Description

Die vorliegende Erfindung betrifft einen Trockner für eine textile Warenbahn mit zumindest einem Trocknerraum, in dem wenigstens eine luftdurchlässige Trommel drehbar angeordnet ist, die von der Warenbahn teilweise umschlingbar ist und wobei die Warenbahn mit erwärmter Trocknungsluft durchströmbar ist, und wobei ein Ventilator vorgesehen ist, mit dem aus einer Öffnung der Trommel feuchte Trocknungsluft aus der Innenseite der Trommel absaugbar und eine Umwälzung der Trocknungsluft zurück in den Trocknerraum bildbar ist, und wobei eine Wärmezufuhr eingerichtet ist, mit der der Trocknungsluft Wärme zuführbar ist.The present invention relates to a dryer for a textile material web with at least one dryer space, in which at least one air-permeable drum is rotatably arranged, which is partially wrapped by the web and wherein the web with heated drying air can be flowed through, and wherein a fan is provided with the moist air drying from an opening of the drum from the inside of the drum sucked and a circulation of the drying air back into the dryer room can be formed, and wherein a heat supply is arranged, with the drying air heat can be supplied.

Die DE 10 2012 109 878 B4 offenbart einen Trockner für eine textile Warenbahn mit einem Trocknerraum, in dem mehrere luftdurchlässige Trommeln drehbar angeordnet sind, die von der Warenbahn teilweise umschlingbar sind und wobei die Warenbahn mit erwärmter Trocknungsluft durchströmt wird. Weiterhin ist jeder Trommel ein Ventilator zugeordnet, mit dem aus einer Öffnung der Trommel feuchte Trocknungsluft aus der Innenseite der Trommel absaugbar und eine Umwälzung der Trocknungsluft zurück in den Trocknerraum bildbar ist und wobei eine Wärmezufuhr eingerichtet ist, mit der der Trocknungsluft Wärme zuführbar ist.The DE 10 2012 109 878 B4 discloses a dryer for a textile web having a dryer space in which a plurality of air-permeable drums are rotatably arranged, which are partially wrapped by the web and wherein the web is passed through with heated drying air. Furthermore, each fan is associated with a fan, with the humid drying air from the inside of the drum can be sucked from an opening of the drum and a circulation of the drying air back into the dryer room is formed and wherein a heat supply is arranged, with the drying air heat can be supplied.

Zum Wärmeeintrag, der zur Aufheizung der Trocknungsluft notwendig ist, dienen Heizelemente, die im Heizungs- und Ventilatorraum angeordnet sind. Die Heizelemente sind derart angeordnet, dass diese vom Luftstrom der vom Ventilator radial oder tangential abströmenden Trocknungsluft umströmt werden. Sind beispielsweise drei Trommeln vorgesehen, um die die textile Warenbahn nacheinander herumgeführt wird, so sind auch drei wenigstens teilweise voneinander getrennte Trocknungsluft-Kreisläufe vorgesehen, und jeder Trocknungsluft-Kreislauf wird durch einen zugeordneten Ventilator erzeugt. Dabei werden auch jedem Trocknungsluft-Kreislauf eigene Heizelemente zugeordnet, sodass die Wärmezufuhr in jeden Trocknungsluft-Kreislauf separat erfolgt.For heat input, which is necessary for heating the drying air, serve heating elements, which are arranged in the heating and fan room. The heating elements are arranged such that they are from the air flow of the fan radially or tangentially flowing drying air to be flowed around. If, for example, three drums are provided, around which the textile web is guided one after the other, three drying air circulations, which are at least partially separated from each other, are also provided, and each drying air circuit is generated by an associated fan. In this case, each heating air circuit own heating elements are assigned, so that the heat is supplied separately in each drying air circuit.

