[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pool water purification device which is compact and easy to install.

[0002]

2. Description of the Related Art With the recent boom in fitness, more and more people perform swimming as a whole-body exercise suitable for promoting health and relieving stress, and more and more people are familiar with the pool regardless of age or sex.

Accordingly, in order to enjoy swimming more safely and hygienically, there is an increasing interest in the hygiene condition of the pool, especially the water quality, and the demand for the purification device that determines the water quality of the pool is becoming more and more severe. The performance is increasing and the size is increasing accordingly.

The pool water purifying device is generally a filtering device for removing impurities such as dust and hair contained in pool water,
It has an adsorption purification device, a sterilizing device for sterilizing pool water, etc., and a device for supplying a filter aid to the filtering device, if necessary, and a warming means for pool water, etc. The pool water is purified by being circulated between the purification device and the pool, and is kept hygienic.

[0005]

By the way, when a new pool is constructed, there is a trade-off with other works such as the construction of the pool itself. It is desirable that it can be done in a short period of time. This is also the case when replacing the existing pool purification equipment with a new equipment, especially in the case of hot water pools that are used all year round, which is also important for shortening the so-called closing time. .

However, since a pool water purifying device, especially a high performance one having excellent purifying ability is large in size, there are various difficulties such as the need for a large conveying means to convey such a device. Accompany. Moreover, the pool water purification device is usually installed in a relatively narrow and restricted place, and as described above, there are many types of filtration devices, various sterilization devices, adsorption devices, etc. Since it has components, the piping connecting these components becomes complicated. Moreover, at the installation site, the use of machines and tools such as cranes and hoists is restricted. Therefore, the installation work of the purification device at the installation site has become time-consuming and difficult.

An object of the present invention is to solve the above-mentioned problems of the prior art, and preferably satisfies the ability required for a pool water purification device such as filtration and sterilization of impurities, and is compact in installation work. To provide an easy pool water purifying device.

A cylindrical porous ceramic filter (hereinafter referred to as a ceramic filter) 36 is provided inside the first housing 30. The pool water is filtered from the outside of the ceramic filter 36 by passing through the wall. Then, fine impurities such as oil released from the human body are removed. Purification device of the first aspect of the present invention includes a cylindrical incorporating such cylindrical porous ceramic filter 36
It is built adsorption-purifying agent to be described later on the inner side of the microfiltration tank
That the cylindrical suction cleaning tank and / or the inner sterilization means
The basic configuration is that the cylindrical sterilization tanks to be stored are arranged adjacent to each other.

The ceramic filter 36 applied to the purification apparatus 14 of the illustrated example has a three-dimensionally extremely fine filtration space which is preferable for filtration of a pool, especially a hot water pool, and filtration by a conventional filter is impossible. Organic matter such as oil released from the human body can also be suitably filtered.

A second housing 38 is arranged inside the first housing 30. The second housing 38 forms a flow path for the pool water that has passed through the ceramic filter 36, has a cylindrical shape, and discharge pipes 40, 40 are formed below the outer wall. In the second housing 38, the inside of the wall forming the cylinder serves as the flow path of the pool water. Therefore, the portion of the second housing 38 that faces the ceramic filter 36 is open, and the pool water that has passed through the ceramic filter 36 can flow in. Here, the first and the second which are cylindrically adjacent to each other
Housings 30 and 38 include ceramic filter 36.
A cylindrical microfiltration tank containing the above is constructed.

A third housing 42 is arranged inside the second housing 38. The third housing 42 has a cylindrical shape in which the inside of a wall forming a cylinder serves as a flow path of pool water, as in the case of the second housing 38 described above, and the inner wall upper end portion is formed from a fourth housing described later. There is an inlet 44 through which the pool water flows, and below the outer wall, a discharge pipe 4 connected to a return line 28 to the pool 12.

Make up.

