Definitions
- the invention relates to a dryer for a textile web according to the preamble of claim 1, and a method for drying a textile web.
- a textile web is fed to the dryer by looping around the drum to a large extent of the circumference and then removed from the dryer chamber again.
- the fresh air is supplied through this opening, which is heated within the dryer chamber and mixed with the circulating air, so that they can absorb the highest possible proportion of moisture.
- the mixture of circulating air and fresh air flows through the web, at least partially absorbs the moisture of the web and is discharged through the interior of the drum again. From this volume flow, a partial volume flow is removed as exhaust air.
- the moist exhaust air is discharged through channels above the drums, which requires a complex and expensive seal due to the rotating drums and is maintenance-intensive.
- supply lines or channels for fresh air have been subsequently added to the dryer chamber, which can for example be coupled to a heat exchanger for heating the fresh air.
- a previously described dryer is in the DE 102009016019 A1 disclosed.
- the air circulation of the fresh air takes place at right angles to the withdrawal direction of the moist air, that is perpendicular to the drum axis, whereby the air circulation is disturbed within the dryer chamber.
- Another disadvantage is due to lack of space, the often expensive conversion, in which the fresh air duct can not be coupled to a heat exchanger. Since the dryers are very dense in a number of different process engineering aggregates that treat the textile web one after the other, there is often a lack of space to retrofit a fresh air duct between the units.
- the DE 1729499 A1 discloses a screen drum dryer with arranged on the front sides of the screening drums intermediate chambers. Fresh air is supplied to these intermediate chambers and mixed with the drying air. Part of the exhaust air is discharged via the fan room.
- the intermediate chamber is firmly integrated in the dryer housing and can not be retrofitted with a heat exchanger.
- the dryer for a textile web comprises a dryer room with a plurality of drums in the dryer drums arranged behind one another, which are at least partially wrapped by the web, wherein the web of heated drying air is flowed through, which is discharged through an interior of the drums ,
- the dryer a Additional chamber which is arranged on the dryer room and is connected via frontal openings of the drums with the dryer room.
- the connections for the fresh air and the exhaust air to the dryer so that the air flow for the drying process in the dryer room 2 and within the drum is not disturbed.
- the drying air relaxes, so that their flow rate reduces as it exits the drum by a multiple.
- the exhaust air is withdrawn with the least impact on the drying process.
- the fresh air can be sucked in freely by the negative pressure in the additional chamber and directed into the heating and fan room.
- the invention provides to arrange the additional chamber between an end face of the dryer and a heating and fan room.
- the removal of the exhaust air from the drying air in the additional chamber is most optimal, since the drying air has the lowest energy level here.
- the energy loss through the exhaust air is the lowest.
- the clearly defined interface allows the use of heat recovery under optimal conditions. With this, the energy balance can be further improved.
- the fresh air mixes with the drying air.
- means for heating the fresh air and drying air are arranged within the heating and fan room, the heated drying air has only a short way to the dryer room on which it does not cool.
- the fresh and exhaust air flowing in the additional chamber can be separated from one another by means for segmentation.
- the additional chamber can be segmented analogously to the number of drums.
- the individual segments can be partitioned off from one another by walls so that there is no exchange of air between the segments.
- a distribution of the exhaust air or the fresh air can be generated in several segments. This can also be done via baffles.
- the arrangement of the fans to the heating and fan room to circulate the drying air has the advantage that the dryer can be built relatively compact.
- the ports may be streamlined to minimize flow losses.
- the inventive method for drying a textile web is characterized by the steps that drying air is heated and passed into a dryer room in which a web at least partially wraps around at least one arranged within the dryer chamber drum, wherein the heated drying air flows through the web and an interior the drum is discharged, wherein fresh air fed to a separate additional chamber and exhaust air is discharged through the additional chamber.
- the result is a circulation system in which the drying air withdrawn a partial mass flow of exhaust air and a partial mass flow of fresh air is supplied.
