Ozonvernichter-Einheit (Scrubber) für OzonanaiysatorenOzone destroyer unit (scrubber) for ozone analyzers
Es werden z.Z. hauptsächlich zwei Typen von Ozon-Scrubbern im Referenzzweig von Ozon-Analysatoren für den Einsatz vorzugsweise im Immissionsbereich oder für MAK-Überwachungen eingesetzt:There are currently two main types of ozone scrubbers in the reference branch of ozone analyzers for use primarily in the emission range or for MAK monitoring:
a) Kufpemetze mit Manganoxidbeschichtunga) Copper mesh with manganese oxide coating
b) Siberwolle, beheiztb) Silver wool, heated
Scrubber a) gibt es z.B. in der Ausführung mit mehreren (z.B. 12 Stück) übereinanderliegenden Netzen. Zur gleichmäßigen Durchströmung befindet sich an der Lufteintrittsseite oftmals eine Fritte. Scrubber b) benötigen eine Heizung.Scrubbers a) are available, for example, in a design with several (e.g. 12) nets on top of each other. To ensure even air flow, there is often a frit on the air inlet side. Scrubbers b) require a heater.
Die bekannten Ozon-Scrubber weisen insbesondere folgende Nachteile bzw. Unzulänglichkeiten auf:The known ozone scrubbers have the following disadvantages or shortcomings in particular:
a) Rest-Querempfindlichkeiten gegenüber Begleitgasen, &zgr;. &Bgr;. Kohlenwasserstoffen (bes. Aromaten) und Feuchte.a) Residual cross-sensitivities to accompanying gases, z. B. hydrocarbons (especially aromatics) and moisture.
b) Temperaturunterschiede der durchströmenden Gase (z.B. beim Umschalten auf Nulluft) wirken sich negativ aus.b) Temperature differences of the gases flowing through (e.g. when switching to zero air) have a negative effect.
c) Eine exakte Nullpunktfestlegung bereitet oftmals Probleme.c) Determining the exact zero point often causes problems.
d) Belastete Meßluft (Schadstoffe, Nebel) verkürzt die Standzeit erheblich.d) Contaminated measuring air (pollutants, fog) significantly shortens the service life.
e) ReI. hohe Fertigungskosten und Betriebskosten.e) ReI. high manufacturing costs and operating costs.
f) Hoher Aufwand zur Einhaltung gleichbleibender Qualität, besonders bei unterschiedlichen Fertigungs-Chargen (es ist z.B. weltweit nur ein Hersteller von Manganoxid überzogenen Kupfernetzen bekannt, der das erforderliche Know-how besitzt).f) High effort to maintain consistent quality, especially with different production batches (for example, there is only one manufacturer of manganese oxide-coated copper mesh worldwide that has the necessary know-how).
Eine starke Verminderung bzw. eine Vermeidung der oben aufgeführten Nachteile ergibt sich durch den Einsatz der neuen ®noXon-S Scrubber. Eine deutliche Rest-Querempfindlichkeit gegenüber Kohlenwasserstoffen bei Tests mit den neuen Scrubbem ist noch nicht beobachtet worden. Temperaturunterschiede und belastete Meßluft haben keinen beobachteten Einfluß. Eine gleichbleibend hohe Qualität (vergl. f) oben) ist immer gewährleistet.A significant reduction or avoidance of the disadvantages listed above is achieved by using the new ®noXon-S scrubbers. A significant residual cross-sensitivity to hydrocarbons in tests with the new scrubbers has not yet been observed. Temperature differences and contaminated measuring air have no observed influence. A consistently high quality (see f) above) is always guaranteed.
Außerdem erfordern die ®noXon-S Scrubber einen weit geringeren Fertigungsaufwand und haben deutlich niedrigere Betriebskosten.In addition, the ®noXon-S scrubbers require far less manufacturing effort and have significantly lower operating costs.
