Abstract

A steam generator (3) and nozzle unit treat the material; an extraction unit (5) and a suction pump (10) remove the surplus steam. In novel design, the steam generator is connected to a heat exchanger (13) in thermal contact with the extraction unit. The water supply (12) passes first through the heat exchanger and then through the steam generator, which is in thermal contact with the line (6, 9) from the extraction unit. The heat exchanger follows the suction pump. The heat exchanger is alternatively arranged between the extraction unit and the suction pump. In a further variant, the heat exchanger is directly associated with the extraction unit. The extraction unit is located inside a rotating, steam-permeable drum (4). Optionally, the heat exchanger is also arranged inside the drum.

Description

Die Erfindung betrifft eine Vorrichtung zur Beaufschlagung von Stoffen mittels heißen Gasen, vorzugsweise Wasserdampf, gemäß dem Oberbegriff von Anspruch 1.The The invention relates to a device for applying substances by means of hot gases, preferably water vapor, according to the Preamble of claim 1.

Aus der EP 1 553 222 A1 ist eine Einrichtung zur Beaufschlagung einer Vliesstoffbahn mittels überhitzten Dampf bekannt. Die Beaufschlagung erfolgt über einen Hohlkörper, der sich über die Breite der zu behandelnden Bahn erstreckt. An dessen Unterseite weist der mit überhitzten Dampf beaufschlagbare Hohlkörper eine Vielzahl Austrittsdüsen auf, aus denen heißer Dampf auf die in dichtem Abstand unter dem Körper hindurch geführten Bahn gerichtet wird.From the EP 1 553 222 A1 a device for applying a nonwoven web by means of superheated steam is known. The application is made via a hollow body which extends over the width of the web to be treated. On the underside of which can be acted upon by superheated steam hollow body to a plurality of outlet nozzles, from which hot steam is directed to the closely spaced below the body guided path.

Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der gattungsgemäßen Art zu verbessern.task It is the object of the present invention to provide a device of the generic type Kind of improving.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Vorrichtungsanspruches. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den jeweiligen Unteransprüchen.Solved This object is achieved by the characterizing features of the device claim. Advantageous developments of the invention will become apparent from the respective subclaims.

Gemäß der Erfindung ist vorgesehen, dass ein Wärmetauscher die überschüssige Energie des abgesaugten Dampfes zurückgewinnt und diese der Dampfaufbereitung zugeschlagen wird. Vorzugsweise ist hierbei vorgesehen, dass der Zulauf des Dampferzeugers einem Wärmetauscher, welcher in thermischen Kontakt mit einer der Absaugung (nachgeordneten Leitung steht, vorgeordnet ist. Mittels dem Wärmetauscher wird das dem Dampferzeuger zugeführte Frischwasser vorgewärmt. Je nach Maschinenkonfiguration kann der Wärmetauscher hierbei direkt in der Saugtrommel, der Absaugleitung der Saugtrommel nach- und dem Konden satabscheider vorgeordnet oder dem Kondensatabscheider nebst Saugpumpe nachgeordnet sein.According to the Invention is provided that a heat exchanger, the excess Energy of extracted steam recovers and this the steam treatment is added. Preferably, this is provided that the inlet of the steam generator to a heat exchanger, which in thermal contact with one of the suction (downstream Leadership is, upstream. By means of the heat exchanger The preheated to the steam generator fresh water is preheated. Depending on the machine configuration, the heat exchanger can do this directly in the suction drum, the suction line of the suction drum and the Konden satabscheider upstream or the Kondensatabscheider downstream of the suction pump.

Des Weiteren erfolgt die Erläuterung eines Ausführungsbeispieles anhand der Zeichnungen.Of Further, the explanation of an embodiment is given based on the drawings.

1 zeigt eine Dampfdüseneinheit 1, welche über eine Leitung von einem Überhitzer 2 mit überhitztem Dampf versorgt wird. Der Dampf wird durch einen der Überhitzereinheit vorgeordneten Dampferzeuger 3 bereitgestellt. 1 shows a steam nozzle unit 1 which is via a pipe from a superheater 2 supplied with superheated steam. The steam is passed through a steam generator upstream of the superheater unit 3 provided.

