More specifically, the present invention relates to an apparatus for producing ozone-dissolved water by forcibly bringing water into contact with ozone.

[Prior art] Conventional ozone-dissolved water production equipment supplies ozone from near the bottom of stored water, contacts the water with ozone bubbles rising in the water, and thereby dissolves ozone in the water. It is known to cause

[Problems to be solved by the invention] However, when using the conventional method, the contact between water and ozone was not forced or positive, and the contact area between water and ozone was extremely limited. could not be sufficiently dissolved in water, making it difficult to increase the ozone dissolution rate. Furthermore, in the conventional method for producing ozone-dissolved water, it has been difficult to freely adjust the ozone dissolution rate. Therefore, it has been difficult to obtain ozone-dissolved water suitable for various uses.

[Object of the invention] The object of the present invention is to solve the above-mentioned problems and provide an ozone-dissolved water production device that can freely increase the ozone dissolution rate and easily adjust the ozone dissolution rate. .

[Means for Solving the Problems] In order to achieve the above object, the ozone-dissolved water production device according to the present invention includes a mixing chamber for contact-mixing water and ozone, and a mixing chamber for mixing water with fine particles. The apparatus is constructed of a crushing means for pulverizing, a means for pumping water connected to the crushing means, and a means for pumping ozone connected to a mixing chamber.

[Example] Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a conceptual diagram showing the flow of water and ozone by the ozone-dissolved water production apparatus according to the present invention.
Reference numeral 1 denotes a water source, which is connected to a pressure feeding means 4 via a valve 2 and a filter 3, and further includes a water flow regulating valve 5,
It is connected to a mixing chamber 7 via a flow meter 6. The pressure feeding means 4 sucks water from the water source 1 and sends the water into the mixing chamber 7, and is specifically, for example, a pump.

On the other hand, 10 is an ozone source, specifically oxygen or air. This ozone source 10 is connected to an ozonizer 14 via a pressure feeding means 11, a valve 12, and a filter 13, and is further connected to the mixing chamber 7 via an ozone amount adjustment valve 15. Here, if compressed oxygen is used as the ozone source 10, the following effects can be obtained. In other words, highly pure oxygen packed in a cylinder can be used, the effort and cost of producing ozone from air can be saved, and ozone can be easily obtained. The effort and cost of specially providing the pressure feeding means 11 can also be saved. Furthermore, it is possible to prevent the generation of nitrogen oxides when producing ozone from air.
It has various advantages such as eliminating toxicity. The ozonizer 14 is a general ozone production device using silent discharge, but here a creeping discharge type using electrodes printed on a high purity alumina ceramic layer is adopted. Ozone source 10 is filter 1
After the dust is removed through the ozonizer 14
A portion of the ozone is converted into ozone by the process, and the ozone is sent into the mixing chamber 7 together with the remaining oxygen that has not been ozonated.
The pumping means 11 for this feeding is a compressive force attached to the ozone source 10.

Next, Figure 2 shows one of the crushing means for turning water into fine particles.
An example is shown. The crushing means 8 is composed of a large number of nozzles arranged on the entire wall surface of the mixing chamber 7. In FIGS. When the mixture is fed under pressure, it is ejected from a large number of nozzles arranged on the entire wall surface of the mixing chamber 7, and is atomized into a mist, which fills the mixing chamber 7. On the other hand, ozone is in the mixing chamber 7,
The particles violently collide with the water particles that are pumped into the same chamber 7, scatter, and collide with each other, and come into contact with extremely high-density, multifaceted mist water. As a result, the particulate water becomes water droplets containing a large amount of ozone dissolved therein and accumulates at the bottom of the mixing chamber 7, and is supplied from the outlet 9 as highly concentrated ozone-dissolved water. In this case, the water pumping means 4, the ozone pumping means 11, the ozonizer 1
4, or by adjusting the power factor of the crushing means 8, the ozone amount adjustment valve 15, and the water amount adjustment valve 5,
It is possible to adjust the rate of ozone dissolution in water.

