Description

[Detailed description of the invention] [Industrial application field] This invention is a swimming pool that always reliably provides the most effective ozone to the water in the pool and seeks a sanitary and healthy environment. This invention relates to a pool purification device.

[Conventional technology]

In recent years, with the rapid use of swimming pools, the number of swimmers has increased and various facility improvements have been made.
At the same time, the degree of water contamination has become a problem, and the introduction of medicinal materials has been cited as a means of managing it.

Incidentally, in the case of a heated pool, it is difficult to expect much from the oxidizing power because the concentration of dissolved oxygen in the water is low, and the oxidizable substances in the water are mainly oxidized by residual chlorine. Therefore, as the number of swimmers increased, the amount of chlorine injected had to be increased, but this increase not only caused eye irritation but also caused irritation.

Recently, as a means to eliminate such drawbacks, since carcinogenicity due to the formation of trihalomethanes due to hypochlorite in water is a problem, sterilization and purification using the strong oxidizing power of ozone injection instead of chlorine injection has been proposed. The deodorizing power has attracted attention, and various methods have been developed in the industry for injecting ozone into the pool water by installing an ozone generator in the pool water overcirculation system.

That is, as an example of this, as shown in FIG.
This water is temporarily stored in the return water tank 2, and then passes through the circuit of return water pipe B, air catcher 4, circulation pump 3, filter 8, and heat exchanger 9, and then enters the pool 5 from the return water port C. It will be refluxed again.
Further, the water (contaminated water) from the bottom suction port A flows to the connection part B of the pipe B, joins with the water from the water return tank 2, and is returned through the same route as above.

During such water return, the ozone generator 1, sterilization device 10, flocculation device 11, and neutralization device 12 were operated according to the water quality of the pool to purify and maintain the water in the tank.

[The problem that the idea attempts to solve]

However, in the above-mentioned conventional method, unreacted surplus ozone is normally sent from the top 8' of the filter 8 or the reaction device to the treatment device 13 for activated carbon, etc., through the surplus ozone supply pipe 1a, where it is absorbed and decomposed, deodorized, and then exhausted. Although it is discharged outdoors from the port 14, it is of course very uneconomical to dispose of a part of the ozone created at the cost of electricity to the outside in an unreacted state. There were drawbacks such as the need for various troubles to use and replace activated carbon for deodorization.

In view of the uneconomical problem of the conventional method, the purpose of the present invention is to send surplus ozone that would normally be exhausted to a water return tank without the need for the above-mentioned exhaust ozone treatment equipment. It is an object of the present invention to provide a purifying device for a swimming pool that not only improves the sterilizing and purifying function but also reliably expects economical effects.

[Means to solve the problem]

In order to achieve the above object, the purification device of the present invention connects the overblown water return tank 2, circulation pump 3, filter 8, heat exchanger 9, etc. via piping B, and overcirculates the water. In a swimming pool purification device which forms a circuit and incorporates an ozone generator 1 into the circulation circuit, unreacted surplus ozone discharged from the filter 8 is sent to a return water tank 2 via a surplus ozone supply pipe A. Its feature is that it is also equipped with a recirculation circuit for injecting excess ozone.

[Effect]

The present invention has the above-mentioned configuration, and as explained in detail in the section of the prior art, during pool overcirculation operation, surplus ozone discharged from the top discharge port 8' of the filter 8 is removed from the surplus ozone supply pipe. Through A, the water is ejected into the return tank 2 to perform primary sterilization of the water in the tank, which has a relatively high concentration of contaminants.

[Examples and their effects]

Hereinafter, a hot water pool will be described in detail with reference to FIG. 2 as an embodiment of the present invention. Reference numeral 2 denotes a return tank for overblown water flowing from an overblown gutter 6 provided around the pool 5 to an overblown pipe 6a; numeral 8 is a circulation pump having the function of returning the water from the water return tank 2 back into the pool 5; numeral 8 is a filter; and numeral 9 is a heat exchanger, which are connected to each other by piping B.

The other reference numerals 4 are a hair catcher, 10 is a sterilization device, 11 is a flocculation device, 12 is a neutralization device, and 7 is a replenishment water tank. .

The present invention has an ozone generator 1 in the above configuration.
is connected to the front of the filter device 8 in the pipe B, and the ozone discharge port 8' at the top of the filter device 8 is connected to the above-mentioned return water tank 2 by the surplus ozone air supply pipe A, and the exhausted surplus ozone is spouted into the return water tank 2. It is configured as follows.

The volume of the return water tank 2 is sufficient to accommodate the increased amount of water used by a large number of people in the pool or when people jump into the pool, so that the reaction of unreacted excess ozone can take place sufficiently. Since back pressure from the circulation pump exists in the surplus ozone air supply pipe A, the surplus ozone injected into the water return tank 2 is naturally agitated by the ejection and more effective oxidation is carried out, increasing the absorption effect. Needless to say, it has improved.

Therefore, the primary sterilization and purification of the wastewater, which is caused by the discharged surplus ozone and flows into the return water tank 2, is carried out reliably and satisfactorily.
In combination with the purifying action of the ozone injection, sterilization device 10, neutralization device, etc., it is possible to reliably and easily provide effective pool water that meets legal standards.

[Effect of idea]

As described above, the swimming pool purification device according to the present invention utilizes ozone by injecting the unreacted surplus ozone, which was conventionally exhausted outside, into the highly contaminated return water tank 2 without disposing of it at all. Not only can the total amount be greatly suppressed, but there is no need for exhaust ozone treatment equipment using activated carbon or the like, exhaust equipment, etc., and the labor and economic effects associated with these are enormous.

It goes without saying that the present invention is not limited to only swimming pools, but can be widely used for other bath equipment such as bathtubs and aquariums.
