[0044] Methanol as a fuel for ships can reduce emissions of nitrogen oxides, sulfur oxides and particulate matter.

[0045] 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.

[0046] In some optional embodiments, a purge pipeline 1000 is provided on the vessel for purging the methanol supply pipeline to remove residual methanol in the methanol supply pipeline.

[0047] In order to solve the technical problem of high methanol loss rate caused by methanol residue in the methanol supply pipeline, this application provides a methanol collection device. Figure 1 、 Figure 2 and Figure 5The methanol collection device is used to collect methanol discharged from the purge pipeline 1000. The methanol collection device includes a collection device 2000, a filtering device 3000, an input pipeline 4000 and an output pipeline 5000. The collection device 2000 is connected to the purge pipeline 1000. The collection device 2000 includes a first tank body 2100 and a gas-liquid separator 2200. The first tank body 2100 has a first accommodating chamber 2120 connected to the purge pipeline 1000. The first tank body 2100 It has a first exhaust port 2130; the gas-liquid separator 2200 is arranged in the first accommodating chamber 2120 and is connected to the first tank body 2100, and the outlet of the purge pipeline 1000 is toward the gas-liquid separator 2200; the filter device 3000 is connected to the first exhaust port 2130; the input pipeline 4000 is connected to the first accommodating chamber 2120; the output pipeline 5000 is connected to the methanol daily tank, and the first accommodating chamber 2120 and the filter device 3000 are respectively connected to the output pipeline 5000.

[0048] In some embodiments, the outlet of the purge line 1000 faces the gas-liquid separator 2200 so that the gas ejected from the purge line 1000 can be ejected toward the gas-liquid separator 2200 .

[0049] Specifically, part of the gaseous methanol that enters the collecting device 2000 through the purge pipe 1000 will condense and liquefy into liquid methanol after contacting the gas-liquid separator 2200. In some embodiments, the gas-liquid separator 2200 is made of stainless steel.

[0050] In some embodiments, the remaining gas that enters the collection device 2000 through the purge line 1000 and is not liquefied can enter the filter device 3000 through the first exhaust port 2130. The filter device 3000 can adsorb and filter the incoming methanol gas and liquid to intercept the methanol and discharge the remaining gas.

[0051] In some embodiments, the input line 4000 is used to inject gas into the collection device 2000 to adjust the pressure within the collection device 2000. In some embodiments, the gas injected into the collection device 2000 by the delivery line is an inert gas. In some embodiments, the inert gas is nitrogen, and the end of the input line 4000 remote from the collection device 2000 is connected to a nitrogen source. In some embodiments, the nitrogen source can be a nitrogen generator or a nitrogen tank.

[0052] In some embodiments, the output pipeline 5000 is used to guide the liquid methanol collected in the collection device 2000 and the filtering device 3000 to the methanol daily use tank to achieve the recovery of residual methanol.

[0053] In the above embodiment, the collection device 2000 can collect gaseous and liquid methanol from the purge line 1000, achieving a primary collection of the portion of methanol remaining in the methanol supply line. This primary collection of methanol is then delivered to the methanol daily storage tank via the output line 5000 connected to the collection device 2000, thereby reducing methanol loss. Simultaneously, the filtering device 3000 can perform a secondary filtration of the gas and liquid from the collection device 2000, intercepting the majority of the gaseous methanol from the collection device 2000, achieving a secondary collection of methanol. This secondary collection of methanol is then delivered to the methanol daily storage tank via the output line 5000 connected to the filtering device 3000, further reducing methanol loss. Furthermore, the gas-liquid separator 2200 disposed within the collection device 2000 can liquefy a portion of the gaseous methanol that enters the collection device 2000, thereby passing through the collection device 2000 and into the output line 5000. This improves the methanol collection efficiency of the collection device 2000 and further reduces methanol loss.

[0054] In some embodiments, see Figure 2 and Figure 3 The first tank body 2100 has an inner wall 2140, which surrounds a first accommodating cavity 2120. The collecting device 2000 also includes a support member 2300, which is arranged in the first accommodating cavity 2120 and connected to the inner wall 2140. The gas-liquid separator 2200 is connected to the support member 2300.

[0055] In some embodiments, the support member 2300 is welded to the first tank body 2100 .

