Infrarotstrahler zur thermischen Behandlung von Gütern, nämlich Baukörpern, Bauelementen und BaustoffenInfrared emitters for the thermal treatment of goods, namely structures, building elements and building materials
Die Erfindung betrifft Infrarotstrahler mit selektiven transformierten Infrarot (STIR) für die thermische Behandlung von Baukörpern, Bauelementen und Baustoffen, nämlich zum Trocknen, Heizen, Entkeimen und Sterilisieren.The invention relates to infrared radiators with selective transformed infrared (STIR) for the thermal treatment of structures, components and building materials, namely for drying, heating, sterilizing and sterilizing.
Nach DE 101 63 087 sind Infrarotstrahler in Modulbauweise ausgeführt, und zwar als Stabstrahler mit Reflektor oder als Flachstrahler ohne Reflektor. Stabstrahler besitzen einen Keramikträger mit innenliegenden Kern, der Kapillaren für die Aufnahme mindestens einer Heizeinrichtung aufweist. Auf dem Keramikträger ist eine Keramikschicht als Funktionskeramik befindlich. Stabstrahler sind sinnvollerweise mit einem Reflektor ausgestattet. Je nach Einsatzaufgabe und Verwendungszweck sind bestimmte Werte für Emitterdurchmesser, Reflektoröffnung, Reflektorhöhe, Emitterlänge, Emitterleistung im Verhältnis zur Emitterlänge und Emitterleistung im Verhältnis zur Fläche realisiert.According to DE 101 63 087, infrared radiators are designed in a modular design, specifically as rod radiators with reflectors or as flat radiators without reflectors. Rod heaters have a ceramic carrier with an internal core that has capillaries for holding at least one heating device. A ceramic layer as functional ceramic is located on the ceramic carrier. Rod spotlights are usefully equipped with a reflector. Depending on the application and intended use, certain values for emitter diameter, reflector opening, reflector height, emitter length, emitter power in relation to the emitter length and emitter power in relation to the area are realized.
Ein Flachstrahler besteht aus einem Gehäuse mit Seitenflächen und einem Boden. Das Gehäuse ist von der Bodenseite aus betrachtet schichtweise mit einer thermischen Isolierung, einem Energiesystem, einem Keramikträger und einer Funktionskeramik ausgefüllt. Es nimmt somit alle erforderlichen Baugruppen sicher und stabil auf. Die Infrarotstrahlen treten an der dem Gehäuseboden gegenüberliegenden Seite aus.A flat radiator consists of a housing with side surfaces and a base. When viewed from the bottom, the housing is filled in layers with thermal insulation, an energy system, a ceramic carrier and a functional ceramic. It therefore holds all the necessary assemblies safely and stably. The infrared rays emerge on the side opposite the housing base.
