Abdeckung für zwangsbelüftete biologisch aktive HaufwerkeCover for forced-ventilation biologically active heaps
Es ist bekannt, daß zwangsbelüftete biologisch aktive Haufwerke wie z.B. Biofilterschüttungen
- hier wird der zu reinigende Luftstrom durch eine biologisch aktive Schüttschicht (Kompost, Torf, etc.) geleitet - aufgrund der starken Durchströmung,
Keime und Pilzsporen freisetzen können. Diese Keime und Pilzsporen können unter ungünstigen Umständen zu Gesundheitsgefährdung beitragen.
Gleichzeitig ist bekannt, daß durch starke Sonneneinstrahlung Biofilterschüttungen
an der Oberfläche austrocknen, oder bei starken Regenfällen übernässen können,
beides Effekte, die in der Regel unerwünscht sind.It is known that forced-ventilation of biologically active material such as biofilters - where the air flow to be cleaned is passed through a biologically active layer of material (compost, peat, etc.) - can release germs and fungal spores due to the strong air flow. These germs and fungal spores can, under unfavourable circumstances, pose a health risk.
At the same time, it is known that strong sunlight can dry out the surface of biofilter beds or cause them to become over-wetted during heavy rainfall, both effects that are generally undesirable.
Bei großen Biofiltern geht man zunehmend dazu über diese einzuhausen und dadurch witterungsunabhängig zu machen und die gefaßte Abluft kontrolliert über Kamin abzuleiten, nicht zuletzt um die unkontrollierte diffuse Freisetzung von Keimen zu verhindern. Diese Abluftführung führt aber lediglich zur Verdünnung und besserer Verteilung, nicht aber zur Vermeidung besagter Emissionen. Weiterhin sind diese Einhausungen vor allem bei großen Flächenfiltern - hier sind Flächen von über 1000 m2 keine Seltenheit - sehr kostspielig.With large biofilters, there is an increasing trend to enclose them, making them weatherproof and to discharge the collected exhaust air in a controlled manner via a chimney, not least to prevent the uncontrolled diffuse release of germs. However, this exhaust air routing only leads to dilution and better distribution, but not to the prevention of said emissions. Furthermore, these enclosures are very expensive, especially with large surface filters - areas of over 1000 m 2 are not uncommon.
Folienabdeckungen zur Minderung der Witterungseinflüsse auf Kompostmieten wurden schon eingesetzt. Allerdings werden diese Mieten nicht oder nur sehr schwach belüftet und die Folie hat lediglich die Funktion Regenwasser abzuleiten. Bei Biofiltern dagegen wird funktionsbedingt eine möglichst hohe Durchströmung der Schüttung erwünscht. Aufgrund der hohen Luftdurchsätze (bis zu 200 rri Abluft je Quadratmeter Filterfläche und Stunde) konnten hier bisher keine Folien eingesetzt werden.Film covers to reduce the effects of the weather on compost heaps have already been used. However, these heaps are not ventilated or only very weakly ventilated and the film only serves the function of draining rainwater. In the case of biofilters, on the other hand, the highest possible flow through the fill is desired for functional reasons. Due to the high air flow rates (up to 200 rri exhaust air per square meter of filter area and hour), films have not yet been able to be used here.
Aufgabe der vorliegenden Erfindung ist es eine kostengünstige Möglichkeit zur Vermeidung von gesundheitsgefährdenden Keim- und Sporenemissionen aus Biofiltern und gleichzeitig einen möglichst effektiven Schutz vor Witterungseinflüssen zu schaffen.The object of the present invention is to create a cost-effective way of preventing harmful germ and spore emissions from biofilters and at the same time providing the most effective possible protection against weather influences.
Die Aufgabe wird gelöst durch die in Anspruch 1 angegebene folien- oder plattenförmige Abdeckung. Die aus dem durchströmten Haufwerk (Kompost, Humus, Torf, etc.) austretende Luft kann durch die feinen poren- und schlitzförmigen Öffnungen austreten, während Keime und Pilzsporen sowie Staubpartikel und feine Flüssigkeitstropfen zurüchgehalten werden.The problem is solved by the film or plate-shaped cover specified in claim 1. The air escaping from the flowing material (compost, humus, peat, etc.) can escape through the fine pore and slot-shaped openings, while germs and fungal spores as well as dust particles and fine liquid drops are retained.
Durch die feine Struktur der Öffnungen mit sehr kleinen Durchmessern, wird das Eindringen der o.g. Teilchen verhindert und die Abdeckung ist damit verstopfungsfrei. The fine structure of the openings with very small diameters prevents the penetration of the above-mentioned particles and the cover is therefore free from clogging.
Die Abdeckung kann ohne nennenswerte Probleme auf bestehende, beliebig große Flächen aufgebracht werden. Sie bewirkt gleichzeitig einen Witterungsschutz.The cover can be applied to existing surfaces of any size without any significant problems. It also provides protection from the weather.
Durch die in Anspruch 2 angegebene Bewässerungseinrichtung kann unter der Abdeckung bei Bedarf bewässert werden.The watering device specified in claim 2 allows watering to be carried out under the cover if required.
Durch die in Anspruch 3 angegebene Aufständerung kann die Abdeckung in einem bestimmten Abstand zur abzudeckenden Oberfläche angebracht werden.By means of the mounting specified in claim 3, the cover can be mounted at a certain distance from the surface to be covered.
Die in den Ansprüchen 4 und 5 angegebene Eigenschaft ermöglicht den gezielten Einsatz zum Regulieren der Sonneneinstrahlung auf die Filterfläche.The property specified in claims 4 and 5 enables targeted use to regulate the solar radiation on the filter surface.
