Abstract
Description
Es ist allgemein bekannt, dass Wärmetauscher, Abhitzekessel oder Brennkammern, also Räume, in denen eine Verbrennung stattfindet und die mit entsprechenden Leitungen versehen sind, durch die ein zu erwärmendes Medium strömt, in gewissen Zeitabständen gereinigt werden müssen. Der Grund für diese Reinigung besteht darin, dass die Leitungen, die von dem zu erwärmenden Medium durchströmt werden, an ihrer Aussenseite durch den Brennvorgang innerhalb des Brennraumes versotten bzw. von einer Schicht von Brennrückständen bedeckt sind, die den Wärmeübergang erschweren bzw. verhindern, was letztlich den Wirkungsgrad der Anlage vermindert.It is generally known that heat exchangers, waste heat boilers or combustion chambers, ie spaces in which combustion takes place and which are provided with corresponding lines through which a medium to be heated flows, have to be cleaned at certain intervals. The reason for this cleaning is that the lines through which the medium to be heated flows, are sputtered on the outside by the firing process within the combustion chamber or are covered by a layer of firing residues, which hinder the heat transfer or prevent what ultimately reduces the efficiency of the system.
Es ist bereits auch bekannt, dass zur Reinigung solcher Räume und Leitungen sog. Explosionsreinigungen durchgeführt werden. Hierzu wird beispielsweise ein Textilsack ausserhalb des zu reinigenden Raums mit einem Gasgemisch gefüllt und in den Raum, der gereinigt werden soll, eingebracht und dort zur Explosion gebracht. Bei einem solchen Verfahren entsteht eine kugelförmige Abreinigung, da die gesamte Sprengwirkung vom Textilsack, der idealerweise als Kugel angenommen werden kann, ausgeht. Das Problem hierbei ist, dass zwar Verschmutzungen, die aussenseitig auf den Leitungen bzw. Rauminnenwänden aufgebracht sind und die direkt von der Sprengwirkung erreicht werden können, möglicherweise beseitigt werden können. Da jedoch die Leitungen, die das zu erwärmende Medium aufnehmen, oftmals sehr eng zueinander liegen, kann die Sprengwirkung nur einen kleinen Teil der Verunreinigungen ablösen, häufig jedoch nicht Verunreinigungen, die zwischen den Rohren oder von der Sprengung aus gesehen hinter den Rohren liegen.It is also known that so-called. Explosionsreinigungen be performed to clean such spaces and lines. For this purpose, for example, a textile bag is outside the space to be cleaned filled with a gas mixture and introduced into the room to be cleaned, and there brought to the explosion. In such a process results in a spherical cleaning, since the entire explosive effect from the textile bag, which can be ideally assumed as a ball emanates. The problem here is that, although contaminants that are applied to the outside of the pipes or room interior walls and that can be achieved directly from the blasting effect, may possibly be eliminated. However, since the lines that receive the medium to be heated are often very close to each other, the blasting action can only remove a small portion of the contaminants, but often impurities that are behind the tubes between the tubes or from the blast.
Hier setzt die Erfindung an, die sich die Aufgabe gestellt hat, die bisherigen Nachteile zu vermeiden und darüber hinaus auch eine Reinigung zu erlauben, wenn die Temperatur innerhalb des zu reinigenden Raumes noch nicht auf Raumtemperatur oder eine Temperatur unterhalb 100 °C abgesunken ist.This is where the invention, which has set itself the task of avoiding the previous disadvantages and also to allow a cleaning when the temperature within the room to be cleaned has not yet dropped to room temperature or a temperature below 100 ° C.
Die Aufgabe wird durch ein Verfahren mit den Merkmalen nach Anspruch 1 und eine Vorrichtung mit den Merkmalen nach Anspruch 4 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen beschrieben.The object is achieved by a method having the features of
Gemäss der Erfindung wird nicht eine kugelförmige Sprengung innerhalb des Brennraums durchgeführt, sondern eine lineare Sprengung, d. h. also eine Sprengung, bei welcher die Sprengwirkung auf eine grosse Länge verteilt ist. Hierzu wird ein Rohr, z. B. ein Rohr aus Pappe und/oder Kupfer, mit einem Gasgemisch gefüllt und/oder innenseitig mit einer Sprengschnur versehen, so dass durch die Sprengung die gewünschte Sprengwirkung erzielt werden kann. Durch die Explosion gemäss der Erfindung wird eine Schockwelle erzeugt, die bei Auftreffen auf abzureinigende Verschmutzungen diese absprengt. Durch den geringen Rohrdurchmesser ist auch eine Reinigung zwischen den verunreinigten Leitungen bzw. Leitungsbündeln möglich und wenn das Sprengrohr von einem Kühlmedium durchströmt wird, kann auch die Reinigung während des Betriebs oder nach einer kurzfristigen Abschaltung des Betriebs erfolgen, wenn die Temperatur innerhalb des Brennraums (des Wärmetauschers) noch nicht sehr weit abgesunken ist. Dies erlaubt es, dass für die Reinigung selbst keine relevanten Ausfallzeiten, wie sie bislang von bis zu mehreren Tagen üblich sind, verursacht werden.According to the invention, a spherical detonation within the combustion chamber is not performed, but a linear detonation, i. H. So a blast, in which the explosive effect is distributed over a large length. For this purpose, a pipe, z. As a tube made of cardboard and / or copper, filled with a gas mixture and / or inside with a detonating cord, so that the desired explosive effect can be achieved by the blasting. Due to the explosion according to the invention, a shock wave is generated, which breaks off when it hits dirt to be cleaned off. Due to the small pipe diameter, a cleaning between the contaminated lines or trunk groups is possible and when the blast is traversed by a cooling medium, the cleaning during operation or after a short-term shutdown of the operation can take place when the temperature within the combustion chamber (the Heat exchanger) has not fallen very far. This makes it possible for the cleaning itself no relevant downtime, as they are customary for up to several days, caused.

