Systems and methods for cascading burst discs

摘要

Systems and methods are provided herein for gas storage and the safe release of gas using cascading burst discs. A vessel for storing gas is in pneumatic communication with a first flow path. A first burst disc is disposed in the first flow path such that gas flow is prevented when the disc is intact. A second flow path is in pneumatic communication with the first flow path and configured to receive gas flow when the first burst disc is ruptured. A second burst disc is disposed in the second flow path and configured to prevent a gas flow while the second burst disc is intact. At an operating pressure, the first burst disc may be punctured by an operator allowing normal use of the system. In the event of a gas overpressure, the first and second burst discs will rupture permitting safe release of the gas.

1. A gas storage system, comprising:
a vessel configured for gas storage under a pressure and having a port; a first flow path in pneumatic communication with the port; a first burst disc disposed in the first flow path such that a gas flow from the vessel in the first flow path is prevented by the first burst disc, a second flow path in pneumatic communication with the first flow path, downstream from the first burst disc with respect to the gas flow, wherein the first burst disc is configured to burst at a first burst pressure only in the first flow path; and a second burst disc disposed in the second flow path such that gas flow from the first flow path to the second flow path is prevented by the second burst disc, the second burst disc configured to burst at a second burst pressure in the second flow path, wherein the second burst pressure is less than the first burst pressure.
