Description

Technical Field

[0001] This invention relates to the field of marine technology, specifically to a marine methanol fuel supply and storage tank assembly. Background Technology

[0002] As the shipping industry transforms towards low-carbon and environmentally friendly practices, green methanol, as a clean and environmentally friendly carbon-neutral fuel, has become an important development direction for marine fuels due to its significant advantages, including reducing sulfur oxides (SOx) emissions by approximately 99%, nitrogen oxides by 80%, and carbon dioxide emissions by up to 25%. It is widely used in the fuel supply and storage systems of various types of ships. Marine methanol fuel supply and storage tanks, as the core equipment for methanol fuel storage and transportation, directly determine the navigation safety and environmental compliance of ships based on their operational stability and safety. Pressure detection, methanol volatile gas condensation and recovery, methanol-water separation, and media reuse and discharge are key technical aspects that ensure the efficient, safe, and environmentally friendly operation of the tanks, and are also core pain points that urgently need optimization and improvement in the industry.

[0003] In terms of pressure detection and control, traditional marine methanol storage tanks mostly use single-point pressure sensors to detect the pressure inside the tank, which can only realize overpressure alarm or passive pressure relief. They cannot adapt to the dynamic changes in tank pressure caused by the volatility of methanol. Methanol is highly volatile at room temperature. Temperature fluctuations and changes in tank liquid level during ship navigation will cause frequent small fluctuations in pressure. Single-point detection is prone to data lag and detection blind spots. Moreover, the pressure relief process directly releases methanol vapors into the atmosphere, which not only wastes fuel but also releases toxic and harmful gases, which does not meet the environmental emission requirements of ships.

[0004] The liquid formed after the condensation of recovered methanol vapor is a mixture of methanol and infiltrated water. Commonly used electric centrifugal or membrane filter oil-water separators on ships have limited efficiency in separating trace amounts of water and suffer from problems such as easy clogging, frequent maintenance, and dependence on electricity. Under the long-term tilting and vibration conditions of ships, their separation stability decreases. A passive separation structure based entirely on physical principles such as gravity, capillary action, or centrifugal force is needed, requiring no precision filter element and adaptable to the dynamic environment of ships.

[0005] Returning the separated pure methanol to the storage tank and safely draining the separated water currently requires two independent pumping systems and complex electrical control logic for liquid level and purity. This not only increases system complexity but also creates new potential points of failure. A misjudgment in the control logic could lead to water being accidentally injected into the fuel tank or methanol being accidentally discharged into the sea, causing a serious accident. Summary of the Invention

[0006] The technical problem to be solved by the present invention is the problem of pressure detection and methanol volatile gas recovery and separation of marine methanol fuel supply and storage tank group, and provides a marine methanol fuel supply and storage tank group.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The methanol fuel supply and storage compartment includes a feed port and a replenishment port on the compartment body, and a controller is installed on the compartment body; The cabin is equipped with a detection unit, which includes a detection component. The detection component controls the start and stop of the recovery unit and the separation unit through changes in cabin pressure. The detection unit includes a detection element and a control element. The detection element is fixedly installed inside the cabin, and the control element is fixedly installed inside the cabin. The detection unit is equipped with a recycling unit; The recovery unit includes a separation unit comprising a separation component that separates methanol from water through positional changes. The separation component includes a separation element and a discharge element, which are slidably connected. The discharge element is also slidably connected to the recovery unit. The controller is electrically connected to both the control element and the discharge element, receiving signals and controlling the coordinated operation of these components. Existing technologies lack timely processing structures for pressure detection and recovery separation of volatile methanol gases within methanol storage tanks. This can easily lead to excessive pressure and methanol leakage, affecting the stability and safety of methanol fuel storage and transportation. Furthermore, it results in significant waste of volatile methanol gases and the inability to recycle and reuse them. This invention addresses the problems of untimely pressure control, methanol waste, and significant safety hazards in existing technologies by setting up a detection unit, a recovery unit, and a separation unit that work collaboratively. This allows for real-time pressure monitoring of the storage tank while simultaneously recovering and separating volatile methanol gases, ensuring stable tank pressure and improving methanol utilization.

