LIQUEFACTION GAS VESSEL

PROBLEM TO BE SOLVED: To provide a liquefaction gas vessel filled with liquefaction gas, for example, such as LP gas (propane gas), capable of taking evaporation heat under a high efficiency while compatibility with the prior art type vessel is being kept.SOLUTION: This invention comprises: an outer container 10 having a top end plate 20, a bottom end plate 30 and a shell 40 and filled with liquefaction gas; an inner cylinder 70 spaced apart from the shell 40, facing against the shell, expanded in a surrounding direction and at the same time extending in an upward or downward direction; a partition plate 90 for parting the inside of the inner cylinder 70 into an upper one and a lower one at the midway position in the upward or downward direction of the inner cylinder 70 and formed with a gas injection port 91 passing in a vertical direction; an interior body 60 just above the partition plate 90 and formed with a liquid circulation port 71 passed through inside or outside of the inner cylinder 70; a flow passage communicating an inside part of the inner cylinder 70 with a space held by the inner cylinder 70 and the shell 40 is arranged above an upper edge 70a of the inner cylinder 70 and a liquid flowing-out passage 81 is arranged at the bottom part of the bottom board 80. 【課題】本発明は、例えばＬＰガス（プロパンガス）などの液化ガスを充填しておく液化ガス容器に関し、従来型の容器との互換性を維持しつつ気化熱を高効率に取り込むことができる液化ガス容器を提供する。【解決手段】天鏡２０と地鏡３０と胴体４０とを有し内部に液化ガスが充填される外装容器１０と、胴体３０との間に間隔を空けて胴体３０に対面して周回方向に広がるとともに上下方向に延在した内筒７０とその内筒７０の上下方向途中位置において内筒７０の内側を上下に仕切るとともに上下に貫通したガス噴出口９１が形成された仕切板９０とを有し仕切板９０の直ぐ上において内筒７０の内外に貫通した液循環口７１が形成された内装体６０と、を備え、さらに、内筒７０の上縁７０ａの上に、内筒７０の内側と、内筒７０と胴体４０とに挟まれた空間とをつなぐ流路を設け、地板８０の底に液流出路８１を設けた。【選択図】 図３