Läuft die textile Warenbahn über eine Einlaufwalze ein und umschlingt nacheinander die Trommeln, so erfolgt die Trocknung der textilen Warenbahn schrittweise nacheinander. Der Entzug der Feuchtigkeit der textilen Warenbahn erfolgt dabei nicht in jedem Trocknerraum gleichmäßig und mit einem konstanten Trocknungsgradienten, vielmehr durchläuft die textile Warenbahn mit mehreren Trocknerräumen eine Trocknungskaskade, und der Trocknungsgrad der textilen Warenbahn, die den Trockner über eine Auslaufwalze wieder verlässt, sollte eine geforderte Restfeuchte aufweisen. Die Trocknung erfolgt dabei idealerweise mit einem minimalen Energieeintrag in den Trockner, sodass beispielsweise eine Restfeuchte von 8 % in der textilen Warenbahn beim Verlassen des Trockners vorliegt, und sodass der Energieeintrag über die Wärmezufuhr und über den Betrieb des Ventilators für den gesamten Trockner minimal sein sollte.If the textile material web runs over an inlet roller and wraps around the drums one after the other, then the drying of the textile material web occurs stepwise one after the other. The removal of the moisture of the textile web is not uniform in each dryer room and with a constant Trocknungsgradienten, but the textile web passes through a drying cascade with several dryer rooms, and the degree of drying of the textile web that leaves the dryer on a discharge roll again, should have a required Have residual moisture. The drying is ideally carried out with a minimum energy input into the dryer, so for example, a residual moisture content of 8% in the textile web when leaving the dryer, and so that the energy input via the heat and the operation of the fan for the entire dryer should be minimal ,

Um einen Trockner energieminimal zu betreiben, muss dieser mit verschiedenen Parametereinstellungen für einzelne Qualitäten und Anfangsfeuchtigkeiten der textilen Warenbahn betrieben werden, und der Energieverbrauch muss zur Erzielung einer geforderten Restfeuchte ermittelt werden. Bekannt sind Trockner mit mehreren Trommeln, bei denen allerdings nur für den gesamten Trockner die Trocknungsleistung bestimmt werden kann. Diese Bestimmung erfolgt durch eine Messung der Anfangsfeuchte der Warenbahn beim Eintritt in den Trockner und durch eine Messung der Endfeuchte der Warenbahn beim Austritt aus dem Trockner.In order to operate a dryer energy-minimally, it must be operated with different parameter settings for individual qualities and initial moistures of the textile web, and the energy consumption must be determined to achieve a required residual moisture. Known are dryers with several drums, which, however, only for the entire dryer, the drying performance can be determined. This determination is made by measuring the initial moisture content of the web when entering the dryer and by measuring the final moisture content of the web when exiting the dryer.

Bekannte Messungen der Warentemperatur, insbesondere der Kühlgrenztemperatur, sind für einen Trommeltrockner ungeeignet, da die Temperaturmessung in der Regel berührungslos erfolgt und vorwiegend die Temperatur der Trommel selbst gemessen wird und nicht die Temperatur der Warenbahn. Der Grund dafür liegt darin, dass in der Regel die Masse der Ware im Vergleich zur Masse der Trommel um ein Vielfaches geringer ist. Folglich erfolgt eher eine Messung der Temperatur der Manteloberfläche der Trommel und nicht eine Messung der Temperatur der textilen Warenbahn.Known measurements of the product temperature, in particular the cooling limit temperature, are unsuitable for a drum dryer, since the temperature measurement is usually non-contact and predominantly the temperature of the drum itself is measured and not the temperature of the web. The reason for this is that, as a rule, the mass of the product is many times smaller compared to the mass of the drum. Consequently, a measurement of the temperature of the mantle surface of the drum rather than a measurement of the temperature of the textile web takes place.

Zur Verringerung des Energieeintrags pro Masse an zu trocknender textiler Ware sind Einrichtungen zur Wärmerückgewinnung bekannt, durch die ein Teil des Energieverlustes durch die heiße Abluft dem Trocknungsprozess wieder zuführbar ist, wie in der DE 10 2012 109 878 B4 beschrieben. Die Einrichtung zur Wärmerückgewinnung ermöglicht dabei jedoch keine Optimierung des Feuchteklimas in den Trocknerräumen derart, dass eine weitere Energiereduktion zum Betrieb des Trocknungsprozesses möglich wird.To reduce the energy input per mass of fabric to be dried fabric heat recovery facilities are known, by which a part of the energy loss through the hot exhaust air to the drying process can be fed again, as in DE 10 2012 109 878 B4 described. However, the device for heat recovery does not allow optimization of the humidity climate in the dryer rooms in such a way that a further energy reduction to operate the drying process is possible.