A fifth housing 56 is arranged inside the fourth housing 50. Like the second housing 38 described above, the fifth housing 56 has a cylindrical shape in which the inside of the wall forming a cylinder serves as a flow path for pool water, and the upper end of the inner wall has an inlet through which pool water flows. The mouth 58 is formed, and discharge pipes 60, 60 are formed below the outer wall.

A sixth housing 62 is arranged inside the fifth housing 56. The sixth housing 62 has a cylindrical shape having an air inlet 63 at the lower end, a lamp unit 64 in which an ultraviolet lamp and an ozone lamp are combined, and an upper surface through which water does not pass. An air bleeding filter 65 that allows air to pass therethrough is provided. That is, the sixth housing 62 serves as a sterilizing means of the purifying device 14 of the present invention, and by introducing air from the air introducing port 63 as necessary, water is sufficiently bubbled and stirred, and ozone is generated. Then, the pool water is sterilized by the ozone and the ultraviolet rays.

Introducing pipes 66, 66 are formed below the outer wall of the sixth housing 62. Where each other is a circle
Cylindrically adjacent fifth and sixth housings 56 and 6
2 is an ultraviolet sterilization lamp and sterilization that constitute sterilization means
Cylindrical lamp unit having an ozone lamp for generating ozone
A cylindrical sterilization tank containing the knit 64 is constructed.

The purifier 14 of the illustrated example, which is formed by combining by inserting the second to sixth housing on the inner side of the first housing 30, thereby, a first purification of the present invention on the inner side of the cylindrical ceramic filter 36 is a basic configuration of the device, the activated carbon 48 is adsorbed purifying means
And the lamp unit 64 which is a sterilizing means is arranged. With such a configuration, the purification device according to the first aspect of the present invention can be made extremely compact despite having the adsorption purification means and / or the sterilization means. Moreover, since these can be integrated into a unit-like structure, this unit can be installed on-site after manufacturing, and installation work can be facilitated.

The purification apparatus 1 of the first embodiment of the present invention in the illustrated example
Although 4 is composed of 6 housings, the present invention is not limited to this and may be composed of more or less housings. Further, each housing may be formed into a cassette, and the purifying device may be configured by an arbitrary combination. Further, the purifying device 14 in the illustrated example has both the adsorption purifying means and the sterilizing means as a preferred embodiment, but in the present invention, either one may be provided as described above.

Further, the purifying device of the present invention is not limited to the one constituted by one such purifying device, but may be constituted by combining a plurality of purifying devices as a unit. Is.

The purifying action of the pool water by the purifying device 14 will be described below. Although omitted for simplification of the drawings and for clarity of explanation, it goes without saying that the respective introduction pipes and discharge pipes are connected by necessary pipes.

The pool water from which large impurities such as hair and dust have been removed by the pre-filter 24 flows into the first housing 30 from the introduction pipe 34 through the inflow line 26 and passes through the wall from the outside of the ceramic filter 36. Then, fine impurities such as oil discharged from the human body are removed, and the fine particles flow into the second housing 38 and flow out of the housing through the discharge pipe 40.

Next, the pool water flows into the sixth housing 62 through the introduction pipe 66, and is sterilized by ozone and ultraviolet rays generated by the lamp unit 64 while flowing upward.

The sterilized pool water flows into the fifth housing 56 through the introduction port 58, descends and flows out of the housing through the discharge pipe 60, and the fourth housing 5 through the introduction pipe 52.
0 and rises, and the outlet 54 of the fourth housing 50
From the (inlet 44 of the third housing) to the third housing 4
Inflow to 2.

The pool water flowing into the third housing 42 descends and passes through the activated carbon 48 (and / or zeolite), and bacteria such as ozone and ultraviolet rays decomposed by the activated carbon 48 are removed by adsorption and discharged. It flows into the return line 28 from the pipe 46 and is returned to the pool 12.

