Description
Die Erfindung bezieht sich auf eine Luftreinigungsanlage mit wenigstens einem Filter zur Partikelabtrennung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a Air purification system with at least one filter for particle separation according to the generic term of claim 1.
Um die Luft zu reinigen, die z.B. im Personeninnenraum eines Kraftfahrzeuges zugeführt wird, werden Filter verwendet, die feinste Partikel, wie Pollen, zurückhalten. Zudem werden Luftreinigungsanlagen häufig mit einem beispielsweise mit Aktivkohle gefüllten Adsorber ausgestattet, durch den störende Gerüche, aber auch toxische Gase, insbesondere karzenogene Stoffe, wie aromatische Kohlenwasserstoffe, aus der Luft entfernt werden, die in den Personeninnenraum strömt.To clean the air, e.g. is supplied in the passenger compartment of a motor vehicle, filters are used to hold back the finest particles, such as pollen. In addition, air purification systems often equipped with an adsorbent filled with activated charcoal, for example, by the annoying odors, but also toxic gases, especially carcenogenic substances, such as aromatic Hydrocarbons, which are removed from the air, in the passenger compartment flows.
Bei Luftreinigungsanlagen, bei denen ein Partikelfilter einem solchen Adsorber vorgeschaltet ist, ist jedoch eine überraschend starke Zunahme des Luftströmungswiderstandes bzw. eine entsprechende Herabsetzung des Luftdurchsatzes durch die Luftreinigungsanlage festgestellt worden, ferner eine verhältnismäßig rasche Abnahme der Adorptionsfähigkeit des Adsorbers. Dabei ist zu berücksichtigen, dass das Gebläse bei einer solchen Anlage derart ausgelegt ist, dass der Luftdurchsatz bei Normalbetrieb bei etwa 300 kg Luft pro Stunde liegt.In air purification systems in which a particle filter is connected upstream of such an adsorber is but a surprise strong increase in airflow resistance or a corresponding reduction of the air flow through the Air purification system has been found, also a relatively fast Decrease in the adsorption capacity of the adsorber. It should be noted that the blower is designed in such a system such that the air flow in normal operation is about 300 kg of air per hour.
Aus der
Aufgabe der Erfindung ist es, die Standzeit einer Luftreinigungsanlage mit einem Filterwesentlich zu verlängern. The object of the invention is that Service life of an air purification system with a filter essential to extend.
Dies wird erfindungsgemäß durch die Merkmale des Anspruchs 1 erreicht, wobei die Luftreinigungsanlage zur Beseitigung von Schadstoffen einen Filter in Form einer. rotierenden Scheibe und eine Heizeinrichtung in Form eines Mikrowellengenerators zum Beheizen und Sterilisieren des Filters aufweist. Der Filter ist einem Adsorber oder einer Klimaanlage vorgeschaltet.This is inventively achieved the features of claim 1, wherein the air purification system to eliminate pollutants a filter in the form of a. rotating Disk and a heater in the form of a microwave generator for heating and sterilizing the filter. The filter is upstream of an adsorber or an air conditioner.
Wie festgestellt werden konnte, ist die Zunahme des Luftströmungswiderstandes hauptsächlich darauf zurückzuführen, dass auf dem Filter mit der Zeit sessile Mikroorganismen aufwachsen, die zu einer Verengung bzw. Verstopfung der Filterporen führen. Da insbesondere ein feuchtes, warmes Klima das Wachstum der Mikroorganismen beschleunigt, treten die geschilderten Probleme, insbesondere bei Fahrzeugen auf, die in den Tropen eingesetzt werden.As could be stated, is the increase in airflow resistance mainly due to that growing on the filter with time sessile microorganisms, which lead to a narrowing or blockage of the filter pores. There especially a humid, warm climate the growth of microorganisms accelerated, the problems described, especially in vehicles that are used in the tropics.
Die auf dem Filter aufgewachsenen Mikroorganismen können zudem geruchsintensive Stoffwechselprodukte abgeben, die in den Personeninnenraum gelangen können.The grown on the filter Microorganisms can In addition, release odorous metabolic products that in the Person interior can get.
Ferner können die Mikroorganismen durch den Filter hindurchwachsen. Sie führen damit zu einer Korrosion der Klimaanlage und anderer Teile der Luftreinigungsanlage. Ferner zerstören sie die aktiven Absorptionsstellen des Adsorbers, wenn sie in den Adsorber gelangen.Furthermore, the microorganisms by the Filter grow through. They lead thus to a corrosion of the air conditioner and other parts of the air purification system. Further destroy they the active absorption sites of the adsorber when they enter the Adsorber arrive.
