Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen von Rauchgaszügen einer Kesselanlage mit einem Reinigungsschlauch, der durch einen Zugang in einem Rauchgaszug einführbar ist.The invention relates to a device for cleaning flues of a boiler system with a cleaning hose which can be inserted through an access in a flue.

Darüber hinaus betrifft die Erfindung ein Verfahren zum Reinigen von Rauchgaszügen einer Kesselanlage mit einem Reinigungsschlauch, bei dem der Reinigungsschlauch von einem Schlauchspeicher abgerollt wird und durch eine Öffnung in einen Rauchgaszug eingeführt wird.Moreover, the invention relates to a method for cleaning flues of a boiler system with a cleaning hose, wherein the cleaning hose is unrolled from a hose storage and is introduced through an opening in a flue.

Insbesondere betrifft die Erfindung ein Verfahren zum Reinigen der Leerzüge eines Kessels. Die Leerzüge oder sogenannten Strahlungszüge werden als gasdicht verschweißte Membranwandkonstruktion ausgeführt und dienen in Kesselanlagen als Wärmetauscherflächen. Die im Rauchgas transportierte Flugasche setzt sich teilweise während des Betriebs an den Membranwänden der Leerzüge fest und kann sich im weiteren Verlauf zu harten Anbackungen entwickeln. Die Folge ist ein verminderter Wärmeaustausch über die Membranwände, welcher zum Anstieg der Rauchgastemperatur führt und die daraus resultierende Reduzierung des Wirkungsgrades einer solchen Wärmekraftanlage. Da die in den anhaftenden Verschmutzungen vorhandenen Salze korrosiv mit dem Stahl reagieren, stellt die Reinigung der Membranwände auch einen erhöhten Schutz vor Korrosion dar.In particular, the invention relates to a method for cleaning the Leerzüge a boiler. The Leerzüge or so-called radiation trains are designed as gas-tight welded membrane wall construction and are used in boiler systems as heat exchanger surfaces. The fly ash transported in the flue gas is partly fixed during operation on the membrane walls of the Leerzüge and can develop in the course to hard caking. The result is a reduced heat exchange across the membrane walls, which leads to the rise of the flue gas temperature and the resulting reduction in the efficiency of such a thermal power plant. Since the salts present in the adhering contaminants react corrosively with the steel, the cleaning of the membrane walls also provides increased protection against corrosion.

Durch die regelmäßige Reinigung der verschmutzen Membranwände wird die Rauchgastemperatur in Strahlungszügen bzw. vor dem Eintritt in nachgeschaltete konvektive Heizflächen auf einem akzeptablen Wert gehalten. Dies führt zu einer Erhöhung der Verfügbarkeit der gesamten Anlage.By regularly cleaning the dirty membrane walls, the flue gas temperature in radiation trains or before entry into downstream convective heating surfaces is kept at an acceptable level. This leads to an increase in the availability of the entire system.

Auf herkömmliche Art und Weise wird der Reinigungsschlauch von einem trommelartigen Schlauchspeicher manuell oder motorbetrieben abgerollt und zu einer Öffnung in der Decke der Kesselanlage geführt. Dort wird der Schlauch in eine Öffnung eingeführt, durch die der Schlauch zum Rauchgaszug geführt wird. Dies ist arbeits- und zeitaufwendig.In a conventional manner, the cleaning hose is unrolled by a drum-type hose store manually or motorized and led to an opening in the ceiling of the boiler system. There, the hose is inserted into an opening through which the hose is led to the flue. This is laborious and time consuming.

Als Möglichkeiten einer Schlauchreinigung verweist die DE 10 2010 051 657 A1 auf mechanische Reinigungsmittel, wie zum Beispiel Bürsten, oder Sprühvorrichtungen für Druckluft oder Reinigungsflüssigkeiten. Als bevorzugtes Ausführungsbeispiel wird eine pneumatische Abblasdüse verwendet.As possibilities of a hose cleaning refers the DE 10 2010 051 657 A1 on mechanical cleaning agents, such as brushes, or spraying devices for compressed air or cleaning fluids. As a preferred embodiment, a pneumatic blow-off nozzle is used.