The ceramic filter 36 applied to the purifying apparatus 14 of the illustrated example has very fine pores that can filter oil and the like discharged from the human body. Therefore,
If the ceramic filter 36 is directly used for filtration, the holes may be clogged and cleaning may become very difficult. Therefore, in the purification device 14 of the present invention, fibrous filter aids such as cellulose, pulp fiber, asbestos, powdery filter aids such as diatomaceous earth and lime,
It is preferable to form (precoat) this filter aid layer on the outer surface of the ceramic filter 36 by using various filter aids such as the above, and perform filtration using this aid layer.

Further, in the purifying device 14 of the present invention,
In addition to such a filter aid layer, a layer made of silica gel that selectively adsorbs proteins (hereinafter referred to as a silica layer) may be formed in order to further improve the purification effect of pool water.

As the silica gel that selectively adsorbs proteins, various known ones can be applied, and silica hydrogel is particularly preferred. Silica hydrogel is one in which several millimicron SiO ₂ molecules form one macromolecule in a three-dimensional structure and have a uniform pore diameter, a large pore volume, and a surface area. It has a network structure of silanol groups.

Silica hydrogels, especially those having a pore size of 80 to 1
By applying 00Å silica hydrogel to the adsorption purification means together with activated carbon, proteins and the like released from the human body can be suitably removed from the pool water.

As such a silica hydrogel, specifically, Brightsolve A-100 (manufactured by Asahi Glass Co., Ltd.) and the like are preferably exemplified.

The purification system 10 shown in FIG. 1 has a supply device 18 for such a filter aid and silica gel as a preferred embodiment.

The supplying device 18 supplies the powdery filter aid and the fibrous filter aid as the filter aid, and further the silica gel forming the silica layer to the purifying device 14, specifically to the outer wall of the ceramic filter 36. In the illustrated example, a so-called slurry pump 67 capable of liquid-sending a slurry-like material, a tank 68 for filling a mixture of powdery filter aid and water, a mixture of a fibrous filter aid and water are filled. And a supply line 72 for connecting the supply device 18 to the inflow line 26.

When forming each such filter aid layer, the line corresponding to the filter aid layer to be formed is opened, and the slurry pump 67 supplies the required amount of the filter aid mixture into the purification device 14. Then, after the slurry pump 67 is stopped and the valve is closed, the pump 22 may be driven to circulate in the same manner as when filtering water.

In the purifying apparatus 14 of the present invention, the order of forming the filter aid layer and the silica layer formed on the ceramic filter 36 is not particularly limited, and the silica layer is formed on the fibrous filter aid layer and the upper layer thereof is formed. A powdery filter aid layer may be formed in the above, or a configuration in which the fibrous filter aid layer and the powdery filter aid layer are reversed, or another configuration may be used. Further, each layer is not limited to those formed one by one, at least one of the layers may be formed in multiple layers,
All layers may be formed in multiple layers.

[0048] In the purification system of the illustrated example powdered and each filter aid fibrous (more silica gel)
However, the present invention is not limited to this, and only one tank is provided (one tank is provided) and a predetermined amount of one kind of filter aid is used. Put it in a tank and mix with water, and slurry slurry 6
In step 7 , the filter aid layer is transported to the purifying device 14 to form one layer, and then another filter aid (silica gel) is added to the tank to similarly form an upper filter aid layer. You may repeat.

The filtering method using such a filter aid layer is described in detail in JP-A-63-143917.

Further, the ceramic filter 36 applied to the purifying device 14 has very fine pores three-dimensionally, and if it is applied to purified water as it is, it will be clogged immediately, and in extreme cases. Would render the expensive ceramic filter unusable. Therefore, in the purification system 10 of the illustrated example, the filter aid layer is formed on the outer cylindrical portion of the ceramic filter 36 as described above to prevent the ceramic filter 36 from being clogged and to backwash the ceramic filter 36. It has a backwash device 16 for performing washing.

The backwash device 16 has a water storage tank 74, a pump 76, and a jet water flow generator 78, and the backwash line 80 has a drain pipe 40 of the second housing 38.
Is connected to the purifying device 14.