- the exhaust air is discharged at the point from the drying air at which the drying air has the lowest energy level, namely in the additional chamber.
- a dryer 1 is shown in the form of a row dryer.
- three drums 3a, 3b, 3c are arranged one behind the other and with their axes 4a, 4b, 4c in a row.
- a web 5 is guided via an inlet 6 into the dryer room 2 into it. Via a guide roller 7, the web 5 is guided first below the first drum 3a, then above the second drum 3b and then below the third drum 3c. Via a guide roller 8, the web 5 is led out through an outlet 9 from the dryer room 2.
- the web 5 is flowed through with heated drying air. The drying air absorbs the moisture of the web 5 and is sucked off through the interior of the drums 3a to 3c.
- an additional chamber 10 is arranged on the dryer chamber 2, into which the channel 12 for the fresh air 11 and the channel 14 for the exhaust air 13 open.
- the additional chamber 10 is completely separate and constructed separately from the dryer room 2.
- the dryer room 2 is connected to air ducts above and below the drums 3a - 3c with the heating and fan room 22.
- the additional chamber 10 is connected via the frontal opening of the drums 3a - 3c with the dryer room 2.
- FIG. 2 is the dryer 1 from the FIG. 1 equipped with an optional heat recovery.
- the same parts have the same reference numerals.
- the heat exchanger 17 is connected simultaneously with the channel 12, so that the fresh air 11, before it flows into the auxiliary chamber 10, has already experienced a temperature increase by the heat exchanger 17. With this optional retrofittable solution, the thermal efficiency of the dryer 1 can be further increased.
- the fresh air 11 does not flow directly into the dryer 1, but only into the additional chamber 10, in which further heating takes place by mixing with the drying air after the flow through the web 5.
- this mixing of the fresh air with the drying air was carried out before the flow through the web 5, whereby the temperature of the drying air is influenced before the web 5.
- the utilization of the temperature difference between the exhaust air 13 and fresh air 11 is sufficient to further increase the thermal efficiency of the dryer 1.
- FIG. 3 shows a side section through a dryer 1.
- the fans 19a - 19c, which suck the moisture-saturated drying air from the drums 3a - 3c are flanged to the heating and fan room 22 and connected via connections 20a - 20c and adapters with the additional chamber 10. Opposite the drums 3a -3c are also connected via connections with the auxiliary chamber 10.
- the drying air flows from the drums 3a-3c into the auxiliary chamber 10 and from the additional chamber 10 via the ports 20a-20c into the intake cross-section of the respective fan 19a-19c.
- the exhaust air from the additional chamber 10 via a channel 14 which is arranged on the front side, removed (see FIG. 1 and 2 ).
- a fan 15 provides the necessary air flow.
- the supply of fresh air takes place in the region of the drum 3 c via the additional chamber 10, to which the channel 12 is connected at the end face.

- heating elements 21 may be arranged in the form of heat exchangers, one or more gas heaters or electric heaters, which heat the discharged drying air 11 including the fresh air to the drying temperature.
- FIG. 4 shows a rear view of the dryer 1, in which the heating and fan room 22 has been hidden.
- the openings of the drums 3a - 3c can be seen, via which the drums 3a - 3c is connected by means of connections with the additional chamber 10.
- the fresh air 11 is introduced via a channel 12 into the additional chamber 10.
- separating plates 23 are arranged in the form of perforated plates, which segment the additional chamber 10, so that the distribution of the fresh air to the individual fans 19a - 19c can be influenced. It is also possible to influence the distribution of the fresh air within the auxiliary chamber 10 via guide plates, not shown, for example, to separate from the exhaust air.

