<P>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. <P>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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
