A evaporative gas reliquefying plant which has a condensation mixture device and this
Document Type and Number:
Japanese Patent JP6090616
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a condensing mixing device for effectively re-liquefying a boil-off gas, and a boil-off gas re-liquefying device having the same.SOLUTION: In a condensing mixing device which has a Venturi tube-type flow tube 7, and in which steam holes 10-1, 10-2, ... facing a radial direction and a downstream direction of the flow tube for injecting steam from the outside of the flow tube into the flow tube, are formed on a plurality of positions in an axial direction of the flow tube so that injection openings are formed on an inner diameter face of an expanded-diameter portion 7C, and the steam is injected from the injection openings of the steam holes to a low-temperature liquid flowing downstream in the flow tube so that the steam is condensed and mixed with the low-temperature liquid, the expanded-diameter portion has step portions 10B-1, 10B-2, ... on a plurality of positions in the axial direction, has stepped expanded-diameter portions 7C-1, 7C-2, ... having inner peripheral faces successively expanded in diameter at the step portion and extended to a downstream side in the axial direction, a radius of the stepped expanded-diameter portion of one stage is constant in the axial direction and forms a cylindrical inner face, and an inner diameter of the stepped expanded-diameter portion at a most downstream side, is smaller than an inner diameter of an inlet portion 6A of the flow tube.SELECTED DRAWING: Figure 2
