Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating filtration pool and a pool water circulation filtration method, in which water in a pool is filtered to perform proper purification and to be recycled.

[0002]

It is known that the quality of pool water can be improved by limiting the number of swimmers so that the inflow of pollutants can be reduced to maintain good quality pool water. Moreover, if fresh water is constantly supplied to the pool, the water quality will not deteriorate. However, this is an ideal, and in reality, the limitation of the number of swimmers will keep out those who wish to swim, and there is a problem that it is not possible to meet the wishes of swimmers, and there is also a problem in management. Cause Supplying a large amount of fresh water is difficult to replenish with fresh water, and even if it can be supplied, the cost of water and sewer increases, and the loss of thermal energy due to the discharge of hot water in the hot water pool. Occurs.

Therefore, the circulating use of pool water is widely practiced. In the conventional pool, pool water is collected from the bottom collection port provided at the bottom of the pool.
The pool recovered water was supplied from the side of the pool. In this method, dirty pool water is collected only from a part around the bottom recovery port, and it is long to recover dirty water from a part away from the bottom recovery port, for example, the upper layer or the corner. It was time consuming and difficult. Also, ▲
When the sterilant is injected into the pool water that has been filtered by an excess device and sent to the pool, the specific gravity of the sterilant is heavier than that of water and it accumulates at the bottom of the pool, making it impossible to sterilize the entire pool water efficiently. There was a defect that the water quality of the entire pool could not be made uniform.

According to the "hygienic standards for swimming pools" presented by the Ministry of Health and Welfare, in principle the filter device is to be operated all day, but when a person is swimming,
The pool water is agitated by people, and the dirt components in the pool water are in a uniform state, so the pool water is circulated.
The dirt component can be removed by filtering. However, when people are not swimming, such as at night, the agitation will be weak, so heavy dirt components will settle, light dirt components will float, and the drawback that efficient circulation can not be done is remarkable. Met. By the way, in the swimming pool, the Ministry of Health,
The water quality of the pool is determined by the Ministry of Education and the Japanese Society of Pharmacists, and when circulating the pool water, a circulation filtration device or the like is required, and the introduction method is stipulated.

As the filtration device, diatomaceous earth type, sand layer type and cartridge type are mainly used, and in addition, ceramic filtration material filtration device, hollow fiber membrane filtration device, etc. are used. Has been done. In addition, it is stipulated that a sterilizing agent such as a chlorine agent is injected so that the residual chlorine concentration is 0.4 mg / l to 1.0 mg / l. Recently, chlorine dioxide, ozone,
Pools that use UV light have also been proposed. Hollow fiber membrane ▲
Although the equipment is expensive, it has the best performance.
Even the finest particles can be removed, and the use of ozone and ultraviolet rays has the effect of eliminating the irritating odor caused by the generation of chloramine as in the case of using a chlorine agent because organic substances are decomposed. However, this effect also cannot circulate the original effect if some pool water is processed without efficiently circulating the whole pool water, and problems remain in hygienic safety and comfort. . In other words, unless efficient circulation is performed, it is impossible to improve the water quality of the pool as a whole, no matter how well the filtration device and sterilization device are installed. In addition, in the conventional pool, overflow water that overflows from the pool due to the rise in water level due to people entering the pool was discarded in most cases. However, recently, due to problems such as drought in summer, there is a strong demand for reuse of pool water as much as possible, and recovery of overflow water is being attempted.

However, in the conventional overflow water recovery method, due to the structural problem of the recovery part, the recovered water is contaminated with filth such as saliva and sputum exhaled by the swimmer. According to the above-mentioned “hygienic standards for swimming pools” of the Ministry of Health and Welfare, in such cases, it is instructed to install a filter device exclusively for overflow water in order to sufficiently remove such dirt, but However, it is difficult to remove organic substances such as saliva and sputum, and there is a problem that the excessive load increases.

[0007] Further, if the pool side where a swimmer walks and stands to enter the pool is simplified to improve the appearance and ease of use, a drain pipe from the overflow water recovery port is opened to the pool side. Since the structure is connected to the drainage groove around the pool, the cleaning water on the poolside is also drained at the same time, so this water is also filtered.

Further, since there is a vertical pipe in the pipe from the overflow water recovery port to the storage pit and the filtration device, there is a drawback that annoying noise is generated when the water flows down. This noise is generated by the pool water circulation at night ▲
I am causing noise problems in the past.

