[0040] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0041] Methanol as a fuel for ships can reduce emissions of nitrogen oxides, sulfur oxides and particulate matter.

[0042] However, during the process of transporting methanol from the daily tank to the main engine through the methanol supply pipeline, a certain amount of methanol will remain in the pipeline, causing fuel loss. The methanol remaining in the pipeline also brings certain safety risks.

[0043] In order to solve the technical problem that methanol may remain in the methanol supply pipeline, the first embodiment of the present application provides a methanol collection device. Figure 1The methanol collecting device is used to collect methanol in the methanol supply pipeline. The methanol collecting device includes a purge pipeline 700, a collecting device 100, a pumping device 200, a first pipeline 300, a pressure regulating valve 310, a first shut-off valve 320, a second pipeline 400 and a second shut-off valve 410; the collecting device 100 is connected to the purge pipeline 700, and the collecting device 100 has a first liquid outlet 1111 and an exhaust port 1114; the pumping device 200 is connected to the first liquid outlet 1111 to guide the collecting device to The methanol in the device 100; the first pipeline 300 is connected to the collecting device 100; the pressure regulating valve 310 is arranged on the first pipeline 300, and the pressure regulating valve 310 is used to limit the pressure in the first pipeline 300; the first shut-off valve 320 is arranged on the first pipeline 300, and the first shut-off valve 320 is used to open or close the first pipeline 300; the second pipeline 400 is connected to the collecting device 100; the second shut-off valve 410 is arranged on the second pipeline 400, and the second shut-off valve 410 is used to open or close the second pipeline 400.

[0044] In some embodiments, the methanol collection device includes a generator purge line and a main engine purge line. The generator purge line is used to purge the fuel line that supplies methanol to the generator, and the main engine purge line is used to purge the fuel line that supplies methanol to the main engine. Both purge lines are used to clean the residual methanol in the methanol fuel line, and both purge lines are connected to the collection device 100 to introduce the cleaned methanol into the collection device 100.

[0045] In some embodiments, the first liquid outlet 1111 of the collecting device 100 is used to discharge at least part of the liquid methanol in the collecting device 100 , and the exhaust port 1114 is used to discharge the gaseous methanol inside the collecting device 100 .

[0046] In some embodiments, the pumping device 200 is used to provide power for the liquid methanol so that the liquid methanol can flow toward the methanol day tank. Specifically, the suction port of the pumping device 200 is connected to the first liquid outlet 1111 to draw in the liquid methanol, and the discharge port of the pumping device 200 is connected to the methanol day tank to pump the liquid methanol into the methanol day tank to achieve methanol recovery.

[0047] In some embodiments, the first pipeline 300 and the second pipeline 400 are respectively used to introduce an inert gas. In some embodiments, the inert gas is nitrogen, that is, the first pipeline 300 and the second pipeline 400 are respectively connected to a nitrogen generator and are respectively used to introduce nitrogen into the collection device 100.

[0048] In some embodiments, at least one of the first stop valve and the second stop valve is in a closed state, that is, at least one of the first pipeline 300 and the second pipeline 400 is closed. In other words, the first pipeline 300 and the second pipeline 400 cannot be opened at the same time.

[0049] In some embodiments, before pumping device 200 provides power to discharge the liquid methanol, it is necessary to inject nitrogen into collection device 100. The pump in pumping device 200 is a diaphragm pump, and normal operation of the diaphragm pump requires maintaining a certain pressure at the suction port. In the above embodiment, pressure regulating valve 310 in first pipeline 300 is used to maintain a pressurized environment in the portion of first pipeline 300 downstream of pressure regulating valve 310 and connecting collection device 100 and first pipeline 300 during the process of injecting nitrogen into collection device 100. This maintains ideal operating conditions for pumping device 200 and improves the reliability of the methanol collection equipment.

[0050] In some embodiments, the interior of the methanol collection device 100 needs to be inerted before use, i.e., nitrogen is replaced within the collection device 100. In the above embodiment, by providing a second pipeline 400 connected in parallel with the first pipeline 300 and not including a pressure regulating valve 310, specifically for nitrogen replacement within the collection device 100, the inerting of the interior of the collection device 100 can be more thorough, allowing for the maximum possible removal of air and water vapor from the interior of the collection device 100, thereby improving the safety of the methanol collection device.

