In the present invention, the pool includes not only a normal swimming pool but also a whirlpool arranged in a sports club, a Kurhaus, a health land, various types of recreational baths, hot springs and the like.

[0002]

2. Description of the Related Art With the recent boom in health, the number of health facilities such as sports clubs, multipurpose hot spring (bath) resorts, so-called Kurhaus, Kenko Land, etc. is increasing. These facilities are equipped with swimming pools, whirlpools such as jacuzzis and jet baths, various baths such as hitting hot water and fog baths, hot springs, etc. Is available.

Since such a health facility is absolutely safe and hygienic, it is necessary to strictly control the hygiene condition of the pool, especially the water quality. Therefore, the requirements for the purification device that determines the water quality of this pool are becoming more and more stringent, and the performance is being increased and the size is being increased accordingly.

The pool water purifying device is generally a filtering device for removing various impurities such as dust and hair contained in pool water, an adsorption purifying device for removing finer impurities such as oil, and sterilization of pool water. A sterilizing device for further performing, if necessary, a device for supplying a filter aid to the filtering device, heating of pool water in a warm water pool or bath, heating means, etc.
This is an expensive device that is composed of a large number of devices, pipes that connect these devices, and a control device that controls these devices. Particularly, a high-performance purification device is expensive, large-sized, and time-consuming to install.

However, in the conventional purifying device, the purifying material such as a filter is affected by temperature and the like, and the purifying ability of the purifying device fluctuates and deteriorates. Therefore, one unit can purify different types of pool water. Can not. Therefore, in facilities with a large number of pools such as Kurhaus, many expensive pool water purification devices are required, and in some cases, only the number of pools is required, so equipment and construction costs for the pool water purification system, and even running The cost will be extremely high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The pool water purification system of the present invention will be described below in detail with reference to the preferred embodiments shown in the accompanying drawings.

FIG. 1 conceptually shows a pool water purification system of the present invention (hereinafter referred to as a purification system). Although not described in the following description, valves, cocks, three-way cocks, check valves, solenoid valves, etc. are arranged at necessary locations in the piping and each device of the purification system in the illustrated example, and the pool water flow It is natural to control the road.

The purification system 10 shown in FIG. 1 is a system for purifying pool water (hereinafter referred to as water) of four pools 12A, 12B, 12C and 12D having different temperatures. It has a purification device 14 that is connected and purifies the water of all pools, and a filtration device 16A, 16B, 16C and 16D that is connected to the individual pools and filters the water of each pool.

In the purification system 10 of the illustrated example, the purification device 14 supplies the purified water to each pool from the supply line 18, and the water of each pool is supplied from the inflow line 20 through the filtration device connected to each pool. Inflow.

FIG. 2 shows a conceptual diagram of the purifying device 14.
The purification device 14 basically includes a pre-filter 22, a ceramic filter 24, sterilization tanks 26a and 26b,
It is composed of an adsorption purification tank 28 and a circulation pump 30.

In the illustrated example, the water in each pool flows into the purification device 14 through the inflow line 20 via the filtering device provided in each pool (see FIG. 1).

The inflowing water is sucked by the circulation pump 30 or is dropped with each pool so that the prefilter 2
2 is introduced to remove large impurities such as hair and dust.

Next, the water flows into the circulation pump 30,
It is discharged and flows into the ceramic filter 24.

The ceramic filter 24 has a large number of cylindrical ceramic filters inside, and water is filtered by passing through a wall from the outside of the ceramic filter to remove fine impurities such as oil discharged from the human body. Be done. Ceramic filters are extremely fine, eg 0.25 to 1 μ, which are preferred for filtering pools, especially hot water pools.
Ultrafine particles of about 0.25 to 1 μm, such as organic matter such as oil released from the human body, which has a three-dimensional filtration space of about m and cannot be filtered by a conventional filter, are also suitable. It is possible to filter.

Moreover, unlike the filters used conventionally, there is no difference in performance depending on the water temperature, so that water of any water temperature can be suitably filtered. In the purification system 10 of the present invention, by applying a ceramic filter to the purification device 14 and providing a filtration device in each pool,
This makes it possible to highly purify water from many types of pools with different water temperatures with a single purification device, and reduce the overall cost of the purification system and running costs.

The water discharged from the ceramic filter 24 flows into the sterilization tanks 26a and 26b for sterilization.
The sterilization tanks 26a and 26b are for sterilizing water by applying ozone and ultraviolet rays, an ultraviolet lamp and an ozone lamp are arranged inside, and water is sufficiently bubbled by introducing air from the outside. Stir and generate ozone, and sterilize water by this ozone and ultraviolet rays. In the purifying device 14, by using both of them together, an extremely high degree of sterilization becomes possible.

