Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurized gas storage tanks experience significant pressure fluctuations during charging, discharging, and usage, affecting upstream and downstream users and complicating the operation of compressors/boosters.
Innovation Solution
A gas storage system with a pressure-stabilized tank and a pressure-stabilizing medium charging and discharging system that adjusts the tank's volume through automatic charging and discharging of a pressure-stabilizing medium, using either a liquid medium with a pressurizing pump or a low-boiling-point phase-changeable medium with an evaporation-condensation system to maintain constant pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pressurized gas storage tank is used, then the tank can store gas, but the pressure varies widely during charging, usage, and discharging
Solution Approach 1:
The patent applies the dynamics principle by making the liner volume adjustable rather than fixed. The liner can dynamically change its volume to compensate for pressure variations during charging and discharging operations, thereby maintaining stable pressure for downstream users while accommodating varying gas quantities.
Solution Approach 2:
The patent changes the parameter of liner volume to control pressure stability. By adjusting the liner volume in response to pressure changes during charging and discharging, the system maintains constant pressure output, resolving the contradiction between pressure stability and operational ease.
2Productivity
If pressure varies widely in the storage tank, then charging and discharging can proceed, but the difficulty of charging and compressor configuration increases
Solution Approach 1:
The patent introduces an intermediary mechanism (the adjustable liner) between the storage tank and the charging/discharging system. This liner acts as a buffer that absorbs pressure fluctuations, allowing charging and discharging to proceed smoothly while simplifying the requirements for compressors and downstream equipment.
3Reliability
If the storage tank volume is fixed, then the structure is simple, but the pressure cannot be maintained stable during charging and discharging
Solution Approach 1:
The patent transforms the fixed tank structure into a dynamic system where the liner volume can adjust. This dynamic adjustment capability enables pressure stabilization during charging and discharging while adding only the necessary components for volume adjustment, achieving a balance between reliability and structural complexity.

AI summary
A gas storage system capable of maintaining stable pressure in a pressurized storage tank, includes a pressure-stabilized gas storage tank and a pressure-stabilizing medium charging and discharging system connected to the pressure-stabilized gas storage tank. The pressure-stabilized gas storage tank includes a pressure-bearing shell capable of bearing a pressure of a storage gas, an elastic liner arranged in the pressure-bearing shell, and a support device for the elastic liner. A pressure-stabilizing medium may be a liquid medium, and a volume of the storage tank is adjusted by charging through pressurizing with a pump or by automatic discharging. The pressure-stabilizing medium may also be a low-boiling-point phase-changeable medium under an operating pressure, and evaporation-condensation of the pressure-stabilizing medium is automatically adjusted according to a variation in a volume of a stored gas by using a matched evaporation-condensation system.