Ursprünglich war vorgesehen, diese Strahler in Maschinen, Geräten und Anlagen der Lebensmitteltechnik einzusetzen und somit zum Garen, Backen, Rösten, Trocknen und anderweitigen thermischen Behandeln von Lebensmitteln zu verwenden. Durch unerwartet eingetretene Naturereignisse in Form von Starkregen und Hochwasser bestimmter Flüsse ist der Bedarf an Sanierungs- bzw. Werterhaltungskapazitäten für Bauwerke, Bauelemente und Baustoffe sprunghaft angestiegen. Zur Befriedigung dieses Bedarfs standen im Wesentlichen nur konventionelle Trocknungsverfahren mittels Konvektionswärmegeräten,Originally it was planned to use these heaters in machines, devices and systems in food technology and thus to use them for cooking, baking, roasting, drying and other thermal treatment of food. Due to unexpected natural events in the form of heavy rain and flooding of certain rivers, the need for renovation and maintenance capacities for buildings, components and building materials has skyrocketed. To meet this need, there were essentially only conventional drying processes using convection heating devices,
Ventilatoren und Luftentfeuchtern zur Verfügung. Daneben sind im geringen Maße seltene Verfahren und Techniken mit Mikrowellen, Infrarot und Radiowellen bekannt. Die klassischen Verfahren und die Verfahren mit Radiowellen haben den Nachteil, dass die Trocknung in der Regel außerordentlich zeitaufwendig ist. Die Trocknungszeiten liegen im Bereich von 100 bis 1000 Tagen. Der Nachteil der Mikrowellentechnik liegt in der Gefahr der Zerstörung des Bauwerks, der Schädigung von im Mauerwerk verlegten Kabeln, Rohrleitungen und dgl. sowie in der Gesundheitsgefahr für den Bediener. Vereinzelt bekannt gewordene Infrarotlösungen sind wenig effektiv. Daher wäre ein Trocknungsverfahren wünschenswert, das diese Nachteile nicht aufweist.Fans and dehumidifiers are available. In addition, rare processes and techniques with microwaves, infrared and radio waves are known to a small extent. The classic methods and the methods with radio waves have the disadvantage that drying is usually extremely time-consuming. The drying times range from 100 to 1000 days. The disadvantage of microwave technology lies in the risk of destruction of the building, damage to cables, pipelines and the like laid in the masonry, and the health hazard for the operator. Sporadically known infrared solutions are not very effective. Therefore, a drying process that does not have these disadvantages would be desirable.
Aufgabenhaft waren daher Verfahrens- und vorrichtungsseitig schnell praxisverfügbare Lösungen zu finden und entsprechend wirksam umzusetzen.Process and device-side solutions therefore had to be found quickly and practically effective.
Erfindungsgemäß werden Verwendungsmöglichkeiten der erwähnten Stab- und Flachstrahler nach DE 101 63 087, die selektiv transformiertes Infrarot (STIR) emittieren, für die thermische Behandlung von Baukörpern, Bauelementen und Baustoffen gemäß Hauptanspruch 1 vorgeschlagen. In den Unteransprüchen sind zweckmäßige Ausgestaltungen angegeben.According to the invention, possible uses of the aforementioned rod and flat radiators according to DE 101 63 087, which emit selectively transformed infrared (STIR), are proposed for the thermal treatment of structures, components and materials according to main claim 1. Appropriate configurations are specified in the subclaims.
Unter thermischer Behandlung wird Trocknen, Heizen, Entkeimen und Sterilisieren verstanden, und zwar je nach Bedarf bezogen auf frische, dauerfeuchte bzw. durch Wassereinbruch geschädigte Baukörper und die darin verwendeten Bauelemente und Baustoffe, gegebenenfalls auch Lebewesen und leicht verderbliche Güter. Unter die Anwendungsstoffe fallen auch jeweils frisch verarbeitete Estriche, MörteJUPuize und Farben, wie auch Beton.Thermal treatment is understood to mean drying, heating, sterilizing and sterilizing, depending on the need in relation to fresh, permanently moist or water-damaged structures and the components and building materials used therein, possibly also living beings and easily perishable goods. The application materials also include freshly processed screeds, mortar JUPuize and colors, as well as concrete.