[0051] In the above embodiment, the methanol collection device collects residual methanol removed from the purge line 700 via the collection device 100, thereby reducing methanol loss and improving the safety of the methanol fuel line. Furthermore, the methanol collection device 100, by providing a first pipeline 300, enables the collection device to fill the drainage device 100 with nitrogen before draining. This prevents negative pressure from forming within the collection device 100 during operation of the pumping device 200, thereby improving the reliability of the drainage of the collection device 100. The second pipeline 400 allows nitrogen to bypass the pressure regulating valve 310 during nitrogen replacement, fully inerting the interior of the collection device 100 and improving safety.

[0052] In some embodiments, see Figure 1 The collection device 100 includes a collection tank 110 and a filter assembly 120. The collection tank 110 is connected to the purge pipeline 700, the first pipeline 300 and the second pipeline 400. The collection tank 110 has a first liquid outlet 1111 and a first gas outlet 1112. The filter assembly 120 is connected to the first gas outlet 1112 and has a second gas outlet 1211. The filter assembly 120 is used to filter methanol in the inert gas.

[0053] Specifically, the gas in the collection tank 110 can enter the filter assembly 120 through the first gas outlet 1112. The filter assembly 120 is used to separate nitrogen and methanol. The filter element in the filter assembly 120 can not only filter liquid methanol, but also adsorb gaseous methanol to separate nitrogen and methanol. The separated nitrogen is discharged from the filter assembly 120 through the second gas outlet 1211.

[0054] In the above embodiment, the liquid methanol injected into the collection tank 110 through the purge line 700 is stored in the collection tank 110, realizing the first collection of methanol; part of the methanol and nitrogen enter the filter component 120 through the first gas outlet 1112, and the methanol and nitrogen are separated in the filter component 120. The nitrogen leaves the filter component 120 through the second gas outlet 1211, and the methanol is retained in the filter component 120 to realize the second collection of methanol. The two collections of the collection tank 110 and the filter component 120 can further reduce the loss of methanol and improve the collection efficiency of the methanol collection equipment.

[0055] In some embodiments, see Figure 2 The collecting tank 110 includes a first tank body 111 and a gas-liquid separator 112. The first tank body 111 has a first accommodating chamber 1113, a first liquid outlet 1111 and a first gas outlet 1112. The first liquid outlet 1111 and the first gas outlet 1112 are connected to the first accommodating chamber 1113, and the purge line 700, the first line 300 and the second line 400 are connected to the first accommodating chamber 1113; the gas-liquid separator 112 is arranged in the first accommodating chamber 1113 and is connected to the first tank body 111. The outlet of the purge line 700 faces the gas-liquid separator 112.

[0056] Specifically, the purge pipeline 700 can spray gas or liquid toward the gas-liquid separator 112 , and part of the gaseous methanol contacts the gas-liquid separator 112 with a lower temperature and is condensed and liquefied into liquid methanol.

[0057] In the above embodiment, the gas-liquid separator 112 is provided in the first tube body to improve the efficiency of the collection tank 110 in collecting methanol, reduce the pressure of the filter assembly 120, and extend the service life of the filter assembly 120.

[0058] In some embodiments, see Figure 2 The gas-liquid separator 112 has a third accommodating chamber 1121, and the third accommodating chamber 1121 forms an opening 1122 on the gas-liquid separator 112. The purge pipeline 700 is passed through the opening 1122. The third accommodating chamber 1121 is connected to the outlet of the purge pipeline 700. The gas-liquid separator 112 also has a through hole 1123, which connects the first accommodating chamber 1113 and the third accommodating chamber 1121.

[0059] Specifically, part of the purge pipeline 700 is inserted into the third accommodating chamber 1121, and the liquid methanol in the third accommodating chamber 1121 can flow to the first accommodating chamber 1113 through the through hole 1123. In other words, the gas-liquid separation component 112 with the third accommodating chamber 1121 is covered at the outlet of the purge pipeline 700.

