Description

Technical Field

[0001] The present invention relates to the technical field of fluid material storage and transportation, and in particular to an inverted cover type hydraulic bearing material storage device and method. Background Art

[0002] The mainstream form of existing fluid material storage and transportation equipment is the floating roof storage tank, which reduces the breathing loss of materials by moving the floating roof up and down. It is mainly divided into rigid tank structure and flexible bag container.

[0003] The rigid tank structure is mainly made of steel material, and the tank body is coated with anti-corrosion paint inside and outside to prevent corrosion. This storage and transportation method and device has the problems of complex structure, high cost, easy corrosion, poor safety, high maintenance cost, etc.

[0004] Flexible bag-type containers are made of flexible materials and have flexible structures that can be deformed and changed in volume. They are also called bladder containers. For example, deformable oil bags made of rubber are simple and lightweight, easy to deliver by aircraft, and can be used for military purposes such as battlefield fuel supply, temporary construction site oil supply, and temporary occasions such as offshore oil spill collection. The tank body of this storage device is made of flexible materials with a soft structure. It can be placed on a rigid foundation or floated in water bodies such as seawater. When used on a rigid foundation, it is not suitable for occasions with large storage capacity because of the low rigidity of the tank structure. When used on water bodies such as rivers, lakes, and seas, a storage device with a larger capacity can be made because of the support of the water body. However, since the soft plastic bag is exposed to the outside, the storage device has problems such as poor safety and reliability.

[0005] In summary, among the existing fluid material storage methods and devices, the tank storage devices using steel rigid structures have problems such as complex structure, high cost, easy corrosion, poor safety, and high maintenance costs; the storage devices using non-rigid flexible structures have problems such as poor safety and poor reliability. Summary of the invention

[0006] In view of the deficiencies in the prior art, an embodiment of the present invention aims to provide an inverted hood-type hydraulically-loaded material storage device, which uses a material storage and transportation device combining a rigid structure and a flexible structure to solve the problems existing in the existing material storage and transportation methods and devices.

[0007] In order to achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0008] An inverted hood type hydraulically loaded material storage device comprises: a shield and a material bag; the shield is a rigid shield, comprising a shield body, the shield body is placed below the liquid surface of a liquid medium, the shield body has an inner chamber, a channel is provided at the bottom of the side wall of the shield body, the channel connects the inner chamber with the outside of the shield body; the material bag is a flexible material bag, material is stored in the material bag, the density of the liquid medium is greater than the density of the material, and the material bag is placed on the top of the inner chamber of the shield.

[0009] Optionally, it also includes a liquid level control device and a pressure measuring device, wherein the liquid level control device is arranged in the liquid medium outside the shield, and the pressure measuring device includes a first pressure measuring device and a second pressure measuring device, wherein the first pressure measuring device is arranged in the inner chamber of the shield, and the second pressure measuring device is arranged in the material bag.

[0010] Optionally, the liquid level control device is a pump group, or a structure capable of adjusting the buoyancy.

[0011] Optionally, the liquid medium is medium water, and the medium water is an artificial water body or a natural water body.

[0012] Optionally, the inner wall of the shield is provided with a shield coating for protecting the material bag, and the shield coating is made of a flexible material.

[0013] Optionally, the shield further includes a shield platform, which is disposed on the shield body and is located on the liquid surface of the liquid medium.

[0014] Optionally, the liquid medium is placed in a reservoir, the bottom of the cover body of the protective cover is fixed to the bottom of the reservoir, and the reservoir is built on a foundation.

[0015] Optionally, the material of the shield is a metal material, an organic polymer material or a composite material; the material of the material bag is made of an organic polymer film material with fiber added.

[0016] Optionally, the shield is placed in a natural water source, and a fixing anchor for fixing the shield is provided at the bottom of the shield.

[0017] An embodiment of the present invention also provides a method for storing materials using the inverted cover type hydraulic bearing material storage device as described above: using a material bag to store and isolate the material, placing the material bag in a protective cover filled with a liquid medium to ensure that the pressure inside and outside the material bag is equal.

