Definitions
- DE 100 13 841 specifies a method for keeping the ozone and ion production constant with the aid of an electrical control circuit. Because ozone and ion production is subject to a wide variety of influences and also because during long-term operation the electrical and mechanical values of the ozone and ion Change production used assemblies. This has an advantageous effect on ozone and ion production, so that no constant conditions can be achieved without the use of this invention, which is of concern with the known toxicity of ozone.
- DE 196 51 403.7 proposes an ozone and ion generator in the flow direction upstream of the evaporator in air conditioning systems, e.g. Motor vehicles, buildings or compact air conditioning systems to arrange an ozone and ion source and to flow around the humid evaporator with ozone and air ions.
- air conditioning systems e.g. Motor vehicles, buildings or compact air conditioning systems to arrange an ozone and ion source and to flow around the humid evaporator with ozone and air ions.
- ozone dissolves in the water on the surface of the evaporator and forms hydro radicals, which have an extremely bactericidal and fungicidal effect and have been tested and reliably prevent any biological activity on the surface of the evaporator.
- a catalyst is proposed which breaks down excess ozone into normal diatomic oxygen. This invention is advantageous for the safe, sterile operation of air conditioning systems of all kinds, in particular those in motor vehicles.
- DE 199 33 180.4 it was proposed in DE 199 33 180.4 to arrange the ozone and ion source in front of the air inlet and in front of the air filter.
- This air filter is equipped in such a way that excess ozone is catalytically broken down.
- DE 101 03 905.0 proposes to enrich the air with ozone and oxygen ions in a tumble dryer, with the result that germs and odor-carrying substances in the (moist) laundry are killed.
- the complex mechanism of action and in particular the action of ozone dissolved in water (hydroradicals are formed) has been described in more detail.
- the effect is primarily based on the oxidative chemical effect of the three-atom and one-atom ozone.
- the proposed solutions to problems make the handling of ozonization devices safer and more predictable. Due to the need to adjust the ozone concentration in the blown air to one of the American Environmental Protection Agency (US-EPA / Environment Protection Agency) and the DIN / EN standard EN 60335-2-65; (1995) to limit the mandatory value so that an ozone level of more than 50ppb can never arise in the rooms thus ventilated, the patent application presented here deals with the beneficial effects of ionized air ions and the technical and safe use of active oxygen ions Compliance with the required limit values.
- both ions and ozone are formed.
- the chemical reactivity of ozone is higher than the chemical reactivity of oxygen ions.
- the usefulness of airborne oxygen ions has been described in numerous works and is a principle of nature for cleaning the air from particles as well as for sterilizing air and surfaces.
- the ozone added to the air flow to be treated must be destroyed before it reaches breathing air. According to the state of the art, this is done by activated carbon filters. It is known to provide filters with chemical admixtures that react chemically with gases that are contained in the air. For example, sodium bicarbonate can chemically bind acidic air components such as sulfur dioxide.
- the present invention deals with the problem of improving the efficiency of the catalytically active filter system.
- Oxidizable substances (such as C ⁇ Hi ⁇ ) adsorb on surfaces, accumulate to reactive concentrations and, in ideal cases, react with active oxygen to give 8 (CO 2 ) and 8 (H 2 O).
- the reaction takes place in particular on the surface of the sorption catalyst arranged in the flow direction after ozonization, which is usually an activated carbon filter.
- Active oxygen and ozone dissolve in the water stored in the sorption catalyst / filter and form hydrogen peroxide H 2 0 2 and oxygen radicals.
- Oxygen radicals react violently with oxidizable substances and are extremely bactericidal and fungicidal (concentrations of 1-5ppm active oxygen dissolved in water are sufficient).
- the half-life of oxygen radicals stored in the sorption catalyst can be up to a few days. Contamination of the A-carbon filter is reliably prevented and airborne bacteria and germs are destroyed. This is because the chemical oxidation process continues even after the ozone supply has ended.
- Moisture present on the surface forms hydroradicals.
- Intermediate steps stands for the highly radical monatomic oxygen ions, the reactivity of which is once again greater by a factor of 1000 than that for the atomic oxygen ions.
- Germs, protein residues and odor-carrying chemical substances (organic substances) attached to the sorption catalyst are advantageously oxidatively destroyed or denatured.
- the sorption catalyst remains permanently hygienic and olfactory.
