CIRCULATING INERT-GAS SEAL SYSTEM BASED ON GAS-SUPPLY SERVO DEVICE AND THEREON BASED STORAGE AND TRANSPORTATION METHOD

摘要

A circulating inset-gas seal system based on gas-supply servo device (A) are provided. The gas-supply servo device (A) includes a servo constant pressure unit including: inlet gas compressors (A1) a charging check valve (A2), a gas supply container (A3) and a degassing valve control unit (A4) 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 (U), an 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.
