Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method and an apparatus for producing ozone-containing water.

[0002]

2. Description of the Related Art At present, ozone, which is a trimer of oxygen atoms, is widely used for disinfection, sterilization and decolorization of tap water and the like. In the case of this ozone, disinfection using conventional chlorine, etc.,
Compared to the sterilization method, there is almost no danger of remaining harmful substances after use, and if there is air and electricity, it can be supplied indefinitely, so storage facilities are not required and space can be saved. There are advantages. In addition, efficient removal of BOD, COD and organic matter as well as microorganisms, fungi and colors, etc. is possible, and there is almost no burden on the environment. Can be used widely.

Since the above-mentioned ozone is generated in the form of gas, it is suitable for use in air, etc.
Prior to its use, the generated ozone had to be dissolved in a suitable solvent such as water. Here, the amount of ozone dissolved in the solvent is a major factor related to the efficiency of subsequent disinfection, sterilization, decolorization, and the like.

The other end of the water pipe 52 is connected to various places (not shown) according to the intended use. The first check valve 54a and the second check valve 54b are
In any case, the flow of the treated water 4 from the first ozone water production tank 22 and the second ozone water production tank 24 to the water distribution pipe 52 is allowed, but the flow in the opposite direction is set to be blocked.

[0019]

Next, the operation of the apparatus for producing ozone water according to the above configuration will be described in relation to the production method. In FIG. 2, while a required amount of treated water 4 is stored in a first ozone water production tank 22,
It is assumed that supply water 2 is stored in 4.

When the power of the ion generator 13 is turned on, ions are generated in the ion generator 13. Next, at the same time as this operation or after a predetermined time delay, the ozone generator 1
2 is turned on, and at the same time, the solenoid valve 14a is opened,
Oxygen flows from the oxygen cylinder 14 into the ozone generator 12. By these series of operations, ions and ozone start to be generated at the same time or ozone is generated with a delay of a predetermined time. Here, instead of oxygen from the oxygen cylinder 14,
Sufficiently dried air may flow from the dehumidifier (air supply port) 16. The oxygen cylinder 1 is connected to the ozone generator 12.
By supplying only oxygen from 4, the generation rate of ozone in the generator 12 can be increased.

At this time, the ions generated by the ion generator 13 ionize the atmosphere in the second ozone water production tank 24 through the second ion electrode 29 and supply water 2 stored in the tank 24. Is rapidly ionized. At this time, since the tank 24 is completely insulated by the insulating portion 24a and the insulator 25, external ionization is prevented, ionization can be efficiently performed only in the tank 24, and the installation position of the ion electrode 29 is By being set at substantially the center of the tank 24, the inside of the tank 24 can be uniformly ionized. The second ozone solenoid valve 34b for supplying ozone to the second ozone water production tank 24 in which the supply water 2 is stored is open,
The ozone generated by the ozone generator 12 is discharged from the second ozone diffusing port 28a via the ozone supply pipe 18 and the second ozone diffusing pipe 28. The first ozone solenoid valve 34a and the first ion supply switch 35a are closed, and ozone and ions are not supplied to the first ozone water production tank 22. The ions supplied from the ion electrode 29 ionize the supply water 2 stored in the second ozone water production tank 24, that is, the tank 24. At the same time, the ozone released from the ozone diffusing holes 28a becomes fine bubbles and dissolves in the supply water 2 and gradually rises while sufficiently contacting the supply water 2. By continuing the supply of ozone and ions in this manner, the ozone concentration in the supply water 2 increases. Moreover, the second ozone water production tank 24
Since the supply water 2 stored therein is ionized, the solubility of ozone is further increased. After a certain period of time, the supply water 2 becomes the treated water 4 containing sufficient ozone.