Further, in ordinary pool water quality control, the manager controls the injection of the chlorine agent by measuring the residual chlorine concentration of the pool water without using an automatic control device, so that the residual chlorine concentration can be precisely controlled. There was also a problem that the residual chlorine concentration in the pool water became higher than the specified range, the residual chlorine concentration became too high, and the hair was hurt, the swimsuit hurt, and the eyes were irritated. . If it is lower than the specified range, the sterilization effect becomes small. Moreover, although it is similar to the above-mentioned problem, there is also a problem that it is impossible to make a large amount of pool water into a uniform water quality and concentration unless the water circulation is performed properly.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention provides circulation of pool water.
Excessively, dirty pool water can be efficiently collected regardless of fluctuations in circulation efficiency due to different stirring conditions in pool water when people are swimming and when they are not swimming at night. , By injecting purified water evenly into the pool, efficient circulation is performed, the water quality of the entire pool is made uniform, and the sterilant injection amount is automatically controlled to be within the water quality standard as little as possible. However, human sputum, saliva, etc., pool side washing water and drainage will not enter the overflow recovery port.
Moreover, the present invention provides a circulation method that allows good circulation even when there are no swimmers at night, etc., and that has a high over-efficiency circulation type and a pool water circulation method.

[0012]

In the present invention, the pool water recovery path is divided into two systems, an overflow water recovery path and a path for recovering water from the bottom of the pool, and the side of the supply path of the filtered pool recovery water to the pool main body It is composed of two systems, one is a supply port and the other is a bottom supply port, and the bottom supply port injects upwards from the bottom as a whole, so the specific gravity contains the sterilizing agent filtered by a filtration device. The heavy pool water does not stay at the bottom of the pool and spreads throughout the pool, and heavy turbid components do not stay, so efficient circulation is possible and the water quality of the entire pool is always uniform. Is played. Especially in the conventional pool, the pool water is not stirred at all, and even when people are not swimming at night, when circulation efficiency is poor, efficient circulation is achieved by stirring with air and circulation pump The effect of being able to pass is achieved. Therefore, there is an advantage that the filtration device can be downsized.

Further, when air is injected from the bottom supply port, fine particles or the like swimming in the pool water adhere to the bubbles and float on the pool water surface and can be collected from the overflow water recovery port. In addition, by injecting air into the pool water, the components such as chloramine dissolved in the water diffuse into the atmosphere, the effect of eliminating the odor caused by chloramine, and the pool water is oxidized and the amount of oxygen is increased, resulting in activity. It also has the effect of being converted. In this case, the indoor pool needs ventilation. Also, although the water flow at the corners is poor, if the corners of the pool are provided with rounded corners, the pool water will flow smoothly, stagnation will be less likely to occur, and circulation efficiency will be further improved.

Further, according to the present invention, the sputum for discharging sputum and saliva without draining the sputum and saliva, and the saliva waste discharge port are separately formed above the overflow water recovery port, so that sputum is discharged to the overflow water. , Saliva, etc. are not mixed in, so
Overload is reduced. Unlike ordinary waste in the pool, such waste is not only difficult to pass through but also has a problem that the life expectancy of the filter material is reduced and the number of backwashing is increased. Therefore, if such dirt is not taken into the filter device, not only the load of organic substances such as saliva and sputum on the filter device is reduced, but also a filter device dedicated to overflow water is installed. Without one, ▲ ro ▼ Circulate with excess machine ▲ ro ▼
It is also possible to pass. Further, by forming the pool-around discharge port around the pool body, there is no fear that cleaning water around the pool will be mixed with overflow water. Further, by making the pipe from the overflow water recovery port an inclined pipe, it is possible to eliminate the noise that feels when the water flows down as described above.