Die Erfindung ist nachfolgend anhand von Beispielen erläutert:
-
zeigt einFigur 1Rohr 1, vorzugsweise Papprohr, welches eine Zündkerze (Zünder) 2 aufnimmt. Das Rohr ist einerseits mit einem Verschluss versehen und auf der anderen Seite ist ein Gaseinfüllstutzen ausgebildet. -
zeigt die gesamte Vorrichtung in zusammengesetzten Zustand.Figur 2
-
FIG. 1 shows atube 1, preferably paperboard, which receives a spark plug (igniter) 2. The tube is on the one hand provided with a closure and on the other side a gas filler neck is formed. -
FIG. 2 shows the entire device in assembled condition.
Das Rohr kann je nach Einsatz beliebig lang gemacht werden und, wie im dargestellten Beispiel zu sehen, weist das Rohr einen relativ kleinen Durchmesser von beispielsweise 3 cm bis 15 cm auf, so dass es auch in die Gassen der Wärmetauscherleitungen innerhalb der Brennkammer eingebracht werden kann.The tube can be made arbitrarily long depending on the application and, as seen in the example shown, the tube has a relatively small diameter of for example 3 cm to 15 cm, so that it can also be introduced into the lanes of the heat exchanger lines within the combustion chamber ,
Nach Auslösung der Sprengung, durch die das gesamte (Papp)rohr zerlegt wird, können die Teile wie Füllkopf-Löschzündkerze, Gewindestange, Verschluss usw. wieder weiter verwendet werden.After the detonation, which disassembles the entire (cardboard) pipe, the parts such as filling head extinguishing spark plug, threaded rod, shutter etc. can be reused.
Wird nunmehr zwischen die beschriebene Anordnung ein Brennraum eingebracht, und zwar dort zwischen Rohrbündel (-leitungen) 8 und 9, so kann mittels der Auslösung der Sprengung, also mittels der Explosion die Reinigung der Rohre vorgenommen werden, und damit die Sprengung nicht zu einem unerwünschten Zeitpunkt erfolgt, wird das Rohrinnere mittels zugeführten Wassers (bzw. zugeführter Luft), welches über das erste Rohr 1 einströmt entsprechend gekühlt, so dass eine unerwünschte Auslösung der Explosion sicher verhindert werden kann.Now, if a combustion chamber is introduced between the described arrangement, namely between tube bundle (lines) 8 and 9, so by means of the triggering of the blast, ie by means of the explosion, the cleaning of the tubes are made, and thus the blasting is not an undesirable Timing takes place, the tube interior by means of supplied water (or supplied air), which flows in via the
Innerhalb des zweiten Rohres 2 ist eine Sprengschnur (und ggf. ein explosives Gasgemisch) ausgebildet und die Sprengschnur ist mit dem Zünder verbunden. Wie in der
Wird die Sprengung ausgelöst, so wird das äussere Rohr 2, z. B. wenn dieses aus Pappe, Glas, Metall, Kupfer oder Kunststoff gefertigt ist, zersplittert (zerstört) (wie bei einer Handgranate) und die einzelnen abgesprengten Partikel treffen auf die Verunreinigung an den zu reinigenden Rohren innerhalb der Brennkammer. Die Verunreinigungen werden hierbei abgelöst.If the blast is triggered, the
Ist der Zünder mit einem Temperatursensor versehen, so kann die Kühlmenge so eingestellt werden, dass eine unvorhergesehene Sprengung nicht vorzeitig verursacht wird.If the igniter is equipped with a temperature sensor, the cooling amount can be adjusted so that an unforeseen detonation is not prematurely caused.
Wie in den dargestellten Beispielen auch zu sehen, sind die Sprengrohre so bemessen, dass sie auch zwischen die zu reinigenden Leitungen innerhalb des Brennraumes passen und somit auch Verunreinigungen von den Leitungen abgelöst werden können, die vom Brennraum aus gesehen zwischen den Leitungen oder hinter diesen liegen.As can also be seen in the illustrated examples, the blasting pipes are dimensioned so that they also fit between the lines to be cleaned within the combustion chamber and thus contaminants can be removed from the lines, which are seen from the combustion chamber between the lines or behind them ,
