Description

field of invention

The present invention relates to a mobile device for cleaning and disinfecting room air that can be operated by a temperature difference.

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

Furthermore, the present invention relates to the use of the mobile device, which can be operated by a temperature difference, 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.

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.

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 incorporated into 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 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/newsscience/coating-personal-protection-equipment-252342/) The tough, multilayer coatings are made by sintering polytetrafluoroethylene (PTFE) nanoparticles in a solvent onto polypropylene microfibers 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.

On June 30, 2020, the SpecialChem website published a note regarding "New Hybrid Coatings to Protect Interior Walls from Microbial Contamination" based on polyacrylates that contain 3-(methacrylamino)propyltrimethylammonium chloride as a comonomer. The pendant quaternary ammonium groups act as biocidal centers:

A different approach is being pursued at Concordia University, Canada, and the Canada-wide research network based at Concordia. These are copper and titanium dioxide spray paints intended to prevent the spread of Covid 19:

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:
https://coatings.specialchem.com/news/industry-news/siegwerk-to-distribute-varcotecantimicrobial-coating-innovation-000221983?lr=ipc20061570&Ii=200165733&utm_source=NL&utm medium=EML&utm campai gn=ipc20061570&m i=NcWyxMS_lgE4uDtFR2SUvnvKpGP6scLXvpSt5WIN3KriGtDbdz%2Bxz VTOAM %2Bqw0%2BV%2B21wdqflul3qOabGieKUHdjkvRbBNp

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.

Aditya Kumar, Kalpita Nath and Poonam Chauhan from the Department of Chemical Engineering developed a superhydrophobic antiviral coating with self-cleaning properties based on silver nanoparticles irradiated with UV radiation and subsequently treated with perfluorodecyltriethoxysilane:

(See also SpecialChem for Coatings, Industry News, June 23, 2020). Because of the superhydrophobicity, however, the disadvantages described above are also to be expected here.

Yet another approach is followed by J. Mostaghimi of the University of Toronto, Canada. See "SpecialChem The material selection platform, September 7th, 2020", Twin-wire Arc Spray Technology to Deposit Cu on Fabrics):

and "Anti-viral copper coatings could help slow the transmission of COVID 19", Department of Mechanical & Industrial Engineering, University of Toronto, lynsey@mie.utoronto.ca; 8/31/2020. 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.

1. 1. Freisetzung von elektrischen Ladungen, meist Elektronen,
2. 2. Aufladung der Staubpartikel im elektrischen Feld oder Ionisator,
3. 3. Transport der geladenen Staubteilchen zu der Niederschlagselektrode
4. 4. Anhaftungen der Staubpartikel an der Niederschlagselektrode und
5. 5. Entfernung der Staubschicht von der Niederschlagselektrode.

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.

In the company publication of "LUFTREINIGERDEPOT your specialist for healthy indoor air",
https://www.luftreinigungdepot.de/gegen/bakterien-und-viren?p=1&o=2&n=20&f=784
downloaded on August 25th, 2020, the problems are clarified again (original quote at the beginning):

• "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 parcels, for other public spaces such as canteens, hairdressing 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 is due to the fact that it has not been around for long not been tested yet. 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 significantly reduce the concentration of viruses and bacteria in the air, they cannot completely prevent them. 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 (µm) 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.

From the Japanese patent application JP 2012-181008 A (machine translation) is known an air purification device comprising a Peltier element. The patent application shows an air purification device that can be operated by a temperature difference, having a vertical, tubular housing with a fan arranged in the floor area and an air inlet and an air outlet in the upper area, the air inlet channel and the air outlet channel in the housing being separated from one another by a vertical wall. The vertical partition has a Peltier element near the air inlet/air outlet, the hot side of which is in contact with the air inlet duct and preheats or warms the incoming air, and the cold side of which is in contact with the air outlet duct and cools the exhaust air. After heating the incoming air at the Peltier element, the air is cleaned at a catalyst heated by a PCT heating element and then deflected by the blower into the exhaust air duct, where it is cooled by the Peltier element before the air outlet. (see. 16 in conjunction with paragraph [0037]). In the known air purification device, the Peltier element is connected neither to a cooling ring on its cold side nor to a heat pipe and a heating plate on its hot side. In addition, no hangable cartridge with biocidal sorbents for air purification is provided. A thermal insulation of the housing is also not mentioned. In addition, the well-known air cleaning device is not mobile, but permanently installed.

