Abstract

In order to be able to disinfect air and/or liquid in a simple and economical manner, this can be achieved according to the invention by means of a method and a generator with air inlet (9) to an ozone generator (1) with a source of UV light (5) for the development of ozone (10), which is thereafter fed to the place of use which, where conditioned air is concerned, can be a stable or stall, a ventilation plant or the like, while conditioned liquid can be fed to a fish tank, process water, drinking water and the like. The ozone, which is produced in a photochemical manner, corresponds to ozone generated by the rays of the sun and, unlike the ozone generated by high voltage, it is not dangerous for living organisms. On the contrary, it functions as a natural conditioning of air and liquid.

Description

A METHOD AND OZONE GENERATOR FOR THE CONDITIONING OF AIR AND/OR A LIQUID.
Background of the invention
The invention relates to a method for the conditioning of air and/or a liquid, a generator for the execution of the method and the use hereof.
Hitherto known methods for conditioning by means of ozone are based on the use of ozone produced in a high-voltage generator, the so-called corona ozone.
However, this high-voltage ozone is not pure, but comprises a mixture of 03, N02, N03, N205 and HN03, a mixture which is harmful and, in larger concentrations, even poisonous. Consequently, the use of ozone is therefore regulated by various directives for the protection of the environment and of those persons who come in contact with the ozone.
The ozone mixture is also very aggressive, i.e. it is strongly oxidizing and results in damage by corrosion of the surfaces which are exposed to it.
The result of the use of the mixture as a means of conditioning for air and liquid is therefore not satisfactory, partly because the ozone is not clean, as mentioned, and partly because the use of the gas is limited for reasons of protection.
Advantages of the invention
It is the object of the invention to improve the method for the conditioning of air and/or liquid, and this is achieved by producing the ozone which is introduced to the air and/or the liquid with an ozone generator which functions with UV light.
First and foremost, what is achieved hereby is that the ozone produced by means of UV light functions in a more expedient manner, in that it comes so close to the ozone generated by sunlight that it can be characterized as being a natural part of the atmosphere. Therefore, it will give rise to damage in the form of oxidation to only a slight degree, while on the other hand it will have an effective influence on particles in water and air without this giving rise to damage to animals or plants.
The difference is so convincing that the discovery must be considered as being substantial, in that the ozone produced by UV light opens possibilities for establishing a process which functions "naturally" under artificial conditions. In the following there will thus be provided examples of the use of this ozone for various purposes for which the ozone produced by high-voltage is unsuitable for reasons of the above-mentioned harmful effects caused by the gases mixed with the ozone.
As disclosed in claim 2, by conditioning with ozone and UV irradiation there is achieved a hitherto unknown good quality of air or water which can be used in the production or other places where there is need for disinfection. For example, there can hereby be established environments in stables and stalls with an air quality which corresponds to that which is most suitable for the animals, whereby there is achieved a considerable improvement in the conditions for the livestock and at the same time a safeguarding of the animals'- health conditions without the need for the supply of medicaments.
In the conditioning of liquid, for example for purposes of fish farming and aquacultures, growth rates and health con- ditions can be achieved which have not hitherto been possible, and this completely without the need for medica¬ ments or supplementary additives.
As disclosed in claim 3, alone the addition of ozone is sufficient to achieve an efficient disinfection and clean¬ ing.
As disclosed in claim 4, by using a generator provided with quartz lamps, around which the air or the liquid is con¬ ducted, the treatment becomes efficient and herewith economical.
As disclosed in claim 5, the mounting of guide-plates ensures a good mixing and irradiation.
As disclosed in claim 6, by using the method and the generator for the conditioning of air for animals, eggs during incubation and plants, an atmosphere is provided which enhances growth and health.
As disclosed in claim 7, by using the method and the gene¬ rator for the conditioning of water for marine animals and plants, a high yield and a high quality can be achieved even in closed systems.
As disclosed in claim 8, by using the method for the sterilization of water, an efficient and cheap cleaning is achieved without the use of chemical additives.
Finally, as disclosed in claim 9, it is expedient to supply ozone-enriched air to storage rooms for feedstuffs and other perishable products, in that the need for cooling the air can hereby be avoided.
The drawing In the following, example embodiments of the invention will be described in more detail with reference to the drawing,

fig. 2 shows a section through a UV-irradiator,
fig. 3 shows a section through a UV-ozone generator, and