Der Erfindung liegt die Aufgabe zu Grunde, eine gattungsgemäße Vorrichtung dahingehend weiterzuentwickeln, dass es einfacher wird, mit dem Reinigungsschlauch Rauchgaszüge zu reinigen.The invention is based on the object to develop a generic device to the effect that it is easier to clean with the cleaning hose flues.

Diese Aufgabe wird mit einer Vorrichtung mit den Merkmalen des Patentanspruchs 1 gelöst. Das Anblasen des Reinigungsschlauches mit Druckluft ermöglicht es, vom Reinigungsschlauch Staubpartikel abzublasen oder Feuchtigkeit, die von einer Nassreinigung des Schlauchs stammt, zu trocknen.This object is achieved with a device having the features of patent claim 1. Blowing the cleaning hose with compressed air makes it possible to blow off dust particles from the cleaning hose or to dry moisture resulting from wet cleaning of the hose.

Die Kombination einer pneumatischen Trockenreinigung mit einer Nassreinigung ermöglicht es, dass die Schlauchreinigungseinrichtung den Schlauch zunächst mit angesprühtem Wasser reinigt und anschließend durch eine Luftbedüsung trocknet und nachreinigt.The combination of a pneumatic dry cleaning with a wet cleaning makes it possible for the hose cleaning device to first clean the hose with sprayed water and then to dry it by air spraying and to clean it afterwards.

Vorteilhaft ist es, wenn die Vorrichtung ein Reinigungsschlauchfördermodul aufweist, mit dem der Reinigungsschlauch vom Schlauchspeicher in die Schlauchführung, die zwischen der Decke des Kessels und einer Plattform verläuft, schiebbar ist.It is advantageous if the device has a cleaning hose delivery module, with which the cleaning hose from the hose storage into the hose guide, which extends between the ceiling of the boiler and a platform, is pushed.

Wenn die Schlauchführung eine senkrechte und eine waagerechte Richtungskomponente aufweist, kann ein Schlauch nicht nur in der Schlauchführung senkrecht nach unten in den Kessel geschoben werden sondern es können die Eingänge der Schlauchführungen auf einer Linie oder einem Bogen angeordnet sein, während die Öffnungen in der Kesseldecke nicht auf einer Linie oder einem Bogen angeordnet sind.If the hose guide has a vertical and a horizontal direction component, a hose can be pushed not only in the hose guide vertically down into the boiler but it can be the inputs of Hose guides are arranged on a line or a bend, while the openings in the boiler ceiling are not arranged in a line or a curve.

Das Schieben des Reinigungsschlauches ermöglicht es, auch Bögen größer als 30 ° mit einem Biegeradius von mindestens 500 mm für die Schlauchführung einzusetzen. Vorteilhaft ist es, wenn die Schlauchführung auch Bögen von weniger als 45 ° und bevorzugt sogar weniger als 40 ° aufweist. Somit sind auch spitzwinkligere Bögen als bisher möglich.Pushing the cleaning hose makes it possible to also use bends greater than 30 ° with a bending radius of at least 500 mm for the hose guide. It is advantageous if the hose guide also has bends of less than 45 ° and preferably even less than 40 °. Thus, more acute-angled bends are possible than before.

Besonders vorteilhaft ist es, wenn die Schlauchtrommel waagerecht angeordnet ist. Dies ermöglicht es den Schlauchspeicher auch bei begrenzten Platzverhältnissen oberhalb der Plattform anzuordnen.It is particularly advantageous if the hose drum is arranged horizontally. This makes it possible to arrange the hose storage above the platform even in limited space.

Das Reinigungsschlauchfördermodul erlaubt es, mit einer definierten konstanten Geschwindigkeit den Reinigungsschlauch von der Schlauchtrommel abzuziehen und in die Schlauchführung einzuführen, sodass der Schlauch automatisch vom Schlauchspeicher zum Rauchgaszug gefördert werden kann.The cleaning hose delivery module allows the cleaning hose to be removed from the hose reel at a defined constant speed and inserted into the hose guide so that the hose can be conveyed automatically from the hose repository to the flue gas flue.