[0060] In the above embodiment, the outlet of the purge line 700 is located in the third accommodating chamber 1121 to increase the possibility of the gaseous methanol ejected from the purge line 700 contacting the gas-liquid separator 112, thereby further improving the efficiency of the collection tank 110 in collecting methanol in one go.

[0061] In some embodiments, the methanol collection device includes multiple purge pipes 700, namely a first purge pipe 710 and a second purge pipe 720; the collection tank 110 includes multiple gas-liquid separators 112, namely a first gas-liquid separator 1124 and a second gas-liquid separator 1125, the first purge pipe 710 is passed through the opening 1122 of the first gas-liquid separator 1124, and the second purge pipe 720 is passed through the opening 1122 of the second gas-liquid separator 1125.

[0062] In some embodiments, the first purge line 710 is used to purge the methanol fuel line of the generator, and the second purge line 720 is used to purge the methanol fuel line of the host. In some embodiments, the purge line 700 includes two first purge lines 710 .

[0063] In some embodiments, the two first purge lines 710 are disposed through the opening 1122 of the same first gas-liquid separator 1124 .

[0064] In the above embodiment, due to the obstruction of the first and second separators, the flow rates of the gas and liquid ejected from the first purge line 710 and the second purge line 720 are reduced. The first separator can reduce the possibility of the gas and liquid ejected from the first purge line 710 entering the second purge line 720, and also reduce the possibility of the gas and liquid ejected from the second purge line 720 entering the first purge line 710. Similarly, the second separator can reduce the possibility of the gas and liquid ejected from the second purge line 720 entering the first purge line 710, and also reduce the possibility of the gas and liquid ejected from the first purge line 710 entering the second purge line 720. This reduces the possibility of methanol being retained in the purge line 700, further improving the methanol collection efficiency of the collection device 100, and also improving the safety performance of the methanol collection equipment.

[0065] In some embodiments, see Figure 3The filter assembly 120 includes a second tank body 121 and a filter element 122. The second tank body 121 has a second accommodating chamber 1212. The second air outlet 1211 is arranged on the second tank body 121 and is connected to the second accommodating chamber 1212. The filter element 122 divides the second accommodating chamber 1212 into a first sub-chamber 1213 and a second sub-chamber 1214. The second air outlet 1211 is connected to the first sub-chamber 1213, and the first air outlet 1112 is connected to the second sub-chamber 1214.

[0066] In some embodiments, filter element 122 is a carbon fiber filter element; in other embodiments, filter element 122 is a glass fiber filter element; in still other embodiments, filter element 122 is a composite filter element of carbon fiber and glass fiber. Composite filter elements can not only filter liquid methanol but also absorb gaseous methanol, thereby improving the filtering effect of filter element 122.

[0067] In the above embodiment, due to the presence of filter element 122, liquid methanol enters second sub-chamber 1214 from first gas outlet 1112, is filtered by filter element 122, and flows to the bottom of second sub-chamber 1214, while gaseous methanol is adsorbed by filter element 122. Nitrogen, on the other hand, can pass through filter element 122 via second sub-chamber 1214 and into first sub-chamber 1213, and then exit filter assembly 120 via second gas outlet 1211. This makes the emissions from the methanol collection device more environmentally friendly and in compliance with emission standards, while also improving the collection efficiency of the methanol collection device.

[0068] In some embodiments, please refer again to Figure 1 , the second sub-chamber 1214 is connected to the pumping device 200.

[0069] In the above embodiment, by connecting the pumping device 200 and the second sub-cavity 1214, the pumping device 200 can not only transport the methanol in the collection tank 110 to the methanol daily tank, but also transport the methanol in the filter assembly 120 to the methanol daily tank, thereby improving the recovery efficiency of the methanol after collection.

[0070] In some embodiments, please refer again to Figure 3 The second tank body 121 has a second liquid outlet 1215, which is connected to the second sub-cavity 1214. The collection device 100 also includes a cache tank 130, which is connected to the second liquid outlet 1215 and the pumping device 200 respectively.

[0071] It can be understood that, since the collection tank 110 is able to collect most of the methanol in the purge line 700 , the amount of methanol collected for the second time by the filter assembly 120 is relatively small.

