Abstract
Description
Technical Field

[0002] As the requirements for carbon emission reduction of ships become increasingly stringent, ammonia fuel, as a carbon-free fuel, is increasingly favored by shipowners. To ensure the safety of ammonia fuel use, its containment system and supply system need to be equipped with a venting release pipeline. Because ammonia fuel is a low-flashpoint fuel, the low-flashpoint fuel specification requires that the height of the venting mast be greater than 1 / 3 of the ship's width and at least 6 meters above the crew's working surface to accelerate the diffusion of combustible gases and avoid the formation of a flammable and explosive environment due to the accumulation of combustible gases.
[0003] The existing ventilation mast directly releases ammonia fuel into the atmosphere, which cannot effectively prevent the ammonia fuel from spreading from the ventilation mast to the living area, and there is a risk of crew poisoning caused by ammonia fuel. In addition, due to the layout of many existing ships, it is impossible to set the height of the ventilation mast to be greater than 1 / 3 of the ship's width, which makes the existing ships less safe and cannot meet the requirements.

[0034] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0035] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0037] In the description of the present invention, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0038] Figure 1 The structure diagram of the air-permeable mast device for a ship provided by the present invention is shown. Figure 1 As shown, the breathable mast device for ships includes a breathable header 1, a release pipe 2 and a recovery system 3, wherein the breathable header 1 includes a first tube 11 and a second tube 12 arranged at an angle, the first tube 11 is provided with a first interface 111, a second interface 112 and a third interface 113 in sequence, and the second tube 12 is connected to the outside; one end of the release pipe 2 is connected to the exhaust port of the ammonia fuel system, and the other end thereof is connected to the first interface 111, so that the ammonia fuel discharged from the ammonia fuel system can enter the first tube 11 of the breathable header 1; the recovery system 3 is used to collect the ammonia fuel entering into the breathable header 1 from the release pipe 2, thereby reducing the ammonia content in the gas discharged from the second tube 12 and reducing the risk of ammonia poisoning of the crew.
[0039] Figure 1 In the embodiment, the number of the release pipes 2 is two, and accordingly, the number of the first interfaces 111 on the first pipe 11 is also two, and the two release pipes 2 are connected to the first pipe 11 through one first interface 111 respectively. There may be multiple discharge ports of the ammonia fuel system, such as an ammonia fuel filling system, a containment system, a supply system, and an ammonia fuel device, so the number of the release pipes 2 can also be any number, which is not limited here.
[0040] The first tube 11 of the air-permeable manifold 1 extends in the horizontal direction. The first tube 11 is arranged to extend in the horizontal direction, which can slow down the flow rate of ammonia, thereby increasing the amount of ammonia dissolved in water and improving the ammonia recovery efficiency. Preferably, the first interface 111 is arranged at the top of the peripheral side wall of the first tube 11 to prevent the ammonia solution in the first tube 11 from flowing back into the release tube 2 through the first interface 111.
[0041] The marine ventilating mast device further comprises a first liquid level alarm 115, which is arranged in the first pipe 11, and the distance between the first liquid level alarm 115 and the bottom of the first pipe 11 is smaller than the distance between the first interface 111 and the bottom of the first pipe 11. When the first liquid level alarm 115 sounds an alarm, the circulation pump 32 can be stopped to reduce the amount of water sprayed into the first pipe 11, so as to prevent the ammonia solution in the first pipe 11 from flowing back into the release pipe 2 from the first interface 111.
[0042] Figure 1 In the embodiment, the second tube 12 is arranged vertically to the first tube 11. Since the temperature of the gas discharged from the ammonia fuel system is relatively high, even after being processed by the recovery system 3, the temperature of the gas is still relatively high. When the high-temperature gas enters the second tube 12, condensate is easily formed in the second tube 12. The second tube 12 is arranged in a vertical direction to facilitate the condensate to flow back to the first tube 11 smoothly.
[0043] Furthermore, the breathable mast device for ships also includes a breathable head 123, which is connected to the outlet end of the second pipe 12. The breathable head 123 can be used to prevent rainwater from entering the second pipe 12 and can release gases that cannot be absorbed by the recovery system 3, such as nitrogen.
[0044] The marine ventilating mast device further includes a demister 121, which is disposed on the second pipe 12. Since the recovery system 3 generates a small amount of ammonia solution mist while absorbing ammonia, the demister 121 can remove the ammonia solution mist and make it drip back into the first pipe 11 of the ventilating manifold 1, thereby preventing the ammonia solution mist from leaking out of the venting head 123 into the atmosphere, causing corrosion of the ship deck, and generating toxic ammonia. Of course, the demister 121 can also be installed outside the second pipe 12.