Vorteilhaft ist es, wenn das Reinigungsschlauchfördermodul unmittelbar vor der Schlauchführung angeordnet ist. Dies ermöglicht es, den flexiblen Reinigungsschlauch mittels des Reinigungsschlauchfördermoduls in die Schlauchführung zuschieben, um ihn dadurch auch durch eine lange rohrförmige Schlauchführung zum Rauchgaszug zu fördern. Insbesondere kann der Schlauch somit in die Schlauchführung hineingeschoben werden, um in der Schlauchführung geführt den Weg bis zur Öffnung und in den Rauchgaszug zu finden. Dies ist insbesondere bei langen Schlauchführungen von Vorteil.It is advantageous if the cleaning hose delivery module is arranged immediately in front of the hose guide. This makes it possible to push the flexible cleaning hose by means of the Reinigungsschlauchfördermoduls in the hose guide to thereby promote him through a long tubular hose guide to the flue. In particular, the hose can thus be pushed into the hose guide to guided in the hose guide to find the way to the opening and in the flue. This is particularly advantageous for long hose guides.

Eine vorteilhafte Ausführungsvariante sieht vor, dass das Reinigungsschlauchfördermodul mittels Federkraft vorgespannte Anpressrollen aufweist. Damit kann der Reinigungsschlauch behutsam und effektiv gefördert werden.An advantageous embodiment provides that the cleaning hose delivery module has prestressed pressure rollers by means of spring force. Thus, the cleaning hose can be conveyed gently and effectively.

Je nachdem, ob der Schlauch noch vollständig auf der Trommel des Schlauchspeichers liegt oder bereits weitgehend abgerollt ist, führt ein Zug am Schlauch mit einer definierten Kraft zu einer unterschiedlichen Abwickelgeschwindigkeit. Es wird daher vorgeschlagen, dass die Geschwindigkeit des vom Reinigungsschlauchfördermodul angetriebenen Reinigungsschlauches über einen Vorschubantrieb geregelt ist.Depending on whether the hose is still completely on the drum of the hose storage or already largely unrolled, a pull on the hose with a defined force to a different unwinding speed. It is therefore proposed that the speed of the cleaning hose driven by the cleaning hose delivery module is controlled by a feed drive.

Um allein durch Schwenken eines Armes, an dem das Reinigungsschlauchfördermodul angeordnet ist, mehrere Zugänge von Schlauchführungen zu erreichen, wird vorgeschlagen, dass die Mehrzahl der Zugänge von Schlauchführungen auf einer Kreisbahn angeordnet ist. Dies ermöglicht es, mit einer zentral positionierten Einheit über einen sich radial erstreckenden Haltearm den Schlauch zu mehreren Schlauchführungen zu fördern, die jeweils zu unterschiedlichen Rauchgaszügen oder unterschiedlichen Orten an der Decke von Rauchgaszügen führen.In order to achieve multiple accesses of hose guides by pivoting an arm on which the cleaning hose delivery module is arranged, it is proposed that the majority of the inlets of hose guides be arranged in a circular path. This makes it possible to promote with a centrally positioned unit via a radially extending arm the hose to several hose guides, each leading to different flues or different locations on the ceiling of flues.

Eine konstruktive Ausgestaltung sieht eine Reinigungsschlauchpositionierungseinrichtung vor, die den Reinigungsschlauch auf einer definierten Bahn zu mehreren Schlauchführungen führt. Dies ermöglicht es, mit der Reinigungsschlauchpositioniereinrichtung den Reinigungsschlauch zu einer Schlauchführung zu bringen und dort anzuhalten, sodass der Schlauch vom Schlauchspeicher abgewickelt und in die Schlauchführung eingeführt werden kann.A constructional embodiment provides a cleaning hose positioning device, which guides the cleaning hose on a defined path to a plurality of hose guides. This makes it possible with the cleaning hose positioning device to bring the cleaning hose to a hose guide and stop there, so that the hose can be unwound from the hose storage and inserted into the hose guide.

