Description
Die Erfindung betrifft ein Verfahren zum Behandeln einer Materialbahn gemäß dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for treating a material web according to the preamble of
Mithilfe eines solchen Verfahrens werden Materialbahnen aus beispielsweise Papier, Kunststoff, Holz oder Metall behandelt, beispielsweise getrocknet oder gereinigt, die mit einer Geschwindigkeit von z.B. 5 m/s fortschreiten.By means of such a method, webs of, for example, paper, plastic, wood or metal are treated, for example dried or cleaned, which are dried at a speed of e.g. 5 m / s progress.
Das beispielsweise zur Trocknung eingesetzte gasförmige Medium, üblicherweise erwärmte Luft, strömt als Luftvorhang aus mindestens einer Schlitzdüse, die bis zu 2,5 m lang sein kann. Dabei bildet sich ein Freistrahl aus, der bei Vernachlässigung eines geringen Einflusses der Bahnbewegung rechtwinklig auf die Materialbahn auftrifft. Danach teilt sich der Strahl auf und wird nach beiden Seiten hin, d.h., in Fortschreitrichtung und entgegengesetzt abgeführt und abgesaugt. Der maximale Wärmeübergang auf die Materialbahn und damit die größte Trockenleistung liegen im sogenannten Staupunkt vor, an der Stelle, an der der Strahl auf die Materialbahn trifft und aufgeteilt wird.The gaseous medium used for drying, for example, usually heated air, flows as an air curtain from at least one slot nozzle, which can be up to 2.5 m long. In the process, a free jet is formed, which impinges on the material web at right angles, neglecting a slight influence of the web movement. Thereafter, the jet splits and is discharged toward both sides, that is, in the advancing direction and opposite, and exhausted. The maximum heat transfer to the material web and thus the greatest drying capacity are in the so-called stagnation point, at the point where the beam meets the material web and is divided.
Allerdings kommt es beim Trocknungsvorgang häufig zu unerwünschten instationären Effekten im Sinne eines chaotischen Strömungsverhaltens, beispielsweise wenn die Strahlen benachbarter Düsen sich gegenseitig beeinflussen oder aufgrund der Düsengeometrie in sich instabil sind.However, unwanted unsteady effects in the sense of a chaotic flow behavior frequently occur during the drying process, for example when the jets of adjacent nozzles influence one another or are unstable due to the nozzle geometry.
Z. B. kann ein Flattern der Materialbahn angeregt und/oder deren Oberfläche geschädigt werden. Die bekannten, bis zu 5 mm breiten Schlitzdüsen, aus denen das Medium mit einer Geschwindigkeit von bis zu 100 m/s austritt, weisen einen parallelen Düsenspalt auf, bei dem die den Schlitz begrenzenden Wände in Strömungsrichtung gleichgerichtet verlaufen.For example, fluttering of the material web can be excited and / or its surface damaged. The known, up to 5 mm wide slot nozzles, from which the medium emerges at a speed of up to 100 m / s, have a parallel nozzle gap, in which the walls delimiting the slot are rectified in the flow direction.
Das geschilderte Strömungsverhalten mit den angedeuteten Problemen führt vielfach zu einer Unterbrechung des Betriebsablaufs, zumindest jedoch zu einer Einschränkung des Trocknungsergebnisses und damit der Qualität der zu trocknenden Materialbahn.The described flow behavior with the indicated problems often leads to an interruption of the operation, but at least to a limitation of the drying result and thus the quality of the material to be dried web.
Das besagte Flattern der Materialbahn kann zu deren Reißen führen und damit zu einer Unterbrechung des Produktionsablaufs. Dies ist naturgemäß mit erheblichen Kosten verbunden, sowohl resultierend aus den Maschinenstillstandszeiten wie auch aus den Materialverlusten.The said fluttering of the web can lead to their tearing and thus to an interruption of the production process. This is naturally associated with considerable costs, both as a result of the machine downtime as well as from the material losses.
