Description

Technical Field

[0001] This invention relates to the field of cruise ship fuel tank conversion technology, and in particular to a cruise ship fuel storage system. Background Technology

[0002] Large cruise ships typically have global deployment capabilities, and their routes are highly variable. Different routes and ports have different emission requirements. Therefore, the proportion of fuel required for different routes varies considerably.

[0003] Disadvantages of existing technology:

[0004] 1. Cruise ships have dedicated fuel tanks, and each tank can only hold one type of fuel.

[0005] 2. It is difficult to meet the changing oil quality requirements of different routes. Summary of the Invention

[0006] In view of the above-mentioned problems existing in the prior art, the present invention provides a cruise ship oil storage system, which can solve the problem that cruise ships may need to carry different types of oil when sailing on different routes and docking at different ports, and need to change the oil stored in the oil tanks. This allows the cruise ship's oil tanks to be suitable for carrying multiple types of oil, rather than only being able to carry a single type of oil, thereby improving the cruise ship's adaptability to the emission requirements of different ports, and at the same time meeting the needs of different routes for changing oil types.

The other end extends into the variable oil storage tank for oil unloading.

[0044] Heating system 18 is used to heat the variable oil storage tank when storing oil with a viscosity higher than the set viscosity in the variable oil storage tank.

[0045] Valves are provided on the first sub-wash tank pipe 6, the second sub-wash tank pipe 7, the first sub-sweep tank pipe 10, the second sub-sweep tank pipe 11, the first sub-inlet pipe 13, the second sub-inlet pipe 14, the first sub-outlet pipe 16, the second sub-outlet pipe 17, and the heating system 18.

[0050] When the first type of oil is unloaded, only the first sub-unloading pipe 16 is opened, and the first type of oil is unloaded from the oil storage tank through the first oil unloading main pipe 2 and the first sub-unloading pipe 16. At this time, the valves on the first sub-washing pipe 6, the second sub-washing pipe 7, the first sub-sweeping pipe 10, the second sub-sweeping pipe 11, the first sub-inlet pipe 13, the second sub-inlet pipe 14 and the second sub-unloading pipe 17 are all in the closed state.

[0051] If a second type of oil needs to be transferred into the variable oil storage tank after the first type of oil has been removed, the variable oil storage tank shall be cleaned, specifically including:

[0052] Close the valves on the second sub-wash pipe 7, the second sub-sweep pipe 11, the first sub-inlet pipe 13, the second sub-inlet pipe 14, the first sub-outlet pipe 16, and the second sub-outlet pipe 17. Only open the valve on the first sub-wash pipe 6 to connect it to the first oil import main pipe 1, and open the valve on the first sub-sweep pipe 10 to connect it to the first oil export main pipe 2. At the same time, use the first type of oil to wash and sweep the variable oil storage tank. After the washing and sweeping are completed, introduce the second type of oil, which is different from the first type of oil.

[0053] In this embodiment, if a second type of oil is to be introduced, only the second sub-introduction pipe 14 is opened, and the second type of oil is introduced into the variable oil storage tank through the second oil introduction main pipe 3 and the second sub-introduction pipe 14. At this time, the valves on the first sub-washing pipe 6, the second sub-washing pipe 7, the first sub-sweeping pipe 10, the second sub-sweeping pipe 11, the first sub-introduction pipe 13, the first sub-outtroduction pipe 16 and the second sub-outtroduction pipe 17 are all in the closed state.

[0054] When the second type of oil is unloaded, only the second sub-unloading pipe 17 is opened. The second type of oil is unloaded from the oil storage tank through the second oil unloading main pipe 4 and the second sub-unloading pipe 17. At this time, the valves on the first sub-washing pipe 6, the second sub-washing pipe 7, the first sub-sweeping pipe 10, the second sub-sweeping pipe 11, the first sub-inlet pipe 13, the second sub-inlet pipe 14 and the first sub-unloading pipe 16 are all in the closed state.

[0055] If, after removing the second type of oil, it is necessary to transfer the first type of oil into the variable oil storage tank, the variable oil storage tank shall be cleaned, specifically including:

[0056] Close the valves on the first sub-wash pipe 6, the first sub-sweep pipe 10, the first sub-inlet pipe 13, the second sub-inlet pipe 14, the first sub-outlet pipe 16, and the second sub-outlet pipe 17. Only open the valve on the second sub-wash pipe 7 to connect it to the second oil import main pipe 3, and open the valve on the second sub-sweep pipe 11 to connect it to the second oil export main pipe 4. At the same time, use the second type of oil to wash and sweep the variable oil storage tank. After the washing and sweeping are completed, the first type of oil is introduced.

[0057] In this embodiment, the heating system 18 includes a steam heating coil located in the bottom area of ​​the variable oil storage tank. When using the heating system 18, the shut-off valve on the steam heating coil is opened to heat the variable oil storage tank.

[0058] If the viscosity of the oil stored in the variable oil storage tank is lower than the set viscosity, then close the shut-off valve on the steam heating coil.

[0059] In some embodiments of the present invention, the portion of the tank washing pipe 5 extending into the variable oil storage tank is located in the top area of ​​the variable oil storage tank, and multiple tank sweeping devices are arranged in a matrix inside the variable oil storage tank to spray the originally stored oil to wash and sweep the inside of the variable oil storage tank. The spraying direction of the multiple tank sweeping devices covers the inner wall, bottom surface and bottom corner area of ​​the variable oil storage tank.

[0060] In this embodiment, the portion of the tank washing pipe 5 that extends into the variable oil storage tank may include multiple parallel sub-tank washing pipes 5, and each sub-tank washing pipe 5 is provided with at least one tank cleaning device. At the same time, each sub-tank washing pipe 5 is provided with a pressure stabilizing valve at the end connected to the tank washing pipe 5, so that the oil pressure in each sub-tank washing pipe 5 is equal.

[0061] Furthermore, the tank cleaning pipe 5 may be equipped with a throttle valve on the section of the pipe near the oil storage tank to adjust the flow rate of the oil in the tank cleaning pipe 5, so as to change the spray speed of the oil sprayed through the tank cleaning device.

[0062] In some embodiments of the present invention, the portion of the dispensing pipe 15 extending into the variable oil storage tank is located at the bottom region of the variable oil storage tank and forms an inverted funnel-shaped suction port for adsorbing oil at the bottom, thereby increasing the area for adsorbing oil. At the same time, a recessed region is formed in the variable oil storage tank, which is the lowest region in the variable oil storage tank, so that the oil stored in the variable oil storage tank can eventually flow to the lowest region. The inverted funnel-shaped suction port of the dispensing pipe 15 extending into the variable oil storage tank corresponds to the lowest region for adsorbing oil.

[0063] In some embodiments of the present invention, the portion of the transfer pipe 12 extending into the variable oil storage tank is located on the side wall of the variable oil storage tank and in the upper-middle region of the overall height of the variable oil storage tank. Meanwhile, the port of the transfer pipe 12 may be arranged facing the side wall inside the variable oil storage tank so that the transferred oil can flow along the side wall into the variable oil storage tank after transfer.

[0064] As can be seen from the above technical solutions, the cruise ship oil storage system provided in the above embodiments of the present invention adopts a variable oil transfer system. When it is necessary to change the oil used, the tank sweeping system is used to sweep the tank of the variable oil using the original stored oil, and then the new oil is transferred in, so as to realize the transfer of variable oil in the same tank. At the same time, by adopting a variable oil sweeping system, the storage quality of each oil can be improved.

[0065] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
