Beschreibung:Description:
Spezieller Mikrowellenapplikator (Mikrowellenantenne ausgebildet als Pyramidenhorn oder Hohlleiter mit Schlitzen) mit Schutzfenster, Dichtwulst, Luftabsaugvorrichtung und Reflexionsfolie, zur Mikrowellenerwärmung von Objekten mit geringer Feuchtigkeit.Special microwave applicator (microwave antenna designed as a pyramid horn or waveguide with slots) with protective window, sealing bead, air extraction device and reflective foil, for microwave heating of objects with low moisture.
Für die Aufgabe der zerstörungsfreien Schadstoffsanierung werden gegenwärtig u.a. Methoden und Geräte auf der Basis von thermischen Verfahren und deren Kombination entwickelt. Die Verwendung von Mikrowellen (vorrangig mit Frequenzen aus dem ISM-Band) hat den Vorteil, daß die thermische Mobilisierung von Schadstoffen auch mit hoher Tiefenwirkung im Objekt erfolgen kann.For the task of non-destructive pollutant remediation, methods and devices based on thermal processes and their combination are currently being developed. The use of microwaves (primarily with frequencies from the ISM band) has the advantage that the thermal mobilization of pollutants can also take place with a great depth effect in the object.
Der Einsatz der Mikrowellentechnik basiert auf dem physikalischen Effekt der durch die Mikrowelle zum Schwingen angeregten Moleküle mit Dipolcharakter (Wasser) und der damit verbundenen Temperaturerhöhung des Materials. Bisher wurde daher die Mikrowelle primär zur Trocknung von feuchten Materialien und von Bausubstanz eingesetzt.The use of microwave technology is based on the physical effect of molecules with dipole characteristics (water) being excited to vibrate by the microwave and the associated increase in the temperature of the material. Up to now, microwaves have therefore been used primarily to dry damp materials and building materials.
Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, eine Möglichkeit zu besitzen, mit der durch die gerichtete Mikrowellenanwendung Schadstoffe auch bei Objekten mit geringer Feuchtigkeit thermisch mobilisiert sowie kostengünstig und gefahrlos entsorgt werden können.The invention specified in the protection claim is based on the problem of having a possibility with which pollutants can be thermally mobilized and disposed of cost-effectively and safely even in objects with low moisture levels by means of the directed application of microwaves.
Dieses Problem wird mit den im Schutzanspruch aufgeführten Merkmalen gelöst.This problem is solved with the features listed in the protection claim.
Der Applikator kann entgegen bekannten Lösungen durch Verbindung mit der hinter dem Objekt eingesetzten leitfähigen Folie auch zur Erwärmung trockener Bausubstanz eingesetzt werden und somit vorhandene Schadstoffe thermisch mobilisieren. Die Erfindung ist geeignet, ohne Einschränkungen an allen Standartgeneratoren eingesetzt werden zu können und dabei durch konstruktive Skalierung optimal an die zu bearbeitenden Flächen anpassbar.Contrary to known solutions, the applicator can also be used to heat dry building materials by connecting it to the conductive foil placed behind the object, thus thermally mobilizing existing pollutants. The invention is suitable for use with all standard generators without restrictions and can be optimally adapted to the surfaces to be treated thanks to structural scaling.
Durch diese Lösung werden hohe Energieumwandlungsraten erzielt, wodurch auch die Effektivität bei der Trocknung feuchter Bausubstanz gesteigert werden kann, da im Gegensatz zu bekannten Lösungen weniger Energie durch Transmission und schädliche Reflexion im Generator verloren geht.This solution achieves high energy conversion rates, which can also increase the effectiveness of drying damp building materials, since, in contrast to known solutions, less energy is lost through transmission and harmful reflection in the generator.
Durch die in der Figur 1 gezeigte konstruktive Gestaltung und den beschriebenen Einsatz des Applikators wird ein Unterdruck im erwärmten Oberflächenbereich erzeugt und so die Effektivität bei der Entfernung von Schadstoffen als auch von Feuchtigkeit effektiviert.The structural design shown in Figure 1 and the use of the applicator described generate a negative pressure in the heated surface area, thus increasing the effectiveness in removing pollutants as well as moisture.
Die in der beschriebenen konstruktiven Ausführung vorgenommene Anbringung der Abdichtung am Applikator gewährleistet neben der Abdichtung den gleichbleibenden optimalen Abstand zwischen Applikator und Objekt.The attachment of the seal to the applicator in the described design ensures not only the seal but also the constant optimal distance between the applicator and the object.
Der spezielle Applikator ermöglicht es, im Gegensatz zu bekannten Lösungen schädliche Dämpfe und/ oder Feuchtigkeit einfach und sicher unter Umgehung aufwendiger Schleusenkonstruktionen zu eliminieren, ohne den Arbeitsbereich zu kontaminieren.In contrast to known solutions, the special applicator makes it possible to eliminate harmful vapors and/or moisture easily and safely, bypassing complex lock constructions and without contaminating the work area.
Die Ausführung der Erfindung wird anhand der Figur 1 erläutert. Sie zeigt die Darstellung des Aufbaus der Vorrichtung bei der Anwendung.The embodiment of the invention is explained with reference to Figure 1. It shows the structure of the device during use.
