Description

field of invention

The present invention relates to a mobile device for cleaning and disinfecting indoor air.

The present invention also relates to a method for cleaning and disinfecting room air using a mobile device.

Furthermore, the present invention relates in particular to the use of the mobile device for killing microorganisms, specifically viruses and virions, which are collectively referred to below as viruses.

State of the art

Microorganisms are archaea, bacteria, eukaryotes, protists, fungi and green algae. It is still a matter of debate whether viruses or virions should be considered organisms at all. Microorganisms and viruses are the source of a number of serious diseases, epidemics and pandemics such as the current Covid-19 pandemic.

Numerous pesticides such as fungicides, herbicides, insecticides, algaecides, molluscicides, rodenticides, acaricides, and slimicides have been developed to combat the deleterious effects on multicellular humans and plants.

Likewise, numerous antimicrobial agents such as germicides, antibiotics, bactericides, virucides, antifungal agents, antiprotozoal agents and antiparasitic agents have been developed to cure the diseases caused by the microorganisms.

aufgeführt.The constant threat of microorganisms, especially viruses and virions and especially the coronavirus SARS-Co-V2, has created a growing demand for efficient and effective methods for decontamination and disinfection. The "List N: Products with Emerging Viral Pathogens AND Human Coronavirus Claims for Use against SARS-CoV-2, Date Accessed: 05/31/2020 of the EPA lists, US Govt." lists numerous organic and inorganic active compounds such as HOCI, peroxoacetic acid, quaternary ammonium, potassium peroxomonosulphate, chlorine dioxide, hydrogen peroxide, citric acid, lactic acid, dichloroisocyanurate, sodium hypochlorite or ethanol. However, these disinfectants can only be used in cleaning solutions or wiping solutions and have no permanent disinfecting effect.

listed.

However, these active ingredients are low molecular weight compounds, so there is always a risk that they will leach out of the protected materials.

For this reason there have already been numerous attempts to immobilize the disinfecting active ingredients and pharmaceuticals in order to achieve a permanent disinfecting and/or pharmaceutically active surface.

The international patent application discloses this WO 96/39821 A1 Reagents and methods for modifying textiles to inactivate viruses on contact. To do this, the textiles are modified by photochemically immobilizing hydrophilic polymers containing quaternary ammonium groups and hydrocarbon chains, resulting in a surface capable of disrupting lipid-enveloped viruses on contact. However, when these hydrophilic polymers are applied to non-woven fabrics, there is no guarantee that they will be fully crosslinked by the light because portions will necessarily be shaded. As a result, a certain proportion of the polymers always remains soluble.

From the American patent US 5,883,155A produce films of elastomers in which active chemicals such as biocides for medical use are uniformly dispersed in the form of gel inclusions. For example, the elastomeric film contains as active ingredients quaternary ammonium, phthalaldehyde, phenol derivatives, formalin, nonionic surfactants containing at least one polyoxyethylene block, hexamidine, iodine compounds, surface-active substances with a virucidal effect, sodium and potassium dichromate and hydrochlorites. However, these active ingredients are toxic and carcinogenic and are released into the environment.

The American Patent US 6,180,584 B1 discloses disinfectant mixtures with a longer-lasting biocidal effect. The mixtures form an adhesive, transparent, water-insoluble polymer film on the substrate surfaces, which has a longer-lasting antimicrobial disinfecting effect. The effect lasts longer even without a new order. The disinfecting effect of the surface is based on direct contact and the components are not released into a contacting solution in an amount that would disinfect the solution. The active ingredient is a metallic material, particularly silver iodide. However, this salt is sensitive to light, so dark spots will form in the mixture over time.

The American patent application U.S. 2007/0031512 A1 discloses that layered phyllosilicates are capable of adsorbing and/or binding viruses and thus deactivating them. The layered phyllosilicates can be sprayed into the human nostrils or can be included in a face mask to prevent infection. They can be suspended in water intended for skin contact to inactivate the virus, or be part of an HVAC filter that prevents the transfer of viruses from room to room, for example in a hospital. The phyllosilicates can be included in a paper or wipe to deactivate viruses on hospital and operating room furniture and surgical equipment. In addition, the layered phyllosilicates can be used in paints for clean rooms.

The international patent application WO 2007/120509 A2 discloses a mask containing a plurality of layers, the first layer containing an acid or a salt or ester of the acid. The second layer contains a base or a salt or ester of the base. The third layer of the mask contains a metallic germicide selected from the group consisting of zinc, copper, nickel, iodine, manganese, tin, boron, silver and their salts, complexing agents and surfactants. Apparently the third layer in particular contains toxic substances.

The American patent application U.S. 2007/0292486 A1 discloses biocidal polymer nanoparticle/microparticle composites containing an ionic polymer and biocidal metal salts, particularly silver bromide. The silver bromide is evenly distributed in the polymer matrix. It is believed that the biocidal effect is due to silver particles releasing silver ions and bromide ions. In addition, it is believed that the bromide ions make textiles flame retardant. The disadvantages of these composites are the high price of silver bromide, the sensitivity of the salt to light, which causes dark discolorations in the composite layers, and the leaching of toxic silver ions. In addition, the biocidal metal salts are not concentrated on the surface of the composites, so most of the metal salts do not come into contact with the microorganisms.

The international patent application WO 2008/127416 A2 discloses hydrophobic polymeric coatings that can be applied non-covalently to solid surfaces of metals, plastics, glass, polymers, textiles and other substrates such as fabrics, gauze, bandages, cloths and fibers in the same manner as paints by brushing, spraying or dipping to biocide the surfaces or to make bactericidal. The hydrophobic polymers contain quaternary ammonium groups with long chain aliphatic groups containing more than 10 carbon atoms. However, the hydrophobic polymers can be damaged by organic solvents and even completely removed from the surfaces.

The American patent application U.S. 2009/0081249 A1 discloses antimicrobial compositions containing two or more antiviral agents covalently linked to a polymer. Suitable antiviral agents are sialic acid, zanamivir, oseltamivir, amantadine and rimantadine. The polymer is preferably water-soluble such as poly(isobutylene-alt-maleic anhydride), polyaspartic acid, poly(1-glutamic acid), chitosan, carboxymethyl cellulose, carboxymethyl dextran or polyethyleneimine. The compositions can be formulated for enteral or parenteral administration. However, the antimicrobial compositions are difficult to produce on an industrial scale.

The American patent application U.S. 2009/0320849 A1 discloses a face mask containing a filter material made from a fibrous substrate. Its fibers contain, on their surface, in particular a fleece made of polypropylene or polyester, which contains an acidic polymer, in particular of the polycarboxylic acid type. The face mask has an antiviral effect against inhaled or exhaled air. However, since the polycarboxylic acids, such as polyacrylic acid, are water-soluble, they can be corroded by aqueous aerosols

The American patent application U.S. 2012/0016055 A1 discloses biocidal coating compositions containing a biocide and nonionic polymers and solvents. The coating compositions form clear and non-tacky films and surfaces, but because of their solubility they can be easily removed.

The American patent application U.S. 2013/0344122 A1 discloses medical articles with antimicrobial properties and good barrier properties. The medical articles contain non-woven fabrics made of polypropylene and a coating containing chlorhexidine acetate and trichlosan. For example, these pharmaceuticals are dissolved in ethanol and sprayed onto the tissue until it is evenly saturated. The fabric samples are then dried. The medical articles can be gowns, shoe covers, drapes, wraps, caps, lab coats, and face masks. The disadvantage of these medical articles is that the pharmaceuticals are not firmly bound to the fibers of the non-woven material and can easily be dusted off or washed away by solvents.

The international patent application WO 2014/149321 A1 discloses a coating with a reactive surface that has disinfectant and biocidal properties. The reactive compositions are renewable or "rechargeable" through the reapplication of the active component and do not need to be removed, discarded, or replaced. The reactive composition includes a hygroscopic polymer film, such as crosslinked polyvinylpyrrolidone, which has been treated with a liquid or gaseous oxidizing agent, such as hydrogen peroxide, chlorine, peracetic acid, iodine, or mixtures thereof, long enough for the oxidizing agent to react with or be absorbed into the polymer film. The disadvantages of these reactive surface coatings are that they must be activated with toxic and corrosive or gaseous oxidants, which oxidants are then released from the coatings.

The American patent application U.S. 2014/0127517 A1 discloses films of linear or branched polyethylene cores having antiviral properties. These films are covalently bound to surfaces and quaternized with hydrophobic side chains and modified with groups crosslinkable with actinic radiation. The disadvantages of these films are that the polyethyleneimines have to be modified by polymer-analogous reactions. After their application to surfaces, they must be irradiated with UV light. However, if they are applied to non-woven materials, it cannot be guaranteed that all of the modified polyethylenimine will be reached and crosslinked by the UV radiation.

The international patent application WO 2016/116259 A1 discloses biocidal materials containing an organic polymer matrix or an inorganic ceramic matrix in which biocidal polyoxometalates are inhomogeneously distributed. The concentration of the polyoxometalates on the surface of the matrices can be higher than on the inside.

The American patent application US 2017/0275472 A1 discloses surface coating antimicrobial coating materials containing (i) biocides such as chlorine dioxide, hydrogen peroxide, peroxyacids, alcohols, essential oils, antimicrobial components of essential oils, bleaches, antibiotics, Phytochemicals and mixtures thereof, (ii) inorganic-organic hollow bodies permeable to biocides, wherein the inorganic materials are metal oxides, metal complexes, metal salts, metal particles and mixtures thereof and the organic materials are non-ionic polymers such as polyethylene glycol or polyvinylpyrrolidone. The antimicrobial coating material is believed to have durable and versatile antimicrobial activity at high temperatures through contact kill, release, non-stick, and self-cleaning. The disadvantage is that volatile biocides are used, which are permanently released from the coating materials.

The American Patent US 10,227,495 B2 claims biocidal biopolymer coatings made from crosslinked functionalized triglycerides and covalently bonded quaternary ammonium compounds. Crosslinking can take place by irradiation with actinic light or by polyisocyanates. The disadvantage is that the biocidal effect is limited to the use of one class of compounds, namely quaternary ammonium compounds.

Since the start of the SARS-Co-V2 pandemic, numerous attempts have been made to develop new methods and materials to prevent the spread of the virus.

Thus, A.J. Galante et al. from the Department of Industrial Engineering, University of Pittsburgh, and The Department of Ophthalmology, Charles T. Campbell Laboratory of Ophthalmic Microbiology, University of Pittsburgh, School of Medicine, superhemophobic anti-virofouling coatings for medical apparel (see also: SpecialChem, The material selection platform, Coating Ingredients, "Researchers Create New Washable, Textile, Coating the Can Repel Viruses.", Published on 2020-05-26"; and "New coating could improve medical gear by making the coronavirus slide right off."; https ://www.zmescience.com/science/news-science/coating-personal-protection-equipment-252342/) The tough, multilayer coatings are made by sintering polytetrafluoroethylene (PTFE) nanoparticles in a solvent onto polypropylene microfibers The disadvantage is that their production requires a lot of energy and solvents, expensive PTFE and they do not kill the viruses.

Researchers from Ben Gurion University, Israel, have developed coatings based on nanoparticles to prevent the spread of the coronavirus. They have found that copper nanoparticles are the most effective in this regard. The antiviral coatings can be brushed or sprayed onto surfaces. Conventional and known polymers containing nanoparticles of copper can be used. The nanoparticles enable the controlled release of metal ions onto the coated surfaces (see also SpecialChem, The material selection platform, Coating Ingredients, published on 2020-05-21). However, the copper nanoparticles and the copper ions are not only toxic for microorganisms and viruses, but also for higher animals and humans.