[0018] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0019] 1. The material storage device of the present invention uses a material bag made of a flexible material to achieve isolation and storage of materials, and places the material bag in a rigid liquid-filled shield so that both the inside and outside of the material bag are subjected to approximately equal liquid pressure. By placing the soft material bag in a rigid liquid-filled shield so that both the inside and outside of the material bag are subjected to approximately equal liquid pressure, the problems of insufficient rigidity strength, excessive deformation, and low single capacity of the soft material bag structure are solved. The rigid sleeve (i.e., shield) is a rigid shell structure with a certain rigidity strength, which can not only protect the material bag inside it, but also limit the deformation and movement of the material bag, and play a role in fixing the material bag. There are fluid channels and spaces around the material bag and the rigid shield. When the material bag is damaged and material leaks, the leaked material floats because its density is lower than that of the liquid medium, and is stored above the liquid surface inside the shield, isolated from the air, and can ensure safety. The material temporarily stored above the liquid surface inside the shield due to leakage can be recycled, and environmental protection performance can be ensured.

[0020] 2. To replace the traditional dome-type steel storage tank and floating roof steel storage tank, a composite device consisting of a built-in material bag and a rigid shield is placed in the water body. The lower opening of the shield is connected to the external water body. The pressure inside and outside the shield is equal. The shield structure has a small pressure. A light and thin structure can be used, or a polymer material with good corrosion resistance can be selected. The structure is simple and the cost is low.

[0021] 3. It avoids the problem of tank damage and foundation collapse caused by inconsistent deformation of the tank body and the foundation. It has high safety and can meet the dynamic load characteristics caused by material changes and temperature changes.

[0022] 4. The rigid-flexible composite shield composed of flexible material bags and rigid shields can be placed in natural water bodies such as rivers, lakes and seas, or can be specially made into artificial water bodies. When the rigid-flexible composite structure is placed in the water body, the material load is transferred to the dam foundation through the water body. The dam foundation can be built with materials such as concrete, avoiding the corrosion problems caused by the use of steel materials, the high cost of anti-corrosion structures, and the high maintenance and operation costs.

[0023] 5. The rigid-flexible composite structure can also be placed directly in natural water bodies such as rivers, lakes and seas. It can be towed or anchored in natural water bodies as needed, and can be used for storage and towing transportation in shallow seas and rivers. It has flexible and maneuverable characteristics and confidential transportation functions, and can be used for military transportation and storage.

[0024] 6. The present invention solves the contradiction between isolation function and bearing function by transferring the load of stored materials to water through material bags, water to the outer cabin, and the outer cabin to the foundation. The outer cabin can be constructed with concrete, with water on one side and the foundation on the other side, which can reduce the cost and be corrosion-resistant.

[0034] Example 1

[0035] In order to solve the technical problems raised in the background technology, the present invention proposes an inverted hood-type hydraulically-supported material 4 storage device, specifically a fluid material 4 storage device composed of a flexible variable-volume inner bag device that is hydraulically supported, water-sealed and isolated, and enclosed by a protective hood 12-type device. The device can be suitable for flammable, explosive and toxic chemicals such as alcohol, ether, hydrocarbon ester and acid, and belongs to chemical engineering.

[0036] The flexible material bag 10 is used to store and isolate the material 4. The material bag 10 is placed in a rigid shield 12 filled with liquid. The rigid material bag 10 provides protection for the material 4 and limits its deformation and movement. The force on the material bag 10 from the material 4 is balanced by adjusting the height of the liquid level in the shield 12. At the same time, the shield 12 can also provide isolation and collection when the material 4 leaks. The shield 12 can be placed in artificial water bodies or natural water bodies such as rivers, lakes and seas. When used in natural water bodies, it can be dragged or anchored as needed. It is flexible and efficient. It can be used for storage and transportation in shallow seas and rivers, and can also be used for towing. Due to its flexible and maneuverable characteristics, it can be used for military transportation storage and convenient confidential transportation. The device can solve the problems of complex structure, high cost, easy corrosion, poor safety, high maintenance cost, and excessive energy consumption in existing storage and transportation methods and devices.

[0037] like Figure 1As shown, in one embodiment of the present invention, an inverted cover type hydraulic bearing material 4 storage device is proposed, comprising: a shield 12 and a material bag 10; the shield 12 is a rigid shield 12, the shield 12 comprises a shield body, the shield body is placed below the liquid surface of the liquid medium, the shield body has an inner chamber 3, the bottom of the side wall of the shield body is provided with a channel 8, the channel 8 connects the inner chamber 3 with the outside of the shield body; the material bag 10 is a flexible material bag 10, the material 4 is stored in the material bag 10, the density of the liquid medium is greater than the density of the material 4, and the material bag 10 is placed on the top of the inner chamber 3 of the shield 12. The material bag 10 is placed in the shield 12, and the upper remaining space between the shield 12 and the material bag 10 is the inner chamber 3. The material bag 10 is attached with a material inlet and outlet and valve control system 11 for controlling the inlet and outlet of the material 4. The liquid medium is medium water 13, and the medium water 13 can be an artificial water body or a natural water body.