- catalytically active substances can be mixed with the activated carbon and can be used together as filter material. It is also possible to have catalytically active on the upstream side of the activated carbon filter Apply material as a layer. Finally, it is possible to apply a layer of the catalytically active material on the outflow side of the activated carbon filter.
- Salts or oxides or compounds of these substances have also been tested as catalytically active, for example
- Non-noble metals are also catalytically active if chemical energy in the form of e.g. Ozone is supplied and the reactions supported:
- Titanium and titanium dioxide have catalytically good properties.
- titanium dioxide (Ti0 2 ) is applied to a suitable carrier as a gas-permeable coating on the outflow side of an activated carbon filter.
- the catalytic activity of titanium dioxide is stimulated by the chemical energy that is inherent in ozone and air ions.
- Oxidizable material such as odor-bearing gases or vapors as well as organic material such as bacteria and viruses are advantageously destroyed on the surface of the catalyst.
- Gases such as nitrogen oxides, sulfur dioxide, phosphorus dioxide and other reducible gases are reduced catalytically.
- the ozone content in the air is reduced to an innocuous minimum. Since the titanium dioxide used in the example works as a catalyst and is not involved in the chemical process itself, there is no wear that shortens the life of the sorption catalyst. Rather, the outflowing air maintains its neutral character.
- FIG. 1 shows an example of a typical air treatment system, such as that used in vehicles, in compact air treatment devices and in building air conditioning systems Commitment comes.
- a pre-filter 1 is shown, which retains dusts and particles.
- the particle filter plays no role in the functional context of this invention.
- an air-promoting blower 2 is shown, which of course can be arranged elsewhere within the functional series.
- the ozone and ion generator 3, which enriches the air with a certain amount of ozone, is also shown. Concentrations between 50-200 ⁇ g / m 3 are typical for applications in the field of air treatment.
- an activated carbon filter 4 is shown, which also serves here as an ozone destroyer and as a simple catalyst and is therefore called “sorption catalyst”.
- FIG. 2 shows an identical structure in principle, but supplemented by the catalyst 5.
- the catalyst 5 in one embodiment of the invention consists of catalytically active material, such as titanium dioxide (TiO 2 ).
- the catalyst can be applied to its own, air-permeable carrier layer and can be attached as a separate component behind the activated carbon sorption catalyst 4.
- the catalyst 5 can also be applied in an adhesive manner on the outflow side of the sorption catalyst 4.
- the catalyst 5 - not shown in the picture - can be contained in the activated carbon sorption catalyst 4 as a mixture of the activated carbon.
- the catalyst 5 can - not shown in the figure - be adhered to the upstream side of the activated carbon sorption catalyst 4 or can be arranged as a separate component on an air-permeable carrier layer in front of the active sorption catalyst.
- the aim is to maximize the depletion of natural ozone and to maximize the useful processes taking place in conjunction with ozone and air constituents and to optimize the service life of the filters.
- activated carbon filters for air treatment tasks of all kinds with catalytically active substances in the sense of the invention presented here, in order to improve the efficiency of the filters compared to oxidizable air components beyond the pure absorption of the activated carbon and to oxygen radicals in the breathing air destroy reliably.
- a catalytically active material for example titanium dioxide
- air conditioning systems which can be located, for example, in buildings, in compact devices or in automobiles.
- a small amount of ozone is added to the airflow that is directed to the evaporators. If ozone comes into contact with the catalyst, the chemical reactions described above intensify. This makes it possible to effectively prevent the known dangerous and unpleasant contamination of the evaporator with the help of gassing with ozone and active oxygen ions in a very low concentration.
- the ozone contained in the supplied air is broken down on the surface of the fumigated evaporator and thus extracted from the air.
- the evaporator itself works here in the function of the sorption catalyst described above.
- climate channels from the inside with, for example, titanium dioxide, because the surfaces of climate channels adsorb air constituents. If small amounts of air ions and / or ozone are introduced into the climate channels at the same time, they will also adsorb on the surfaces.
- the chemical reaction described above sets in and is catalytically strengthened, with the result that the transported air is free of ozone, oxidizable gases and vapors and of bacteria, viruses, fungi and their spores. This would make an important contribution against the so-called "sick building syndrome".
- the invention extends not only to the aforementioned examples, but is used wherever, in the interaction of air, ozone, air ions and air constituents such as gases, vapors, bacteria, viruses, fungi, spores, to improve the efficiency of the reaction mechanisms described in principle is.
