Abstract
The heat exchanger to be used for regulating the temp. of the dye liquor in a drum machine, is a double walled vessel, with, in the inner chamber an inlet and an outlet for the working liquor. Between the inner and outer wall, a sealed intermediate chamber has an inlet and an outlet for the cooling medium. A coil for the heating fluid is arranged in the inner chamber, which is coaxial with the outer wall of the vessel. The dye liquor can be heated or cooled by the systems which are completely independent of each other. The operating temp. can be selected with reference to all the factors- type of material to be dyed, the dyestuffs, additives, rate of flow, etc. Adjustments can be made quickly and the cooling down period before extn. is shortened.
Description
Die Erfindung bezweckt, einen kombinierten Wärmeaustauscher zu schaffen, insbesondere für Textilfärbeprozesse, durch welche die den Wärmeaustauscher durchströmende Arbeitsflüssigkeit, insbesondere die Färbeflotte, sowohl aufheizbar wie auch abkühlbar ist, wobei das Aufheizen und das Abkühlen unabhängig voneinander steuerbar sind.
Die optimale Färbetemperatur der Färbeflotte ist von verschiedenen Faktoren abhängig, zum Beispiel von den zu färbenden Textilien, vom Farbstoff, von Bad-Zusätzen und von der Bewegung der Färbeflotte. Dabei spielt die genaue Temperatureinhaltung beim Färbeprozess eine wesentliche Rolle für die Güte der gefärbten Erzeugnisse. In vielen Fällen steigt auch der maximal erreichbare Ausnutzungsgrad der Färbeflotte, wenn kurz vor dem Herausnehmen der Textilien das Färbebad abgekühlt wird. Um die erwähnten Erfordernisse zu erfüllen, sind bekannte Färbemaschinen zusätzlich zur Heizanordnung mit einer separaten Kühlanordnung versehen. Dadurch lassen sich Temperaturabweichungen rasch auskorrigieren, und die Auskühlzeitspanne vor dem Herausnehmen des Materials wird verkürzt.
Bisherige Heiz- und Kühlanordnungen als separate Elemente, z. B. in das Färbebad getauchte Heiz- und Kühlschlangen, waren unbefriedigend, da sie konstruktiv aufwendig waren und die genaue Temperatureinhaltung schwierig war.
Es wurde daher nach neuen Wegen gesucht, durch welche die gestellte Aufgabe zweckmässiger gelöst werden konnte.
Der erfindungsgemässe Wärmeaustauscher hebt sich dadurch hervor, dass er ein doppelwandiges Gefäss aufweist, in dessen Innenraum eine Eingangs- und eine Ausgangsleitung für die Arbeitsflüssigkeit münden, dass zwischen der Aussenwand und der Innenwand ein dicht verschlossener Zwischenraum vorhanden ist, in welchem ein Kühlmedium über Anschlussstutzen zirkulierbar ist, und dass ein Rohr für ein Heizmedium den Innenraum durchdringt.
Anhand der einzigen Zeichnung, welche einen Längsschnitt durch einen Wärmeaustauscher und schematisch dessen Anschluss an eine Färbe-Trommelmaschine darstellt, wird nachfolgend ein Ausführungsbeispiel der Erfindung näher erläutert.
Der Wärmeaustauscher 1 weist einen doppelwandigen Zylinder auf, welcher oben und unten mit einem Deckel 2 bzw.
mit einer Bodenplatte 3 verschlossen ist. Dabei ist ein Innenzylinder 4 koaxial in einem Aussenzylinder 5 angeordnet und an den Enden direkt mit dem Aussenzylinder 5 verbunden, derart, dass zwischen den Zylindern, 4, 5 ein dicht verschlossener Zwischenraum 6 entsteht, in welchem ein Kühlmedium 7 zirkulierbar ist. In der Wand des Aussenzylinders 5 ist ein Eintritts- und ein Austrittsstutzen 8, bzw. bis 9 angebracht durch welche das Kühlmedium 7, z. B. Kaltwasser, unten in den Zwischenraum 6 eingeführt wird und oben wieder weggeführt wird.