Bio-Fence, Inc., Israel, has developed new antimicrobial coatings intended to provide durable protection against coronavirus. Apparently the coatings contain a polymer comprising active chlorine that can be replenished by hydrochlorite solutions (see SpecialChem, The material selection platform, Coating Ingredients, published on 2020-05-12). The disadvantage of these coatings is the use of corrosive hypochlorite and active chlorine presumably bound to nitrogen atoms in the form of >N-Cl groups. Thus, these materials are toxic and have an intense unpleasant odor.

Yet another approach is being pursued by researchers at the University Hospitals of the University of Regensburg, Germany, by the company TriOptoTec. (See "SpecialChem" June 29, 2020:

The paint in question apparently contains dioctyl sodium sulfosuccinate in butyl diglycol. It also contains 10H-Benzo[G]pteridine-2,4-dione derivatives (cf. American patents U.S. 10,227,348 B2 and U.S. 9,796,715 B2 ) or phenalen-1-one derivatives (cf. the American patent U.S. 9,302,004 B2 ) as photosensitizers. The varnish is mainly applied to paper or cardboard. When exposed to visible light, the photosensitizer produces singlet oxygen that kills the microorganisms on the surface of the paper or board. The disadvantage is that this reaction only takes place in the light and not in the shade, so that numerous applications are ruled out.

In the field of surface technology, it is generally known that a particularly strong lotus effect or super hydrophobicity can be achieved through a hierarchically structured surface design. This is what the American patent application discloses US 2014/0238646 A1 describe a method for the fabrication of hierarchically arranged structures of nanoscale inorganic phosphate particles homogeneously distributed on the surface of micrometer-scale phyllosilicate particles. Because these surfaces are not wetted and condensed moisture immediately forms droplets that roll off the surfaces, the contact time is too short for a biocidal or virucidal effect.

Jinghzi Pu et al. mask filter developed by the School of Science at IUBUI, Iniana, USA, which mimics the internal structure of fish gills. The complex structures are produced by 3D printing and subsequent coating of the surface with copper by electroplating. By increasing the surface area over which the air passes, the biocidal effect of the copper is said to increase. The developers speculate that these structures could also be suitable for filters for air conditioning systems in buildings and airplanes (see SpecialChem, Industry News, Researchers Use Cu Coating on Plastic Mask Filters to Reduce Virus Spread, Publ.

However, it is to be feared that these complex structures will generate intense noises such as hissing or whistling if there is a high air throughput with high flow velocities.

Air purifiers are mobile devices for cleaning air using filters. According to their separation efficiency, the filters can be

• - High-performance particle filter (EPA = Efficient Particulate Air filter), smallest filterable particle size: 100 nm,
• - Particle filter (HEPA = High Efficiency Particulate Air filter), smallest filterable particle size: 100 nm,
• - High-performance particulate filter (ULPA = Ultra Low Penetration Air filter), smallest filterable particle size: 50 nm,
• - Medium filter, smallest filterable particle size: 300 nm,
• - Pre-filter, smallest filterable particle size: 1000 nm, and
• - Automobile cabin filters, smallest filterable particle size: 500 nm. There are therefore no filters available for the range from 1 nm to 50 nm.

• - Diffusionseffekt: Sehr kleine Partikel (Partikelgröße: 50 nm bis 100 nm) folgen nicht dem Gasstrom, sondern haben durch ihre Zusammenstöße mit den Gasmolekülen einer der Brownschen Bewegung ähnliche Flugbahn und stoßen dadurch mit den Filterfasern zusammen, woran sie haften bleiben. Dieser Effekt wird auch als Diffusionscharakteristik (diffusion regime) bezeichnet.
• - Sperreffekt: Kleinere Partikel (Partikelgröße: 100 nm bis 500 nm), die dem Gasstrom um die Faser folgen, bleiben haften, wenn sie der Filterphase zu nahekommen. Dieser Effekt wird auch als Abfangcharakteristik (interception regime) bezeichnet.
• - Trägheitseffekt: Größere Partikel (Partikelgröße: 500 nm bis >1 µm) folgen nicht dem Gasstrom um die Faser, sondern prallen aufgrund ihrer Trägheit dagegen und bleiben daran haften. Dieser Effekt wird auch als inerte Einschlags- und Abfangcharakteristik (inertial impaction regime) bezeichnet.

Depending on the particle size, their filter effect is based on the following effects:

• - Diffusion effect: Very small particles (particle size: 50 nm to 100 nm) do not follow the gas flow, but have a trajectory similar to Brownian movement due to their collisions with the gas molecules and thus collide with the filter fibers, to which they adhere. This effect is also known as the diffusion regime.
• - Barrier effect: Smaller particles (particle size: 100 nm to 500 nm) following the gas flow around the fiber will stick if they get too close to the filter phase. This effect is also known as the interception regime.
• - Effect of inertia: Larger particles (particle size: 500 nm to >1 µm) do not follow the gas flow around the fiber but, due to their inertia, collide against it and stick to it. This effect is also referred to as the inertial impaction regime.

In the particle size range from 100 nm to 500 nm, the diffusion effect and the blocking effect occur together. In the particle size range from 500 nm to >1 µm, the inertia effect and the blocking effect also occur together.

According to the filter effects, particles with a particle size of 200 nm to 400 nm are the most difficult to separate. They are also referred to as MMPS = most penetrating particle size. The filter efficiency drops to 50% in this size range. Larger and smaller particles are better separated due to their physical properties.

EPA, HEPA and UPLA are classified according to their effectiveness for these grain sizes using a test aerosol of di-2-ethylhexyl sebacate (DEHS). K.W. Lee and B.Y.H. Liu give formulas in their article "On the Minimum Efficiency and the Most Penetrating Particle Size for Fibrous Filters" in Journal of the Air Pollution Control Association, Vol. 30, No. 4, April 1980, pages 377-381 which allow to calculate the minimum efficiency and MMPS for fiber filters due to the diffusion effect and the inertial effect. The results show that MMPS decreases with increasing filtration speed and fiber volume fraction and increases with increasing fiber size.

However, the fact that there are no filters for nanoparticles with an average particle size d ₅₀ of 1 nm to <50 nm is also particularly critical. Ironically, these particles are easily deposited in the bronchi and alveoli and generally have the highest mortality and toxicity. They can therefore cause diseases such as asthma, bronchitis, arteriosclerosis, arrhythmia, dermatitis, autoimmune diseases, cancer, Crohn's disease or organ failure.

This is particularly critical since the depth filters or HEPA filters are used in medical areas such as operating rooms, intensive care units and laboratories, as well as in clean rooms, in nuclear technology and in air washers.

Another technology that is problematic in this respect is electrostatic precipitators for electric gas cleaning, electric dust filters or electrostatic stats, which are based on the separation of particles from gases using the electrostatic principle. Separation in the electrostatic precipitator can take place in five separate phases:

1. 1. Release of electrical charges, mostly electrons,
2. 2. charging of the dust particles in the electric field or ionizer,
3. 3. Transport of the charged dust particles to the collecting electrode
4. 4. Adherence of the dust particles to the collecting electrode and
5. 5. Removal of the dust layer from the collecting electrode.

However, it is not possible to completely separate particles in the nanometer range, so that there is a risk of contamination with respirable particles in the vicinity of such systems.

These electric dust filters are often used in exhaust gas treatment. Amines, carbon dioxide, ammonia, hydrochloric acid, hydrogen sulfide and other toxic gases are removed from the exhaust gas flow using membranes. Since the electrostatic accumulation filters cannot completely remove the finest particles, they damage the membranes and reduce their separation efficiency.

For details regarding the toxicology, see the review articles by Günter Oberdörster, Eva Oberdörster and Jan Oberdörster, “Nanotoxicology. An Emerging Discipline Evolving from Studies of Ultrafine Particles”, in Environmental Health Perspectives Volume 113. (7), 2005, 823-839, and Günter Oberdörster, Vicki Stone and Ken Donaldson, “Toxicology of nanoparticles: A historical perspective”, Nanotoxicology, March 2007; 1(1): 2-25, referenced.

Viruses present outside of cells are scientifically called virions. They have a diameter of 15 nm to 440 nm and are significantly smaller than bacteria, most of which have a diameter of 1 µm to 5 µm. The viruses or virions thus have sizes that fall within the "filter gaps" of 1 nm to 50 nm and 200 nm to 400 nm.

Therefore, the air purifiers equipped with filters can at best reduce the concentration of viruses or virions in the indoor air, but they cannot completely remove or destroy them because of the lack of a disinfecting effect.

Non-sedimenting aerosols generated by humans and animals, particularly aerosols created by breathing, coughing or sneezing and which disperse very rapidly in large volumes in enclosed spaces, play a central role in the transmission of viruses from human to human, from animal to animal Human, animal to animal and human to animal. They contribute significantly to the spread of diseases. Since the non-sedimenting aerosols generally have a particle diameter of 0.1 nm to 100 nm, they can only be intercepted incompletely - if at all - by the air filters.

If you want to keep the concentration of viruses and virions in the air in closed rooms below a threshold above which there is a high risk of infection, the air must be constantly circulated in large quantities. However, this currently only works with stationary air conditioning systems, which often cannot be retrofitted to buildings, means of transport, etc. Another disadvantage is that powerful air conditioners, blowers and mobile air purifiers often make a loud noise, which is perceived as annoying. Their particularly strong air currents often cause health problems such as colds and joint pain.

• „Luftreiniger gegen Viren & Bakterien - auch gegen den Coronavirus? Ein Luftreiniger gegen Bakterien und Viren ist besonders sinnvoll für Warteräume von Arztpraxen, für Büros oder Pakete, für andere öffentliche Räume wie Kantinen, Friseursalons oder Nagelstudios. Überall dort, wo Menschen zusammenkommen und die Luft mehr oder weniger steht, steigt nämlich die Ansteckungsgefahr, die durch den Einsatz von Luftreinigern gesenkt werden kann. Ob Luftreiniger auch konkret gegen den Covid 19 Coronavirus wirken, ist aufgrund dessen, dass es Ihn noch nicht lange gibt noch nicht getestet worden. Da es kein komplett neuer Virus ist, sondern eine mutierte Form bereits bekannter Viren, spricht jedoch sehr viel für eine Wirksamkeit.
• Welche Luftreiniger besonders gut gegen Bakterien und Viren geeignet sind, erfahren Sie weiter unten.
• WICHTIGER HINWEIS: Bitte beachten Sie, dass Luftreiniger zwar die Konzentration von Viren und Bakterien in der Luft erheblich reduzieren, jedoch nicht komplett verhindern können. Der beste Schutz vor dem Coronavirus ist die Meidung sozialer Kontakte sowie häufiges und gründliches Händewaschen. Bitte leisten Sie in jedem Fall den Auflagen der Bundes- und Landesregierungen folge.
• „Aufgrund der geringen Größe von Bakterien und Viren müssen Luftreiniger über die richtigen Filter verfügen, um schwebende Gefahren aus der Luft sicher einfangen zu können. Luftreiniger mit HEPA-Filter arbeiten sehr effektiv gegen mikroskopisch kleine Infektionsherde und filtern auch besonders winzige Bakterien mit einer Partikelgröße von nur 0,3 Mikrometer (pm) sicher aus der Raumluft. Zusätzliche Methoden wie photokatalytische Filter, Nano-Silber-Filter oder zugeschaltete Ionisatoren können dabei helfen, den Wirkungsgrad von Luftreinigern noch weiter zu verbessern. Um Bakterien und Viren möglichst schnell in die verfügbaren Filter einzufangen ist auch ein hoher Luftdurchsatz bei Luftreinigern wichtig. Ein Luftreiniger sollte in der Lage sein, die komplette Raumluft mindestens zwei Mal pro Stunde zu reinigen. Hersteller von Premium Geräten visieren eine komplette Reinigung der Raumluft bis zu 5 Mal pro Stunde an.“

