It can be used without any technical modifications existing UV lamps in water and wastewater treatment plants be replaced.
In der Umweltschutztechnik werden häufig Flüssigkeiten und Gase durch UV-Bestrahlung behandelt.Liquids and gases are often used in environmental protection technology Treated with UV radiation.
Es ist im Stand der Technik bekannt, zum Reinigen und Entkeimen von Flüssigkeiten und Gasen UV-Strahler einzusetzen. Bei den bekannten Vorrichtungen werden im allgemeinen hierfür stabförmige UV-Strahler eingesetzt, bei denen die elektrische Energie über an den Stirnflächen angebrachte Elektroden im Inneren des Ladungsraumes eingespeist wird.It is known in the prior art for cleaning and sterilizing Use liquids and gases with UV lamps. With the known Devices are generally rod-shaped UV lamps for this used where the electrical energy is on the end faces attached electrodes is fed inside the cargo space.
Dabei ist nachteilig, daß die für die Einspeisung maximal mögliche Leistung durch die Elektroden und Geometrie des Entladungsraumes begrenzt wird. Die Lebensdauer eines derartigen Strahlers wird durch die verwendeten Elektroden auf maximal zehntausend Stunden begrenzt. Ferner ist nachteilig, daß chemische Reaktionen der in den Entladungsräu men vorhandenen Gase mit dem Elektrodenmaterial durch entsprechende Werkstoffwahl ausgeschlossen werden müssen. Dadurch können nur bestimmte Gase und Gasgemische für die Entladung zur Strahlungserzeu gung verwendet werden. Die Erzeugung von Spektren mit beliebiger Zusammensetzung und Wellenlängenverteilung wird dann stark einge schränkt.It is disadvantageous that the maximum possible for the feed Power through the electrodes and geometry of the discharge space is limited. The lifespan of such a radiator is determined by used electrodes limited to a maximum of ten thousand hours. A further disadvantage is that chemical reactions in the discharge space existing gases with the electrode material by appropriate Choice of materials must be excluded. This can only certain gases and gas mixtures for the discharge to generate radiation be used. The generation of spectra with any The composition and wavelength distribution is then strongly incorporated limits.
Im Stand der Technik ist es auch bekannt, für die Strahlungserzeugung elektrodenlose Strahler zu verwenden. Bei diesen Strahlern wird ein hochfrequentes elektromagnetisches Feld eingekoppelt. Die Einkopplung erfolgt bei den bekannten Anordnungen auf induktiven Wege mit Hilfe einer Ferrittspule oder durch Mikrowellen.It is also known in the prior art for the generation of radiation to use electrodeless spotlights. With these spotlights is a high-frequency electromagnetic field coupled. The coupling takes place in the known arrangements by inductive means a ferrite coil or by microwaves.
Bei den bekannten elektrodenlosen Strahlern ist nachteilig, daß vorhandene Wasser- und Abwasseraufbereitungssysteme, die mit stabförmigen Strah lern ausgerüstet sind, nicht mit elektrodenlos angeregten Strahlern nachge rüstet werden können.In the known electrodeless radiators it is disadvantageous that existing ones Water and wastewater treatment systems using rod-shaped jets learners are not equipped with electrodelessly excited emitters can be equipped.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die es gestattet, vorhandene Systeme der Wasser- und Abwasserbehandlung ohne konstruktive Änderungen durch UV-Strah ler mit elektrodenloser Anregung austauschen zu können. The invention has for its object a device of the beginning specified type, which allows existing systems of water and wastewater treatment without structural changes due to UV rays to be able to exchange with electrodeless excitation.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der Quarzglaskör per aus einem langgestreckten Doppelmantelgefäß besteht, das in Form eines U-förmigen Ringes ausgebildet ist, wobei sich in dem von dem Doppelmantelgefäß umschlossenen Raum ein Trägerelement aus strah lungsbeständigem Material befindet, auf dem ein Teilelement eines HF-Schwingkreises angeordnet ist.According to the invention the object is achieved in that the quartz glass body per consists of an elongated double jacket vessel that is in shape a U-shaped ring is formed, in which of the Double-walled vessel enclosed space a beam element from beam resilient material is on which a sub-element of a HF resonant circuit is arranged.