[0045] The ship's ventilated mast device also includes a first ammonia detector 122, which is arranged in the first tube 11 and above the demister 121. The first ammonia detector 122 is used to monitor the ammonia content in the exhaust gas after passing through the demister 121 to prevent the recovery system 3 from failing and causing ammonia to be released to the outside. The first ammonia detector 122 can be pre-set with a preset value that meets the requirements of national standards. When the ammonia content monitored by the first ammonia detector 122 exceeds the preset value, the first ammonia detector 122 issues an alarm, and the crew can switch the ship's power mode from the ammonia fuel mode to the fuel mode in time. Of course, in other embodiments, when the ammonia detector issues an alarm, the signal can also be transmitted to the ship's control system, and the control system controls the switching of the ship's power mode. Preferably, the first ammonia detector 122 is located above the connection between the vent pipe 36 and the second tube 12. Whether the recovery system 3 fails or ammonia is released in the collection circulation cabinet 31, the power mode of the ship needs to be switched to reduce the risk of ammonia poisoning of the crew and improve the safety of the ship.
[0046] Furthermore, a second ammonia detector 21 is provided on the release pipe 2, and the second ammonia detector 21 is used to detect whether ammonia is released. If so, the circulation pump 32 of the recovery system 3 is started to start the spray recovery mode.
[0047] Optionally, the first ammonia detector 122 and the second ammonia detector 21 installed on the release tube 2 may use the same type of ammonia monitoring device, or may use different types of ammonia monitoring devices, which is not limited here.
[0048] See also Figure 1 The recovery system 3 includes a collection circulation cabinet 31, a circulation pump 32, a spray pipe group 33 and a first recovery pipe 34. The collection circulation cabinet 31 is used to contain the solution. The outlet of the collection circulation cabinet 31 is connected to the inlet of the spray pipe group 33 through the circulation pump 32. The outlet of the spray pipe group 33 is connected to the second interface 112. The circulation pump 32 provides power for the spray pipe group 33, so that the liquid in the collection circulation cabinet 31 can be sprayed into the first pipe 11 of the air permeable manifold 1; one end of the first recovery pipe 34 is connected to the third interface 113, and the other end thereof is connected to the inlet of the collection circulation cabinet 31. Ammonia in the ammonia fuel system enters the first pipe 11 through the release pipe 2, and the recovery system 3 sprays water into the first pipe 11 through the spray pipe group 33. After the ammonia is dissolved in water, it enters the collection circulation cabinet 31 through the first recovery pipe 34, thereby completing the recovery of ammonia and reducing the ammonia content in the gas discharged from the second pipe 12. It is not necessary to set the height of the second pipe 12 to be greater than 1 / 3 of the ship width required by the specification, thereby reducing the risk of ammonia poisoning of the crew and improving the safety of the ship. The collection circulation cabinet 31 is arranged below the permeable manifold 1, so that the ammonia solution in the first pipe 11 of the permeable manifold 1 can enter the collection circulation cabinet 31 through the first recovery pipe 34 under the action of gravity.
[0049] The recovery system 3 also includes a second recovery pipe 35. The first pipe 11 is also provided with a fourth interface 114. One end of the second recovery pipe 35 is connected to the fourth interface 114, and the other end is connected to the inlet of the collection circulation cabinet 31. In this way, the ammonia solution in the first pipe 11 of the permeable manifold 1 can be quickly discharged into the collection circulation cabinet 31 through the first recovery pipe 34 and the second recovery pipe 35.
[0050] The third interface 113 is located at the bottom of the first tube 11, and the fourth interface 114 is located at the top of the first tube 11. With such a configuration, the first recovery pipe 34 can always discharge the ammonia solution in the first tube 11 into the collection circulation cabinet 31. When the ammonia solution in the first tube 11 is higher than the fourth interface 114, the second recovery pipe 35 starts to work, and the ammonia solution in the first tube 11 is discharged from the first recovery pipe 34 and the second recovery pipe 35 to the collection circulation cabinet 31 at the same time. In addition, the height of the fourth interface 114 is lower than the height of the first interface 111, so that when the ammonia solution in the first tube 11 reaches the fourth interface 114, it can be discharged from the second recovery pipe 35, avoiding the ammonia solution from flowing back from the first interface 111 into the release tube 2.
[0051] The outlets of the first recovery pipe 34 and the second recovery pipe 35 are both immersed under the ammonia solution of the collection circulation cabinet 31, so as to prevent the ammonia gas in the first pipe 11 of the gas-permeable manifold 1 from entering the collection circulation cabinet 31 through the first recovery pipe 34 and the second recovery pipe 35. The first recovery pipe 34 includes a first U-shaped bend, and the second recovery pipe 35 includes a second U-shaped bend. In this way, the flow path of the ammonia solution entering the first recovery pipe 34 and the second recovery pipe 35 can be increased, so that the ammonia gas in the ammonia fuel can be better dissolved in water.
