In addition, coagulant injection devices 13 and 14, automatic chlorine injection devices 15 and 16, and valves 17 and 18 are used.
[0004]
The circulating water discharged from the circulating water discharge port 3 of the circulating water utilization facility 2 flows into the circulating water recovery tank 5, and circulates into the circulating water utilization facility 2 via the circulating water hair catcher 7 and the circulating water filtering device 11. On the way, the coagulant for dirt coagulation is injected by the coagulant injection device 13, the coagulated dirt is removed by the circulating water filtration device 11, and sterilizing chlorine is injected by the automatic chlorine injection device 15.
This circulation is performed by the circulating water pump 9 and the valve 17.
[0005]

In these water circulation systems, rust generated in each device and piping, scale due to the deposition of inorganic substances in water on each device and piping is generated, algae is generated, slime which is an adhesive substance generated by bacteria in the water. In addition, sterilization or removal of bacteria inhabiting in algae or slime (particularly Legionella spp., Which may cause severe pneumonia) has become a major issue.
[0009]
In a water circulation system in which water directly contacts a human body, such as a pool or a bath facility, the water is conventionally used as a filtering agent for a circulating water filtration device 9 and an overflow water filtration device 12 for purifying mineral substances such as sand and gravel, plants, and the like. In addition to using a fibrous or porous synthetic resin, a coagulant for soil coagulation is injected by a coagulant injection device 14 and chlorine for sterilization is injected by an automatic chlorine injection device 16.
On the other hand, it is considered that a cooling system using a cooling tower does not come into direct contact with water, and treatment using a chemical is employed.
[0010]
Recently, attention has been paid to a relaxing effect and a refreshing effect by negative ions. This negative ion is an oxygen ion O ₂ ⁻ surrounded by a plurality of water molecules (H ₂ O), and is expressed as [O ₂ ⁻ (H ₂ O) _n ].
At the same time as the negative ion, a positive ion in which the hydrogen ion H ⁺ is surrounded by a plurality of water molecules (H ₂ O) is generated in the same amount, and this positive ion is expressed as [H ⁺ (H ₂ O) _m ]. Is done.
An equal amount of these negative and positive ions are produced, and the mixture is called plasma cluster ions.
[0011]
It has been confirmed that negative ions have not only a relaxing effect and a refreshing effect but also a favorable effect on hair.
Furthermore, in addition to the favorable effect on the human body, it has been confirmed that the discoloration of vegetables in the refrigerator is suppressed and the amount of water evaporated is reduced.
It is also considered desirable that the cluster of water molecules accompanying the negative ion be as small as possible.
[0012]
In the case of plasma cluster ions, since the structure of protein hemagglutinin on the surface of the influenza virus is changed, the virus stops functioning and is inactivated, thereby confirming the effect of preventing influenza infection. (See page 63 of the Nikkei Electronics October 21, 2002 issue)
In addition, the effect of suppressing the occurrence of mold has been confirmed.
[0013]
Conventionally, there are methods of generating these negative ions and positive ions by discharge and by collision of water droplets.The simplest method is to use discharge. Occasionally, the countermeasures against the off-flavor and strong oxidizing action of ozone are issues.
[0014]
Mineral and positive ions can also be generated by using minerals, such as tourmaline, tourmaline, amphibolite, and barite, which are natural, and ceramic balls are also used as artificial ones. Used.
[0015]
Summary of the Invention
In view of such circumstances, the present application provides an invention of a water purification material, a water purification device, and a water purification system that generate negative ions, positive ions, and plasma cluster ions.
[0016]
The water purifying material according to the present invention is formed by kneading a ceramic material with a plastic material having a small specific gravity into a shape having a large surface area, a large porosity, and no entanglement with each other.
In the water purifying material according to the present invention, the kneaded ceramic powder generates negative ions, positive ions, and plasma cluster ions, and makes water molecule clusters fine.
[0017]
The water purifying material sealed in the water purifying apparatus according to the present invention is sealed in a water-permeable container made of a corrosion-resistant metal or the like at about 70% of its volume. The shape of the container is appropriately configured according to the place of use.
The water purification material enclosed in the water purification device according to the present invention by about 70% of the volume of the container is agitated by the flow of the water to be purified passing through the water purification device, makes sufficient contact with the water to be purified, and Functions are fully demonstrated.
[0018]
The water purification system according to the present invention is configured by disposing the water purification device at an appropriate position in the water purification system to which the water purification device is applied.
In the water purification system according to the present invention, since the water purification device is disposed at an appropriate position, optimal water purification is performed.
[0019]
【Example】
Hereinafter, embodiments of the invention according to the present application will be described.
FIG. 3 shows an example of the shape of the water purifying material 20 according to the present invention. In this water purifying material, 10% ± 5% of calcined ceramic powder is mixed into polyethylene or ethylene / α-olefin copolymer having a specific gravity smaller than 1. The specific gravity is about 1.01 ± 2%. The specific gravity can be appropriately adjusted to a necessary value around 1.4 depending on the mixing ratio of the ceramic powder.