[0056] In some embodiments, the gas-liquid separator 2200 is connected to one side of the support 2300 along the first direction X, and the purge line 1000 is connected to the first tank body 2100 from the other side of the support 2300. The first direction X is the direction of the arrow X in the accompanying drawings.

[0057] In some embodiments, the first tank body 2100 has an inspection hole, and the gas-liquid separator 2200 is detachably connected to the support member 2300 so that an operator can replace or maintain the gas-liquid separator through the inspection hole.

[0058] In some embodiments, the gas-liquid separator 2200 is connected to the support member 2300 by bolts to achieve a detachable connection.

[0059] In the above embodiment, the support member 2300 is provided so that the gas-liquid separator 2200 can be as close to the purge pipeline 1000 as possible, thereby improving the efficiency of the gas-liquid separator 2200 in liquefying gaseous methanol from the purge pipeline 1000, thereby improving the methanol collection efficiency of the collection device 2000.

[0060] In some embodiments, please refer again to Figure 2 and Figure 3 The gas-liquid separator 2200 has a second accommodating chamber 2210 connected to the first accommodating chamber 2120, and the second accommodating chamber 2210 has an opening 2220. The gas-liquid separator 2200 also has a first through hole 2230 connected to the second accommodating chamber 2210 and the first accommodating chamber 2120. The purge pipeline 1000 is arranged in the opening 2220, and the outlet of the purge pipeline 1000 is connected to the second accommodating chamber 2210.

[0061] Specifically, the gas-liquid separator 2200 having the second accommodating chamber 2210 is covered at one end of the purge pipeline 1000 close to the outlet, that is, the portion of the purge pipeline 1000 close to the outlet is arranged in the second accommodating chamber 2210 .

[0062] In some embodiments, the gas-liquid separator 2200 includes a bottom plate and a side plate, wherein the side plate is connected to one side of the bottom plate along the first direction X, and the bottom plate and the side plate enclose a first accommodating cavity 2120. The gas-liquid separator 2200 has a plurality of first through holes 2230, wherein a portion of the plurality of first through holes 2230 is disposed in the bottom plate, and a portion of the plurality of first through holes 2230 is disposed in the side plate.

[0063] In the above embodiment, by providing the second accommodating cavity 2210 within the gas-liquid separator 2200 to increase the surface area of ​​the gas-liquid separator 2200, the likelihood of gaseous methanol entering the collection device 2000 through the purge line 1000 coming into contact with the gas-liquid separator 2200 is increased, thereby improving the methanol collection efficiency of the collection device 2000. Furthermore, by arranging the portion of the purge line 1000 near the outlet within the second accommodating cavity 2210, the likelihood of gas flowing out of the purge line 1000 coming into contact with the gas-liquid separator 2200 is increased, thereby increasing the likelihood of liquefaction of the gaseous methanol flowing out of the purge line 1000, thereby improving the methanol collection efficiency of the collection device 2000.

[0064] In some embodiments, please refer again to Figure 2 and Figure 3 The gas-liquid separator 2200 includes a main body 2240 and a cover plate 2250. The main body 2240 has a second accommodating cavity 2210 and an opening 2220. The first through hole 2230 is at least arranged on the main body 2240; the cover plate 2250 covers the opening 2220. The cover plate 2250 has a second through hole 2251. The purge pipeline 1000 is passed through the second through hole 2251. The cover plate 2250 is connected to the support member 2300.

[0065] In the above embodiment, the cover plate 2250 is provided to further increase the surface area of ​​the gas-liquid separator 2200, thereby increasing the likelihood that gaseous methanol entering the collection device 2000 via the purge line 1000 will come into contact with the gas-liquid separator 2200, thereby improving the methanol collection efficiency of the collection device 2000. Furthermore, the first through hole 2230 provided in the body 2240 allows the liquefied methanol to flow through the first through hole 2230 as quickly as possible to the first accommodating chamber 2120, where it can be quickly transported to the methanol daily storage tank via the output line 5000. This shortens the methanol recovery time and improves the methanol recovery efficiency. Furthermore, unliquefied gas can also quickly flow out of the gas-liquid separator 2200 via the first through hole 2230 to enter the filtration device 3000, shortening the methanol collection time.

[0066] In some embodiments, the cover plate 2250 is connected to the body 2240 by welding.