[0008] Furthermore, the detection component includes a straight cylinder, a retaining ring, a return spring, a sliding plate, a straight rod, and a push plate. The straight cylinder is fixedly installed at the feed inlet on the tank body. A retaining ring is provided inside the straight cylinder, and the retaining ring is fixedly connected to the sliding plate via the return spring. The straight rod is fixedly connected to the sliding plate. The push plate is slidably installed inside the straight cylinder, and the push plate is fixedly connected to the straight rod. Existing technologies often use single-point sensors for methanol storage tank pressure detection, which suffers from detection lag, blind spots, and the inability to directly link with the recovery and separation systems, resulting in untimely responses. This invention, through the detection component, utilizes tank pressure changes to directly drive the push plate and straight rod in linkage, eliminating the need for complex electronic control sensors, providing a fast response speed, and directly triggering subsequent component actions. This solves the problems of existing pressure detection lag, poor linkage, and insufficient reliability.

[0009] Furthermore, the control component includes a conductive block, a conductive plate, a drive coil, and a conductive ring. The conductive block is fixedly mounted on the push plate, the conductive plate is mounted inside the straight cylinder via a spring, the drive coil is fixedly mounted on the straight rod, and the conductive ring is slidably connected to the straight rod and fixedly mounted inside the straight cylinder. Existing technologies suffer from complex control linkage structures for pressure detection and recovery / separation units, numerous electronic components, high failure rates, and an inability to achieve precise start-stop control based on chamber pressure changes, leading to malfunctions or delayed actions. This invention, through the control component and the mechanical sliding of the detection component, achieves precise linkage control of the recovery and separation units, resulting in a simple structure and low failure rate.

[0010] Furthermore, the end of the drive coil near the retaining ring is the current input terminal.

[0011] Furthermore, the separating element includes a wedge-shaped separating block, a flow channel, and a separating tube. The wedge-shaped separating block has a hollow design, and flow channels are provided on both sides of the wedge-shaped separating block. A one-way valve is provided on the flow channel, and the surface of the flow channel is treated with a hydrophilic coating. The separating tube is fixedly connected to the wedge-shaped separating block. Existing technologies suffer from low separation efficiency and insufficient separation precision in methanol-water separation structures, failing to quickly achieve stratification of methanol and water, and prone to secondary mixing of separated methanol and water. Additionally, they suffer from poor flow guidance and are prone to liquid accumulation. This invention, through a separating element, utilizes a wedge-shaped structure to accelerate stratification, a hydrophilic flow channel to guide water flow, a one-way valve to prevent secondary mixing, and a hollow design combined with a separating tube to achieve precise delivery of the separated medium, thus solving the problems of low efficiency, insufficient precision, and easy secondary mixing in existing separation structures.

[0012] Furthermore, the discharge component includes an extraction box and a partition. The straight rod is slidably connected to the extraction box, and a telescopic sealing baffle adapted to the straight rod is provided at the contact end between the straight rod and the extraction box. The separation pipe is slidably connected to the extraction box, and a telescopic sealing baffle adapted to the separation pipe is provided at the contact end between the separation pipe and the extraction box. The extraction box is slidably connected to the partition, and the partition is slidably connected to the straight rod. A stop is provided at the contact end between the partition and the straight rod to ensure that the straight rod and the partition can slide relative to each other while moving synchronously. Existing technologies have the problem of not being able to achieve precise discharge and transportation of methanol and water after separation. This invention optimizes the sliding connection structure by setting an extraction box, a partition, and a telescopic sealing baffle, using a stop to ensure the coordinated movement of the straight rod and the partition, and improving the sealing performance through the telescopic sealing baffle, thereby achieving precise discharge and transportation of the separated medium.

[0013] Furthermore, the extraction chamber is divided into two chambers, a left chamber and a right chamber, by a partition. The left chamber is filled with air, while the right chamber is a vacuum. Two solenoid valves are installed in the right chamber, located inside the separation tube and at the bottom of the right chamber, respectively. Existing technologies suffer from the problem of failing to create an effective negative pressure for media extraction, leading to decreased separation efficiency. This invention addresses this by dividing the extraction chamber into left and right chambers, and using the two solenoid valves in the right chamber to control the entry of media into the separation tube and the discharge of media from the bottom of the right chamber, achieving precise extraction and diversion of the media and avoiding residue and turbulence.

