Description

Technical Field

[0001] This utility model relates to the field of inert gas generation technology, and in particular to an inert gas generator for oil tankers with a stable structure. Background Technology

[0002] As is well known, inert gas generators are key equipment for ensuring safety during oil tanker transportation. They generate inert gas, mainly nitrogen, through a specific process, and fill the cargo oil tanks and other areas of the oil tanker with it to reduce the oxygen concentration inside the tank and suppress the risk of oil and gas explosions. With the development of the shipping industry, the scale and frequency of oil tanker transportation are constantly increasing, which puts forward higher requirements for the stability and reliability of inert gas generators. Developing an inert gas generator for oil tankers with a stable structure is of great significance for ensuring the safe transportation of oil tankers and improving shipping efficiency.

[0003] Existing inert gas generators have drawbacks such as unreasonable structural design, high energy consumption, and certain environmental pollution.

[0004] An existing patent (publication number: CN205205081U) discloses an energy-saving and environmentally friendly inert gas generator for cleaning wastewater storage bodies. This inert gas generating device consists of a gasifier, a lower steam inlet pipe, an upper steam inlet pipe, and an inert gas collection tank. The gasifier has a lower steam inlet pipe, a lower air inlet pipe, and a lower exhaust valve at the bottom, and an upper steam inlet pipe and an upper exhaust valve at the top. Pipes at the top of the gasifier connect sequentially to a spray purification tank and the inert gas collection tank. Pipes at the bottom of the spray purification tank connect sequentially to a filter device, a heat exchange device, and the water jacket inlet of the gasifier. The water jacket outlet connects sequentially to a circulating pump and a water distribution plate inside the spray purification tank. The inert gas collection tank has a gas output at the top. This energy-saving and environmentally friendly inert gas generator for cleaning wastewater storage bodies has a simple structure, low energy consumption, and almost zero pollution to the environment. It also achieves rational energy utilization, is energy-saving and environmentally friendly, highly efficient, improves fuel combustion rate, and reduces costs.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, when preparing inert gases, the lack of a structure for automatically collecting and cleaning impurities within the inert gas makes it impossible to automatically clean and remove impurities, thus reducing the flexibility in handling impurities within the inert gas.

[0006] To address this, an inert gas generator for oil tankers with a stable structure is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an inert gas generator for oil tankers with a stable structure, which can solve the problem that existing inert gas preparation methods lack an automatic structure for centralized cleaning of impurities in the inert gas, thus reducing the flexibility of impurity treatment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an inert gas generator for oil tankers with a stable structure, comprising an inert gas generator body, a separation mechanism, and a processing mechanism, wherein the separation mechanism is located on the top of the inert gas generator body, and the processing mechanism is located inside the separation mechanism;

[0009] The separation mechanism includes an inlet pipe, a reaction pipe, an interceptor plate, a recovery pipe, and a storage pipe. The inlet pipe is connected to the top of the inert gas generator body, the reaction pipe is connected to the top of the inlet pipe, the interceptor plate is snapped into the inside of the reaction pipe, the recovery pipe is connected to the bottom of the inside of the interceptor plate, the storage pipe is connected to the surface of the recovery pipe, and the side of the storage pipe away from the recovery pipe passes through the reaction pipe and is welded to the reaction pipe.

[0010] Preferably, the processing mechanism includes a positioning component and a cleaning component, wherein the positioning component is disposed inside the inlet tube and the cleaning component is disposed inside the positioning component.

[0011] Preferably, the positioning assembly includes a processing tube, a positioning plate, and a conveying plate. The processing tube is connected to the top of the reaction tube, the positioning plate is fixedly connected to the top of the inner side of the processing tube, and the conveying plate is fixedly connected to the bottom of the inner side of the processing tube.

[0012] Preferably, the cleaning assembly includes a guide rod, a flow-following spiral plate, and a concentrated spiral mesh plate. The guide rod is rotatably connected to the bottom of the positioning plate, the flow-following spiral plate is welded to the surface of the guide rod, and the concentrated spiral mesh plate is snapped onto the surface of the flow-following spiral plate. The bottom of the concentrated spiral mesh plate is close to the top of the interception mesh plate.