That is, in the embodiment, since the second ozone diffusing port 28a for supplying ozone is opened at the lower part in the tank, the ozone released from the ozone diffusing port 28a rises to the upper surface of the supply water 2. Supply water 2 for a long time
Contact with. Therefore, the ozone generator 12 does not generate high-concentration ozone, and the ozone of normal concentration is stored in the tank 2.
By supplying the treated ozone water to ozone water 4, high-concentration ozone water (processed water 4) can be produced. As a result, it is possible to suppress the amount of electric power and voltage that increase with the amount of generated ozone, and
The size of the ozone generator 12 can be reduced. Further, by the ionization of the supply water 2, the dissolution of ozone into the supply water 2 can be achieved in a shorter time, and even if the supply of ozone is stopped, the ozone component is not lost from the treated water 4 for a long time.
It can maintain a high ozone concentration.

The ozone not dissolved in the supply water 2 fills the upper space of the second ozone water production tank 24 which is not filled with the supply water 2, and the second exhaust pipe 40b and the exhaust pipe After passing through the catalyst 42a of the exhaust port 42 through 40, ozone is completely decomposed and released to the outside. The ozone not dissolved in the supply water 2 is
By discharging the air into the air without passing through the catalyst 42a, it can be used for sterilization and insecticide in a restaurant kitchen, for example, at night.

During the production of ozone water in the second ozone water production tank 24, the treated water 4 previously stored in the first ozone water production tank 22 can be used. I have. That is, each solenoid valve that is an opening / closing means for various pipes connected to the first ozone water production tank 22 is such that only the first solenoid valve 50a between the air supply pipe 46 and the first air supply pipe 46a is open. I do. The blower 4 is connected to the air blower 46 via the air blower 46 and the first air blower 46a.
The pressure from the tank 8 is increased by the air from the tank 8 being fed into the first ozone water production tank 22, and the treated water 4 is extruded from the first ozone water production tank 22 and is discharged from the first ozone water production tank 22. It is discharged to the outside through the water supply pipe 52a and the water pipe 52, and is used for various purposes. The first check valve 54a is connected to the first ozone water production tank 2.
2 prevents the treated water 4 from flowing backward when the internal pressure of the treated water 2 drops.

The use of the treated water 4 in the first ozone water producing tank 22 is continued, and the level of the treated water 4 falls below the first lower water level sensor 31 in the tank 22 and is detected by the sensor 31. The first solenoid valve 50a is closed and the second
The electromagnetic valve 50b is opened, and the treated water 4 already stored in the second ozone water production tank 24 is supplied to the outside. That is, even if the treated water 4 in the first ozone water production tank 22 is used up, the second ozone water production tank 2
Since the treated water 4 can be continuously supplied from 4, the apparatus can sufficiently cope with a case where a large amount of treated water 4 is required.

In the first ozone water production tank 22,
At the same time as the first solenoid valve 50a is closed, the first solenoid valve 38a for supplying the supply water 2 into the tank 22 is opened, and the supply water 2 is sequentially stored. The amount of water becomes sufficient, and when the water level is detected by the first upper water level sensor 30, the first solenoid valve 38a is closed, and the first solenoid valve 44a for the first exhaust pipe 40a and the first ozone dispersion Trachea 26
First ozone solenoid valve 34a and first ion electrode 27 for
The first ion supply switch 35a is opened, and ozone and ions are supplied to the supply water 2 stored therein similarly to the above-mentioned second ozone water production tank 24, and the treated water 4 sufficiently containing ozone is supplied. Is manufactured. Incidentally, the second solenoid valve 44b, the second ozone solenoid valve 34b, and the second ion supply switch 35b are respectively closed.

In the embodiment, an apparatus having two ozone water production tanks has been described. However, the present invention is not limited to this, and one or three or more tanks may be provided. Further, as a means for supplying the treated water from the tank to the outside, a pump or the like can be used.