Durch das Wachstum insbesondere pathogener Mikroorganismen auf dem Filter kann zudem die Gesundheit der Kraftfahrzeuginsassen gefährdet werden.By the growth in particular pathogenic Microorganisms on the filter can also improve the health of the vehicle occupants be endangered.
Die Sterilisation der Mikroorganismen dürfte bei der erfindungsgemäßen Anlage einmal dadurch erfolgen, dass die Mikroorganismen durch die Temperaturerhöhung abgetötet werden, die durch die Absorption der Mikrowellen in den Mikroorganismen bzw., wenn der Filter aus einem Mikrowellen absorbierenden Material besteht, durch die Absorption der Mikrowelle an dem Filter auftritt. Zum anderen wird durch die Absorption der Mikrowellen die DNS der Mikroorganismen zerstört. Dadurch dürften vor allem weniger wasserhaltige Mikroorganismen, wie Viren und Pilze abgetötet werden.Sterilization of microorganisms should be included the plant of the invention once done by killing the microorganisms by increasing the temperature, due to the absorption of microwaves in the microorganisms or if the filter consists of a microwave absorbing material, due to the absorption of the microwave on the filter. To the Others, by the absorption of microwaves, become the DNA of microorganisms destroyed. This is likely especially less water-containing microorganisms, such as viruses and fungi killed become.
Zur Sterilisation müssen die Mikroorganismen einer Temperatur von wenigstens 120°C, vorzugsweise wenigstens 160°C mindestens 10 Minuten, vorzugsweise mindestens 30 Minuten ausgesetzt werden.For sterilization must Microorganisms at a temperature of at least 120 ° C, preferably at least 160 ° C exposed for at least 10 minutes, preferably at least 30 minutes become.
Die Filter können Tiefenfilter, also Filter größerer Schichtdicke sein, die Luftdurchgangskanäle besitzen, oder Planfilter.The filters can be depth filters, so filters larger layer thickness be that have air passageways, or plan filter.
Falls Tiefenfilter verwendet werden, kann das Filtermaterial mikrowellentransparent sein, so dass die Mikrowelle von den Mikroorganismen selbst absorbiert wird. Falls Planfilter zum Einsatz kommen, kann das Filtermaterial auch mikrowellenabsorbierend sein.If depth filters are used, the filter material can be microwave transparent, so that the Microwave is absorbed by the microorganisms themselves. If Plan filter can be used, the filter material and microwave-absorbing his.
Das Planfilter kann beispielsweise ein Membranfilter sein, z.B. aus einer Polytetrafluoräthylen-Membran. Das Tiefenfil ter kann z.B. aus Keramik oder Kunststoff bestehen. Mikrowellentransparent ist z.B. Polypropylen oder Glas. Mikrowellenabsorbierende Materialien könnten beispielsweise elektrisch leitfähige oder polarisierbare Materialien sein.The plan filter can, for example a membrane filter, e.g. from a polytetrafluoroethylene membrane. The depth filter may e.g. made of ceramic or plastic. Microwave transparent is e.g. Polypropylene or glass. microwave absorbing Materials could for example, electrically conductive or polarizable materials.
Die Frequenz der Mikrowelle kann zwischen 100 MHz und 10 GHz liegen. Normalerweise wird eine Mikrowelle mit einer Frequenz von 2,45 GHz verwendet.The frequency of the microwave can between 100 MHz and 10 GHz. Normally a microwave is used used with a frequency of 2.45 GHz.
Die Sterilisation des Filters durch Mikrowelle kann in bestimmten Zeitintervallen erfolgen. Ferner kann die Sterilisation kontinuierlich durchgeführt werden, indem der Filter als rotierende Scheibe ausgebildet wird, wobei ein Kreissegment der Scheibe der Mikrowellenstrahlung des Mikrowellengenerators ausgesetzt wird, während die Luft außerhalb dieses Segments durch die Scheibe hindurchtritt.Sterilization of the filter Microwave can be done at certain time intervals. Furthermore, can The sterilization can be carried out continuously by the filter is formed as a rotating disk, wherein a circle segment exposed to the disc of the microwave radiation of the microwave generator will, while the air outside this segment passes through the disk.
Die erfindungsgemäße Luftreinigungsanlage ist insbesondere zur Reinigung der Luft im Personeninnenraum von Fahrzeugen, insbesondere von Kraftfahrzeugen, wie Personenkraftwagen oder Omnibussen, aber auch in Flugzeugen oder Gebäuden geeignet.The air purification system according to the invention is in particular for cleaning the air in the passenger compartment of vehicles, in particular motor vehicles, such as cars or buses, but also suitable in airplanes or buildings.