[0020]
This water purifying material 20 can be obtained by the following method.
(1) The ceramics-kneaded plastics are formed into a cylindrical shape.
{Circle around (2)} A ceramic kneaded plastic cylinder is thinly and spirally cut along its radius to obtain a spiral body.
{Circle around (3)} The obtained spiral is formed into a saddle shape along the central axis of the cylinder.
{Circle around (4)} The spiral body formed in a saddle shape is twisted in the winding direction or in the opposite direction for each rotation of the spiral.
[0021]
The water purifying material 20 of this shape has a large surface area and therefore has a sufficiently large contact area with the water to be purified, so that the water to be purified and the water purifying material 20 can make good contact with each other. The water to be purified comes into sufficient contact with the surface of the water purification material 20 because it has a rate. Further, since the end of the water purification material 20 is not exposed on the surface, the water purification materials 20 do not become entangled with each other.
As a result, since the water to be purified and the water purification material 20 always make good contact, negative ions, positive ions, and plasma cluster ions are generated, and the water molecule cluster, which tends to become large, is also subdivided. .
[0022]
The cylinder used for cutting the helical body has a diameter of about 10 to 35 mm, but the shape may be a polygonal pillar other than the cylinder. Further, the cylinder kneaded with ceramics is hard and slippery, so that it is not easy to grip and rotate the end to rotate it into a spiral shape. However, when a polygonal column is employed as the shape, the cutting becomes easy.
[0023]
FIG. 4 shows an example of the water purification material storage container 21 according to the present invention.
The water purifying material storage container 21 shown in FIG. 4 is made of a corrosion-resistant punching metal such as stainless steel at both ends of a cylinder 22 made of a corrosion-resistant punching metal such as stainless steel. The water purifying material 20 is housed in a cylindrical container having a bottom 23 and a lid 24.
The size 25 of the perforated metal used is such a size that the water purification material 20 cannot pass through, and the water purification material 20 is accommodated in about 70% of the volume of the water purification material storage container 21.
[0024]
FIG. 5 shows an example of a water purification device configured to house the cylindrical water purification material storage container 21 shown in FIG.
The water purification device 26 shown in this figure is provided with a non-purified water inlet 28 at the lower side of a cylindrical main body 27 and a purified water outlet 29 at the upper side. The water purification device 26 is the circulating water filtration device 11 and the overflow water filtration device 12 in this embodiment.
[0025]
The arrangement relationship between the inflow port 28 and the outflow port 29 is also possible in the reverse position, and it is also possible to arrange them not on the side surface but on the upper and lower bottom portions 30 and the lid portion 31. It is appropriately selected.
[0026]
The specific gravity of the water purification material 20 stored in the water purification material storage container 21 stored in the water purification device 26 is about 1.10 ± 2%, which is larger than water. Stagnated at the bottom.
Non-purified water flows in from the non-purified water inlet 28 of the water purification device 26 in such a state, and purified water flows out from the purified water outlet 29. The inflowing water to be purified flows upward from the bottom inside the water purification device 26, and together with this water, the water purification material 20 is flushed toward the upper part of the water purification material storage container 21. Is stirred inside the water purification material storage container 21.
[0027]
As described above, the water purification material 20 has a sufficiently large contact area with the water to be purified and is well stirred with the water to be purified because it is stirred in the water to be purified. Ions and plasma cluster ions are generated, and these ions cause fragmentation of the water molecule cluster. As a result, the surface active effect is activated, slime and algae causing bacteria are removed, and good purified water is obtained. At the same time, generation of rust and adhesion of scale are suppressed. At that time, pollutants in the water to be purified are adsorbed by the water purification material 20 and removed.
[0028]
Chlorine is injected into the obtained purified water by the automatic chlorine injectors 15 and 16 so as to conform to the regulation that regulates the residual chlorine concentration, and finally flows to a circulating water utilization facility such as a pool or a bathtub.
[0029]
As another method for forming the water purification material 20, there is a method disclosed in Japanese Patent Application Laid-Open No. 7-75712.
[0030]
The outer shape of the water purifying material storage container 21 according to the present invention is, in addition to the cylindrical shape shown in FIG. 4, a rectangular parallelepiped shape shown in FIG. 6A, a conical shape shown in FIG. 6B, and a pyramid shown in FIG. The shape can be appropriately selected according to the shape of the water purification device that stores the water purification material storage container 21, such as the shape of a truncated cone shown in (d) or the shape of a truncated pyramid shown in (e).
[0031]
In addition, the water purifying material storage container 21 is provided separately from the circulating water collecting tank 5, the overflow water collecting tank 6, the circulating water filtering device 11, and the overflow water filtering device 12 as an independent water purifying device in the circulating water path. It is also possible.
Further, the water purifying material storage container 21 can be disposed in the wall surface of the circulating water utilization facility 2, the circulating water drain port 3, or the overflow water collecting groove 4 without being stored in the water purifying device 26.
[0032]