Description
Die Erfindung betrifft einen Trockner für eine textile Warenbahn nach dem Oberbegriff von Anspruch 1, sowie ein Verfahren zum Trocknen einer textilen Warenbahn.The invention relates to a dryer for a textile web according to the preamble of
Zur Trocknung von textilen Warenbahnen sind Trockner bekannt, bei denen in einem Gehäuse eine oder mehrere Trommeln angeordnet sind. Über eine Öffnung in der Trocknerkammer wird eine textile Warenbahn dem Trockner zugeführt, indem sie die Trommel zu einem Großteil des Umfanges umschlingt und dann aus der Trocknerkammer wieder abgeführt wird. Üblicherweise wird über diese Öffnung auch die Frischluft zugeführt, die innerhalb der Trocknerkammer erhitzt und mit der Umluft vermischt wird, damit sie einen möglichst hohen Anteil an Feuchtigkeit aufnehmen kann. Bei der Umschlingung der Trommel strömt das Gemisch aus Umluft und Frischluft durch die Warenbahn, nimmt zumindest teilweise die Feuchtigkeit der Warenbahn auf und wird über den Innenraum der Trommel wieder abgeführt. Aus diesem Volumenstrom wird ein Teilvolumenstrom als Abluft abgeführt. Dabei wird die feuchte Abluft über Kanäle oberhalb der Trommeln abgeführt, was aufgrund der rotierenden Trommeln eine aufwendige und teure Abdichtung erfordert und wartungsintensiv ist. Um den Sogeffekt aus der Umgebung des Trockners zu vermeiden, sind nachträglich an der Trocknerkammer Zuführleitungen bzw. Kanäle für Frischluft angebaut worden, die beispielsweise mit einem Wärmetauscher zur Erwärmung der Frischluft gekoppelt werden können.For drying textile webs dryer are known in which one or more drums are arranged in a housing. Through an opening in the dryer chamber, a textile web is fed to the dryer by looping around the drum to a large extent of the circumference and then removed from the dryer chamber again. Usually, the fresh air is supplied through this opening, which is heated within the dryer chamber and mixed with the circulating air, so that they can absorb the highest possible proportion of moisture. During the winding of the drum, the mixture of circulating air and fresh air flows through the web, at least partially absorbs the moisture of the web and is discharged through the interior of the drum again. From this volume flow, a partial volume flow is removed as exhaust air. The moist exhaust air is discharged through channels above the drums, which requires a complex and expensive seal due to the rotating drums and is maintenance-intensive. In order to avoid the suction effect from the environment of the dryer, supply lines or channels for fresh air have been subsequently added to the dryer chamber, which can for example be coupled to a heat exchanger for heating the fresh air.

Die
Es ist Aufgabe der Erfindung einen Trockner für eine textile Warenbahn zu schaffen, bei dem strömungsgünstig eine Abluft- und Frischluftführung erfolgen kann, bei der auch gegebenenfalls nachträglich ein Wärmetauscher installierbar ist.It is an object of the invention to provide a dryer for a textile web in which aerodynamically an exhaust and fresh air can be done, in which also optionally a heat exchanger can be installed later.
