Description

Technical Field

[0001] The invention belongs to the field of petrochemical industry, and in particular relates to a petrochemical double-layer storage tank. Background Art

[0002] The petrochemical industry plays an important role in modern industry and is widely used in many fields such as energy, materials, cosmetics, medicine, pesticides, coatings, plastics, etc.

[0003] Petrochemical storage tanks are containers used to store raw materials, intermediate products and finished products during the petrochemical production process. These tanks are usually made of metal (such as steel) or concrete and have different shapes and capacities to suit various storage needs. The main function of a storage tank is to safely store liquids or gases, and it plays a role in storing, regulating and distributing substances in the petrochemical process.

[0004] Petrochemical storage tanks can be divided into many types according to their uses and properties, such as raw material storage tanks, intermediate product storage tanks, finished product storage tanks, storage and transportation tanks, etc. These tanks need to have a series of safety measures to prevent accidents such as leakage, spontaneous combustion, and explosion. Common safety measures include leak detection systems, fire and explosion prevention devices, temperature and pressure monitoring systems, etc. In addition, storage tanks also need to be inspected and maintained regularly to ensure their structural integrity and safety performance.

[0005] Current oil storage tanks have a number of problems when leaks occur, the most notable of which is the inability to handle leaks in a timely manner. Due to the lack of effective leak detection and control measures, leaks may continue to occur, resulting in the inability to stop the flow of oil reserves in time, further increasing the scale and duration of the leak. This delayed handling will cause serious pollution and damage to the environment and may pose a threat to the safety of personnel.

[0006] At the same time, the leaked oil storage will cause high temperature problems, which greatly increases the risk of spontaneous combustion of oil in the tank. Since oil is a flammable substance, once spontaneous combustion occurs, it will cause serious safety accidents such as fire and explosion. The risk of spontaneous combustion caused by this high temperature will not only damage the tank itself, but also cause further harm to the surrounding facilities and environment. Summary of the invention

[0007] The purpose of the present invention is to provide a petrochemical double-layer storage tank, which aims to solve a series of problems in current oil storage tanks when leaking, the most notable of which is the inability to handle the leak in time. Due to the lack of effective leak detection and control measures, the leak may continue to occur, resulting in the failure to stop the oil storage material from flowing out in time, further increasing the scale and duration of the leak. This delayed handling will cause serious pollution and damage to the environment and may pose a threat to the safety of personnel.

[0008] At the same time, the leaked oil storage will cause high temperature problems, which greatly increases the risk of spontaneous combustion of oil in the tank. Since oil is a flammable substance, once spontaneous combustion occurs, it will cause serious safety accidents such as fire and explosion. The risk of spontaneous combustion caused by this high temperature will not only damage the tank itself, but also cause further harm to the surrounding facilities and environment.

[0009] The present invention is implemented as follows: a petrochemical double-layer storage tank comprises: a support platform, a support leg is arranged on the support platform, a storage tank is installed at one end of the support leg, a feed port is arranged on the storage tank, the storage tank comprises an inner storage tank and an outer storage tank, a limiting sealing component is arranged between the inner storage tank and the outer storage tank, and the limiting sealing component is used to perform secondary sealing and isolation on the outer surface of the inner storage tank when leakage of the inner storage tank is detected;

[0010] The isolation and cooling component is arranged between the inner storage tank and the outer storage tank. The isolation and cooling component is used to start after the limiting and sealing component completes the secondary sealing and isolation of the inner storage tank, continuously spray and cool the inner storage tank, and decompose the leaked storage material.

[0011] As a further solution of the present invention, the limiting sealing component includes:

[0012] A group of intermittent curved grooves are symmetrically opened at both ends of the inner wall of the outer storage tank, and guide curved rods are fixedly arranged in the intermittent curved grooves;

[0013] A curved groove slider is slidably disposed in the intermittent curved groove, and the curved groove slider is slidably connected to the guide curved rod, and the guide curved rod is used to limit the movement trajectory of the curved groove slider;

[0015] A fixed rod, mounted on each of the curved groove sliders;

[0016] A winding roller shaft is rotatably connected between the oppositely arranged fixed rods, and a closed curtain is wound around the winding roller shaft;

[0017] An arc-shaped bearing plate is mounted on the top wall of the inner storage tank, and the end of the closed curtain that is not connected to the winding roller is connected to the arc-shaped bearing plate;

[0018] The leakage sensor is arranged on the inner wall of the outer storage tank, and the leakage sensor is used to send a start signal to the power guide wheel when the leakage sensor detects that there is stored material in the outer storage tank.

[0019] As a further solution of the present invention, the closed curtain fabric is a double-layer curtain fabric, the inner layer of which is a carbonized fiber cloth, and the outer layer is covered with a waterproof coating, and the inner layer is a glass fiber cloth.

[0020] As a further solution of the present invention, the structure of the fixed rod is an elastic rod, and the length of the elastic rod in a natural state is not less than the radius difference between the inner storage tank and the outer storage tank.

[0024] As a further embodiment of the present invention, the substance stored in the water storage container is a water-oxidant mixed liquid.