From the German patent application DE 3103303 A1 another air cleaning device that can be operated by a temperature difference and has Peltier elements for heating/cooling the air and two cleaning stages of sorption and catalyst masses is known. The device consists of a horizontal housing with an air inlet and an air outlet, both located on the same side of the housing, and a series of Peltier elements dividing the housing horizontally into a heating zone and a cooling zone, with an air deflection he follows. Above the heating zone are two separately arranged chambers with the two cleaning stages, whereby the air is only slightly heated after entering the device at the first Peltier element, in order to then pass through the first chamber with the sorption masses and then through further heating to the to be heated to higher temperatures in the flow direction following further Peltier elements and then fed to the catalyst masses. After leaving the catalyst cleaning stage, the air flow is deflected and guided past the cold sides of the Peltier elements in the lower area of the housing. (Fig. in conjunction with para. [0020] -[0025]).

Japanese patent application JP H11-304 281 A1 (machine translation) describes an air purification device that can be operated by a temperature difference as an air conditioner with a Peltier element, which is arranged between two air supply ducts, the cold side being in contact with the cold air duct and the warm side being in contact with the warm air duct. Both air ducts are thermally separated from each other. Furthermore, the warm side of the Peltier element is provided with a carrier catalyst coating (porous glass film with embedded metals), so that air purification takes place on the warm air side at the same time. ( 1 in connection with claims 1-4).

The international patent application WO 2009/010528 A1 discloses a mobile air conditioner for heating/cooling with a fan and a replaceable air filter cartridge with biocidal granules as a bed between layers of gauze. In contrast to the subject of the application, however, the air filter cartridge is arranged in front of the heating/cooling system, with a Peltier element also being able to be provided in the case of air cooling. In addition, neither additional cooling devices nor thermal insulation of the housing are provided. ( 1 , 3 , 7 , 8th in connection with claims 1, 6-10, 16, 27 and page 3, line 25, to page 4, line 6, page 4, line 19 to page 5, line 29, page 6, line 20, to page 7, line 2) .

The German patent application DE 102 17 159 A1 shows an air cleaning device for cleaning breathing air with a vertical housing in which, after the air inlet, a heating chamber, a first bed of biocidal adsorber granules (spheres, cylinders with an active surface such as zeolites, molecular sieves + Ca, Mg aluminate), a separating sieve and a second Bed of a catalyst granules (made of metals) are arranged with a separate heater. The air is guided through an inner tube to the air outlet and cooled by heat exchangers before it is supplied as breathing air. ( 1 , 2 in connection with claims 1-5, 7-10 and paragraphs [0011]-[0013]). In this device, there is no insertable cartridge for the air-cleaning granules. In addition, the heating/cooling of the air is not carried out with a Peltier element in conjunction with a cooling line. There is also no provision for thermal insulation of the housing.

The German patent 10 2005 001 726 B4 shows another air purification device that can be operated with a temperature difference, in which the following assemblies are arranged one after the other in the direction of flow: a coarse filter made of stainless steel/aluminum with a coating of a thermoelectric material (e.g. bismuth), on which a voltage is applied to achieve thermoelectric cooling (= Peltier effect), a ceramic fine filter unit with catalytically active additives (e.g. metal-polymers with a biocidal effect) combined with a microwave radiator for heating the same, a control unit and a fan. ( 1 in connection with claims 10-15, para. [0021], [0030]). In this device, the Peltier element is used to cool the incoming air and this is only heated downstream by microwave radiation. In addition, neither a filter cartridge, a cooling circuit nor a thermal insulation of the housing are mentioned.

Object of the present invention

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

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 room air that can be operated by temperature difference was found according to independent patent claim 1, 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 23.

In addition, the method for cleaning and disinfecting room air using the device according to the invention according to claim 24 was found. The method is referred to below as the “method according to the invention”. Advantageous embodiments of the method according to the invention are the subject matter of dependent claims 25 to 27.

Furthermore, the use of the device according to the invention and the method according to the invention for eliminating free or aerosol-bound bacteria, viruses and other noxae in the air according to independent patent claim 28 was found. This use is referred to below as “use 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 and 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, 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.

A further significant advantage of the device according to the invention was that used virucidal and/or bactericidal fills and the adsorbents and absorbents of the cartridge to be used according to the invention could be decontaminated in a simple manner directly by mechanochemical processes in which harmful organic waste products were converted into carbon.

Because of their significantly smaller dimensions and 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 silently or almost silently. 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, stairwells and shops of all kinds.

In the floor area there is at least one space, in particular one space for inserting at least one rechargeable accumulator and an electronic control unit for regulating the air flow generated by the chimney effect through the cartridge described below.

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. In particular, the clear width for accommodating the components in the tubular outer wall is between 4.6 cm and 49.6 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 outline of the tubular outer wall is preferably square, hexagonal or octagonal. The connecting lines between the corners can be rectilinear or convexly bent outwards.

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, provided the latter do not increase the thermal conductivity λ to more than 80 W/(m.K).

Examples of suitable metals are chromium steel, high-alloy steel, low-alloy ferritic steel, unalloyed steel and titanium.

