COMPRESSED GAS STORAGE SYSTEM

摘要

A pressurized gas storage system is disclosed for maintaining a minimum pressure of a primary fluid (5). The system includes a pressurized gas tank (2) inside which is mounted a flexible bladder (4) which contains the primary fluid. The space between the gas tank and the bladder is considered a compression chamber (9) which contains a secondary fluid (7) that exerts pressure on the bladder to maintain a minimum pressure upon the primary fluid. The secondary fluid is supplied to and exits tank pressure chamber through a port (6). The flexible bladder is couple to inlet outlet port (8) extending to a pickup tube (10). The system also includes a pump (18), fluid reservoir (14), pressure relief valve (24) and controller (26) which functions to maintain the pressure of the secondary fluid. In a second embodiment, pressure is maintained through a second fluid absorbing and releasing material.

主权项

1. A pressurized gas storage system comprising:
a pressure tank; an expandable bladder, the expandable bladder being mounted within said pressure tank and holding a secondary fluid; said expandable bladder creating a pressure chamber between said bladder and said pressure tank for holding a primary fluid; and a persistent pressure source, said persistent pressure source being coupled to the bladder and supplying and removing the secondary fluid therefrom while maintaining a prescribed pressure range thereof; whereby the supply and removal of the secondary fluid under persistent pressure to and from the expandable bladder causes the expandable bladder to expand and contract as primary fluid is removed from and supplied to the pressure chamber.