[0025] As a further solution of the present invention, the power guide wheel sends a start signal to the spray pump after starting and allowing the closing curtain to completely cover the inner storage tank.

[0026] The petrochemical double-layer storage tank provided by the present invention has the following beneficial effects:

[0027] When the petrochemical double-layer storage tank is in use, the oil reserves will be stored in the inner storage tank. If the inner storage tank leaks, the leaked reserves will first enter the outer storage tank. The restricted sealing component in the outer storage tank will detect in real time whether there is oil reserves in the outer storage tank, so as to determine whether there is a leak in the inner storage tank.

At the same time, the sealing and high-temperature resistant design can ensure that the inner tank will not leak after the covering material fits the inner tank. On the other hand, petroleum storage materials are high-temperature flammable products, and the high-temperature resistant design also improves durability.

[0029] After the covering material covers the inner tank, the isolation and cooling component will spray cooling liquid between the outer tank and the inner tank. The cooling liquid has the effect of decomposing the petroleum reserves, decomposing the petroleum reserves leaked between the outer tank and the inner tank, reducing the risk of spontaneous combustion. The cooling effect can also continue to cool the inner tank, further improving safety performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] like Figure 1 As shown, in an embodiment of the present invention, a petrochemical double-layer storage tank comprises: a support platform 1, a support leg 2 is arranged on the support platform 1, a storage tank 3 is installed at one end of the support leg 2, a feed port 4 is arranged on the storage tank 3, the storage tank 3 comprises an inner storage tank 5 and an outer storage tank 6, a limiting sealing component 7 is arranged between the inner storage tank 5 and the outer storage tank 6, and the limiting sealing component 7 is used to perform secondary sealing and isolation on the outer surface of the inner storage tank 5 when leakage is detected in the inner storage tank 5;

[0040] The isolation and cooling component 8 is arranged between the inner storage tank 5 and the outer storage tank 6. The isolation and cooling component 8 is used to start after the limiting and sealing component 7 completes the secondary sealing and isolation of the inner storage tank 5, continuously spray and cool the inner storage tank 5, and decompose the leaked storage material.

[0041] When the petrochemical double-layer storage tank is in use, the oil reserves will be stored in the inner storage tank 5. If the inner storage tank 5 leaks, the leaked reserves will first enter the outer storage tank 6. The limiting closure component 7 in the outer storage tank 6 will detect in real time whether there is oil reserves in the outer storage tank 6, so as to determine whether there is a leak in the inner storage tank 5.

[0042] When the inner tank 5 is identified to be leaking, the limiting closure assembly 7 will start to operate, covering the outer surface of the inner tank 5, and the covering material will be completely in contact with the surface of the inner tank 5. At the same time, the sealing and high-temperature resistant design can ensure that the inner tank 5 will not leak after the covering material is in contact with the inner tank 5. On the other hand, the petroleum storage material is a high-temperature flammable product, and the high-temperature resistant design also improves the durability.

[0043] After the inner storage tank 5 is covered with the covering material, the isolation and cooling component 8 will spray cooling liquid between the outer storage tank 6 and the inner storage tank 5, and the cooling liquid has the effect of decomposing the petroleum reserves, and the petroleum reserves leaked between the outer storage tank 6 and the inner storage tank 5 will be decomposed to reduce the risk of spontaneous combustion, and the cooling effect can also continue to cool the inner storage tank 5, further improving the safety performance.

[0044] like Figures 1 to 6 As shown, in the embodiment of the present invention, the limiting and sealing component 7 includes:

[0045] A set of intermittent curved grooves 9 are symmetrically opened at both ends of the inner wall of the outer storage tank 6, and a guide curved rod 10 is fixedly arranged in the intermittent curved grooves 9;

[0046] A curved groove slider 11 is slidably disposed in the intermittent curved groove 9, and the curved groove slider 11 is slidably connected to the guide curved rod 10, and the guide curved rod 10 is used to limit the movement trajectory of the curved groove slider 11;

[0047] The power guide wheel 12 is arranged on the curved groove slider 11, and the power guide wheel 12 and the inner wall of the intermittent curved groove 9 are in contact with each other;

[0048] A fixed rod 13, mounted on each of the curved groove sliders 11;

[0049] A winding roller 14 is rotatably connected between the oppositely arranged fixed rods 13, and a closed curtain 15 is wound around the winding roller 14;

[0050] An arc-shaped bearing plate 16 is mounted on the top wall of the inner storage tank 5, and one end of the closed curtain 15 that is not connected to the winding roller 14 is connected to the arc-shaped bearing plate 16;

[0051] The leakage sensor 17 is disposed on the inner wall of the outer storage tank 6 , and the leakage sensor 17 is used to send a start signal to the power guide wheel 12 when it detects that there is stored material in the outer storage tank 6 .

[0052] In the embodiment of the present invention, the closing curtain fabric 15 is a double-layer curtain fabric, the inner layer of which is a carbon fiber cloth, and the outer layer is covered with a waterproof coating, and the inner layer is a glass fiber cloth.