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 two peripheral separation points at which the outer wall can be disassembled and reassembled. These separation points are, in particular, plug connections or flange connections. The separation points facilitate assembly and maintenance of the device according to the invention.

The Peltier elements preferably have a circular, square or rectangular outline.

The number, size, shape, number of stages (single-stage or multi-stage) and power output of the Peltier elements can vary widely and depends primarily on the desired temperature difference between the hot and cold sides and the amount of air that is to be implemented during a unit of time, and thus according to the size of the device according to the invention. Those skilled in the art can easily select suitable, commercially available Peltier elements based on these specifications.

The hot sides of the Peltier elements are in thermally conductive contact with at least two, in particular four, vertical thermal lines of high thermal conductivity λ. The end areas are in turn in thermally conductive contact with the horizontal heating plate arranged on the floor area, which is heated by the hot sides of the vertical Peltier elements via the vertical heat pipes.

The at least two, in particular at least four, heat lines preferably have contact surfaces which are as large as the hot sides of the vertical Peltier elements. Below the contact surfaces, the heat lines can have smaller widths. The heat lines are preferably 0.2 cm to 1 cm, preferably 0.3 cm to 0.8 cm and in particular 0.13 cm to 0.7 cm thick. Their length depends basically on the dimensions of the device according to the invention and in particular on the height of the boiler room.

The circumferential cooling ring, the heating lines and the heating plates preferably have a thermal conductivity λ of 20 W/(m.K) to 430 W/(m.K). The components can be constructed from a wide variety of solid materials, as long as they have the desired thermal conductivity. Examples of suitable materials of this type are low-alloy ferritic steel, chromium steel, unalloyed steel, lead, titanium, tantalum, tin, platinum, iron, nickel, tungsten, zinc, brass, molybdenum, aluminium, aluminum alloys, gold, copper alloys, copper and silver.

Above the upper level of the heating platen are at least two, preferably at least four, opposed air inlets in the form of air ducts through the outer wall and through the thermal insulation coating. A grille can be attached to the air inlets at their inlet openings or a pre-filter can be installed to prevent larger parts from entering the boiler room.

The at least two, preferably at least four and in particular at least eight air tubes 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 be straight or curved so that the air enters the boiler room tangentially, creating turbulence in the incoming air that promotes heat transfer. The clear width of the cross section can expand in a funnel-like or horn-like manner from the inlet to the outlet. For better air guidance towards the inlet of the at least two air tubes, the outer wall can each have a correspondingly shaped air guiding groove. The walls of the at least two air tubes can be constructed from a wide variety of materials, with the materials described above having low thermal conductivity preferably being considered.

The horizontal Peltier elements are lateral, i. H. except for the contact surfaces with the heat pipes and the cooling ring, with a thermal insulation coating. The vertical heat lines are also covered with a thermal insulation coating, except for the contact surfaces with the horizontal heating plate. The remaining free vertical peripheral surface of the heating plate and its bottom are also covered with a thermal insulation coating. The inner surface of the outer tube also has a thermal insulation coating.

The thermal insulation coating preferably has a thermal conductivity λ of 0.001 W/(m.K) to 1.0 W/(m.K).

The thermal insulation coatings are preferably made from insulating paints selected from the group consisting of cork paints, silicone-based insulating paints open to diffusion, insulating paints with a high proportion of ceramic hollow spheres, insulating paints with aerogels, foam cement and insulating paints with microfine hollow glass beads.

Above the heating space above the heating plate is the replaceable cartridge described above, open at the top, with the thermally and electrically insulating cartridge wall, the air-permeable, sieve-like cartridge base, the openings of which are on the one hand so small that the beds described below cannot fall out, and the on the other hand are so large that the air resistance remains low.

In the embodiment in which the cartridge is in the form of a Venturi tube, there are (i) the bed of at least one type of particulate, inorganic, bactericidal and virucidal coated, inert carrier material and/or the bed of at least one type of particulate, inorganic and /or a particulate, inorganic, bactericidal and/or virucidal material and (ii) the bed of at least one type of particulate, inorganic and/or organometallic adsorbents and/or absorbents as a mixed bed.

This is advantageously achieved in that circumferential supports for air-permeable intermediate floors are attached to the inner wall of the cartridge, the openings of which are on the one hand so small that the fill cannot fall out and on the other hand are so large that the air resistance remains low. The intermediate bases are preferably constructed from the same material as the cartridge wall.

In the embodiment in which the cartridge is in the form of a Venturi tube, there are (i) the bed of at least one type of particulate, inorganic, bactericidal and virucidal coated, inert carrier material and/or the bed of at least one type of particulate, inorganic and /or a particulate, inorganic, bactericidal and/or virucidal material and (ii) the bed of at least one type of particulate particulate, inorganic absorbents and/or adsorbents as a mixed bed.

