Abstract
A circulating inset-gas seal system based on gas-supply servo device and QHSE based storage and transportation method are provided. The gas-supply servo device includes a servo constant pressure unit including: inlet gas compressors a charging check valve, a gas supply container and a degassing valve control unit which are connected in sequence and communicated and controlled by a one-way valve. According to a preset gas pressure of the gas phase space in the material container, a inert sealing medium filled in the material container group is received, stored and released via an inerting pipe to form a station-type circulating inert seal system. A multi-group circulating inerting system cooperates with a mobile material container for self-sealing loading and unloading, which is capable of realizing a QHSE storage and transportation system with no gas phase emission.