[0014] Furthermore, the recycling unit includes a recycling box, an air pump, and an electric push rod. The wedge-shaped separation block is slidably connected to the recycling box, and the extraction box is slidably connected to the recycling box. An air pump is installed on the recycling box. The fixed end of the electric push rod is fixedly installed inside the recycling box, and the telescopic end of the electric push rod is fixedly connected to the wedge-shaped separation block. A solenoid valve is installed at the bottom of the recycling box, and a condenser is installed on the inner wall of the recycling box.

[0015] Furthermore, the conductive ring is electrically connected to the electric push rod, and the conductive plate is electrically connected to the suction pump.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention addresses the issue of methanol in the tank gradually increasing in volatile gases due to temperature fluctuations and liquid level changes during ship navigation. This leads to a gradual increase in tank pressure. Under this pressure, a sliding plate slides to the right along a straight cylinder, simultaneously stretching a return spring. This, in turn, drives a push plate to move synchronously to the right under the transmission of a straight rod. As the push plate moves, the conductive block on the push plate gradually approaches and contacts the conductive plate inside the straight cylinder. At this point, the controller's current is transmitted to the suction pump through the conductive block and the conductive plate, thus controlling the suction pump to start. Simultaneously, as the drive coil on the straight rod gradually contacts the conductive ring, the effective number of turns in the circuit gradually decreases. This causes the current transmitted by the controller to the electric push rod through the drive coil and the conductive ring to gradually increase, thereby controlling the extension distance of the electric push rod to gradually increase.

[0017] 2. In this invention, when the baffle is pushed to the right by the straight rod, the controller closes the two solenoid valves. As the condensed mixed droplets collect at the separation station below the wedge-shaped separator, when the wedge-shaped separator is driven downward by the electric push rod, its inclined surface begins to squeeze the mixed liquid below. Under the action of gravity, the liquid flows towards the wedge-shaped separator. During the flow along the inclined surface, the density difference plays a role. The heavier water tends to sink and flow close to the surface of the inclined surface, while the lighter methanol is located at the top of the liquid layer, forming an instantaneous vertical stratification. The drainage channels on both sides of the wedge-shaped separator are hydrophilic. Water quickly adheres to the inner wall of the drainage channels under the action of gravity and capillary action, while methanol, due to its hydrophobicity, cannot enter the drainage channels and can only collect in the outer cavity of the wedge-shaped separator, forming a cavity with methanol on the outside and water in the middle. In the stratified state, after separation, the controller controls the solenoid valve at the bottom of the recovery tank to open, allowing methanol to be reintroduced into the chamber. The one-way valve prevents water from flowing back into the hollow cavity, avoiding secondary mixing of methanol and water, thus achieving initial and efficient stratification. When a large amount of volatile gas is extracted from the chamber and the chamber pressure drops to the normal range, the push plate loses the thrust of the high-pressure gas. During the process of the return spring driving the slide plate, straight rod, and push plate to move to the left, the straight rod pulls the partition to the left. At this time, the controller controls the solenoid valve in the separation tube to open first. Since the right chamber is in a vacuum state, the water stored in the hollow cavity of the wedge-shaped separation block is transported to the right chamber for storage through the separation tube under the action of atmospheric pressure difference. When the pressure in the chamber is stable, the controller controls the solenoid valve at the bottom of the right chamber to open, completing the water transfer.

[0018] 3. In this invention, when the conductive block contacts the conductive plate, the external air pressure still provides a pushing force to the push plate. Under the buffering effect of the spring, the conductive plate and the conductive block continue to be in contact for a period of time, providing sufficient buffer time for the suction pump to draw in the gas and for the condenser to condense the volatile gas, forming condensate droplets. The suction pump starts immediately and uses negative pressure to draw the methanol volatile gas in the chamber into the recovery tank. After the volatile gas enters the recovery tank, the condenser on the inner wall of the recovery tank starts and condenses the gaseous methanol into a liquid state. The condensed liquid medium is a mixture of methanol and water, which flows to the separation station of the recovery tank under the action of gravity. At the same time, the electric push rod is energized and its telescopic end pushes the wedge-shaped separation block to slide in the recovery tank to the designated separation station to perform the separation action of methanol and water.