• - 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-linked SiO ₄ tetrahedrons. 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 that make up 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.

In Table 1 below, layered silicates are listed 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.

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.

The carrier material preferably has a thermal conductivity λ of 0.001 W/(m.K) to 1.0 W/(m.K).

The at least one type of particulate adsorbent and/or absorbent from the group consisting of spheres, hollow spheres, shards, granules, ground lumps, shards and granules, pellets, rings, spheres with core-shell structures, ellipsoids, cubes, Blocks, pyramids, cones, cylinders, rhombuses, dodecahedrons, truncated dodecahedrons, icosahedrons, truncated icosahedrons, dumbbells, tori, platelets, needles with circular, oval, elliptical, square, triangular, quadrilateral, 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 particulate adsorbents and / or absorbents selected.

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

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 of 0.5 cm to 10 cm, determined by sieve analysis.

According to the present invention, the particulate, inorganic, bactericidal and/or virucidal coated, inert carrier material has a coating which preferably has a thickness of 100 nm to 100 μm. The coating preferably has a contact angle θ with water of ≤90°. Without being bound to a theory, it is assumed that as a result aerosols wet the virucidal and/or bactericidal coatings better and the contact of the microorganisms contained therein, in particular the bacteria and/or viruses, with the biocides is intensified.

The coating contains at least one biocide, in particular at least one bactericide and/or virucide, in particular at least one pharmaceutical and/or disinfectant, which is or 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 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. 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 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 , dodecahedron, truncated dodecahedron, icosahedron, truncated icosahedron, dumbbell, tori, platelet, needle with circular, oval, elliptical, square, triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal or star-shaped cross-sections and/or in at least one direction of the space-curved shards, rings, dumbbells, tori, needles and discs. 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 that do not have a spherical shape is considered to be the longest distance laid through the microparticles.

The average diameter or the average particle size of the microparticles is preferably determined by light microscopy, dry sieving, wet sieving, Coulter Counter measurements or Fraunhofer scattering.

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.

• - das Lindquist-Hexamolybdatanion, Mo₆O₁₉ ^2-,
• - das Decavanadatanion, V₁₀O₂₈ ^6-,
• - das Paratungstatanion, H₂W₁₂O₄₂ ^10-,

• - die Weakley-Yamase- Struktur, XM₁₀O₃₆ ^n-, und
• - die Dexter-Silverton-Struktur, XM₁₂O₄₂ ^n-.

For example, the classification of the POM into the following structures is known:

• - the Lindquist hexamolybdate anion, Mo ₆ O ₁₉ ^2- ,
• - the decavanadate anion, V ₁₀ O ₂₈ ^6- ,
• - the paratungstate anion, H ₂ W ₁₂ O ₄₂ ^10- ,
• - Mo ₆ -polymolybdates, Mo ₃₆ O ₁₁₂ (H ₂ O) ^8- ,
• - the Strandberg structure, HP ₂ Mo ₅ O ₂₃ ^4- ,
• - the Keggin structure, XM ₁₂ O ₄₀ ^n- ,

• - the dilacunar Keggin structure,
• - the Wells-Dawson structure, X ₂ M ₁₈ O ₆₂ ^n- ,
• - the Anderson structure, XM ₆ O ₂₄ ^n- ,
• - the Allman-Waugh structure, X ₁₂ M ₁₈ O ₃₂ ^n- ,
• - 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: - (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), - (HSiW ₉ O ₃₄ ) ^9- (VI), - (HPW ₉ O ₃₄ ) ^8- (VII), - (TM) ₄ (PW ₉ O ₃₄ ) ^t - (VIII), - (TM) ₄ (P ₂ W ₁₅ O ₅₆ ) ₂ ^t - (IX), - (NaP ₅ W ₃₀ O ₁₁₀ ) ^14- (X), - (TM) ₃ (PW ₉ O ₃₄ ) ₂ ^12- (XI) and -( _P2W18O6 ^)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.

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 To spray gases such as methane, ethane, propane, butane, methylcyclohexane or gasoline, liquid nitrogen or liquid helium and to vaporize the dry ice or the 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), the lattice energy and symmetry of ionic liquids are reduced 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.

be described in detail. Express reference is made to the passages of the patent applications listed for the purpose of explaining the present invention in more detail.

Of the organic cations described above, imidazolium cations, in particular the 1-ethyl-3-methylimidazolium cation (EMIM) or the 1-butyl-3-methylimidazolium cation (BMIM), in which the quaternary nitrogen is in the 1st -position is used.

Suitable inorganic cations are all cations which do not form crystalline salts whose melting point is above 150° C. with the organic anions of the ionic liquids (C). Examples of suitable inorganic cations are the lanthanide cations.