[0038] The material 4 storage device of the present invention uses a material bag 10 made of a flexible material to isolate and store the material 4, and places the material bag 10 in a rigid liquid-filled shield 12, so that both the inner and outer sides of the material bag 10 are subjected to approximately equal liquid pressure, thereby solving the problems of insufficient structural rigidity, excessive deformation, and low single-unit capacity of the soft material bag 10. The rigid housing (i.e., shield 12) is a rigid shell structure with a certain rigidity strength, which can protect the material bag 10 inside it, and limit the deformation and movement of the material bag 10, thereby playing the role of fixing the material bag 10.

[0039] When the material bag 10 is damaged and the material 4 leaks, the leaked material 4 floats up because of its lower density than the liquid medium and is stored above the liquid surface inside the shield 12, isolated from the air, and can ensure safety. The material 4 temporarily stored above the liquid surface inside the shield 12 due to leakage can be recycled, and environmental protection performance can be ensured.

[0040] The flexible material bag 10 is surrounded and protected by the rigid shield 12 and the shield coating 5 through the liquid medium in the inner chamber 3, ensuring that the material bag 10 is not easily damaged by impact, thereby solving the problem of low rigidity and poor safety of the flexible material bag 10.

[0041] The present invention combines the flexible material bag 10 with the rigid shield 12, which not only takes advantage of the good isolation function of the flexible material bag 10, but also overcomes the problem of low rigidity and poor safety of the flexible material bag 10. Because of the buffering effect of the liquid medium and the collection and isolation function of the leaked material 4 in the inner chamber 3 of the shield 12, the safety and environmental protection performance of the storage device of the present invention are higher than those of the existing storage devices.

[0042] Specifically, Figure 1As shown, a reservoir 2 is built on the foundation 1 for storing medium water 13, a shield 12 is installed in the reservoir 2, and a channel 8 is provided below the shield 12 to communicate with the reservoir 2. The medium water 13 can flow back and forth inside and outside the shield 12 through the channel 8, so that the pressure inside and outside the shield 12 is basically equal.

[0043] The function of the medium water 13 is to transfer the load and isolate the material 4 from the outside air. The medium water 13 can be natural river, lake, sea water, etc., preferably tap water. In some special occasions, the medium water 13 can be sterilized, disinfected, anticorrosive, and antifreeze.

[0044] The storage capacity of the reservoir 2 should be sufficient. When the material 4 is completely filled, the water level of the medium water 13 reaches the highest without overflowing. When the material 4 in the material bag 10 is completely discharged, the inner chamber 3 should be full of water. The reservoir 2 can have a top cover to prevent dust and evaporation. Usually, the water surface of the reservoir 2 is connected to the atmosphere. In special occasions, the reservoir 2 can adopt a closed structure, combined with a breathing valve, to further reduce water evaporation.

[0045] During feeding, the amount of material 4 in the material bag 10 increases, and the internal pressure of the material bag 10 increases. The liquid level control device 6 adjusts the liquid level so that the external force and internal force of the medium water 13 on the material bag 10 are equal. The medium water 13 provides external pressure to the material bag 10, and the load of the material 4 is transferred to the medium water 13 through the material bag 10, and then to the foundation 1 through the medium water 13. Compared with the load transfer mode of the existing steel tank storage tank, the load is transferred evenly by using water as the load. Even if the foundation 1 is uneven and deformed, it basically does not affect the uniform transfer of the load. As long as the water reservoir 2 is well sealed, the water volume is sufficient, and the water level is high enough, the load transfer function of the storage device is intact.

[0046] The foundation 1 can be in various forms, such as above-ground, semi-buried, buried, etc. When building a large storage base, the natural geographical advantages of rivers, lakes and seas can also be used to reduce construction costs. The reservoir 2 can be a concrete structure or other materials. Multiple reservoirs 2 can be placed in one foundation 1, and multiple shields 12 can also be placed in one reservoir 2. Multiple material bags 10 can be placed in one set of shields 12.

[0047] The material 4 leaked from the material bag 10 floats at the highest point of the inner chamber 3 because its density is lower than that of water, thus avoiding leakage above the water surface and contact with the air, thereby improving the safety of the material 4 storage device, collecting the leaked material 4 in the inner chamber 3, ensuring the environmental performance of the storage device, and improving the safety and environmental performance of the system.

