Description

VERFAHREN UND EINRICHTUNG ZUR OZONERZEUGUNG AUSPROCESS AND EQUIPMENT FOR OZONE PRODUCTION

KOHLENDIOXID (CO2) Verfahren und Einrichtung zur Ozonerzeugung aus Kohlendioxid (CO2) Die Erfindung betrifft eine Methode der Ozonerzeugung aus Kohlendioxid bei der im Endprodukt neben dem für die Sterilisation notwendigen Ozon keine für die Anwendung störenden Fremdgase wie etwa Sauerstoff (°2)' Stickstoff (N2) und Stickstoffverbindungen (NO...x) anfallen.CARBON DIOXIDE (CO2) Process and device for ozone generation from carbon dioxide (CO2) The invention relates to a method of ozone generation from Carbon dioxide in the end product in addition to the ozone required for sterilization no foreign gases such as oxygen (° 2) 'nitrogen that interfere with the application (N2) and nitrogen compounds (NO ... x) occur.

Die vorbeschriebene neue Methode der Ozonerzeugung zeichnet sich nicht etwa durch eine besonders hohe Ozonausbeute aus, sondern bietet die Möglichkeit ein Ozon zu erzeugen, das frei von störenden Sauerstoff-und ggf. auch Stickstoffmolekülen ist.The new method of ozone generation described above does not stand out for example through a particularly high ozone yield, but offers the possibility to generate an ozone that is free of disruptive oxygen and possibly also nitrogen molecules is.

Stand der Technik: Es ist bekannt, das im elektrischen Feld des Ozonisators, in dem Raum also, in dem die sogenannte schwache Glimmentladung auftritt, (Koronabildung) bedingt durch den Elektronenbeschuß, in mit Aromaten beladener Luft elektrochemische Umwandlungsprozesse stattfinden; siehe hierzu Offenlegungsschrift 24 59 460 "elektrochemische Luftbehandlungseinrichtung".State of the art: It is known that in the electric field of the ozonizer, in the room in which the so-called weak glow discharge occurs (corona formation) due to the electron bombardment, electrochemical in air laden with aromatics Transformation processes take place; see laid-open specification 24 59 460 "electrochemical" Air treatment device ".

Es ist aber Aufgabe dieser Erfindung ein Ozon zu erzeugen, daß ohne den Einfluß von störenden Fremdgasen eingesetzt werden kann.But it is the object of this invention to generate an ozone that without the influence of interfering foreign gases can be used.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Ozonisator handelsüblicher Bauart statt mit trockener Luft oder Sauerstoff mit Kohlendioxid beschickt wird, einem Gas also in dem der Sauerstoff Molekular eingebunden ist.According to the invention, this object is achieved in that the ozonizer commercial design instead of dry air or oxygen with carbon dioxide is charged, a gas in which the oxygen is molecularly integrated.

Ein Versuch mit Kohlendioxid hat folgendes Ergebnis erbracht: - Einsatzgas C02 - Gasdurchsatz 100 1 C02/h - Ozonproduktion 1,44 g 03/h - Ozonkonzentration 670 VOL ppm Vergleichsweise zu der Ozonproduktion bei den Einsatzgasen Luft und Sauerstoff ist die Ozonausbeute hier relativ gering.A test with carbon dioxide produced the following results: - feed gas C02 - gas throughput 100 1 C02 / h - ozone production 1.44 g 03 / h - ozone concentration 670 VOL ppm Compared to the ozone production with the feed gases air and Oxygen, the ozone yield is relatively low here.

Aber gerade dieses Gas eignet sich wegen seiner sterilisierenden Wirkung einerseits und demneutralen Verhalten des Kohlendioxid andererseits hervorragend um in Tüten und Plastikbehältern verpackte Lebensmittel aller Art, Kräuter und medizinische Instrumente z. B. Einwegspritzen u.s.w. über längere Zeit steril zu halten.But precisely this gas is suitable because of its sterilizing effect on the one hand and the neutral behavior of the carbon dioxide on the other to all kinds of food, herbs and medicinal products packed in bags and plastic containers Instruments e.g. B. disposable syringes etc. keep sterile for a long time.

Letzteres ist zwar auch bei getrennter Zugabe von ozonhaltiger Luft bzw. ozonhaltigem Sauerstoff und Kohlendioxid möglich. Jedoch wird die Haltbarkeit der Lebensmittel dadurch reduziert, weil eben die ozonisierte Luft bzw. der ozonisierte Sauerstoff große Anteile von Sauerstoff beinhalten, der seinerseits die Lebensfähigkeit von Mikroben fördert.The latter is true even with separate addition of ozone-containing air or ozone-containing oxygen and carbon dioxide possible. However, the durability will the food is reduced because of the ozonated air or the ozonated air Oxygen contain large amounts of oxygen, which in turn increases viability of microbes promotes.

Zur Information sei darauf hingewiesen: Luft kann nur bis max.2,5Vol.% ozonisiert werden, Sauerstoff bis max. 10 Vol. %.For information, please note: Air can only be used up to a maximum of 2.5% by volume. are ozonated, oxygen up to max. 10 vol.%.

Ein weiterer Vorteil dieses Verfahren ist, daß C02 trocken ist, es ist frei von Feuchtigkeit und benötigt daher keinen Gastrockner.Another benefit of this process is that C02 is dry there is free from moisture and therefore does not require a gas dryer.

Letzteres ist bei kleinen Ozonerzeugern ein erheblicher Kostenfaktor.The latter is a significant cost factor for small ozone generators.

Die erzielbaren Vorteile dieser Erfindung bestehen insbesondere darin, daß bei geringstem Installationswert der Ozonanlage, ein ozonhaltiges Gas erzeugt wird, das je nach dem Einsatzfall frei ist von störenden Fremdgasen. Letzteres trifft besonders für die sterile Verpackung von Lebensmittel, Kräutern und medizinischen Instrumenten zu.The achievable advantages of this invention consist in particular in that with the lowest installation value of the ozone system, an ozone-containing gas is generated which, depending on the application, is free of interfering foreign gases. The latter meets especially for the sterile packaging of food, herbs and medicinal products Instruments too.