Next, FIG. 3 is a conceptual diagram showing another embodiment. In this second embodiment, the water source 1 is the ozone-dissolved water produced in the first embodiment, and generally the ozone-dissolved water is reused again. By mixing it with ozone, the ozone concentration is increased. In this case, it is also possible to simply circulate the ozone-dissolved water produced in the first embodiment in the same production equipment, but in the second embodiment described here, as shown in FIG. The water source 1 is temporarily stored in a water tank 20 via a valve 2 and a filter 3. In the water storage tank 20, the mixing chamber 7 is installed together with the crushing means 8, and the outlet 9 of the mixing chamber 7 is connected to a submersible pipe 21, which extends to the bottom of the water tank 20. He was released at the same location. In other words, the ozone-dissolved water coming out of the outlet 9 is sent to the underwater pipe 21.
It is guided to the bottom of the water tank 20 by.
The water tank 20 is a water level adjustment tank 22 installed nearby.
and are connected to each other by a plurality of communication pipes 23 provided above and below the side walls of the water tank. A level switch 24 is attached to the water level adjustment tank 22, and from the same level switch 24, a number of level sensors 25 equal to the number of communicating pipes 23 can detect the water surface slightly below the lowest end of each communicating pipe 23. Each of them is growing like this. The water level sensed by the level sensor 25 sends a signal to the valve 2 connected via the level switch 24, so that the valve 2 is opened or closed at each stage of the water level. Note that the valve 2 here is a solenoid valve. In addition, an overflow pipe 2 is connected from near the upper edge of the water level adjustment tank 22.
9 is pulled out to allow excess water to drain.

When the water exits from the drain port 26 opened at the lowermost position of the water level adjustment tank 22, it is sucked into the pressure feeding means 4 if the water tap 27 or water tap 28 installed at the end of the T-shaped pipe is closed. It is designed to be The pressure feeding means 4 feeds the sucked water into the mixing chamber 7 again, and the water is pulverized into fine particles through the crushing means 8 and brought into forced contact with the ozone in the mixing chamber 7 again. In this way, ozone can be repeatedly increased in dissolved concentration.
When using ozone-dissolved water, the pot 27 is opened and the water tap 28 is operated.

Note that if both the water tap 28 and the valve 2 of the water source 1 are closed, the circulation of the ozone-dissolved water can be repeated infinitely, so that the ozone dissolution rate can be increased.

Next, FIG. 4 is a conceptual diagram showing the third embodiment. This third embodiment is an ice making system that automatically and continuously freezes the ozone-dissolved water produced in the first or second embodiment. Regarding equipment. That is, in FIG. 4, the produced ozone-dissolved water is temporarily stored in a closed tank 31 connected via a solenoid valve 30. This sealed tank 31 is connected to the ice maker 33 through a water supply port 32 opened at the bottom thereof, so that a fixed amount of ozone-dissolved water is constantly supplied to the ice maker 33. A level switch 34 is installed in the sealed tank 31, and when the amount of water in the tank becomes low, the switch is turned on to open the solenoid valve 30 and transfer the ozone-dissolved water to the sealed tank 3.
Send it inside 1. When the amount of water reaches an appropriate level, the switch is turned off and the solenoid valve 30 is closed. Furthermore, when the amount of water is fed to the point where it is about to overflow, the excess water enters an overflow pipe 35 having an opening near the top of the closed tank 31, joins with a drain pipe 38 to be described later, and is discharged. The ice maker 33 is connected to a stocker 36 to store ice made from ozone-dissolved water. This stocker 36 also has a level switch 3.
7 is installed, and when the amount of ice exceeds a certain amount, the switch is turned on to close the connected solenoid valve 30, and when the amount of ice is below a certain amount, the switch is turned off and the solenoid valve 30 is opened. 38 is a drain pipe,
This is a pipe that discharges the ice-melting power inside the stocker 36.
