DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] It is considered that the existing fuel filling anti-leakage technology for ships is mainly designed for traditional fuel and liquefied natural gas (LNG). In terms of anti-leakage of traditional fuel for ships, the existing technology mainly adopts internal protection method, including sealing detection, filter protection, emergency shutdown, continuous monitoring, leakage removal, etc. In the preparation and testing process before filling, a sealing detection device is used to test the pressure of the connecting pipeline to confirm that no leakage occurs. A filter or screen is installed at the filling end to prevent foreign matter from entering. During the filling process, an agreement is reached with the supplier on the maximum transmission rate, and the liquid level and pressure are continuously monitored in combination with the fuel tank pressure limiting valve capacity. When leakage occurs, personnel can use the ship-to-ship connection system (SSL) to shut down the fuel delivery pump, use the emergency shutdown (ESD) system to close the remote control valve of the filling pipeline system, and immediately use the on-site cleaning equipment to clean up the leakage and prepare the fire-fighting equipment to prevent fire.

[0024] In the aspect of LNG fuel filling anti-leakage technology for ships, cold box ventilation, combustible gas alarm, receiving and guiding, water curtain protection, etc. are mainly set. Cold box ventilation refers to a gas-tight place of a joint, a valve, a gasification device, etc. of a fuel cabin enclosure made of low-temperature resistant material to accommodate leaked LNG and prevent low-temperature damage to the ship structure. A combustible gas detector is arranged in the cold box to issue an alarm or take safety action before reaching the lower explosive limit (LEL) of natural gas. The receiving and guiding system is arranged directly below the low-temperature valve or the accessory prone to leakage to prevent the leaked LNG from directly contacting the ship structure and is provided with a guiding groove to guide the leaked LNG to a safe area. The water curtain protection is to use a water curtain for fire separation when LNG fire occurs, reduce fire heat radiation damage, protect personnel and facility safety, cool the fire boundary and prevent fire spread.

[0025] Under the policy of green and low-carbon transformation of global shipping industry, new fuels such as methanol and ammonia have begun to be applied in commercial ships, and the application scale is rapidly expanding. Popular ports along the coast of China such as Shanghai Port, Guangzhou Port and Dalian Port have carried out or are exploring the business of filling ships with methanol and ammonia fuels. However, the physicochemical properties and hazardous characteristics of methanol and ammonia fuels are quite different from those of traditional fuels and LNG. In particular, compared with traditional fuels, methanol and ammonia have strong volatility and toxicity, and leakage into the sea or volatilization into the air will pose a serious threat to personnel safety and the ecological environment. Therefore, the leakage protection of such new fuels not only needs to consider liquid phase pollution protection, but also needs to consider gas phase pollution protection caused by liquid phase leakage. Therefore, the anti-leakage device needs to have high-efficiency suction and transfer capacity for both liquid phase and gas phase.

[0026] Generally, the combination formed after the oil filling ship and the oil receiving ship are docked can be regarded as a system. The anti-leakage technology for traditional fuel for ships and the LNG fuel filling anti-leakage technology for ships mainly prevent leakage from the perspective of the shore-based filling station and ensure that the relevant pipelines of the filling station are promptly cut off after leakage occurs, but the gas phase and liquid phase leakage at the filling interface is not considered comprehensively. This is because traditional fuel has low volatility and basically does not need to consider gas phase leakage protection at the interface, and even if LNG fuel leaks and volatilizes from the interface, it will not have a strong toxic effect on the surrounding environment and personnel. Therefore, the application of new fuels such as methanol and ammonia poses new challenges to the port shore-to-ship fuel filling leakage protection, and the utility model provides a technical solution to meet this challenge.

