Description
Die Erfindung betrifft eine UV-Strahlenquelle mit den Merkmalen des Oberbegriffs des Anspruchs 1 und Verwendungen einer UV-Strahlenquelle mit den Merkmalen des Oberbegriffs des Anspruchs 7.The The invention relates to a UV radiation source with the features of The preamble of claim 1 and uses of a UV radiation source with the features of the preamble of claim 7.
Bei der gewerblichen Herstellung von Lebensmitteln oder auch in Klimaanlagen werden UV-Strahlenquellen zur Entkeimung eingesetzt, wobei die Bestrahlung von Lebensmitteln an sich nur für Obst- und Gemüseprodukte zulässig ist und ansonsten im Wesentlichen Packstoffe, Maschinenteile, Oberflächen oder Luft bestrahlt werden. Die UV-Strahlenquellen sind im Allgemeinen in einer Glashülle enthalten und bestrahlen aus unmittelbarer Nähe, z. B. die o. g. Lebensmittel und/oder deren Zubereitungseinrichtungen, oder aus größerem Abstand, z. B. als Deckenarmatur zur Luft- und Oberflächenentkeimung, wobei die Wirksamkeit der UV-Strahlenquellen für die Entkeimung wesentlich vom ungehinderten Zugang der UV-Strahlen zu der zu entkeimenden Sache abhängt. Nachteilig ist, dass im Betrieb beim Bruch der Glashülle einer UV-Strahlenquelle Glassplitter in die Lebensmittel gelangen können. Sicherheitsvorrichtungen gegen Glassplitter hindern den Zugang der UV-Strahlen zu der zu entkeimenden Sache.at the commercial production of food or even in air conditioners UV radiation sources are used for sterilization, whereby the irradiation foodstuffs only for fruit and vegetable products permissible is and otherwise essentially packaging materials, machine parts, surfaces or Air are irradiated. The UV radiation sources are generally in a glass envelope contain and irradiate from close proximity, z. B. the o. G. Food and / or their preparation devices, or at a greater distance, z. As a ceiling fitting for air and surface sterilization, the effectiveness of UV radiation sources for the sterilization substantially from the unhindered access of the UV rays to the Disinfecting thing depends. The disadvantage is that in operation at the fraction of the glass envelope of a UV radiation source Broken glass can get into the food. safety devices against glass splinters prevent access of the UV rays to the disinfecting thing.
Aufgabe der Erfindung ist es, eine UV-Strahlenquelle zu schaffen, mit hoher Wirksamkeit und Betriebssicherheit und deren Verwendung anzugeben.task The invention is to provide a high UV radiation source Indicate efficacy and operational safety and their use.
Die Lösung erfolgt mit einer UV-Strahlenquelle mit den Merkmalen des Anspruchs 1 und der Verwendungen einer solchen UV-Strahlenquelle mit den Merkmalen des Anspruchs 8.The solution takes place with a UV radiation source with the features of the claim 1 and the uses of such a UV radiation source with the features of claim 8.
Gemäß der Erfindung ist eine UV-Strahlenquelle mit einer Folie mit erhöhter Durchlässigkeit für Strahlung mit Wellenlängen zwischen 240 und 270 nm beschrumpft. Die Folie enthält Fluorpolymere, wie z. B. auf Teflon basiertes Material oder sogenanntes MFA. Die Strahlenquelle ist für Augenschutz direkt beschrumpft. Die Folie lässt die aus der Strahlenquelle austretenden UV-Strahlen weitgehend ungehindert durch und hält gegebenenfalls Splitter einer geborstenen Strahlenquelle zurück. Bei vollständig durchgebrochener UV-Strahlenquelle zieht das Vakuum die Folie um die Bruchstelle(n) zusammen, so dass die UV-Strahlenquelle eine integrale Einheit bleibt. Erfindungsgemäß ist die UV-Strahlenquelle in Lüftungskanälen, von z. B. Klimaanlagen in Krankenhäusern, durch die Folie vor Auskühlung durch Anströmung und dem damit verbundenen Leistungsabfall der UV-Strahlenquelle geschützt. Die Folie ist hoch beständig gegen Säuren und Laugen und schützt die UV-Strahlenquelle vor Anlagerungen von Staub, Schmutz und Fingerschweiß.According to the invention is a UV source with a film with increased permeability for radiation with wavelengths shrunk between 240 and 270 nm. The film contains fluoropolymers, such as z. B. Teflon-based material or so-called MFA. The radiation source is for Eye protection shrunk directly. The foil leaves the from the radiation source Exiting UV rays largely unhindered by and stops if necessary Splinters of a burst radiation source back. When completely broken UV radiation source, the vacuum pulls the film around the break point (s) together so that the UV radiation source remains an integral unit. According to the invention UV radiation source in ventilation ducts, from z. B. Air conditioners in hospitals, through the film before cooling by flow and the associated power loss of the UV radiation source protected. The film is highly resistant to acids and lyes and protects the source of UV radiation from accumulation of dust, dirt and finger sweat.