[0021] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Figures 1-9 As shown, the present invention provides the following technical solution: like Figures 1-4 As shown, the methanol fuel supply and storage compartment includes a compartment 1 with a feed port and a replenishment port, and a controller is installed on the compartment 1. A detection unit 2 is provided on the cabin 1. The detection unit 2 includes a detection component. The detection component controls the start and stop of the recovery unit 3 and the separation unit 4 through the change of cabin pressure. The detection unit 2 includes a detection component and a control component. The detection component is fixedly installed in the cabin 1, and the control component is fixedly installed in the cabin 1. The detection unit 2 is equipped with a recycling unit 3; The recovery unit 3 is equipped with a separation unit 4, which includes a separation component. The separation component separates methanol and water by changing its position. The separation component includes a separation element and a discharge element. The separation element and the discharge element are slidably connected. The discharge element is slidably connected to the recovery unit 3. The controller is electrically connected to the control element and the discharge element respectively, and is used to receive signals and control the coordinated action of the components.

[0023] like Figures 4-7As shown, the detection components include a straight cylinder 21, a retaining ring 22, a return spring 23, a sliding plate 24, a straight rod 25, and a push plate 26. The straight cylinder 21 is fixedly installed at the feeding port on the chamber 1. A retaining ring 22 is provided inside the straight cylinder 21. The retaining ring 22 is fixedly connected to the sliding plate 24 through the return spring 23. The straight rod 25 is fixedly connected to the sliding plate 24. The push plate 26 is slidably installed inside the straight cylinder 21. The push plate 26 is fixedly connected to the straight rod 25.

[0024] like Figure 5 , Figure 7 As shown, the control components include a conductive block 27, a conductive plate 28, a drive coil 29, and a conductive ring 210. The conductive block 27 is fixedly mounted on the push plate 26. The conductive plate 28 is mounted inside the straight cylinder 21 by a spring. The drive coil 29 is fixedly mounted on the straight rod 25. The conductive ring 210 is slidably connected to the straight rod 25 and is fixedly mounted inside the straight cylinder 21.

[0025] like Figure 4 , Figure 5 As shown, the end of the drive coil 29 closest to the retaining ring 22 is the current input terminal.

[0026] When the methanol in the tank 1 gradually produces more volatile gases due to temperature fluctuations and liquid level changes during ship navigation, the pressure inside the tank gradually increases. Under the action of pressure, the sliding plate 24 is driven to slide to the right along the straight cylinder 21, while the return spring 23 is stretched. Under the transmission action of the straight rod 25, the push plate 26 moves to the right synchronously. As the push plate 26 moves, the conductive block 27 on the push plate 26 gradually approaches and contacts the conductive plate 28 inside the straight cylinder 21. At this time, the current of the controller is transmitted to the suction pump 32 through the conductive block 27 and the conductive plate 28, thereby controlling the suction pump 32 to start. At the same time, as the drive coil 29 on the straight rod 25 gradually contacts the conductive ring 210, the effective number of turns connected to the circuit gradually decreases, thereby causing the current transmitted by the controller to the electric push rod 33 through the drive coil 29 and the conductive ring 210 to gradually increase, thereby controlling the extension distance of the electric push rod 33 to gradually increase.

[0027] like Figure 8 , Figure 9 As shown, the separation component includes a wedge-shaped separation block 41, a diversion groove 42, and a separation tube 43. The wedge-shaped separation block 41 is hollow, and diversion grooves 42 are provided on both sides of the wedge-shaped separation block 41. A one-way valve is provided on the diversion groove 42, and the surface of the diversion groove 42 is hydrophilic. The separation tube 43 is fixedly connected to the wedge-shaped separation block 41.