• "Air purifier against viruses & bacteria - also against the corona virus? An air purifier against bacteria and viruses is particularly useful for waiting rooms in medical practices, for Offices or packages, for other public spaces such as canteens, hair salons or nail salons. Wherever people come together and the air is more or less still, the risk of infection increases, which can be reduced by using air purifiers. Whether air purifiers also work specifically against the Covid 19 corona virus has not yet been tested due to the fact that it has not been around for long. Since it is not a completely new virus, but a mutated form of already known viruses, there is a lot to be said for its effectiveness.
• You can find out below which air purifiers are particularly suitable against bacteria and viruses.
• IMPORTANT NOTE: Please note that while air purifiers can significantly reduce the concentration of viruses and bacteria in the air, they cannot prevent them completely. The best protection against the corona virus is avoiding social contacts and washing your hands frequently and thoroughly. In any case, please follow the requirements of the federal and state governments.
• “Due to the small size of bacteria and viruses, air purifiers must have the right filters to safely capture airborne hazards. Air purifiers with HEPA filters work very effectively against microscopic sources of infection and also reliably filter particularly tiny bacteria with a particle size of just 0.3 micrometers (pm) from the room air. Additional methods such as photocatalytic filters, nano-silver filters or switched-on ionizers can help to further improve the efficiency of air purifiers. In order to catch bacteria and viruses as quickly as possible in the available filters, a high air flow rate is also important for air purifiers. An air purifier should be able to clean the entire room air at least twice an hour. Manufacturers of premium devices are targeting a complete cleaning of the room air up to 5 times per hour.”

(End of original quote).

Another way to reduce the concentration of virions and aerosols in closed rooms is intensive forced ventilation with outside air. On the one hand, this presupposes that the rooms are on the outside of buildings so that such ventilation options are available at all and, if so, that the weather conditions permit ventilation. This is likely to be difficult at low outside temperatures, driving rain, thunderstorms, hail, snow, freezing rain, etc.

the WO 94/06296 A1 discloses a cartridge for air purification or disinfection in an air flow with a cartridge base and different biocidal beds, each of which is separated from one another by a sieve base, with a first bed of an iodized resin (as a disinfectant) and a second bed of an activated carbon (as an adsorbent ) are provided.

the AU2011221409A1 shows filter cartridges with several chambers and sieve trays as well as a circumferential flange for attachment to mobile devices with fans for air purification. For the filling of the various filter stages, for example, the following are provided: a bed of biocidal microcapsules, a fiber filter with activated carbon or activated carbon particles (as an absorbent), the activated carbon filter stage being arranged in the flow direction just behind the biocidal filter stage.

From the DE 10 2015 104 354 B4 DE 298 16 225 U1 and DE 299 05 469 U1 test devices for air cleaning devices are known.

Object of the present invention

The present invention was based on the object of proposing a low-noise, mobile device for cleaning and disinfecting room air, which no longer has the disadvantages of the prior art, but allows contaminated room air to be permanently freed from a wide variety of noxae and microorganisms . In particular, the mobile device bacteria and / or viruses and aerosols contaminated by bacteria and / or viruses, especially SARS-Co-V2 viruses and by SARS-Co-V2 viruses contaminated aerosols, and absorb and/or adsorb the resulting decomposition products.

This is also intended to ensure that the volume of air that has to be circulated in order to achieve a lasting effect can be significantly reduced. This should also reduce energy consumption in the long term. Overall, an optimal balance should be achieved between the air volume to be circulated, the contact time of the viruses and bacteria with the biocides and the size of the devices.

Furthermore, the devices should be easy to produce and only contain bactericidal and virucidal substances that are officially approved for these purposes.

In addition, the devices should not emit any dust, vapors or aerosols into the cleaned and disinfected room air.

The solution according to the invention

Accordingly, the mobile device for cleaning and disinfecting indoor air according to independent patent claim 1 was found, which is referred to below as "the device according to the invention". Advantageous embodiments of the device according to the invention are the subject matter of dependent claims 2 to 10.

In addition, the method for cleaning and disinfecting room air using the device according to the invention according to claim 11 was found. The method is referred to below as the “method according to the invention”.

Furthermore, the use of the device according to the invention and the method according to the invention for the elimination of free or aerosol-bound bacteria, viruses and other noxae in the air according to independent patent claim 12 was found. This use is referred to below as “use according to the invention”.

Last but not least, the test device according to the invention was found according to independent patent claim 13 for testing the effectiveness of the device according to the invention.

Advantages of the Invention

In view of the prior art, it was surprising and unforeseeable for the person skilled in the art that the object on which the present invention is based could be achieved with the aid of the device according to the invention, the method according to the invention and the use according to the invention.

In particular, it was surprising that the device according to the invention no longer had the disadvantages of the prior art, but instead allowed contaminated room air to be permanently freed from a wide variety of noxae and microorganisms. In particular, using the device according to the invention and the method according to the invention, bacteria and viruses and aerosols contaminated by bacteria and/or viruses, specifically SARS-Co-V2 viruses and aerosols contaminated by SARS-Co-V2 viruses, could be eliminated by contact and the resulting Decay products are absorbed and / or adsorbed.

This also made it possible to significantly reduce the volume of air that had to be circulated in order to achieve a lasting effect. This also resulted in a sustained reduction in energy consumption. Overall, an optimal balance was achieved between the volume of air to be circulated, the contact time of the viruses and bacteria with the biocides and the size of the devices.

Furthermore, the device according to the invention could be manufactured and operated automatically in a simple manner and contained only bactericidal and virucidal substances that are also officially approved for these purposes. In addition, the free surfaces of all components of the device according to the invention could also be provided with a coating with a permanent virucidal and bactericidal effect, which advantageously further increased the overall effect.

In addition, the device according to the invention did not release any dust, vapors or aerosols into the cleaned and disinfected room air.

The device according to the invention and the method according to the invention could be used in a wide variety of closed rooms, with their mobility proving to be a further particular advantage.

Another essential advantage of the device according to the invention was that used virucidal and/or bactericidal adsorbents and absorbents could be decontaminated in a simple manner directly by mechanochemical processes in which harmful organic waste products were converted into carbon. The same applied to the plastic parts, which only deviated from the specified specifications after a surprisingly long period of use.

Because of their significantly smaller dimensions and smaller space requirements compared to fans with filters or electrostatic fans, the devices according to the invention are particularly well suited to cleaning and decontaminating the room air in the corners of rooms without making a sound or almost without making a sound. Therefore, they can also be used particularly well in classrooms or conference rooms, where loudly noisy fans are particularly annoying.

Further advantages of the invention appear from the following description.

Detailed Description of the Invention

The device according to the invention is used to clean and disinfect the air in rooms of all kinds. In particular, it is used to eliminate free bacteria or bacteria, viruses and other noxae bound to aerosols in the air of living rooms, sick rooms, operating theaters, treatment rooms in doctor's offices and physiotherapy facilities, laboratories of all kinds, pubs, restaurants, bistros, hotel rooms, classrooms, classrooms, fitness centers, trains, cars, buses, taxis, caravans, mobile homes, camping tents, airplanes, ship cabins, offices, conference rooms, meeting rooms, theaters, cinemas, ship terminals, train stations, airport terminals , elevators, workshops, factory buildings, sports halls, moving rooms, stairwells and shops of all kinds.

The device according to the invention comprises the components and embodiments described below.

In an advantageous embodiment of the device according to the invention, the surfaces of the components, in particular the surfaces that come into contact with air, are provided with at least one of the bactericidal and/or virucidal coatings described below.

The device according to the invention has a vertical, tubular outer wall with a horizontal base area and a standing base as well as an upper circular opening. The horizontal cross-section or perimeter of the vertical tubular outer wall is circular.

The diameter of the tubular outer wall and thus of the device according to the invention can vary widely and depends primarily on the volume of air that is to be decontaminated. The diameter is preferably 5 cm to 50 cm. The wall thickness is preferably 0.2 cm to 2 cm, particularly preferably 0.3 cm to 1.5 cm and in particular 0.5 cm to 1 cm.

The height of the tubular outer wall and thus of the device according to the invention can also vary widely and depends primarily on the volume of air that is to be decontaminated. The height is preferably 30 cm to 300 cm, preferably 50 cm to 300 cm and in particular 60 cm to 300 cm.

The outer wall is made of a wide variety of materials. These materials are preferably selected from the group consisting of polished, roughened, decorated, painted, provided with reliefs and gemstones and/or mosaics, coated with clear lacquer and/or provided with sound-absorbing coatings sandstones, solid woods, granites, basalts, marble, artificial stones Glasses, steels, aluminum, plastics, glass fiber reinforced plastics, textile fiber reinforced plastics and plastics reinforced with fillers.

Suitable plastics are customary and known linear and/or branched and/or block, comb and/or random polyaddition resins, polycondensation resins and/or (co)polymers of ethylenically unsaturated monomers.

Examples of suitable (co)polymers are (meth)acrylate (co)polymers and/or polystyrene, polyvinyl esters, polyvinyl ethers, polyvinyl halides, polyvinylamides, polyacrylonitriles, polyethylenes, polypropylenes, polybutylenes, polyisoprenes and/or their copolymers.

Examples of suitable polyaddition resins or polycondensation resins are polyesters, alkyds, polylactones, polycarbonates, polyethers, proteins, epoxy resin-amine adducts, polyurethanes, alkyd resins, polysiloxanes, phenol-formaldehyde resins, urea-formaldehyde resins, melamine-formaldehyde resins, cellulose, polysulfides , polyacetals, polyethylene oxides, polycaprolactams, polylactones, polylactides, polyimides, and/or polyureas.

As is known, thermosets are produced from multifunctional, low molecular weight and/or oligomeric compounds by (co)polymerization initiated thermally and/or with actinic radiation.

The plastics can contain customary and known reinforcing fibers and fillers.

Examples of suitable hardwoods are beech, oak and ash.

Examples of suitable glasses are in Rompp-Online under the keywords "glass", "hard glass" or "safety glass" or in the German translation of the European patent EP 0 847 965 B1 with the case number DE 697 312 168 T2 , page 8, paragraph [0053]. Examples of particularly suitable glasses are non-tempered, partially tempered and tempered float glass, cast glass or ceramic glass.

The vertical, tubular outer wall has at least one circumferential separation point and preferably two circumferential separation points at which or at which the outer wall can be disassembled and reassembled. These separation points can be plug connections, bayonet connections, flange connections or screw connections. The separation points facilitate assembly and maintenance of the device according to the invention.