Die zum Trocknen der Materialbahn beschriebenen Probleme ergeben sich sinngemäß auch bei anderen Behandlungen, z.B. einer Reinigung der Oberfläche der Materialbahn.The problems described for drying the web of material also apply mutatis mutandis to other treatments, e.g. a cleaning of the surface of the material web.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art so weiterzuentwickeln, dass seine Wirksamkeit verbessert und seine Betriebssicherheit erhöht wird.The invention has for its object to further develop a method of the generic type so that its effectiveness is improved and its reliability is increased.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie durch eine Vorrichtung zur Durchführung des Verfahrens gelöst.This object is achieved by a method having the features of
Durch eine spezielle Formgebung des Düsenschlitzes trifft das Medium, gemäß der Erfindung, unter einem Winkel < 90° auf die Materialbahn auf und wird überdies in einen Vordrall versetzt.By means of a special shaping of the nozzle slot, the medium, according to the invention, strikes the material web at an angle <90 ° and, moreover, is set in a pre-twist.
Insbesondere zu erwähnen ist dabei die wesentliche Verbesserung des Wärmeübergangs vom Medium zur Materialbahn, einhergehend mit einer Optimierung der Behandlungsleistung.To mention in particular is the substantial improvement of the heat transfer from the medium to the web, along with an optimization of the treatment performance.
Überdies wird die Prozessstabilität erhöht, d.h., die zum Stand der Technik beschriebenen nachteiligen Einflüsse auf die Materialbahn selbst hinsichtlich einer Oberflächenbeschädigung, die zu einem Reißen der Bahn führen kann, sind praktisch ausgeschlossen.Moreover, the process stability is increased, that is, the disadvantageous influences on the material web itself described with respect to a prior art Surface damage which can lead to cracking of the web is virtually eliminated.
Hieraus ergibt sich eine durchaus bemerkenswerte Senkung der Betriebskosten, insbesondere aber auch eine verbesserte Produktionssicherheit.This results in a quite remarkable reduction in operating costs, but in particular also improved production reliability.
Nach einer vorteilhaften Weiterbildung der Vorrichtung zur Durchführung des Verfahrens sind die sich gegenüberliegenden, den Schlitz der Düse begrenzenden Wandungen zumindest im Querschnitt wellenförmig ausgeprägt, wobei sich der Schlitz zum Austritt hin verjüngt.According to an advantageous development of the device for carrying out the method, the opposing walls delimiting the slot of the nozzle are undulating, at least in cross-section, with the slot tapering towards the outlet.
Dies bewirkt eine Verbesserung des Wärmeübergangs und damit der Behandlungsleistung, wobei durch diese Formgebung die Grenzschicht des Strahles in Schwingungen versetzt wird.This causes an improvement of the heat transfer and thus the treatment performance, whereby the boundary layer of the beam is set into vibration by this shaping.
Ein weiterer Gedanke sieht vor, den Schlitz zur Oberfläche der bewegten Materialbahn schräg zu stellen.Another idea is to make the slot oblique to the surface of the moving web.
Hierdurch wird im Wesentlichen der Einfluss der Durchlaufgeschwindigkeit, die ansonsten zu einer Strahlablenkung führt, kompensiert, mit der Folge, dass ein Staupunktdruckverlust reduziert und der Behandlungsprozess insgesamt im Vergleich zum rechtwinklig ausgerichteten Spalt nach dem Stand der Technik stabiler ausgeführt wird.This substantially compensates for the influence of the flow rate, which otherwise results in jet deflection, with the result that stagnation point pressure loss is reduced and the overall treatment process is made more stable compared to the prior art right-angled gap.
Das schräge Auftreffen des Strahles auf die Materialbahn führt zu einer strömungstechnischen Stabilisierung des Behandlungsprozesses, vor allem resultierend daraus, dass das weitere Strömungsverhalten nach dem Auftreffen und nach der Strahlaufteilung eindeutiger vorbestimmbar ist als bei einem rechtwinklig ausgerichteten Spalt.The oblique impact of the beam on the material web leads to a fluidic stabilization of the treatment process, especially as a result of the fact that the further flow behavior after impingement and after the beam splitting is unambiguously predeterminable than in a right-angled gap.
