Abstract

The invention relates to a process for the utilisation of cellulose-rich residues from built-up areas - in particular domestic refuse - from agriculture and forestry, and from commercial establishments by processing to give a briquetted fuel without the residues having to be dried. By spraying propionic acid onto the compressed mass or by mixing propionates into the compressed mass, a briquette of cellulose-rich residues can be produced which is storable for a prolonged period in spite of a moisture content of 20 - 30%. The quantity of added propionic acid or propionates depends on the desired or demanded storage period. It is in general between 0.05 and 5%, preferably 0.1 to 1%.

Description

Die Erfindung betrifft ein Verfahren gemäß Ober-The invention relates to a method according to upper

begriff des Patentanspruchs 1 und eine Anlage zur Durchführung des Verfahrens.term of claim 1 and an attachment to carry out the Procedure.

In der letzten Zeit sind eine Reihe von Verfahren bekannt geworden, durch die Abfall durch Zerklei--nern, Sieben, Sichten und Trocknen so aufbereitet wird, daß hieraus ein lager- und transportfähiger Brennstoffbrikett gepreßt werden kann, (s. z.B.A number of procedures have recently become known by which waste is processed in this way through shredding, sieving, sifting and drying is that from this a storable and transportable fuel briquette can be pressed can, (see e.g.

DE-PS 31 28 560). Nachteilig an einem solchen Verfahren ist der erhebliche Trocknungsaufwand, der in der Größenordnung von 1 GJ/t Hausmüll liegt.DE-PS 31 28 560). The disadvantage of such a process is that it is considerable Drying effort, which is in the order of magnitude of 1 GJ / t household waste.

Die Trocknung auf eine Restfeuchte von üblicherweise 8 - 12 0% ist erforderlich, da sonst die aus Rückständen gewonnenen. Briketts in kurzer Zeit, d.h., im Bereich weniger Tage einem starken Pilzbefall unterliegen, was sich in einer Schimmelbildung zeigt.The drying to a residual moisture content of usually 8-12 0% is required, as otherwise those obtained from residues. Briquettes in a short time, i.e., are subject to severe fungal attack within a few days, which is reflected in shows mold growth.

Hieraus folgt, daß Briketts aus ungetrocknetem Abfall nicht lagerfähig sind und kurzfristig verbrannt werden müssen.It follows that briquettes made from undried waste cannot be stored and need to be burned at short notice.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art anzugeben, mit dem ein lagerfähiges Brikett ohne Trocknung hergestellt werden kann.The invention is based on the object of a method of the above specified type with which a storable briquette is produced without drying can be.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs Irergebenen Merkmale gelöst.According to the invention, this object is achieved by the characterizing features of the patent claim Fixed inaccurate features.

Die weitere Ausbildung des Verfahrens geht aus den Unteransprüchen 2 bis 4 hervor.The further development of the method is based on the subclaims 2 to 4 emerge.

Der niit der Erfindung erzielte Vorteil besteht darin, daß verfahrensgemäß hergestellte Briketts.The advantage achieved by the invention is that according to the method manufactured briquettes.

trotz einer Feuchte von 20 - 30 % über längere Zeit lagerfchhig sind.can be stored for a long time despite a humidity of 20 - 30%.

In der Zeichnung ist an einem Fließbildschema ein Beispiel einer Anlage zur Gewinnung eines brikettierten oder peiletierten Brennstoffs aus zellulosereichen Rückständen dargestellt. Im weiteren ist die Zeichnung erläutert: Ein aus Rückständen -z. B. aus Hausmüll- bestehender unbehandelter Mengenstrom 1 durchläuft eine erste Behandlungsstrecke 2; darin findet eine partielle Zerkleinerung insbesondere ein Aufreißen von Gebinden statt. Das Feinkorn 3 wird abgesiebt, die schweren, grobstückigen Bestandteile werden als Siebüberlauf 4 ausgetragen und leichtes, flugfähiges Material 5 absaugt. Die abgesaugte Leichtfraktion wird in einem Prallreißer 6 zerkleinert bzw. zerfasert. Auf ein Transportband 7, das die zerkleinerte Leichtfraktion zur Brikettpresse 8 transportiert, wird rropionsäure 9 aufgesprüht.The drawing shows an example of a plant using a flow diagram for the extraction of a briquetted or pelleted fuel from cellulose-rich Residues shown. The drawing is explained below: One from residues -z. B. from household waste existing untreated mass flow 1 passes through a first Treatment line 2; Partial comminution takes place therein in particular Tearing open containers instead. The fine grain 3 is sieved off, the heavy, coarse ones Components are discharged as sieve overflow 4 and are light, airworthy material 5 sucks. The light fraction sucked off is crushed in an impact ripper 6 or frayed. On a conveyor belt 7, which the crushed light fraction to Briquette press 8 transported, rropionic acid 9 is sprayed on.

Bei einer anderen vorteilhaften Ausführung des Verfahrens werden der abgesaugten Leichtfraktion 6 Propiate 10 zudosiert. In der anschließenden Zerkleinerung 6 erfolgt dann eine innige Durchmischung des Leichtgutes mit dem chemischen Additiv.In another advantageous embodiment of the method, the sucked off light fraction 6 Propiate 10 metered in. In the subsequent crushing 6 the light material is then thoroughly mixed with the chemical additive.
