Beschreibung description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Filters mit biologischem Filtereinsatz zum Geruchlosmachen der bei der Zersetzung von organischen Materialien entstehenden stänkerigen Luft. The invention relates to a method for producing a filter with a biological filter insert for making the stale air produced during the decomposition of organic materials odorless.

Es ist aus der DE-OS 3 537 933 eine Vorrichtung bekannt, deren Wesen darin liegt, dass als Kontaktzone ein Biofilter vorgesehen ist, dessen Rohstoff zweckmässig aus Torfmull besteht. A device is known from DE-OS 3 537 933, the essence of which is that a biofilter is provided as the contact zone, the raw material of which expediently consists of peat garbage.

Die Mängel der bekannten Lösung liegen darin, dass sie von geringer Leistung ist, da der Torfmull unter Einwirkung der Feuchtigkeit eine Schicht bildet, so dass die Vorrichtung leicht verstopft wird. Ferner wird ihre aktive Oberfläche herabgesetzt, wodurch die Bakterienkultur sinkt und die Einrichtung teuer und weniger betriebssicher wird. The shortcomings of the known solution are that it is of low power, since the peat garbage forms a layer under the influence of the moisture, so that the device is easily clogged. Furthermore, its active surface is reduced, which reduces the bacterial culture and makes the device expensive and less reliable.

Gemäss der Erfindung wird ein Verfahren zur Herstellung eines Filters mit biologischem Filtereinsatz zum Geruchlosmachen der bei der Zersetzung von organischen Materialien entstehenden stänkerigen Luft vorgeschlagen, wobei der biologische Filtereinsatz betriebssicher, von hoher Leistung und billig ist. According to the invention, a method for producing a filter with a biological filter insert is proposed to make the stale air produced during the decomposition of organic materials odorless, the biological filter insert being reliable, of high performance and inexpensive.

Die Aufgabe der Erfindung liegt ferner in der Schaffung und Erhaltung einer Bakterienkultur im Filtereinsatz. The object of the invention is also to create and maintain a bacterial culture in the filter insert.

Die gesetzte Aufgabe eingangs genannter Art sollte wie im Patentanspruch definiert gelöst werden. The set task of the type mentioned should be solved as defined in the claim.

Das erfindungsgemässe Verfahren wird anschliessend anhand eines Ausführungsbeispieles ausführlich dargelegt. The method according to the invention is then described in detail using an exemplary embodiment.

Traubenkramm wird aus einer Quetsch-Abbeer-maschine samen- und traubenbeerfrei entnommen und in einen Drehtrommeltrockner mit Heissluft eingeführt, worin er bei hoher Temperatur sterilisiert wird. Dazwischen setzt sich sein Feuchtigkeitsgehalt wenigstens auf 12% herab. Der auf dieser Weise behandelte Traubenkramm wird in ein Filter gebracht, worin er eine Schicht bildet. Grape stuff is removed from a squeeze-berry machine free of seeds and grapes and introduced into a rotary drum dryer with hot air, in which it is sterilized at high temperature. In between, its moisture content drops to at least 12%. The grape crust treated in this way is placed in a filter, in which it forms a layer.

Während des Betriebes wird die stänkerige Luft vor dem Filtrieren von festen Schmutzstoffen und Fett befreit. Der Feuchtigkeitsgehalt der so vorgereinigten Luft wird auf 80-90% erhöht und die Luft durch den erfindungsgemässen biologischen Filtereinsatz hindurch ins Freie geführt. During operation, the stubborn air is freed of solid contaminants and grease before it is filtered. The moisture content of the air pre-cleaned in this way is increased to 80-90% and the air is led outside through the biological filter insert according to the invention.

Messungen mit Olfaktometer haben gezeigt, dass der Wirkungsgrad des Geruchlosmachens zu-wenigst 80% erreicht hat. Measurements with an olfactometer have shown that the efficiency of deodorization has reached at least 80%.

Ein grosser Vorteil des vorgeschlagenen Verfahrens besteht ausser dem ausgezeichneten Wirkungsgrad des Geruchlosmachens hinaus noch darin, dass es die Nutzbarmachung von landwirtschaftlichem Abfall mit physikalischer Methode ermöglicht. A great advantage of the proposed method is, in addition to the excellent efficiency of the odorlessness, that it enables the utilization of agricultural waste with a physical method.