Suitable inorganic anions are basically all anions which do not form crystalline salts with the organic cations of the ionic liquids (C), whose melting point is above 150° C., and which also do not have any undesirable interactions with the organic cations, such as chemical reactions enter.

The inorganic anions are preferably selected from the group consisting of halide, pseudohalide, sulfide, halometallate, cyanometallate, carbonylmetallate, haloborate, halophosphate, haloarsenate and haloantimonate anions and the anions of the oxygen acids of the halides, sulfur, nitrogen, phosphorus, carbon, silicon, boron and transition metals.

The POM anions listed above are particularly preferably used.

In the same way, suitable organic anions are basically all anions which do not form crystalline salts with the organic or inorganic cations of the ionic liquids, whose melting point is above 150° C. and which also have no undesirable interactions with the organic or inorganic cations how chemical reactions occur.

famous.

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 substances dissolved 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 and viruses.

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". 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 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 residues of cured 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. They can be crosslinked with amines, polyesters, phenolic resins, amino resins or polyisocyanates. 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.

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 more appropriate 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.

Particularly preferred reactive functional groups (S1) are therefore (meth)acrylate, ethacrylate, crotonate, cinnamate, vinyl ether, vinyl ester, dicyclopentadienyl, norbornenyl, isoprenyl, isopropenyl, allyl or butenyl groups; Dicyclopentadienyl, norbornenyl, isoprenyl, isopropenyl, allyl or butenyl ether groups or dicyclopentadienyl, norbornenyl, isoprenyl, isopropenyl, allyl or butenyl ester groups, but especially methacrylate groups (S 1).

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.

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.

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

The contact points in the thermal conduction system and the cold conduction system of the device according to the invention to intensify the thermal conduction preferably contain layers of a thermally conductive paste, in particular a graphite, nanocarbon, silver, diamond or aluminum nitride thermally conductive paste and/or AlN ceramic discs.

At least one rechargeable accumulator is built into the horizontal base of the device according to the invention as a power source for the at least one Peltier element. The at least one accumulator is pushed into a correspondingly shaped opening so that it can be removed again. It is connected to an electronic control unit in the horizontal floor to regulate the power output of the at least two Peltier elements.

The electronic control unit is preferably connected via signal lines to a miniature anemometer arranged in the upper opening of the cartridge and to a temperature sensor, as well as to a temperature sensor in the heating chamber. The electronic control unit regulates the air flow through the device according to the invention on the basis of the signals received from the sensors.

The front of the electronic control unit preferably includes a turning knob for switching on and for manual control, a socket for the plug of a charging cable, LEDs for indicating operation and a visual display showing the temperature difference between the temperature sensor in the opening of the cartridge and the temperature sensor in the boiler room.

Below the air-permeable cartridge base, an automatically or manually switchable axial fan with an electronically controlled electric motor with at least two blades can be attached horizontally as an auxiliary unit to a suspension in the second inner tube. In particular, Pope fans, such as those used to ventilate electronic devices, come into consideration as axial fans. The horizontal axial fan can be integrated into the electronic control system and can be activated when needed to start airflow through the cartridge. If the chimney effect then increases the airflow and keeps it running, the axial fan can be switched off automatically or manually.

The cartridge may also be stabilized by a circumferential, heat-resistant, low thermal conductivity supporting member Ä in the form of a funnel top for air directing. In addition, the cartridge can be stabilized by thermally insulating plugs, preferably made of heat-resistant elastomers, for vibration damping or with lateral horizontal extensions for vibration damping and flow blocking.

The device according to the invention can also stand on a support such as a horizontal plate with a larger cross-section or on sloping or straight legs. Your outside and the standing aids can be decorative, for example painted.

Feed 4 consisted of 191.7 parts by weight of n-butyl methacrylate, 153.4 parts by weight of styrene, 93.3 parts by weight of hydroxypropyl methacrylate, 424.9 parts by weight of hydroxyethyl methacrylate, 173.1 parts by weight of ethylhexyl methacrylate and 207.3 parts by weight of a 50 percent solution of tris(alkoxycarbonylamino) triazine (TACT®; crosslinking agent; see Table 3) in n-butanol. The reaction mixture was then polymerized for a further 2 h at 90° C. and then cooled.

The production of an organic-inorganic hybrid polymer dispersion as a coating material or coating agent

To 5.5 parts by weight of the boehmite sol described above was added 3.3 parts by weight of GLYEO. The reaction mixture thus obtained was stirred at room temperature for 90 min. Then 2.2 parts by weight of glycidyloxypropyltrimethoxysilane (GLYMO) were added. After stirring at room temperature for 2 hours, 0.55 part by weight of ethyl acetoacetate (EEA) was added, after which the resulting reaction mixture was stirred at room temperature for a further 2 hours. Then 0.75 part by weight of isopropanol was added. The resulting reaction mixture was stirred for 15 minutes, 1.25 parts by weight of the dispersion of the copolymer were added and the mixture was stirred at room temperature for a further 2 hours.

