[0034] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0035] The purpose of the embodiment of the present application is to provide a methanol fuel filling station. Figure 1-Figure 3 As shown, the methanol fuel skid-mounted filling station includes a filling station oil pan 1, an injection pipe 2, a steam recovery pipe 4, an inert gas pipe 3, a fire-fighting pipe 9, a fire-fighting pipe 9 bracket 8 and a control box 13.

[0036] The oil pan 1 of the filling station is a box-shaped structure with a grille on top for easy operation. The oil pan 1 of the filling station is used to store methanol fuel leaked during the filling process and is made of high-strength steel to ensure a stable and durable structure.

[0037] As an optional embodiment, the methanol fuel skid-mounted filling station further includes a discharge pipe 15 and a three-way valve 14 .

[0038] One end of the discharge pipe 15 is connected to the filling station oil pan 1 and communicates with the inside thereof, and the other end is connected to the methanol fuel discharge tank and communicates with the inside thereof. The three-way valve 14 is arranged on the pipeline between the discharge pipe 15 and the methanol fuel discharge tank, and is used to change the direction of the liquid discharged from the filling station oil pan 1.

[0039] Specifically, by adjusting the opening direction of the three-way valve 14 on the discharge pipe 15, different liquids are discharged separately, the leaked methanol fuel is guided into the methanol fuel discharge tank, and the rainwater is directly discharged to the side.

[0040] In addition, a filter 11 is provided between the injection pipe 2 and the methanol fuel tank for filtering impurities in the methanol fuel, and the filter 11 is installed on the filling station oil pan 1 through the filter 11 base. The filter 11 base is connected to the filter 11 by bolts, and the filter 11 base is connected to the filling station oil pan 1 by welding.

[0041] The injection pipe 2 is provided on the oil pan 1 of the filling station, and is used to add methanol fuel into the methanol fuel tank. One end of the injection pipe 2 is connected to the shore-based hose 10. Specifically, a support base 5 is provided on the oil pan 1 of the filling station, and the injection pipe 2 is mounted on the support base 5 through a first support 6. The support base 5 and the first support 6 are connected by bolts, and the support base 5 provides strong support to the first support 6.

[0042] Specifically, in the axial direction of the injection pipe 2, the first bracket 6 is connected to the flange at the end of the injection pipe 2 by bolts to form a whole; in the radial direction of the injection pipe 2, the first bracket 6 is connected to the bracket base 5 by bolts to support the load of the injection pipe 2 and bear the impact forces from different directions.

[0043] As an optional embodiment, the methanol fuel skid filling station further includes a saddle 16, which is arranged on the oil pan 1 of the filling station and is used to support and guide the shore-based hose 10. The support and guiding functions of the saddle 16 and the stability of the connection method ensure the stability of the filling station and reduce the occurrence of accidents. Among them, the upper part of the saddle 16 is a smooth curved surface, and the lower part is connected to the oil pan 1 of the filling station, so as to provide the shore-based hose 10 with necessary support and bear the impact force in all directions.

[0044] The vapor recovery pipe 4 is arranged on the oil pan 1 of the filling station, and is used to recover the mixed gas of methanol vapor and inert gas in the cabin. A second bracket 7 is arranged on the oil pan 1 of the filling station, and the second bracket 7 is used to install the vapor recovery pipe 4.

[0045] The support base 5 and the second support 7 are all welded to the filling station oil pan 1. A third support is also provided on the filling station oil pan 1 to support the steam recovery pipe 4. The second support 7 and the third support jointly support the load of the steam recovery pipe 4 and bear the impact forces from different directions.

[0046] The inert gas pipe 3 is arranged between the injection pipe 2 and the steam recovery pipe 4, and is used to replenish the methanol fuel tank with inert gas and purge the injection pipe 2 and the steam recovery pipe 4 after the methanol fuel is filled.

[0047] The fire-fighting pipe 9 is arranged on the oil pan 1 of the filling station through a fire-fighting pipe 9 bracket 8, and the fire-fighting pipe 9 bracket 8 is used to support the load of the fire-fighting pipe 9. The fire-fighting pipe 9 bracket 8 is welded to the oil pan 1 of the filling station.

[0048] Specifically, the fire-fighting pipe 9 bracket 8, bracket base 5, second bracket 7 and third bracket are connected to form a whole, supporting the load of the fire-fighting pipe 9 and the impact force generated during operation. It is also a carrier of the bracket of the inert gas pipe 3 and provides support for the control box 13 mounted on the side.

[0049] The control box 13 is an important part of the entire filling station instrument display and control of the filling process, as well as ship-shore communication. The control pipelines and instruments of the entire filling station are integrated and arranged inside, and a ship-shore communication interface and emergency operation buttons are provided. The control box 13 is arranged on the fire pipe 9 bracket 8, and is used to communicate with the ship and the shore to control the filling process of methanol fuel and ensure automatic switching during the filling process of methanol fuel.

[0050] This application reduces the layout space of the filling station pipeline, improves the construction environment, and provides technical support for the transformation of existing methanol fuel ships. In addition, the combination of the fire pipe 9 bracket 8, the first bracket 6 and the second bracket 7 realizes the bracket unit design, which is simple to construct and offsets the external force impact during the filling process, making it more reliable to use.

[0051] Before refueling the methanol fuel tank on board the ship, it is necessary to check the integrity and safety of the oil pan 1 and related facilities of the filling station, ensure that the fire pipe 9 and the control box 13 are working properly, and prepare the shore-based hose 10 and inert gas supply facilities.

[0052] Next, connect one end of the shore-based hose 10 to the injection pipe 2 on the oil pan 1 of the filling station, and ensure the hose is firmly connected through the saddle 16. Then, open the control box 13 to ensure that it communicates with the ship and shore. Prepare the cabin on the ship side to receive methanol fuel.

[0053] The valve of the injection pipe 2 is opened to start filling the ship with methanol fuel. At the same time, inert gas is added through the inert gas pipe 3 to ensure safety during the filling process. During the filling process, the filling speed and pressure are monitored by the control box 13 to ensure that the filling process proceeds smoothly.

[0054] During the filling process, regularly check the oil pan 1 and the connecting pipelines of the filling station to ensure that there is no leakage. If leakage occurs during the filling of methanol fuel, immediately close the corresponding valve and handle it through the fire pipe 9 and the control box 13, and use the discharge pipe 15 and the three-way valve 14 to guide the leaking liquid to the discharge tank.

[0055] When the filling is completed, close the valve of the injection pipe 2 and the control box 13. Disconnect the shore-based hose 10 and clean the pipeline through the inert gas pipe 3. Finally, clean and maintain the oil pan 1 and related facilities of the filling station, and record the data and conditions during the filling process for subsequent analysis and reference.

[0056] In this application, the fire pipe 9 and the control box 13 ensure safety during the filling process, and the discharge pipe 15 and the three-way valve 14 can handle leakage in time. The structural design of the oil pan 1 of the filling station makes the operation easier, and the facilities for connecting the pipelines make the filling process smoother. The setting of the steam recovery pipe 4 and the inert gas pipe 3 helps to recover and treat harmful gases, and the filter 11 can filter out impurities to ensure the quality of the methanol fuel filled.
