Abstract
Description
Die Erfindung bezieht sich auf einen Staubfilter für Klima anlagen, mit einem Filterkörper, in dem in der den Staubfilter durchströmenden Luft enthaltene Partikel sowie Keime, Pilze und Allergene aufgenommen werden.The invention relates to a dust filter for climate plants, with a filter body in which the dust filter Particles flowing through the air as well as germs, fungi and Allergens are included.
Aus dem vielfältigen Einsatz von Staubfiltern in Klimaan lagen ist es bekannt, daß - bei entsprechenden Belastungen der Luft - der Filterkörper eines derartigen Staubfilters nach vergleichsweise kurzer Standzeit verpilzen und ver keimen kann. Abgesehen davon, daß sich durch eine solche Verpilzung und Verkeimung der Strömungswiderstand des Fil terkörpers des Staubfilters beträchtlich erhöht, weist die den Staubfilter durchströmte Luft im Falle einer solchen Verpilzung und Verkeimung einen vergleichsweise unangeneh men Geruch auf. Des weiteren ist es möglich, daß die Ver pilzung und Verkeimung den gesamten Filterkörper durch dringt und daß so Pilze und Keime sowie andere Allergene über die Klimakanäle der Klimaanlage in die von der Klima anlage versorgten Räume eindringen. Abgesehen von der sich hierdurch und durch verwesende Kleinlebewesen erhöhenden Geruchsbelastung kann hierdurch auch eine erhebliche ge sundheitliche Beeinträchtigung vorliegen.From the diverse use of dust filters in air conditioning It is known that - with appropriate loads the air - the filter body of such a dust filter after a comparatively short standing time, fungus and ver can germinate. Apart from the fact that such a Fungal and germ contamination of the flow resistance of the fil body of the dust filter increases significantly, the air flowing through the dust filter in the case of such Fungus and germs a comparatively unpleasant smell. Furthermore, it is possible that the Ver fungus and germs through the entire filter body penetrates and that so fungi and germs and other allergens through the climate channels of the air conditioner into that of the climate system-supplied rooms. Aside from the yourself through this and by decaying small creatures Odor pollution can also be a significant ge there are health impairments.
Grundsätzlich ist es aus dem DE-Buch Wallhäuser "Praxis der Sterilisation, Desinfektion - Konservierung", 3. Aufl., Thieme Verlag Stuttgart 1984, Seiten 90-93, bekannt, daß Säuren und Laugen auf verschiedene Viren eine inaktivierende Wir kung haben.Basically, it is from the DE book Wallhäuser "Praxis der Sterilization, Disinfection - Preservation ", 3rd ed., Thieme Verlag Stuttgart 1984, pages 90-93, known that acids and lye to various viruses an inactivating we have kung.
Der Erfindung liegt die Aufgabe zugrunde, einen Staubfilter für Klimaanlagen zu schaffen, bei dem dauerhaft eine Ver pilzung und Verkeimung des Filterkörpers ausgeschlossen ist.The invention has for its object a dust filter to create for air conditioning systems in which a ver fungus and contamination of the filter body is excluded.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Filterkörper insgesamt oder an seinem der Anströmfläche folgenden Abschnitt mit einer 25%igen Natrium-Kaliumcarbonat- Lösung getränkt ist, die auf 4 Gewichtsanteile Natriumcar bonat 1 Gewichtsanteil Kaliumcarbonat enthält.This object is achieved in that the Filter body as a whole or on its face following section with a 25% sodium potassium carbonate Solution soaked in 4 parts by weight of sodium car bonat contains 1 part by weight of potassium carbonate.
Mittels dieser Maßnahme wird bei Einhaltung des erfindungs gemäßen Gewichtsverhältnisses erreicht, daß der Filterkör per für die vorgegebene Einsatzdauer des Staubfilters gegen eine Verpilzung und Verkeimung gesichert ist.By means of this measure, the invention is adhered to moderate weight ratio achieved that the filter body against for the specified duration of use of the dust filter fungal and germ contamination is ensured.