Im Wesentlichen werden Strahler eingesetzt, die den Konstruktionsprinzipien nach DE 101 63 087 folgen und den technologischen Prinzipien für das Trocknen imEssentially, emitters are used which follow the construction principles according to DE 101 63 087 and the technological principles for drying in
Allgemeinen gemäß DE 101 32535 genügen, wobei hier von biologischen Trocknungsmaterial ausgegangen wird. Die eingesetzten Strahler basieren in Bezug auf die Werkstoffprinzipien auf einen Emitter zur Infrarotbestrahlung von biologischen Material nach der deutschen Patentanmeldung 102 17011.8. Aus der Verwendung im Bausektor, wie oben beschrieben, ergeben sich gegenüber der bisher üblichen Praxis folgende kennzeichnende Merkmale:Generally sufficient according to DE 101 32535, here biological drying material is assumed. With regard to the material principles, the emitters used are based on an emitter for infrared radiation of biological material according to German patent application 102 17011.8. Use in the construction sector, as described above, has the following characteristic features compared to the usual practice:
- Hohe Emissionswerte an Infrarot bis 95 %;- High emission values of infrared up to 95%;
- Gezielte und eingeengte Bandbreite der Emission auf die beabsichtigte Absorption der zu behandelnden Güter (OH-Gruppen, CH-Gruppen, Andere); - Differenzierte Anwendung, beispielsweise bei Lebensmitteln und Futter;- Targeted and narrowed range of emissions to the intended absorption of the goods to be treated (OH groups, CH groups, others); - Differentiated application, for example in food and feed;
- Große Bandbreite der STIR- Intensität von 1 bis 100 kW/m2;- Wide range of STIR intensity from 1 to 100 kW / m 2 ;
- Große Bandbreite der möglichen Emittertemperatur von 100 bis 1.500 °C;- Wide range of possible emitter temperatures from 100 to 1,500 ° C;
- Große Bandbreite der möglichen Oberflächentemperatur des Behandlungsmaterials von 0 bis 1.000 °C.- Wide range of possible surface temperatures of the treatment material from 0 to 1,000 ° C.
Zum Trocknen ist der Strahler vorzugsweise im Abstand 20 bis 400 mm vertikal, horizontal oder in einen definierten Winkel auf die feuchten Flächen des Behandlungsmaterials ausgerichtet, wobei ein ausreichend großes Partialdruckgefälle einzustellen ist. Unter dem im Folgenden Begriff verwendeten Begriff Behandlungsmaterial werden, wie bereits erwähnt, insbesondere feuchte Bauwerke und die darin befindlichen bzw. einzusetzenden Elemente und Stoffe verstanden, beispielsweise ganze Gebäude, Räume, Wände, Fußböden, Balken, Türen, Treppen, wie auch Estrich, Mörtel, Putz oder Beton in ausgehärteter und frischer Form, gegebenenfalls auch Lebewesen und leicht verderbliche Güter. Die Trockenzeit hängt ab vom Grad der Durchfeuchtung, der Art der Behandlungsmaterialien, deren Dicke, der Intensität des Infrarots und vom Partialdruckgefälle zwischen der Feuchte auf der Oberfläche des Behandlungsmaterials und der Feuchte der umgebenden Luft. Das mit speziellen Keramikemittern erzeugte selektiv transformierte Infrarot mit einer Energiedichte von 1 bis 10 kW/m2 dringt in die äußere Schicht des Behandlungsmaterials ein. Dort wandelt es sich in Wärme im Temperaturbereich von 30 bis 120 °C um. Im Bereich des Eindringens erfolgt die Liquidierung von Pilzen und Bakterien. Die erzeugte Wärme wird auf Grund der Wärmeleitfähigkeit des Wassers und desFor drying, the radiator is preferably aligned at a distance of 20 to 400 mm vertically, horizontally or at a defined angle to the moist surfaces of the treatment material, with a sufficiently large partial pressure drop to be set. As already mentioned, the term treatment material used in the following term in particular means damp structures and the elements and substances located or to be used therein, for example entire buildings, rooms, walls, floors, beams, doors, stairs, as well as screed and mortar , Plaster or concrete in hardened and fresh form, possibly also living things and easily perishable goods. The drying time depends on the degree of moisture penetration, the type of treatment materials, their thickness, the intensity of the infrared and the partial pressure drop between the moisture on the surface of the treatment material and the humidity of the surrounding air. The selectively transformed infrared generated with special ceramic emitters with an energy density of 1 to 10 kW / m 2 penetrates into the outer layer of the treatment material. There it converts to heat in the temperature range from 30 to 120 ° C. In the area of penetration, fungi and bacteria are liquidated. The heat generated is due to the thermal conductivity of the water and
Behandlungsmaterials weiter in die Tiefe fortgeleitet. Eindringtiefe und -geschwindigkeit sind von folgenden Faktoren abhängig:Treatment material forwarded further down. The depth and speed of penetration depend on the following factors:
- Feuchtegrad des Behandlungsmaterials;- Degree of moisture of the treatment material;
- Art und Beschaffenheit, insbesondere Dicke, des Behandlungsmaterials; - Temperatur auf der Außenseite des Behandlungsmaterials;- Type and nature, in particular thickness, of the treatment material; - temperature on the outside of the treatment material;
- Wassermenge auf der Außenseite des Behandlungsmaterials, zum Beispiel von außen anliegender Grundwasserspiegel.- Amount of water on the outside of the treatment material, e.g. groundwater level from the outside.
