Abstract
Description
Die Erfindung betrifft ein Verfahren zum wassersparenden Waschen von laufenden Warenbahnen gemaß dem einleitenden Teil des Anspruchs 1 und eine zum Durchführen des Verfahrens geeignete Vorrichtung gemäß dem einleitenden Teil des Anspruchs 5.The invention relates to a method for water-saving washing of moving webs according to the introductory part of
Gemäß EP 0 197 429 A1, auf der die Erfindung aufbaut, wird umgewälzte Waschflotte - abgesehen von einer am Wareneinlauf vorgesehenen Düsenanordnung zum Abspritzen von Flusen - den einzelnen Behandlungsabteilen ausschließlich durch Flachstrahldüsen zugeführt, die jeweils am Ausgang des Behandlungsabteils angeordnet sind. Dabei wird die in einem Behandlungsabteil gesammelte Waschflotte insbesondere einem anderen Behandlungsabteil zugeführt, in dem die Behandlung der Ware weiter fortgeschritten ist.According to EP 0 197 429 A1, on which the invention is based, circulated washing liquor - apart from a nozzle arrangement for spraying fluff at the goods inlet - is fed to the individual treatment compartments exclusively through flat jet nozzles, which are each arranged at the exit of the treatment compartment. The washing liquor collected in one treatment compartment is in particular fed to another treatment compartment in which the treatment of the goods has progressed further.
Durch die DE 33 24 650 A1 ist ein Verfahren zur Naßbehandlung von breit geführten laufenden Warenbahnen bekannt, bei dem in den Behandlungsabschnitten zugeführte Behandlungsflotte nach dem Behandlungsvorgang aufgefangen, dem gleichen Behandlungsvorgang erneut zugeführt und erst danach aus dem Behandlungsabschnitt abgeführt bzw. in den nächsten Behandlungsabschnitt weitergeleitet wird. Bei Behandlungsabschnitten mit vertikaler Führung der Warenbahn sind zwei Spritzrohre beiderseits des ersten hochlaufenden Warenbahnabschnitts und zwei weitere Spritzrohre oberhalb der letzten beiden Oberwalzen angeordnet.From DE 33 24 650 A1, a method for wet treatment of broadly running webs of goods is known, in which the treatment liquor supplied in the treatment sections is collected after the treatment process, fed to the same treatment process again and only then removed from the treatment section or passed on to the next treatment section becomes. In the case of treatment sections with vertical guidance of the web, two spray pipes are arranged on both sides of the first ramping up web section and two further spray pipes above the last two top rollers.
Bei einem Behandlungsabschnitt mit horizontaler Warenbahnführung sind Spritzrohre in der Nähe der drei unteren Umlenkwalzen angeordnet.In the case of a treatment section with a horizontal web guide, spray pipes are arranged in the vicinity of the three lower deflection rollers.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, durch bessere Ausnutzung der Waschflotte eine erhebliche Einsparung an frischem Waschtwasser zu erzielen und somit die Betriebskosten zu senken. Eine weitere Aufgabe besteht darin, eine zur Durchführung des Verfahrens geeignete Vorrichtung zu schaffen.The present invention has for its object to achieve a considerable saving in fresh wash water by better utilization of the wash liquor and thus reduce operating costs. Another object is to provide a device suitable for carrying out the method.
Die erste Aufgabe wird durch das im kennzeichnenden Teil des Anspruchs 1 angegebene Merkmal gelöst. Weitere vorteilhafte Merkmale des erfindungsgemäßen Verfahrens sind den Ansprüchen 2 bis 4 zu entnehmen.The first object is achieved by the feature specified in the characterizing part of
Die zweite Aufgabe wird durch das im kennzeichnenden Teil des Anspruchs 5 angegebene Merkmal gelöst. Weitere vorteilhafte Merkmale der erfindungsgemäßen Vorrichtung sind den Ansprüchen 6 bis 15 zu entnehmen.The second object is achieved by the feature specified in the characterizing part of claim 5. Further advantageous features of the device according to the invention can be found in claims 6 to 15.
Anhand der beiliegenden Zeichnungen soll die Erfindung nachfolgend noch weiter erlautert werden. Auf den Zeichnungen zeigen
- Fig. 1 das Behandlungsflottenführungsschema gemäß der Erfindung und
- Fig. 2 ein Ausführungsbeispiel für eine erfindungsgemäße Vorrichtung in stark schematisierter Darstellung.
- Fig. 1, the treatment fleet management scheme according to the invention and
- Fig. 2 shows an embodiment of a device according to the invention in a highly schematic representation.
