Description

Technical Field

[0001] This utility model relates to the field of gas storage equipment technology, specifically a 150,000 cubic meter wet vertical gas storage tank. Background Technology

[0002] The invention of wet gas holders can be traced back to the early 19th century. In 1819, British engineer Samuel Clegg built the world's first documented wet gas holder on Westminster Bridge Road in London to store coal gas and provide fuel for street lighting. This technology emerged with the popularization of city gas (coal-to-gas), solving the key problem of the mismatch between gas production and consumption in time (i.e., "peak shaving"), and was a milestone in the history of urban utility development.

[0003] Before the advent of wet gas storage tanks, large-scale storage of natural gas was impossible. Their invention and development primarily aimed to solve the following core problems: 1. Supply and demand balance (peak shaving): Gas production (such as coal distillation) is a continuous process, but urban gas consumption (nighttime lighting, daytime cooking) fluctuates. Gas storage tanks can store gas during off-peak hours and release it during peak hours, effectively balancing pipeline pressure.

[0004] 2. Stabilize pipeline pressure: The gas storage tank relies on the weight of the bell and tower sections to output gas, and its pressure is very stable, providing a reliable "pressure stabilizer" for the early and fragile urban gas pipeline network.

[0005] 3. Safe storage: It provides a well-sealed, safe and reliable method for storing flammable and explosive gases, which is a huge technological advancement compared to earlier gasbags or gas bladders.

[0006] However, existing wet gas storage tanks still have the following technical shortcomings: Insufficient guidance stability: Traditional gas storage tanks may mainly rely on a single internal or external guidance system. When there is wind load or uneven lifting of tower sections, the tower body is prone to tilting or jamming, affecting operational safety and lifespan.

[0007] Liquid seal performance and pressure balance: The design of the water seal structure between tower sections directly affects the sealing reliability and the resistance to tower section lifting and lowering. An unreasonable liquid seal design may lead to sloshing of the sealing fluid, large evaporation losses, or internal and external pressure imbalance, affecting the smoothness of lifting and lowering.

[0008] Structural complexity and maintenance costs: Simplifying the structure and improving the maintainability and durability of each component (especially guide wheels and guide rails) are key to reducing the total life-cycle cost of large gas storage tanks.

[0009] In summary, how to solve the above-mentioned defects has become a technical problem that urgently needs to be solved by those in this field. Utility Model Content

[0010] This utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this utility model is to propose a 150,000 cubic meter wet vertical gas storage tank, aiming to solve the technical problems of insufficient guiding stability, poor liquid sealing effect leading to operational jamming, and inconvenient structural maintenance of existing large wet gas storage tanks.

[0011] To address the aforementioned problems, this utility model provides a 150,000 cubic meter wet vertical gas storage tank, comprising a water tank, an annular tower section, and an external truss. The water tank is fixed to the bottom surface, and the external truss is fixed to the ground outside the water tank in a ring arrangement. The water tank is filled with sealing liquid and consists of multiple levels of annular tower sections coaxially nested together. Each level of the annular tower section has an upper hanging ring fixed to its top circumferentially, and a lower hanging ring fixed to its bottom circumferentially, which cooperates with the upper hanging ring for liquid sealing. The top of the uppermost annular tower section is sealed with a bell jar. The upper hanging ring is connected to the external truss in a lifting and rolling manner, and the lower hanging ring is connected to the inner wall of the next lower level of the annular tower section in a lifting and rolling manner.

[0012] Preferably, the upper hanging ring includes an upper sealing ring, an upper guide wheel bracket, an upper guide wheel, and a liquid distribution ring. The upper sealing ring is sealed and fixedly connected to the top surface of each annular tower section. The top surface of the upper sealing ring fixes multiple upper guide wheel brackets, which radially support the upper guide wheel. The upper guide wheel is then connected to the external truss by moving up and down and rolling against it. The liquid distribution ring is fixedly connected to the inner ring of the upper sealing ring.

[0013] Preferably, the liquid separating ring is inserted into the lower hanging ring to separate the sealing liquid in the lower hanging ring into an inner ring liquid surface and an outer ring liquid surface that are connected. The inner ring liquid surface is connected to the pressurized gas storage inside the annular tower section, and the outer ring liquid surface is connected to the external atmosphere of the annular tower section.

[0014] Preferably, the lower hanging ring includes a lower water storage ring groove and a lower guide wheel; the lower water storage ring groove is fixed on the circumferential outer wall of the bottom of the annular tower section, the top of the lower water storage ring groove is open and the inside is filled with sealing liquid, and the bottom of the lower water storage ring groove protrudes radially and is rotatably connected to the lower guide wheel.

[0015] Preferably, guide rails are vertically fixed on the inner wall and the outer truss of the annular tower section, wherein the lower guide wheel of the guide rail on the inner wall of the annular tower section is supported by a lifting guide, and the upper guide wheel of the guide rail on the outer truss is supported by a lifting guide.

[0016] Preferably, the height of the water tank and the depth of the water inside are both greater than the vertical height of the multi-stage annular tower section.

[0017] The advantages of this utility model compared with the prior art are as follows: 1. Dual guidance for extremely stable operation: An external guidance system is formed by the "upper guide wheel + external truss guide rail," while an internal guidance system is formed by the "lower guide wheel + lower stage tower plate inner wall guide rail," creating a three-dimensional guidance system combining internal and external components. This design greatly enhances the anti-overturning ability and stability during the tower section lifting process, ensuring that towers weighing tens of thousands of tons can be lifted and lowered vertically and smoothly, making it particularly suitable for large gas storage tanks of tens of thousands of cubic meters.