[0072] In some embodiments, the first sub-chamber 1213 is further provided with a conical cover, which is connected to the second tank body 121. The conical cover has a first opening and a second opening, and the flow cross-sectional area of ​​the first opening is larger than the flow cross-sectional area of ​​the second opening. The conical cover is used to guide the liquid methanol so that the liquid methanol flows to the second liquid outlet 1215 under the action of gravity and the conical cover. In addition, the gas entering the filter assembly 120 from the first gas outlet 1112 passes through the conical cover to reach the filter element 122. In the process of passing through the first opening and the second opening, the flow rate of the gas is reduced, which can reduce the impact of the gas impacting the filter element 122 on the filter element 122, thereby extending the life of the filter element 122 and reducing the maintenance frequency of the filter element 122.

[0073] In some embodiments, a fifth stop valve and a liquid level sensor are provided between the collection tank 110 and the pumping device 200. When the methanol liquid level in the buffer tank 130 reaches a preset height, the liquid level sensor can sense and open the fifth stop valve to connect the pipeline between the buffer tank 130 and the pumping device 200.

[0074] In the above embodiment, a buffer tank 130 is provided to temporarily store the methanol filtered out of the filter assembly 120. When the amount of methanol temporarily stored in the buffer tank 130 reaches a certain amount, the pumping device 200 is used for unified pumping, thereby reducing the number of times the pumping device 200 is opened, thereby extending the service life of the pumping device 200.

[0075] In some embodiments, see Figure 1 The methanol collection equipment also includes a collection pipeline 500, which connects the first liquid outlet 1111, the second liquid outlet 1215 and the pumping device 200; the pumping device 200 includes a first pump 211, a third stop valve 212, a second pump 221, a fourth stop valve 222, a first branch 210 and a second branch 220, the first pump 211 and the third stop valve 212 are arranged on the first branch 210, the third stop valve 212 is used to open or close the first branch 210, the second pump 221 and the fourth stop valve 222 are arranged on the second branch 220, and the fourth stop valve 222 is used to open or close the first branch 210; the first branch 210 and the second branch 220 are connected to the collection pipeline 500.

[0076] In some embodiments, one of the first branch 210 and the second branch 220 is in communication with the collection pipeline 500, that is, at most one of the first pump 211 and the second pump 221 is in communication with the collection pipeline 500. Specifically, when the third shut-off valve 212 opens the first branch 210, the fourth shut-off valve 222 closes the second branch 220; when the fourth shut-off valve 222 opens the second branch 220, the third shut-off valve 212 closes the first branch 210.

[0077] In the above embodiment, the first branch 210 including the first pump 211 and the second branch 220 including the second pump 221 are connected in parallel, so that the first pump 211 and the second pump 221 serve as backup pumps for each other, thereby improving the reliability of the pumping device 200.

[0078] In some embodiments, a check valve is further provided in the first branch 210 and the second branch 220 respectively to prevent the methanol in the methanol daily tank from flowing into the collection pipeline 500 .

[0079] In some embodiments, the pumping device 200 further includes a basket filter, and the liquid inlets of the first pump 211 and the second pump 221 are respectively connected to basket filters to filter the liquid inlets of the first pump 211 and the second pump 221 to extend the service life of the pumping device 200.

[0080] In some embodiments, pressure sensors are provided at the inlet and outlet of the basket filter respectively to detect the pressure drop of the basket filter, thereby back-purging or replacing the basket filter, thereby improving the reliability of the pumping device 200.

[0081] In some embodiments, the first liquid outlet 1111 and the buffer tank 130 are respectively connected to the collection pipeline 500 to transport the collected methanol to the methanol daily tank through the collection pipeline 500 and the pumping device 200.

[0082] In some embodiments, see Figure 1 The methanol collection equipment also has an exhaust pipeline 600, the exhaust pipeline 600 has an air inlet 610, the collection tank 110 has the exhaust port 1114, the exhaust port 1114 and the second air outlet 1211 are connected to the air inlet 610 of the exhaust pipeline 600; wherein, the collection device 100 also includes a safety valve 140, the safety valve 140 is connected to the exhaust port 1114 and the exhaust pipeline 600.

[0083] In the above embodiment, exhaust line 600 is provided to discharge gas from collection tank 110 and filter assembly 120, and a shared vent port facilitates connection to external equipment or pipelines.