Die dünne, biozide und/oder viruzide Beschichtung enthielt, bezogen auf 1000 Gewichtsteile der Beschichtung, 2 Gewichtsteile Diuron: 3-(3,4-Dichlorphenyl)-1,1-dimethylharnstoff und 3 Gewichtsteile Quaternisiertes Chitosan (vg., A. Domard et al., „New method for the quaternization of chitosan“, International Journal of Biological Macromolecules, Band 8, Ausgabe 2, April, 1986, Seiten 105-107).

The coating system used was protected against electrostatic charges and had an extraction system. The uncoated, particulate, inorganic, inert carrier materials 5.2.1 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 supplied uncoated carrier materials 5.2.1 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 uncured liquid Layer formed on the carrier material, 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 heated - also with shaking - in a 5 m long continuous furnace cured at 110 ° C, so that the biocidal and / or virucidal coating formed on the carrier material 5.2.1. The shaking prevented the particles 5.2.1 from sticking together and/or sticking to the endless belt. If this did happen to a certain extent, the particles were separated in a 2 m long third station and then discharged into a storage vessel. Any residues of cured coating material adhering to the endless belt were scraped off with scrapers after the endless belt had been deflected.

• - As a coated carrier material 5.2.1, in a first embodiment, the granules of irregularly shaped foam glass gravel with a mean particle size determined by sieve analysis of 2 mm were thinly coated with the virucidal and bactericidal coating. The coating contained, based on 1000 parts by weight of the coating, 3.2 parts by weight 2-octyl-2H-isothiazol-3-one, 2.0 parts by weight, 1.0 part by weight zinc pyrithione and 2.0 parts by weight (±)-1-{[ 2-(2,4-dichlorophenyl)-4-propyl-1,3-dioxolane-2-yl]methyl}-H-1,2,4-triazole.

Domard et al., "New method for the quaternization of chitosan", International Journal of Biological Macromolecules, Volume 8, Issue 2, April, 1986, pages 105-107).

Coating Method 2 - General Rule

• - Als beschichtetes Trägermaterial 5.2.1 wurden bei einer ersten Ausführungsform die vorstehend beschriebenen Granulate aus unregelmäßig geformten Schaumglasschottern mit elektrischem Doppeldrahtsprühen Kupfer besprüht.
• - Bei einer zweiten Ausführungsform wurden die vorstehend beschriebenen gemahlenen Brocken aus Bimsstein verwendet, die ebenfalls mit Kupfer besprüht wurden.

• - In den vierten, fünften und sechsten Ausführungsformen wurden die Trägermaterialien 5.2.1 der ersten, zweiten und dritten Ausführungsformen nach dem analogen Verfahren mit Silber besprüht.

The coating system described in coating method 1 was modified in that, instead of a spray system for liquid coating materials, a spray system for electric double-wire spraying (twin-wire arc spraying) was used.

• - As a coated carrier material 5.2.1, the above-described granules of irregularly shaped foam glass gravel were sprayed copper with electric double-wire spraying in a first embodiment.
• - In a second embodiment, the ground lumps of pumice stone described above were used, which were also sprayed with copper.
• In a third embodiment, the glass Raschig rings described above were sprayed with copper.
• - In the fourth, fifth and sixth embodiments, the carrier materials 5.2.1 of the first, second and third embodiments were sprayed with silver using the analogous method.

In all cases, island-like and point-like, bactericidal and virucidal, highly effective, thin metal coatings resulted. Because of this type of coating, significant amounts of expensive biocidal metals could be saved without impairing the biocidal effect. In addition, a great deal of weight could be saved compared to a bed made of pure metal.

The devices according to the invention 1 - General description

In order to carry out the effectiveness tests, several devices 1 according to the invention were produced and filled with beds of the coated carrier materials 5.2.1 described above and the biocidal materials 5.2.2 as described below. Dried, platelet-shaped bentonite (sheet silicate, phyllosilicate) with an average particle size of 3 mm determined by sieve analysis was used as the adsorbent and/or absorbent.