Die Bahn der Reinigungsschlauchpositioniereinrichtung liegt vorzugsweise auf einer Kreislinie. Es ist jedoch auch möglich, die Reinigungsschlauchpositioniereinrichtung so auszubilden, dass die Bahn auf einer geraden Linie liegt. Hierzu weist die Reinigungsschlauchpositioniereinrichtung einen Reinigungsschlauchhaltearm auf, der lateral verschiebbar oder schwenkbar ist, um den Reinigungsschlauch entlang mehrerer auf einer Linie angeordneter Schlauchführungen zu positionieren.The path of the cleaning hose positioning device is preferably located on a circular line. However, it is also possible to form the Reinigungsschlauchpositioniereinrichtung so that the web lies on a straight line. For this purpose, the cleaning hose positioning device has a cleaning hose holding arm, which is laterally displaceable or pivotable, in order to position the cleaning hose along a plurality of line guides arranged on a line.

Die Reinigungsschlauchpositioniereinrichtung ist auch unabhängig von den zuvor genannten Merkmalen der Erfindung und insbesondere ohne Reinigungsschlauchfördermodul erfindungswesentlich.The Reinigungsschlauchpositioniereinrichtung is also essential to the invention independently of the aforementioned features of the invention and in particular without Reinigungsschlauchfördermodul.

Eine vorteilhafte Ausführungsvariante sieht vor, dass die Schlaureinigungseinrichtung am Reinigungsschlauchfördermodul befestigt ist und mit der Schlauchführung verbindbar ist. Dies ermöglicht es, eine einzige Schlauchreinigungseinrichtung am Reinigungsschlauchfördermodul vorzusehen und beim Herausziehen des Reinigungsschlauches aus unterschiedlichen Rauchgaszügen jeweils den Reinigungsschlauch mit derselben Schlauchreinigungseinrichtung zu reinigen.An advantageous embodiment provides that the Schlaureinigungseinrichtung is attached to the cleaning hose delivery module and can be connected to the hose guide. This makes it possible to provide a single hose cleaning device on the cleaning hose conveying module and to clean the cleaning hose with the same hose cleaning device when pulling out the cleaning hose from different flue gas flaps.

Die der Erfindung zugrunde liegende Aufgabe wird auch mit einem Verfahren zum Reinigen von Rauchgaszügen einer Kesselanlage mit den Merkmalen des Patentanspruchs 15 gelöst.The object underlying the invention is also achieved with a method for cleaning flues of a boiler plant with the features of claim 15.

Dies ermöglicht es, den Reinigungsschlauch mit einem Reinigungsschlauchfördermodul über längere Strecken in der rohrförmigen Schlauchführung über senkrechte, schräge und sogar fast waagerechte Strecken zu einer Öffnung in einem Rauchgaszug zu führen. Fast waagerecht ist in diesem Fall ein Gefälle von weniger als 20 ° gegenüber der Waagrechten. Das Schieben des Schlauches durch eine rohrförmige Schlauchführung ermöglicht es auch, in schwer zugänglichen Bereichen den Schlauch auf einer definierten Bahn vom Schlauchspeicher zum Rauchgaszug zu fördern. Dabei können die Bewegung des Schlauches und die Reinigung des Schlauches vollautomatisch durchgeführt werden.This makes it possible to guide the cleaning hose with a cleaning hose delivery module over long distances in the tubular hose guide over vertical, oblique and even almost horizontal distances to an opening in a flue. Almost horizontal in this case, a slope of less than 20 ° to the horizontal. Pushing the hose through a tubular hose guide also makes it possible to convey the hose on a defined path from the hose storage to the flue in difficult to access areas. The movement of the hose and the cleaning of the hose can be carried out fully automatically.

Die rohrförmige Schlauchführung wird mit einem Gleitmittel gespült bevor, während oder nachdem der Reinigungsschlauch in die Schlauchführung geschoben wird. Dieses Gleitmittel ist im einfachsten Fall Wasser. Die Gleiteigenschaften des Wassers können jedoch auch durch Tenside oder andere Chemikalien verstärkt werden oder es können auch hydrophobe Substanzen verwendet werden.The tubular tube guide is flushed with a lubricant before, during or after the cleaning tube is pushed into the tube guide. This lubricant is water in the simplest case. However, the slip properties of the water may also be enhanced by surfactants or other chemicals, or hydrophobic substances may be used.