[0028] like Figure 7As shown, the discharge component includes an extraction box 44 and a partition plate 45. A straight rod 25 is slidably connected to the extraction box 44. A telescopic sealing baffle adapted to the straight rod 25 is provided at the contact end between the straight rod 25 and the extraction box 44. A separation pipe 43 is slidably connected to the extraction box 44. A telescopic sealing baffle adapted to the separation pipe 43 is provided at the contact end between the separation pipe 43 and the extraction box 44. The extraction box 44 is slidably connected to the partition plate 45. The partition plate 45 is slidably connected to the straight rod 25. A stop is provided at the contact end between the partition plate 45 and the straight rod 25 to ensure that the straight rod 25 and the partition plate 45 can slide relative to each other while moving synchronously.

[0029] like Figure 7 As shown, the extraction box 44 is divided into two chambers, a left chamber and a right chamber, by a partition 45. The left chamber is filled with air, while the right chamber is a vacuum. Two solenoid valves are installed in the right chamber, located in the separation tube 43 and at the bottom of the right chamber, respectively.

[0030] When the straight rod 25 pushes the partition 45 to the right, the controller closes the two solenoid valves. As the condensed mixed droplets gather at the separation station below the wedge-shaped separator 41, when the wedge-shaped separator 41 is driven downward by the electric push rod 33, its inclined surface begins to squeeze the mixed liquid below. Under the action of gravity, the liquid flows towards the wedge-shaped separator 41. During the flow along the inclined surface, the density difference plays a role. The heavier water tends to sink and flow close to the surface of the inclined surface, while the lighter methanol is located at the top of the liquid layer, forming an instantaneous vertical stratification. The drainage grooves 42 on both sides of the wedge-shaped separator 41 are hydrophilic. Water quickly adheres to the inner wall of the drainage grooves 42 under the action of gravity and capillary action, while methanol, due to its hydrophobicity, cannot enter the drainage grooves 42 and can only gather in the outer cavity of the wedge-shaped separator 41, forming a stratified state with methanol on the outside and water in the hollow cavity. After separation, the controller controls the solenoid valve at the bottom of the recovery tank 31 to open, allowing methanol to be reintroduced into the chamber 1. The one-way valve prevents water from flowing back into the hollow cavity, avoiding secondary mixing of methanol and water, and achieving initial efficient stratification. When a large amount of volatile gas is extracted from the chamber 1 and the chamber pressure drops to the normal range, the push plate 26 loses the thrust of the high-pressure gas. During the process of the return spring 23 driving the slide plate 24, the straight rod 25 and the push plate 26 to move to the left, the straight rod 25 pulls the partition 45 to move to the left. At this time, the controller controls the solenoid valve in the separation tube 43 to open first. Since the right chamber is in a vacuum state, the water stored in the hollow cavity of the wedge-shaped separation block 41 is transported to the right chamber for storage through the separation tube 43 under the action of atmospheric pressure difference. When the pressure inside the chamber is stable, the controller controls the solenoid valve at the bottom of the right chamber to open, completing the water transport.

[0031] like Figure 6 As shown, Figures 1-4As shown, the recycling unit 3 includes a recycling box 31, an air pump 32, and an electric push rod 33. The wedge-shaped separation block 41 is slidably connected to the recycling box 31, and the extraction box 44 is slidably connected to the recycling box 31. The air pump 32 is installed on the recycling box 31. The fixed end of the electric push rod 33 is fixedly installed inside the recycling box 31, and the telescopic end of the electric push rod 33 is fixedly connected to the wedge-shaped separation block 41. A solenoid valve is installed at the bottom of the recycling box 31, and a condenser is installed on the inner wall of the recycling box 31.

[0032] like Figure 5 , Figure 6 As shown, the conductive ring 210 is electrically connected to the electric push rod 33, and the conductive plate 28 is electrically connected to the suction pump 32.

[0033] When the conductive block 27 contacts the conductive plate 28, the external air pressure still provides a pushing force to the push plate 26. Under the buffering effect of the spring, the conductive plate 28 and the conductive block 27 continue to contact each other for a period of time, providing sufficient buffer time for the suction pump 32 to draw in the gas and for the condenser to condense the volatile gas, forming condensate droplets. The suction pump 32 starts immediately and draws the methanol volatile gas in the chamber 1 into the recovery box 31 through negative pressure suction. After the volatile gas enters the recovery box 31, the condenser on the inner wall of the recovery box 31 starts and condenses the gaseous methanol into liquid. The condensed liquid medium is a mixture of methanol and water, which flows to the separation station of the recovery box 31 under the action of gravity. At the same time, the electric push rod 33 is energized and its telescopic end pushes the wedge-shaped separation block 41 to slide in the recovery box 31 to the designated separation station to perform the separation action of methanol and water.

