Technical Field
[0001] This utility model relates to the field of gas storage technology, and more specifically, to a carbon dioxide spherical gas storage tower. Background Technology
[0002] Carbon dioxide is a greenhouse gas, found in large quantities in the exhaust gases of the coal chemical industry, and its direct emission contributes to the greenhouse effect. Carbon dioxide has a wide range of applications. In industry, it is used as a welding shielding gas, a metalworking aid, a chemical raw material, and in water treatment; in the food and beverage industry, it is used as an additive in carbonated beverages, for preservation, storage, and processing; in agriculture, it can be used as a fertilizer and for grain storage; in the medical field, it acts as a respiratory stimulant and is used in medical equipment; in the environmental field, it is used as an aerosol propellant, contributing to greenhouse gas emission reduction; furthermore, it has wide applications in fire protection, the electronics industry, and scientific research.
[0003] Carbon dioxide is recovered from waste gas generated during the production process of the coal chemical industry. The industrial waste gas undergoes pretreatment, compression, fine treatment, and liquefaction to remove impurities and harmful substances, yielding high-purity carbon dioxide. This process effectively utilizes industrial waste gas and reduces greenhouse gas emissions. After production, the carbon dioxide is stored under high pressure. Due to its unique spherical structure, spherical storage towers offer advantages such as uniform stress distribution, high space utilization, and good stability, and are increasingly being used for carbon dioxide storage. Existing spherical storage towers typically use skirt supports or column supports for spherical support, resulting in relatively simple structures but poor seismic performance. Utility Model Content

[0032] Reference Figures 1 to 4As shown, this utility model discloses a spherical carbon dioxide gas storage tower, which includes a spherical tank 100, a support frame 200, and a shock-absorbing assembly 300. The support frame 200 has n columns 210, the upper ends of which are connected to the spherical tank 100; where n ≥ 3. The shock-absorbing assembly 300 includes shock-absorbing rods 310, shock-absorbing bases 320, and shock absorbers 330. The upper ends of the shock-absorbing rods 310 are fixedly connected to the columns 210, and the lower ends are inserted into the shock-absorbing bases 320. One end of the shock absorber 330 is rotatably connected to the outer peripheral wall of the shock-absorbing rod 310, and the other end is rotatably connected to the shock-absorbing bases 320. Specifically, in this embodiment, the support frame 200 adopts a design with multiple columns 210. This parametric design allows the structure of the storage tower to be adjusted according to actual needs. For carbon dioxide storage projects of different scales and storage requirements, the load-bearing capacity and stability of the support frame 200 can be flexibly adjusted by changing parameters such as the number, size, and layout of the columns 210 to adapt to various engineering conditions, thus improving the versatility and applicability of the structure. Under normal conditions, the n columns 210 of the support frame 200 bear the weight of the spherical tank 100 and the carbon dioxide stored inside. The multiple columns 210 are evenly distributed, distributing the gravity to the concrete foundation below, ensuring that the spherical tank 100 is in a stable supported state and maintaining the static balance of the storage tower. When the storage tower is subjected to vibration, such as earthquakes or vibrations caused by nearby large machinery operations, the shock absorbers 330 connecting the outer wall of the shock absorber rod 310 and the shock absorber base 320 begin to function. Since both ends of the shock absorber 330 are rotatably connected, it can flexibly rotate and extend with the movement of the shock absorber rod 310. The shock absorber 330 deforms and rubs during this process, converting the mechanical energy of the vibration into heat and other forms of energy, thereby reducing the vibration amplitude transmitted to the shock absorber base 320 and the entire storage tower structure, protecting the spherical tank 100 and other structural components from damage caused by excessive vibration. The shock absorber assembly 300 not only copes with earthquakes but also buffers various minor vibrations and impacts during daily operation, reducing repeated damage to the spherical tank 100 and support frame 200, extending the overall service life of the equipment, reducing long-term maintenance costs and equipment replacement frequency, and improving economic efficiency. Thanks to the excellent shock absorption performance of the shock absorber assembly 300, the design structure in this embodiment is highly adaptable to different geological conditions. Whether in areas with frequent seismic activity or complex geological conditions, the shock absorber assembly 300 can ensure safe and stable operation, expanding the site selection range of this device and increasing the flexibility of project construction.
[0033] In this embodiment, the spherical tank 100 may optionally be equipped with an inlet and an outlet for the entry and exit of carbon dioxide gas, typically fitted with corresponding valves to control the gas flow rate and pressure. A safety valve automatically releases pressure when the pressure inside the spherical tank 100 exceeds a set value to prevent accidents such as explosions due to overpressure. A pressure gauge monitors the pressure inside the spherical tank 100 so that operators can promptly understand the pressure situation and take appropriate measures. A thermometer measures the temperature inside the spherical tank 100, as the storage state of carbon dioxide is closely related to temperature; monitoring the temperature ensures that the carbon dioxide is stored under suitable conditions. A level gauge measures the liquid level in the spherical tank 100 for storing liquid carbon dioxide, thus controlling the amount of material entering and leaving the tank.