Further, the pool recovered water is sampled before being filtered, pH, residual chlorine and redox potential are measured, and the supply amounts of the pH adjusting agent supply device and the sterilizing agent supply device are automatically controlled according to the measurement results. Then, the sterilant supply amount can be kept within the water quality standard with a minimum amount. This is because the sterilizing effect of a sterilizing agent such as a chlorine agent greatly depends on the pH, so that the sterilizing effect becomes high. This is because the residual chlorine concentration of 0.4 mg / l to 1.0 mg / l, which is the water quality standard, can be achieved. In the present invention, as described above, since the pool water is efficiently circulated, it is needless to say that the entire pool water can be efficiently sterilized and a uniform concentration can be obtained. There is also the effect that only one sampling place is required. Measuring the redox potential is also useful because the sterilization state of pool water can be ascertained. By measuring the electrical conductivity and detecting the accumulated amount of soluble substances such as chlorine ions, urea, sodium ions, etc., when the accumulated amount becomes large, make-up water is supplied or it is quickly attached through the ion exchange tower. By removing it, it is possible to prevent galvanic corrosion of metal pipes and boilers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a configuration explanatory view showing an embodiment of the present invention. Reference numeral 1 denotes a groove-shaped intake port for collecting overflow water formed on the upper side surface of the pool body, from which overflow water flows. Reference numeral 2 is a sputum and saliva discharge port arranged with an intake gap provided above the overflow water recovery port, and has a gutter-shaped structure in this example. Such a gutter may have a semicircular cross section or a polygonal shape. In this embodiment, as can be seen from the drawing, the overflow water recovery port, the sputum, and the saliva discharge port have a two-story structure. Reference numeral 6 is a pool-side drainage groove provided on the poolside, and the recovered water collected from this is discharged together with the recovered material collected from the sputum and saliva outlet.

In the embodiment, the sputum and saliva discharge port 2 is slightly projected into the pool, and is covered with an elastic material such as rubber or neoprene. The overflow water intake 1 is arranged below the sputum and saliva outlet. This structure has the advantage that the overflow water recovery port 1 is not visible and the pool looks neat, and because it is covered with the elastic material that forms the saliva and sputum discharge ports, it can be used when a person hits it. It is a protection and there is no danger. The overflow water recovery port 1 is formed of a rubber U-shaped groove. Of course, it is not limited to this, but a pipe cut in half may be used, but a smooth surface is preferable and a somewhat elastic one has a better water flow and This is preferable because no sound is generated.

From the sputum and saliva outlet 2 to the poolside drain 6 and poolside 7, there is a slight inclination toward the pool so that the drainage around the pool naturally becomes poolside drain 6 and sputum and saliva. Although it is formed so as to be collected at the outlet 2, the present invention is not limited to this, and it may be horizontal from the sputum or saliva outlet to the poolside or may be raised. The sputum and saliva outlets may be provided around the entire circumference of the pool or may be provided at part of the poolside. Further, since a person who has spit out to a sputum or saliva outlet usually sprays water with his / her hands, it is not necessary to constantly flush water, but it is preferable to always flush water from a sanitary point of view and a clean appearance. 3 is a bottom water intake. In this embodiment, as shown in the drawing, the groove is formed in an elongated shape, but the shape, place, number, etc. are not particularly limited, and a circular shape may be formed in two places.

Reference numeral 4 denotes a side surface supply port, and in this example, three side surface supply ports are formed uniformly on one side surface. Although only one side surface is shown in the drawing for the sake of convenience, it is preferable to form a large number on all side surfaces in terms of circulation efficiency. Reference numeral 5 denotes a bottom supply port, and in this example, it is formed uniformly in three rows in the width direction of the pool bottom. Water and air can be blown upward at certain intervals into the row of bottom supply ports, as indicated by arrows in the drawing. Of course, the water and air supply ports may be formed separately for exclusive use. Further, from the viewpoint of circulation efficiency, it is preferable to form many supply ports evenly over the entire bottom surface.

Reference numeral 8 denotes an overflow water storage pit for temporarily storing overflow water, which is stored through an overflow water delivery pipe 9. The overflow water delivery pipe 9 is formed by an inclined pipe in order to prevent the generation of a sound of water flowing down. Although not shown in the drawings, if a simple prefilter such as a bag filter is installed in the middle of the overflow water delivery pipe 9, the first first filter will be described later.
This is effective in reducing the load on the excess device.

