System for storing high pressure gas on seabed and method thereof
InactiveCN103225737AImprove securityLow costContainer filling methodsPressure vesselsOcean bottomInternal pressure
The invention relates to a system for storing high pressure gas on the seabed and a method thereof. By the utilization of a gas compressor, a gas is continuously compressed through an air inlet pipe into an enclosed gas tank arranged on the seabed, thus realizing storage of the high pressure gas. When the high pressure gas in the enclosed gas tank needs to be used, the high pressure gas is released out of the enclosed gas tank through an exhaust pipe and used for energy conversion. The difference between internal pressure and external pressure, which are applied on a housing of the enclosed gas tank when the high pressure gas is stored in or discharged out of the enclosed gas tank, is within the range of pressure that the housing of the enclosed gas tank can bear. By the adoption of the gas storage system provided by the invention, resultant force applied on the enclosed gas tank can be effectively reduced. That is to say, more high pressure gases can be filled in the enclosed gas tank, and a thick tank wall is not required for supporting. Thus, the cost of the enclosed gas tank is lower, and the enclosed gas tank arranged on the seabed is safer.