To backwash the ceramic filter 36, the water in the water storage tank 74 is transported at high speed by the pump 76, and this water is made into a jet water flow by the jet water flow generator 78.
This is performed by flowing into the second housing 38 through the backwash line 80 and the discharge pipe 40 and jetting a jet water flow from the inner wall of the ceramic filter 36. As a result, the filter aid, dust, and the like on the outer wall of the ceramic filter 36 are removed.

Such backwash cleaning is disclosed in detail in Japanese Patent Application No. 2-35029 filed by the present applicant.

FIG. 4 conceptually shows a pool water purification system 100 to which the purification device of the third aspect of the present invention is applied.

Pool water purification system 10 shown in FIG.
0 applies the purifying device 102 instead of the purifying device 14,
And, except that it has a backwashing device for the ultrafiltration means arranged in the purifying device 102, it is basically the same as the above-mentioned pool water purifying system, and therefore, the same members are denoted by the same reference numerals and detailed description thereof is given. Is omitted.

The purifying apparatus according to the second aspect of the present invention is
Since the pool water purification system 100 shown in FIG. 4 does not have a backwashing device of the ultrafiltration means, the description will be given together with the purification device 102 of the third aspect.

The purifying apparatus 102 applied to the third (second) aspect of the present invention is the purifying apparatus 14 described above with the addition of ultrafiltration means.

FIG. 5 shows a schematic sectional view of the purifying device 102.

The purifying device 102 has a structure in which cylindrical housings are combined in the same manner as the purifying device 14 described above, and the seventh housing 106 and the fifth housing 56 are provided between the fourth housing 50 and the fifth housing 56. 4 of 8 housing 108, 9th housing 110 and 10th housing 112
One housing is further arranged to form a pool water ultrafiltration means and a backwash device for the ultrafiltration means.

That is, the pool water that has passed through the ceramic filter 36 in the above-mentioned purification device 14 then passes through the introduction pipe 66 and is sterilized by the lamp unit 64, but in the purification device 102, the ceramic filter 3
The pool water that has passed through 6 is subjected to ultrafiltration by the ultrafilter 114 and then sterilized by the lamp unit 64.

A more specific description will be given. First, the seventh housing 106 is arranged inside the fourth housing 50. The seventh housing 106 serves as a path for introducing the pool water into the ultrafilter 114, has a cylindrical shape in which the inside of the wall forming the cylinder serves as the flow path of the pool water, and the upper portion of the inner wall is 8 Pool Water Inlet 116 to Housing 108
Has become.

The eighth housing 108 is arranged inside the seventh housing 106. In the purification device 102 of the illustrated example, all the pool water introduced from the seventh housing 106 is not subjected to ultrafiltration, and a part of the pool water passes through the ultrafilter 114 without being ultrafiltered. 8 Downstream of the housing 108 as it is (hereinafter referred to as overflow). The eighth housing 108 serves as a pool water supply path to the ultrafilter 114 and a pool water drain path overflowing from the ultrafilter 114. Also, the eighth
In the housing 108, a pool water inlet 119 to the ultrafilter 114 and a closing portion 107 for introducing the pool water to the ultrafilter 114 are formed.

The discharge pipe 114 of the eighth housing 108 is connected to the inflow line 26. As shown in FIG. 6, the connecting portion between the discharge pipe 114 and the inflow line 26 has a configuration in which the introduction pipe 29 from the discharge pipe 114 is inserted into the jet venturi 27, and overflows from the ultrafilter 114. The pool water is drawn into the purification device 102 again together with the pool water by the flow of the pool water flowing into the purification device 102 from the pool 12 via the inflow line 26.

Further, the pool water purification system 1 in the illustrated example
In 00, the supply line 72 of the filter aid supply device 18 is branched and connected to the flow path of the overpoured pool water from the discharge pipe 114 to the inflow line 26, and the pool water is connected to the ceramic filter 36. In addition, a suitable amount of filter aid such as diatomaceous earth is supplied. With such a configuration, viruses and the like that pass through the ceramic filter 36 but can be separated from pool water by the ultrafilter 114 described later can be separated by the ceramic filter 36 together with diatomaceous earth. In addition to diatomaceous earth, various types of auxiliary agents such as cellulose, activated carbon, silica gel, and the like that form a fine powder emulsion can be applied as such an auxiliary agent.