The water which has been sterilized is then adsorbed and purified by the adsorption tank 2.
Flow into 8. The adsorption purification tank 28 adsorbs bacteria and the like decomposed by the sterilization tanks 26a and 26b by activated carbon and zeolite and removes them contained in water.

The water discharged from the adsorption purification tank 28 is supplied to each pool from the supply line 18.

In the purifying apparatus 14 of the illustrated example, a filter aid tank 31 is connected to the ceramic filter 24. That is, in the illustrated example, the pool water filtering means is constituted by the filter aid supply means including the pre-filter 22, the ceramic filter 24, and the filter aid tank 31. The filter aid tank 31 is internally divided into two tanks, each of which is filled with a powdery filter aid such as diatomaceous earth and a mixture of fibrous filter aid such as pulp fiber and water as a filter aid. .

As mentioned above, the ceramic filter has 0.2
It has very fine pores of about 5 to 1 μm three-dimensionally, and if it is applied to purified water as it is, it will clog immediately, and in the worst case, an expensive ceramic filter cannot be used. Will be. Therefore, it is preferable that the filter aid layer is formed on the outer cylindrical portion of the cylindrical ceramic filter to prevent the ceramic filter from being clogged and facilitate the backwashing cleaning that is regularly performed.

Any known filter aid can be applied, and the method for forming the filter aid layer on the ceramic filter may be a known method.

Further, the purifying apparatus 14 of the illustrated example has a back washing / cleaning apparatus 32 for back washing the ceramic filter 24 as a preferable mode. The method of backwashing is not particularly limited, but preferably, the method of washing the ceramic filter disclosed in Japanese Patent Application No. 2-35029 by the present applicant is applied.

By applying the above-described purifying device 14 to the purifying system 10 of the present invention, it is possible to purify and sterilize water, which is not possible with the ordinary purifying device, and to keep each pool in a very hygienic state. Can be held at. In addition,
As a purifying device to which such a ceramic filter is applied, the one disclosed in Japanese Patent Application Laid-Open No. 2-137503 by the present applicant is preferably exemplified. Further, it goes without saying that an auxiliary tank, a heat exchanger, or the like may be provided if necessary.

In the purification system 10 of the present invention, the water in the pool is purified by the filtration device which is usually connected to each pool. In addition, in the purification system shown in FIG. 1, the basic configuration of each pool and the filtration device is the same, so the following description will be given to the pool 12.
A and the filtering device 16A are taken as an example.

In FIG. 3, the pool 12A and the filtering device 16 are shown.
A conceptual diagram of A is shown.

In the illustrated example, the pool 12A is basically a pool bath 34 and a heat exchanger 36 connected to a boiler or the like.
And, having a caustic soda and chlorine supply device not shown,
The water in the pool is kept at a predetermined water temperature by passing through the heat exchanger 36 as needed during circulation.

The filtering device 16A for purifying the water in the pool 12A is basically an overflow tank 37 for temporarily storing the water overflowed from the pool bath 34.
And a carbon filter tank 38 for filtering the water stored in the overflow tank 37, and a pump 40 which is a means for circulating water in the pool 12A.

The overflow tank 37 has a partition plate 42 which divides the tank into two tanks from above.
Water from the overflow line 44 flows into the a tank on the upstream side, while the water on the downstream side b flows into the carbon filter tank 38.
The tank is connected.

Impurities mixed in the water in the pool are not only those that can be removed by a filter such as dust and hair, but also many that are lightweight and float on the water, such as oil discharged from the human body. Therefore,
As described above, the impurities are captured above the tank a and the water below the overflow tank 37b is allowed to flow into the carbon filter tank 38, so that the water in the pool 12A is kept hygienic without applying the purification device 10 at all times. Things are possible. Moreover, by having the overflow tank 37, the water in the pool 12A can be adjusted by the water stored in the overflow tank 37. Therefore, the balance for adjusting the amount of water in the pool, which is always necessary in the conventional pool, is provided. The tank can be eliminated.

The impurities accumulated in the overflow tank 37 may be removed later when the purification device 14 purifies the water in the pool 12A.

The carbon filter tank 38 uses a carbon filter to remove impurities that do not float in the water, such as dust mixed in the pool water. The carbon filter is capable of filtering out normal fine particles and removes hair, dust, and other unnecessary impurities. It should be noted that what is applied to the filtering device of the present invention is not limited to the carbon filter,
Any of various filters applied to a normal pool cleaning device can be applied.

The water thus purified is supplied to the pump 4
0 to pool 12A.

In the purification system 10 of the present invention, the action of purifying the water in the pools 12A to 12D will be described below.

Normally, the sequence is automatically controlled according to the set program, and the water is purified (filtered) by the filtering devices 16A to 16D which are individually connected to each pool. Hereinafter, taking the pool 12A as an example,
The water overflowing from the pool bath 34 flows into the tank a of the overflow tank 37 via the overflow line 44.

