Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an apparatus for producing carbonated water.

Conventional technology Generally, when carbon dioxide gas and water are brought into contact, the water can absorb carbon dioxide gas until an equilibrium state of H ₂ O + Co ₂ H ₂ CO ₃ is reached, but the reaction until this equilibrium state is reached is slow. So,
Conventionally, as shown in Figure 2, water is supplied in the form of a spray to the upper part of the container tank (a), and carbonated water is produced by increasing the contact with the carbon dioxide gas also supplied to the upper part of the container tank (a). I'm trying to manufacture it.

Problems to be Solved by the Invention In the conventional method described above, water is jetted into the carbon dioxide gas filled in the container tank (a), so in order to increase the contact effect between water and carbon dioxide gas, it is necessary to It is necessary to spray the water into as fine particles as possible in the container tank (a), which causes a large pressure loss, and
In order to increase the production capacity, it was necessary to increase the water supply pressure even higher in order to increase the amount of water supplied, which led to problems such as a decrease in the pressure resistance and safety of the water supply pipe system and joints.

Means for Solving the Problems The carbonated water production device of the present invention includes an orifice in the middle of a conduit whose one end is connected to a water supply source via a water supply solenoid valve and the other end is connected to the upper part of a carbonated water reservoir. A carbon dioxide gas supply pipe connected to the upper part of the carbonated water reservoir via a pressure equalization pipe is connected downstream of the orifice, and carbon dioxide gas is constantly supplied to all piping after the water supply solenoid valve, and carbonated water is The water supply electromagnetic valve is opened and closed via a detector in response to a change in the amount of water in the water reservoir, and while the supplied water passes through the conduit filled with carbon dioxide gas, the orifice acts to reduce the pressure of the flowing water and the ejector action occurs. The synergistic effect of the turbulent flow allows the water to absorb a large amount of carbon dioxide.

Effects With this invention, carbonated water can be produced within the conduit by opening the water supply solenoid valve, and since there is little pressure loss due to the orifice, there is no need to increase the water supply pressure, and carbonated water with a high carbon dioxide content can be produced at low pressure. It can be produced in large quantities, and the produced carbonated water is stored in a water reservoir, which maintains contact with the carbon dioxide gas from the pressure equalizing pipe and the conduit, and the increase in internal pressure due to the carbonated water flowing from the conduit into the water reservoir is absorbed by the pressure equalizing pipe. By discharging and replacing the carbon dioxide gas into the conduit, it is possible to maintain a constant internal pressure during production of carbonated water and improve the dissolution of carbon dioxide gas within the conduit.

Embodiment FIG. 1 is a schematic configuration diagram of an apparatus for carrying out the present invention, in which 1 is a carbonated water storage device, 2 is a carbonated water storage device with one end connected to a water supply source (not shown), and the other end connected to a carbonated water storage device. A conduit 3 connected to the upper part of the vessel is a water supply electromagnetic valve provided in the middle of the conduit 2, and is controlled to open and close via a detector 4 according to changes in the amount of water in the carbonated water reservoir 1. 5 is an orifice installed in the conduit 2 downstream of the water supply solenoid valve 3, and 6 is an orifice with one end connected to a carbon dioxide gas supply source (not shown).
a carbon dioxide gas supply pipe connected to the orifice 5, the other end of which is connected to the conduit 2 downstream from the orifice 5, and
It is also connected to the upper part of the carbonated water reservoir through a pressure equalizing pipe 6a. In FIG. 1, 7 is a take-out pipe attached to the bottom of the carbonated water reservoir, and 8 is a take-out valve.

Carbon dioxide gas is constantly supplied through the carbon dioxide gas supply pipe 6 into all piping after the water supply electromagnetic valve 3 to keep it filled.

The water supply electromagnetic valve 3 is opened when the amount of carbonated water in the carbonated water reservoir 1 reaches a specified lower limit water level, and is closed when the amount of carbonated water in the carbonated water reservoir 1 reaches a specified upper limit water level.

Carbonated water is produced in the conduit 2 by opening the water supply solenoid valve 3, and the produced carbonated water is stored in the carbonated water reservoir 1.

That is, when the water supply electromagnetic valve 3 is opened, the water passes through the orifice 5, is depressurized, and passes through the conduit 2 filled with carbon dioxide gas with a turbulent flow effect, during which the carbon dioxide gas is absorbed into the water. Moreover, orifice 5
Since a carbon dioxide gas supply pipe 6 is connected in the middle of the conduit 2, carbon dioxide gas is sucked into the conduit 2 by the ejector action of the flowing water passing through the conduit 2, thereby increasing the gas content of the carbonated water. It can promote and produce carbonated water with bottom pressure.

In addition, the carbonated water produced in the conduit 2 is stored in the water reservoir 1 and kept in contact with the pressure equalizing pipe 6a and the carbon dioxide gas from the conduit 2, so that the carbonated water flows into the water reservoir 1 and the internal pressure of the water reservoir 1 is maintained. Replacement is performed through the pressure equalizing pipe 6a to keep the internal pressure within a certain limit during production of carbonated water, thereby further improving the production of carbonated water.

Effects of the Invention According to the present invention, there is no large pressure loss as in the conventional high-pressure water spraying method in a container tank, the safety level against damage to equipment is increased at low pressure, and carbonated water with a high gas volume can be produced. It has the advantage of being able to