The device according to the invention has a tubular interior with a vertical arrangement of at least two, preferably at least three, preferably at least four, particularly preferably at least five and in particular at least six pairs of two counter-rotating impellers each with biocidal coatings. The pairs are arranged one above the other at a fixed distance and are mounted for rotation about a central axis of rotation with a circular circumference. Each impeller comprises at least two, preferably at least three, preferably at least four, particularly preferably at least five and in particular at least six impeller blades attached to an impeller hub, two of which face each other so that no imbalance occurs when the impeller rotates. The impeller hubs and the impeller blades are each preferably made in one piece. The blades within a pair of impellers are each inclined and/or shaped such that they counter-rotate along the axis of rotation with air in opposite directions during vertical flow. The wing blades can also have the form of so-called whispering wings, such as those in the European patent EP 1953083 B1 to be discribed.

The running surfaces of the rotating impeller hubs are dry lubricated.

This is preferably achieved by the impeller hubs being made of at least one plastic which, with dry lubrication, has a coefficient of sliding friction µSliding against hardened and ground steel at 23 °C and 50% humidity, a contact pressure of P = 0.05 MPa (0.5 bar ), a speed of v = 0.6 m/s (21.6 km/h) and a temperature near the tread of t = 60 °C from 0.01 to 0.5. Examples of suitable plastics are polyamide 6, polyamide 66, polyamide 12, polyacetal copolymer POM-C, polyethylene terephthalate PET, polytetrafluoroethylene PTFE, polyvinylidene difluoride PVDF, polypropylene PP, polyvinyl chloride PVC, polyetheretherketone PEEK and polysulfone PSU.

All blades are preferably made of one and the same plastic.

The impellers can be easily manufactured by 3D printing, injection molding or machining from raw shapes.

The arrangement has the particular advantage that, due to the counter-rotating rotations, the torques cancel each other out, so that this arrangement stabilizes itself.

The impellers have a fixed, continuous, central axis of rotation made of, for example, sterilizable thermoplastic high-performance plastics, unalloyed steel, high-alloy steel, low-alloy, ferritic steel or chromium steel, with a lower bearing and an upper bearing. The continuous axis of rotation is preferably a hollow tube because this is lighter and has better flexural rigidity than a solid rod. The lower bearing is made of at least one of the materials described above and is attached to the inside of the vertical tubular wall with at least one symmetrically arranged, lateral, horizontal anchorage. The upper bearing is also attached to the inside of the vertical tubular wall with at least one symmetrically arranged lateral horizontal anchorage.

In a further embodiment, the central, vertical axis of rotation is made of corresponding complementary components, in particular made of stainless steel. The components can be solid and/or hollow.

Die Lüfter sind vorzugsweise mit einer horizontal umlaufenden Halterung an der Innenseite der vertikalen rohrförmigen Wand befestigt.Below the lower bearing of the axis of rotation and its anchorage is an axially arranged counter-rotating fan driven by an electric motor. Fans of this type are known and are characterized by a high delivery rate and efficiency. Examples of suitable fans are the CR 6300 N from ebmpapst or the counter-rotating fans from Sanyo Denki (cf.:

downloaded on 9/28/2020). The counter-rotating fans that are optimal for the respective individual case are therefore available to the person skilled in the art. The fans are preferably attached to the inside of the vertical tubular wall with a horizontal circumferential bracket.

At the bottom edge of the fans, i. H. on the suction side, there are horizontal or sloping air baffles running down to the inside of the vertical tubular wall, which guide the air flowing through the air inlet pipes into the suction space below the fans to the suction side. Preferably, there is also a centrally arranged air guide cone on the horizontal floor of the intake chamber.

The at least two or preferably at least three, preferably at least four and in particular at least five air inlet pipes can have different cross sections. Thus, the cross-section can be circular, elliptical, oval, rectangular, square, or columnar. The at least two air pipes can run straight or curved, so that the air enters the intake chamber tangentially, as a result of which vortices are formed in the inflowing contaminated air, which promote mixing. The clear width of the cross section can expand in a funnel shape from the inlet to the outlet. For better air guidance towards the inlet of the at least two air inlet pipes, the outer wall can have correspondingly shaped air guiding grooves. The walls of the at least two air inlet pipes can be constructed from a wide variety of materials, with the materials described above preferably being considered.

A rechargeable battery and an electronic control unit are inserted in the horizontal floor area of the outer wall. The electronic control unit is connected by signal lines to a miniature anemometer located centrally in the top opening of the vertical tubular wall. The electronic control unit processes the measurement signals received and automatically or manually regulates the speed of the fans and the air flow through the device according to the invention.

To create a suction effect, an appropriately dimensioned attachment made of plastic in the form of a venturi tube or an inverted funnel with a funnel tube, funnel handle and funnel truncated cone with plug connections located on the bottom edge of the funnel can be attached to the circular upper end of the outer wall of the device according to the invention. Additional air is drawn in through the air inlets located between the plug connections. However, the plug-in connection can also be a circumferential ring which fits into the complementary recess in the upper end of the outer wall is plugged. This eliminates the lateral supply of air. The inside of the attachment can also be coated with at least one biocidal coating.

Instead of this essay or in addition to this usual and known, air-permeable filter can be present in or above the upper horizontal opening of the outer wall. Their tissue can also be coated with biocidal coatings.

The biocidal coatings to be used according to the invention on the free surfaces of the components made of metals and non-metals can consist of at least one physically, thermally, with actinic radiation or thermally and with actinic radiation (dual cure) curable, liquid or solid coating material in the (i) at least one Biocide as such is dissolved and/or suspended and/or emulsified in a molecularly disperse manner and/or in which (ii) the at least one biocide is supported on at least one particulate carrier material with an average particle size determined by sieve analysis of 500 nm to 1000 μm and is suspended in this form , getting produced.

Biocidal coatings on the exposed surfaces of non-metal components can also consist of biocidal metal layers, island-like metal layers and/or metal particles deposited using Twin-wire Arc Spraying (TWAS), Chemical Vapor Deposition (CVD) , sputtering, cold spray coating and electroless plating.

Furthermore, the biocidal coatings on the free surfaces of the metal and non-metal components can be applied by spraying on solid biocidal microparticles with an average particle size determined by sieve analysis of 500 nm to 1000 μm and/or by spraying on with solid and/or liquid biocides loaded, particulate carrier materials with an average particle size determined by sieve analysis of 500 nm to 1000 μm on uncured layers of coating materials and/or adhesives and subsequent curing. As a result, the biocides and/or the supported biocides are fixed to the surfaces of the coatings so that they form easily accessible biocidal centers.

It is advantageous for contact elimination if the biocidal coatings have a micro-roughness of N4 to N12 according to ISO.

In addition, it is advantageous for contact elimination if the biocidal coatings have a contact angle θ with water of ≤90°, as a result of which wetting and thus the contact times of the contaminated aerosols are extended.

Carrier materials for the biocides are, for example, silicates.

• - Inselsilikate
• - Gruppensilikate
• - Ringsilikate
• - Ketten- und Bandsilikate
• - Übergangsstrukturen zwischen Ketten- und Schichtsilikaten
• - Schichtsilikate
• - Gerüstsilikate

Due to their structural peculiarity, phyllosilicates are preferably used or at least used as well. The elemental composition and the structure of the layered silicate microparticles can vary widely. For example, the classification of silicates into the following structures is known:

• - Island silicates
• - group silicates
• - ring silicates
• - chain and ribbon silicates
• - Transitional structures between chain and sheet silicates
• - layered silicates
• - tectosilicates

Layered silicates are silicates whose silicate cations consist of layers of corner-sharing SiO ₄ tetrahedra. These layers and/or double layers are not further linked to one another. The technically important clay minerals that are widespread in sedimentary rock are also phyllosilicates. The layered structure of these minerals determines the shape and properties of the crystals. They are mostly tabular to laminar with good to perfect cleavage parallel to the layers. The number of rings from which composition of the silicate layers often determines the symmetry and shape of the crystals. Water molecules, large cations and/or lipids can be stored between the layers.

The phyllosilicates are listed in Table 1 below by way of example and not exhaustively. The person skilled in the art can easily select further phyllosilicates that are particularly well suited for the respective individual case.

a) cf. Mineralienatlas, mineral class VIII/H - sheet silicates (phyllosilicates), Strunz 8 systematics

Very particular preference is given to using bentonite from the group of montmorillonites ((Na,Ca) _0.3 (Al,Mg) ₂ Si ₄ O ₁₀ (OH) ₂ .nH ₂ O). Bentonite is a mixture of different clay minerals and contains montmorillonite as the most important component.

Other suitable carrier materials are sclerites and skeletons of diatoms, radiolarians, starfish, corals and sponges.

However, the phyllosilicates described above are not only suitable as carrier materials, but also outstandingly suitable as absorbents and/or absorbents and/or biocides.

Further examples of suitable carrier materials can be from the group consisting of spheres, hollow spheres, shards, granules, ground lumps, shards and granules, pellets, rings, spheres with core-shell structures, ellipsoids, cubes, cuboids, pyramids, cones, cylinders , rhomboids, dodecahedrons, truncated dodecahedrons, icosahedrons, truncated icosahedrons, dumbbells, tori, platelets, needles with circular, oval, elliptical, square, triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal or star-shaped cross-sections, in at least one direction of space curved shards, rings, dumbbells, tori, needles and plates of phyllosilicates, cellular glass, cellular glass gravel, pumice stones, zeolites, expanded clay, expanded glass, expanded mica, expanded perlite, foamed cement and ceramic foams.

The at least one type of particulate inorganic adsorbent and/or absorbent is preferably selected from the group consisting of spheres, hollow spheres, shards, granules, ground lumps, shards and granules, pellets, rings, spheres with core-shell structures, ellipsoids, cubes , cuboids, pyramids, cones, cylinders, rhombuses, dodecahedrons, truncated dodecahedrons, icosahedrons, truncated icosahedrons, dumbbells, tori, platelets, needles with circular, oval, elliptical, square, triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal or star-shaped Cross-sections, in at least one direction of space, curved shards, rings, dumbbells, tori, needles and platelets of particulate, in particular non-combustible, inorganic adsorbents and/or absorbents.

Particulate adsorbents and/or absorbents are preferably selected from the group consisting of activated coke, activated coke/lime hydrate, the phyllosilicates described above, zeolites, silica gels, aluminum oxide, alumina, activated alumina, metal-organic frameworks (MOFs) and trass.

The particulate adsorbents and/or absorbents can be used in a circular container with an air-permeable bottom and air-permeable cover. For this purpose, the circle Round container placed on the circular upper end of the outer tube of the device according to the invention, so that the air flowing out is passed through the bed in the container.

The particulate, inorganic carrier materials, the particulate, inorganic, bactericidal and/or virucidal materials and the particulate adsorbents and/or absorbents preferably have an average particle size, determined by sieve analysis, of 500 μm to 20 mm, in particular 3 mm to 15 mm.

The coatings contain at least one biocide, in particular at least one bactericide and/or virucide, in particular at least one pharmaceutical and/or disinfectant, which is/are fixed to the cured binder matrix of the coating in the form of microparticles and/or dispersed or dissolved in the cured binder matrix is or are.

The biocides are preferably solids or liquids with a boiling point at atmospheric pressure above 150° C. or a decomposition temperature above 150°. Or they have no boiling point and/or a very low vapor pressure at their service temperature like ionic liquids. They do not emit unpleasant odors and harmful, toxic and/or corrosive substances such as chlorine, bromine, iodine, organic halogen compounds, organic and inorganic acids, ammonia, organic amines, inorganic and organic sulfur compounds such as hydrogen sulfide or mercaptans, ozone, organic or inorganic phosphorus compounds such as Phosphines or organic compounds such as formaldehyde, ketones, esters or terpenes at the temperatures at which the coated substrates are used.