As described above, since the overflow tank 37 is partitioned from above by the partition plate 42, light impurities such as oil coming out of the human body are accumulated above the tank a, and only clean water below is accumulated. Moves to tank b.

The water that has moved to the b tank flows into the carbon filter tank 38 from the line 45 by the head or by the suction force of the pump 40, hair and dust are removed by the carbon filter, and the pump 40 makes the line 4
Returned to pool 12A from 6 and 48. here,
When the water is below a predetermined temperature, it goes through the heat exchanger 36, and when it is above the predetermined temperature, it is returned directly to the pool bath 34 without passing through the heat exchanger 36.

In the purification system 10 of the illustrated example, normally, the pools 12A to 12D are purified by the filtration devices 16A to 16D individually arranged in this way.

Here, when the continuous purification by the filtering devices 16A to 16D exceeds a predetermined time, or when it is detected by a sensor or the like that the water stains exceed a predetermined value, water circulation is performed from the individual filtering devices. It is changed to the purifying device 14, and more sophisticated purification of water is performed.

Next, the pool 12A will be described as an example. When the continuous purification by the filtration device 16A exceeds the specified time,
Alternatively, when the sensor or the like detects that the contamination of the pool 12A has exceeded the specified value, first, the pump 4
0 stops, the lines 45 and 46 are closed, the line 50 connected to the inflow line 20 is opened, and the water in the overflow tank 36 flows into the purification device 14 through the line 50 and the inflow line 20. By the way, when the purifying device 14 has been circulating and purifying another pool, for example, pool water of the pool 12D, the line 50 is opened and the inflow line from the overflow tank of the filtering device 16D of the pool 12D to the purifying device 14 at the same time. Closed, pool 12D
The circulation inflow line from the filter to the filter device 16D is opened.
However, the supply line from the purification device 14 to the pool 12D is not closed until all the pool water of the purification device 14 and the pool 12D remaining in the line is returned to the pool 12D, and the circulation from the filtration device 16D to the pool 12D is not performed. The line is not opened either.

Here, the amount of water in the overflow tank 37 of the pool 12A is a predetermined amount, for example, the liquid level is the partition plate 42.
When the cleaning device 14 is located further downward and the cleaning device 14 is circulatingly cleaning another pool, for example, the pool 12D, the cleaning device 14
And when all the pool water of the pool 12D in the line is returned to the pool 12D, the line to the pool 12D connected to the supply line 18 is closed, and at the same time, the line 52 of the pool 12A connected to the supply line 18 is changed. The water that has been released and highly purified is pool 1 from the purification device 14.
2A is supplied.

If the water supplied from the purifier 14 passes through the heat exchanger 36 and is below the predetermined temperature, the water is circulated through the heat exchanger 36 and the water temperature is set to the predetermined temperature. It may be configured to supply the pool bath 34 later.

Further, it goes without saying that it is preferable that the above-mentioned line switching, opening and closing, and the like are gradually performed to prevent water knocking and the like.

The water that has flowed into the purifying device 14 is cleaned of dust and the like by the pre-filter 22, and then fine impurities such as oil discharged from the human body are further removed by the ceramic filter 24, and ultraviolet rays are supplied by the sterilization tanks 26a and 26b. , Ozone sterilized, bacteria and the like are removed in the adsorption septic tank 28, and the supply line 18, lines 52 and 48
Is supplied to the pool 12A.

When the purification device 14 completes the purification of the water of the pool 12A, the purification of the water of the pool 12A is switched to the filtration device 16A again, and then the filtration device (16B, 16C) of another pool to be subjected to the advanced purification. And 1
6D) and the purifying device 14 are switched.

Switching between the filtering devices 16A to 16D of each pool and the purifying device 14 may be automatically sequence-controlled according to a preset timing chart or program, and various sensors may be used. It may be carried out by detecting dirt of water. Also, both are used together and switching is usually performed according to sequence control.However, if a large number of people enter one pool at a time, the amount of water decreases drastically or the water suddenly becomes dirty. The pool may be preferentially purified, and the sequence control may be restored after the purification is completed.
The timing chart and program for sequence control may be optimally created by conducting experiments in advance. Also, it goes without saying that these may be changed according to the operating conditions.

The pool water purification system of the present invention as described above is not limited to the above-described embodiment, but a configuration in which another filtration tank or a sterilization tank is added, a configuration in which unnecessary components are deleted from the system, Further, the present invention can be applied to various configurations, such as a configuration in which a completely different purification device is added, depending on the use and scale of the pool to which it is applied. Further, the number of purification devices in the purification system is not limited to one, and a plurality of purification devices may be provided if necessary depending on the number of pools, the scale of the purification devices, and the like.

Although the pool water circulation 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 scope of the present invention. Of course you can go.
