DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a carbonated spring producing apparatus according to the present invention will be described in detail with reference to the drawings. Needless to say, the present invention is not limited to the following embodiments.

FIG. 1 is a schematic view showing a carbonated spring producing apparatus using an example of the present invention. In this system, as shown in FIG. 1, the combustion gas 10 from the means (carbon dioxide gas supply means) 1 for obtaining the combustion gas 10 containing carbon dioxide gas,
After the carbon dioxide concentration means 2 is concentrated, the concentrated carbon dioxide gas is dissolved in the bath water of the bath 4 under pressure by the dissolution means (carbon dioxide pressure dissolution means) 3 and is also made into fine bubbles to form a fine bubble carbonated spring. It is designed to be supplied to the bathtub 4.

In the combustion gas supply means 1, the combustion gas 10 containing carbon dioxide gas is generated in the water heater 20 using city gas as fuel.

A valve 90, a heat exchanger 5 for cooling, a blower 15 for supplying combustion gas, a steam removing tower 61, and a valve 92 are installed in this order between the water heater 20 and the carbon dioxide adsorption tower 62. .

Combustion gas 10 supplied from the water heater 20
Since the temperature is high, if it is supplied to the carbon dioxide adsorption tower 62 as it is, the temperature swing system in which the adsorption / desorption reaction in the carbon dioxide adsorption tower 62 is performed by utilizing the temperature difference at the time of adsorption / desorption cannot be carried out. Therefore, the combustion gas 10 is cooled in advance by the heat exchanger 5 in the preceding stage of the adsorption tower and sent to the carbon dioxide adsorption tower 62 by the blower 15.

The steam removing tower 61 of the concentrating means 2 contains activated alumina (steam adsorbent) 191 and a heater 81 for regenerating the adsorbent. Further, a temperature sensor 71 that detects the internal temperature is installed inside, and the controller 30 controls the internal temperature.

The water generated when the water vapor removal tower 61 is regenerated is discharged through the valve 91.

The carbon dioxide adsorption tower 62 contains zeolite (carbon dioxide adsorbent) 192 and a heater 82 for desorbing adsorbed carbon dioxide.

The temperature measurement signal of the temperature sensor 72 provided in the adsorption layer is fed back to the controller 30 via the data bus 32, and the temperature in the adsorption tower 62 is maintained at a predetermined temperature.

The outlet of the carbon dioxide adsorption tower 62 communicates with the dissolving means 3 and also communicates with the outside air through a valve 94 and a valve 90 through a valve 93.

The dissolving means 3 is provided with a piping system through which the bath water in the bathtub 4 circulates along the path indicated by the arrow a. That is,
By the action of the pressure pump 12, the bath water enters from the suction port 13, passes through the pressure pump 12 and the accumulator 11 having a gas separation function, and returns from the fine bubble generating nozzle type discharge port 14 to the bath 4. It has been done.

The undissolved gas removed by the accumulator 11 is released to the outside air through the valve 96 or returned to the piping system through the valve 97. Also, outside air can be introduced into the piping system through the valve 98.

Next, a series of processes for producing a carbonated spring will be described. In the adsorption process, the water heater 20
The combustion gas 10 generated in 1 is cooled in the heat exchanger 5 and dehumidified in the water vapor removal tower 61, then introduced into the carbon dioxide adsorption tower 62, and the carbon dioxide is adsorbed and separated by the carbon dioxide adsorbent 192, and the remaining The adsorbed gas 24 is discharged from the valve 94.

Next, when the bather requests the operation of the carbonated spring from the display operation panel 31, the controller 30 activates the desorption process and turns on the heater 82 in the carbon dioxide adsorption tower 62.

When the temperature in the tower rises, carbon dioxide gas is quickly desorbed, and the concentrated carbon dioxide gas 25 is pressure-dissolved in the bath water through the valve 95 in the middle of the piping system.

After that, the discharge port 1 of the fine bubble generating nozzle type
4, the bath water is decompressed, the dissolved carbon dioxide gas appears as fine bubbles in the bath water, and fine bubble carbonated springs appear in the bath 4.

During this period, the controller 30 grasps the remaining amount of carbon dioxide gas based on the cumulative operation time of the carbonated spring, and displays the remaining amount display step by step on the LED or LCD on the display operation unit 31.

An alarm may be sounded when the remaining amount of carbon dioxide gas is low.

When the remaining amount of carbon dioxide gas is exhausted, the combustion gas supply means 1 may be started again to control the concentration of carbon dioxide gas.

The carbon dioxide remaining amount during the operation of the carbonated spring is managed and displayed by the integrated operation time of the carbonated spring as described above. At this time, the completion of desorption of carbon dioxide is indicated by the carbon dioxide adsorption tower 62.
It is more reliable to make a distinction based on the internal temperature.

That is, when the temperature inside the tower reaches a predetermined temperature, the controller 30 determines that the desorption of carbon dioxide gas is completed and stops the desorption process. For the relationship between the completion of carbon dioxide desorption and the temperature in the carbon dioxide adsorption tower 62, data determined for each scale of the device is used.

Depending on the cumulative operating time of the carbonated spring,
By assuming some precision, it is possible to grasp the completion of desorption of carbon dioxide.

In the case of the apparatus shown in this embodiment, the operation control of the heat exchanger, each valve, the heater, the pump, etc. is automatically grasped by the controller 30 equipped with various sensors and a microprocessor. Although it is controlled, managed, and can be operated unmanned, it is not limited to this and may be partially operated manually by a bather or the like.

Further, in the configuration of FIG. 1, when the desorption process is started, the temperature inside the tower is detected by the temperature sensor 72, which is converted into the amount of desorbed carbon dioxide in the controller 30, and on the display operation unit 31. Another embodiment is one in which the amount of carbon dioxide gas remaining is displayed stepwise on the LED, LCD, or the like.

In the case of this embodiment, the carbon dioxide desorption process and its completion are all judged by the temperature inside the carbon dioxide adsorption tower 62.

Carbon dioxide desorption process: The relationship between the completion of carbon dioxide desorption and the temperature in the carbon dioxide adsorption tower 62 uses data as illustrated in FIG. 2 which is determined for each scale of the apparatus.

[0048]

As described above, in the carbonated spring producing apparatus of the present invention, the carbonated spring operating time, the temperature inside the carbon dioxide adsorption tower or the operating time of the carbon dioxide adsorption tower and the inside temperature of the carbon dioxide adsorption tower are measured. The amount of carbon dioxide gas that can be desorbed during the operation of the carbonated spring can be grasped and managed with a simple structure, and if a suitable display device is used, the user such as a bather can be notified directly.

It is easy to grasp, manage, and display the amount of desorbable carbon dioxide during the operation time of the carbonated spring, but desorption completion is grasped, managed, and displayed by the temperature inside the carbon dioxide adsorption tower. Is sure to do. Therefore, it is more preferable to grasp and display the amount of desorbable carbon dioxide gas by the combination of both.