The devices 1 according to the invention were 100 cm high from their base 1.7.1 to their upper ends 1.4. They had octagonal outer walls 1.1, each with two opposing vertical planar surfaces or sides, each with a horizontal outer diameter of 4 cm. The vertical planar surfaces were convex with curved surfaces each having a horizontal one Connected outer diameter of 5 cm. The outer walls 1.1 consisted of polished solid beech wood with a wall thickness of 0.8 cm. The outer walls 1.1 each had an upper horizontally encircling separation point 1.2 halfway up the outer walls 1.1 and a lower horizontally encircling separation point 1.3 above the air inlets 3 at the height of the heating rooms 2.1.6. Both separation points 1.2; 1.3 were made of plug-in connections. They served for easier assembly and easier maintenance of the devices 1 according to the invention. In the areas of the horizontal standing areas 1.7.1, the outer walls 1.1 were 1.5 cm thick. The floor areas 1.7 were 6 cm thick up to the horizontal inner floors 1.8 and had horizontal spaces 1.7.2 for the insertion of rechargeable accumulators 7 and electronic control devices 4. These components were pushed into the floor areas 1.7 on slide-in rails 1.7.3. The vertical inner walls 1.9 were 94 cm high. They and the horizontal inner floors 1.8 were coated with a 1 cm thick thermal insulation coating 2.1.4 containing an airgel thermal insulation paint.

The horizontal cross-sections formed by the outer walls 1.1 were thus octagons with a long axis A-B from outer wall to opposite outer wall of a length of 13 cm and an axis C-D transverse through the center of the axis A-B from outer wall to opposite outer wall of a length of 9.5 cm . Along the four flat sides ran the 4 cm wide, 88 cm long and 0.5 cm thick vertical flat heat pipes 2.1.1 made of an aluminum alloy with a thermal conductivity λ of 200 W/m.K), which at their upper end areas are in thermally conductive contact with the four Peltier elements 2 measuring 4 cm by 4 cm by 1.5 cm stood. In their lower end areas they were in thermally conductive contact with the 1.5 cm thick, octagon-shaped heating plates 2.1.2 made of the aluminum alloy. The heating plates 2.1.2 were placed on the thermal insulation coatings 2.1.4 on the horizontal inner floors 1.8. Between the contact points were thin layers of thermal paste containing carbon nanoparticles.

In the center of the heating plates 2.1.2 were 2 cm high heating and air deflection cones 2.1.3 each of which had a base diameter of 2 cm. The heating and air deflection cones 2.1.3 were integral parts of the heating plates 2.1.2.

The inner sides and upper ends of the heat pipes 2.1.1 and the three free side surfaces of the Peltier elements 2 and the surrounding vertical sides of the heating plates 2.1.2 were also coated with 1 cm thick thermal insulation coatings 2.1.4 from the thermal insulation paint listed above. This thermal insulation coatings 2.1.4 reached to the surfaces of the heating plates 2.1.2. Circumferential, heat-resistant, supporting components 5.5 made of the high-performance plastic polyethersulfone (PES) with a glass transition temperature of 225° C. and a thermal conductivity λ of 0.17 W/(m.K) stood on the heating plates. Components 5.5 were in the form of inverted funnel tops with an octagonal outline of 0.3 cm wall thickness and 2 cm height. They each stood on four 3 cm high legs 5.5.1 made of PES with a circular cross section and a diameter of 0.3 cm, which were spatially assigned to the four heat pipes 2.1.1.

The components 5.5 supported the air-permeable cartridge bases 5.3 with a wall thickness of 0.4 cm and bores with a clear width of 0.15 cm in the transition areas from the air-permeable cartridge bases 5.3 into the surrounding octagon-shaped cartridge walls 5 made of PES with a wall thickness of 0.4 cm away. The insides of the cartridges 5 were 81.5 cm high overall. At their upper ends, the cartridge walls 5.1 merged into peripheral octagon-shaped flanges as cartridge holders 5.4 with a wall thickness of 0.4 cm and a width of 3 cm, which rested on the horizontal thermal insulation coatings 2.1.4. The cartridges 5 had outer wall to opposing outer wall spacings along the long axes A-B of 7.7 cm. Along the short axes C-D they had outer wall to opposite outer wall distances of 4.2 cm.

1.4 cm below the upper openings 1.6 of the cartridges 5 were 2 cm high circumferential octagonal cooling rings 2.4 made of copper with a wall thickness of 0.4 cm, which were in thermally conductive contact with the cold sides 2.3 of the Peltier elements 2. To attach the cooling ring 2.4, the pre-products of the cartridges 5 produced by injection molding were cut at the appropriate points, and the cooling rings 2.4 were inserted and glued using a construction adhesive. The walls of the cooling rings 2.4 were connected to a wide-meshed grid of 1 mm thin copper wire struts 5.6. This significantly increased the cooling effect and thus the chimney effect.