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung ist die UV-Strahlenquelle in einer Glashülle mit Quarzglas enthalten und die Folie mit erhöhter Durchlässigkeit für Strahlung mit Wellenlängen zwischen 240 und 270 nm ist um die Glashülle angeordnet. Die Glashülle enthält Quarzglas für verbesserte UV-Strahlendurchlässigkeit. Die Folie lässt die aus der Glashülle austretenden UV-Strahlen weitgehend ungehindert durch und hält gegebenenfalls Splitter einer geborstenen Glashülle zurück. Bei vollständig durchgebrochener UV-Strahlenquelle zieht das Vakuum in der Glashülle die Folie um die Bruchstelle(n) zusammen, so dass die UV-Strahlenquelle eine integrale Einheit bleibt.According to one advantageous embodiment of the invention is the UV radiation source in a glass envelope with Contain quartz glass and the film with increased permeability to radiation with wavelengths between 240 and 270 nm is around the glass envelope arranged. The glass envelope contains Quartz glass for improved UV ray transmission. The foil leaves the from the glass envelope Exiting UV rays largely unhindered by and stops if necessary Sliver of a broken glass shell back. When completely broken UV radiation source pulls the vacuum in the glass envelope Wrap the film around the breakage (s), leaving the UV source an integral unit remains.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Glashülle vorzugsweise mit der Einfassung von der Folie z. B. durch thermisches oder mechanisches Aufschrumpfen vollständig umgeben.According to one Another advantageous embodiment of the invention, the glass envelope is preferably with the border of the film z. B. by thermal or mechanical Shrink completely surround.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist Niederdruck in der Glashülle, so dass die Folie bei geborstener Glashülle nicht Druckbelastungen ausgesetzt ist. Alternativ zum Niederdruck kann eine Indium-Amalgam dotierte UV-Strahlquelle im Quarzglasrohr vorgesehen sein.According to one Another advantageous embodiment of the invention is low pressure in the glass envelope, so that the film with burst glass envelope does not pressure loads is exposed. As an alternative to low pressure, an indium amalgam can be used doped UV radiation source may be provided in the quartz glass tube.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Glashülle in einem metallischen oder Kunststoffgehäuse mit mindestens einem Strahlungsfenster für gerichtete Strahlung gehalten.According to one Another advantageous embodiment of the invention, the glass envelope is in one metallic or plastic housing held with at least one radiation window for directed radiation.
Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist die Folie eng anliegend aussen um die Glashülle oder aussen um das metallische oder Kunststoffgehäuse.According to one Another advantageous embodiment of the invention is the film close fitting outside around the glass envelope or outside around the metallic one or plastic housing.
Gemäß der Erfindung ist die Verwendung mindestens einer UV-Strahlenquelle mit der erfindungsgemäßen Gehäuse- oder Folienkonstruktion zum Entkeimen in der Lebensmittelbranche oder in Lüftungsanlagen vorgesehen. Die UV-Strahlenquelle mit der erfindungsgemäßen Gehäuse- oder Folienkonstruktion gewährleistet durch dekontaminierte Packstoffe durch UV-C-Strahlung geringere Produktionsausfälle an Anlagen zur Entkeimung von Lebensmitteln, in der Medizin oder Industrie.According to the invention is the use of at least one UV radiation source with the housing or housing according to the invention Foil construction for sterilization in the food industry or in ventilation systems intended. The UV radiation source with the housing or housing according to the invention Foil construction guaranteed Decontaminated packaging materials reduce production losses due to UV-C radiation for the disinfection of food, in medicine or industry.
