Abstract

Die Erfindung betrifft ein Verfahren zur Trocknung von Fasergut (3), in dem das zu trocknende Fasergut (3) in einen Behälter (2) eines Trockners (1) gefüllt wird und ein Trockengas (8) durch das Fasergut (3) geleitet wird sowie einen Trockner (1) zur Trocknung von Fasergut (3) mit einem im oberen Bereich eines Behälters (2) des Trockners (1) angeordneten Eintritt (9) für ein Trockengas (8), mit einem im oberen Bereich des Behälters (2) angeordneten Anschluss (4) für zu trocknendes Fasergut (3), mit einem im unteren Bereich des Behälters (2) angeordneten Abzug (15) für ein getrocknetes Fasergut (14), mit einem im unteren Bereich des Behälters (2) angeordneten Austritt (13) für ein Feuchtgas (12).The invention relates to a process for drying fibrous material (3) in which the fibrous material (3) to be dried is filled into a container (2) of a dryer (1) and a drying gas (8) is passed through the fibrous material (3) and a dryer (1) for drying fibrous material (3) with an inlet (9) for a drying gas (8) arranged in the upper region of a container (2) of the dryer (1), with one arranged in the upper region of the container (2) Connection (4) for fibrous material (3) to be dried, with a deduction (15) for a dried fibrous material (14) arranged in the lower region of the container (2), with an outlet (13) arranged in the lower region of the container (2). for a wet gas (12).

Um ein Trocknungsverfahren und einen Trockner für Fasergut mit einfacher Anlagentechnik zur Verfügung zu stellen, wird vorgeschlagen, dass das zu trocknende Fasergut (3) von oben in den Behälter (2) in Form einer Schüttung eingebracht wird, das Trockengas (8) in einen oberen Bereich der Schüttung aus Fasergut (3) eingeleitet wird, das Trockengas (8) nach unten durch die Schüttung aus Fasergut (3) strömt und als ein mit Feuchtigkeit aus dem Fasergut (3) beladenes Feuchtgas (12) aus einem unteren Bereich der Schüttung, der unterhalb des oberen Bereich der Schüttung aus Fasergut (3) liegt, abgeleitet wird.

Figure imgaf001
In order to provide a drying method and a dryer for fibrous material with simple system technology, it is proposed that the fibrous material to be dried (3) from above into the container (2) is introduced in the form of a bed, the dry gas (8) in an upper 3) is introduced, the drying gas (8) flows down through the bed of fibrous material (3) and as a wet gas (12) laden with moisture from the fibrous material (3) from a lower region of the bed, which is below the upper portion of the bed of fibrous material (3), is derived.
