"Verfahren zur Trennung des Plastikmaterials vom Papier in festem Stadtmüll""Procedure for separating the plastic material from the paper in solid urban waste"

Die Erfindung betrifft ein Verfahren zur Trennung des Plastikmaterials vom Papier in festem Stadtmüll.The invention relates to a method for separating the plastic material from the paper in solid urban waste.

Es sind bereits verschiedene Verfahren bekannt geworden, mit denen man versucht, das Plastikmaterial vorn Papier in festem Stadtmüll grob voneinander zu trennen. In Anbetracht der physikalischen und chemischen Eigenschaften der beiden Materialien wird aber eine intensive Trennung derselben meist unmöglich gemacht.Various methods have already become known with which one tries to remove the plastic material from paper to be roughly separated from each other in solid urban waste. Considering the physical and chemical properties However, an intensive separation of the two materials is usually made impossible.

Weiters ist die Trennung eines Plastikgebröckeis von zermahlenem Papier schwierig, zumal auch ein Zyklonensystem keine sichere und wirkungsvolle Trennung der beiden Materialien gewährleistet.Furthermore, the separation of a plastic lump from the ground paper is difficult, especially since a cyclone system no safe and effective separation of the two materials is guaranteed.

ORIGiNAL INSPECTEDORIGiNAL INSPECTED

Der Erfindung liegt daher die Aufgabe zugrunde, es durch ein Verfahren zu ermöglichen, in befriedigender Weise das Plastikmaterial vom Papier zu trennen, wobei das Verfahren bei einem festen Stadtmüll angewandt wird, der schon einer sogenannten Vorauswahl unterzogen worden ist.The invention is therefore based on the object of to enable a method to satisfactorily separate the plastic material from the paper, the method is applied to solid urban waste that has already been subjected to a so-called pre-selection.

Das erfindungsgemäße Verfahren stützt sich hauptsächlich auf einer physikalisch-chemischen Umformung des Plastikmaterials durch Einwirkung von Hitze, wobei die Umwandlung bzw. Umformung nur das Plastikmaterial betrifft, während das Papier seine Eigenschaften nicht nur unverändert aufrechterhält, sondern noch verstärkt.The method according to the invention is mainly based on a physico-chemical reshaping of the plastic material by the action of heat, the transformation or reshaping only affecting the plastic material, while the paper not only maintains its properties unchanged, but also strengthens them.

Das erfindungsgemäße Verfahren besteht daher vor allem darin, daß das aus Papier und dünnscMchtigem Plastikmaterial bestehende, bereits einer Vorauswahlbehandlung unterzogene und somit aus zerkleinerten Materialien gebildete Produkt einer Austrocknungsbehandlung unterzogen wird. Nach Erreichen des gewünschten Austrocknungsgrades wird das Produkt mittels geeigneter Hitzequellen einer eigentlichen Heizwirkung ausgesetzt, wobei das Produkt Temperaturen auch über 100° C erreichen kann.The method according to the invention therefore consists primarily in the fact that the paper and thin plastic material existing, already subjected to a preselection treatment and thus formed from shredded materials The product is subjected to a desiccation treatment. After reaching the desired degree of drying the product is exposed to an actual heating effect by means of suitable heat sources, whereby the product Temperatures can also reach over 100 ° C.

Durch die Wirkung dieser Erhitzung erfährt das dünnschichtige Plastikmaterial eine Art SEtirumpfung und ballt sich in kleine Klumpen oder Knoten zusammen, dieDue to the effect of this heating, the thin-layer plastic material experiences a kind of swelling and agglomerates into small lumps or knots that

Ein Teil des Plastikmaterials unterliegt weiters auch einem Verflüchtigungseffekt mit folgender Umwandlung im Dampf.then fall to the bottom of the heating vessel and possibly get stuck there on pieces of paper. A part of the plastic material is also subject to further a volatilization effect with the following transformation in the steam.

Nach der vorgenannten Viär me behandlung wird das Produkt abgekühlt, wobei das Plastikmaterial die Haftfestigkeit verliert. Das abgekühlte, aus Plastikmaterial und Papier bestehende Produkt kann nun einerSiebbehandlung unterzogen werden, bei der sich das Papier vom Staub und Gebröckel beSeit, die bisher aufgrund der Umgebungsbedingungen (im festen Stadtmüll) diesem anhafteten, und das Plastikmaterial scheidet z.B. zusammen mit dem Staub in Krümelform aus. Die Siebbehandlung könnte aber auch nicht unbedingt erforderlich sein, da wegen der kleinen Abmessungen der Krümel des Plastikmaterials letzteres a.uch während des Zerquetschvorganges des Papiers ausgesondert werden könnte.After the aforementioned Viär me treatment, the product cooled, whereby the plastic material loses its adhesive strength. The cooled, made of plastic material and The existing paper product can now be subjected to a screen treatment in which the paper is removed from the dust and crumbs that previously adhered to it due to the environmental conditions (in solid urban waste), and the plastic material precipitates out in the form of crumbs, for example, together with the dust. The sieve treatment could, however also not absolutely necessary, because of the small dimensions of the crumbs of the plastic material the latter could also be separated out during the crushing process of the paper.

Es ist erfindungsgemäß des weiteren vorteilhaft, daß die Austrocknungs- und Wärmebehandlung sowie die Abkühlungsund Siebbehandlung von einem geeigneten mechanischen Effekt begleitet werden; denn ein solcher mechanischer Effekt begünstigt sowohl die Trennung des Papiers vom Plastik-It is also advantageous according to the invention that the drying and heat treatment as well as the cooling and sieving treatment of a suitable mechanical effect to be accompanied; because such a mechanical effect favors the separation of the paper from the plastic
