Abstract: The three-stage axial flow degassing device adopts an efficient degassing technology including a vertical high speed swirling field, a horizontal rapid axial flow field and a vertical reversing scrubbing field formed by a combination of vertical tubes; the first-stage degasser performs the first-stage segmental vertical high speed swirling degassing operation, removes the gas phase carried by the gas-containing fluid, and forms a primary gas and a primary fluid; the microporous uniform mixer breaks bubbles of the primary fluid and forms a gas-liquid uniform mixed flow; the second-stage degasser performs the second-stage horizontal vane wheel swirling generating rapid axial flow degassing operation, removes the gas phase carried by the gas-liquid uniform mixed flow, and forms a secondary gas and a secondary fluid; the third-stage degasser performs the third-stage vertical reversing deep degassing operation, removes liquid phase carried by the secondary gas, and forms a tertiary gas and a tertiary fluid.