The solid biocides, in particular the solid bactericides and/or virucides, are preferably microparticles at their temperature of use, which can be produced, for example, by spray drying (cf. R. Vehring in "Pharmaceutical Particle Engineering via Spray Drying", in Pharmaceutical Research 2007, Expert Review ).

Like the carrier materials, the microparticles and macroparticles can have a wide variety of morphologies such as spheres, hollow spheres, shards, granules, ground lumps, shards and granules, pellets, rings, spheres with core-shell structures, ellipsoids, cubes, cuboids, pyramids, cones, cylinders , rhombuses, dodecahedrons, truncated dodecahedrons, icosahedrons, truncated icosahedrons, dumbbells, tori, platelets, needles with circular, oval, elliptical, square, triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal or star-shaped cross-sections and/or in at least one direction of space curved shards, rings, dumbbells, tori, needles and plates. In addition, the corners and edges can be rounded. Two or more microparticles can form aggregates or agglomerates. The microparticles can be of the same or different types. Two or three cylindrical microparticles may be bonded to each other in a T or Y-shape. Last but not least, their surface can contain depressions, resulting in strawberry-shaped, raspberry-shaped or blackberry-shaped morphologies.

In the context of the present invention, the diameter of microparticles or macroparticles that do not have a spherical shape is considered to be the longest distance laid through the microparticles or macroparticles.

The average diameter or the average particle size of the microparticles and macroparticles is preferably determined by light microscopy, dry sieving, wet sieving, Coulter counter measurements or Fraunhofer scattering or microscopically and visually by counting.

(A detailed description of some of these virucides can be found in A.S. Galabov, "Virucidal agents in the of manorapid synergy™", in GMS Hospital Hygiene Interdisciplinary, 2007 2(1): Doc 18).

Other suitable bactericides and/or virucides are polyoxometalates, which are referred to below with the abbreviation “POM”.

The elemental composition and the structure of the POM can vary widely.

• - the decavanadate anion, V ₁₀ O ₂₈ ⁶ ",
• - the paratungstate anion, H ₂ W ₁₂ O ₄₂ ^10- ,

• - the Weakley-Yamase structure, XM ₁₀ O ₃₆ ^n- , and
• - the Dexter-Silverton structure, XM ₁₂ O ₄₂ ^n- ,

Here, the exponent n is an integer from 3 to 20 denotes the valency of an anion, which varies depending on the X and M variables.

Formulas I to XIII can serve as a further organizing principle for POM:

• - (BW₁₂O₄₀)^5- (I),
• - (W₁₀O₃₂)^4- (II),
• - (P₂W₁₈O₆₂)^6- (III),
• - (PW₁₁O₃₉)^7- (IV),
• - (SiW₁₁O₃₉)^8- (V),
• - (HSiW₉O₃₄)^9- (VI),
• - (HPW₉O₃₄)^8- (VII),
• - (TM)₄(PW₉O₃₄)^t- (VIII),
• - (TM)₄(P₂W₁₅O₅₆)₂ ^t- (IX),
• - (NaP₅W₃₀O₁₁₀)^14- (X),
• - (TM)₃(PW₉O₃₄)₂ ^12- (XI)

und

• (P₂W₁₈O₆)^6- (XII).

• - (BW ₁₂ O ₄₀ ) ^5- (I),
• - (W ₁₀ O ₃₂ ) ^4- (II),
• - (P ₂ W ₁₈ O ₆₂ ) ^6- (III),
• - (PW ₁₁ O ₃₉ ) ^7- (IV),
• - (SiW ₁₁ O ₃₉ ) ^8- (V),

• - (TM) ₃ (PW ₉ O ₃₄ ) ₂ ^12- (XI)

and

• ( ^{P2 W18 O6 )6-} _{( XII )} .

In formulas I to XII, TM represents a divalent or trivalent transition metal ion such as Mn ²⁺ , Fe ²⁺ , Fe ³⁺ , Co ²⁺ , Co ³⁺ , Ni ²⁺ , Cu ²⁺ and Zn ²⁺ . The exponent t is an integer and denotes the valence of an anion, which varies depending on the valence of the variable TM.

• - (A_xGa_yNb_aO_b)^z- (XIII).

POMs of the general formula XIII can also be considered:

• - (A _x Ga _y Nb _a O _b ) ^z- (XIII).

In formula XIII, the variable A is phosphorus, silicon or germanium and the subscript x is 0 or an integer from 1 to 40. The subscript y is an integer from 1 to 10, the subscript a is one is an integer from 1 to 8 and the subscript b is an integer from 15 to 150. The exponent z varies depending on the nature and degree of oxidation of the variable A. Aqua complexes and active fragments of POM XIII can also be considered.

When the index x is 0, y is preferably 6-a, where the index a is an integer from 1 to 5 and the index b is 19.

When the variable A is silicon or germanium, the subscript x is 2, the subscript y is 18, the subscript a is 6, and the subscript b is 77.

If the variable A is P, then the index x is 2 or 4, the index y is 12, 15, 17, or 30, the index a is 1, 3, or 6, and the index b is 62 or 123.

In addition, the isomers of the POM come into consideration. Thus, the Keggin structure has five isomers, the alpha, beta, gamma, delta, and epsilon structure. Furthermore, defect structures or lacunar structures as well as partial structures come into consideration.

The anions I to XIII are preferably used in the form of salts with cations which are approved for cleaning and personal care and pharmaceutical use.

Also contemplated are natural, modified natural, and synthetic cationic oligomers and polymers, i.e., oligomers and polymers bearing primary, secondary, tertiary, and quaternary ammonium groups, primary, secondary, and tertiary sulfonium groups, and/or primary, secondary, and tertiary phosphonium groups. Synthetic oligomers and polymers are common and well known and are used, for example, in electrocoatings. Examples of natural cationic oligomers and polymers are polyaminoaccharides such as polyglucosamines such as chitin, N-acetylglycosides and in particular chitosan.

The chain length and the molecular weight of the chitosan can be varied very widely. Thus, short and long chain length and/or low and high molecular weight chitosans can be used. They can be connected to the POM by chemical crosslinking, entanglement with the polymeric chains and/or by covalent and/or ionic bonds, by hydrogen bonds and/or by Van der Waals forces and/or London forces.

In a particularly preferred embodiment, a POM-chitosan composite is used.

The POM microparticles described above are unmodified, oxygen-substituted, functionalized, aggregated, and/or agglomerated. For example, they can be functionalized and agglomerated. However, they can also be non-functionalized and aggregated.

The POM microparticles to be used according to the invention can be produced with the aid of customary and known wet-chemical processes such as precipitation processes. However, it is also possible to dissolve the POM in water and spray the resulting solution against a stream of warm air. It is also possible to evaporate the solution in vacuo by irradiating it with IR radiation. Furthermore, it is possible to apply solutions, in particular aqueous solutions, of POM to cold surfaces such as deep-frozen, smooth metal surfaces, dry ice, deep-frozen organic solvents and liquefied gases such as methane, ethane, propane, butane, methylcyclohexane or petrol, liquid nitrogen or liquid helium to spray and to vaporize the dry ice or liquid substances.

Other suitable bactericides and/or virucides are ionic liquids. They consist exclusively of ions (cations and anions). They can consist of organic cations and organic or inorganic anions or of inorganic cations and organic anions.

In principle, ionic liquids are molten salts with a low melting point. Not only those salt compounds which are liquid at ambient temperature are included, but also all salt compounds which preferably melt below 150.degree. C., preferably below 130.degree. C. and in particular below 100.degree. In contrast to conventional inorganic salts such as table salt (melting point 808°C), lattice energy and symmetry are reduced in ionic liquids due to charge delocalization, which can lead to freezing points down to -80°C and below. Due to the numerous possible combinations of anions and cations, ionic liquids with very different properties can be produced (see also Römpp Online 2007, »ionic liquids«).

Suitable organic cations are all cations that are customarily used in ionic liquids. The onium compounds are preferably non-cyclic or heterocyclic.

Preferred are non-cyclic and heterocyclic onium compounds from the group consisting of quaternary ammonium, oxonium, sulfonium and phosphonium cations and uronium, thiouronium and guanidinium cations in which the single positive charge is delocalized over several heteroatoms, used.

Particular preference is given to using quaternary ammonium cations and very particular preference to using heterocyclic quaternary ammonium cations.

In particular, the heterocyclic quaternary ammonium cations are selected from the group consisting of pyrrolium, imidazolium, 1H-pyrazolium, 3H-pyrazolium, 4H-pyrazolium, 1-pyrazolinium, 2-pyrazolinium, 3-pyrazolinium, 2,3-dihydro-imidazolinium, 4,5-dihydro-imidazolinium, 2,5-dihydro-imidazolinium, pyrrolidinium, 1,2,4-triazolium (quaternary nitrogen atom in 1-position), 1,2 ,4-Triazolium (4-position quaternary nitrogen), 1,2,3-Triazolium (1-position quaternary nitrogen), 1,2,3-Triazolium (4-position quaternary nitrogen), oxazolium- , isooxazolium, thiazolium, isothiazolium, pyridinium, pyridazinium, pyrimidinium, piperidinium, morpholinium, pyrazinium, indolium, quinolinium, isoquinolinium, quinoxalinium and indolinium cations.

The POM anions listed above are particularly preferably used.

In the same way, all anions that do not form crystalline salts with the organic or inorganic cations of the ionic liquids can be considered as organic anions, whose melting point is above 150°C and which also do not enter into any undesirable interactions with the organic or inorganic cations, such as chemical reactions.

The organic anions of aliphatic, cycloaliphatic and aromatic acids are preferably derived from the group consisting of carboxylic acids, sulfonic acids, acidic sulfate esters, phosphonic acids, phosphinic acids, acidic phosphate esters, hypodiphosphinic acids, hypodiphosphonic acids, hypodiphosphonic acids, acidic boric acid esters, boric acids, acidic silicic acid esters and acidic silanes, or they are selected from the group consisting of aliphatic, cycloaliphatic and aromatic thiolate, alcoholate, phenolate, methide, bis(carbonyl)imide, bis(sulfonyl)imide and carbonylsulfonylimide anions.

known. Acetate anions are very particularly preferably used.

In particular, 1-ethyl-3-methylimidazolium acetate (EMIM Ac) and tetra-(1-ethyl-3-methylimidazolium)tungstate silicate are used as the ionic liquid.

Materials that are only poorly soluble in water are preferably used as particulate, inorganic, bactericidal and/or biocidal materials, so that the materials are not attacked by aerosols. In addition, they should not be highly toxic or carcinogenic to humans or animals and should be safe to handle and dispose of.

Examples of suitable particulate, inorganic, bactericidal and/or biocidal materials are boric acid, boron oxide, disodium octaborate tetrahydrate, disodium tetraborate pentahydrate, disodium tetraborate decahydrate, copper hydroxide, basic copper carbonate, granulated copper, copper flakes, dicopper oxide, copper oxide, copper thiocyanate, silver, silver chloride, silver bromide, calcium carbonate, hydrated lime, lime , calcium magnesium oxide tetrahydrate, calcium magnesium oxide and/or titanium dioxide.

The bactericidal and/or virucidal coatings on the carrier materials described above, containing the biocides described above, are preferably produced from liquid or pulverulent coating materials. Water-based coating materials or those based on organic solvents are used. The liquid coating materials can contain dissolved substances in molecularly disperse form, or they can preferably be dispersions.

