Abstract
Description
Kennwórt: "Müll-AltpapierauSbereitung" Verfahren zur Herstellung von Grundstoff für die Papierherstellung aus Altpapier Die Erfindung betrifft ein Verfahren zur Herstellung von Grundstoff für die Herstellung von Papier unter Verwendung von Altpapier.Kennwórt: "waste paper processing" process for the production of Base material for papermaking from waste paper The invention relates to a method for the production of base material for the production of paper using Waste paper.
Aus Haushaltsmüll wird Altpapier ussortiert, um in der Papierindustrie bei der Papierherstellung weiterverwendet zu werden. Dieses Altpapier ist mit Bakterien und Kleinstlebewesen stark verseucht, es hat einen starken Müllgeruch, ist nicht lagerfähig, da es einen relativ hohen Feuchtigkeitsgehalt von etwa 20 ffi hat, zersetzt sich leicht und kann zu Infektionen beim Personal führen. Es belastet außerdem den Wasserkreislauf der Papierfabrik.From household waste, waste paper is sorted out in the paper industry to be reused in papermaking. This waste paper is contaminated with bacteria and microorganisms heavily contaminated, it has a strong garbage odor, is not storable because it has a relatively high moisture content of around 20 ffi, decomposes easily and can lead to infections in staff. It also burdens the Water cycle of the paper mill.
Aufgabe der Erfindung ist es daher, ein Verfahren zu schaffen, das eine möglichst billige und einfache Aufbereitung des Altpapiers aus Haushaltsmüll u.ä. gestattet.The object of the invention is therefore to create a method that the cheapest and simplest possible processing of waste paper from household waste etc. allowed.
Die Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1.The object is achieved according to the invention by the features of the characterizing Part of claim 1.
Das dementsprechend behandelte Altpapier aus Altmüll ist Je nach Behandlungsdauer und Ozonmenge weitgehend geruchsfrei, die Mikroorganismen sind abgetötet. Daher kann das Altpapier nach dieser Aufbereitung gelagert werden, ohne daß Zersetzungsprobleme auStreten,und die Infektionsgefahr ist ebenfalls behoben. Ozon hat den Vorteil, daß es sich nach ca. 20 Minuten in den in der Luft normalerweise in größeren engen enthaltenen Luftsauerstoff umwandelt. Der entstandene Sauerstoff ist dementsprechend unschädlich. Daher ist die Verwendung von Ozon der Verwendung von Chlor in gewisser Weise vorzuziehen. Es hat sich auch gezeigt, daß das erfindungsgemäße Verfahren zur Behandlung von Müll-Altpapier sehr günstig ist, da nur ein geringer Verbrauch an Desinfektionsmitteln auftritt.The appropriately treated waste paper from waste waste is depending on the duration of treatment and amount of ozone largely odorless, the microorganisms are killed. Therefore the waste paper can be stored after this processing without any decomposition problems occur, and the risk of infection is also eliminated. Ozone has the advantage that after about 20 minutes in the air it is usually in larger tight spaces converts contained atmospheric oxygen. The resulting oxygen is accordingly harmless. Hence, the use of ozone is similar to the use of chlorine to a certain extent Way preferable. It has also been shown that the method according to the invention for the treatment of waste paper is very cheap, since only a low consumption of disinfectants occurs.
Da die Zuführung des Desinfektionsmittels bei der normalen Aussortierung des Altpapieres aus dem Müll in Windsichtern er: folgt, sind keine besonderen Zusatzeinrichtungen nötig, als nur die die ZufUhrung des Desinfektionsmittels in den Blaswind herbeiführen. Es ist auch mögliche eine Nachsortierung vorzunehmen, indem z.B. vorher das Altpapier in kleinere Bestandteile zerrissen wird und die Zuführung des Desinfektionsmittels bei der Nachsortierung in ebenfalls verwendeten Windsichtern vorgenommen wird.Since the supply of the disinfectant during normal sorting of the waste paper from the garbage in air separators follows, there are no special additional devices necessary than just bringing the disinfectant into the wind. It is also possible to re-sort, e.g. by removing the waste paper beforehand is torn into smaller components and the supply of the disinfectant is carried out during the subsequent sorting in air separators that are also used.