[0028]

EXPERIMENTAL EXAMPLES The following experimental examples are given, but the present invention is not limited to the contents disclosed in the experimental examples. (Experimental example) Using the same ozone water producing apparatus as in the example,
The reached ozone concentration was set to 0.05 ml / l, and ozone and ions were supplied to produce ozone water. Then, 30 minutes, 1 hour, 1 hour 30 minutes, 2 hours, and 3 hours after the start of the experiment, and 15 minutes, 30 minutes after the ozone and ion supply were stopped,
The ozone concentration of ozone water produced for a total of 10 times of 1 hour, 1 hour 30 minutes and 2 hours was sampled and measured. The results are as shown in Tables 1 and 2 below. (Comparative Example) With respect to the above-described experimental example, ozone water was produced by supplying only ozone to the supply water. The used device, the reached ozone concentration and the sampling time for measuring the ozone concentration are the same as in the experimental example. The results are as shown in Tables 1 and 2 below.

[0029]

As can be seen from Table 1 showing the results of the experimental example and the comparative example, the time required to reach the expected concentration is longer than that in the case where only ozone is supplied to the supply water and dissolved, and both ozone and ions are mixed. It is faster to dissolve in the feed water, and it is completed in about half the time. Further, as can be seen from Table 2, a decrease in ozone concentration after stopping the aeration shows a better result when ozone and ions are mixed and dissolved. That is, the ratio of the ozone concentration that decreases with the passage of time is small, and the time zone in the practical concentration range is long.

This ozone water is used as agricultural water for, for example, spinach, a pesticide-free vegetable, which has recently attracted attention.
It can be suitably used. In other words, ozone has no residual toxicity and has a bactericidal and insecticidal effect, and can be used in place of pesticides. In addition, since the dissolved ozone concentration is maintained for a long time, it can be used on a vast site. Agricultural applications such as spraying ozone water over time are also possible.

[0032]

[Another Embodiment] As a method for supplying ions to the ozone water production tanks 22 and 24, ion diffusion tubes 60a and 62a may be used instead of the ion electrodes 27 and 29 as shown in FIG. In this case, the ions are supplied to the tanks 22 and 24 with air interposed therebetween. Therefore, the ion generator 13 is designed to supply dry air to an ion generation cell (not shown). It is connected to the dehumidifier 16 via the air supply pipe 66. Here, the ion diffuser tubes 60a and 62a and the ion diffuser ports 60b and 62b are used.
May be subjected to insulation treatment in the same manner as the ozone water production tanks 22 and 24.

The first ion diffuser 60a and the second ion diffuser 62a, which are the ion diffusers, are controlled by a control device (not shown), like the first ozone solenoid valve 34a and the second ozone solenoid valve 34b. The first ion solenoid valve 64a and the second ion solenoid valve 64b communicate with the ion generator 13, which is a source of ions, respectively.
Further, a first ion diffuser 60b and a second ion diffuser 62b for supplying ionized air into the respective production water tanks 22 and 24 are provided at the ends of the ion diffusers 60a and 62a, respectively. I have. Each ion diffuser 60
As b and 62b, as shown in FIG. 5, funnel-shaped ones that easily diffuse ionized air into the atmosphere, for example, are preferably used. However, the method of supplying ions is not particularly limited to this. For example, a conductive part that is not insulated is provided on a part of the outer surface of each of the ozone water production tanks 22 and 24, and the ion is supplied to the conductive part. Can be supplied as long as it is possible to directly contact or jet supply the feed water 2 stored in the tanks 22 and 24.

[0034]

As described above, according to the method and apparatus for producing ozone water according to the present invention, ozone water containing ozone can be produced in a shorter time. And even if the produced ozone water stops the aeration of ozone,
Since it is maintained for a long time, the use time zone is not limited. Further, by shortening the manufacturing time for the production of ozone water, the supply cycle of ozone water can be advanced, and the size of the production apparatus can be reduced, and the production cost can be reduced. Further, since the ozone concentration is maintained irrespective of the aeration, there is an effect that it can be suitably used for producing low-concentration ozone-containing water having a low sterilizing effect and an oxygen supplying effect.