Aufgabe der Erfindung ist die Weiterbildung eines Trockners zur Trocknung einer textilen Warenbahn und die Weiterbildung eines Verfahrens zum Betrieb eines solchen Trockners, wobei der Trockner und das Verfahren eine Trocknung der textilen Warenbahn mit einem möglichst minimalen Energieeinsatz ermöglichen sollen.The object of the invention is the development of a dryer for drying a textile web and the development of a method for operating such a dryer, wherein the dryer and the method to allow drying of the textile web with the least possible use of energy.

Die Erfindung schließt die technische Lehre ein, dass in oder stromabwärts hinter der Öffnung der Trommel ein Feuchtemesselement angeordnet ist, mit dem der Feuchtegrad der aus der Innenseite abgesaugten Trocknungsluft messbar ist, und erfindungsgemäß weist der Trockner eine Steuerung auf, die dazu ausgebildet ist, wenigstens die Wärmezufuhr in Abhängigkeit des gemessenen Feuchtegrades der aus der Innenseite abgesaugten Trocknungsluft zu steuern.The invention includes the technical teaching that a moisture measuring element is arranged in or downstream of the opening of the drum, with which the degree of moisture of the sucked drying air from the inside can be measured, and according to the invention, the dryer has a control that is designed to at least to control the heat input as a function of the measured moisture level of the extracted from the inside drying air.

Kerngedanke der Erfindung ist die Optimierung des Trocknungsprozesses, bei der eine Beurteilung des Trocknungsgrades in jeder Trocknungszone des Trockners zugrunde gelegt wird, wobei jede Trocknungszone durch einen separaten Trocknerraum gebildet wird. Die erfindungsgemäße Vorgehensweise ist dabei die Weiterbildung eines Trockners mit wenigstens einem Feuchtemesselement, das den Feuchtegrad der aus der Innenseite der Trommel abgesaugten Trocknungsluft misst, nachdem die textile Warenbahn von der Trocknungsluft durchströmt wurde. Auf Basis der geforderten Restfeuchte der textilen Warenbahn beim Verlassen des Trockners werden folglich die Trocknungsleistung für jeden einzelnen Trocknungsraum beurteilt und optimiert. Hierfür dient erfindungsgemäß die Steuerung, die dazu ausgebildet ist, die Wärmezufuhr in Abhängigkeit des gemessenen Feuchtegrades der aus der Innenseite abgesaugten Trocknungsluft zu steuern. Weiterführend ist die Steuerung auch dazu ausgeführt, die elektrische Leistung des Ventilators zu steuern, welcher ebenfalls einen Verbraucher darstellt.The core idea of the invention is the optimization of the drying process, which is based on an assessment of the degree of drying in each drying zone of the dryer, wherein each drying zone is formed by a separate dryer space. The procedure according to the invention is the development of a dryer with at least one moisture measuring element, which measures the degree of moisture of the drying air extracted from the inside of the drum after the textile web has been passed through by the drying air. On the basis of the required residual moisture of the textile web when leaving the dryer, the drying performance for each individual drying space is consequently assessed and optimized. For this purpose, according to the invention, the control is used, which is designed to control the heat supply as a function of the measured moisture level of the extracted from the inside drying air. In addition, the controller is also designed to control the electric power of the fan, which also constitutes a consumer.

Damit die spezifische Verdampfungsleistung bezogen auf die Durchströmgeschwindigkeit der Trocknungsluft durch die textile Warenbahn bestimmt werden kann, ist zusätzlich zur Feuchtemessung in oder hinter der Öffnung der Trommel in Richtung zum Ventilator ein Strömungsmesselement vorgesehen, das die Strömungsgeschwindigkeit misst und welches Messsignal an die Steuerung übermittelt wird.So that the specific evaporation power can be determined by the textile web in relation to the flow rate of the drying air, in addition to the moisture measurement in or behind the opening of the drum in the direction of the fan, a flow measuring element is provided which measures the flow velocity and which measurement signal is transmitted to the control.

