Description

Technical field

The present invention relates to an apparatus for the production and application of ozone for the treatment of water, in particular for the treatment of water in swimming pools, in particular in domestic swimming pools and in spa-type therapeutic and rehabilitation pools.

BACKGROUND OF THE INVENTION

Concerning the problems of production and application of ozone for water treatment, it can be said that at present only devices of specific design, narrowly specialized in one, quite specific application area, are known. For example, devices for the treatment of drinking water with ozone have been known for some time - the so-called chamber mixing of ozone with water. This drinking water treatment is applicable instead of the more common, but more problematic chlorination in terms of drinking water quality. Another type of known apparatus, in turn, is intended for the preparation of so-called ozone water (ie water and a higher concentration of dispersed ozone) by bubbling ozone through water. The treated water is then used primarily for therapeutic drinking cures.

A disadvantage of the above-described devices is the fact that the problem of production and application of ozone for water treatment is always solved only from a narrowly specialized point of view, or they are also very complicated in terms of arrangement. This inevitably implies their limited applicability for water treatment, for example in domestic pools and pools of therapeutic and rehabilitation facilities of the spa type, mainly due to high acquisition or operating costs.

SUMMARY OF THE INVENTION

The ozone treatment and production plant according to the invention contributes to overcoming the above-mentioned drawbacks. The device consists of an inlet module (with an oxygen pressure vessel with a pressure reducing valve or an air pump) and an ozone generator connected thereto on the principle of a high-voltage coroner discharge. A water treatment module is then connected to the ozone generator, which comprises an injector, a check relief valve and a quartz mixer, possibly a residual ozone destroyer.

The air pump of the inlet module is preferably supplemented with an air dryer and has adjustable output. The inlet module, including the air dryer, can also advantageously be integrated into the water treatment module.

The quartz mixer of the water treatment module consists of a hermetically sealed tubular body filled with silica quartz and / or quartz crystals having a particle size of 5 to 15 mm, which body is equipped with an ozone water supply and removal. Another variant is a quartz mixer whose hermetically sealed tubular body is partially filled with quartz pulp and / or quartz crystals having a particle size of 5 to 15 mm and partly with activated carbon.

The residual ozone destructor may be formed, for example, by an activated carbon tube filter.

Polytetrafluoroethylene tubing is preferably used to connect the individual elements of the universal ozone production and application device.

The main advantage of the ozone treatment and production plant according to the present invention is, compared to existing ozone treatment plants, to achieve a more efficient dispersion (distribution) of very fine ozone bubbles in the water due to the inclusion of the newly solved component

A quartz mixer. This, for example, has a very positive effect on the long-term quality of treated water in swimming pools.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic diagram of an exemplary arrangement for producing and applying ozone for the treatment of water in swimming pools.

DETAILED DESCRIPTION OF THE INVENTION

An apparatus for producing and applying ozone for the treatment of pool water in an exemplary embodiment (see FIG. 1) is incorporated into a water circulation system comprising a circulating pump 14 with a sand filter 15.

The actual plant for the production and application of ozone consists of an ozone generator 3 to which a water treatment module 2 is connected. This module comprises an injector 4, a check relief valve 6 and a quartz mixer 5. The inlet module of the device, including the air dryer 7, is in this case integrated into the water treatment module 2 - the ozone production air is entrained into the ozone generator 3 by water flowing through the injector 4 in the direction of arrow 16.

By way of illustration, the oxygen and ozone dose setting required for full ozone so that water is replaced and properly disinfected at least once every 24 hours without the use of chemical products is shown in the following table:

Pool water volume [m ³ ] Ozone required [g / h] Pump output [kW] Circulation time at 22 ° C [h / day] 10 0.90 0.35 2x2 15 Dec 1,25 0.35 2x3 20 May 1.80 0.45 2x3 25 2.25 0.45 2 x 3.5 30 2.80 0.55 2x3,5 35 3.15 0.65 2x4,1 40 3.60 0.80 2x3,3 45 4.00 1.20 2x3,2

The ozone generator 3 operates on the principle of high voltage corona discharge. The function of the injector 4 is to mix the ozone with the water it treats.

The injector 4 is followed by a quartz mixer 5. This qualitatively newly designed part of the water treatment module 2 consists of a tubular body of 110 mm diameter polypropylene with the necessary sieves and lids for closing. The tubular body is filled with fine and completely pure mineral quartz with a size of 5 to 15 mm, it is equipped with an inlet and outlet of ozonated water and hermetically closed with lids. Another variant is a quartz mixer whose hermetically sealed tubular body is partially filled with activated carbon. The function of the quartz mixer 5 is that the water already passing through it as a mixture with ozone is cleaned very well here by contact with the quartz, and the very fine ozone bubbles are effectively dispersed therein. So much more ozone remains dispersed in the water, the water is very well disinfected and only a slight amount of ozone leaves the water. The water is beautifully clear, clean, shiny and very pleasant to use in the pool.

-2GB 295267 B6

Another variant of the quartz mixer 5 can be used to remove even slight odors.

In this case, only the tubular body is partially filled with quartz pulp, with the remaining parts being filled with activated carbon.

Check valve 6 prevents accidental ingress of water into the ozone generator 3.

The device can also be supplemented with ozone concentration meters, both with an ozone concentration meter above the water level in the pool (measures the residual ozone concentration) and a flow meter for the ozone flow entering the injector 4 (measures the ozone flow rate into the water).

Interconnection of individual elements of the device is realized by polytetrafluoroethylene tubing.

The device according to the embodiment according to Fig. 1 keeps the water in the pool clean, without the limescale build-up, dust, dirt, insect residues, etc., on the walls and the bottom of the pool, even at temperature, water to 36 ° C, only by maintaining the pH of the water in the range of 7.2 to 7.6. Organic impurities will burn ozone, mineral impurities (such as sand) will suffice once in a while - depending on the pool attendance. This technology not only saves time for water maintenance, but also provides treated water that has positive health effects. The skin after bathing is very smooth, itchy - it is embalmed, it eliminates inflammation, joint pain, rheumatism, acne; water smells like a thunderstorm. In addition to pH adjusters, no other chemical products are required. With this in mind, the return on investment in ozone pool water treatment equipment is no more than 2.5 years.