[0013] Preferably, a discharge box is snapped onto the side of the storage tube away from the reaction tube, and a sealing sleeve is provided on the inner side of the discharge box, with the inner side of the sealing sleeve in contact with the surface of the reaction tube.

[0016] Preferably, a spiral reinforcing plate is fixedly connected to the surface of the flow-following spiral plate, and the surface of the spiral reinforcing plate is engaged with the inner side of the concentrated spiral mesh plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up an inert gas generator body and a separation mechanism. The inert gas generator body is an existing inert gas generating device that can prepare the fed raw material gas into inert gas. The separation mechanism can transport the raw material gas through the raw material gas conveying device connected to the processing mechanism. After the processing mechanism processes the raw material gas, the impurities after processing are introduced into the recovery pipe through the interception of the interception screen plate and finally transported into the storage pipe for storage, so as to facilitate subsequent recovery and cleaning. Then, the processed raw material gas is supplied to the inert gas generator body through the inlet pipe, which improves the flexibility of real-time discharge of impurities in the raw material gas.

[0019] 2. This application, by setting up a processing mechanism, allows the positioning component to cooperate with the cleaning component. By connecting the raw material gas conveying equipment to the processing pipe, the raw material gas can be conveyed into the processing pipe. When the positioning plate and the conveying plate limit the guide rod, the flowing spiral plate drives the guide rod to rotate together with the flowing gas, causing the concentrated spiral mesh plate to rotate. During rotation, the concentrated spiral mesh plate, through its own spiral design, can continuously guide impurities in the gas to the flowing spiral plate, thereby filtering impurities in the raw material gas and improving the stability of the raw material gas during subsequent preparation in the inert gas generator.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 The present invention provides the following technical solution:

[0028] An inert gas generator for oil tankers with a stable structure includes an inert gas generator body 1, a separation mechanism 2, and a processing mechanism 3. The separation mechanism 2 is located on the top of the inert gas generator body 1, and the processing mechanism 3 is located inside the separation mechanism 2.

[0029] The separation mechanism 2 includes an inlet pipe 21, a reaction pipe 22, an interception plate 23, a recovery pipe 24, and a storage pipe 25. The inlet pipe 21 is connected to the top of the inert gas generator body 1, the reaction pipe 22 is connected to the top of the inlet pipe 21, the interception plate 23 is snapped into the inside of the reaction pipe 22, the recovery pipe 24 is connected to the bottom of the inside of the interception plate 23, and the storage pipe 25 is connected to the surface of the recovery pipe 24. The side of the storage pipe 25 away from the recovery pipe 24 passes through the reaction pipe 22 and is welded to the reaction pipe 22.

[0030] In this embodiment: by setting an inert gas generator body 1 and a separation mechanism 2, the inert gas generator body 1 is an existing inert gas generating device that can prepare the fed raw material gas into inert gas. The separation mechanism 2 can use the raw material gas conveying device connected to the processing mechanism 3 to transport the raw material gas. After being processed by the processing mechanism 3, the processed impurities are introduced into the recovery pipe 24 through the interception of the interception plate 23, and finally transported into the storage pipe 25 for storage, so as to facilitate subsequent recovery and cleaning. Then, the processed raw material gas is provided to the inert gas generator body 1 through the inlet pipe 21, which improves the flexibility of real-time discharge of impurities in the raw material gas.

[0031] Specifically, such as Figure 3As shown, the processing mechanism 3 includes a positioning component 31 and a cleaning component 32. The positioning component 31 is located inside the inlet pipe 21, and the cleaning component 32 is located inside the positioning component 31.

[0032] Specifically, such as Figure 4 As shown, the positioning assembly 31 includes a processing tube 311, a positioning plate 312, and a conveying plate 313. The processing tube 311 is connected to the top of the reaction tube 22, the positioning plate 312 is fixedly connected to the top of the inner side of the processing tube 311, and the conveying plate 313 is fixedly connected to the bottom of the inner side of the processing tube 311.