In each of the four convexly curved surfaces of the outer walls 1.1 there were two tubular air inlets 3 made of PES with a circular one, slightly above the level of the heating plates 2.1.2 Cross-section of a wall thickness of 0.15 cm and a clear width of 1.5 cm. The tubular air inlets 3 ran horizontally through the thermal insulation coatings 2.1.4 between the heat pipes 2.1.1 into the boiler rooms 2.1.6. In the heating rooms 2.1.6 the incoming air was heated 3.1 and sucked with the help of the chimney effect as an air flow 3.2 through the permeable cartridge bases 5.3 and the cartridges 5 with the biocidal particulate cartridge fillings and through the upper openings 1.5; 1.6 decontaminated blown into the room air. The inlets themselves were sealed with pre-filters with a smallest filterable particle size of 1 µm to prevent coarse particles from entering.

The inside of the cartridge walls 5.1 each had two circumferential rings 0.3 cm horizontally protruding and 0.3 cm thick for supporting thin, air-permeable intermediate bases with bores with a clear width of 0.15 cm (not shown). The first intermediate floors were arranged 30 cm above the cartridge floors 5.3. The second shelves were 35 cm above the first shelves. As a result, three chambers were formed, of which the bottom one was filled with particulate, inorganic, bactericidal and virucidal, loose, air-permeable beds 5.2.2 made of irregularly shaped chunks of a mixture of lime and magnesium-calcium oxide in a weight ratio of 1:1 Mean particle size determined by sieve analysis was 2.5 mm. The second chambers were each filled with loose beds of one type of the above-described particulate, inorganic, bactericidal and virucidal coated, inert carrier materials 5.2.1. The top chambers were filled with loose beds of bentonite particles up to the upper openings 1.6 of the cartridges 5.

If necessary, filters 6 with different smallest filterable particle sizes could be inserted into the upper openings 1.5 of the devices 1.

A miniature anemometer and a temperature sensor (not shown) were located in the upper openings 1.6 of the cartridges 5, and a temperature sensor (not shown) was located in each of the heating chambers 2.1.6, which were connected to the electronic control units 4 were connected. As a result, the power output of the Peltier elements 2 and thus the temperatures in the heating plates 2.1.2 and the cooled openings 1.6 of the cartridges 5 and thus also the chimney effect and the strength of the air currents 3.2 could be regulated. The temperature differences between the lower and the upper temperature sensors could be read on the displays 4.4 of the electronic control units 4 and adjusted using the on and control buttons 4.1. In addition, the electronic control units 4 also contained light-emitting diodes 4.3 for the function display and a socket 4.2 for a charging cable for charging the accumulators 7.

As shown above, the construction according to the invention made it possible to realize the most diverse devices 1 according to the invention, which could be excellently adapted to the conditions of the individual case.

If the beds in the cartridges 5, in particular the beds of the absorbents and/or adsorbents, were so heavily contaminated by the decomposition products of the bacteria, viruses and virions after a very long period of use that it was necessary to exchange the materials, the contaminated beds could be removed by mechanochemical processes , as for example in the German Offenlegungsschrift DE 10 2019 006 084 A1 are described, processed. In these processes, the organic materials adsorbed and/or absorbed on and/or in the beds were converted into activated carbon. Due to its lower density, the activated carbon produced could be separated from the higher-density inorganic materials by sifting and used elsewhere. This was also another important advantage of the device 1 according to the invention and the method according to the invention.

Test of the effectiveness of the devices according to the invention 1

The effectiveness of the devices 1 according to the invention described above was tested using a test device. For this purpose, a device 1 according to the invention was placed in a correspondingly dimensioned, closed chamber. The outlet opening of the device 1 according to the invention was connected to a fume hood with an air outlet through which the exhaust air could be discharged. The transition from the device 1 according to the invention to the exhaust hood was sealed at the upper end with a circumferential seal. A solid cell-biological nutrient medium was placed on a previously sterilized film on an air-permeable carrier via a sluice in the hood. In the air duct was a laser diffraction particle counting sensor equipped with a Sig signal line was connected to a particle measuring device, and a sensor for flow measurement, which was connected to a signal line with a flow meter, arranged. Another sensor for particle counting was placed in the area of the air inlets of the respective device according to the invention and connected to another particle measuring device via a signal line. The two measuring devices and the measuring device sent the measurement signals to a central data processing system, where they were evaluated and displayed on a display device.

Before determining the effectiveness, the respective chamber 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 a connection, an automatically controlled shut-off valve and an air inlet nozzle. As soon as no more particle signals appeared on the display device, the flushing was ended by closing the shut-off valve, and aerosol clouds, which for safety reasons contained harmless intestinal bacteria such as Firmicutes, Bacteroidetes, Proteobacteria and Actinobateria, were discharged via an aerosol feed line, a blower, an open shut-off valve and a nebulization nozzle located inside the chamber at 23 ° C and 1.2 bar blown into the chamber, passed through the respective device 1 according to the invention and discharged via the hood and the air discharge.

In the fume hood, the exhaust air was blown directly onto the solid cell biological culture medium on the previously sterilized film.

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