Vorteilhaft wird der Filterkörper bzw. der seinem der An strömfläche folgende Abschnitt so stark mit Natrium-Kalium carbonatlösung getränkt, daß im Filterkörper bzw. in seinem der Anströmfläche folgenden Abschnitt ein pH-Wert vorliegt, der größer ist als 13. Hierdurch wird eine gesicherte De naturierung aller biologischen Keime und Pilze sowie aller sonstigen Allergene ermöglicht.The filter body or its the An is advantageous flow area following section so strongly with sodium potassium carbonate solution soaked in the filter body or in its the section following the inflow surface has a pH value, which is greater than 13. This ensures a secure De Naturation of all biological germs and fungi as well as all other allergens.
Der vorstehend beschriebene Staubfilter kann in einfacher Weise hergestellt werden, indem der Filterkörper mit einer wäßrigen Lösung von Natriumhydroxid (NaOH) und Kalium hydroxid (KOH) getränkt wird und der derart getränkte Fil terkörper mit Kohlendioxid (CO2) enthaltener Luft durch strömt wird. Nach den UmsetzungsgleichungenThe dust filter described above can be produced in a simple manner by soaking the filter body with an aqueous solution of sodium hydroxide (NaOH) and potassium hydroxide (KOH) and flowing the air through the body so impregnated with carbon dioxide (CO 2 ). According to the implementation equations
2NaOH+CO2=Na2CO3+H2O und2NaOH + CO 2 = Na 2 CO 3 + H 2 O and
2KOH+CO2=K2CO3+H2O2KOH + CO 2 = K 2 CO 3 + H 2 O
entsteht aus dem Natriumhydroxid bzw. dem Kaliumhydroxid Natriumcarbonat bzw. Kaliumcarbonat und Reaktionswasser. Die den Filterkörper durchströmende Luft wird so temperiert, daß in ihr das Reaktionswasser aufgenommen wird. In der wäß rigen Lösung wird ein Gewichtsverhältnis von Natriumhydroxid und Kaliumhydroxid eingehalten, aus dem sich nach der Um setzung ein Gewichtsverhältnis von Natriumcarbonat zu Ka liumcarbonat von 4:1 ergibt.arises from the sodium hydroxide or the potassium hydroxide Sodium carbonate or potassium carbonate and water of reaction. The air flowing through the filter body is tempered in such a way that the water of reaction is taken up in it. In the aq solution becomes a weight ratio of sodium hydroxide and potassium hydroxide, from which after the order setting a weight ratio of sodium carbonate to Ka lium carbonate of 4: 1 results.
Bei einer vorteilhaften Ausführungsform der Erfindung weist ein in Klimaanlagen eingesetzter Staubfilter einen Filter körper auf, in dem die Schadstoffbefrachtung der die Klima anlage durchlaufenden Luft, d. h. Schwebstoffe und Pilze, Keime sowie Allergene aufgenommen werden. Um zu verhindern, daß der Filterkörper von Verpilzung oder Verkeimung betrof fen wird, ist der Filterkörper an seinem der Anströmfläche des Filterkörpers folgenden Abschnitt mit einer 25%igen Natrium-Kaliumcarbonat-Lösung getränkt, die auf 4 Gewichts anteile Natriumcarbonat 1 Gewichtsanteil Kaliumcarbonat enthält. Der Filterkörper ist an dem genannten Abschnitt so stark mit der Natrium-Kaliumcarbonat-Lösung getränkt, daß sich dort ein pH-Wert einstellt, der größer liegt als 13.In an advantageous embodiment of the invention a dust filter used in air conditioners a filter body on which the pollutant loading of the climate air flowing through the system, d. H. Suspended matter and fungi, Germs and allergens are absorbed. To prevent, that the filter body was affected by fungus or germs is, the filter body is on its the inflow surface of the filter body following section with a 25% Sodium potassium carbonate solution soaked to 4 weight proportions of sodium carbonate 1 part by weight of potassium carbonate contains. The filter body is so on the section mentioned heavily soaked with the sodium potassium carbonate solution that itself there sets a pH value that is greater than 13.
