However, in the above configuration, the concentration of carbon dioxide in the combustion gas coming into contact with the water supplied from the water supply passage 4 has a constant value (5) in order to maintain stable combustion. ８8%), and it was difficult to increase the concentration.

When a large amount of carbon monoxide is generated due to the failure of the combustion means 2, the concentration of carbon dioxide in the combustion gas decreases, and the carbon dioxide in the combustion gas is brought into contact with the combustion gas and water. High concentrations could not be obtained even after dissolution.

Further, when the combustion gas containing carbon monoxide is supplied together with hot water from the hot water supply channel 5, the concentration of carbon monoxide at the hot water outlet increases, which is not hygienic.

Is to increase the dissolving efficiency of carbon dioxide dissolved in hot water or water, to increase the concentration of dissolved carbon dioxide contained in hot water or water, and to prevent nitrogen oxides in the combustion gas from being dissolved in the hot water or water. .

A third object of the present invention is to remove nitrogen oxides contained in the combustion gas and remove the carbon monoxide contained in the combustion gas in which the concentrations of carbon dioxide and carbon monoxide in the combustion gas are increased. By converting it to carbon dioxide, a combustion gas with a higher concentration of carbon dioxide is obtained, and the dissolved carbon dioxide contained in the hot water or water is increased by increasing the dissolving efficiency of carbon dioxide dissolved in the hot water or water brought into contact with the combustion gas. Increases the gas concentration and prevents the concentration of carbon monoxide in the air at the tapping point from rising even when the combustion gas is supplied together with the hot water or water, and prevents the nitrogen oxides in the combustion gas from being dissolved in the hot water or water.

[0010]

In order to solve the above-mentioned problems, the first means of the carbonated spring manufacturing apparatus according to the present invention comprises a hot water supply passage through which hot water or water passes, and a combustion gas through which a combustion gas containing carbon dioxide passes. An introduction path, a combustion gas introduction means provided in a hot water supply path for introducing the combustion gas supplied from the combustion gas introduction path into the hot water supply path and dissolving carbon dioxide in the combustion gas in hot water or water, Gas-liquid separation means provided downstream of the water supply hot water supply path of the combustion gas introduction means for separating water and residual combustion gas not dissolved in the hot water or water, and gas-liquid separation of the residual combustion gas separated by the gas-liquid separation means It has a discharge path for discharging from the means and an oxidation catalyst provided in the combustion gas introduction path.

In order to achieve the second object, the second means of the carbonated spring manufacturing apparatus according to the present invention comprises a hot water supply passage through which hot water or water passes, and a combustion gas introduction passage through which a combustion gas containing carbon dioxide passes. The combustion gas supplied from the combustion gas introduction path is introduced into the hot water supply path, and the carbon dioxide in the combustion gas is dissolved in the hot water or water. Gas-liquid separation means provided downstream of the hot water supply path of the combustion gas introduction means for separating the residual combustion gas not dissolved in the hot water or water, and the residual combustion gas separated in the gas-liquid separation means from the gas-liquid separation means. It has a discharge path for discharging and a denitration catalyst provided in a combustion gas introduction path.

In order to achieve the third object, a third means of the carbonated spring manufacturing apparatus according to the present invention comprises a hot water supply passage through which hot water or water passes, and a combustion gas introduction passage through which a combustion gas containing carbon dioxide passes. Means for introducing combustion gas supplied from the combustion gas introduction path into the hot water supply path and dissolving carbon dioxide in the combustion gas in the hot water or water; Gas-liquid separation means provided downstream of the hot water supply channel of the combustion gas introduction means for separating residual combustion gas not dissolved in hot water or water, and residual combustion gas separated in the gas-liquid separation means is discharged from the gas-liquid separation means. A denitration catalyst provided in the combustion gas introduction passage, and an oxidation catalyst provided in the combustion gas introduction passage downstream of the denitration catalyst.

[0013]

According to the present invention, the first means produces a combustion gas containing carbon dioxide by the combustion means. The combustion gas containing carbon dioxide is guided from the combustion gas introduction path to the combustion gas introduction means. By the oxidation catalyst provided in the middle of the combustion gas introduction path, carbon monoxide contained in the combustion gas is converted into carbon dioxide, and the concentration of carbon dioxide in the combustion gas is increased. On the other hand, hot water or water is supplied to the combustion gas introducing means via a hot water supply channel. In the combustion gas introducing means, hot water or water and a combustion gas having an increased concentration of carbon dioxide are mixed and heat exchanged, and at the same time, highly water-soluble carbon dioxide in the combustion gas dissolves to become hot water containing carbon dioxide gas. Thereafter, the residual combustion gas not dissolved and the hot and cold water in which the carbon dioxide gas is dissolved are separated by the gas-liquid separation means, and the residual combustion gas is discharged from the gas-liquid separation means via the discharge path. Hot water containing carbon dioxide gas comes out of the gas-liquid separation means and is supplied to a predetermined place such as a shower or a bath via a hot water supply channel. Since carbon monoxide is eliminated by the oxidation catalyst, carbon monoxide is not mixed with hot water or water. Further, since the concentration of carbon dioxide in the combustion gas is increased, the efficiency of dissolving carbon dioxide in hot water or water is increased.

[0014] In the second means of the present invention, nitrogen oxides such as nitrogen dioxide contained in the combustion gas are adsorbed by a denitration catalyst provided in the middle of the combustion gas introduction path, and the nitrogen oxide hot water or water Dissolution in the water is eliminated. In addition, the concentration of carbon dioxide in the combustion gas is increased by an amount corresponding to the disappearance of the nitrogen oxides, and the efficiency of dissolving carbon dioxide in hot water or water is increased.

[0015] In the third means of the present invention, nitrogen oxides such as nitrogen dioxide contained in the combustion gas are adsorbed by the denitration catalyst provided in the middle of the combustion gas introduction path, and the nitrogen oxide is removed. Only the concentration of carbon dioxide and carbon monoxide in the combustion gas increases.

The combustion gas free of nitrogen oxides is then passed through an oxidation catalyst to convert carbon monoxide to carbon dioxide. By passing the oxidation catalyst after removing the nitrogen oxides with the denitration catalyst, the oxidation catalyst does not need to convert nitrogen monoxide to nitrogen dioxide, and carbon monoxide can be efficiently converted to carbon dioxide by that much. The concentration of carbon dioxide in the combustion gas is increased by the amount that the nitrogen oxides have disappeared and the amount that the carbon monoxide has been converted, and the dissolving efficiency of carbon dioxide in hot water or water is further increased. Also, mixing and dissolving of nitrogen oxides and carbon monoxide in hot water or water are eliminated.