Reference numeral 10 denotes a sensor for measuring pH, residual chlorine and redox potential, which is measured by sampling overflow water. Reference numeral 11 denotes a control device for monitoring the measurement result and controlling the supply amount of the pH adjusting agent and the sterilizing agent based on the measurement result. Known devices can be used for 10 and 11. Reference numeral 12 is a pH adjusting agent feeder, which supplies sodium hydroxide, calcium hydroxide or the like to the overflow water recovery pit 8 if it is acidified or hydrochloric acid or sulfuric acid if it is alkaline according to a control signal from the controller 11. . In the example, overflow water was measured, and the pH adjusting agent was supplied to the overflow water storage pit 8. However, the measuring place and the supplying place are not limited to this, and the collected water collected from the bottom intake port is measured, It may be supplied to this. Reference numeral 14 is a first filtration device provided exclusively for filtering the overflow recovered water, which is a sand layer type filtration device.
A transponder is used. Of course, other types of filtration devices can be used. A circulation pump 21 and a chemical dosing device 19 are installed between the overflow water storage pit 8 and the first filtration device. The chemical dosing device 19 supplies a coagulant for aggregating fine particles in water. Good over-effect.

As the coagulant, for example, 1 ppm of polyaluminum chloride is supplied with respect to the excess flow rate. If the capacity of the overflow water recovery pit 8 is small, the first ▲
Filter ▼ Bottom intake 3 to secure backwash water for filtration device 14.
Therefore, the first filtration device 14 is also provided with piping. That is, when the first filtration device 14 is backwashed, the pool recovered water from the bottom recovery port 3 is used. If the capacity of the overflow stored water pit 8 is sufficiently large without any problem, it is not necessary to configure in this way.

The pool recovered water filtered by the first filtering device 14 is divided into two systems, and is supplied to the pool main body from the side surface supply port 4 and the bottom supply port 5. A sterilizer 13 is installed in front of the pool body, and a sterilizing agent is supplied by a control signal from the controller 11. For example, in the examples, a 12% solution of sodium hypochlorite is supplied. The pool recovered water recovered from the bottom water intake port 3 is divided into two systems, that is, the system for backwashing the first filtration device 14 and the system for the second filtration device 15 described above. The bottom recovered water is the second filtration water except when the first filtration device 14 is backwashed.
▼ Go to the transit device 15.

In the embodiment, a sand layer type filtering device is also used as the second filtering device 15. 1st filter device 1
Other types of filtration devices can be used as in the case of 4. A circulation pump 21, a chemical injector 19, and an ozone generator 16 are installed between the bottom water intake 3 and the second filtration device 15. The ozone generator 16 supplies ozone to the pool recovered water. Since ozone has a strong oxidizing power, it has an effect of decomposing organic substances. Also, in combination with an ultraviolet irradiation device,
Irradiating the pool water with ultraviolet rays is also effective for enhancing the effect of ozone and increasing the transparency of the water.

The pool-recovered water that has been subjected to ozone treatment and filtered by the second filtration device 15 is subsequently subjected to waste ozone treatment through the waste ozone treatment device 17 so that ozone gas does not come out to the pool. In the example, an activated carbon adsorption tower was used as the waste ozone treatment device 17. The pool recovery water that has been subjected to the exhaust ozone treatment is filtered by the first filtration device, and then the side supply port 4 is filtered.
After being heated by the heat exchanger 18, it is supplied to the pool body from the bottom supply port 5 together with the pool recovered water other than that supplied to the pool from the pool. As described above, before being supplied to the pool body, the sterilizer 13 supplies the sterilizing agent by the control signal from the control device 11. Reference numeral 20 denotes a compressor, which is used to supply air from the bottom supply port 5. A blower or the like may be used as long as it can supply air.

Although the present embodiment has such a structure, the pool recovered water filtered by the second filtering device may be supplied from the side surface supply port 4, or it may be exclusively used for overflow water.
It is also possible to filter all pool collected water with one filtering device without providing a filtering device. Since spit and sputum do not mix, one machine is enough. Further, the installation location of the chemical injector, the ozone generator, the heat exchanger, etc. is not limited to this, and may be omitted if not particularly required. Although it is a ratio of the supply amount from the side surface supply port 4 and the bottom supply port 5, it is preferable to increase the supply amount from the bottom supply port 5 in terms of circulation efficiency.

[0027]

According to the invention, the water circulation effect is improved, and the water quality of the entire pool can be made uniform. In addition, sputum, saliva, and wastewater around the pool do not mix into the overflow water, so there is no need to filter it. Therefore, the filtration device is not wasted, the filtration device can be made compact, the water reuse efficiency is improved, and the heat energy cost is reduced in the case of a hot water pool. In addition, only one sampling location for water quality measurement is required, the sterilant is supplied uniformly, control is easy, and the amount of sterilant used is efficient. Further, the water is activated by the air supply at night and the transparency of the water is improved, and the comfort of the swimmer is increased.