[0027] In the fuel filling operation of the ship at the port shore, the flange joint of the pipeline is the key point where the leakage is most likely to occur. This is because during the filling process, the ship at the port is inevitably subject to rolling and pitching due to the influence of wind and waves, and the flange joint is subjected to constantly changing forces. In addition, the flange joint is a temporary connection link between the shore and the ship, and is not an integrated structure, so its carrying capacity and sealing performance are relatively poor. Practice shows that, whether it is the shore-to-ship filling of traditional fuel and methanol and other normal temperature fuel, or the shore-to-ship filling of LNG, ammonia and other low-temperature fuel, there is a risk of leakage of the flange joint, and the relevant protection technology needs to be universal to reduce the development and application cost. However, the industry has not yet explored a high-efficiency leakage treatment device suitable for shore-to-ship filling and multi-fuel universal to prevent such leakage.

[0028] Therefore, mainly aiming at the problem of the joint damage and leakage risk existing in the fuel filling of the ship at the port shore, the utility model provides a port shore-to-ship clean fuel filling leakage treatment device, in particular to a centrifugal port shore-to-ship clean fuel filling leakage treatment device, which is sleeved outside the filling pipeline structure and keeps running during the fuel filling process, and is used for quickly removing the leaked liquid fuel and combustible gas when the pipeline interface leaks, thereby improving the safety of the clean fuel filling of the ship.

[0029] According to the embodiment of the utility model, a port shore-to-ship clean fuel filling leakage treatment device is provided. Referring to Figure 1 The structure schematic diagram of an embodiment of the device of the utility model. The port shore-to-ship clean fuel filling leakage treatment device is applied to the flange joint of the fuel filling pipeline between the port shore-based filling station and the oil receiving ship, and is used for preventing the leakage of the clean fuel filling of the ship; Figure 2 It is a structure schematic diagram of the centrifugal port shore-to-ship clean fuel filling leakage treatment device. As Figure 2 The centrifugal port shore-to-ship clean fuel filling leakage treatment device is sleeved outside the end of the fuel filling pipeline 1 and the periphery of the fuel filling pipeline flange 4 at the end of the fuel filling pipeline 1. In the scheme of the utility model, the arrangement mode of the peripheral sleeve is adopted, so that there is no connection structure between the centrifugal port shore-to-ship clean fuel filling leakage treatment device and the fuel filling pipeline 1, and the device can be widely used for various fuel types and gases, liquids and other fuels in different states, including ordinary diesel oil, LNG, methanol, ammonia, biofuel and the like. Although the port shore-to-ship clean fuel filling leakage treatment device is designed according to the physical and chemical properties and dangerous characteristics of methanol, ammonia and other new fuels, it is also compatible with the leakage protection of traditional fuel, LNG, biofuel and the like. The port shore-to-ship clean fuel filling leakage treatment device comprises a suction component (such as a magnetic cage type shaftless centrifugal suction device 3), a driving component (such as a rotating magnetic field generating coil 6), and a flow guide component (such as a flow guide component composed of a flow guide shell 5 and a flow guide pipeline).

[0030] The suction component is sleeved on the periphery of the flange joint of the fuel filling pipeline, and is used for sucking the fuel leaking at the flange joint of the fuel filling pipeline to the flow guide component in the case that the suction component works by itself; and the central axis of the suction component is parallel to or coincides with the fuel filling pipeline. Specifically, the suction component is used for sucking the fuel leaking at the flange joint of the fuel filling pipeline to the flow guide component from at least one of the two ends of the suction component.

[0031] The flow guide component is arranged on the periphery of the suction component, specifically between the suction component and the driving component, and is used for guiding the fuel sucked by the suction component to the flow guide component.

[0032] The driving component is used for generating driving force in the case of power supply, so as to drive the suction component to work by using the driving force. Preferably, the driving component is arranged on the periphery of the flow guide component.

[0033] The leakage prevention emergency protection device provided by the scheme of the utility model is a centrifugal type port shore-to-ship clean fuel filling leakage treatment device (such as a centrifugal type shore-to-ship fuel filling leakage treatment device), which has a hollow cylindrical overall shape, is sleeved on the periphery of a filling pipeline structure (such as a fuel filling pipeline flange 4), and keeps running during the fuel filling process, and is used for quickly removing the leaked liquid fuel and combustible gas when leakage occurs at a pipeline interface (such as the fuel filling pipeline flange 4), thereby improving the safety of ship clean fuel filling.