[0018] 2. Optimized Liquid Seal, Controllable Pressure: The innovative "liquid separation ring" design is the core. It separates the sealing liquid in the lower hanging ring (lower water storage ring groove) into an "inner ring liquid surface" (connected to the inside of the gas holder, bearing gas pressure) and an "outer ring liquid surface" (connected to the atmosphere). This separation ensures that the pressure acting on the liquid seal mainly comes from the gas storage pressure, forming a controllable pressure difference with the external atmospheric pressure. This guarantees the absolute reliability of the seal and reduces the resistance caused by liquid surface fluctuations during tower section lifting, making operation smoother.

[0019] 3. Modular design for easy maintenance: The upper and lower hanging rings have clear structures and well-defined functions. The guide wheels, being vulnerable components, are easily inspected and replaced via a curved arm support. The water tank depth exceeds the total height of the tower section, ensuring sufficient sealing fluid even in the worst-case scenario (e.g., if all tower sections fall), guaranteeing high safety.

[0025] This utility model discloses a 150,000 cubic meter wet vertical gas storage tank, comprising a water tank 4, an annular tower section 2, and an external truss 3. The water tank is fixed on the bottom surface, and the external truss is fixed in a ring on the ground outside the water tank. The water tank is filled with sealing liquid and has multiple levels of annular tower sections coaxially nested and connected in sequence. Each level of the annular tower section has an upper hanging ring fixedly connected to the top circumferentially, and a lower hanging ring fixedly connected to the bottom circumferentially, which cooperates with the upper hanging ring to perform liquid sealing. The top of the uppermost level of the annular tower section is sealed with a bell jar 1. The upper hanging ring is connected to the external truss for lifting and rolling, and the lower hanging ring is connected to the inner wall of the next lower level of the annular tower section for lifting and rolling.

[0026] Preferably, the upper hanging ring includes an upper sealing ring 6, an upper guide wheel bracket 5, an upper guide wheel 7, and a liquid distribution ring 9. The upper sealing ring is sealed and fixedly connected to the top surface of each annular tower section. The top surface of the upper sealing ring fixes multiple upper guide wheel brackets, which radially support the upper guide wheels. The upper guide wheels are then connected to the external truss by moving up and down and rolling against each other. The liquid distribution ring is fixedly connected to the inner ring of the upper sealing ring.

[0027] Preferably, the liquid separating ring is inserted into the lower hanging ring to separate the sealing liquid in the lower hanging ring into an inner ring liquid surface and an outer ring liquid surface that are connected. The inner ring liquid surface is connected to the pressurized gas storage inside the annular tower section, and the outer ring liquid surface is connected to the external atmosphere of the annular tower section.

[0028] Preferably, the lower hanging ring includes a lower water storage ring groove 8 and a lower guide wheel 10; the lower water storage ring groove is fixed on the circumferential outer wall of the bottom of the annular tower section, the top of the lower water storage ring groove is open and the inside is filled with sealing liquid, and the bottom of the lower water storage ring groove protrudes radially and is rotatably connected to the lower guide wheel.

[0029] Preferably, guide rails are vertically fixed on the inner wall and the outer truss of the annular tower section, wherein the lower guide wheel of the guide rail on the inner wall of the annular tower section is supported by a lifting guide, and the upper guide wheel of the guide rail on the outer truss is supported by a lifting guide.

[0030] Preferably, the height of the water tank and the depth of the water inside are both greater than the vertical height of the multi-stage annular tower section.

[0031] To more clearly illustrate the specific implementation of this utility model, an embodiment is provided below: Combined with appendix Figure 2 and Figure 3 The working principle of this utility model is as follows: Initial state (gas storage capacity is zero or minimum): such as Figure 3 As shown, all annular tower sections 2 descend back into the annular water tank 4, and the water storage annular tank 8 of the lower hanging ring is submerged in water, forming an initial seal.

[0032] Gas filling process (increased gas storage): As the gas is introduced into the gas storage tank, the gas pressure gradually increases. The gas pressure first acts on the innermost annular tower section (and bell jar 1), overcoming its own weight and liquid seal resistance, and then pushes it to rise first. As gas is continuously injected, the pressure continues to increase, and each annular tower section rises sequentially from the inside out. During the rising process, the upper guide wheel 7 of each tower plate rolls vertically along the guide rail on the outer truss 3, providing external guidance; at the same time, the lower guide wheel 10 of the same tower plate rolls vertically along the guide rail on the inner wall of the next tower plate, providing internal guidance. This dual guidance mechanism ensures the verticality and stability of the tens of thousands of tons of tower body lifting and lowering. The liquid separating ring 9 is inserted below the liquid surface of the water storage ring trough 8 of the next tower plate as the tower plate rises, separating the sealing liquid and forming a dynamic and reliable pressure balance liquid seal.

[0033] Exhaust process (reduction of gas storage): As the external pipeline consumes the gas, the gas pressure inside the cabinet drops, and the trays gradually fall under their own weight, smoothly expelling the gas. The guide wheel system also ensures the stability of the sinking process. This continues until all trays have completely fallen back into water tank 4, restoring the initial state.

[0034] Throughout the entire working cycle, the "deep liquid level" design of tank 4 provides the ultimate safety guarantee for the system.

[0035] Finally, any aspects of this utility model not fully described herein utilize existing mature products and technologies.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