Eine vorteilhafte Weiterbildung des Trockners sieht vor, dass dieser mehrere Trommeln mit mehreren den Trommeln zugeordneten Ventilatoren aufweist, wobei in den Öffnungen der Trommeln jeweils ein Feuchtemesselement angeordnet ist, und wobei die Steuerung dazu ausgebildet ist, wenigstens die Wärmezufuhr an die jeweils umgewälzte Trocknungsluft in Abhängigkeit des jeweils gemessenen Feuchtegrades der Trocknungsluft aus den Trommeln zu steuern. Die Wärmezufuhr wird dabei durch Heizelemente, durch den Trocknungsräumen zugeordneten Heißgaszufuhreinrichtungen oder dergleichen gebildet, und erfindungsgemäß wird die Steuerung dazu weitergebildet, die einzelnen Heizleistungen der jeweiligen Wärmezufuhr an die Trocknerräume zueinander verschieden einzustellen. Dazu wird jeder Heizleistung der gemessene Feuchtewert zugrunde gelegt, wobei unter Berücksichtigung weiterer Messdaten durch die Steuerung eine optimale Wärmeinbringung berechnet wird, sodass schließlich unter minimalem Energieeinsatz die geforderte Restfeuchte der textilen Warenbahn erreicht wird, mit der diese den Trockner verlässt. Mit Bezug auf eine Gesamt-Heizleistung des Trockners wird somit beispielsweise im ersten Trocknerraum ein höherer Prozentsatz einer Teil-Heizleistung eingebracht, und für den mittleren und den hinteren Trocknerraum herrschen geringere Teil-Heizleistungen vor. Folglich muss durch Anwendung eines entsprechenden Algorithmus die Steuerung die jeweilige Heizleistung der Wärmezufuhren anpassen, wobei die Anpassung vorzugsweise auch über einen kontinuierlichen Trocknungsprozess veränderlich ist. Insbesondere erfolgt die Anpassung auch an die textile Warenbahn, sodass die Textilart, die Qualität, die Eingangsfeuchte und dergleichen der textilen Warenbahn dem Steuerungsprozess zur Einbringung unterschiedlicher Energieeinträge in die Trocknerräume zugrunde gelegt werden.An advantageous development of the dryer provides that it has a plurality of drums with a plurality of fans associated with the drums, wherein in the openings of the drums each a humidity measuring element is arranged, and wherein the controller is adapted to at least the heat supply to the respective circulating drying air in dependence to control the measured moisture level of the drying air from the drums. The heat supply is formed by heating elements, by the drying chambers associated hot gas supply means or the like, and according to the invention the control is further developed to set the individual heating outputs of the respective heat supply to the dryer rooms to each other. For this purpose, the measured moisture value is taken as the basis for each heating power, whereby optimal control of the heat input is calculated by taking into account further measured data, so that the required residual moisture of the textile material web with which it leaves the dryer is finally achieved with minimum energy input. Thus, for example, with respect to a total heating capacity of the dryer, a higher percentage of partial heating power is introduced in the first dryer room, and lower partial heating capacities prevail for the middle and rear dryer rooms. Consequently, by applying an appropriate algorithm, the controller must adjust the respective heat output of the heat supplies, the adjustment preferably also being variable over a continuous drying process. In particular, the adaptation also takes place on the textile material web, so that the textile type, the quality, the input moisture and the like of the textile material web are used as the basis for the control process for introducing different energy inputs into the dryer rooms.

Mit weiterem Vorteil weist der Trockner wenigstens eine Zwischenkammer auf, die der Trommel zugeordnet ist oder die jeweils den Trommeln zugeordnet sind und in die aus der Innenseite der Trommel beziehungsweise den Trommeln abgesaugte Trocknungsluft einströmbar ist, wobei das Feuchtemesselement hinter der Öffnung in der Zwischenkammer angeordnet ist. Sind mehrere Zwischenkammern vorgesehen, so ist vor oder in jeder Zwischenkammer ein Feuchtemesselement hinter der Öffnung angeordnet. Die Zwischenkammern dienen dabei insbesondere zur Abzweigung der Abluft aus der jeweiligen Trocknungsluft und/oder zur Einspeisung von Zuluft durch eine Zulufteinrichtung.With further advantage, the dryer has at least one intermediate chamber, which is assigned to the drum or the respective drums are assigned and in the sucked from the inside of the drum or the drums drying air can be flowed, wherein the moisture measuring element is arranged behind the opening in the intermediate chamber.