Die Figuren 1 und 2 zeigen schematisch, wie bei einer Vorrichtung 1 zum Reinigen von Rauchgaszügen einer Kesselanlage 2 eine Reinigungsschlauchpositioniereinrichtung 3 einen Reinigungsschlauch 4 zu mehreren Schlauchführungen 5, 6, 7, 8, 9 bzw. 5', 6', 7', 8', 9' führt. Dabei liegen die Schlauchführungen 5 bis 9 auf einer geraden Linie 10, während die Schlauchführungen 5' bis 9' auf einer Kreislinie 11 liegen.The Figures 1 and 2 schematically show how in a device 1 for cleaning flues of a boiler plant 2 a Reinigungsschlauchpositioniereinrichtung 3 a cleaning hose 4 to several hose guides 5, 6, 7, 8, 9 and 5 ', 6', 7 ', 8', 9 'leads , The tube guides 5 to 9 lie on a straight line 10, while the tube guides 5 'to 9' lie on a circular line 11.

Die Reinigungsschlauchpositioniereinrichtung 3 ist dafür längst der Pfeilrichtung des Pfeiles 12 auf einer geraden Bahn verschiebbar, um den Reinigungsschlauch 4 zu den Schlauchführungen 5 bis 9 zu führen. Die Reinigungsschlauchpositioniereinrichtung 3' ist hingegen längst des Pfeiles 13 um einen Punkt 14 schwenkbar, um den Reinigungsschlauch 4' zu den Schlauchführungen 5' bis 9' zu führen.The cleaning hose positioning device 3 has long since the direction of the arrow 12 of the arrow on a straight path slidable to guide the cleaning hose 4 to the hose guides 5 to 9. By contrast, the cleaning hose positioning device 3 'has long been pivotable about a point 14 of the arrow 13 in order to guide the cleaning hose 4' to the hose guides 5 'to 9'.

Die Figur 3 zeigt die Reinigungsschlauchpositioniereinrichtung 3 die mit einem Sockel 15 auf einer Plattform 16 steht. Bei einer linearen Anordnung ist der Sockel mit einer Art Schienensystem verbunden, sodass die Reinigungsschlauchpositioniereinrichtung 3 in einer Achse verfährt. Im Falle einer halbrunden Anordnung der Stutzen 17 der Schlauchführungen 5' bis 9' ist dieser Sockel 15 drehbar gelagert. Die Drehung der Reinigungsschlauchpositioniereinrichtung 3' erfolgt über einen am Rahmen angeflanschten Getriebemotor bis die Position über dem gewünschten Stutzen 17 erreicht ist.The FIG. 3 shows the Reinigungsschlauchpositioniereinrichtung 3 which stands with a base 15 on a platform 16. In a linear arrangement of the base is connected to a kind of rail system, so that the Reinigungsschlauchpositioniereinrichtung 3 moves in an axis. In the case of a semicircular arrangement of the nozzle 17 of the hose guides 5 'to 9', this base 15 is rotatably mounted. The rotation of the Cleaning hose positioning device 3 'via a geared motor flanged to the frame until the position above the desired nozzle 17 is reached.

An der Reinigungsschlauchpositioniereinrichtung 3, 3' ist eine Schlauchtrommel 37 als Schlauchspeicher 18 angeordnet und mittels des Reinigungsschlauchfördermoduls 19 wird der Reinigungsschlauch 4 zu einer Schlauchführung 5 bis 9 geführt.At the cleaning hose positioning device 3, 3 ', a hose reel 37 is arranged as a hose repository 18 and by means of the cleaning hose conveying module 19 the cleaning hose 4 is guided to a hose guide 5 to 9.

Damit der vom Reinigungsschlauchfördermodul 19 angetriebene von der Schlauchtrommel 37 abgerollte Schlauch vor Eintritt in die Schlauchführung 5 bis 9 nicht knickt, ist das Reinigungsschlauchfördermodul 19 unmittelbar vor der Schlauchführung angeordnet.So that the hose, which is driven by the cleaning hose conveying module 19 and does not roll off the hose reel 37, does not buckle before entering the hose guide 5 to 9, the cleaning hose conveying module 19 is arranged directly in front of the hose guide.

