LIQUID-SEALED FLUID CONTAINER-BASED CYCLIC INERT SEALING SYSTEM AND QHSE STORAGE AND TRANSPORTATION METHOD

摘要

A liquid-sealed fluid container, comprising: a container body (1), which is internally provided with a sealing space, used for holding a fluid material (2); a working medium liquid (3), which is oxygen-injected into the sealing space, in liquid phase communication with a working medium liquid source outside the container body, and used for forming a liquid lining structure for the fluid material within the sealing space, so as to isolate the fluid material (2) within the sealing space from an external gas phase atmosphere of the container body (1); a material transfer control unit, which is in communication with the fluid material (2) within the sealing space, and used for controlling the input and output of the fluid material (2) within the sealing space, the working medium liquid (3) being incompatible or substantially incompatible with the fluid material (2) within the sealing space, the density of the working medium liquid (3) being greater than the density of the fluid material within the sealing space. The present invention also relates to a liquid-sealed fluid container-based cyclic inert sealing system and a QHSE storage and transportation method, said system being capable of safely and effectively transporting and storing the fluid material (2).
