Abstract

PURPOSE:To allow water to absorb a large amount of carbon dioxide, by providing an orifice on the way of the conduit connecting a water supply source and a calcareous water reservoir and connecting a carbon dioxide pipe to the downstream of the orifice. CONSTITUTION:When a water feed solenoid valve 3 is opened, water passes through an orifice to be reduced in pressure and passes through a conduit 2 filled with carbon dioxide, while accompanies turbulent flow action, to absorb carbon dioxide during this period. At this time, carbon dioxide is sucked into the conduit 2 by the ejector action of flowing water passing through said conduit 2 to promote the increase in gas content of carbonated water. The increase in the internal pressure of a water reservoir by the inflow of carbonated water leads out carbon dioxide to the conduit 2 from a pressure equalizing pipe 6a to substitute the same with carbonated water and keeps internal pressure during the manufacturing of carbonated water constant and enhances the dissolution of carbon dioxide in the conduit 2. By this method, calcareous water with a high gas volume can be prepared even if water feed pressure is low and, therefore, the safety degree to the damage of an equipment material is increased.

Description

[Detailed description of the invention] Retired Emperor of Industry Ri Gongbeard This invention relates to a method for producing carbonated water.

When carbon dioxide gas and water come into contact with each other, H, O+GO,
Carbon dioxide gas can be absorbed into water until it reaches an equilibrium state of Supply water to the improvement part in the form of mist,
Similarly, carbonated water is produced by increasing the contact action with the carbon dioxide gas supplied to the upper part of the container tank (a).

, IM1.・In the conventional method described above, water is spouted into the carbon dioxide gas filled in the container tank (a). Therefore, in order to increase the contact effect between water and carbon dioxide gas, it is necessary to pour water into the container tank (a). a5) It is necessary to make the particles as fine as possible and spray them, which causes a large pressure loss.Also, in order to increase the production capacity, it is necessary to increase the water supply pressure to increase the amount of water supplied. There were problems such as a decrease in pressure resistance and safety of the water supply pipe system and the joint part.

° Tanoko's method for producing carbonated water according to the invention includes providing 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, and carbon dioxide gas is constantly supplied to all piping after the water supply solenoid valve, thereby controlling the amount of water in the carbonated water reservoir. The water supply solenoid valve is opened via the detector, and while the water passes through the conduit filled with carbon dioxide gas, the synergistic effect of the pressure reduction effect of the orifice, the ejector action, and the turbulent flow within the conduit causes the water to flow through the conduit filled with carbon dioxide gas. It is made to absorb a large amount of carbon dioxide gas.

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 a large amount of carbonated water with high carbon dioxide gas content can be produced at low pressure. The produced carbonated water is stored in a water reservoir and kept in contact with the carbon dioxide gas coming from the pressure equalizing pipe and the conduit, and the internal pressure increase due to the carbonated water flowing from the conduit into the water reservoir is absorbed by the pressure equalizing pipe. By discharging and replacing carbon dioxide gas into the conduit, it is possible to maintain a constant internal pressure during production of carbonated water and to improve dissolution of carbon dioxide gas within the conduit.

(3) is a water supply solenoid valve installed in the middle of the conduit (2), and the other end is connected to the upper part of the carbonated water reservoir (1). Opening/closing is controlled via a detector (4) according to changes in the amount of water inside. (5) is an orifice installed in the conduit (2) downstream of the water supply solenoid valve (3), and (6) is a carbon dioxide gas supply pipe with one end connected to a carbon dioxide gas supply source (not shown). The other end is connected to the conduit (2) downstream from the orifice (5), and is also connected to the upper part of the carbonated water reservoir (1) through a pressure equalization pipe (6a). In Figure 1, (7) is the carbonated water reservoir (1
) is the take-out pipe attached to the bottom of the pipe, and (8) is the take-out valve.

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

The water supply solenoid 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 solenoid valve (3) is opened, the water passes through the orifice (5), is depressurized, and flows into the conduit (
2) Passes through the water with turbulence, during which carbon dioxide gas is absorbed by the water.

Moreover, since the carbon dioxide gas supply pipe (6) is connected to the middle of the conduit (2) after the orifice (5), the conduit (2)
Due to the ejector action of the running water passing through the pipe, carbon dioxide gas is released into the conduit (
2) It can be sucked into the carbonated water to promote the increase in gas content of carbonated water and produce carbonated water at low pressure.

Also, the carbonated water produced in the conduit (2) is stored! 1 (1
), and maintains contact with carbon dioxide from the pressure equalization pipe (68) and conduit (2). By doing this, the internal pressure during carbonated water production is kept within a certain limit, and the production of carbonated water is further improved.

According to this invention, there is no large pressure loss as in the conventional high-pressure water spraying method in a container tank, and the safety level against damage to equipment is increased due to low pressure. It has the advantage of being easy to manufacture.