Das Reinigungsschlauchfördermodul 19 weist eine Vorschubrolle 20 mit einer umlaufenden Nut 21 auf, in der der Schlauch 4 geführt ist. Der Schlauch 4 kann dabei in der Nut 21 festgehalten werden, sodass eine Umfangskraft der Rolle 20 bei einem Drehen der Rolle 20 sich auf den Schlauch 4 überträgt. Vorteilhaft ist es, wenn mehrere Anpressrollen 22 bis 25 den Schlauch in die Nut 21 drücken.The cleaning hose conveying module 19 has a feed roller 20 with a circumferential groove 21, in which the hose 4 is guided. The tube 4 can be held in the groove 21, so that a circumferential force of the roller 20 upon rotation of the roller 20 transmits to the tube 4. It is advantageous if several pressure rollers 22 to 25 press the tube into the groove 21.

Die Figur 4 zeigt eine Schlauchreinigungseinrichtung 26. Am vorderen Ende des Schlauches 4 ist eine Düse 27 angeordnet, die durch die Schlauchreinigungseinrichtung 26 hindurch und durch den Stutzen 17 in die Schlauchführung 5 geschoben werden kann. Die Düse 27 gelangt dann in die Kesselanlage 2 und dort in den Rauchgaszug 28, um dort Wärmetauscherflächen und Membranwände zu reinigen.The FIG. 4 shows a hose cleaning device 26. At the front end of the hose 4, a nozzle 27 is arranged, which can be pushed through the hose cleaning device 26 and through the nozzle 17 in the hose guide 5. The nozzle 27 then passes into the boiler system 2 and there into the flue 28 to clean there heat exchanger surfaces and membrane walls.

Beim Hereinfahren und Herausziehen der Düse 27 kommt der Schlauch 4 in Berührung mit Rauchgasen. Dies führt dazu, dass der Reinigungsschlauch 4 mit seinem typischen Metallgewebe als schützende Außenhülle eine beträchtliche Menge Flugasche beim Herausziehen aus dem Kesselinneren nach außen transportiert. Dies kann zu Verschmutzungen am Schieber 29, am Stutzen 17 und an der Schlauchtrommel 37 des Schlauchspeichers 18 führen. Auch das Reinigungsschlauchfördermodul 19 wird durch derartige Verschmutzungen beeinträchtigt. Daher werden mit der Schlauchreinigungseinrichtung 26 der Schlauch 4 und gegebenenfalls auch die Düse 27 gereinigt.When driving in and pulling out the nozzle 27, the hose 4 comes into contact with flue gases. As a result, the cleaning hose 4 with its typical metal fabric as a protective outer shell transports a considerable amount of fly ash when it is pulled out of the interior of the boiler. This can lead to contamination on the slide 29, the nozzle 17 and the hose reel 37 of the hose accumulator 18. Also, the cleaning hose delivery module 19 is through such contamination affected. Therefore, with the hose cleaning device 26, the hose 4 and possibly also the nozzle 27 are cleaned.

Als Schlauchreinigungseinrichtung 26 dient ein rohrförmiges Element als Spülrohr 30, an dem ein Gaszugang 31 und ein Flüssigkeitszugang 32 angeordnet sind. Der Gaszugang 31 steht mit einer unter Druck stehenden Gasleitung (nicht gezeigt) in Verbindung, während der Flüssigkeitszugang 32 mit einer Reinigungsflüssigkeitsleitung wie beispielsweise einer Brauchwasserleitung (nicht gezeigt) in Verbindung steht.The hose cleaning device 26 is a tubular element as a flushing pipe 30, to which a gas inlet 31 and a liquid access 32 are arranged. The gas inlet 31 communicates with a pressurized gas line (not shown) while the liquid access 32 communicates with a cleaning fluid line such as a service water line (not shown).

Beim Herausziehen des verschmutzen Schlauches 4 aus der Schlauchführung 5 wird der Schlauch 4 somit zunächst über Düsen 33 mit Reinigungsflüssigkeit besprüht und anschließend mittels einer pneumatischen Schlauchbedüsung getrocknet. Jedes Teil des Schlauches 4 durchfährt somit beim Herausziehen des Schlauches zunächst eine Schlauchbedüsung 34 mit einer Flüssigkeit und anschließend eine pneumatische Schlauchbedüsung 35, um gereinigt das Spülrohr 30 zu verlassen.When pulling out the dirty hose 4 from the hose guide 5, the hose 4 is thus first sprayed through nozzles 33 with cleaning liquid and then dried by means of a pneumatic Schlauchbedüsung. Each part of the tube 4 thus passes when pulling out of the tube first a Schlauchbedüsung 34 with a liquid and then a pneumatic Schlauchbedüsung 35 to leave the flushing pipe 30 cleaned.