[0067] In some embodiments, the cover plate 2250 has a first connection hole spaced apart from the second through hole 2251, and the support member 2300 has a second connection hole. The first connection hole passes through the cover plate 2250 along the first direction X, and the second connection hole passes through the support member 2300 along the first direction X. The gas-liquid separator 2200 and the support member 2300 are connected by a threaded connection pair that is simultaneously provided through the first connection hole and the second connection hole.

[0068] In some embodiments, please refer again to Figure 3 The cover plate 2250 has a third through hole 2252 , which is connected to the first accommodating cavity 2120 and the second accommodating cavity 2210 , and the third through hole 2252 is spaced apart from the second through hole 2251 .

[0069] Specifically, the third through hole 2252 passes through the cover plate 2250 along the first direction X.

[0070] In some embodiments, the cover plate 2250 has a plurality of third through holes 2252 , and the plurality of third through holes 2252 are arranged around the second through holes 2251 .

[0071] In the above embodiment, the third through hole 2252 enables the unliquefied gas to enter the first accommodating chamber 2120 from the second accommodating chamber 2210 as quickly as possible, so that the unliquefied gas can enter the filtering device 3000 as quickly as possible for the second collection of methanol, thereby shortening the time for collecting methanol.

[0072] In some embodiments, see Figure 1 、 Figure 2 and Figure 5The collection device 2000 is connected to multiple purge pipelines 1000, and the multiple purge pipelines 1000 include a first purge pipeline 1100 and a second purge pipeline 1200; the methanol collection equipment includes multiple gas-liquid separators 2200, and the multiple gas-liquid separators 2200 include a first gas-liquid separator 2260 and a second gas-liquid separator 2270.

[0075] In the above embodiment, the first gas-liquid separator 2260 covered at the outlet of the first purge pipeline 1100 can reduce the possibility of the methanol ejected from the first purge pipeline 1100 entering the second purge pipeline 1200, and can also reduce the possibility of the methanol ejected from the second purge pipeline 1200 entering the first purge pipeline 1100; similarly, the second gas-liquid separator 2270 covered at the outlet of the second purge pipeline 1200 can reduce the possibility of the methanol ejected from the second purge pipeline 1200 entering the first purge pipeline 1100, and can also reduce the possibility of the methanol ejected from the first purge pipeline 1100 entering the second purge pipeline 1200.

[0076] In other embodiments, there are multiple purge pipelines 1000 and multiple gas-liquid separators 2200 , and the second accommodating cavity 2210 of each gas-liquid separator 2200 is connected to the outlet of at most one purge pipeline 1000 .

[0080] In the above embodiment, a pumping device 7000 is provided to provide power to the methanol in the output pipeline 5000, allowing the methanol in the output pipeline 5000 to enter the methanol daily storage tank, thereby recovering the methanol and reducing the methanol loss rate. Furthermore, a pressure regulating valve 6000 is provided in the input pipeline 4000 to limit the pressure within the collection device 2000, thereby maintaining the pumping device 7000 in a suitable operating condition to complete the methanol pumping operation.

[0081] In some embodiments, the pumping device 7000 includes a first branch 7100, a first pump 7200, a first stop valve 7300, a second branch 7400, a second pump 7500 and a second stop valve 7600, the first branch 7100 is connected to the output pipeline 5000; the first pump 7200 is connected to the output pipeline 5000, and the first pump 7200 is connected to the methanol daily tank; the first stop valve 7300 is arranged between the first branch 7100 and the output pipeline 5000, and is used to open or close the first branch 7100; the second branch 7400 is connected to the output pipeline 5000; the second pump 7500 is connected to the output pipeline 5000, and the second pump 7500 is connected to the methanol daily tank; the second stop valve 7600 is arranged between the second branch 7400 and the output pipeline 5000, and is used to open or close the second branch 7400.

[0087] In the above embodiment, a bypass line 8000 is provided to bypass the pressure regulating valve 6000 to avoid the nitrogen entering the first accommodating chamber 2120 from being affected by the pressure regulating valve 6000 when the first accommodating chamber 2120 is replaced with nitrogen, thereby shortening the time for nitrogen replacement of the first accommodating chamber 2120 and improving the efficiency of nitrogen replacement of the first accommodating chamber 2120, thereby improving the working efficiency of the collection device 2000.