[0034] In some embodiments, the suction component comprises a centrifugal wind wheel component; the driving component comprises a magnetic driving component; and the magnetic driving component is arranged on the periphery of the flow guide component and is used for generating magnetic force in the case of power supply, so as to drive the centrifugal wind wheel component to rotate by using the magnetic force as the driving force. Figure 2 As shown in the examples, the centrifugal type port shore-to-ship clean fuel filling leakage treatment device adopts a centrifugal airflow guiding principle, has good capturing effect on combustible gas and leaked fuel, and can continuously run and protect during the filling process.

[0035] In some embodiments, the centrifugal wind wheel component comprises a magnetic cage type shaftless centrifugal suction device 3; and the suction component further comprises a pair of rolling bearings; the magnetic cage type shaftless centrifugal suction device 3 is sleeved on the periphery of the flange joint of the fuel filling pipeline; and the pair of rolling bearings are arranged on the outer rings at the two axial ends of the magnetic cage type shaftless centrifugal suction device 3.

[0036] Referring toFigure 2 In the example shown, the designed speed-adjustable magnetic-cage shaftless centrifugal suction device 3 can simultaneously adapt to the capture of various types and various physical states of leaked fuel and flammable gas, and has strong versatility. By changing the rotation speed of the magnetic-cage shaftless centrifugal suction device 3, the suction flow rate can be changed to adapt to different fuel leakage amounts.

[0037] In some embodiments, the driving component includes a rotating magnetic field generating coil 6, and the flow guide component includes a flow guide shell 5 and a flow guide pipeline.

[0038] Referring to Figure 2 In the example shown, the centrifugal port-side ship fuel filling leakage treatment device adopts an external magnetic field drive, and the electrical components do not contact the flammable gas, which essentially avoids the possibility of combustion and has an intrinsically safe feature. The indirect drive structure of the rotating magnetic field generator has the intrinsically safe feature that the driving system does not contact the flammable gas.

[0039] Specifically, the suction component includes a magnetic-cage shaftless centrifugal suction device 3 and a pair of rolling bearings, the driving component includes a rotating magnetic field generating coil 6, and the flow guide component includes a flow guide shell 5 and a flow guide pipeline.

[0040] The magnetic-cage shaftless centrifugal suction device 3 is sleeved around the flange joint of the fuel filling pipeline, and the pair of rolling bearings are arranged at the outer rings of the magnetic-cage shaftless centrifugal suction device 3 in the axial direction. The outer rings of the pair of rolling bearings are arranged on the inner wall of the flow guide shell 5, and the inner rings of the pair of rolling bearings are arranged on the outer wall of the magnetic-cage shaftless centrifugal suction device 3. The rotating magnetic field generating coil 6 is arranged around the flow guide shell 5 and can wrap the magnetic-cage shaftless centrifugal suction device 3. The flow guide shell 5 is arranged around the magnetic-cage shaftless centrifugal suction device 3 and wraps the magnetic-cage shaftless centrifugal suction device 3. The flow guide shell 5 forms an electrical isolation structure between the rotating magnetic field generating coil 6 and the magnetic-cage shaftless centrifugal suction device 3, and the flow guide pipeline is arranged at the outlet end of the flow guide shell 5.

[0041] In the scheme of the utility model, referring to Figure 2In the shown example, when the whole centrifugal port shore to the ship clean fuel filling leakage processing device starts to run, the rotating magnetic field generating coil 6 is connected with alternating current of certain frequency and wave form, so that the rotating magnetic field is generated, and the magnetic cage type shaftless centrifugal suction device 3 is driven to rotate around the shaft. In the process of rotating the magnetic cage type shaftless centrifugal suction device 3, the blades on the side of the cylindrical cage of the magnetic cage type shaftless centrifugal suction device 3 guide the airflow to the outside of the magnetic cage type shaftless centrifugal suction device 3, and the gas is sucked from the center of both ends of the magnetic cage type shaftless centrifugal suction device 3 (such as the gas is sucked from the gas flow direction 2) and is thrown out from the outside, and the thrown-out gas is collected by the flow guide shell 5 to the gas outlet and discharged. When the fuel filling pipeline 1 flange leaks, the leaked flammable gas will be sucked away with the airflow, and the leaked liquid fuel will be thrown into the flow guide shell 5 by the magnetic cage type shaftless centrifugal suction device 3, and discharged from the gas outlet (such as the gas liquid outlet 10).

