Abstract

PURPOSE:To realize high concn. ozone solubility by mounting a treatment pipe provided with an ozone supply part, a magnetic treatment part and a stirring part in order from a raw water supply part to an ozone dissolved water discharge part. CONSTITUTION:An ozone supply part 3, a magnetic treatment part 4 and a stirring part 5 are provided to a treatment pipe 2 in order from a raw water supply part 2s to an ozone dissolved water discharge part 2e. The ozone supply part 3 is provided to a region where ozone O supplied from an ozone feeder 6 is injected in the high velocity water stream S in the treatment pipe 2 by utilizing the high pressure air E supplied from a high pressure air feeder 7. Ozone O is efficiently mixed with and dissolved in the water stream S under high pressure due to a high pressure air/ozone mixture OE. By providing the magnetic treatment part 4 on the downstream side of the ozone supply part 3, the magnetic treatment part largely contributes to the enhancement of magnetic treatment efficiency related to the mixing and dissolution of ozone O, in its turn, the mixing and dissolution of ozone O and a high ozone mixing and dissolving degree can be realized.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention applies ozone (O8) to a water stream flowing at high speed in a pipe.
This invention relates to an ozone water production device for injecting, mixing and dissolving ozone water.

[Conventional technology]

As this type of ozone water production device, for example, Japanese Patent Application Laid-Open No. 63
There is one as shown in Japanese Patent No.-200891.

This ozonated water production device had a maximum of 0.7
Compared to previous studies, it was only possible to achieve a solubility of about 3 ppm (ppm);
It was possible to achieve a very high concentration of ozone solubility (ozone injection amount: g/hr), and to achieve a reasonably excellent ozone treatment effect.

[Problem to be solved by the invention]

However, an ozone solubility of 5 ppm is not necessarily sufficient, and according to some research results, 6 ppm
Knowledge has been given that if an ozone solubility of pm or higher is obtained, the water treatment effect will be significantly improved.

Against this background, the present inventor has made various improvements and devises for an ozone water production device that can break the new solubility barrier of 6 ppm or more, and we have now reached the completion of these efforts. .

[Means to solve the problem]

Specifically, the ozone water production device according to the present invention includes an ozone supply section, an ozone supply section,
It is equipped with a processing tube provided with a magnetic processing section and a stirring section.

[For production]

One of the features of this ozone water production device is that the magnetic treatment section is provided downstream of the ozone supply section.

By installing the magnetic processing section downstream of the ozone supply section in this way, although the detailed mechanism is unknown, the magnetic processing efficiency for mixing and dissolving ozone was improved, and higher ozone mixing and solubility was achieved. It is something.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Fig. 1 shows an ozone water production apparatus according to the present invention.
In the main part of the treatment pipe 2, an ozone supply part 3, a magnetic treatment part 4, and a stirring part 5 are provided in order from the source water supply side 2S to the dissolved water discharge side 2e, that is, from upstream to downstream. ing.

The processing tube 2 is U-shaped, which is also one of the features of this device, and this allows the entire device to be miniaturized.

The ozone supply unit 3 is a part that injects ozone (ozone gas) O supplied from the ozone supply machine 6 into the high-speed water flow S in the processing tube 2 using high pressure air E supplied from the high pressure air supply machine 7. be.

Specifically, as shown in Fig. 3, the tip of the high-pressure air supply pipe 8 is bent into an L-shape to form a jetting section 8V, and this jetting section 8■ directs the jetting port 8h at the tip downstream. Water flow S
Further, an ozone supply pipe 9 is connected so as to be perpendicular to this ejection part 8V. In other words, the ozone O supplied through the ozone supply pipe 9 is mixed into the high pressure air E by the negative pressure generated by the high pressure air E flowing at high speed through the ejection part 8V, and the high pressure air ozone mixture O is mixed with the ozone O supplied through the ozone supply pipe 9.
E, and the ozone ○ is efficiently mixed and dissolved in the water stream S using the high pressure generated by this high-pressure air-ozone mixture OE.

In this way, when ozone O is supplied as a high-pressure air ozone mixture OE, this high-pressure air ozone mixture OE acts like an air hammer, so that the slime in the water pipe to which this ozone water production device 1 is connected is removed. , very useful for removing rust galls, etc.

What is shown by imaginary lines in FIGS. 1 and 3 is a branch pipe 8b for branching and introducing the water flow S flowing through the processing tube 2 to form a branch flow Sd. That is, in place of the above-mentioned high-pressure air E, a divided flow Sd is flowed into the high-pressure air supply pipe 8, and ozone O is supplied into the high-speed water flow S by the negative pressure caused by this divided flow Sd. In this case, the above-mentioned " Since it does not have the "air hammer effect," ozone is mainly used for sterilization. In addition, high pressure air E and branch flow Sd
The appropriate use is made by operating valves V1 and V2.

According to such a mixing/dissolving structure, ozone O can be injected into the water stream S at high pressure, and the mixing/dissolving efficiency can be greatly increased, and there is no need to generate high pressure in the ozone supply device 6. Maintenance of ozone supply machine 6
This has the advantage of being easier to manage. In other words, if the ozone supply device 6 is equipped with a complex mechanism such as a pump for generating high pressure, the strong oxidizing power of ozone will quickly damage these components, making maintenance and management difficult. However, by eliminating the need for such pumps for generating high pressure, maintenance and management of the ozone supply device 6 can be facilitated.

One of the features of this ozonated water production apparatus l is that the magnetic processing section 4 is provided downstream of the ozone supply section 3.Although the detailed mechanism is unknown, in this way the magnetic processing section 4 is installed downstream of the ozone supply section 3. Providing it downstream of No. 3 greatly contributes to improving the magnetic processing efficiency for mixing and dissolving ozone O, and by extension, to mixing and dissolving ozone O.

As shown in FIG.
2.12, fixed with -゛-゛, each magnetic bar 1
1.11, "- is parallel to the water flow S.

As shown in FIG. 5, the stirring section 5 includes a plurality of semicircular fins 13, 13, -
・The fins 13 and 13 are attached at regular intervals so that the angles are shifted by 90 degrees, and a spiral flow path is formed by these semicircular fins 13 and 13.
Stirring is achieved by passing the water stream S through this spiral channel.

The maximum solubility of ozone achieved by such ozone water production apparatus 1 is 18 g at a treatment rate of 5 tons/hr.
The ozone injection amount was 8.6 ppm.

〔Effect of the invention〕

As explained above, the ozone water production device according to the present invention includes a processing pipe in which an ozone supply section, a magnetic processing section, and a stirring section are provided in order from the source water supply side to the dissolved water discharge side. By providing the magnetic processing section downstream of the ozone supply section, there is an effect that higher mixing and solubility of ozone can be achieved than in conventional systems.