[0053] When in use, the leakage sensor 17 will detect in real time whether there is oil storage in the outer storage tank 6, so as to determine whether there is a leak in the inner storage tank 5. When the inner storage tank 5 is identified to be leaking, a start signal will be sent to the power guide wheel 12, and the power guide wheel 12 will start to rotate and drive the curved groove slider 11 to slide. When the curved groove slider 11 slides, it will drive the closed curtain 15 to move through the fixed rod 13 and the winding roller 14, so that the rolled closed curtain 15 is gradually spread on the surface of the inner storage tank 5, and the closed curtain 15 will fit the inner storage tank 5. The closed curtain 15 is a double-layer curtain, the inner layer is carbonized fiber cloth, and the outer layer is covered with a waterproof coating, and the inner layer is glass fiber cloth. This design can not only ensure that the closed curtain 15 can achieve secondary sealing of the inner storage tank 5 after being spread out, stop the leakage of the inner storage tank 5, but also has high temperature resistance and improves the service life.

[0054] In the embodiment of the present invention, the structure of the fixing rod 13 is an elastic rod, and the length of the elastic rod in a natural state is not less than the radius difference between the inner storage tank 5 and the outer storage tank 6 .

[0055] The design of the elastic rod can ensure that the fixed rod 13 can always push the closing curtain 15 to fit the inner storage tank 5, avoid a gap between the closing curtain 15 and the inner storage tank 5, and ensure the stability of the sealing and isolation effect.

[0056] like Figures 1 to 6 As shown, in this embodiment of the present invention, the isolation and cooling component 8 includes:

[0057] A water storage container 18 is disposed on the support platform 1, and water inlet pipelines 19 are disposed on both sides of the water storage container 18, and one end of the water inlet pipeline 19 extends to the inside of the outer storage tank 6;

[0058] A set of fixed bases 20 are symmetrically mounted on the inner wall of the outer storage tank 6 , and the water inlet pipeline 19 is connected to the fixed bases 20 . A plurality of spray pumps 21 are arranged on the fixed bases 20 , and the spray pumps 21 are connected to the water inlet pipeline 19 .

[0059] In the embodiment of the present invention, the substance stored in the water storage container 18 is a water-oxidant mixed liquid.

[0060] In the embodiment of the present invention, the power guide wheel 12 sends a start signal to the spray pump 21 after starting and allowing the closing curtain 15 to completely cover the inner storage tank 5 .

[0061] When in use, after the closing curtain 15 completely covers the inner storage tank 5, the power guide wheel 12 will be in the extreme state of movement. At this time, the power guide wheel 12 will send a start signal to the spray pump 21, and the spray pump 21 will start to absorb the liquid in the water storage container 18 and transport it to the inside of the outer storage tank 6 through the water inlet pipeline 19. The water-oxidant mixed liquid in the water storage container 18 is sprayed to the part between the outer storage tank 6 and the inner storage tank 5 by the spray pump 21. The water and the oxidant (such as hydrogen peroxide) are mixed to produce a certain chemical reaction, promote the oxidation and decomposition of oil, and reduce the temperature of the oil leakage area. This mixed liquid can be sprayed in the oil leakage area, decompose the oil through the oxidation reaction, and produce a cooling effect.

[0062] In summary, when the petrochemical double-layer storage tank is in use, the petroleum reserves will be stored in the inner storage tank 5, and if the inner storage tank 5 leaks, the leaked reserves will first enter the outer storage tank 6, and the limiting sealing component 7 in the outer storage tank 6 will detect in real time whether there is petroleum reserves in the outer storage tank 6, so as to determine whether there is a leak in the inner storage tank 5;

[0063] When the inner tank 5 is identified to be leaking, the limiting closure assembly 7 will start to operate, covering the outer surface of the inner tank 5, and the covering material will be completely in contact with the surface of the inner tank 5. At the same time, the sealing and high-temperature resistant design can ensure that the inner tank 5 will not leak after the covering material is in contact with the inner tank 5. On the other hand, the petroleum storage material is a high-temperature flammable product, and the high-temperature resistant design also improves the durability.

[0064] After the inner storage tank 5 is covered with the covering material, the isolation and cooling component 8 will spray cooling liquid between the outer storage tank 6 and the inner storage tank 5, and the cooling liquid has the effect of decomposing the petroleum reserves, and the petroleum reserves leaked between the outer storage tank 6 and the inner storage tank 5 will be decomposed to reduce the risk of spontaneous combustion, and the cooling effect can also continue to cool the inner storage tank 5, further improving the safety performance.

[0065] Leakage stop and control: When the inner layer leaks, using the closure curtain 15 to cover the inner layer can effectively stop the spread of the leaked oil and avoid further pollution and loss.

[0066] Liquids that break down oil: Spraying a water-oxidant mixture between the inner and outer layers breaks down the oil, converting it into non-flammable molecules. This reduces the amount of oil that leaks and avoids the risk of the oil catching fire or exploding at high temperatures.

[0067] Cooling effect: The use of water-oxidant mixed liquid can cool the oil spill area, reduce heat accumulation, and reduce the possibility of fire. This helps protect the safety of the storage tank 3 and nearby equipment, personnel, and the environment.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
