PROBLEM TO BE SOLVED: To efficiently provide a carbonated spring high in carbon dioxide melting concentration, having superfine foam particles and the long duration of a foaming effect and facilitating the selective use of carbonated water of preferred pH.SOLUTION: An acidic solution with acid such as citric acid or succinic acid dissolved in water, and an alkaline solution with alkali such as sodium bicarbonate or sodium carbonate dissolved in water, are put in an acidic solution storage tank and an alkaline solution storage tank that are set on a base. A pair of storage tanks containing the acidic solution and the alkaline solution are connected to a carbon dioxide generating tank of inner-outer double structure of spherical shape or the like through delivery pipes respectively extending downward. The distal ends of the respective delivery pipes are arranged in bent facing proximity while facing close to the lower part of an inner wall surface in an inner tank of the carbon dioxide generating tank. The acidic solution and the alkaline solution ejected from the facing distal ends of the respective delivery pipes directly contact and react to generate carbon dioxide. The carbon dioxide and water pass through the inside of fiber of a disposed mat, and are mixed and stirred and fed into an outer tank from small holes to become a carbonated spring.COPYRIGHT: (C)2014,JPO&INPIT【課題】 炭酸ガス溶解濃度が高く、発泡粒子も超微細で、発泡効果の持続時間も長く、好みのPHの炭酸水の選択使用も容易にできる炭酸泉を効率的に得る。【解決手段】基台上にセットされた酸性溶液収容タンクとアルカリ性溶液収容タンクに、クエン酸、コハク酸等の酸を水に溶解させた酸性溶液と重曹、炭酸ナトリウム等のアルカリを水に溶解させたアルカリ性溶液を入れる。この酸性溶液とアルカリ性溶液を入れた一対の収容タンクは夫々下方に延びる送出管を介して球形等の内外二重構造の炭酸ガス発生タンクに接続する。各送出管先端部は炭酸ガス発生タンクの内側タンク内の内壁面下方近くにまで臨んで屈曲対向近接配置される。この対向する各送出管先端部から吐出する酸性溶液とアルカリ性溶液とは直接に接触反応して炭酸ガスが発生する。炭酸ガスと水は配設されたマットの繊維内を通過して混合攪拌され小孔より外側タンク内へと送られて炭酸泉となる。【選択図】図1