[0042] In the scheme of the utility model, see Figure 2 In the shown example, the outer ring of the magnetic cage type shaftless centrifugal suction device 3 is provided with a set of large-diameter rolling bearings, the bearing outer ring of the rolling bearing is fixed to the flow guide shell 5, and the bearing inner ring of the rolling bearing is fixed to the magnetic cage type shaftless centrifugal suction device 3, so as to ensure that the magnetic cage type shaftless centrifugal suction device 3 cooperates with the flow guide shell 5 and can realize shaftless rotation of the magnetic cage type shaftless centrifugal suction device 3. In the scheme of the utility model, the outer sleeve type centrifugal suction structure can realize 360-degree omnidirectional suction around the flange (such as the fuel filling pipeline flange 4) joint, so as to ensure better suction effect.

[0043] Optionally, the arrangement of the rotating magnetic field generating coil 6 can be different. In order to realize the effect of the magnetic cage type shaftless centrifugal suction device 3, the rotating magnetic field generating coil 6 needs to be arranged on the periphery of the magnetic cage type shaftless centrifugal suction device 3 and completely wrap the magnetic cage type shaftless centrifugal suction device 3. At the same time, in order to realize intrinsic safety, the rotating magnetic field generating coil 6 needs to be arranged outside the flow guide shell 5 and isolated from the flammable gas. Therefore, the arrangement of the rotating magnetic field generating coil 6 is related to the shape structure of the flow guide shell 5, and there can be many deformation structures according to different shapes of the flow guide shell 5, but the core function is to drive the magnetic cage type shaftless centrifugal suction device 3.

[0044] Optionally, the shape structure of the flow guide shell 5 can be different. In order to realize the effect of flow guide, the flow guide shell 5 needs to be arranged on the periphery of the magnetic cage type shaftless centrifugal suction device 3 and completely wrap the magnetic cage type shaftless centrifugal suction device 3. According to different required flow guide flow, the size of the flow guide shell 5 can be different. In addition, according to different flow guide directions (or the gas liquid outlet 10), the flow guide shell 5 can be designed into different shapes.

[0045] In some embodiments, the magnetic cage type shaftless centrifugal suction device 3 is formed in the shape of a cylindrical cage; the cylindrical cage comprises blades and an end face structure.

[0046] The central axis of the magnetic cage type shaftless centrifugal suction device 3 is parallel to or coincides with the fuel filling pipeline; the number of the blades is N, and the N blades are arranged at intervals along the axial direction of the magnetic cage type shaftless centrifugal suction device 3, and N is a positive integer; and the end face structure is located on the end face of the N blades and is used for fixing the N blades.

[0047] In Figure 2 In the example shown, the magnetic cage type shaftless centrifugal suction device 3 is made of magnetized metal or other magnetic material, and the shape of the magnetic cage type shaftless centrifugal suction device 3 is a cylindrical cage. The side surface of the cylindrical cage of the magnetic cage type shaftless centrifugal suction device 3 is composed of a plurality of blades, and the central axis of rotation of the magnetic cage type shaftless centrifugal suction device 3 is parallel to or coincides with the fuel filling pipeline 1.

[0048] In some embodiments, the N blades are arranged at a set angle along the axial direction of the magnetic cage type shaftless centrifugal suction device 3.

[0049] Alternatively, the structure of the magnetic cage type shaftless centrifugal suction device 3 can be different. In order to achieve the effect of centrifugal suction, the blade layout of the magnetic cage type shaftless centrifugal suction device 3 can be parallel to the radial direction or at a certain angle.