[0034] In some embodiments of this utility model, the support frame 200 includes a scissor brace 220, which includes two tie rods 221 arranged in a scissor-like configuration between two adjacent columns 210 of the spherical tank 100. Specifically, in this embodiment, when facing horizontal forces such as wind loads, the scissor brace 220 can improve the lateral force resistance of the support frame 200. The wind's action on the spherical tank 100 causes the columns 210 to bear horizontal thrust, while the scissor brace 220, through the force transmission of the tie rods 221, distributes the horizontal force to more columns 210, reducing the horizontal load borne by a single column 210, lowering the risk of instability due to excessive horizontal force, and ensuring the stability of the entire storage tower in strong winds. During an earthquake, ground movement causes complex vibrations in this device. The presence of the scissor brace 220 can change the dynamic characteristics of the support frame 200, increasing the structural stiffness and damping. Under seismic action, the scissor-type tie rod 221 will generate an alternating tension and compression stress state. Through its own deformation and energy dissipation, it absorbs the energy input by the earthquake, reduces the vibration response of the storage tower, improves the safety and reliability of the spherical tank 100 in the earthquake, and effectively protects the spherical tank 100 and the carbon dioxide stored inside.
[0035] In some embodiments of this utility model, the scissor brace 220 includes a connecting plate 222, which is disposed at the intersection of the two tie rods 221. Specifically, in this embodiment, the intersecting tie rods 221 form a relatively stable geometric shape under the action of the connecting plate 222. The connecting plate 222 restricts the relative displacement of the tie rods 221 at the intersection point, preventing the tie rods 221 from shifting or separating during the stress process, thus maintaining the scissor-like structural form of the scissor brace 220. This stable structural shape helps to better exert the supporting and constraining effect of the scissor brace 220 on the adjacent columns 210, ensuring that the entire support frame 200 maintains good mechanical performance under various working conditions.
[0036] In some embodiments of this utility model, the support frame 200 further includes a connecting ring 230, which is sleeved on the spherical tank 100, and the upper end of the column 210 is connected to the connecting ring 230. Specifically, in this embodiment, the connecting ring 230 connects the upper ends of all the columns 210 together, forming a closed ring structure around the spherical tank 100. This structure enhances the integrity of the entire support frame 200, enabling the columns 210 to work together. When subjected to external horizontal forces, such as wind or seismic forces, the connecting ring 230 can transfer the force on one side of the column 210 to the other side, allowing the entire support frame 200 to resist external forces as a whole, reducing the possibility of excessive stress on a single column 210, and improving the structure's lateral force resistance and overall stability.
[0037] In some embodiments of this utility model, a positioning post 332 is provided on the shock-absorbing base 320, and a slot 333 is provided on the positioning post 332. A pin 311 is provided at the lower end of the shock-absorbing rod 310 corresponding to the slot 333. Specifically, in this embodiment, during installation, the pin 311 at the lower end of the shock-absorbing rod 310 is aligned with and inserted into the slot 333 on the positioning post 332. This quickly and accurately determines the position of the shock-absorbing rod 310 on the shock-absorbing base 320, achieving a reliable connection between the shock-absorbing rod 310 and the shock-absorbing base 320. After the pin 311 is inserted into the slot 333, a rigid connection is formed between the shock-absorbing rod 310 and the shock-absorbing base 320. When the shock-absorbing assembly 300 is working, whether during normal vibration buffering or under a large external impact, the shock-absorbing rod 310 can effectively transmit the force it bears to the shock-absorbing base 320 through the cooperation of the pin 311 and the slot 333. Meanwhile, this connection method restricts the displacement and rotation of the damping rod 310 on the damping base 320, enhancing the structural stability of the entire damping assembly 300 and improving the damping effect. For example, when an earthquake occurs, the damping rod 310 can better cooperate with components such as the damper 330 to resist seismic forces and reduce the impact of vibration on the superstructure.
[0038] In some embodiments of this utility model, the pin 311 is a non-rotating structure. Specifically, in this embodiment, the shape of the non-rotating pin 311 provides guidance for installation. During installation, the installer only needs to insert the pin 311 into the slot 333 according to its shape, without the need for additional markings or complicated operating steps. This simple and intuitive installation method not only improves installation efficiency but also reduces rework costs caused by installation errors. In addition, the design of this structure restricts the displacement and rotation of the damping rod 310 on the damping base 320, enhancing the structural stability of the entire damping assembly 300 and improving the damping effect.
[0039] In some embodiments of this utility model, the pin 311 is a polygonal prism structure. Specifically, in this embodiment, the pin 311 is a quadrangular prism structure. This design restricts the displacement and rotation of the damping rod 310 on the damping base 320, enhances the structural stability of the entire damping assembly 300, and improves the damping effect.
[0040] In some embodiments of this utility model, the cross-sectional diameter of the column 210 is D1, the cross-sectional diameter of the shock absorber 310 is D2, and the cross-sectional diameter of the positioning column 332 is D3, wherein D1 < D2 < D3. Specifically, in this embodiment, the design of the variable radius structure can form a gradual stiffness distribution according to the function and stress requirements of different components. The larger diameter of the positioning column 332 gives it higher stiffness, which can effectively resist the overall deformation of the structure.
[0041] In some embodiments of this utility model, damping rubber sleeves 331 are respectively provided at both ends of the shock absorber 330. Specifically, in this embodiment, the presence of damping rubber sleeves 331 increases the energy dissipation capability of the shock absorber 330 system. During vibration, the elastic deformation and viscous damping effect of the rubber sleeves can continuously consume vibration energy, enabling the shock absorber 330 to reduce the vibration amplitude more quickly and effectively.
[0042] In some embodiments of this utility model, the shock-absorbing base 320 is provided with anchor bolt holes 321. Specifically, in this embodiment, the shock-absorbing base 320 and the anchor bolts pre-embedded in the concrete foundation can be fixedly connected through the anchor bolt holes 321, thereby improving the seismic performance of this device.
[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