Mit einer vergleichbaren Wirkung stellt sich die Ausbildung des Spaltes bzw. dessen sich gegenüberliegenden Wandungen als im Querschnitt kreisbogenförmig dar, durch die Druckverluste gesenkt und die Prozessstabilität ebenfalls erhöht wird.With a comparable effect, the formation of the gap or its opposing walls is circular arc in cross-section, lowered by the pressure losses and the process stability is also increased.
Die kreisbogenförmige Kontur im Sinne eines konkaven/konvexen Verlaufs prägt einen Vordrall des Mediums, durch den der Leistungsbedarf eines angeschlossenen Aggregats zur Erzeugung eines Mediumdrucks, verringert, also optimiert wird.The circular-arc-shaped contour in the sense of a concave / convex profile characterizes a Vordrall of the medium, through which the power requirement of a connected unit for generating a medium pressure, reduced, that is optimized.
Eine weitere Ausführungsvariante einer Schlitzdüse gibt eine einseitig überstehende, gegenüber der zugeordneten Wandung des Schlitzes in Durchlaufrichtung der Materialbahn oder entgegengesetzt geringfügig abgewinkelte Leitkante vor, die bei den Schlitzen zum Einsatz kommt, deren Konfiguration zuvor beschrieben ist.A further embodiment variant of a slot nozzle provides a guide edge projecting on one side and opposite the associated wall of the slot in the direction of passage of the material web or oppositely angled leading edge, which is used in the slots whose configuration has been described above.
Die einseitig in Bezug auf den Mediumaustritt aus der Schlitzdüse verlängerte Leitkante nutzt dabei den sogenannten Coandä-Effekt, bei dem sich eine Strömung an eine Fläche anlegt und dieser auch dann folgt, wenn sie nicht senkrecht nach unten verläuft. In einem Fall ist der Schlitz selbst leicht rückwärts geneigt, die Leitkante hingegen vorwärts.The leading edge, which is extended on one side in relation to the medium exit from the slot nozzle, uses the so-called Coanda effect, in which a flow is applied to a surface and also follows this, if it does not run vertically downwards. In one case, the slot itself is slightly inclined backwards, the leading edge, however, forward.
Dadurch wird ein Drall erzeugt, vergleichbar dem, wie er bei der zuvor beschriebenen Ausführung eines kreisbogenförmigen Spaltes beschrieben ist und bei der die Strömung stabilisiert und ein Druckverlust im Staupunkt signifikant reduziert ist.As a result, a swirl is generated, comparable to that described in the previously described embodiment of a circular-arc gap, in which the flow is stabilized and a pressure loss at the stagnation point is significantly reduced.
Nach einem weiteren Gedanken der Erfindung ist vorgesehen, einen bevorzugt im Querschnitt tropfenförmig ausgebildeten Störkörper im Austrittsbereich des Mediumstroms aus der Schlitzdüse zu positionieren, wobei nach einer Variante der Schlitz als Diffusor ausgebildet ist, in den der Störkörper hineinragt. Diese konstruktive Lösung gestattet es, über eine Lageverstellung des Störkörpers den Volumenstrom des Mediums gezielt zu steuern.According to a further aspect of the invention, it is provided to position a disruptive body, which is preferably drop-shaped in cross-section, out of the slot nozzle in the exit region of the medium flow, wherein, according to a variant, the slot is designed as a diffuser into which the interfering body protrudes. This design solution makes it possible to selectively control the volume flow of the medium via a positional adjustment of the bluff body.
Eine andere Konzeption, bei der ein Störkörper zum Einsatz kommt, sieht den Schlitz als scharfkantig endend vor, vor dem der Störkörper installiert ist, so dass der aus der Schlitzdüse austretende Luftstrom in zwei Hälften aufgeteilt wird, die getrennt auf die Materialbahn auftreffen.Another concept, in which a bluff body is used, provides the slot as a sharp-edged ending, in front of which the bluff body is installed, so that the emerging from the slot nozzle air flow is divided into two halves, which impinge separately on the web.
Neben einer verbesserten Behandlungsleistung erzielt diese Variante auch ein im Vergleich zu einem Schlitz ohne Störkörper stabileres Strömungsverhalten.In addition to an improved treatment performance, this variant also achieves a more stable flow behavior compared to a slot without a disruptive body.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.
