Description

Technical Field

[0001] This application relates to the field of oil storage system technology, and in particular to a marine fuel oil storage system and a ship. Background Technology

[0002] Marine diesel engines are prone to abnormal wear of exhaust valve seats during operation. Generally, using fuel additives can solve the problem of abnormal wear when the sulfur concentration of the fuel is below 500ppm.

[0003] In related technologies, fuel additives are added to the fuel storage device in the fuel oil storage system. However, because marine diesel engines often return leaked oil to the fuel storage device for reuse, the fuel additives in the leaked oil also return, leading to an increase in the concentration of fuel additives in the fuel oil in the storage device. If the concentration of fuel additives exceeds a certain threshold, it can easily affect the turbine blades. Furthermore, it is difficult to monitor the concentration of fuel additives in the fuel oil using these related technologies. Utility Model Content

Detailed Implementation

[0038] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0039] This application provides a marine fuel oil storage system; please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is a top view of a marine fuel oil storage system provided in an embodiment of this application. Figure 2 This is a front view of a marine fuel oil storage system provided in an embodiment of this application.

[0040] The marine fuel oil storage system includes a fuel oil storage device 100, a filling device 200, a sampling platform 300, and a spectrometer 400. The fuel oil storage device 100 is equipped with an inlet pipe 101. The filling device 200 is in fluid communication with the fuel oil storage device 100 and is used to inject fuel additives into the fuel oil storage device 100. The sampling platform 300 is connected to the inlet pipe 101 through a detection branch pipe 103 and is used to collect fuel oil samples. The spectrometer 400 is positioned towards the sampling platform 300 and is used to monitor the concentration of fuel additives in the fuel oil samples in the sampling platform 300.

[0041] The spectrometer 400 determines the concentration of fuel additives in the sample by analyzing the spectrum of the sampled sample to determine the degree of light absorption. The spectrometer 400 can be positioned directly above the sampling stage 300, or above the sampling stage 300 and located on its outer periphery, with the light emitted by the light source of the spectrometer 400 directed towards the sampling stage 300. During sampling, the light emitted by the light source of the spectrometer 400 is aimed at the fuel sample, and the reflected light is received for detection.

[0042] like Figure 3 and Figure 4 As shown, Figure 3 This is a top view of the dispensing device 200 provided in the embodiments of this application. Figure 4 This is a top view of the dispensing device 200 provided in an embodiment of this application.

[0043] The refueling device 200 includes a storage tank 201, a refueling pipeline 202, a refueling branch 203, and a metering pump 204. The storage tank 201 stores fuel additives. One end of the refueling pipeline 202 is connected to the storage tank 201. The refueling branch 203 is connected to the end of the refueling pipeline 202 away from the storage tank 201. The metering pump 204 is connected between the refueling branch 203 and the fuel storage device 100. The metering pump 204 is connected to an outlet pipeline 210, which is connected to the fuel storage device 100.

[0044] The refueling pipeline 202 shall be provided in at least one set, and each set of refueling pipelines 202 shall be connected to one or more refueling branches 203. For example, if there is one set of refueling pipelines 202, one end of the refueling pipeline 202 shall be connected to one refueling branch 203; or if there is one set of refueling pipelines 202, one end of the refueling pipeline 202 shall be connected to two refueling branches 203; or if there are two sets of refueling pipelines 202, one end of the refueling pipeline 202 shall be connected to one refueling branch 203; or if there are two sets of refueling pipelines 202, one end of the refueling pipeline 202 shall be connected to two refueling branches 203. The number of refueling pipelines 202 and refueling branches 203 may be increased or decreased according to actual needs, and this application does not impose a specific limitation.

[0045] In one embodiment, the filling line 202 is provided in a set, with one end of the filling line 202 connected to two filling branches 203, each filling branch 203 corresponding to a metering pump 204. The two filling branches 203 allow one branch to be used for filling fuel additives, while the other serves as a backup. If one filling branch 203 becomes blocked or the metering pump 204 fails, the other branch can be used to fill fuel additives. Alternatively, the two filling branches 203 can be used to fill fuel additives into two different fuel storage devices 100 respectively.

[0046] The filling line 202 is connected to the bottom of the side wall of the storage tank 201, which allows all the fuel additive in the storage tank 201 to be used and avoids waste.

[0047] A filter 205 is installed on the refueling line 202 to filter the fuel additive. The filter 205 can be one of a T-type filter, a Y-type filter, a basket filter, or a cartridge filter; in one embodiment, the filter 205 is a Y-type filter. The filter 205 filters impurities in the fuel additive, preventing them from entering the fuel storage device 100.

[0048] A first valve 206 is installed on the filling line 202, and a second valve 207 is installed on the filling branch line 203. The opening and closing of the filling line 202 and the filling branch line 203 are controlled by the first valve 206 and the second valve 207, thereby controlling the delivery path of the fuel additive. The first valve 206 and the second valve 207 can be selected as solenoid valves.

[0049] A third valve 208 is installed at the connection between the metering pump 204 and the filling branch 203, and a fourth valve 209 is installed at the connection between the metering pump 204 and the outlet pipeline 210. The third valve 208 can be a shut-off valve. As the core actuator, the metering pump 204 is responsible for accurately delivering additives according to PLC instructions. Long-term operation may require maintenance or replacement due to pump core wear and seal aging. The shut-off valve can cut off the connection between the filling branch 203 and the metering pump 204, ensuring no medium flow within the metering pump 204 after closure, facilitating maintenance and replacement. The fourth valve 209 can be a check valve. When the metering pump 204 starts and stops, the outlet pipeline 210 experiences a water hammer effect, causing reverse flow. The check valve prevents backflow of fuel in the outlet pipeline 210 due to pressure difference when the metering pump 204 stops working, ensuring unidirectional delivery of fuel additives and maintaining the accuracy of fuel additive concentration control.