The ninth housing 110 is disposed inside the eighth housing 108. The ninth housing 110 is
Holding the ultrafilter 114, and forms a water channel of the pool water ended ultrafiltration. Note that here,
7th, 8th and 9th housings 106, 108 and
110, or the seventh and ninth housings 106
And 110 are cylindrical limits containing the ultrafilter 114.
It constitutes an outer filtration tank.

Ultrafiltration means this ceramic filter 3
No. 6, which cannot be separated, is capable of separating viruses such as AIDS virus, influenza virus, Japanese encephalitis virus, hepatitis virus, etc., which are smaller than fungi, and the purification device 102 is limited to performing ultrafiltration. By having the outer filter 114, the pool water can be purified to a higher degree and the pool 12 can be kept cleaner.

The ultrafiltration means applied to the purifying device 102 of the present invention is not particularly limited as long as it has the above-mentioned characteristics (ability to separate viruses etc.), and various known ultrafiltration means can be used. Although any of them is applicable, in particular, an ultrafiltration means applying a cylindrical hollow fiber membrane capable of separating viruses and the like is preferably applied, and the ultrafilter 114 of the illustrated example is applied.
Has an annular shape in which a large number of hollow fiber membranes are arranged in the vertical direction in the figure.

That is, in the ultrafilter 114 of the illustrated example, basically, the hollow fiber membranes 114a oriented in the vertical direction are arranged in the same shape as the cylindrical shape of the ninth housing 110, and the ninth housing 110 is provided on the upper and lower end surfaces thereof. Top surface 114b having the same cross-sectional shape as
And the lower surface 114c is arranged,
Holes are formed in the upper and lower surfaces of the hollow fiber membrane 114a at the portions corresponding to the end openings. In such an ultrafilter 114, the pool water that has flowed into the ultrafilter 114 from the inlet 119 passes through the wall surface of the hollow fiber membrane 114a and flows into the hollow fiber membrane 114a, and then flows downstream to the lower surface. It is discharged more and is discharged downstream in the ninth housing 110. Here, since viruses and the like cannot pass through the wall surface of the hollow fiber membrane 114a, they are separated from the pool water.

The pool water from which viruses and the like have been removed by passing through the ultrafilter 114 flows into the sixth housing 62 through the discharge pipe 116 of the ninth housing 110.

The hollow fiber membrane 114a applied to the ultrafilter 114 of the present invention is not particularly limited, and various well-known hollow fiber membranes for ultrafiltration can be applied. The Kuraray UF filter (Kuraray Co., Ltd.) (Manufactured) and the like are preferably exemplified.

In the purification apparatus 102 of the illustrated example, the ultrafilter 114 is provided with an ultrasonic wave generator 118 for facilitating backwashing of the ultrafilter 114. The ultrasonic generator 118 is supported on the upper surface of the first housing 32, and is disposed so as to penetrate the upper surface 114b and the lower surface 114c of the ultrafilter 114.

When the ultrafilter 114 is continuously used, the hollow fiber membrane 114a is clogged with the separated virus or the like, and the processing capacity of the ultrafilter 114 is lowered. Therefore, in order to maintain a predetermined processing capacity, the ultrafilter 1
It is necessary to periodically clean 14 (hollow fiber membrane 114a), and the purification device 102 shown in FIG. 4 has a backwash cleaning means. The ultrasonic wave generator 118 improves the cleaning efficiency of the backwash by vibrating the hollow fiber membrane 114a by ultrasonic waves during the backwash. The backwashing of the ultrafilter 114 will be described in detail later.

There is no particular limitation on the ultrasonic wave generator applied to the present invention, and any known ultrasonic wave generator such as an ultrasonic diaphragm can be applied. Further, in the illustrated example, the two ultrasonic generators 118 are arranged in the ultrafilter 114, but the present invention is not limited to this, and the ultrafilter 11 is not limited to this.
4 may be arranged according to the size and capacity of the ultrasonic wave generator 4, the capacity of the ultrasonic generator 118, and the like.

