Definitions

  • the invention relates to a filter for gases, in particular air.
  • gases in particular air.
  • filter systems are known, with the help of which pollutants and odorous substances are removed from air streams.
  • Interiors are also called vehicle cabins.
  • the occupants of vehicles, in particular motor vehicles, are exposed to two influences: the so-called pollutants, such as CO, NO x ur.d to a lesser extent S0, which one does not smell or hardly smells, as long as there are no high concentrations, and odorous substances, which are largely from incompletely burned fuel, especially diesel fuel.
  • pollutants such as CO
  • NO x ur.d to a lesser extent S0 which one does not smell or hardly smells, as long as there are no high concentrations
  • odorous substances which are largely from incompletely burned fuel, especially diesel fuel.
  • Pollutants such as CO and NO ⁇ are difficult to eliminate according to the current state of the art and if so, then only with complex, voluminous filter systems for which there is normally no space.
  • the dust layer also contains biologically active material (bacteria, fungal spores) which, under suitable ambient conditions of temperature and air humidity, become in a germ state or one Propagation state come.
  • biologically active material bacteria, fungal spores
  • the microbiological growth can lead to an explosive increase and colonization of the filter media, to the growth of the filter media, to the development of smells and protein-containing pollutants.
  • the main advantage of the invention is that biocidal materials are added to the adsorbing material with a long-term effect. A slow and steady release of the biocidal active ingredient permanently kills germinable material in the particle layer and therefore cannot trigger microbiological growth.
  • the adsorption filter layer consists of activated carbon or polymeric adsorbents, silica gel or zeolite.
  • a preferred one Mixing ratio for the biocidal additive is in a proportion of 3 to 30%, preferably 10% of the area dimensions of the adsorption filter layer. This ensures, on the one hand, that a high adsorption volume is available, and, on the other hand, that the biocidal effect is sufficient to effectively kill spores or live fungi capable of germination even under unfavorable environmental conditions.
  • Iodine or triiodide which is bound in a polymer or activated carbon adsorbent, is suitable as a biocidal additive.
  • the filter is constructed in the form of a combination filter, i. H. it consists of a carrier layer, a filtration layer and a filtering cover layer.
  • a combination filter i. H. it consists of a carrier layer, a filtration layer and a filtering cover layer.
  • the filter material can be a three-dimensional filter structure which consists of an open-cell carrier structure in which adsorbents and biocidal agents are embedded or glued.
  • a combination filter material consisting of carrier layer, filtration layer and particle layer is e.g. B. known from EP 8 8 230. This contains 440 g / m 2 activated carbon and was exposed to a long-term test. In this experiment, outside air was continuously pumped over a period of 12 months with a flow rate of 150m 3 / h air and the adhering particulate and harmful gases were filtered. In the dust layer which had formed on the particle filter layer, a number of 85 CFU / cm 2 (nucleating unit / cm 2 ) of yeasts was found. With overlays in a growth-promoting environment, 48 hours at 23 ° C, 80% rel. Humidity, an increase in the population to 4000 CFU / cm 2 was observed.
  • biocidally effective combination filter material apparently kills germinable spores as well as living fungi.
  • Filter materials containing activated carbon which are based on a three-dimensional, open-cell foam structure, have been used in supply air filtration since 1992.
  • the adsorption filters are usually installed behind a particle filter. The operating time is often up to 5 years. Due to the residual permeability of the particle filter media for fine particles and microorganisms, the adsorptive filter elements are exposed to microorganisms over the long period of use.
  • a biocidal filter material was prepared so that 20% of the iodinated polymer, described by WO 94/06296, was homogeneously mixed with the coal before the adsorbents were connected to the foam structure. The mixture was connected to the foam structure. Such a filter showed only 6 CFU / cm 2 filter surface after the endurance test.