Mittels der Dampfdüseneinheit 1 erfolgt die Dampfbeaufschlagung eines in den 1 und 2 nicht dargestellten Stoffes, der während dieser Dampfbeaufschlagung von einer dampfdurchlässigen Trommel 4 (Siebtrommel) getragen wird. Im Innern der drehbar gelagerten Trommel 4 ist eine Absaugung (Absaugkammer) 5 angebracht, welche mit einer Absaugleitung 6 mit einem Kondensatabscheider 7 verbunden ist. Die flüssigen Bestandteile des im Kondensatabscheider 7 aufgefangenen Bestandteile des abgesaugten Dampfes (Absaugkammer 5) werden über einen Ablauf 8 entsorgt. Über eine Saugleitung 9 ist die gasförmige Phase des Inhaltes des Kondensatabscheiders 7 mit einer Saugpumpe 10 verbunden. Über eine Ausleitung 11 wird der abgesaugte Dampf entsorgt.By means of the steam nozzle unit 1 the steam is applied in the 1 and 2 Not shown substance, during this steaming of a vapor-permeable drum 4 (Sieve drum) is worn. Inside the rotatably mounted drum 4 is a suction (suction chamber) 5 attached, which with a suction line 6 with a condensate separator 7 connected is. The liquid components of the condensate separator 7 Trapped components of the extracted vapor (suction chamber 5 ) are going through a process 8th disposed of. Via a suction line 9 is the gaseous phase of the contents of the condensate separator 7 with a suction pump 10 connected. About a diversion 11 the extracted steam is disposed of.

Der Zulauf 12 (Frischwasser) für den Dampferzeuger 3 ist einem Wärmetauscher 13 vorgeordnet, der thermisch eng mit der Ausleitung 11 der Saugpumpe 10 gekoppelt ist. Mittels der thermischen Energie des durch die Pumpe 10 abgesaugten Dampfes wird so das Frischwasser des Zulaufes 12 vorgewärmt und mit entsprechender Temperatur dem Dampferzeuger 3 zugeführt. Der Energiebedarf des Dampferzeugers reduziert sich so entsprechend der Vorwärmung des zugeführten Frischwassers.The feed 12 (Fresh water) for the steam generator 3 is a heat exchanger 13 upstream, the thermally tight with the discharge 11 the suction pump 10 is coupled. By means of the thermal energy of the pump 10 extracted steam is so the fresh water of the inlet 12 preheated and with appropriate temperature to the steam generator 3 fed. The energy demand of the steam generator is reduced in accordance with the preheating of the fresh water supplied.

Bei der Ausführung nach 2 weisen die Komponenten mit den Bezugszeichen 1–11 die gleiche Bezeichnung und Funktion wie bei dem Beispiel nach 1 auf. Im Unterschied hierzu ist der Wärmetauscher 13A mit dem Zulauf 12A für Frischwasser thermisch mit der Absaugleitung 6 zwischen Absaugkammer 5 und Kondensatabscheider 7 gekoppelt. Hierdurch läßt sich das Frischwasser des Zulaufes 12A auf eine höhere Temperatur verbringen – die Energieeinsparung des Dampferzeugers ist entsprechend höher.In the execution after 2 have the components with the reference numerals 1 - 11 the same name and function as in the example below 1 on. In contrast, the heat exchanger 13A with the feed 12A for fresh water thermally with the suction line 6 between suction chamber 5 and condensate separator 7 coupled. This allows the fresh water of the inlet 12A spend on a higher temperature - the energy savings of the steam generator is correspondingly higher.

Gemäß einer nicht dargestellten Ausführungsform der Erfindung ist der Wärmetauscher zur Aufwärmung des Frischwassers direkt in der Trommel 4 integriert. Durch die dort herrschenden hohen Temperaturen ist der Grad der Energierückgewinnung entsprechend höher.According to an embodiment of the invention, not shown, the heat exchanger for heating the fresh water directly in the drum 4 integrated. Due to the prevailing high temperatures, the degree of energy recovery is correspondingly higher.
