Abstract
Description
Reaktor zur Geruchs- und Keimminderung mittels UV-Katalysator-Technologie wird in Betrieben, in denen vorgebrauchte, recycelbare Wertstoffe angeliefert, zwischengelagert bzw. sortiert sowie an Produktionsstätten, in denen Gase organischer Zusammensetzung emittiert werden, eingesetzt. Desweiteren wird der Reaktor in Betrieben/Lebensmittelindustrie eingesetzt, die keimfreie Zuluft als Produktionsluft benötigen. Bei Recyclingbetrieben oder Betrieben in denen Geruchsstoffe organischer Zusammensetzung emittiert werden, wird der Reaktor zur Umluft- und/oder Abluftreinigung der organischen und anorganischen Geruchsstoffe sowie zur Abtötung der Viren, Pilze und Mikroorganismen verwendet.Reactor for odor and germ reduction using UV catalyst technology is delivered to companies where pre-used, recyclable materials are delivered, temporarily stored or sorted as well as at production sites in which gases organic composition are used. Furthermore, the Reactor used in companies / food industry, the aseptic supply air as Need production air. At recycling companies or companies in which Odor substances of organic composition are emitted, the reactor for air and / or exhaust air purification of organic and inorganic Odorants as well as to kill viruses, fungi and microorganisms used.
In der Massentierhaltung kann der Reaktor ebenfalls zur Abluftreinigung sowie zur Bekämpfung der in der Tierhaltung vorkommenden Mikroorganismen eingesetzt werden.In factory farming, the reactor can also be used for exhaust air purification and Combating the microorganisms occurring in animal husbandry become.
Das bedeutet, daß der Reaktor sowohl für die Zuluftaufbereitung, um keimfreie sowie geruchsneutrale Luft zu erzeugen, als auch zur Abluftreinigung, um Gase organischer und/oder anorganischer Zusammensetzung sowie mikrobiell belastete Abluft zu behandeln, großtechnisch eingesetzt werden kann.This means that the reactor for both the supply air treatment to aseptic as well as generating odorless air, as well as for exhaust air purification to gases organic and / or inorganic composition as well as microbially contaminated Treat exhaust air, can be used on an industrial scale.
Die zu reinigende Luft wird mittels eines Saugzugventilators angesaugt und dem UV-Reaktor zugeführt. In dem Reaktor befinden sich UV-Strahlenquellen spezieller Wellenlänge sowie ein Katalysator, der im Reaktorinnenraum angebracht ist. Der Prozeß der Geruchsminderung richtet sich nach der Reaktorgröße bzw. Verweilzeit des Gases in dem Reaktor, der Anzahl der UV-Strahlenquellen, der Reaktionsfläche an dem der Katalysator angebracht ist sowie der organischen Zusammensetzung des geruchsintensiven, keimbelasteten Gases.The air to be cleaned is sucked in by a suction fan and the UV reactor supplied. There are UV radiation sources in the reactor special wavelength as well as a catalyst in the interior of the reactor is appropriate. The process of odor reduction depends on the Reactor size or residence time of the gas in the reactor, the number of UV radiation sources, the reaction surface to which the catalyst is attached and the organic composition of the odor-intensive, germ-laden gas.
Um eine intensive Wechselwirkung zwischen den Geruchskomponenten, der UV Strahlung sowie dem Katalysator (Titandioxid, anatase Modifikation) zu erzielen, ist eine angemessene Verweilzeit notwendig, die durch Umlenk- und/oder Lochbleche erzielt wird.To an intensive interaction between the odor components, the UV To achieve radiation and the catalyst (titanium dioxide, anatase modification), a reasonable dwell time is necessary, which is due to deflection and / or Perforated sheets is achieved.
Folgende grundlegende Reaktionen treten in dem Reaktionsraum auf: The following basic reactions occur in the reaction space:
Wasser (feuchte Luft) bildet unter UV-Einwirkung in Verbindung mit Titandioxid Hydroxylradikale.Water (moist air) forms under the influence of UV in conjunction with Titanium dioxide hydroxyl radicals.
Hydroxylradikale besitzen ein großes Oxidationspotential und oxidieren die meisten Geruchsstoffe auf.Hydroxyl radicals have a large oxidation potential and oxidize them most odorants.
Einige C-H-Verbindungen bilden unter UV-Einwirkung Radikale, die wiederum mit dem Sauerstoff aus der Luft weiter reagieren und somit die Geruchs komponente zerstört wird.Some C-H compounds form radicals under the action of UV, which in turn continue to react with the oxygen from the air and thus the smell component is destroyed.
Der Vorteil liegt darin, daß der durch das UV-Licht aktivierte Katalysator (Titandioxid TiO2) mit dem Wasser aus der Luft Hydroxylradikale bildet, die auf die Geruchskomponenten (organische Zusammensetzung) oxidierend wirken. Dadurch entstehen geruchsneutrale Komponenten.The advantage is that the catalyst activated by the UV light (titanium dioxide TiO 2 ) forms with the water from the air hydroxyl radicals, which have an oxidizing effect on the odor components (organic composition). This creates odorless components.
Die Mikroorganismen werden unter Einwirkung von UV-Licht abgetötet bzw. inaktiviert. Die Strahlung der UV-Röhren liegt im Wellenlängenbereich zwischen 172-280 nm und entspricht der Absorptionswellenlänge der Desoxyribo nucleinsäure, dem Baustein, der die genetische Erbinformation der Mikroorganismenzelle beinhaltet. Durch die Absorption energiereichen Lichtes werden die DNS-Moleküle in einen angeregten Zustand versetzt, wobei die aufgenommene Energie ausreicht, die Zelle so stark zu schädigen, daß sie abstirbt bzw. inaktiviert wird.The microorganisms are killed under the action of UV light or deactivated. The radiation from the UV tubes lies in the wavelength range between 172-280 nm and corresponds to the absorption wavelength of the deoxyribo nucleic acid, the building block that the genetic information of the Microorganism cell contains. High energy through absorption In light, the DNA molecules are put into an excited state, whereby the absorbed energy is sufficient to damage the cell so much that it dies or is inactivated.
Nachdem die Luft durch den Reaktor geführt wurde ist sie soweit von Geruchsemittienten und Mikroorganismen befreit, daß sie ohne weitere Nachbehandlung in die Atmosphäre abgeleitet werden kann.After the air has been led through the reactor, it is as far from Odor emitters and microorganisms exempted them without further Aftertreatment can be derived into the atmosphere.
Um den Reaktorinnenraum vor Staubpartikeln und Aerosolen zu schützen, ist am Reaktoreingang ein Partikel- bzw. Aerosolfilter plaziert. Da Staubablagerungen auf den UV-Strahlenquellen bzw. dem Katalysator die Leistung mindern. In order to protect the reactor interior from dust particles and aerosols, is on Placed a particle or aerosol filter. Because dust deposits on reduce the power of the UV radiation sources or the catalytic converter.
Der Vorteil dieser UV-Technologie liegt im geringen Druckverlust des Reaktors, die Katalysator unterstützte Oxidation der Geruchskomponenten, dem apparativ gleich aufgebauten und kostengünstigen Reaktor sowie im niedrigen Energieverbrauch der eingesetzten UV-Strahlenquellen.The advantage of this UV technology is the low pressure drop in the reactor, the catalyst supported oxidation of the odor components, the apparatus identically constructed and inexpensive reactor as well as in the low Energy consumption of the UV radiation sources used.
Desweiteren entstehen keine Reststoffe, die zu entsorgen wären.Furthermore, there are no residues to be disposed of.
