Abstract

PURPOSE:To freely enhance an ozone dissolving ratio, by mounting a mixing chamber for contacting and mixing water with ozone and by providing a grinding means for finely pulverizing water in the mixing chamber. CONSTITUTION:The water sent into a mixing chamber 7 under pressure by a pressure feed means 4 is injected from a large number of the nozzles arranged to the entire inner wall surface of the mixing chamber 7 and finely pulverized to be formed into mist to fill the mixing chamber 7. Ozone is present in the mixing chamber 7 and violently collides with fine water particles fed in the mixing chamber 7 under pressure to be brought into contact with a mist of water many-sidedly at extremely high density. As a result, the fine water particles grow to water droplets having a large amount of ozone dissolved therein to be accumulated on the bottom part of the mixing chamber 7 and supplied as high concn. ozone dissolved water from an outlet 9. By this method, an ozone dissolving ratio can be freely adjusted.

[Detailed Description of the Invention] Industrial Application Field] The present invention is directed to the supply of sterile water used in food processing, thawing, etc., the deodorization and sterilization of drinking water, the purification of cooling water, etc. This invention relates to a device for dissolving ozone. 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 is difficult to freely adjust the ozone dissolution rate. Therefore, it has been difficult to obtain ozone-dissolved water suitable for various uses.

[Purpose of the Invention] An object of the present invention is to solve the above-mentioned problems, and to 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 connected to a mixing chamber 7 via a water volume adjustment valve 5 and an Affi meter 6. The pressure feeding means 4 sucks water from the water source 1 and sends the water into the mixing chamber 7. 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 a pressure feeding means 11. It is connected to an ozonizer 14 via a valve 12 and a filter 13, and is further connected to the mixing chamber 7 via an ozone 1m8 regulating valve 15.
It is tied to 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, and the labor and cost of producing ozone from air can be saved, and ozone can be easily produced manually. The effort and cost of specially providing the pressure feeding means 11 can also be saved. Furthermore, there are various advantages such as being able to prevent the generation of nitrogen oxides and eliminating toxicity when producing ozone from air. 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 employed. After dust is removed from the ozone source 10 through a filter, a portion of the ozone source 1O is converted into ozone by an ozonizer 14 and sent into the mixing chamber 7 together with the remaining non-ozonized oxygen. The pumping means 11 for this feeding is a compressive force attached to the ozone source IO.

Next, FIG. 2 shows an embodiment of a crushing means for turning water into fine particles. The crushing means 8 is composed of a large number of nozzles arranged on the entire wall surface of the mixing chamber 7, and in FIGS. When the mixture is mixed, it is ejected from a large number of nozzles arranged on the entire wall surface of the mixing chamber 7, and the mixing chamber 7 is filled with the atomized atomized particles. On the other hand, the oil 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. Ozoinizer 14
, or the power factor of the crushing means 8 or the ozone amount adjusting valve 15
By adjusting the water ffl adjustment valve 5, it is possible to adjust the ozone dissolution rate 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 the water in which ozone has already been dissolved is re-ozone-dissolved. By mixing with ozone, the ozone concentration is increased.

In this case, it is also possible to simply circulate the ozone-dissolved water produced in the above-mentioned first example within the same production equipment, but in the second embodiment described here, as shown in FIG. The water source l is temporarily stored in a water tank 20 via a valve 2 and a filter 3. Water tank 2
The mixing chamber 7 is installed together with the crushing means 8 in the mixing chamber 7, and an underwater pipe 21 is connected to the outlet 9 of the mixing chamber 7, and the underwater pipe 21 extends to the bottom of the water tank 20. He was released at the same location. That is, the ozone-dissolved water coming out of the outlet 9 is led to the bottom of the water storage tank 20 by the underwater pipe 2I. The water tanks 20 are communicated with each other by a water level adjuster 22 installed nearby and a plurality of communication pipes 23 provided above and below the side walls of the water tanks. 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 to open and close the valve 2 at each stage of the water level. Note that the valve 2 here is a solenoid valve.

Further, an overflow pipe 29 is drawn out from near the upper edge of the water level adjustment tank 22 so that excess water can be discharged.

When the water comes out from the drain port 26 opened at the lowest water position of the water level adjustment tank 22, a cock 2 installed at the end of the T-shaped pipe
7 or if the water tap 28 is closed, the pressure feeding means 4
It is designed to be attracted to. 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 cock 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 an infinite number of times, so it is possible to increase the ozone dissolution rate.

A level switch 34 is installed in the closed tank 31, and when the amount of water in the tank becomes low, the switch is turned on to open the electromagnetic valve 30 and send ozone-dissolved water into the closed tank 31.

Then, when the water level reaches the appropriate level, the switch is turned off and the solenoid valve 30
Close. 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 water made from ozone-dissolved water. A level switch 37 is also installed in this stocker 36, and when the ice exceeds a certain amount, it turns on and closes the connected solenoid valve 30, and when the ice falls below a certain amount, it turns off and opens the solenoid valve 3G. is being used. 38 is a drain pipe, which is a pipe for discharging the ice-melting water in the stocker 36.