[0050] One end of the outlet pipe 210 is connected to a connector 211, and the fuel storage device 100 is provided with a connector interface 104 for connecting to the connector 211. In one embodiment, the outlet pipe 210 is a flexible hose, such as a rubber hose. The flexible hose can adjust the position of the connector 211, facilitating the connection between the connector 211 and the fuel storage device 100, while also simplifying the pipeline design and facilitating installation and maintenance. The connector 211 and the connector interface 104 are detachably connected. For example, after the connector 211 is inserted into the connector interface 104, it is fixedly connected by a fastener or by a snap-fit ​​connection, which facilitates the insertion and fixation of the connector 211 and the connector interface 104 and makes replacement easy.

[0051] The refueling device 200 also includes a level gauge 212, which is disposed on the side wall of the storage tank 201. The level gauge 212 is used to detect the liquid level in the storage tank 201. The level gauge 212 can be a buoyancy level gauge, a differential pressure level gauge, or a direct-reading level gauge. In one embodiment, the level gauge 212 is a direct-reading level gauge, which can directly read the liquid level in the storage tank 201 by communicating with it. This application uses the level gauge 212 to measure the liquid level in the storage tank 201 to determine whether fuel additive needs to be added to the storage tank 201.

[0052] The filling device 200 also includes a base 213, a first support portion 216, and a second support portion 214. A storage tank 201, a filling pipeline 202, and a metering pump 204 are fixedly mounted on the base 213. The first support portion 216 is disposed on the base 213 and supports the filling pipeline 202. The second support portion 214 is disposed on the base 213 and adjacent to the first support portion 216, and supports the metering pump 204. In one embodiment, the metering pump 204 is fixedly mounted on the base 213 via the first support portion 216, and the filling pipeline 202 is fixedly mounted on the base 213 via the second support portion 214. The storage tank 201 is fixedly connected to the base 213 by fasteners such as bolts, the metering pump 204 is fixedly connected to the first support portion 216 by fasteners such as bolts, and the first support portion 216 is fixedly connected to the base 213 by fasteners such as bolts, thus achieving a stable fixation of the metering pump 204. The filling pipe 202 passes through the second support part 214. The filling pipe 202 is fixedly connected to the base 213 by fasteners such as bolts, so as to fix the filling pipe 202 and prevent the filling pipe 202 from directly contacting the base 213, which is suitable for the relatively turbulent environment on the ship.

[0053] The filling device 200 also includes a PLC controller 215, which is electrically connected to the flow meter 102, the metering pump 204, the first valve 206, the second valve 207, and the spectrometer 400.

[0054] In one embodiment, the concentration range of the fuel additive in the fuel storage device 100 is 250-350 ppm. If the concentration is below the range, it is difficult to form an effective anti-wear layer, and if the concentration is above the range, it will have an adverse effect on the gas turbine blades. Therefore, it is necessary to control the concentration of the fuel additive.

[0055] The fuel additive is a mixture of potassium docusate and 200# aliphatic hydrocarbons. It contains almost no potassium in the fuel in the fuel storage device 100 and during the operation of the diesel engine. After the fuel additive is added, the potassium can be detected by the spectrometer 400.

[0056] In one embodiment, the spectrometer 400 is an EDX1800B portable energy-dispersive X-ray fluorescence spectrometer, which can monitor concentrations as low as 1 ppm to monitor potassium in fuel, thereby enabling the monitoring of fuel additive concentrations in fuel.

[0057] Flow meter 102 detects the amount of fuel added to fuel storage device 100 in fuel inlet line 101. Flow meter 102 outputs a first flow signal to PLC controller 215. PLC controller 215 calculates the amount of fuel additive to be injected into fuel storage device 100. PLC controller 215 outputs a second flow signal to metering pump 204. Metering pump 204 draws fuel additive from storage tank and injects fuel additive into fuel storage device 100 through filling line 202, filling branch line 203 and outlet line 210. Spectrometer 400 analyzes the sample in sampling station 300. If the concentration of fuel additive in the sample is higher than the preset concentration range, the injection of fuel additive is suspended.

[0058] By monitoring the concentration of fuel additives, we can ensure their anti-wear effect while avoiding excessive fuel additives that could damage the equipment.

[0059] Meanwhile, the refueling device 200 of this application adopts a modular design, which eliminates the need for modification of the fuel storage device 100 during installation. Installation is completed simply by placing the refueling device 200 entirely on top of the fuel storage device 100 and connecting the outlet pipe 210 to the fuel storage device 100. This avoids the complex positioning of scattered components and does not damage the original ship deck or hull structure. The installation of the refueling device 200 does not affect the normal operation of the vessel, reducing costs. Furthermore, it is not dependent on the hull size or fuel pipeline layout of a specific ship type. Connection can be achieved by adjusting the angle of the refueling device 200 or the length of the outlet pipe 210, eliminating the need for custom design and improving the versatility of the refueling device 200.

[0060] Secondly, this application also provides a ship including the aforementioned marine fuel oil storage system.

[0061] like Figure 5 As shown, in one embodiment, the ship also includes a marine fuel tank 500 and a fuel engine 600. The marine fuel tank 500 is connected to a marine fuel storage system via a pipeline. A fuel transfer pump 700 is located between the marine fuel tank 500 and the marine fuel storage system. The marine fuel storage system is connected to the fuel engine 600 via a pipeline.

[0062] The filling device 200 detects the amount of fuel delivered by the fuel delivery pump 700, thereby calculating the amount of fuel additive to be added to the fuel storage device 100, and monitors the concentration of fuel additive in the fuel in the fuel storage device 100 by the spectrometer 400 to prevent the concentration of fuel additive from exceeding the concentration range.
