Abstract
Die Anmeldung betrifft einen Stromtrockner zum Trocknen eines faserförmigen Produkts, mit einem Transportrohr (14, 17, 20) für einen kreislaufförmigen Prozessgasstroms, in dem eine Eintragsschleuse (15) zum Eintragen von zu trocknendem Produkt (16) in den Prozessgasstrom, eine Austragsschleuse (18) zum Austragen von getrocknetem Produkt (19) aus dem Prozessgasstrom, ein Ventilator (21) zur Aufrechterhaltung des Prozessgasstroms durch das Transportrohr (14, 17, 20) und eine Abzweigungsvorrichtung (24) zum Ausscheiden eines Teils des Prozessgases aus dem Prozessgasstromkreislauf angeordnet sind, und zeichnet sich dadurch aus, dass die Abzweigungsvorrichtung (24) in dem Ventilator (21) angeordnet ist. Die Anmeldung betrifft weiterhin ein entsprechendes Trocknungsverfahren.The application relates to a flow dryer for drying a fibrous product, with a transport pipe (14, 17, 20) for a circular process gas flow, in which an inlet lock (15) for introducing product (16) to be dried into the process gas flow, a discharge lock (18 ) for discharging the dried product (19) from the process gas flow, a fan (21) for maintaining the process gas flow through the transport pipe (14, 17, 20) and a branching device (24) for separating part of the process gas from the process gas flow circuit are arranged, and is characterized in that the branching device (24) is arranged in the fan (21). The application also relates to a corresponding drying process.
Description
Die Erfindung betrifft einen Stromtrockner zum Trocknen eines faserförmigen Produkts nach dem Oberbegriff von Anspruch 1.The The invention relates to a flow dryer for drying a fibrous product according to the preamble of claim 1.
Bei bekannten Stromtrocknern ist die Austragsschleuse als Zyklon ausgeführt. Hierdurch kann ein hoher Staubabscheidungsgrad erreicht werden, jedoch ergibt sich bei den üblichen Durchflussmengen eine erhebliche Bauhöhe des Zyklons.at known power dryers, the discharge lock is designed as a cyclone. hereby a high degree of dust separation can be achieved, however results yourself at the usual Flow rates a considerable height of the cyclone.
Zur
Reduzierung der Bauhöhe
ist es beispielsweise aus
Die Aufgabe der vorliegenden Erfindung besteht darin, einen Stromtrockner bereitzustellen, bei dem der apparative Aufwand reduziert ist und der eine verringerte Bauhöhe ermöglicht.The The object of the present invention is a stream dryer to provide, in which the expenditure on equipment is reduced and the reduced height allows.
Die Erfindung löst diese Aufgabe mit den Mitteln der Ansprüche 1 und 9. Durch die Anordnung der Abzweigungsvorrichtung in dem Ventilator kann der Aufwand verringert werden, da auf eine separate Abluftabzweigung hinter dem Ventilator verzichtet werden kann.The Invention solves This object by the means of claims 1 and 9. By the arrangement the branching device in the fan, the effort can be reduced be there on a separate exhaust branch behind the fan can be waived.
Ein besonderer Vorzug besteht darin, dass mittels des Ventilators, im Gegensatz zu der einfachen Abzweigung wie aus der WO 2005 000043 A1 bekannt, eine Staubanreicherung in der ausgeschiedenen Abluft und daher eine Reinigung der Prozessluft erreicht werden kann.One particular advantage is that by means of the fan, in the Contrary to the simple branch as in WO 2005 000043 A1 known, a dust accumulation in the excreted exhaust air and therefore a purification of the process air can be achieved.
Falls erforderlich kann hinter der Abzweigungsvorrichtung eine Staubabscheidungsvorrichtung beispielsweise in Form eines Zyklons angeordnet sein. Aufgrund der geringeren Durchflussmenge der ausgeschiedenen Abluft kann dieser eine wesentlich verringerte Bauhöhe im Vergleich zu einem im Prozessstrom angeordneten Zyklon aufweisen.If required behind the branching device, a dust removal device be arranged for example in the form of a cyclone. Due to the lower flow rate of the excreted exhaust air can this a significantly reduced height compared to a cyclone arranged in the process stream.