Eine Eingangs- und eine Ausgangsleitung 10 bzw. 11 für die Färbeflotte 12 münden in den Innenraum 13 des Wärmeaustauschers 1. Zum Aufheizen der Färbeflotte 12 ist eine Rohrschlange 14 für ein Heizmedium 15 vorgesehen, welche den Innenraum 13 durchdringt. Als Heizmedium 15 kann zweckmässig Dampf, Heissöl oder überhitztes Wasser Verwendung finden.
Die unten am Wärmeaustauscher 1 angeschlossene Eingangsleitung 10 ist über eine Pumpe 16 und einen Filter 17 mit der Färbetrommelmaschine 18 verbunden. Die mittels der Pumpe 16 durch den Wärmeaustauscher 1 gedrückte Färbeflotte 12 fliesst durch die oben am Wärmeaustauscher 1 angeschlossene Ausgangsleitung 11 wieder in die Färbetrommelmaschine 18 zurück.
Durch den vorliegenden Wärmeaustauscher kann die Temperatur der Färbeflotte in engen Grenzen gehalten und auch rasch geändert werden. Dabei wird das Heizmedium und das Kühlmedium nach gesteuertem Programm dem Wärmeaustauscher separat zugeführt.
Die Verwendung des Wärmeaustauschers beschränkt sich selbstverständlich nicht nur auf Färbemaschinen.

**WARNUNG** Ende DESC Feld konnte Anfang CLMS uberlappen**.
The aim of the invention is to create a combined heat exchanger, in particular for textile dyeing processes, through which the working fluid flowing through the heat exchanger, in particular the dye liquor, can be both heated and cooled, the heating and cooling being controllable independently of one another.
The optimum dyeing temperature of the dye liquor depends on various factors, for example the textiles to be dyed, the dye, bath additives and the movement of the dye liquor. The exact maintenance of temperature during the dyeing process plays an essential role for the quality of the dyed products. In many cases, the maximum achievable degree of utilization of the dye liquor also increases if the dye bath is cooled down shortly before the textiles are removed. In order to meet the requirements mentioned, known dyeing machines are provided with a separate cooling arrangement in addition to the heating arrangement. This allows temperature deviations to be corrected quickly and the cooling-off period before the material is removed is shortened.
Previous heating and cooling arrangements as separate elements, e.g. B. heating and cooling coils immersed in the dye bath, were unsatisfactory because they were structurally complex and it was difficult to maintain the exact temperature.
It was therefore looked for new ways by which the task could be solved more appropriately.
The heat exchanger according to the invention is distinguished by the fact that it has a double-walled vessel, in the interior of which an inlet and an outlet line for the working fluid open, and that between the outer wall and the inner wall there is a tightly closed space in which a cooling medium can be circulated via connecting pieces is, and that a pipe for a heating medium penetrates the interior.
On the basis of the single drawing, which shows a longitudinal section through a heat exchanger and schematically its connection to a dyeing drum machine, an embodiment of the invention is explained in more detail below.
The heat exchanger 1 has a double-walled cylinder, which is covered with a cover 2 or
is closed with a base plate 3. An inner cylinder 4 is arranged coaxially in an outer cylinder 5 and connected directly to the outer cylinder 5 at the ends in such a way that a tightly closed space 6 is created between the cylinders 4, 5 in which a cooling medium 7 can be circulated. In the wall of the outer cylinder 5, an inlet and an outlet nozzle 8, or 9 through which the cooling medium 7, z. B. cold water, is introduced below into the space 6 and is led away again above.
An inlet and an outlet line 10 and 11 for the dye liquor 12 open into the interior space 13 of the heat exchanger 1. To heat the dye liquor 12, a pipe coil 14 is provided for a heating medium 15 which penetrates the interior space 13. Steam, hot oil or superheated water can expediently be used as the heating medium 15.
The inlet line 10 connected at the bottom of the heat exchanger 1 is connected to the dyeing drum machine 18 via a pump 16 and a filter 17. The dye liquor 12 pressed through the heat exchanger 1 by means of the pump 16 flows back into the dye drum machine 18 through the outlet line 11 connected at the top of the heat exchanger 1.
The present heat exchanger allows the temperature of the dye liquor to be kept within narrow limits and also changed quickly. The heating medium and the cooling medium are fed separately to the heat exchanger according to a controlled program.
The use of the heat exchanger is of course not limited to dyeing machines.