Vorteilhafterweise ist die Steuerung derart weitergebildet, dass bei einer geforderten Restfeuchte der textilen Warenbahn bei Verlassen des Trockners die Wärmezufuhren und/oder die Ventilatoren der hintereinander von der textilen Warenbahn durchlaufenen Trocknungsräume mit jeweiligen Energieströmen so versorgt werden, dass ein minimaler Gesamtenergiebedarf erzielt wird.For example, the controller has an energy module and a process module, wherein the energy module is designed to monitor at least the heat supply and / or the fan, and wherein the process module is designed to monitor the at least one moisture measurement element and / or the temperature measurement element.

The volume flow measuring element is advantageously also connected to the controller, and a volume flow signal serves, for example, to support the control of the fans.

Eine weitere vorteilhafte Ausgestaltung des Trockners sieht vor, dass ein Volumenstrommesselement in der Zulufteinrichtung angeordnet ist, und ein weiteres Volumenstrommesselement ist in der Ablufteinrichtung angeordnet. Mittels der Erfassung der Volumenströme der Zuluft und der Abluft kann eine Regelung der Wärmerückgewinnung verbessert gesteuert werden, wobei die Abluft abhängig von der Restfeuchte der textilen Warenbahn eingeregelt wird, und wobei der Volumenstrom der Zuluft in Abhängigkeit des Volumenstroms der Abluft nachgeregelt wird.A further advantageous embodiment of the dryer provides that a volume flow measuring element is arranged in the Zulufteinrichtung, and another volume flow measuring element is arranged in the exhaust device.

Die Steuerung 17 weist ein Energiemodul 24 und ein Prozessmodul 25 auf. Das Energiemodul 24 ist zur Überwachung wenigstens der Wärmezufuhr 15 und/oder des Ventilators 12 ausgebildet und das Prozessmodul 25 ist zur Überwachung des wenigstens einen Feuchtemesselementes 16 und/oder des Temperaturmesselementes 23 ausgebildet. Weiterhin überwacht das Prozessmodul 25 die Messwerte des Feuchtemesselementes 26 in der Abluft 20.The controller 17 has an energy module 24 and a process module 25. The energy module 24 is designed to monitor at least the heat supply 15 and / or the fan 12 and the process module 25 is designed to monitor the at least one moisture measuring element 16 and / or the temperature measuring element 23.

Bei Ausführung des Verfahrens zum Betrieb des Trockners 100 mit der Steuerung 17 auf vorstehend beschriebene Weise wird folglich ein sich selbst energieminimal einjustierender Trockner 100 geschaffen. Die Steuerung 17 des Trockners 100 sorgt dabei für einen minimalen Energiezustrom in die jeweiligen Trocknerräume 10, sodass zur Erzielung der geforderten Restfeuchte der textilen Warenbahn 1 der Energieverbrauch minimiert wird. Die jeweiligen Betriebszustände sind dabei abhängig von der Qualität und der Eingangsfeuchte der textilen Warenbahn, sodass beispielsweise über ein Bedienfeld des Trockners 100 Erfahrungswerte eingegeben werden können, welche Steuerungswerte zur Klimatisierung der einzelnen Trocknerräume 10 notwendig sind. Diese Werte hängen beispielsweise ab von der Qualität, der Dichte, des Flächengewichtes und der Dicke der textilen Warenbahn 10, wobei vorzugsweise auch die Eingangsfeuchte und Ausgangsfeuchte der textilen Warenbahn 10 als Eingangsgröße zur Programmierung der Steuerung 17 und zum Ablauf eines entsprechenden Trocknerprogramms des Trockners 100 berücksichtigt werden.In carrying out the method for operating the dryer 100 with the controller 17 in the manner described above, therefore, a dryer 100 which adjusts itself with minimum energy is created. The controller 17 of the dryer 100 ensures a minimum energy flow into the respective dryer rooms 10, so that the energy consumption is minimized to achieve the required residual moisture of the textile web 1. The respective operating states are dependent on the quality and the input moisture of the textile web, so that empirical values can be entered, for example via a control panel of the dryer 100, which control values are necessary for conditioning the individual dryer rooms 10. These values depend, for example, on the quality, the density, the weight per unit area and the thickness of the textile web 10, wherein preferably the input moisture and initial moisture content of the textile web 10 are taken into account as an input for programming the controller 17 and for running a corresponding dryer program of the dryer 100 become.
