Description
Die Erfindung betrifft ein Verfahren zur Aufbereitung einer hauptsächlich aus nichtmetallischen Stoffen bestehenden Gutfraktion, die bei der Zerkleinerung von Schrott, Müllschrott und/oder Müll beispielsweise in Shreddern oder Mühlen anfällt.The invention relates to a method for processing a mainly from non-metallic substances existing good fraction, which in the crushing of Scrap, rubbish and / or garbage, for example, in shredders or mills.
Nach einem bekannten Verfahren zur Aufbereitung einer beim Shredderprozeß entstehenden Gutfraktion unterschiedlicher Korngröße werden nach Abtrennung von Metallen die Bestandteile der Fraktion in einem Doppelkammer-Extruder kompaktiert. In Vorbereitung einer thermischen Verwertung erfolgt eine Zerkleinerung der im Doppelkammer-Extruder hergestellten Preßlinge, eine Klassierung des zerkleinerten Produktes zur Auswahl einer geeigneten Korngröße und abschließend gegebenenfalls eine nochmalige Abtrennung von verbliebenen Metallen.According to a known method for processing a shredder The resulting good fraction of different grain sizes are separated of metals the constituents of the fraction in a double chamber extruder compacted. In preparation for thermal recycling, a Crushing of the compacts produced in the double-chamber extruder, one Classification of the shredded product to select a suitable grain size and finally, if necessary, the remaining ones are separated again Metals.
Bei der Durchführung des Verfahrens hat sich als nachteilig erwiesen, daß aus dem Zerkleinerungsprozeß nur eine vergleichsweise geringe Anzahl von Partikeln hervorgeht, die die erforderliche Korngröße besitzt und damit über die Klassierung für das weitere Verfahren zur Verfügung steht. Im Ergebnis liegt ein Korngrößenspektrum vor, welches die Forderungen an für eine thermische Verwertung geeignete Ausgangsstoffe überwiegend nicht erfüllt.When carrying out the method has proved disadvantageous in that the comminution process only a comparatively small number of particles emerges, which has the required grain size and thus on the classification for which further procedure is available. The result is a Grain size spectrum that meets the requirements for a thermal Utilization of suitable starting materials mostly not fulfilled.
Des weiteren ist aus der DE 43 25 948 A1 ein Verfahren zur Schaffung von Wertstoffen aus Hausmüll bekannt. Bei diesem Verfahren wird das Ausgangsprodukt einer Schlag- und Zerkleinerungswirkung ausgesetzt. In einer drehenden wendelförmigen Leiteinrichtung erfolgt eine Agglomeration des zerkleinerten Produktes unter Zuführung von Wärme. Im Ergebnis dieses Prozesses entsteht durch Verkleben der Partikel ein kompaktes Produkt, welches bezogen auf die Korngröße inhomogen und einer Vereinzelung ohne Einbeziehung weiterer Verfahrensschritte nicht zugänglich ist.Furthermore, DE 43 25 948 A1 describes a method for creating Recyclable materials known from household waste. With this procedure, that is Base product exposed to an impact and crushing effect. In A rotating helical guide device agglomerates of the shredded product with the addition of heat. As a result of this Process, a compact product is created by gluing the particles, which is inhomogeneous in relation to the grain size and a separation without Inclusion of further procedural steps is not accessible.
Der Erfindung liegt daher die Aufgabe zugrunde, ein solches Verfahren dahingehend zu verbessern, daß ein relativ breiter Bereich des Korngrößenspektrums der die Gutfraktion bildenden Bestandteile einer thermischen Verwertung zugänglich wird. The invention is therefore based on the object of such a method to improve in that a relatively wide range of Grain size spectrum of the constituents of a good fraction thermal recycling becomes accessible.
Diese Aufgabe wird erfindungsgemäß gelöst, indem an Bestandteile der Gutfraktion thermoplastische Kunststoffe gebunden werden, die eine Vereinzelung der gebundenen Bestandteile für eine thermische Verwertung derselben ermöglichen.This object is achieved in that components of the Good fraction of thermoplastic materials are bound, one Separation of the bound components for thermal recycling enable the same.
Mit der Erfindung ist insbesondere der Vorteil verbunden, daß die zwischen den Bestandteilen der Fraktion und den thermoplastischen Kunststoffen aufgebaute Bindung zu einer Homogenisierung der gebundenen Bestandteile hinsichtlich ihrer Korngröße führt.The invention has the particular advantage that the between the Components of the fraction and the thermoplastics built Binding to homogenization of the bound components with regard to their Grain size leads.
Desweiteren sind die Bindungskräfte innerhalb der durch thermoplastische Kunststoffe gebundenen Bestandteile der Fraktion erheblich größer als die Bindungskräfte, die zwischen den Bestandteilen aufgebaut werden können. Damit ist stets eine Vereinzelung beispielsweise in Form des Einblasens der Partikel in einen Prozeßraum möglich.Furthermore, the binding forces within are due to thermoplastic Plastics bound components of the fraction significantly larger than that Binding forces that can be built up between the components. In order to is always a separation, for example in the form of blowing the particles in a process room possible.
Hinzu kommt, daß eine Durchführung des Verfahrens mit vergleichsweise geringem Energieaufwand möglich ist.In addition, the method is carried out comparatively low energy consumption is possible.
In zweckmäßiger Ausführung der Erfindung erfolgt zur Erhöhung der Effizienz des Verfahrens vor der Bindung der thermoplastischen Kunststoffe an Bestandteile der Gutfraktion eine Abtrennung und/oder Bildung eines bestimmten Korngrößenbereiches aus der Gutfraktion in ihrer Gesamtheit.In an expedient embodiment of the invention, the efficiency of the Process before the binding of the thermoplastics to components of the Gutfraction a separation and / or formation of a certain Grain size range from the good fraction in its entirety.
Um eine weitgehend gleichmäßige Bindungsstruktur der einzelnen Partikel zu schaffen, wird der thermoplastische Kunststoff in einem Mischprozeß über die Bestandteile der Gutfraktion verteilt. Während einer Agglomerationsphase wird daraufhin eine Bindung zwischen den einzelnen Bestandteilen der Fraktion und den thermoplastischen Kunststoffen herbeigeführt, wonach das Agglomerationsgut eine Abkühlphase durchläuft.To ensure a largely uniform binding structure for the individual particles create, the thermoplastic in a mixing process on the Components of the good fraction distributed. During an agglomeration phase thereupon a bond between the individual components of the fraction and brought about the thermoplastic, after which the agglomeration good goes through a cooling phase.
Als Weiterbildung des Verfahrens ist vorgesehen, insbesondere dann, wenn aus den Bestandteilen der Gutfraktion selbst keine thermoplastischen Kunststoffe teilweise entzogen und umverteilt werden können, aus thermoplastischen Kunststoffen bestehende Folien vorzugsweise in zerkleinerter Form der aufzubereitenden Gutfraktion in Vorbereitung des Agglomerationsprozesses zuzugeben.A further development of the method is provided, in particular when the components of the good fraction itself no thermoplastic can be partially withdrawn and redistributed from thermoplastic Plastic existing foils preferably in crushed form Good fraction to be prepared in preparation for the agglomeration process to admit.
