PROBLEM TO BE SOLVED: To provide a method and apparatus for efficiently producing a high concentration carbonate spring and preventing the discharge of undissolved carbon dioxide gas, while having a simple structure, since there is the risk of discharging undissolved carbon dioxide gas together with the carbonated spring by an apparatus with simple structure when a high concentration carbonate spring is produced by dissolving carbon dioxide gas into warm water.SOLUTION: Using a container for storing carbon dioxide gas in the upper part and warm water in the lower part, a suitable amount of carbon dioxide gas is injected into the warm water sent to the container to make a gas-liquid mixture flow. Further, the gas-liquid mixture flow is jetted into the warm water in the container from the upper part of the container to make a state wherein the carbon dioxide gas in the upper part of the container is involved in to make the warm water bubble by the carbon dioxide gas. By widely increasing the contact area between the warm water and the carbon dioxide gas, the carbon dioxide gas can be efficiently dissolved into the warm water even under low pressure. Further, a method not to discharge undissolved carbon dioxide gas and an apparatus with simple structure are provided.COPYRIGHT: (C)2012,JPO&INPIT【課題】 温水に炭酸ガスを溶解して高濃度の炭酸泉を生成する場合、シンプルな構造のものは未溶解の炭酸ガスが炭酸泉と共に排出されるため危険であり、シンプルな構造で効率よく高濃度炭酸泉を生成し、未溶解の炭酸ガスを排出しない方法と装置が求められている。【解決手段】 容器内の上部に炭酸ガス、下部に温水を貯留する容器を用い、容器に送水されるお湯に適量の炭酸ガスを注入し気液混合流とし、さらに、その気液混合流を容器上部から容器内の温水に向かって噴射することにより、容器上部の炭酸ガスも巻き込んで容器内の温水が炭酸ガスで泡立つ状態を作り、温水と炭酸ガスの接触面積を大幅に増やして、低圧下でも炭酸ガスを温水に効率よく溶解できるようにし、さらに、未溶解の炭酸ガスも排出しない方法とシンプルな構造の装置を提案するものである。【選択図】図1