Description of the example embodiment
In fig. 1 is shown an example of an ozone generator 1 with a tubular quartz lamp 5 which is connected to the mains electricity supply via an ignition device 7 and a coil 6. The lamp 5 radiates light at a wavelength of 185 nm. Around the lamp 5 there is mounted a spiral 8 for the generation of a helical movement of the air 9, which is supplied to the chamber 2 through the inlet pipe 3.
When the lamp 5 is lit, the air 9 will be pumped through the chamber and atmospheric air will be converted to ozone in an amount of 0.5-5.0 g 03/h, in that single oxygen atoms react with 02 during the formation of 03. There can hereby be achieved a gas mixture 10 with up to 15% 03, which is discharged from the chamber 2 through the outlet pipe 4. If pure 02 is introduced, the produced amount of 03 can be made 3.7 times greater.
In a corresponding manner, fig. 2 shows a UV irradiator 11 in which the lamp 12 radiates light at a wavelength of 754 nm, and is inserted in a quartz tube 13 in order to protect it against direct contact with the liquid. When the liquid 16 is fed through the inlet pipe 14, it is led around the lamp by means of the guide-plate 8 so that all of the liquid molecules are irradiated during their passage. The liquid is hereby effectively disinfected (sterilized). Out of regard for the loss of energy through the liquid, the distance from the lamp to the outer liquid layer must not exceed 1.5 Cm.
In the example shown in fig. 1 and 2, there is only one lamp in each chamber 2, but for greater requirements there is nothing to prevent several lamps being mounted in the same chamber. These lamps can be mounted mutually parallel and with the same mutual intervals.
In fig. 3 is shown a UV-ozone generator which comprises an ozone generator 1 and a UV generator 11 built together. The special featu"e of the generator is that the ozone- containing air 10 is led to the UV generator at the same level as the liquid 16 and is hereby mixed, after which this mixture is irradiated with UV in the chamber, and is led out as a conditioned liquid/ozone mixture 18 which can be supplied to the desired place.
Where only the supply of ozone is required, ozone 10 from the ozone generator 1 can be fed directly to the liquid.
In fig. 4 is shown an example of the use of conditioned water in a fish tank 21. In the bottom of the tank there is mounted a discharge pipe 22 through which water and the solid precipitating particles can be led to a sludge trap 23, where the solid particles are precipitated, while the water is fed via a pump 24 to the UV generator 11. This UV generator 11 is also supplied with ozone from the ozone generator 1, after which the mixture 18 is led through the UV generator and conducted through an inlet pipe 20 to the tank 21. The water is herewith disinfected in a simple and inexpensive manner, whereby the cleanliness of the water is ensured. Many advantages are achieved, in that the fish are not exposed to attack by disease and their gills are kept healthy, which means that the need for the addition of medicaments is eliminated. This results in optimum metabolism and herewith growth. Moreover, the feedstuff will not have any influence on the quality of the water, in that the dissolved flavour molecules will disappear in the conditioning process. Therefore, since the water is held free of these inconvenient flavour molecules, the fish will not assume the taste of these molecules. Consequently, since it is the water and not the feed which gives the fish its taste, use will be able to be made of fishfeed which is otherwise unusable. All in all, an improved water environ- ment is achieved for the fish, which are held at high growth rates and hereby quickly reach sexual maturity in comparison with what can normally be achieved in such systems.
By cleaning the water by keeping it free of bacteria, virus and fungus, an extremely rational fish and marine-plant cultivation can be achieved. Furthermore, surprisingly it has proved that the light-generated ozone can be led directly into the fish water without any harm to the fish.
It will also prove advantageous to use the conditioned water 18 as irrigation water in cultivation systems with programmed watering, e.g. ebb-and-flow systems, in that the water will not need to be discharged as waste water but be able to be recirculated after conditioning. This results in considerable savings of water, and herewith an improved economy- without any risk of plant diseases hereby being spread.
In a corresponding manner, waste water can be sterilized by means of light-generated ozone, whereby the bacteria content can be limited without the use of chemical additives, which is very beneficial to the environment.
Noteworthy results have also been achieved in the conditioning of air. In stables and stalls with a high humidity, a conditioning will be able to be achieved by leading the air to the generator through the inlet pipe 14. By leading the disinfected air with high ozone content to a stable or the like, the animals will achieve a hitherto- unknown good growth and general condition. By striving to provide an ozone content in the air of between 0.05 and 0.1 ppm, the animals will thrive to an optimum degree without the need of medicaments for combating diseases arising from air-borne infections etc.
Where pigsties are concerned, the ozone content will not only provide the same good growth conditions but also re¬ duce the amount of ammonia in the air, hereby improving the animals' conditions of development in a decisive manner. Consequently, they do not suffer any stress symptoms and their mutual unruliness ceases completely.
Finally, with regard to chicken runs and similar poultry and brooding-houses, it should be mentioned that surprising results have been achieved by leading conditioned air to the eggs during incubation, in that it would appear that the spreading of salmonella bacteria in the eggs can hereby be avoided.
Airborne disease-promoting bacteria and other micro¬ organisms can give rise to sickness among people as well as animals. By leading light-generated ozone to the air in suitable concentrations, such bacteria and the like can be killed, thus ensuring better growth and well-being. More- over, this pure ozone has surprisingly proved to be non- toxic when inhaled by people in its presence. To sum up, it can be said that the light-generated ozone generated by the invention enhances the balance produced by nature, and in such a manner that the conditions of life created are as natural as possible, even under conditions which would otherwise result in poor development and growth.
