Abstract

Ozonisation and/or ionisation are known means for killing off bacilli, viruses, fungi, germs and the like. Ionisation causes additional agglomeration of aerosol particles and/or dust particles. The disadvantage of this conventional system technique resides in the facts that broken ozone channels may have disadvantageous effects on humans or animals and that arrangement in small equipment is problematical. In order to eliminate these disadvantages the invention proposes a portable clean air apparatus provided with a suction nozzle (1) followed by a coarse separating filter (2). This is followed by an ozonisation section (3) leading to a fan (4) whose blow-out side opens via an ionisation section (6) into a space (5). The space (5) is delimited by a chemisorption filter (7) with a diverse layer structure (7a, 7b, 7c). The contaminants killed off by ozonisation and/or ionisation are trapped and bound in sterile fashion in the chemisorption filter (7). <IMAGE>

Zusatzpatentanmeldung zu P 36 20 168.5, datiert vom 13.06.86 mit der Be­ zeichnung "Chemisorptionsfilter zur Behandlung von Atem­ luft für allergieerkrankte Menschen".Additional patent application for P 36 20 168.5, dated 13.06.86 with the Be drawing "Chemisorption filter for the treatment of breath air for allergy sufferers ".

Es ist bekannt, daß durch Ozonisierung und/oder Ionisie­ rung Bazillen, Viren, Pilze und Keime unschädlich ge­ macht werden können.It is known that by ozonization and / or ionization Bacilli, viruses, fungi and germs harmless can be made.

Hinzu kommt, daß durch die Ionisierung eine zusätzliche Agglomeration von Aerosol-Teilchen und/oder auch Staub­ teilchen erbracht wird.In addition, an additional ionization Agglomeration of aerosol particles and / or dust particle is provided.

Der Nachteil dieser Kombinationstechnik liegt darin, daß durchgerissene Ozon-Spuren sich nachteilig auf Mensch und Tier auswirken können, und die Anordnung in kleinen abscheidenden Geräten nicht unproblematisch ist.The disadvantage of this combination technique is that torn ozone traces adversely affect humans and animal can affect, and arrangement in small separating devices is not unproblematic.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, eine Anwendung entsprechend beiliegender Skizze vorzu­ nehmen.For this reason, the invention proposes an application according to the attached sketch to take.

In der beiliegender Skizze ist dargestellt mit (1) der Ansaugstutzen in einem Reinluft-Koffergerät, mit (2) ein Grobfilter, mit (3) die Ozonisierungsstrecke, die einem Ventilator (4) vorgeschaltet ist, wobei erfindungsgemäß durch diese Anordnung vor dem Ventilator eine intensive Kontaktierung des Ozons im Ventilator erzeugt wird und auf der Ausblasseite des Ventilators in einem durch­ strömten Raum (5) zusätzlich eine Ionisierungsstrecke (6) der Ozonisierungsstrecke (3) nachgeschaltet ist, so daß in diesem Bereich eine Agglomeration der Bazillen, Keime, Pilzen, Viren usw., die vorher durch eine Ozoni­ sierung abgetötet worden sind, mit den Staubteilchen stattfindet und in dem agglomerierten (= vergrößerten) Kornspektrum die Partikelzahl in dem nachgesetzten Chemisorptionsfilter (7) mit größtmöglichem Effekt steril eingebunden wird, wobei erfindungsgemäß der Chemisorptionsfilter nicht nur zur Abscheidung der sterilen Bakterien, Pilzen, Viren und Stäuben ausgelegt ist, sondern gleichzeitig eine Sicherheitsfunktion zu erfüllen hat, in dem er durchgerissene Ozonenphasen­ stränge neutralisiert.The attached sketch shows with ( 1 ) the intake manifold in a clean air box unit, with ( 2 ) a coarse filter, with ( 3 ) the ozonization section, which is connected upstream of a fan ( 4 ), whereby according to the invention, an arrangement in front of the fan intensive contacting of the ozone is produced in the fan and an ionization section ( 6 ) is additionally connected downstream of the ozonization section ( 3 ) on the outlet side of the fan in a flow-through space ( 5 ), so that agglomeration of the bacilli, germs, fungi, Viruses etc., which have previously been killed by ozonization, take place with the dust particles and, in the agglomerated (= enlarged) grain spectrum, the number of particles in the subsequent chemisorption filter ( 7 ) is sterile integrated with the greatest possible effect, the chemisorption filter according to the invention not only for Separation of sterile bacteria, fungi, viruses and dusts is designed at the same time it has to fulfill a safety function by neutralizing strands of ozone phases that have been torn through.

Dieses wird erfindungsgemäß dadurch erreicht, indem im Chemisorptionsfilterpaket unter anderen bekannten Chemi­ sorptionsschichten wie A-Kohle, Natronkalk, Eisen-II- und/oder Eisen-III-Salze bzw. und/oder Rasen-Eisenerz, vorzugsweise in einer Konzentration von 80% Fe(OH)3, als Schüttbettsystem der Ozonisierung und Ionisierung nachgeschaltet sind. This is achieved according to the invention in that in the chemisorption filter package, among other known chemisorption layers such as activated carbon, soda lime, iron (II) and / or iron (III) salts and / or turf iron ore, preferably in a concentration of 80% Fe (OH) 3 , downstream of the ozonization and ionization.

Weiterhin wird erfindungsgemäß auch die Reihenfolge die­ ser Chemisorptionsfiltertechnik wie folgt angeordnet:According to the invention, the sequence is also the This chemisorption filter technology is arranged as follows:

  • 1) eine alkalische Chemisorptionsschicht (7 a), bestehend aus: Rasen-Eisenerz, pH-Wert 11-12, Perlite ge­ tränkt mit Natrium-Kaliumcarbonat, pH-Wert ebenfalls 11-12, oder Natronkalk, auch pH-Wert 11-12.1) an alkaline chemisorption layer ( 7 a ), consisting of: turf iron ore, pH 11-12, perlite soaked with sodium potassium carbonate, pH also 11-12, or soda lime, also pH 11-12 .