Die erhöhte Temperatur im Inneren des Behandlungsmaterials führt zur beschleunigten Verdampfung des Wassers. Der Wasserdampf wird über die vorhandenen Kapillaren, Risse o.a. in Richtung des Strahlers nach außen abgeführt und von Umgebungsluft aufgenommen.The increased temperature inside the treatment material leads to accelerated evaporation of the water. The water vapor is removed via the existing capillaries, cracks or similar. discharged in the direction of the radiator and absorbed by ambient air.
Die Aufnahmefähigkeit ist um so größer, je größer das Gefälle des Partialdrucks ist. Bei Kombination von STIR in Verbindung mit Elektroosmose, beispielsweise mit dem System AQUAMAT , oder mit Entfeuchtern, kalter und trockener Luft oder anderen geeigneten Techniken kann die Wirksamkeit noch verstärkt werden.The greater the gradient of the partial pressure, the greater the absorption capacity. When STIR is combined with electroosmosis, for example with the AQUAMAT system, or with dehumidifiers, cold and dry air or other suitable techniques, the effectiveness can be increased even further.
Beim Trocknen des Behandlungsmaterials, insbesondere auch von Estrich, Mörtel, Putz, Farben oder Beton, ist ein energiesparendes, schonendes und beschleunigtes Verfahren mit Entkeimungs- und Sterilisierungseffekt realisierbar, das bis in tiefere Schichten wirkt. Somit sind wesentlich kürzere Bauzeiten möglich. Außerdem sind bereits verlegte Kabel, Leitungen, elektrische und sanitäre Bauelemente nicht gefährdet.When drying the treatment material, especially screed, mortar, plaster, paint or concrete, an energy-saving, gentle and accelerated process with disinfection and sterilization effect can be realized, which works down to the deeper layers. This means that considerably shorter construction times are possible. In addition, cables, lines, electrical and sanitary components that have already been laid are not endangered.
Zum Heizen sind die verwendeten Strahler nicht direkt gegen eine Fläche, sondern in das Innere eines zu erwärmenden Raumes oder in Richtung des Aufenthaltsbzw. Bewegungsbereiches von Personen, Tieren und/oder Objekten gerichtet, und zwar mit vertikaler, horizontaler oder winkliger Ausrichtung. Die eingesetzten keramischen Infrarot- Heizstrahler wirken ähnlich wie ein konventioneller Kachelofen. STIR dringt rasch und effektiv in die Oberfläche des Subjekts oder Objektes ein und sorgt so für Mensch oder Tier für ein wohltuendes gesundheitsförderndes Wärmeempfinden. Gegebenenfalls kann die Erwärmung noch zusätzlich mit Konvektionswärme unterstützt werden. Die empfohlene STIR- Leistung beträgt zweckmäßigerweise 0,2 bis 8 kW/m2. Die Strahlertemperatur liegt zwischen 50 und 500 °C. Der Aufstellungsabstand zum Subjekt oder Objekt sollte wenigstens 0,2 m betragen und auf maximal 8 m erweiterbar.For heating, the radiators used are not directly against a surface, but in the interior of a room to be heated or in the direction of the place of stay. Movement range of people, animals and / or objects directed, with vertical, horizontal or angled orientation. The ceramic infrared heaters used have a similar effect to a conventional tiled stove. STIR penetrates quickly and effectively into the surface of the subject or object, thus ensuring a beneficial, health-promoting warmth sensation for humans or animals. If necessary, the heating can also be supported with convection heat. The recommended STIR output is expediently 0.2 to 8 kW / m 2 . The heater temperature is between 50 and 500 ° C. The installation distance to the subject or object should be at least 0.2 m and expandable to a maximum of 8 m.