Die Erfindung löst die gestellte Aufgabe durch die Lehre nach Anspruch 1, und 13; weitere vorteilhafte Ausgestaltungsmerkmale der Erfindung sind durch die Unteransprüche gekennzeichnet.The invention solves the problem by the teaching of
Gemäß der technischen Lehre nach Anspruch 1 umfasst der Trockner für eine textile Warenbahn einen Trocknerraum mit mehreren im Trocknerraum hintereinander angeordneten Trommeln, die von der Warenbahn zumindest teilweise umschlungen werden, wobei die Warenbahn von erwärmter Trocknungsluft durchströmt wird, die über einen Innenraum der Trommeln abgeführt wird. Erfindungsgemäß ist vorgesehen, dass der Trockner eine Zusatzkammer aufweist, die an dem Trocknerraum angeordnet ist und über stirnseitige Öffnungen der Trommeln mit dem Trocknerraum verbunden ist.According to the technical teaching of
Mit den Merkmalen der Erfindung ist es möglich, die Anschlüsse für die Frischluft und die Abluft so an dem Trockner anzuordnen, dass die Luftströmung für den Trocknungsprozess im Trocknerraum 2 und innerhalb der Trommel nicht gestört wird. Durch die Zusatzkammer entspannt sich die Trocknungsluft, so dass sich deren Strömungsgeschwindigkeit beim Austritt aus der Trommel um ein vielfaches reduziert. Aus der Zusatzkammer wird die Abluft mit dem geringsten Einfluss auf den Trocknungsprozess entzogen. Weiterhin kann durch den Unterdruck in der Zusatzkammer die Frischluft frei angesaugt und in den Heizungs- und Ventilatorraum geleitet werden.With the features of the invention, it is possible to arrange the connections for the fresh air and the exhaust air to the dryer so that the air flow for the drying process in the
In vorteilhafter Ausgestaltung sieht die Erfindung vor, die Zusatzkammer zwischen einer Stirnseite des Trockners und einem Heizungs- und Ventilatorraum anzuordnen. Aus energetischen Gründen ist die Entnahme der Abluft aus der Trocknungsluft in der Zusatzkammer am optimalsten, da hier die Trocknungsluft das niedrigste Energieniveau hat. Somit ist der Energieverlust durch die Abluft am geringsten. Es ergibt sich eine für den Trocknungsprozess strömungsgünstige Lösung, die unabhängig vom Platzangebot zwischen den nacheinander angeordneten Aggregaten angeordnet werden kann. Zusätzlich erlaubt die eindeutig definierte Schnittstelle die Verwendung einer Wärmerückgewinnung unter optimalen Bedingungen. Mit dieser kann die Energiebilanz weiter verbessert werden.In an advantageous embodiment, the invention provides to arrange the additional chamber between an end face of the dryer and a heating and fan room. For energetic reasons, the removal of the exhaust air from the drying air in the additional chamber is most optimal, since the drying air has the lowest energy level here. Thus, the energy loss through the exhaust air is the lowest. This results in a flow-favorable solution for the drying process, which can be arranged independently of the available space between the successively arranged units. In addition, the clearly defined interface allows the use of heat recovery under optimal conditions. With this, the energy balance can be further improved.
Innerhalb der Zusatzkammer vermischt sich die Frischluft mit der Trocknungsluft. Dadurch, dass innerhalb des Heizungs- und Ventilatorraumes Mittel zum Erwärmen der Frischluft und Trocknungsluft angeordnet sind, hat die erwärmte Trocknungsluft nur einen kurzen Weg bis zum Trocknerraum, auf dem sie nicht abkühlt.Within the additional chamber, the fresh air mixes with the drying air. The fact that means for heating the fresh air and drying air are arranged within the heating and fan room, the heated drying air has only a short way to the dryer room on which it does not cool.
Eine energieeffiziente Verbesserung wird erreicht, in dem die Mittel als Wärmetauscher ausgebildet sind, wobei die Wärmetauscher die Abluft aus der Zusatzkammer nutzen, um die Frischluft und Trocknungsluft zu erwärmen.An energy-efficient improvement is achieved, in which the means are designed as heat exchangers, wherein the heat exchanger, the exhaust air from the Use additional chamber to heat the fresh air and drying air.
Die in der Zusatzkammer strömende Frisch- und Abluft kann durch Mittel zur Segmentierung voneinander getrennt werden. Ebenfalls kann die Zusatzkammer analog zur Anzahl der Trommeln segmentiert werden. Die einzelnen Segmente können durch Wände voneinander abgeschottet werden, damit kein Luftaustausch zwischen den Segmenten entsteht. Über eine teilweise durchlässige Segmentierung, beispielsweise in Form von Lochblechen, kann eine Verteilung der Abluft oder der Frischluft auf mehrere Segmente erzeugt werden. Dies kann ebenfalls über Leitbleche erfolgen.The fresh and exhaust air flowing in the additional chamber can be separated from one another by means for segmentation. Likewise, the additional chamber can be segmented analogously to the number of drums. The individual segments can be partitioned off from one another by walls so that there is no exchange of air between the segments. About a partially transparent segmentation, for example in the form of perforated plates, a distribution of the exhaust air or the fresh air can be generated in several segments. This can also be done via baffles.