Bei der Konzeption sind folgende Punkte besonders berücksichtigt worden, die Voraussetzung für die Funktionstüchtigkeit sind:The following points were given special consideration during the design process, which are a prerequisite for functionality:
a) Optimierung der mit dem Gasstrom in Berührung kommenden Oberfläche,a) Optimization of the surface in contact with the gas flow,

d) Wahl eines geeigneten Gehäusematerialsd) Choice of a suitable housing material
e) Generation von Kalibrier-Nulluft (Ozon-freie Luft) mit Hilfe einer ®noXon Patrone anstelle der Aktivkohlepatronee) Generation of calibration zero air (ozone-free air) using a ®noXon cartridge instead of the activated carbon cartridge
Die exakte Nullpunktfindung ist oftmals ein Problem. Bisherige Handhabung: Finding the exact zero point is often a problem. Previous handling:
Die meisten Ozonanalysatoren für den Immissionsbereich haben eine Option zur internen Nulluftbereitstellung. Die Nulluft für Ozon wird mit Hilfe einer Aktivkohlepatrone, die sich im Analysator oder außen an ihm befindet, aus der Umgebungsluft erzeugt. Diese wird über ein Zwei- oder Mehrwegeventil in wählbaren Zeitintervallen aufgeschaltet.Most ozone analyzers for the immission area have an option for internal zero air provision. The zero air for ozone is generated from the ambient air using an activated carbon cartridge, which is located in the analyzer or on the outside of it. This is switched on at selectable time intervals via a two-way or multi-way valve.
Da die Aktivkohle die meisten Begleitgase ganz oder teilweise (abhängig auch vom Alter der Aktivkohle) absorbiert, ist "die Null" nicht genau definiert.Since the activated carbon absorbs most of the associated gases either completely or partially (depending on the age of the activated carbon), "zero" is not precisely defined.
Außerdem ergibt sich die Schwierigkeit, daß oft ein "Feuchtegleichgewicht" des Scrubbers im Analysator mit der Nulluft in kürzester Zeit vorliegen muß, z.B. in deutlich weniger als 10 Minuten. Das Verschwinden des "letzten Tailings" von z.B. 2 bis 3ppb (Wasserdampf-Querempfindlichkeit) erfordert eine längere Zeit.Another difficulty is that a "humidity equilibrium" of the scrubber in the analyzer with the zero air must often be achieved in a very short time, e.g. in significantly less than 10 minutes. The disappearance of the "last tailing" of e.g. 2 to 3 ppb (water vapor cross-sensitivity) requires a longer time.
Nulluftdefinition mit ®noXon-S:Zero air definition with ®noXon-S:
Eine ideale "Nulluft" für Ozonmessungen ist ein Gasstrom, aus dem Ozon quantitativ
entfernt wurde und die übrigen "Begleitgaskomponenten" unverändert bleiben.
Es besteht jetzt erstmalig die Möglichkeit, eine solche Nulluft annähernd mit Hilfe
von ®noXon-S Nulluftpatronen zu erzeugen. Beim Durchströmen einer solchen Patrone, die prinzipiell wie die Scrubber aufgebaut sind, wird schon nach sehr
kurzer Zeit (kurzer spontaner Response) bezüglich der Begleitkomponenten ein Fließgleichgewicht erreicht. Eine Ausnahme bildet nur NO2, das zum Teil absorbiert
wird, aber keine Querempfindlichkeit im Analysator verursacht.An ideal "zero air" for ozone measurements is a gas stream from which ozone has been quantitatively removed and the other "associated gas components" remain unchanged.
For the first time, it is now possible to generate such zero air using ®noXon-S zero air cartridges. When flowing through such a cartridge, which is basically constructed like the scrubber, a flow equilibrium is reached with regard to the accompanying components after a very short time (short spontaneous response). The only exception is NO 2 , which is partially absorbed but does not cause any cross-sensitivity in the analyzer.
Besonders vorteilhaft ist die Kombination Nulluftfilter mit Scrubber desselben Füllmaterials, nämlich ®noXon-S.The combination of zero air filter with scrubber made of the same filling material, namely ®noXon-S, is particularly advantageous.