[0034] Working principle of the invention: When the methanol in the tank 1 gradually produces more volatile gases due to temperature fluctuations and liquid level changes during ship navigation, the pressure inside the tank gradually increases. Under the action of pressure, the sliding plate 24 is driven to slide to the right along the straight cylinder 21, while the return spring 23 is stretched. Under the transmission action of the straight rod 25, the push plate 26 moves to the right synchronously. As the push plate 26 moves, the conductive block 27 on the push plate 26 gradually approaches and contacts the conductive plate 28 inside the straight cylinder 21. At this time, the current of the controller is transmitted to the suction pump 32 through the conductive block 27 and the conductive plate 28, thereby controlling the suction pump 32 to start. At the same time, as the drive coil 29 on the straight rod 25 gradually contacts the conductive ring 210, the effective number of turns connected to the circuit gradually decreases, thereby causing the current transmitted by the controller to the electric push rod 33 through the drive coil 29 and the conductive ring 210 to gradually increase, thereby controlling the extension distance of the electric push rod 33 to gradually increase.

[0035] When the straight rod 25 pushes the partition 45 to the right, the controller closes the two solenoid valves. As the condensed mixed droplets gather at the separation station below the wedge-shaped separator 41, when the wedge-shaped separator 41 is driven downward by the electric push rod 33, its inclined surface begins to squeeze the mixed liquid below. Under the action of gravity, the liquid flows towards the wedge-shaped separator 41. During the flow along the inclined surface, the density difference plays a role. The heavier water tends to sink and flow close to the surface of the inclined surface, while the lighter methanol is located at the top of the liquid layer, forming an instantaneous vertical stratification. The drainage grooves 42 on both sides of the wedge-shaped separator 41 are hydrophilic. Water quickly adheres to the inner wall of the drainage grooves 42 under the action of gravity and capillary action, while methanol, due to its hydrophobicity, cannot enter the drainage grooves 42 and can only gather in the outer cavity of the wedge-shaped separator 41, forming a stratified state with methanol on the outside and water in the hollow cavity. After separation, the controller controls the solenoid valve at the bottom of the recovery tank 31 to open, allowing methanol to be reintroduced into the chamber 1. The one-way valve prevents water from flowing back into the hollow cavity, avoiding secondary mixing of methanol and water, and achieving initial efficient stratification. When a large amount of volatile gas is extracted from the chamber 1 and the chamber pressure drops to the normal range, the push plate 26 loses the thrust of the high-pressure gas. During the process of the return spring 23 driving the slide plate 24, the straight rod 25 and the push plate 26 to move to the left, the straight rod 25 pulls the partition 45 to move to the left. At this time, the controller controls the solenoid valve in the separation tube 43 to open first. Since the right chamber is in a vacuum state, the water stored in the hollow cavity of the wedge-shaped separation block 41 is transported to the right chamber for storage through the separation tube 43 under the action of atmospheric pressure difference. When the pressure inside the chamber is stable, the controller controls the solenoid valve at the bottom of the right chamber to open, completing the water transport.

[0036] When the conductive block 27 contacts the conductive plate 28, the external air pressure still provides a pushing force to the push plate 26. Under the buffering effect of the spring, the conductive plate 28 and the conductive block 27 continue to contact each other for a period of time, providing sufficient buffer time for the suction pump 32 to draw in the gas and for the condenser to condense the volatile gas, forming condensate droplets. The suction pump 32 starts immediately and draws the methanol volatile gas in the chamber 1 into the recovery box 31 through negative pressure suction. After the volatile gas enters the recovery box 31, the condenser on the inner wall of the recovery box 31 starts and condenses the gaseous methanol into liquid. The condensed liquid medium is a mixture of methanol and water, which flows to the separation station of the recovery box 31 under the action of gravity. At the same time, the electric push rod 33 is energized and its telescopic end pushes the wedge-shaped separation block 41 to slide in the recovery box 31 to the designated separation station to perform the separation action of methanol and water.