Um den Schlauch 4 genau in die Reinigungseinrichtung 26 einzuführen, ist eine Hubzylindereinheit 36 vorgesehen, die zwischen der Reinigungseinrichtung 26 und dem Reinigungsschlauchfördermodul 19 angeordnet ist.In order to introduce the hose 4 exactly into the cleaning device 26, a lifting cylinder unit 36 is provided which is arranged between the cleaning device 26 and the cleaning hose conveying module 19.

Damit für viele Stutzen 17 von Schlauchführungen 5 bis 9 nur eine Schlauchreinigungseinrichtung 26 benötigt wird, ist die Schlauchreinigungseinrichtung 26 am Reinigungsschlauchfördermodul 19 befestigt.So that only a hose cleaning device 26 is required for many nozzles 17 of hose guides 5 to 9, the hose cleaning device 26 is fastened to the cleaning hose conveyor module 19.

Beim Einsatz der Vorrichtung 1 zum Reinigen von Rauchgaszügen 28 wird das Reinigungsmodul mit einem ersten Antriebsmotor der Reinigungsschlauchpositioniereinrichtung 3 über einem Stutzen 17 einer Schlauchführung 5 positioniert. Ein zweiter Motor bewerkstelligt das Auf- und Abrollen des Schlauches. Mittels zweier Kupplungen wird entweder die Vorschubrolle 20 zum Absenken oder die Schlauchtrommel 37 des Schlauchspeichers 18 zum Herausziehen des Schlauches 4 mit dem Antrieb verbunden. Zur Sicherheit gegen selbstständiges Abwickeln des Schlauches wird die Schlauchtrommel 37 über eine Bremse 38 gehalten.When using the device 1 for cleaning flue gas trains 28, the cleaning module is positioned with a first drive motor of the cleaning hose positioning device 3 via a connection 17 of a hose guide 5. A second motor accomplishes the winding and unwinding of the hose. By means of two clutches either the feed roller 20 for lowering or the hose reel 37 of the hose accumulator 18 for pulling out the hose 4 is connected to the drive. For safety against unintentional unwinding of the hose, the hose reel 37 is held by a brake 38.

Wenn die Schlauchreinigungseinrichtung 26 durch einen am Rahmen der Schlauchpositioniereinrichtung 3 angeordneten Getriebemotor über dem gewünschten Stutzen 17 positioniert ist, wird die Schlauchreinigungseinrichtung 26 mittels eines Pneumatikzylinders 36 durch einen Schieber 29 hindurch in den Stutzen 17 abgesenkt. Die hydraulische Schlauchbedüsung 34 und die pneumatische Schlauchbedüsung 35 wirken als Spül- und Trockeneinheit. Durch ihre Positionierung in einem Trichter (nicht gezeigt) des Stutzens 17 ist die Drehbewegung der Reinigungsschlauchpositioniereinrichtung 3 hinreichend arretiert. Eine zusätzliche Fixierung dieser Position ist nicht erforderlich. Dadurch entsteht ein nahezu geschlossenes System, welches das Ausströmen von Rauchgasen aufgrund von beispielsweise Verpuffungen vermindern kann.When the hose cleaning device 26 is positioned above the desired nozzle 17 by a geared motor arranged on the frame of the hose positioning device 3, the hose cleaning device 26 is lowered by means of a pneumatic cylinder 36 through a slide 29 into the nozzle 17. The hydraulic Schlauchbedüsung 34 and the pneumatic Schlauchbedüsung 35 act as a rinsing and drying unit. By their positioning in a funnel (not shown) of the nozzle 17, the rotational movement of the Reinigungsschlauchpositioniereinrichtung 3 is sufficiently locked. An additional fixation of this position is not required. This creates a nearly closed system, which can reduce the outflow of flue gases due to, for example, deflagration.