[0033] Specifically, such as Figure 5 As shown, the cleaning component 32 includes a guide rod 321, a flow-following spiral plate 322, and a concentrated spiral mesh plate 323. The guide rod 321 is rotatably connected to the bottom of the positioning plate 312. The flow-following spiral plate 322 is welded to the surface of the guide rod 321. The concentrated spiral mesh plate 323 is snapped onto the surface of the flow-following spiral plate 322. The bottom of the concentrated spiral mesh plate 323 is close to the top of the interception mesh plate 23.

[0034] In this embodiment: by setting up the processing mechanism 3, the positioning component 31 can cooperate with the cleaning component 32. The raw material gas can be transported into the processing pipe 311 through the external raw material gas conveying equipment. When the positioning plate 312 and the conveying plate 313 limit the guide rotating rod 321, the flowing spiral plate 322 drives the guide rotating rod 321 together with the flowing gas to rotate the concentrated spiral mesh plate 323. When rotating, the concentrated spiral mesh plate 323 can continuously guide impurities in the gas to the flowing spiral plate 322 through its own spiral design, thereby filtering impurities in the raw material gas and improving the stability of the raw material gas in the subsequent preparation in the inert gas generator body 1.

[0035] Specifically, such as Figure 2 As shown, a discharge box 26 is snapped onto the side of the storage tube 25 away from the reaction tube 22. A sealing sleeve is provided on the inner side of the discharge box 26, and the inner side of the sealing sleeve is in contact with the surface of the reaction tube 22.

[0036] Specifically, such as Figure 2 As shown, a filter screen is attached to the side of the discharge box 26 away from the reaction tube 22. The filter screen is spherical.

[0037] In this embodiment: by setting up the discharge box 26, when it is necessary to remove the impurities stored in the storage tube 25, the discharge box 26 can be removed from the storage tube 25 to achieve the effect of removing and processing the impurities. In addition, the filter screen can discharge excess gas and intercept impurities when the discharge box 26 stores impurities.

[0038] Specifically, such as Figure 4As shown, a limiting plate 314 is fixedly connected to the bottom of the inner side of the conveyor plate 313, and the top of the limiting plate 314 is rotatably connected to the bottom of the guide rod 321.

[0039] Specifically, such as Figure 5 As shown, a spiral reinforcing plate 324 is fixedly connected to the surface of the flow-following spiral plate 322, and the surface of the spiral reinforcing plate 324 is engaged with the inner side of the concentrated spiral mesh plate 323.

[0040] In this embodiment: by setting a limiting plate 314 and a spiral reinforcing plate 324, the limiting plate 314 can provide auxiliary support for the bottom of the guide rod 321, thereby increasing the stability of the guide rod 321 during rotation. The spiral reinforcing plate 324 can provide auxiliary reinforcement for the connection between the flowing spiral plate 322 and the concentrated spiral mesh plate 323, further increasing the stability of the concentrated spiral mesh plate 323 on the flowing spiral plate 322, and improving the stability when the flowing spiral plate 322 drives the concentrated spiral mesh plate 323 to rotate.

[0041] First, a raw material gas conveying device is connected to the top of the processing pipe 311. Then, the raw material gas conveying device will transport the raw material gas through the processing pipe 311 to the inside of the reaction pipe 22. Then, the flowing spiral plate 322 will rotate along the guide rod 321 with the flowing gas, driving the concentrated spiral mesh plate 323 to rotate. When the concentrated spiral mesh plate 323 rotates, it will intercept impurities in the raw material gas and gradually guide the impurities to the recovery pipe 24 through its spiral design. The impurities remaining in the raw material gas after passing through the concentrated spiral mesh plate 323 will be intercepted by the intercepting mesh plate 23 and gradually move to the recovery pipe 24 with the flowing gas. Finally, it can be transported to the storage pipe 25 for storage through the recovery pipe 24. The processed raw material gas will flow into the inert gas generator body 1 through the reaction pipe 22 and the inlet pipe 21. Finally, the inert gas is prepared by the inert gas generator body 1.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