[0050] In some embodiments, the N blades are arranged at a set angle along the axial direction of the magnetic cage type shaftless centrifugal suction device 3.

[0051] Alternatively, the number of blades of the magnetic cage type shaftless centrifugal suction device 3 can also be different according to different required suction effects. In addition, the blades can also be designed to be curved, which does not hinder the formation of a certain suction effect.

[0052] In some embodiments, the surface of the end face structure has at least one of the following structures: an opening structure, a bending structure, and a groove structure.

[0053] Alternatively, in addition to the blades, the circular end face structure design for fixing the blades at both ends of the magnetic cage type shaftless centrifugal suction device 3 can also be different, such as surface opening, shape bending, surface groove, etc., but does not affect the main function of fixing the blades. Among them, the surface opening and the surface groove can reduce the weight of the rotor and reduce the power consumption of the system; the shape bending helps to improve the structural strength of the end face of the rotor, which plays a role similar to a reinforcing rib.

[0054] In some embodiments, the port shore-to-ship clean fuel filling leakage treatment device further comprises a collecting component; wherein the collecting component is arranged at the outlet of the flow guide component and is used for collecting the fuel guided by the flow guide component.

[0055] InFigure 2 In the example shown, the fuel filling pipeline 1 is the protected object. The main function of the rotating magnetic field generating coil 6 is to generate a rotating magnetic field to drive the magnetic caged shaftless centrifugal suction device 3 to rotate. The function of the magnetic caged shaftless centrifugal suction device 3 is to suck and remove the leaked fuel and flammable gas. The function of the flow guide shell 5 is to guide the leaked fuel and flammable gas into the collection component, and the collected leaked gas or liquid fuel can be recovered to an external container for storage and reuse. The collection device can be a container such as a bucket, a box, or a special cabin welded; the collection device can be directly connected with the flow guide shell 5 by a pipeline, and the pipeline should be arranged to ensure that the fuel can smoothly enter the collection device without backflow.

[0056] In some embodiments, the port shore-based ship clean fuel filling leakage treatment device further comprises a gas concentration detection component (such as a flammable gas concentration detector 9) and an inert gas injection component (such as an inert gas injection pipe 7).

[0057] The gas concentration detection component is arranged inside the flow guide component and is used to detect the concentration of flammable gas inside the flow guide component.

[0058] The injection inlet of the inert gas injection component extends into the flow guide component, and is used to inject inert gas into the flow guide component when the concentration of flammable gas detected by the gas concentration detection component is higher than a preset gas concentration threshold, so as to prevent the explosion of flammable gas inside the port shore-based ship clean fuel filling leakage treatment device when the concentration of flammable gas inside the flow guide component is higher than the preset gas threshold.

[0059] In Figure 2 In the example shown, the flammable gas concentration detector 9 is used to continuously detect the concentration of flammable gas inside the flow guide shell 5, and the inert gas injection pipe 7 is used to inject inert gas into the flow guide shell 5 when necessary to prevent the explosion of flammable gas.

[0060] Referring to Figure 2 In the example shown, to prevent the deflagration of flammable gas in the flow guide pipeline (such as the pipeline where the gas and liquid outlet 10 is located), the centrifugal port shore-based ship clean fuel filling leakage treatment device is provided with a flammable gas concentration detector 9 and an inert gas injection pipe 7, so that when the concentration of flammable gas detected by the flammable gas concentration detector 9 reaches the explosion limit range, inert gas is injected into the flow guide pipeline through the inert gas injection pipe 7 to reduce the oxygen content in the mixed gas and reduce the risk of deflagration.

[0061] In some embodiments, the port shore-to-ship clean fuel filling leakage treatment device further comprises a fire-fighting foam injection component (such as a fire-fighting foam injection pipe 8); wherein an injection inlet of the fire-fighting foam injection component extends into the flow guide component, such as extending into the flow guide component, for injecting fire-fighting foam into the flow guide component in the event of combustion of combustible gas inside the flow guide component, and timely injecting fire-fighting foam to extinguish the fire.

