Description

field of invention

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

Furthermore, the present invention relates to kits for assembling the mobile devices in different sizes.

In addition, the present invention relates to a method for cleaning and disinfecting room air using the mobile device.

Last but not least, the present invention relates to the use of the mobile device for killing microorganisms, specifically viruses and virions, which are collectively referred to below as viruses.

State of the art

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

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

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

• - High-performance particle filter (EPA = Efficient Particulate Airfilter), smallest filterable particle size: 100 nm,
• - Particle filter (HEPA = High Efficiency Particulate Airfilter), smallest filterable particle size: 100 nm,

• - Pre-filter, smallest filterable particle size: 1000 nm, and
• - Automotive cabin filter, smallest filterable particle size: 500 nm

be subdivided. 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.
• - Locking effect:
  • Smaller particles (particle size: 100 nm to 500 nm) that follow 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.
• - Inertial Effect:
  • Larger particles (particle size: 500 nm to >1 µm) do not follow the gas flow around the fiber, but collide with it due to their inertia and stick to it. This effect is also known 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). KW Lee and BYH Liu 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 to 381 , formulas that allow to calculate the minimum efficiency and MMPS for fiber filters due to the diffusion effect and the inertia effect. The results show that MMPS decreases with increasing filtration speed and fiber volume fraction and increases with increasing fiber size.

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

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

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

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

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

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

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

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

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

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

Filters based on membrane technology, in which foreign substances and pollutants are filtered out of the air by membranes and remain on the membranes, also have disadvantages, because the membranes have to be continuously cleaned with oxidizing agents if they are used for a long time. In addition, the used membranes are not reusable and must be disposed of, which is problematic.

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

downloaded on August 25th, 2020 the problems are clarified again (original quote at the beginning):

• "Air purifier against viruses 8 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 has not yet been tested due to the fact that it has not been around for long. Since it is not a completely new virus, but a mutated form of already known viruses, there is a lot to be said for its effectiveness.
• You can find out below which air purifiers are particularly suitable against bacteria and viruses.
• IMPORTANT NOTE:
• Please note that while air purifiers 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 aim for a complete cleaning of the room air up to 5 times per hour."

From the Korean patent specification KR 10 2012 008 1681 A a portable deodorizing device is known which allows the user to use alternating current and direct current alternatively. The device is easy to transport and carry. It includes a housing made of a plastic material. It also includes a control unit, a fan and a display unit. Inside the case there is an activated carbon filter to deodorize bad smells. The controller is located on one side of the case and controls the operation of the device. The fan is located on the housing to suck in the outside air before it is filtered through the activated carbon filter and released to the outside. The display unit displays the images input by the users and the operational status of the device. The activated carbon used is not specified in more detail.

From the American patent application U.S. 2018/0104374 A1 a photocatalytic filter is known comprising a permeable holder or base with internal chambers containing photocatalytic beads. The surfaces of the chambers are light-reflecting. Titanium dioxide, zinc oxide, cadmium sulfide, tungsten oxide or vanadium oxide is used as the photocatalytic material.

From the Chinese patent application CN 103073122 Type A is known as an air purification cabinet, which has a top cover, an air outlet, an air inlet, and a first UV sterilization lamp, a front filter screen, a high-energy ionic oxygen generation layer, an activated carbon particle layer, a second UV sterilization lamp, a glass fiber filter screen, a blower, and support legs. The air outlet is located at the top of the top cover, and the air inlet is located at the bottom of the air purification cabinet. The activated carbon used is not specified.
There are numerous other air filters of this type on the market, which in particular combine HEPA filters with activated carbon filters. However, this does not completely eliminate the disadvantages described above. In addition, UV-C emitters are therefore often used. Since UV-C radiation is harmful to humans and can cause skin cancer, among other things, handling these devices requires special care and precautions to prevent radiation leaks.

Another way to reduce the concentration of viruses 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.

Object of the present invention

The present invention was based on the object of proposing a mobile device for cleaning and disinfecting room air, which no longer has the disadvantages of the prior art, but allows contaminated room air to be permanently freed from a wide variety of noxae and microorganisms. In particular, the mobile device 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 biocides and the size of the devices.

Furthermore, the devices should be able to be produced in a simple manner with the aid of standardized kits and should mainly contain materials that are harmless to humans and animals.

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

Last but not least, the object of the present invention was to expand the application possibilities and the application-related potential of biochar beyond the previously known extent.

Last but not least, the use of the device according to the invention and the method according to the invention according to independent patent claim 20 was found, which 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 of the present invention was the basis of being able to be achieved with the aid of the device according to the invention, the method according to the invention, the kit according to the invention and the use according to the invention.

In particular, it was surprising that the device according to the invention and the method according to the invention no longer had the disadvantages of the prior art, but instead made it possible to permanently remove a wide variety of noxae and microorganisms from contaminated room air. In particular, the device according to the invention was able to 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 to absorb and/or absorb the resulting decomposition products adsorb.

This also meant that the volume of air that had to be circulated in order to achieve a lasting effect could be significantly reduced. 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 biocides, and the size of the devices.

Furthermore, the devices according to the invention could be manufactured in a simple manner using the kits according to the invention and contained only materials that were harmless to humans and animals.

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

In addition, the carbon footprint of the devices according to the invention was advantageously low and could be reduced to zero by using suitable materials such as wood, with longer operating times, by recycling and reusing used activated charcoal, in particular vegetable charcoal, and/or by producing terra preta.

Furthermore, the devices according to the invention could be part of furniture or used as lamps.