The tenth housing 112 is disposed inside the ninth housing 110. Tenth housing 112
Forms an introduction path for washing water when backwashing the ultrafilter 114, and is connected to the ninth housing 110 at the upper part.

Next, the water purifying action of the purifying device 102 will be described. As described above, the purification device 102
Is the same as the purifying device 14 except that an ultrafiltration means is added to the purifying device 14.
A detailed description will be given on this point, and others will be omitted.

Pool water that has passed through the ceramic filter 36 in the same manner as in the purifying device 14 passes through the discharge pipe 40 of the second housing 38, the introduction pipe 120 and the seventh housing 10.
6 is flowed into. The pool water flowing in from the introduction pipe 120 rises in the seventh housing 106 and flows into the eighth housing 108 from the introduction port 116.

As described above, the closing portion 107 is formed in the eighth housing 108, whereby the pool water flows into the ultrafilter 114, but in the purification device 102 of the illustrated example, it is provided in the eighth housing 108. Not all of the inflowing pool water is used for ultrafiltration, but a part of it is used for ultrafiltration.
It is subjected to ultrafiltration by 14, and the rest overflows back into the eighth housing 108 and downstream.

The pool water flowing into the ultrafilter 114 is
Viruses and the like are removed through the side wall of the hollow fiber membrane 114a, the hollow fiber membrane 114a is discharged downstream to the outside of the ultrafilter 114, and the ninth housing 110 is discharged downstream to be discharged from the discharge pipe 116. From the introduction pipe 66 to the sixth housing 62
Flows into. The subsequent purifying action of the pool water is similar to that of the purifying device 12 described above.

On the other hand, the pool water that has not been subjected to ultrafiltration and has overflowed is discharged downstream from the eighth housing 108 through the discharge pipe 114 and from the pool 12 to the purifying device 10.
It is sucked into the inflow line 26 by the water flow of the pool water flowing into 2, and again flows into the purification device 102.

As described above, in the purification apparatus 102 of the illustrated example, the filter aid supply line 72 is branched and connected in the middle of the path from the discharge pipe 114 to the inflow line 26, and an appropriate amount of diatomaceous earth is used. Etc. are supplied. Therefore, viruses and the like contained in the overflowed pool water are adsorbed on the diatomaceous earth and the like, so that the viruses and the like can be separated by the ceramic filter 36.

As described above, the purification device 102 has a backwash device for the ultrafilter 114 (hollow fiber membrane).

This reverse line cleaning device basically comprises a wash water tank 122 for filling the wash water, a pump 124, a backwash line 126 (see FIG. 4), and the tenth housing 1 described above.
12, the ninth housing 110, and the eighth housing 10
8 and an ultrasonic wave generator 118, the hollow fiber membrane 114a of the ultrafilter 114 is vibrated by ultrasonic waves, and backwashing is performed.

In the purifying apparatus 102 of the illustrated example, when backwashing the ultrafilter 114, the wash water filled in the wash water tank 122 is pumped by the backwash line 1
Supply from 26. The backwash line 126 is connected to the discharge pipe 116 of the ninth housing 110 and the introduction pipe 128 of the tenth housing 112, and the wash water is on the upper surface 114b.
And penetrates into the hollow fiber membrane 114a from the lower surface 114c,
By passing through the side wall of the hollow fiber membrane 114a from the inside, impurities such as viruses adsorbed on the outer side wall of the hollow fiber membrane 114a are removed.

The cleaning liquid containing impurities such as viruses that has passed through the side wall of the hollow fiber membrane 114a flows into the eighth housing 108 through the inlet 119 and is discharged through a discharge path (not shown).

Although the pool water purifying apparatus according to the present invention has been described above in detail, the present invention is not limited to this, and various improvements and changes can be made without departing from the gist of the present invention. Of course, it is good.