The powdered coating materials are applied with the help of customary and known processes such as electrostatic spraying, fluidized bed coating and coil coating processes and subsequent melting. It is advantageous if the substrates are thermally stable, so that they are not damaged by heating. It is a further advantage of powder coating that the solid biocides and/or virucides described above can be sprayed simultaneously with the powders. As a result, the microparticles are concentrated at the surface of the powder coating, where they firmly adhere to the curing coating, making them available for the elimination of bacteria, viruses and virions.

The liquid coating compositions or coating materials can be applied using customary and known coating methods such as dipping methods, spraying methods, in particular compressed air spraying, airless spraying, air-mix spraying, brushing, hot spraying, curtain pouring, knife coating, two-component coating, electrostatic spraying, electrostatically assisted spraying, roller application, wiping, pouring , troweling, strip coating, centrifugation and drum coating.

The solid biocides described above can be dispersed as solid microparticles in the liquid coating materials. However, it is advantageous if some or all of the microparticles are applied to the coated substrate before the liquid coating materials harden. This creates easily accessible virucidal and/or bactericidal centers which can also serve as spacers and thus prevent the coated carrier materials from sticking together.

In the case of thermoplastic powder coating materials, the applied coating materials are physically cured. That is, they solidify on cooling.

Depending on which reactive functional groups are present in the coating materials, the latter are cured thermally or by free-radical polymerization, which is set in motion by actinic radiation or by free-radical initiators. However, both mechanisms can also be combined in one coating material. One speaks then of "Dual Cure".

In the context of the present invention, actinic radiation is understood as meaning corpuscular radiation such as electron radiation, alpha radiation, beta radiation and neutron radiation, and electromagnetic radiation such as infrared radiation, visible light, UV radiation, X-rays and gamma radiation. In particular, visible light and UV radiation are used.

Table 3 gives an overview of suitable functional groups for the crosslinking reactions.

In a preferred method for coating the above-described, particulate, inorganic, inert carrier materials, a system is used which includes automatic feeding of the particulate carrier materials onto an endless belt with a vibrating section, which is guided over at least two transport rollers. The supplied particulate carrier materials are vibrated and sprayed in a first station with at least one of the liquid coating materials described below. The shaking ensures that the substrates are coated as evenly as possible. Before the coating materials are cured, they are sprayed with microparticles of at least one type of biocide while being shaken in a second station, so that the microparticles are evenly distributed on and in the coating materials and remain sticky. In a third station, the coating materials are cured - also with shaking - thermally in a continuous oven, with IR radiators and/or with UV radiation, so that the biocidal coating forms on the carrier materials. The shaking prevents the particles from sticking together and the hardened coating materials from forming any firmly adhering films on the endless belt. If this does happen to a certain extent, the particles are separated in a third station and then discharged into a storage vessel. The one on that Residues of hardened coating materials adhering to the endless belt are scraped off with squeegees after the endless belt has been deflected.

The coating compositions or coating materials can be divided into groups on the basis of their binders.

Coating materials based on oils

These coatings contain natural, drying oils that undergo auto-oxidative polymerization in the presence of catalysts and atmospheric oxygen. Chemically modified oxidative drying oils such as polyurethane oils or low molecular weight polybutadiene oils can also be used.

Coating materials based on cellulose

Nitrocellulose paints usually contain additional resins and solvents to improve their performance properties. Other coating materials based on cellulose contain organic cellulose esters such as cellulose acetate, cellulose acetate butyrate or cellulose acetate propionate.

Rubber-based coating materials

These coating materials based on chlorinated rubber, chlorinated rubber-alkyd resin combinations and chlorinated rubber-acrylic resin combinations are resistant to water, which can be of advantage for the present invention in special applications.

Coating materials based on vinyl resins

These coating materials contain polyolefins and polyolefin derivatives such as polyethylene and polyisobutene. Ethylene copolymers such as ethylene vinyl acetate copolymers or ethylene maleic anhydride copolymers are water soluble and can form salts. Chlorosulfonated polyethylenes have a very high chemical resistance, especially against oxidizing agents.

Coating materials based on polyvinyl halides and vinyl halide copolymers

Coating materials containing polyvinyl chloride and chlorinated polyvinyl chloride have advantageous mechanical properties and high abrasion resistance. Coating materials with vinylidene chloride copolymers have numerous technical applications. Important examples of copolymers without additional functional groups are vinyl acetate, dibutyl maleate or isobutyl vinyl ether copolymers. Terpolymers with carboxyl groups are made with dibutyl maleate or vinyl acetate and a dicarboxylic acid. Copolymers and terpolymers with hydroxyl groups are obtained with hydroxyacrylates or with vinyl acetate and vinyl alcohol. Vinylidene chloride copolymers with acrylonitrile or acrylic resins have excellent chemical resistance and are primarily used as films for food packaging. Polyvinylidene difluoride is a thermoplastic fluoropolymer and can therefore be used for powder coatings. Further examples of fluoropolymers for coating materials are cyclic perfluorinated polymers. Crosslinkable perfluorinated polymers contain epoxy groups, ether groups, hydroxyl groups or carboxyl groups as crosslinking functional groups.

Coating materials based on vinyl ester polymers and copolymers

Coating materials based on vinyl acetate polymers and vinyl acetate copolymers with vinyl laurate, dibutyl maleate or crotonic acid have particularly high lightfastness and strong adhesion to metals. Polyvinyl alcohol is commonly produced by the hydrolysis of polyvinyl acetate. It has a high water solubility and is resistant to oils and fats, lubricants and waxes. Polyvinyl acetals such as polyvinyl formal and polyvinyl butyral are made by reacting polyvinyl acetate with aldehydes. They can be viewed as terpolymers of vinyl acetate, vinyl alcohol and vinyl acetal. They are physically crosslinkable, but can also be chemically crosslinked through hydroxyl groups.

Coating materials based on vinyl ether polymers

Vinyl ether polymers are made from methyl vinyl ether or isobutyl vinyl ether and are often used as plasticizing resins in coatings.

polystyrene and styrene copolymers

Because of their high glass transition temperature, polystyrene dispersions do not form films at room temperature. However, the hardness of polystyrene can be adapted to the specific application of the coating material over a wide temperature range by copolymerization with soft monomers such as butadiene and acrylate ester.

Coating materials based on acrylates

Polyacrylates are only slightly attacked by chemicals and therefore give the coating materials a high level of resistance. They are colourless, transparent and do not yellow even after prolonged thermal stress. They do not absorb radiation above 300 nm and are therefore not degraded by UV radiation as long as they do not contain styrene or similar aromatic compounds. They have no unstable double bonds, but have a high, lasting gloss and are hydrolytically stable. Depending on their lateral functional groups, they can be crosslinked in a variety of ways (see Table 3).

alkyd coating materials

Alkyd resin binders contain oils/fatty acids, dicarboxylic acids (mainly phthalic acid or phthalic anhydride) and polyalcohols. They are classified as short oil, medium oil or long oil resins. They are modified with natural fatty acids or oils. For special technical applications, the alkyd resins are additionally modified with resin acids, benzoic acid, styrene, vinyl toluene, isocyanates, acrylates, epoxides and silicone compounds.

Coating materials based on saturated polyesters

Saturated polyesters are made by the polycondensation of polycarboxylic acids such as terephthalic acid and polyalcohols such as ethylene glycol. Polyesters containing hydroxyl groups can be crosslinked with melamine resins, benzoguanamine resins and blocked isocyanates. Saturated polyesters containing carboxyl groups can be crosslinked with triglycidyl isocyanurate or epoxy resins. Saturated polyesters containing lateral acrylate groups can be cured by UV radiation and electron beams.

Coating materials based on unsaturated polyesters

Unsaturated polyester resins or UP resins are soluble linear polycondensation products made by the reaction of commonly unsaturated polybasic carboxylic acids such as maleic acid or fumaric acid and dihydric alcohols such as ethylene glycol. Curing is initiated by peroxide or C-C radical initiators. However, they can also be cured by UV radiation in the presence of photoinitiators.

Coating materials based on polyurethanes

Polyurethanes are binders with urethane, urea, biuret, or allophanate groups as linking groups. The coating materials contain low-molecular, oligomeric or polymeric components that can be crosslinked with blocked polyisocyanates in one-component systems and with free polyisocyanates in two-component systems. The cured coatings have high chemical resistance and excellent light and weather stability.

Coating materials based on epoxy resins

There are different types of epoxy resins such as bisphenol A resins, bisphenol F resins, epoxy novolacs, aliphatic epoxy resins, cycloaliphatic epoxy resins, glycidyl esters and heterocyclic epoxy compounds. You can ver by amines, polyesters, phenolic resins, amino resins or polyisocyanates become wet. In addition, they can be chemically modified so that epoxy resin esters and epoxy resin (meth)acrylic acid esters result.

Coating materials based on urea, benzoguanamine and melamine resins

Alkylated urea, benzoguanamine, glycoluril, toluenesulfonamide and melamine formaldehyde resins are a versatile group of crosslinking agents for hydroxyl, amide, carboxyl containing polymers. They are used in both waterborne and solventborne coatings.

Coating materials based on phenolic resins

Phenolic resins are polycondensation products of phenols and formaldehyde and are self-crosslinking in the presence of bases or basic salts. Phenolic resins are pale yellow to dark brown in color and are therefore not suitable for color applications. Because they form hard and brittle films, they must be mixed with other resins such as epoxy resins, polyvinyl butyral resins, or polyester resins.

Coating materials based on silicone resins and organic-inorganic hybrid resins

Polysiloxane or silicone resins for coating purposes are prepared from mixtures of di- or trifunctional organosilane monomers such as phenyl- and methyltriethoxysilane, methylphenyldichlorosilane and dimethyldichlorosilane by controlled hydrolysis and condensation. However, pure silicone resins are often too soft and too thermoplastic for coating purposes. Therefore, they are mixed with common and well-known resins such as alkyd resins, acrylic resins, epoxy resins and phenolic resins.

A particularly well suited group of silicone resins are hybrids of siloxane-polyurethane and siloxane-epoxy or siloxane-acrylate and sol-gel polymers.

The sol-gel hybrid polymers are prepared by the polycondensation of siloxanes containing hydrolyzable groups and the organic moieties described below.

The essential component of the hybrid dispersions are surface-modified, cationically stabilized, inorganic nanoparticles of at least one type, in particular one type.

The nanoparticles to be modified are preferably selected from the group consisting of main and subgroup metals and their compounds. The main and subgroup metals are preferably selected from metals of the third to fifth main group, the third to sixth and the first and second subgroup of the periodic table of the elements, and the lanthanides. Particularly preferred are boron, aluminum, gallium, silicon, germanium, tin, arsenic, antimony, silver, zinc, titanium, zirconium, hafnium, vanadium, niobium, tantalum, molybdenum, tungsten and cerium, especially aluminum, silicon, silver, cerium, Titanium and zirconium used.

The nanoparticles to be modified preferably have a primary particle size <50 nm, preferably 5 nm to 50 nm, in particular 10 nm to 30 nm.

The nanoparticles or their surface are with at least one compound of the general formula XIV: [(S-) _o -L-] _m M(R) _n (H) _p modified. (XIV)

The modification can be carried out by physical adsorption of the compounds XIV on the surface of the unmodified nanoparticles and/or by chemical reaction of the compounds XIV with suitable reactive functional groups on the surface of the unmodified nanoparticles. The modification preferably takes place via chemical reactions.