Last but not least, the possible applications and the technical potential of biochar have been expanded beyond what was previously known.

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 physiotherapeutic 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.

Examples of suitable fans are axial fans such as the well-known Pope fans from ebm-papst Mulfingen GmbH & Co. KG. The axial fans can be arranged side by side and/or in a row one behind the other in order to increase the suction and pressure effect. The EC radial modules - RadiCal® from ebm-papst Mulfingen GmbH & Co. KG are preferably used.

The axial fans can be equipped with devices for volume flow measurement using differential pressure gauges or a U liquid column. These can control and visualize the current volume flow during operation in the corresponding suction or pressure area

The device according to the invention also comprises a pressure area delimited by vertically aligned outer walls below the air outlet side of the at least one fan for the pressure build-up, at least one horizontally arranged container for particulate activated carbon which is flush with the inside of the outer walls and is air-permeable in the vertical direction and has at least one lower holder as well as an air outlet arranged underneath for the contaminated room air.

The essential component of the device according to the invention is activated charcoal, preferably vegetable charcoal, animal charcoal, animal waste charcoal, bone charcoal, and pyrogenic carbon of different degrees of pyrolysis, but especially vegetable charcoal.

In addition, the activated charcoal mass can be in the form of magnetisable, activated charcoal particles, such as those described in the German patent specification DE 10 2014 100 850 B4 , page 7, paragraph [0074] to page 8, paragraph [0084], and the German patent application DE 10 2014 100 849 A1 is described.

The biochar used with preference has an internal BET surface area of at least 300 m ² /g, particularly preferably at least 500 m ² /g and in particular at least 700 m ² /g. It has a high capillary density. Their pH is particularly preferably from 8 to 8.7. The H/C ratio is preferably <0.7, preferably <0.6 and in particular <0.5 according to the guideline of the European Biochar Certificate. An optimized biochar is described in the company publication of LUCRAT® GmbH, Energy-Dezentral 2018 / Eurotier.

The particulate activated carbons preferably have an average particle size determined by sieve analysis or a Sauter diameter of 3 mm to 16 mm, preferably 4 mm to 14 mm, particularly preferably 5 mm to 12 mm, particularly preferably 6 mm to 10 mm and in particular 6 mm to 8 mm . The activated carbon particles with such a Sauter diameter are optimally balanced in terms of effective surface area on the one hand and air resistance on the other.

In a preferred embodiment, at least one container that is only air-permeable in the vertical direction contains a particulate activated carbon that is homogeneously mixed with at least one particulate ferromagnetic material.

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- ,
• - Moss 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 double Keggin structure,
• - the Keggin sandwich structure,
• - the monolacunar Keggin structure,
• - 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 power n is an integer from 3 to 20 denotes the valence 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. Aquatic 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.

Examples of suitable cations are

• - monovalent cations such as hydrogen, lithium, sodium, potassium, rubidium, cesium, cuprous and silver ions;
• - divalent cations such as magnesium, calcium, strontium, barium, copper (II), iron (II), nickel, cobalt, tin (II) and zinc ions;
• - trivalent cations such as aluminum, ferric, lanthanide and actinide ions;
• - tetravalent cations such as lead (IV) cations;
• - mono-, di-, tri- or tetra-(C ₁ -C ₂₀ -alkylammonium) such as pentadecyldimethylferrocenylmethylammonium, undecyldimethylferrocenylmethylammonium, hexadecyltrimethylammonium, octadecyltrimethylammonium, didodecyldimethylammonium, ditetradecyldimethylammonium, dihexadecyldimethylammonium, dioctadecyldimethylammonium, dioctadecylviologen, trioctadecylmethylammonium and tetrabutylammonium;
• - Mono-, di-, tri- or tetra-(C ₁ -C ₂₀ -alkanoiammonium) such as ethanolammonium, diethanolammonium and triethanolammonium; and
• - Monocations of naturally occurring amino acids such as histidinium (HISH ⁺ ), argininium (ARGH ⁺ ) or lysinium (LYSH ⁺ ) or oligo- or polypeptides with one or more protonated basic amino acid residue(s).

[See. e.g. US 6,020,369, column 3, line 6 to column 4, line 29]

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

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

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

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

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

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

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

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

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

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

In particular, the heterocyclic quaternary ammonium cations are selected from the group consisting of pyrrolium, imidazolium, 1H-pyrazolium, 3H-pyrazolium, 4H-pyrazolium, 1-pyrazolinium, 2-pyrazolinium, 3-pyrazolinium, 2,3-dihydro-imidazolinium, 4,5-dihydro-imidazolinium, 2,5-dihydro-imidazolinium, pyrrolidinium, 1,2,4-triazolium (quaternary nitrogen 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.

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 containers for the activated charcoal that are only air-permeable in the vertical direction are metal wire meshes, plastic wire meshes and/or textile meshes with a mesh size that on the one hand prevents the particulate activated charcoal from falling out and on the other hand does not cause excessive air resistance. The containers each have a vertical, circumferential, fitting, airtight wall made of metal, plastic or textile. This ensures that the air only flows through the beds of particulate activated carbon and not between the inside of the vertically aligned outer walls and the containers.

However, it is also possible for the outer walls to have transparent areas or windows, behind which the lighting fixtures can be placed so that their light shines outwards. White and/or colored LEDs and/or fluorescent tubes are preferably used as lighting elements. The transparent areas or windows can consist of clear, colored, and/or clouded glasses and/or plastics and/or cut stone slabs.

This expands the application possibilities of the device according to the invention in an advantageous manner.
