Abstract

PURPOSE:To form carbonated water of a high concn. with a simple and compact device by feeding carbon dioxide into the hollow of a hollow yarn type semipermeable membrane and dispersing and absorbing the carbon dioxide via the hollow yarn type semipermeable membrane into the water flowing in contact with the surface of the hollow yarn type semipermeable membrane. CONSTITUTION:This device has a suction pump 4 which circulates and passes hot water 2 in a bath tub 1 through a conduit 3, a dispersing device 5 having the hollow yarn type semipermeable membrane 51 the surface of which comes into contact with the circulating hot water 2, and a carbon dioxide cylinder 7 which feeds the carbon dioxide via the conduit 6 into the hollow of the hollow yarn type semipermeable membrane 51 and disperses and absorbs the carbon dioxide into the hot water 2 circulating and flowing via the hollow yarn type semipermeable membrane 51. The ratio of the volume of the water to be passed in the dispersing device 5 while maintaining the contact with the hollow yarn type semipermeable membrane 51 and the amt. of the carbon dioxide to be supplied is preferably kept set in a 5 to 300% range of the theoretical saturation solubility in the dispersing device. The carbon dioxide permeates the hollow yarn type semipermeable membrane in the form of fine bubbles when the carbon dioxide is fed into the hollow of the hollow yarn type semipermeable membrane. Then the carbon dioxide dissolves into the water to carbonate the water which flows in the hollow yarn type semipermeable membrane by coming into contact with the surface of this membrane.

（従来の技術） 炭酸泉は、優れた保温作用があることから、古くから温
泉を利用する浴場等で多く用いられている。(Prior Art) Carbonated springs have been widely used in bathhouses and the like that use hot springs since ancient times because of their excellent heat-retaining properties.

があるとされている。In particular, the heat-retaining effect of carbonated springs is thought to be basically due to the improvement of the physical environment due to the peripheral vasodilation effect of the carbon dioxide gas it contains. In addition, percutaneous penetration of carbon dioxide gas causes an increase and dilation of the capillary bed, promoting blood circulation in the skin. Therefore, it is said to be effective in treating degenerative lesions and peripheral circulation disorders.

にしていた。Because carbonated springs have such excellent effects, attempts have been made to artificially prepare carbonated springs. For example, a method of bubbling carbon dioxide gas in a bathtub, a chemical method of causing carbonate and acid to interact in a bathtub to generate carbon dioxide gas, and a method of pressurizing hot water and carbon dioxide gas in a tank for a certain period of time to generate carbon dioxide gas. Carbonated hot water was obtained by methods such as absorbing carbonated carbonate into hot water.

た。[Problem to be solved by the invention] However, in all conventional methods for producing carbonated hot water, the dissolution rate of carbon dioxide gas in hot water is low, and it is said that the concentration of carbon dioxide gas dissolved in hot water cannot be sufficiently increased. There was a problem.

例えば、錠剤を用いる方法では、上述した炭酸泉として

い。For example, in a method using tablets, in order to ensure a concentration of carbon dioxide gas of 300 ppm or more that exhibits the above-mentioned effect as a carbonated spring, a large number of tablets must be added.

は困難であった。In addition, in the method of bubbling carbon dioxide directly into the bathtub, in order to achieve a carbon dioxide concentration of 300 ppm in hot water at 40'C, the dissolution rate of carbon dioxide (when absorbed by hot water) is 1.
It was found that it was only about 0%, and most of the carbon dioxide gas was dissipated. In addition, by increasing the contact area between carbon dioxide gas and water using air stones, sintered metal pipes, etc., and increasing the carbon dioxide concentration to 300 ppm in hot water at 40°C, carbon dioxide gas can be absorbed. Although the dissolution rate increased to approximately 50%, it was difficult to ensure a higher dissolution rate.
