2. Description of the Related Art As is well known, ozone-melted water is often used to prevent contamination of living water and the generation of offensive odors. For this reason, various ozone-melting devices have been proposed. .

[0003] For example, there is a proposal to jet water into an ozone atmosphere generated by an ultraviolet lamp, mix ozone with the water, and recover the ozone. There are advantages available.

However, in the above-mentioned conventional proposal, most of the ozone is mixed only with water and is not melted. Therefore, there is a disadvantage that ozone is easily released from the generated ozone molten water. is there.

Therefore, conventionally, means for obtaining molten ozone by means of a device equipped with large stirring blades, or means for mixing once generated ozone molten water again with a jet jet have been adopted. is the current situation.

[0006]

However, in the above-mentioned conventional proposals, large power is required to operate the apparatus by any means, and as a result, the installation space must be widened. In addition, there was a problem that the running cost increased and the cost increased.

[0007] Further, generally, the rate at which ozone can be dissolved in water without using power is about 10%, and it is said that if the melting rate is 15% or more, breakthrough is achieved. Is also the current situation.

The present invention has been made in view of the above situation, and an object of the present invention is to provide a simple facility for dissolving ozone-melted water having a high melting degree of 15% or more without particularly requiring power. An object of the present invention is to provide an ozone melting method and an apparatus which can be obtained at low cost.

[0009]

In order to achieve the above object, an ozone melting method according to the present invention comprises: supplying ozone mixed water from below a water tank body having a multi-stage mesh body disposed therein; Ozone bubbles not mixed with water in
After accumulating under the mesh body arranged at the upper part of the stage and gradually growing it into large bubbles, the bubbles grown to a certain size are aerated, and ozone is pumped to the upper stage to thereby feed the upper stage. The step of melting the ozone aerated in the ozone water is repeated in multiple stages. Further, in the present invention, in order to realize the above method, an ozone melting device, a water tank main body having a lower end connected to an ozone mixed water supply pipe, and an upper end connected to a discharge pipe, And a mesh body extended in multiple stages in the water tank main body, and ozone bubbles not mixed with water in the lower stage are gradually collected under the mesh body arranged at the upper part of the stage. The bubbles grown to a certain size by growing into large bubbles are aerated under the mesh body of the stage and ozone is pumped to the upper stage to melt the ozone aerated in the ozone water of the upper stage. Is repeated in multiple stages.

Therefore, according to the present invention, when the ozone-mixed water is supplied from the outside into the water tank main body through a water supply pipe connected to the lower end of the water tank main body, the ozone-mixed water is disposed at the lowest stage of the water tank main body. Ozone gas bubbles released from the ozone mixed water are temporarily stored below the provided mesh body.

When the stored state of the air bubbles is continued, the ozone gas gradually stored on the lower surface side of the ozone gas aerator is aerated, and the ozone gas is transmitted through the ozone gas aerator and stored in the upper stage by the aeration. Melts with water. The aeration is repeated a plurality of times before reaching the top of the water tank body, whereby the ozone gas is gradually eroded into the water, and finally, ozone molten water in which most of the ozone gas is melted is obtained.

On the other hand, the discharge pipe 12 is connected to the upper end of the water tank main body 1 through a bracket 12a, and discharges the ozone molten water generated in the water tank main body 1 to the outside of the water tank main body 1.

The ozone gas aeration means 2 is arranged horizontally, for example, about 10 steps along the longitudinal direction of the inner peripheral wall 1a of the water tank main body 1. As shown in FIG.
It comprises a pair of upper and lower frame-shaped brackets 21 and 21 attached to the inner peripheral wall 1a, and a mesh body 22 held by the frame-shaped brackets 21 and 21.

The frame-shaped bracket 21 is formed in an angle shape. One of the flange portions 21a is fixed to the inner peripheral wall 1a of the water tank main body 1, and the other flange portion 21b has a mesh body 22 sandwiched therebetween. It is arranged in a state of being stretched across the water flow. Of course, the flange part 2
An appropriate sealing member may be interposed between the inner peripheral wall 1a of the tank body 1 and the inner peripheral wall 1a.