Examples of suitable metals M are those described above.

Preferably, the reactive functional group S is selected from the group consisting of (S 1) reactive functional groups containing at least one bond which can be activated with actinic radiation, and (S 2) reactive functional groups which are linked to groups of their own kind (“with themselves “) and/or undergo thermally initiated reactions with complementary reactive functional groups. Examples of suitable reactive functional groups (S 2) are the groups described above, in particular epoxide groups.

In the context of the present invention, a bond which can be activated with actinic radiation is understood as meaning a bond which becomes reactive when irradiated with actinic radiation and undergoes polymerization reactions and/or crosslinking reactions with other activated bonds of its type, which proceed according to free-radical and/or ionic mechanisms. Examples of suitable bonds are carbon-hydrogen single bonds or carbon-carbon, carbon-oxygen, carbon-nitrogen, carbon-phosphorus or carbon-silicon single bonds or double bonds. Of these, the carbon-carbon double bonds are particularly advantageous and are therefore used with very particular preference according to the invention. For the sake of brevity, they are hereinafter referred to as “double bonds”.

Accordingly, the reactive group (S1) preferred according to the invention contains one double bond or two, three or four double bonds. If more than one double bond is used, the double bonds can be conjugated. According to the invention, however, it is advantageous if the double bonds are isolated, in particular each terminally, in the group (S1) in question here. According to the invention, it is of particular advantage to use two double bonds, in particular one double bond.

The bonds that can be activated with actinic radiation can be via carbon-carbon bonds or ether, thioether, carboxylic acid ester, thiocarboxylic acid ester, carbonate, thiocarbonate, phosphoric acid ester, thiophosphoric acid ester, phosphonic acid ester, thiophosphonic acid ester, phosphite, thiophosphite, sulfonic acid ester , amide, amine, thioamide, phosphoric acid amide, thiophosphoric acid amide, phosphonic acid amide, thiophosphonic acid amide, sulfonic acid amide, imide, urethane, hydrazide, urea, thiourea, carbonyl, thiocarbonyl, sulfone or sulfoxide groups , but in particular via carbon-carbon bonds, carboxylic acid ester groups and ether groups, be connected to the linking group L.

The variable H represents a hydrolyzable monovalent group or a hydrolyzable atom.

Examples of suitable hydrolyzable atoms are hydrogen and halogen, especially chlorine and bromine.

Preferably the hydrolyzable monovalent groups are used. Examples of suitable groups of this type are groups of the general formula XV: -XR (XV).

In the general formula XV, the variable X represents an oxygen atom, a sulfur atom and/or a group >NR ² , in which R ² represents an alkyl group having 1 to 4 carbon atoms, in particular methyl, ethyl, propyl and n-butyl. Preferably X is an oxygen atom.

R represents a monovalent organic radical. The monovalent radical R can be substituted or unsubstituted; preferably it is unsubstituted. It can be aromatic, aliphatic or cycloaliphatic. A monovalent radical R is considered to be aromatic if X is linked directly to the aromatic radical. This rule applies analogously to aliphatic and cycloaliphatic radicals. Linear or branched, in particular linear, aliphatic radicals are preferably used. Lower aliphatic radicals are preferred. Of these, the methyl group or the ethyl group is most preferably used.

The variable L represents an at least divalent, especially divalent, organic linking group.

Examples of suitable complexing agents are unsaturated carboxylic acids and beta-dicarbonyl group compounds such as methacrylic acid, acetylacetone and ethyl acetate.

From a methodological point of view, the modification of the surface of the nanoparticles does not offer any special features, but is carried out according to the usual and known methods, which can be found, for example, in the international patent application WO 99/52964 A2 Page 10, line 22 to page 11, line 17, and Examples 1 to 20, page 14, line 10 to page 20, line 24, or from the German patent application DE 197 26 829 A 1, examples 1 to 6, column 5, line 63, to column 8, line 38 are known. Preference is given to using the proportions of compounds XIV to unmodified nanoparticles specified there.

The content of the surface-modified, inorganic nanoparticles in the dispersions can vary widely and depends on the requirements of the individual case. The nanoparticles are preferably present in the dispersions in an amount of 60 to 98% by weight, based on the total amount of the components.

In addition to the resins or binders described above, the coating materials may contain customary and known additives. Preferably, these are reactive diluents that can be cured thermally or by actinic radiation, in particular by UV radiation, low-boiling organic solvents and high-boiling organic solvents, water, UV absorbers, free-radical scavengers, thermolabile free-radical initiators, photoinitiators, catalysts for the thermal crosslinking, deaerating agents, slip additives, polymerization inhibitors, defoamers, wetting agents, dispersants, adhesion promoters, smoothing agents, film-forming aids, anti-sag agents, rheology aids (thickeners), flame retardants, drying agents, anti-skinning agents, corrosion inhibitors, waxes and matting agents.

In a further advantageous embodiment, the bactericidal and/or virucidal coatings are applied to the above-described particulate, inorganic, inert carrier materials by spraying on biocidal metals such as copper or silver using electric twin-wire arc spraying. This has the significant advantage that this technology is a mature process and that considerable amounts of expensive biocidal copper can be saved as a result, which also reduces the weight of the device according to the invention.

Devices 1 according to the invention with arrangements of pairs 6 of counter-rotating impellers 6L; 6R

The mobile tubular device 1 according to the invention was 100 cm high from its base 1.9 to its upper end 1.6. It had a tubular, vertical wall 1.1 with a circular circumference, an outer diameter of 20 cm and an inner space 1.5. Its wall thickness was 1 cm. Your floor area 1.8 with the standing floor 1.9 was 10 cm high. It was made of polymethyl methacrylate PMMA with a density of 1.18 g/cm. In your floor area 1.8 there was a receptacle 9.1 with ice slide rails 9.2, into which a rechargeable accumulator 9 and an electronic control unit 8 connected to it were inserted. The electronic control unit 8 evaluated the signals from the miniature anemometer (not shown) in the upper horizontal opening 1.7 of the vertical wall 1.1 and adjusted them due to the obtained readings the speed and power output of the counter-axial rotating fan 2.

The counter-axially rotating fan 2, which was operated with a voltage of 12 V DC and was anchored to the vertical wall 1.1 with the rotating bracket 2.4, had a horizontal width of 6 cm, a horizontal length of 6 cm and a vertical height of 7 cm up. The clockwise fan 2.1 was mounted on the suction side 2.6, and the counterclockwise fan 2.2 was on the outlet side 2.7. The contaminated air, which was sucked through eight intake pipes 3 with a circular cross-section, a 1.5 mm thick wall made of PMMA, a clear width of 25.5 cm and protective grilles 3.5 into the intake chamber 2.3 with a height of 4 cm, was discharged through the 3 cm high air deflection cone 2.8 made of PMMA and directed to the intake side 2.6 by the circumferential, outwardly inclined air deflector plate 2.5.

In the center of the upper opening 1.7 of the tubular vertical wall 1.1 was the upper bearing 6.9 made of polyetherketone PEK for the fixed, continuous, tubular, central pivot axis 6.1 made of PEK. The upper bearing 6.9 was attached to the inner wall 1.2 by four symmetrically arranged, horizontal, lateral anchors 6.10 made of stainless steel.

On the inside 1.2 of the wall 1.1, a 100 μm thick biocidal coating 5 of the type described below was applied over a vertical length of about 80 cm. The biocidal coating 5 had an ISO microroughness of N12. Biocidal coatings 5 of the type mentioned were also on the horizontal floor 2.9 of the intake chamber 2.3, the surface of the air guide cone 2.8, the horizontal lateral anchorage of the lower bearing 6.3, the horizontal lateral anchorage 6.8.1 of the bearing 6.8 and the counter-rotating impellers 6R; 6L

The fixed, continuous, 76 cm long axis of rotation 6.1 ran after the assembly of the vertical arrangement of pairs (6) arranged one above the other, each with two counter-rotating impellers 6L; 6R along the longitudinal axis A of the tubular interior 1.5 to the lower bearing 6.2 made of PEK and the anchor 6.3 was made of stainless steel. The middle bearing 6.8 with a height of 1 cm and the four lateral anchorages 6.8.1 as a stabilization for the fixed, continuous axis of rotation 6.1 was of the same design.

The tubular axis of rotation 6.1 had a circular outline, a diameter of 1.5 cm and an internal width of 0.7 cm. For assembly, it was fixed centrally in the lower bearing with a screw thread 6.1.4 with a length of 1.5 cm (step 1). A 3 mm thick, elastic damping ring 6.12 was placed on the horizontal surface of the lower bearing 6.2 (step 2). The first centrosymmetric component 6.13, enclosing the axis of rotation 6.1, was then fitted with a lower horizontal standing plate and a vertical sleeve which, at a distance 6.4.2a of 3 cm, was fitted into the disc-shaped, horizontal running surface 6.4.7 with a diameter from edge to edge of 4. 5 cm, was placed and - like other components with the same function - was attached to the surface of the rotary axis 6.1 with fixing screws 6.4.8 (step 3).

Component 6.13 consisted of polished, high-alloy steel and had a wall thickness of 0.3 cm at all positions. The same applied to the second and third component 6.14; 6.15 and for the other structurally identical components.

On the first horizontal running surface 6.4.7 of component 6.13, the first left-hand impeller 6L with its rotatable impeller hub 6.4; 6.4.1a; 6.4.1b; 6.1.1 at a height of 1cm (step 4). The impeller 6L had four impeller blades 6L.2 arranged radially, slightly curved horizontally counter to the direction of rotation, 0.3 cm thick, about 1 cm wide and ending in a curve with an inclination suitable for the left rotation 6.6L (in the 2 shown schematically as squares). The blades 6L2 were connected directly to the impeller hub 6.4 (connection 6L1). When rotating, the impeller 6L described a circle with a diameter of 13.3 cm, so that the impeller blades were at a minimum distance from the surface of the biocidal coating 5 of about 0.15 cm.

The impeller 6L was made of polyoxymethylene POM-C with a thermal conductivity λ of 0.25 W/(m.K) by injection molding. The impeller hub 6.4 and the running surfaces 6.4.7 made of steel had a coefficient of sliding friction µSliding against hardened and ground steel at 23 °C and 50% humidity, a contact pressure of P = 0.05 MPa (0.5 bar), a speed with dry lubrication of v = 0.6 m/s (21.6 km/h) and a temperature near the tread of t = 60 °C of 0.1.

These parameters applied in the same way to all impellers 6; 6L; 6R.

After placing the first impeller 6L, component 6.14 was attached (step 5) and then the first clockwise rotating impeller 6R was placed (step 6). The component 6.14 had a height of 6 cm. Together with the component 6.13, the total height along the axis of rotation 6.1 was 10 cm.

In an analogous manner, the components were 6.15 and 6.16 for the second impeller pair 6; 6L; 6 was attached in steps 7-8 and 9-10, resulting in a total height of 8 cm along the axis of rotation 6.1. Thus, 6.8 remained below the middle bearing. still room for a third pair of impellers 6; 6L; 6R (steps 11 and following).

After attaching the middle bearing 6.8. were in an analogous manner, three more pairs of impellers 6; 6L; 6R so that the arrangement had a total of six such pairs. The entire surfaces of the wing blades 6L.2; 6R.2 were coated with the biocidal coatings 5 described below in the various embodiments.

