and supply system. The fuel storage and supply system is arranged in the hull, which can reduce the energy consumption of the ship and improve the economy.
[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