[0088] In some embodiments, see Figure 4 The filtering device 3000 includes a second tank body 3100 and a filter element 3200. The second tank body 3100 has a third accommodating chamber 3110 and a second exhaust port 3120 connected to the third accommodating chamber 3110. The filter element 3200 is arranged in the third accommodating chamber 3110. The filter element 3200 is connected to the second tank body 3100. The filter element 3200 divides the third accommodating chamber 3110 into a first sub-chamber 3111 and a second sub-chamber 3112. The first sub-chamber 3111 is connected to the first exhaust port 2130. The first sub-chamber 3111 is connected to the output pipeline 5000, and the second sub-chamber 3112 is connected to the second exhaust port 3120.

[0089] In some embodiments, filter element 3200 includes glass fibers and carbon fibers.

[0090] In the above embodiment, other gases entering along with the methanol vapor can flow from the first sub-chamber 3111 through the filter element 3200 to the second sub-chamber 3112, and then be exhausted from the second exhaust port 3120. Simultaneously, the methanol vapor from the collection device 2000 is intercepted and adsorbed by the filter element 3200, where it converges into a liquid state and flows to the output pipeline 5000, thus achieving a second collection of the methanol.

[0091] In some embodiments, please refer again to Figure 4 The filter device 3000 also includes a guide cover 3300, which is arranged in the first sub-cavity 3111 and connected to the second tank body 3100. The guide cover 3300 has a guide cavity 3330, and the guide cavity 3330 forms an air inlet 3310 and an air outlet 3320 in the guide cover 3300. The first exhaust port 2130 faces the air inlet 3310, and the air outlet 3320 faces the filter element 3200. Along the direction from the air inlet 3310 to the air outlet 3320, the size of the guide cavity 3330 increases perpendicular to the direction from the air inlet 3310 to the air outlet 3320.

[0092] Specifically, the flow cross-sectional area at the air inlet 3310 is smaller than the flow cross-sectional area at the air outlet 3320 .

[0093] In some embodiments, the direction from the air inlet 3310 to the air outlet 3320 is a first direction X, and the guide cover 3300 includes a first portion and a second portion. The first portion is conical, with the air outlet 3320 disposed in the first portion, connected to the second tank 3100, and facing the filter element 3200. The second portion is connected to a side of the first portion away from the filter element 3200 along the first direction, and the air inlet 3310 is disposed at an end of the second portion away from the first portion.

[0094] In some embodiments, the first portion and the second portion are a unitary structure.

[0095] In some embodiments, a portion of the filter element 3200 is located within the guide cavity 3330 .

[0096] In the above embodiment, the gas entering the first sub-chamber 3111 from the first exhaust port 2130 has a reduced flow rate after passing through the guide cover 3300, which can reduce the impact of the gas impacting the filter element 3200 on the filter element 3200, thereby extending the life of the filter element 3200 and reducing the maintenance frequency of the filter element 3200.

[0097] In some embodiments, the methanol collection device further includes a liquid collecting tray 9000, the collecting device 2000, the filtering device 3000 and the output pipeline 5000 are arranged on one side of the liquid collecting tray 9000 along the first direction X, the liquid collecting tray 9000 has a liquid collecting chamber 9100 and a liquid collecting port 9200 that are interconnected, and the liquid collecting chamber 9100 is arranged along the first direction X toward the collecting device 2000, the filtering device 3000 and the output pipeline 5000; the collecting device 2000 includes a first discharge valve connected to the first tank body 2100, the filtering device 3000 includes a second discharge valve connected to the second tank body 3100, and the output pipeline 5000 is provided with a third discharge valve, and the liquid outlets of the first discharge valve, the second discharge valve and the third discharge valve are facing the liquid collecting chamber 9100.

[0098] In the above embodiment, by providing the first relief valve, the second relief valve and the third relief valve, the methanol in the collection device 2000, the filtering device 3000 and the output pipeline 5000 can be discharged as much as possible before the methanol collection device is shut down for a long time.

[0099] In some embodiments, the liquid collecting tray 9000 has a bottom wall for enclosing a liquid collecting chamber 9100, and the bottom wall is inclined in a direction perpendicular to the first direction X so as to guide the liquid in the liquid collecting chamber 9100 to the liquid collecting port 9200, thereby facilitating the collection of the liquid in the liquid collecting chamber 9100.