[0052] The collection circulation cabinet 31 is also provided with a water replenishment port 311 and a discharge port 312. When the ammonia content in the water of the collection circulation cabinet 31 reaches saturation, the ammonia solution in the collection circulation cabinet 31 can be discharged into a larger ammonia solution storage tank through the discharge port 312. Then, new water is added to the collection circulation cabinet 31 through the water replenishment port 311 to better recover the ammonia fuel in the first tube 11 of the permeable header 1.
[0053] The recovery system 3 also includes a second liquid level alarm 37 and a third liquid level alarm 38, which are arranged inside the collection circulation cabinet 31 in the vertical direction. When the ammonia solution in the collection circulation cabinet 31 is located at or exceeds the second liquid level alarm 37, the second liquid level alarm 37 can sound an alarm to remind the staff to discharge the ammonia solution in the collection circulation cabinet 31 into a larger ammonia solution storage tank. When the ammonia solution in the collection circulation cabinet 31 is lower than the third liquid level alarm 38, the third liquid level alarm 38 can sound an alarm to remind the staff to replenish new water in real time to ensure the recovery efficiency of ammonia. Of course, in other embodiments, the discharge port 312 and the water replenishment port 311 are both provided with an electric control valve. After the second liquid level alarm 37 and the third liquid level alarm 38 sound an alarm, the signal can also be directly transmitted to the control system of the ship, and then the control system controls the opening and closing of the electric control valve, which can also achieve the above effect. It should be noted that the new water can be fresh water or seawater, as long as it can dissolve ammonia.
[0054] In order to maintain the inert environment in the collection circulation cabinet 31 , the collection circulation cabinet 31 is provided with an inert gas interface 313 , which is connected to an inert gas supply device for replenishing inert gas into the collection circulation cabinet 31 to maintain the inert environment inside the collection circulation cabinet 31 .
[0055] The recovery system 3 further includes a ventilation pipe 36, one end of which is connected to the second pipe 12, and the other end of which is connected to the top of the collection circulation cabinet 31. When the pressure in the collection circulation cabinet 31 is too high, the inert gas in the collection circulation cabinet 31 can be discharged into the second pipe 12 of the ventilation manifold 1 through the ventilation pipe 36, and then discharged from the second pipe 12. Preferably, the collection circulation cabinet 31 is provided with a ventilation interface, which is connected to the ventilation pipe 36 through a ventilation valve, and the ventilation valve has an open state and a closed state, so that the ventilation valve can be opened or closed as needed.
[0056] Figure 2 Shows Figure 1 The cross-sectional view at AA in the figure. Figure 2 Combination Figure 1 As shown, the spray pipe group 33 includes a main pipe 331, an annular pipe 332 and a nozzle 333. The main pipe 331 is used to connect the circulation pump 32 and the annular pipe 332. The annular pipe 332 is sleeved outside the first pipe 11. A plurality of nozzles 333 are connected to the ring of the annular pipe 332 at intervals along the circumference of the annular pipe 332. The nozzles 333 extend into the first pipe 11 through the second interface 112. In this way, all-round spraying can be achieved on the circumference of the first pipe 11 to improve the ammonia recovery efficiency. The number and arrangement of the nozzles 333 on the annular pipe 332 can be determined according to the diameter of the first pipe 11, and are not limited here.
[0057] In order to improve the ammonia recovery efficiency, multiple ring pipes 332 are connected to the main pipe 331 in parallel and at intervals, and the inlet of the main pipe 331 is connected to the circulation pump 32. The multiple ring pipes 332 are arranged in parallel, and the water pumped by the circulation pump 32 enters the main pipe 331, and then enters the multiple ring pipes 332 at the same time through the main pipe 331, which can improve the spraying effect and thus increase the amount of ammonia dissolved. The number of ring pipes 332 can be determined according to the length of the first pipe 11, and is not limited here.
[0058] The breathable mast device provided in this embodiment has an ammonia recovery function. It uses the characteristic that ammonia is easily soluble in water. For example, 1 volume of water can absorb 700 volumes of ammonia. The release pipe 2 is connected to the outside world through the breathable manifold 1, and then the recovery system 3 is used to form a closed water circulation system with the breathable manifold 1. The released ammonia can be continuously absorbed to ensure the safety of ammonia fuel used in ships. The breathable mast device can be flexibly arranged in various areas of the ship without meeting the height requirement of 1 / 3 of the ship width. The breathable mast device with ammonia recovery function has the function of absorbing ammonia by water spraying through a reasonable design, avoiding the release of ammonia into the atmosphere through the breathable mast, which is more environmentally friendly. At the same time, the design and layout of the breathable mast device are more flexible, suitable for almost all types of ships, and can provide ammonia ventilation solutions for ammonia fuel ships, solving the problem that ammonia fuel has a low flash point, is flammable and explosive, toxic and volatile, and cannot be safely used in ships.
[0059] This embodiment also provides a ship, comprising the above-mentioned ship-use breathable mast device. By using the above-mentioned ship-use breathable mast device, the ship can reduce the risk of ammonia poisoning of the crew and improve the safety of the ship.