Das Verfahren besitzt eine hohe Wirtschaftlichkeit gegeben, die darin begründet ist, dass die Strahler ohne lange Vorheizzeit bereits kurz nach dem Einschalten aktiv sind und dass diese nur die gewünschten partiellen Bereiche und nicht das gesamte Luftvolumen des Raumes erwärmen. Gegenüber konventionellen Verfahren sind dadurch Energiekosteneinsparungen erzielbar.The process has a high level of economy, which is due to the fact that the radiators are active shortly after being switched on without a long preheating time and that they only heat the desired partial areas and not the entire air volume of the room. Compared to conventional processes, energy cost savings can be achieved.
Beim Entkeimen von Räumen mittels spezieller keramischer Infrarotstrahler mit selektiv transformierten Infrarot nach DE 101 63 087 werden Pilze und Bakterien, die in der umgebenden Luft vorhanden sind, liquidiert. Dazu ist der Infrarotstrahler vorteihafterweise unter der Decke mit Strahlrichtung nach oben angebracht. Die meisten in der Luft befindlichen Pilze und Bakterien werden auf Grund der natürlichen oder durch geeignete Maßnahmen herbeigeführten Luftzirkulation in die Nähe des Infrarotstrahlers gebracht und durch erhöhter Wärmeeinwirkung vernichtet. Der Einsatz empfiehlt sich insbesondere in Räumen mit hohen Konzentrationen an Menschen, Tieren, Lebensmitteln und anderen Bioprodukten. In der Regel sind hier die Möglichkeiten der Entstehung, Ausbreitung und Übertragung von Keimen sehr hoch. STIR verringert Ansteckungs- und Infektionsgefahren für Mensch und Tier beispielsweise in Klassenräumen, Wartezimmern, Operationsräumen,When rooms are disinfected using special ceramic infrared radiators with selectively transformed infrared according to DE 101 63 087, fungi and bacteria that are present in the surrounding air are liquidated. For this purpose, the infrared heater is advantageously mounted under the ceiling with the beam direction upwards. Most of the fungi and bacteria in the air are brought into the vicinity of the infrared radiator due to the natural or suitable air circulation and are destroyed by increased heat. Its use is particularly recommended in rooms with high concentrations of people, animals, food and other organic products. As a rule, the possibilities for the emergence, spread and transmission of germs are very high. STIR reduces the risk of infection and infection for humans and animals, for example in classrooms, waiting rooms, operating rooms,
Personentransportmitteln aller Art, Ställen und dgl. und dämmt die Entstehung und Ausbreitung von Fäulnis und Keimen in Lagerräumen für Obst, Gemüse, Kartoffeln oder Futtermitteln ein.Passenger means of transport of all kinds, stables and the like, and contain the development and spread of putrefaction and germs in storage rooms for fruit, vegetables, potatoes or animal feed.
Schließlich sind Infrarotstrahler nach DE 101 63 087 zum Trocknen und thermischen Bearbeiten, unter anderem Aufschäumen, von Baustoffen aller Art, beispielsweise Gipserzeugnissen, Fliesen, Holz und Holzerzeugnissen, Spezialbaustoffen oder Spezialkeramiken, einsetzbar.Finally, infrared radiators according to DE 101 63 087 can be used for drying and thermal processing, including foaming, of all kinds of building materials, for example plaster products, tiles, wood and wood products, special building materials or special ceramics.