Die Anordnung der Ventilatoren an den Heizungs- und Ventilatorraum zur Zirkulation der Trocknungsluft hat den Vorteil, dass der Trockner relativ kompakt gebaut werden kann.The arrangement of the fans to the heating and fan room to circulate the drying air has the advantage that the dryer can be built relatively compact.
Innerhalb der Zusatzkammer sind Anschlüsse angeordnet, durch die die Trocknungsluft aus dem Trocknerraum bzw. den Trommeln mittels der Ventilatoren abgesaugt werden kann. Die Anschlüsse wiederum können strömungsgünstig ausgebildet sein, um die Strömungsverluste zu minimieren.Within the additional chamber connections are arranged, through which the drying air from the dryer room or the drums can be sucked by means of the fans. In turn, the ports may be streamlined to minimize flow losses.
Das erfindungsgemäße Verfahren zum Trocknen einer textilen Warenbahn ist gekennzeichnet durch die Verfahrensschritte, dass Trocknungsluft erwärmt und in einen Trocknerraum geleitet wird, in dem eine Warenbahn zumindest teilweise mindestens eine innerhalb des Trocknerraumes angeordnete Trommel umschlingt, wobei die erwärmte Trocknungsluft die Warenbahn durchströmt und über einen Innenraum der Trommel abgeführt wird, wobei Frischluft einer separaten Zusatzkammer zugeführt und Abluft über die Zusatzkammer abgeführt wird.The inventive method for drying a textile web is characterized by the steps that drying air is heated and passed into a dryer room in which a web at least partially wraps around at least one arranged within the dryer chamber drum, wherein the heated drying air flows through the web and an interior the drum is discharged, wherein fresh air fed to a separate additional chamber and exhaust air is discharged through the additional chamber.
Durch die Zusatzkammer werden die Strömungsverhältnisse innerhalb des Trocknerraumes und der Trommel nicht beeinflusst. Die Abluft reduziert beim Eintritt in die Zusatzkammer deutlich die Strömungsgeschwindigkeit, wohingegen die Frischluft aufgrund des Unterdruckes in der Zusatzkammer frei angesaugt und in den Heizungs- und Ventilatorraum geleitet werden kann.Due to the additional chamber, the flow conditions within the dryer space and the drum are not affected. The exhaust air reduces significantly when entering the additional chamber, the flow rate, whereas the fresh air can be sucked in freely due to the negative pressure in the additional chamber and directed into the heating and fan room.
Es entsteht ein Kreislaufsystem, bei der der Trocknungsluft ein Teilmassenstrom von Abluft entzogen und ein Teilmassenstrom von Frischluft zugeführt wird. Dabei wird die Abluft an der Stelle aus der Trocknungsluft abgeführt, an der die Trocknungsluft das geringste Energieniveau besitzt, nämlich in der Zusatzkammer.The result is a circulation system in which the drying air withdrawn a partial mass flow of exhaust air and a partial mass flow of fresh air is supplied. The exhaust air is discharged at the point from the drying air at which the drying air has the lowest energy level, namely in the additional chamber.

Im Unterschied zum Stand der Technik strömt hierbei die Frischluft 11 nicht direkt in den Trockner 1, sondern erst in die Zusatzkammer 10, in der eine weitere Erwärmung durch eine Mischung mit der Trocknungsluft nach der Durchströmung der Warenbahn 5 stattfindet. In vorherigen Konstruktionen erfolgte diese Durchmischung der Frischluft mit der Trocknungsluft vor der Durchströmung der Warenbahn 5, wodurch die Temperatur der Trocknungsluft vor der Warenbahn 5 beeinflusst wird.
