Abstract

The Main Application P 3620666.0 relates to a method for separating off dusts, moulds, viruses, germs, bacilli and gaseous and/or aerosol pollutants, in which an ozonisation section and an ionisation section are connected upstream of a chemisorption filter package. To improve the separation efficiency, according to the invention it is proposed that the individual chemisorption filter layers (3) are provided with electrostatically charged and/or chargeable separating filter cloths (2) between the individual chemisorption compositions (3) and/or a dielectric (4) separates the individual electrically conducting layers from each other so that a field build-up is possible between the electrically conducting layers, and/or the housing (5) of the chemisorption filter package (3) and/or the intermediate layers are electrically connected to a high voltage generator in such a manner that, in interaction with an ioniser acting on the opposite pole, they produce an improved agglomeration between the chemisorption filter layers with simultaneous upstream connection of a high voltage ozone generator. <IMAGE>

Weiterhin wird erfindungsgemäß vorgeschlagen, daß das Chemisorptionsfilterpaket und/oder die zwischen­ gelagerten Trennschichten zwischen den einzelnen Chemisorptionsmassen als Di-Electricum ausgeführt sind.2. Furthermore, it is proposed according to the invention that the chemisorption filter package and / or the between stored separating layers between the individual Chemisorption masses executed as Di-Electricum are.
  • 3. Weiterhin wird erfindungsgemäß vorgeschlagen, daß auf der Gasaustrittsseite ein ozonempfindlicher Sensor angeordnet ist, der die Funktion der Sicher­ heit übernimmt, d. h. bei einer vorgegebenen Durch­ rißphase von Ozon nicht nur z. B. einer Anzeige zuführt, sondern über einen monostabilen Schalt­ kreis die Ozonisierungsstrecke abschaltet.3. Furthermore, it is proposed according to the invention that on the gas outlet side an ozone sensitive Sensor is arranged, the function of the safe unit takes over, d. H. at a given through crack phase of ozone not only z. B. an ad feeds, but via a monostable switching circuit switches off the ozonization path.
