Abstract
Verfahren zur Reinigung der Heizflächen in Dampferzeugern von Kraftwerken und Heizwerken, wobei in eine Rohrgasse der zu reinigenden Heizflächen ein Druckmittelschlauch eingeführt und mittels Spritzdüse Hochdruckwasser auf die Heizflächen aufgespritzt und die Spritzdüsenbohrungen gegenüber den Heizflächen verändert wird. Der Druckmittelschlauch wird als U-förmige Schlauchschlaufe in die Rohrgasse eingeführt. Das Hochdruckwasser wird impulsausgeglichen aus zumindest zwei gegenüberliegenden Spritzdüsenbohrungen ausgespritzt. Die Spritzdüsenposition kann von oberhalb der Rohrgassen aus durch Veränderung der Länge und/oder Position der Schenkel der U-förmigen Schlauchschlaufe verändert werden.Process for cleaning the heating surfaces in steam generators of power plants and heating plants, whereby a pressure medium hose is inserted into a pipe lane of the heating surfaces to be cleaned and high pressure water is sprayed onto the heating surfaces by means of a spray nozzle and the spray nozzle bores are changed in relation to the heating surfaces. The pressure medium hose is inserted into the pipe lane as a U-shaped hose loop. The high pressure water is sprayed with equal pulses from at least two opposite spray nozzle bores. The spray nozzle position can be changed from above the pipe lanes by changing the length and / or position of the legs of the U-shaped hose loop.
Description
f tiefsten Punkt des U-Bogens 3 die Spritzdüse 2 aufweist c Diese Spritzdüse 2 ist eine im Sinne der obigen Ausführungen impulsausgeglichene Spritzdüse. Sie besitzt zumindest zwei ausreichend genau gegenüberliegende • Spritzdüsenbohrungen 4. Wie die Spritzdüse 2 im ein-■i zelnen aufgebaut ist entnimmt man aus einer vergleif chenden Betrachtung der F i g. 3 und 4. Man erkennt \ daß die Spritzdüse 2 zwei, vier oder sechs equidistant \ und paarweise diametral einander gegenüberliegende, - impulsausgeglichene Spritzdüsenbohrungen 4 aufweist ■ Das Hochdruckwasser tritt impulsausgeglichen ausf the lowest point of the U-bend 3 has the spray nozzle 2 c this spray nozzle 2 is a pulse-balanced spray nozzle in the sense of the above explanations. It has at least two spray nozzle bores 4 that are sufficiently exactly opposite one another. How the spray nozzle 2 is constructed in detail can be seen from a comparative consideration of FIG. 3 and 4. It can be seen \ that the spray nozzle 2, two, four or six equidistant \ and in pairs diametrically opposite, - pulse-balanced spray nozzle bores 4 has ■ The high pressure water enters pulse offset from
den zumindest zwei gegenüberliegenden Spritzdüsenbohrungen 4 und wird auf die zu reinigenden Rohre R aufgespritzt Die Spritzdüsenposition ist von oberhalb der Rohrgasse aus durch Veränderung der Länge und/ oder der Position der Schenkel 5 der U-förmigen Schlauchschlaufe veränderbar. In den F i g. 1 und 2 erkennt man Pfeile, die diese Positionsveränderung verdeutlichen. Der Pfeil /in Fig. 1 deutet an, daß eine horizontale Bewegung möglich ist Der Pftil Il verdeutlicht die Aufwärtsbewegung, der Pfeil III die Abwärtsbewegung. Mit der Pfeilkombination IV ist die wechselnde Bewegung angedeutet die durch eine entsprechende gleichsam gegenläufige Veränderung der wirksamen Länge der U-Schenkel 5 erreicht wird. Je nach den betrieblichen Verhältnissen lassen sich auch andere Bewegungen einrichten. Jedenfalls erreicht man eine stetige Veränderung der Düsenlage, wie es z. B. in F i g. 2 angedeutet ist Gleichzeitig deutet F i g. 2 an, daß man in dem Schlauch mit Abstand voneinander, auch mehrere Spritzdüsen 2 anordnen könnte. Im allgemeinen wird man den Druckmittelschlauch 1 an einer entsprechend verfahrbaren Vorrichtung befestigen, die außerdem Trommeln zum Auf- und Abspulen der Schenkel aufweisen kann.the at least two opposite spray nozzle bores 4 and is sprayed onto the pipes R to be cleaned. The spray nozzle position can be changed from above the pipe lane by changing the length and / or the position of the legs 5 of the U-shaped hose loop. In the F i g. 1 and 2 can be seen arrows that illustrate this change in position. The arrow / in Fig. 1 indicates that a horizontal movement is possible. The Pftil II illustrates the upward movement, the arrow III the downward movement. The alternating movement is indicated by the arrow combination IV, which is achieved by a corresponding, as it were counter-rotating change in the effective length of the U-legs 5. Depending on the operational conditions, other movements can also be set up. In any case, a constant change in the nozzle position is achieved, as is the case, for. B. in Fig. 2 is indicated At the same time, F i g. 2 indicates that several spray nozzles 2 could also be arranged in the hose at a distance from one another. In general, the pressure medium hose 1 will be attached to a correspondingly movable device which can also have drums for winding and unwinding the legs.
Es versteht sich, daß im Rahmen der Erfindung durch Einsatz einer entsprechenden Vielzahl der beschriebenen Vorrichtungen auch mehrere Rohrgassen gleichzeitig gereinigt werden können. Die mehreren Vorrichtungen sind dann zweckmäßig parallel zueinander angeordnet und geschaltet.It is understood that within the scope of the invention by using a corresponding plurality of the described Devices can also be cleaned several pipe lanes at the same time. The multiple devices are then appropriately arranged and connected parallel to one another.