[0048] The liquid pressure in the material bag 10 is nearly equal, the tensile stress is low, and the capacity of the material bag 10 can be very large, which solves the problem of small storage capacity of existing oil bags and meets the needs of large, medium and small storage capacities. Due to the change in the stress state, the requirements for the rigidity and strength of the material of the material bag 10 are greatly reduced, solving the safety problem of the flexible material bag 10.

[0049] The material of the material bag 10 can be made of a fiber-added organic polymer film material, preferably a glass fiber cloth coated with polytetrafluoroethylene. The material of the shield 12 is a metal material or an organic polymer material and a composite material. The bottom of the shield 12 is fixed to the bottom of the reservoir 2, the pressures on both sides of the inner chamber 3 are similar, and the load is small. The shield 12 can be made of a thin-walled polymer material, which is low in cost, light and corrosion-resistant.

[0050] There may also be a truss-type connector in the medium water 13 to connect the reservoir 2 and the shield 12, so that the two are interconnected through a truss-type structure to optimize the overall force-bearing structure of the storage device and increase its rigidity and strength.

[0051] The inverted cover type hydraulic bearing material 4 storage device also includes a liquid level control device 6 and a pressure measuring device. The liquid level control device 6 is arranged in the liquid medium outside the shield 12. The pressure measuring device includes a first pressure measuring device 9 and a second pressure measuring device 7. The first pressure measuring device 9 is arranged in the inner chamber 3 of the shield 12, and the second pressure measuring device 7 is arranged in the material bag 10. The liquid level is adjusted by the liquid level control device 6 to control the external pressure on the material bag 10 to ensure that it is equal to the internal pressure. Pressure measuring devices are respectively arranged in the material bag 10 and the shield 12 to detect the internal and external pressures of the material bag 10 in real time, and the liquid level is adjusted according to the change of pressure to ensure that the internal and external pressures of the material bag 10 are equal. When the shield 12 is placed in an artificial water body filled with liquid made of foundation 1 and concrete, the liquid level control device 6 can use a pump group.

[0052] Furthermore, the inner wall of the shield 12 is provided with a shield coating 5 for protecting the material bag 10, and the shield coating 5 is made of a flexible material. The shield coating 5 made of the same material as the material bag 10 or other soft materials is provided inside the shield 12 to protect the material bag 10.

[0053] The shield 12 also includes a shield platform 14, which is arranged on the shield body and is located on the liquid surface of the liquid medium. By arranging the shield platform 14 on the upper part of the shield 12, it can not only protect the internal liquid from evaporation and prevent the entry of external liquid and impurities, but also place the control system and other equipment on the platform and perform maintenance operations. The shield 12 is convenient for fixing the relevant position of the material bag 10 and limiting its movement. The top shield platform 14 is convenient for access operation and prevention of the control system.

[0054] Example 2

[0055] The difference between this embodiment and embodiment 1 is that the storage device is arranged at a different location. Figure 2 As shown, the device in this embodiment is to place the material bag 10 and the protective cover 12 in a natural water source 2-1 such as a river, lake or sea, and to attach a fixing anchor 15 to the bottom of the protective cover 12 for fixing the protective cover 12. The use principle of this embodiment is the same as that of the embodiment 1, which is different from the ground fixed storage in the embodiment 1. This embodiment can be used for storage in shallow seas and rivers, and can also be used for hauling. It can be hauled or fixed with an anchor as needed, and is used for storage and hauling transportation in the ocean and rivers. It has flexible and maneuverable characteristics and confidential transportation functions, and can be used for military transportation and storage.

[0056] When the protective cover 12 is placed in the natural water source 2 - 1 , the liquid level control device 6 can use a bag or other device with adjustable buoyancy, and the liquid level control device 6 is arranged at the bottom of the protective cover 12 .

[0057] In summary, the present invention finds through analysis and research on the storage function and process of fluid materials that the storage function can be divided into an isolation function and a carrying function.

[0058] Existing steel storage tanks are composed of steel tank bodies and other parts to complete the isolation and load-bearing functions of the storage device. Steel tanks made of steel materials have high rigidity, strong load-bearing capacity, and strong ability to maintain shape. Among them, the dome-type steel storage tank has a fixed volume, but there are problems such as large material breathing loss and poor isolation performance. Floating roof steel storage tanks use a mobile floating roof to change the storage volume to meet the needs of volume changes during material storage, improve the isolation function, and can significantly reduce breathing losses. The problem is that it requires a complex floating roof device with a complex overall structure, high cost, high failure rate, and high maintenance costs.

