Abstract

The application relates to a novel method for purifying the exhaust air for vacuum cleaners. The air is given a bactericidal and fungicidal treatment on the basis of alkaline, acidic and neutral layers. Upstream air humidification keeps the chemisorption compositions active.

Description

Es ist bekannt, daß die von Staubsaugern angesaugte und gereinigte Luft auf ihrer Ausblasseite noch eine beträchtlich verunreinigte Luft wieder in das zu säubernde Umfeld abgibt.It is known that the vacuumed and cleaned by vacuum cleaners Air on their exhaust side is still a lot contaminated Releases air back into the environment to be cleaned.

Es wurden deshalb Vorschläge gemacht, zusätzliche Feinstaub­ filter auf der Abluftseite anzubringen.Therefore suggestions have been made, additional fine dust Attach filter on the exhaust air side.

Für empfindliche Menschen und insbesondere für Allergiker reichen diese Maßnahmen jedoch nicht aus.Sufficient for sensitive people and especially for allergy sufferers however, these measures do not rule out.

Es ist erforderlich, auch gasförmige Schadstoffe abzuscheiden und die Filter mit bakterizider und fungizider Wirkung einzusetzen.It is also necessary to separate and remove gaseous pollutants use the filters with bactericidal and fungicidal effects.

Dieser Chemisorptionsfilter wird erfindungsgemäß so aufgebaut, daß die Luft wahlweise stark alkalische Massen durchströmt mit einem pH-Wert von ca. 12, saure Massen mit einem pH-Wert von ca. 1 und danach neutrale Massen.According to the invention, this chemisorption filter is constructed in such a way that that the air flows through strongly alkaline masses with a pH of approx. 12, acidic masses with a pH of approx. 1 and then neutral masses.

Weiterhin wird erfindungsgemäß vorgeschlagen, diese Filter durch Tränkungen von Vlies herzustellen.It is also proposed according to the invention to filter these To produce impregnations of fleece.

Ein weiterer erfindungsgemäßer Gedanke ist die Befeuchtung der Luft hinter dem Motor und vor dem Chemisorptionsfilter, damit die Chemisorptionsmassen immer aktiv bleiben, da durch die Abwärme des Motors die relative Feuchte der Luft verringert wird.Another idea according to the invention is the moistening of the Air behind the engine and in front of the chemisorption filter, so that the Chemisorption masses always remain active because of the waste heat the relative humidity of the air is reduced.

In der Zeichnung ist die erfindungsgemäße Anordnung dargestellt.In the drawing is the arrangement according to the invention shown.

with ( 6 ) the chemisorption filter with strongly alkaline, strongly acidic and neutral layers, whereby this sequence can also be designed as desired;
with ( 7 ) the water reservoir.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und ausgeführten Ausbildungsformen be­ schränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von den Grundgedanken abzuweichen, einen bakteriziden und fungiziden Chemisorptionsfilter auf der Ausblasseite von Staub­ saugern so auszubilden, daß die Luft hinter dem Ventilator zu­ erst eine Befeuchtungseinheit durchströmt, danach eine Filter­ schicht mit stark alkalischem Verhalten, hierauf eine Filter­ schicht mit stark saurem Verhalten und zuletzt eine neutrale Schicht, wobei die Filterschichten aus getränkten Vliesen be­ stehen und auch in einer anderen Reihenfolge angeordnet sein können.Of course, the invention is not based on the above individual types of training described and carried out limits, but there are numerous changes possible without however, deviating from the basic ideas, a bactericidal and fungicidal chemisorption filter on the discharge side of dust sucker so that the air behind the fan is too first flows through a humidification unit, then through a filter layer with strong alkaline behavior, then a filter layer with strongly acidic behavior and finally a neutral one Layer, the filter layers be impregnated nonwovens stand and also be arranged in a different order can.