In a second embodiment of the impellers 6; 6L; 6R these were in the form of a wheel with six spokes radiating radially from the impeller hub 6.4 to the orbiting ring of the wheel. The outer edge of the circumferential ring was about 0.13 cm from the biocidal coating 5. The spokes were shaped like strips and had the for the left or right direction of rotation 6.6L; 6.6R appropriate incline. In order to enlarge the surfaces, these could have elevations and depressions such as wave crests and wave troughs (not shown). This type of impellers 6; 6L; 6R were coated with the biocidal coatings 5 described below.

When the mobile devices 1 according to the invention were put into operation in both embodiments, the impellers 6; 6L; 6R rotated in opposite directions, as a result of which strong air vortices 6.7 were generated, which caused intensive contact of the decontaminated air with the biocidal coatings 5.

In order to create an additional suction effect, a plastic attachment 10 in the form of an inverted funnel with a funnel tube 10.1, a funnel stem 10.2 with an upper edge 10.7 and a funnel truncated cone 10.3 with a funnel inside 10.4 could be fitted into the surrounding upper end by means of vertical plug connections 10.6 1.6 of the tubular vertical wall 1.1 are attached. Air inlets 10.8 were arranged between the connectors 10.6. In a further embodiment of the attachment 10, the inverted funnel has been inserted into the upper end 1.6 by means of a socket ring 10.6 (not shown). This eliminated the air intakes 10.8.

In yet another embodiment, a circular, can-shaped attachment with an air-permeable base and an air-permeable lid was inserted into the upper end 1.6 with the aid of a plug-in ring 10.6 (not shown). The attachment was filled with a bed of bentonite with an average particle size of 7 mm determined by sieve analysis (not shown). Any decomposition products that may have escaped as a result of the elimination were adsorbed and/or absorbed or intercalated on the bed.

The construction of a vertical arrangement of pairs 6 of two counter-rotating impellers 6; 6L; 6R with a compound axis of rotation 6.1

For the pairs 6 of counter-rotating impellers 6L; 6R became the impellers 6L described above; 6R used. The impeller hubs 6.4; 6.4.1a; 6.4.1b and treads 6.4.7 had the same dimensions as described above. The lower bearing 6.2 was a first component with a circular circumference, which was arranged symmetrically around the imaginary axis of rotation 6.1 and—like the other components 6.5 for constructing the composite axis of rotation 6.1—was made of stainless steel. It had a socket 6.4.5 for receiving a plug 6.4.6 of the next higher complementary second component 6.5. The sockets 6.4.5 were formed by circumferential, vertical, circular webs 6.4.4, which also function as spacers 6.4.3 for setting the distances 6.4.2a; 6.4.2b; 6.4.2c etc. between the third, fourth etc. components 6.5 were used. An elastic damping ring 6.12 was located between the lower bearing 6.2 and the next higher, complementary second component 6.5. In a distance 6.4.2.a between the bearing 6.2 and the horizontal running surface 6.4.7 of the first next higher component 6.5 were the first Impeller 6R with the impeller hub 6.4 with their treads 6.4.1a; 6.4.1b arranged. In the same way, it was the second impeller 6L with the impeller hub 6.4 and its running surfaces 6.4.1a; 6.4.1b arranged. Together they formed the first pair 6 of counter-rotating impellers 6R; 6L Thus, two components 6.5 plugged one on top of the other always formed a holder for a rotatable impeller hub 6.4.

According to this design principle, vertical arrangements with the desired number of horizontal pairs 6, each consisting of two counter-rotating impellers 6.6; 6.6L; 6.6R with biocidal coatings 5, which were mounted at a fixed distance above one another so as to be rotatable about a composite axis of rotation 6.1, can be produced from standardized components in a simple and advantageous manner.

The construction of 5 also used the possibility of dry lubrication between stainless steel and polyoxymethylene POM-C. The composite axis of rotation 6.1 was composed of stainless steel pins 6.1.3 as sections. The steel pins 6.1.3 had rounded ends, so that they formed sliding surfaces 6.1.2 "fan wheel hub 6.4//section 6.1.3" in the wheel hubs 6.4. The end of the first steel pin 6.1.3 was fixed in the lower bearing 6.2 with an adhesive 6.2.1. The composite axis of rotation 6.1 could be stabilized if required by bearings 6.11 with lateral, horizontal, flexible anchors 6.11.1 for vibration damping.

According to this design principle, vertical arrangements with the desired number of horizontal pairs 6, each consisting of two counter-rotating impellers 6.6; 6.6L; 6.6R with biocidal coatings 5, which were mounted at a fixed distance above one another so as to be rotatable about a composite axis of rotation 6.1, can be produced from standardized components in a simple and advantageous manner.

The production of the biocidal coatings 5

The biocidal coatings 5 produced were on the inside 1.2 of the wall 1.1, which enclosed the interior space 1.5, on the free surfaces of the components 6.5 and, in particular, on the wing blades 6L; 6R. The adhesion of the biocidal coatings 5 on the plastic surfaces of the blades 6L; 6R could be significantly improved by a pre-treatment by plasma etching.

In a first embodiment, the biocidal coating 5a) consisted essentially of a layer produced from at least one coating agent and having a microroughness N8, in which the biocides 5.1 were distributed in a molecularly dispersed or homogeneously dispersed manner.

In a second embodiment, the biocidal coating 5b) essentially consisted of at least one biocidal metal 5.1 such as copper or silver, which was sprayed on using electric twin-wire arc spraying (TWAS). This formed homogeneous layers 5.4, island-like layers 5.4 and/or punctiform elevations 5.4 of metal. Here, too, an uneven microscale coating was advantageous for the biocidal effect.

In a third embodiment, the biocidal coating 5c) consisted essentially of a coating cured thermally and/or with UV radiation h.v, to the surface of which biocidal microparticles 5.3 adhered. This was achieved in that biocidal microparticles 5.3 were sprayed onto the coating materials 5a that had not yet cured, after which the coating materials or coating materials were cured.

The resulting mixture was homogenized and applied by spraying to the above-mentioned free surfaces inside the mobile devices 1 according to the invention and then thermally cured with infrared radiation.

The production of a biocidal coating 5b)

The impeller hubs 6.4 of the impellers 6L; 6R has been covered, and the surfaces of the impeller blades 6L.2; 6R.2 were roughened by plasma etching. They were then coated with a 10 µm thin coating of copper using Twin-wire Arc Spraying (TWAS).

The production of a biocidal coating 5c)

No biocides were initially added to the automotive series clearcoat described above. He was on the roughened by plasma etching surfaces of other blades 6L.2; 6R.2 applied, so that after curing a coating 5a with a layer thickness of 30 μm resulted. The applied coating material 5a was crosslinked to such an extent that its surface still remained very tacky. A mixture of microparticles with an average particle size of 5 μm was then sprayed on as solid biocides 5.3. As the microparticles, copper oxide microparticles, calcium magnesium oxide oxide microparticles, CU ₂ {H ₄ [Si(W ₃ O ₁₀ ) ₄ ]} ▪ xH ₂ O microparticles, microparticles of fludioxonil: 4-(2,2-difluorobenzo [1,3]dioxol-4-yl)pyrrole-3-carbonitrile (IUPAC) and microparticles of octenidine: N,N'-(decane-1,10-diyldi-1(4H)-pyridyl-4-ylidene)bis (octylammonium) dichloride in the weight ratio of 1:2:2:1:1:1.5.

The coating system used was protected against electrostatic charges and had an extraction system. The uncoated, particulate, inorganic, inert carrier materials were metered using an automatic feed device onto a smooth endless belt coated with a non-stick layer and having a total length of 42 m and a horizontal vibrating section of 20 m length and guided over at least two transport rollers. The vibrating section had side walls to prevent the uncoated carrier material from falling down. The uncoated carrier materials fed in were vibrated and sprayed with the liquid coating material in a first station over a length of 8 m at 30 °C, so that a thin, non-cured liquid layer was deposited on the Carrier material formed, which gradually became sticky through evaporation. The shaking ensured that the carrier materials were coated as evenly as possible and did not stick together. Before the coating material was cured, it was sprayed with microparticles of at least one type of biocide and/or virucide while being shaken in a second station with a length of 5 m, so that the microparticles were evenly distributed on and in the coating material and stuck. In a third station, the now biocidal and/or virucidal coating material was thermally cured - also with shaking - in a 5 m long continuous oven at 110 °C, so that the biocidal and/or virucidal coating formed on the carrier material. The shaking prevented the particles from sticking together and/or sticking to the endless belt.

The tests of the effectiveness of the mobile devices according to the invention 1

The effectiveness of the various embodiments of the devices 1 according to the invention was determined using the test device according to FIG 18 tested. For this purpose, a device 1 according to the invention was placed in a correspondingly dimensioned, closed chamber 12 . The outlet opening of the device 1 according to the invention was connected to an exhaust hood 14 with an air discharge line 14.1, through which the exhaust air 3.6 could be discharged. The transition from the device 1 according to the invention to the exhaust hood 14 was sealed at the upper end 1.5 with a peripheral seal 12.1. A solid cell-biological nutrient medium 13 on a previously sterilized film was placed on an air-permeable support 13.1 in the extraction hood 14 via a lock 13.2. In the air discharge line 14.1 were a sensor 15.1 for particle counting by laser diffraction, which was connected to a signal line 15.1.2 with a particle measuring device 15.1.1, and a sensor 15.2 for flow measurement, which was connected to a signal line 15.2.2 with a flow measuring device 15.2. 1 was connected arranged. Another sensor 15.1 for particle counting was placed in the area of the air inlets 3.1 of the device according to the invention and connected to another particle measuring device 15.1.1 via a signal line 15.1.2. The two measuring devices 15.1.1 and the measuring device 15.2.1 sent the measurement signals to the central data processing system 15, where they were evaluated and displayed on the display device 16.

Before determining the performance, the respective chamber 12 and the respective device 1 according to the invention were flushed with high-purity zero-point air (analytical air) at 23° C. and 1.2 bar via the connection 17, the automatically controlled shut-off valve 17.1 and the air inlet nozzle 17.2. As soon as no more particle signals appeared on the display device 16, the rinsing was ended by closing the shut-off valve 17.1, and aerosol clouds 12.6, which for safety reasons contained harmless intestinal bacteria such as Firmicutes, Bacteroidetes, Proteobacteria and Actinobateria, were released via the aerosol feed line 12.3, the blower 12.4, the open shut-off valve 12.5 and the atomizing nozzle 12.2 located inside the chamber 12 are blown into the chamber 12 at 23° C. and 1.2 bar, passed through the respective device 1 according to the invention and discharged via the extractor hood 14 and the air discharge line 14.1.

In the exhaust hood 14, the exhaust air 3.6 was blown directly onto the solid cell-biological nutrient medium 13 on the previously sterilized film.

After exposure for 15 minutes, 30 minutes, 45 minutes, 60 minutes, the cell-biological nutrient medium 13 was removed from the removal lock 13.2 on the previously sterilized film, and a new nutrient medium 13 was introduced immediately. After that, it was tested in a customary and known manner whether there were still intestinal bacteria on the nutrient medium 13 that were capable of reproduction. It was found that after just 15 minutes of exposure there were no viable intestinal bacteria present. This was in accordance with the particle measurement with the sensor 15.1 and the measuring device 15.1.1 in the exhaust air 3.6, with which no more particles of the size in question could be detected.

Another significant advantage of the devices according to the invention

The use of counter-rotating fans proved to be a particular advantage because this type of fan has a particularly high flow rate and efficiency. This made it possible to operate the fans at comparatively low speeds, which significantly reduced the noise level.