[0059] Existing steel storage tanks have poor corrosion resistance to material media and external environmental media such as water and soil. On the one hand, the corrosion resistance is improved by coating with anti-corrosion coatings, and on the other hand, the tank body is installed above ground to keep it away from corrosive media such as wet soil. When the above-ground installation method is used, the load of the material is borne by the tank body. As the storage capacity increases, the stress of the tank body increases, and it is necessary to use better quality steel and increase the wall thickness.

[0060] Because the fluid has a tendency to flow downward under the influence of gravity, the fluid material storage device needs to have the function of bearing the gravity load of the fluid material. As the amount of stored fluid material increases, the height and lateral dimensions of the storage tank increase, the load of the fluid material increases, and the stress of the storage container shell increases. Existing large storage tanks need to be made of high-strength steel, the thickness of the steel plate increases, and the material cost increases. The material gravity load is transmitted to the foundation through the bottom of the tank. When the material inventory in the storage tank is different, the vertical load is different, the deformation of the tank bottom is different, the load on the ground is also different, and the deformation of the ground changes. The tank body and the foundation are made of different materials, have different thermal expansion coefficients, and have different structures. When the material inventory and temperature change repeatedly, the deformation between the bottom of the tank body and the foundation cannot be kept consistent, which will generate additional stress and have an adverse effect on the safety of the tank and the foundation. In actual application, there are problems such as damage to the bottom plate of the tank and collapse and tilt of the foundation. Therefore, the design concept of the tank body and foundation based on the rigid structure cannot adapt to the dynamic load characteristics of the storage device and cannot fully realize the bearing function of the storage device.

[0061] As a material storage device, repeated cyclic changes in material inventory and temperature are inevitable. The present invention transfers loads in a hydraulic manner to better adapt to repeated changes in loads caused by repeated cyclic changes in material inventory and temperature. Water can transfer loads evenly, and water bodies can deform to adapt to changes in loads. Water is amorphous and can be deformed arbitrarily without breaking.

[0062] The existing oil bag storage device relies on a soft oil bag structure to achieve the isolation function and load-bearing function of the storage device. The material can be in close contact with the inner surface of the material bag and completely isolated from the outside world, with a perfect isolation function, a shapeless storage volume, and a variable capacity. The present invention improves the material storage device so that during its storage and transportation, it can avoid contact with metals and their compounds and air as much as possible. All materials in contact with the material, including the material bag and the inner cabin, are made of non-metallic materials with stable physical and chemical properties, such as polytetrafluoroethylene materials, polypropylene, etc.

[0063] The storage device must first have a storage space so that the material can be isolated from the environment, preferably completely isolated from the air, and also isolated from the air when the material enters and leaves the storage space. This problem can be solved by using a foldable, elastically deformable bag-type container made of flexible materials. When the material bag is filled with fluid material, the material bag can expand and the volume increases. During the deformation process, the inner wall of the material bag remains in contact with the fluid. When the fluid material is discharged from the material bag, the material bag can shrink and the volume decreases. During the deformation process, the inner wall of the material bag remains in contact with the fluid, thereby isolating the fluid material from environmental media such as air.

[0064] The material bag can also be isolated from the outside world by being wrapped in an inert medium. The inert medium for light hydrocarbon materials includes water, nitrogen, etc. Water has the advantage of being cheap and easy to obtain, so it is the first choice as an inert medium.

[0065] Soft material bags are easy to deform and have good isolation effects, but they have low structural rigidity, poor safety and reliability, and low monomer capacity. Material bags made of flexible materials need to change their structure and load-bearing methods to increase storage capacity and improve safety.

[0066] In order to avoid excessive deformation, the present invention adopts the method of placing a soft material bag in a rigid liquid-filled protective cover so that the inner and outer sides of the material bag are subjected to approximately equal liquid pressure, thereby changing the force-bearing mode of the material bag and greatly reducing the tensile stress borne by the material of the material bag. This can solve the problems of insufficient structural rigidity and strength of the soft material bag, excessive deformation, and low single-body capacity.

[0067] The rigid shield is a rigid shell structure with a certain rigidity strength, which can protect the material bag inside it and improve the safety and reliability of the material bag. The rigid shell structure can limit the deformation and movement of the material bag, further improving the safety of the storage device.

[0068] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