Durch Schließen einer ersten Kupplung wird nun ein Riemenrad mit einer Antriebswelle verbunden und mit Hilfe des integrierten Reinigungsschlauchfördermoduls 19 wird der Schlauch 4 mit seiner Düse 27 in die Schlauchführung 5 eingeschoben. Dazu pressen die federbelasteten Anpressrollen 22 bis 25 den Schlauch 4 in die Nut 21 der Vorschubrolle 20, sodass diese aufgrund des Reibschlusses mit der Vorschubrolle von der Schlauchtrommel 37 gezogen wird. Der Antrieb der Vorschubrolle 20 erfolgt dabei von einer Antriebswelle über die erste Kupplung, einen Zahnriemen und ein Umlenkgetriebe. Voraussetzung dafür ist, dass sowohl die zweite Kupplung als auch die Bremse offen sind, sodass sich die Schlauchtrommel frei drehen kann.By closing a first clutch, a pulley is now connected to a drive shaft and with the aid of the integrated cleaning hose delivery module 19, the hose 4 is inserted with its nozzle 27 into the hose guide 5. For this purpose, the spring-loaded pressure rollers 22 to 25 press the tube 4 into the groove 21 of the feed roller 20, so that it is pulled by the hose reel 37 due to the frictional engagement with the feed roller. The drive of the feed roller 20 is effected by a drive shaft via the first clutch, a toothed belt and a deflection gear. The prerequisite for this is that both the second clutch and the brake are open so that the hose reel can rotate freely.

Das Reinigungsschlauchfördermodul 19 hat den Vorteil, dass sowohl eine senkrechte als auch eine horizontale Einführung des Schlauches 4 in eine Schlauchführung 5 möglich ist. Darüber hinaus können durch den Einsatz des Reinigungsschlauchfördermoduls Bögen größer 30 ° mit einem Bogenmaß von mindestens 400 bis 500 mm eingesetzt werden, sodass auch bauliche Engstellen oder geringe Platzverhältnisse im Bereich zwischen der Kesseldecke des Kessels 2 und Plattform 16, in dem die Schlauchführungen verlaufen, keine Probleme bereiten.The cleaning hose delivery module 19 has the advantage that both a vertical and a horizontal insertion of the hose 4 in a hose guide 5 is possible. In addition, by using the cleaning hose delivery module, sheets greater than 30 ° with a radian measure of at least 400 to 500 mm can be used, so that structural bottlenecks or small space in the area between the boiler cover of the boiler 2 and platform 16, in which the hose guides run, no problems.

Zum Herausziehen des Schlauches 4 wird die erste Kupplung geöffnet, sodass sich die Vorschubrolle 20 frei drehen kann. Die Schlauchtrommel 37 ist dabei über die zweite Kupplung mit der Antriebswelle verbunden. Wenn der Schlauch 4 vollständig aus dem Spülrohr der Schlauchführung 5 herausgezogen ist, wird die Bremse 38 geschlossen, sodass ein Absacken der Düse 27 ausgeschlossen ist. Die zweite Kupplung wird dann wieder geöffnet.To pull out the hose 4, the first clutch is opened, so that the feed roller 20 can rotate freely. The hose reel 37 is connected via the second clutch to the drive shaft. When the tube 4 is completely pulled out of the flushing tube of the tube guide 5, the brake 38 is closed, so that a sagging of the nozzle 27 is excluded. The second clutch is then reopened.

Abschließend wird die Schlauchreinigungseinrichtung 26 aus dem Stutzen 17 herausgezogen. Nun kann die Reinigungsschlauchpositioniereinrichtung 3 entweder an dieser Stelle verharren oder zum nächsten Stutzen 17 einer anderen Schlauchführung 6 verfahren werden. Vorteilhaft ist es, wenn die Reinigungsschlauchpositioniereinrichtung 3 nach Abschluss der Reinigung auf eine definierte Parkposition gefahren wird, welche an einem in der Regel außen liegenden bestimmten Stutzen oder in einem Bereich außerhalb der Stutzen liegt.Finally, the hose cleaning device 26 is pulled out of the pipe 17. Now, the cleaning hose positioning device 3 can either stay in this position or be moved to the next pipe 17 of another hose guide 6. It is advantageous if the Reinigungsschlauchpositioniereinrichtung 3 is driven after completion of the cleaning to a defined parking position, which is located on a rule lying outside certain nozzle or in an area outside the nozzle.