Bei dem Flottenführungsschema der Fig. 1 ist die Warenbahn 10 nur angedeutet, um die Darstellung nicht zu verwirren. Der vollständige Lauf der Warenbahn durch die Behandlung ist in Fig. 2 dargestellt. In beiden Figuren sind gleiche Teile mit gleichen Bezugszeichen versehen.In the fleet management scheme of FIG. 1, the
Wie Fig. 1 erkennen läßt, sind in dem Gehäuse 11, welches von der Warenbahn bei der Behandlung durchlaufen wird, Verteilerrohre 25, 26, 27 und Flachstrahldüsen 28, 29,30,38 angedeutet. durch die der Warenbahn die Behandlungsflotte zugeführt wird. Die von der Warenbahn ablaufende Flotte wird am Boden jedes Abteils 12, 13, 14 für jedes Abteil getrennt abgeführt und in Auffangbehältern 15, 16, 17, 18 gesammelt. Aus diesen Behältern wird die Behandlungsflotte über Pumpen 19,20,21,22 jeweils in das gleiche Abteil im Kreislauf zurückgefördert und über die Verteilerohre und Flachstrahldüsen wieder der Warenbahn zugeführt. Die geförderten Flottenmengen können durch Regelventile in den Zuleitungen eingestellt werden, wie die Figur erkennen läßt.As can be seen in FIG. 1,
Der Umwälzung der Behandlungsflotte ist eine Führung der Flotte im Gegenstrom zur Laufrichtung der Warenbahn durch die Behandlung überlagert, die dadurch erreicht wird, daß die Auffangbehälter 15, 16, 17, 18 kaskadenförmig mit Überläufen in der Weise angeordnet sind, daß die Flotte von den Auffangbehältern der Bereiche weiter fortgeschrittener Behandlung zu den Auffangbehältern der in der Behandlung weiter voran liegenden Auffangbehälter, also entgegen der Laufrichtung der Warenbahn durch die Behandlung zurückgeführt wird. Die Flottenerneuerung erfolgt durch Überlauf der als Frischwasser eingespeisten Wassermenge von Auffangbehälter zu Auffangbehälter.The circulation of the treatment liquor is superimposed on the guidance of the liquor in countercurrent to the direction of travel of the fabric through the treatment, which is achieved in that the
Um die Auffangbehälter herum ist ein Siebband 23 geführt, durch das die von der Warenbahn ablaufende Flotte sofort von abfiltrierbaren Verunreinigungen befreit wird. Die Reinigung des Siebbandes geschieht nach der Passage des letzten am niedrigsten angeordneten Auffangbehälters durch Abspritzen mit einem Teilstrom des Abwassers mittels Düsen 24 von innen her. Es wird also kein Frischwasser zur Reinigung verbraucht. Das Band wird kurz nach der Stelle gereinigt, an der die größte Menge an abfiltrierbarer Substanz zu erwarten ist. Das Siebband 23 läuft ständig langsam in Richtung des Flottenlaufes durch die Auffangbehälter um.A
In Fig. 1 ist noch die Aufheizung des kalten Frischwassers 34 über eine Abwasser-Wärmerückgewinnungseinrichtung mit Wärmetauscher 35, einem mit Heizdampf 36 in Verbindung stehenden Nacherhitzer 37, sowie den dazugehörigen Ventilen und Regeleinrichtungen angedeutet. Außerdem lassen sich verschiedene Möglichkeiten für besondere Flottenführungen hinter den Auffangbehältern, wie Unterbrechung 40, Umführung 39, Ableitung 42 usw. erkennen, durch die eine optimale Waschleistung mit geringstem Frischwasserverbrauch für unterschiedliche Betriebserfordernisse ermöglicht wird.In Fig. 1, the heating of the cold
Das Ausführungsbeispiel einer erfindungsmäßigen Vorrichtung der Fig. 2 läßt den genauen Lauf der Warenbahn 10 durch die aufeinanderfolgenden Waschabteile 12, 13, 14 erkennen, sowie die Flottenführungen. Die einzelen Bezeichnungen sind die gleichen wie in Fig. 1.The embodiment of a device according to the invention of FIG. 2 reveals the precise running of the
Die Warenbahn 10 wird über ein Wasserschloß 31 in das Abteil 12 im dampfdichten Gehäuse 11 eingeführt. Im Einlaufbereich wird die Warenbahn zunächst mit der schmutzigsten Flotte beidseitig durch Flachstrahlen 38 abgespritzt. Damit werden oberflächliche Verunreinigungen abgespü-It und die Konzentration der auszuwaschenden Substanzen in der Ware bereits deutlich herabgesetzt.The
Die Zuführung der Flotte zur Warenbahn in den einzelnen Abteilen 12, 13, 14 erfolgt dann in der Weise, die bei Fig. 1 bereits beschrieben ist. Ebenso die Kreislaufführung und die Gegenstromführung der Behandlungsflotte.The supply of the fleet to the web in the
Am Ende der Behandlung verläßt die Warenbahn 10 das Gehäuse 11 wieder über ein Wasserschloß 33 und kann dann einem Endquetschwerk 41 zugeführt werden, womit dann die Waschbehandlung abgeschlossen ist.At the end of the treatment, the
