Des weiteren betrifft die vorliegende Erfindung die Verwendung dieser Filtereinheit zur Reinigung von Luft, insbesondere zur Herstellung hochreiner Luft, bzw. zur Entfernung von Gas-, Geruchs- oder Giftstoffen aus Luftströmen, beispielsweise in (Be-)Lüftungsanlagen, Ventilationssystemen, Klimaanlagen oder dergleichen.Furthermore, the present concerns Invention the use of this filter unit for cleaning Air, especially for the production of high-purity air or for removal of gas, odor or toxins from air flows, for example in (ventilation) systems, Ventilation systems, air conditioning systems or the like.
Schließlich betrifft die vorliegende Erfindung Anlagen bzw. Systeme zur Luftreinigung bzw. Bereitstellung oder Aufbereitung von Luft, insbesondere (Be-)Lüftungsanlagen, Ventilationssysteme oder Klimaanlagen, mit dieser Filtereinheit.Finally, the present concerns Invention systems or systems for air purification or provision or treatment of air, in particular (ventilation) systems, ventilation systems or air conditioners, with this filter unit.
Durch steigendes Umweltbewußtsein sowie durch hochempfindliche Analysemethoden ist die Belastung der Umwelt durch Schadstoffe immer mehr ins Licht der Öffentlichkeit gerückt.Through increasing environmental awareness as well as through highly sensitive analysis methods is the pollution of the environment Pollutants increasingly in the public eye.
Die zunehmende Industrialisierung hat zudem zu einer weiträumigen Verschmutzung der Atmosphäre geführt. Jede Art von Verbrennungsvorgang, z. B. in Kraftwerken, von Automobilmotoren, durch Heizen etc., führt zu unerwünschten Verbrennungsprodukten, insbesondere oxidierten Kohlenstoffverbindungen, Stickoxiden, unvollständig verbrannten Kohlenwasserstoffen und dergleichen.The increasing industrialization also has a spacious Pollution of the atmosphere guided. Any type of combustion process, e.g. B. in power plants, by automotive engines Heating etc., leads to undesirable Combustion products, especially oxidized carbon compounds, Nitrogen oxides, incomplete burned hydrocarbons and the like.
Daneben gibt es Schadstoffbelastungen durch kontaminierte Räume, in denen schadstoffbelastete Materialien verbaut sind (z. B. PCB-belastete Baustoffe etc.). Auch von Möbelstücken, Wandanstrichen, Teppichbodenklebern und dergleichen können Giftstoffe freigesetzt werden.There are also pollutants contaminated rooms, in which contaminated materials are installed (e.g. PCB-contaminated building materials Etc.). Also of furniture, wall paintings, Carpet adhesives and the like can release toxins become.
In jüngster Zeit hat zudem die Gefahr zugenommen, daß durch terroristische Anschläge gezielt Giftstoffe in Klimaanlagen von Gebäuden, in die Belüftungssysteme von U-Bahnschächten etc. eingetragen werden.Recently there has also been a danger increased that by terrorist attacks targeted toxins in air conditioning systems of buildings, in the ventilation systems of subway shafts etc. are entered.
Daher besteht insgesamt ein großer Bedarf, verschiedenartigste luftverschmutzende Substanzen, insbesondere schädigende bzw. störende Schad-, Gift- oder Geruchsstoffe, aus der Luft zu entfernen. Hierzu gibt es im Stand der Technik eine Reihe von Verfahren, um solche Substanzen zu entfernen. Beispielsweise seien hier mechanische Filterungsverfahren, Umsetzung bzw. Zersetzung der störenden bzw. schädigenden Substanzen sowie Absorptions- und Adsorptionsverfahren genannt.Therefore, there is a great need in general, the most varied air polluting substances, in particular damaging or disturbing harmful, Remove toxic or odorous substances from the air. There are There are a number of methods in the prior art for such substances to remove. For example, here are mechanical filtering methods, Implementation or decomposition of the disruptive or damaging Substances and absorption and adsorption processes called.
Bei den Adsorptionsverfahren kommen adsorptiv wirkende Filtereinheiten zum Einsatz. Das Problem hierbei ist oftmals, daß die aus dem Stand der Technik bekannten Filtereinheiten eine nicht immer ausreichende Adsorptionskapazität aufweisen, die relativ schnell erschöpft ist, so daß die Filtermaterialien ausgetauscht werden müssen. Des weiteren besitzen aus dem Stand der Technik bekannte Adsorptionsfiltereinheiten eine nicht immer ausreichende "Spontaneität" bzw. Adsorptionskinetik, so daß es zu Durchbrüchen kommen kann. Oftmals bieten die aus dem Stand der Technik bekannten Adsorptionsfiltereinheiten auch eine nur unzulängliche Adsorptionsleistung und sind nicht universell für die Adsorption unterschiedlichster Schad- bzw. Giftsstoffe geeignet.Come in the adsorption process adsorptive filter units are used. The problem here is often that the filter units known from the prior art are not always one sufficient adsorption capacity have, which is exhausted relatively quickly, so that the filter materials need to be replaced. Furthermore, have adsorption filter units known from the prior art a not always sufficient "spontaneity" or adsorption kinetics, so it's too breakthroughs can come. Often, those known from the prior art offer Adsorption filter units also an inadequate adsorption performance and are not universal for the adsorption of various pollutants or toxic substances suitable.