[0062] In Figure 2 the example shown, the fire-fighting foam injection pipe 8 functions to timely inject fire-fighting foam to extinguish the fire in the event of accidental combustion of leaked fuel and combustible gas inside the centrifugal port shore-to-ship clean fuel filling leakage treatment device.

[0063] Referring to Figure 2 the example shown, to prevent accidental combustion of liquid fuel collected by the centrifugal port shore-to-ship clean fuel filling leakage treatment device, the centrifugal port shore-to-ship clean fuel filling leakage treatment device is provided with a fire-fighting foam injection pipe 8 for injecting fire-fighting foam into the centrifugal port shore-to-ship clean fuel filling leakage treatment device through the fire-fighting foam injection pipe 8.

[0064] In the scheme of the present application, to prevent combustion caused by other external factors, the centrifugal port shore-to-ship clean fuel filling leakage treatment device is further provided with an inert gas injection device (such as an inert gas injection pipe 7) and a fire-fighting foam injection component (such as a fire-fighting foam injection pipe 8) to further ensure safety. The use of a gas concentration sensor in combination with inert gas injection, fire-fighting foam injection and other fire extinguishing and explosion suppression methods can automatically adjust the fire extinguishing and explosion suppression according to the changes in combustible gas. The installation relationship between the inert gas injection pipe 7, the fire-fighting foam injection pipe 8, the combustible gas concentration detector and the flow guide shell 5 may Figure 2 be different, but the functions are the same.

[0065] As Figure 2 shown, the centrifugal port shore-to-ship clean fuel filling leakage treatment device comprises a magnetic cage type shaftless centrifugal suction device 3, a flow guide shell 5, a rotating magnetic field generating coil 6, an inert gas injection pipe 7, a fire-fighting foam injection pipe 8, a combustible gas concentration detector 9, and a gas and liquid outlet 10, which cooperate with each other and are linked together to ensure that the centrifugal port shore-to-ship clean fuel filling leakage treatment device achieves the required functions and ensures safety.

[0066] To verify Figure 2 the effect of the centrifugal port shore-to-ship clean fuel filling leakage treatment device shown in ​The centrifugal port shore-to-ship clean fuel filling leakage treatment device is shown in Table 1. The greater the fuel leakage, the greater the required speed.

[0068]

[0069] In the scheme of the utility model, the centrifugal port shore-to-ship clean fuel filling leakage treatment device mainly comprises a magnetic cage type shaftless centrifugal suction device 3, a flow guide shell 5, a rotating magnetic field generating coil 6, an inert gas injection pipe 7, a fire-fighting foam injection pipe 8, a combustible gas concentration detector 9 and the like. When the centrifugal port shore-to-ship clean fuel filling leakage treatment device is running, the rotating magnetic field generating coil 6 is electrified to continuously generate a rotating magnetic field with certain parameters, which drives the magnetic cage type centrifugal suction device (such as the magnetic cage type shaftless centrifugal suction device 3) to rotate at a certain speed, so as to ensure that the leakage is quickly sucked and removed when the leakage occurs, and the safety of the clean fuel filling for ships is improved. In addition, during the running of the centrifugal port shore-to-ship clean fuel filling leakage treatment device, the combustible gas concentration detector 9 is in a continuous working state. When the combustible gas concentration detector 9 detects that the combustible gas concentration reaches the explosion limit, the inert gas injection pipe 7 starts to work to inject inert gas into the flow guide shell 5, so as to reduce the explosion risk and further improve the safety of the clean fuel filling for ships. Furthermore, when the combustible material in the flow guide shell 5 is accidentally ignited, the fire-fighting foam injection pipe 8 starts to work and injects fire-fighting foam into the flow guide shell 5, so as to inject fire-fighting foam in time to extinguish the fire when the leakage fuel and combustible gas in the centrifugal port shore-to-ship clean fuel filling leakage treatment device are accidentally combusted, and further improve the safety of the clean fuel filling for ships.
