Abstract

The device has a cleaning tube/hose (2) with a cleaning medium (3) flowing through it. The cleaning tube/hose has known cleaning nozzles (4) and rotation nozzles at its end, where the rotation nozzles lie opposite to each other. The known cleaning nozzles and rotation nozzles jet the cleaning medium on a heating surface (1) with approximately 2500 revolutions.

Description

Die Erfindung betrifft die Verbesserung einer Reinigungseinrichtung für Feuerungen mit verschmutzten Abgasen. Bei diesen Feuerungen werden die Heizflächen (1) durch Ablagerungen verschmutzt. Durch diese Verschmutzung verringert sich der Wärmetransport. Die Tauscherflächen müssen daher regelmäßig gereinigt werden. Als Nachfolger der händischen Reinigung sind heute Maschinen im Einsatz. Diese Maschinen reinigen mittels eines Reinigungsmediums die Heizflächen. Das Reinigungsmedium wird z.B. mittels eines sich drehenden Rohres, an dessen Ende sich zwei herkömmliche Düsen befinden, zu den Tauscherflächen gesprüht. Der Nachteil ist, dass es sich um eine normale Düse mit einem daraus normalen Abreinigungsbereich handelt. Für eine gezielte Abreinigung von Heizflächen benötigt man einen hohen Zeiteinsatz. Es können daher mit diesem bekannten System die Heizflächen nur mit enormen Aufwand gereinigt werden.The invention relates to the improvement of a cleaning device for furnaces with polluted exhaust gases. In these firings, the heating surfaces ( 1 ) contaminated by deposits. This contamination reduces the heat transfer. The exchanger surfaces must therefore be cleaned regularly. Today, machines are in use as the successor of manual cleaning. These machines clean the heating surfaces by means of a cleaning medium. The cleaning medium is sprayed, for example by means of a rotating tube, at the end of which are two conventional nozzles to the exchanger surfaces. The disadvantage is that it is a normal nozzle with a normal Abreinigungsbereich. For a targeted cleaning of heating surfaces, it takes a lot of time. It can therefore be cleaned only with enormous effort with this known system, the heating surfaces.

Diese Erfindung stellt jetzt eine Weiterentwicklung der bekannten Maschinen dar.These Invention now represents a further development of the known machines represents.

Das Blasrohr (2) besitzt an seinem Ende anstelle der bekannten zwei Düsen (4) jetzt zwei Rotationsdüsen (6). Bisher bekannt sind in der Kesselreinigung Düsen (4) mit einem normalen Strahl. Die Reinigungsleistung kann durch den Düsendurchmesser (5), den Wasserdruck und die Düsenform verändert werden. Mit dieser Erfindung ist eine deutlich höhere Reinigungsleistung durch die Verwendung einer Rotationsdüse zu erreichen. Dabei wird der Düsenstrahl (5) mit ca. 2.500 Umdrehungen in Trichterform (5) auf die Heizflächen gesprüht. Anstelle von z.B. einem 3 mm großen Auftreffstrahl ergibt sich bei einem Abstand der Rotationsdüse zur Heizfläche von 300 mm und einem Winkel von 30 ° eine ca. 63-fach vergrößerte Reinigungsfläche. Durch den Rotorstrahl wird dann z.B. eine bestimmte Stelle in dieser Reinigungsfläche mit einer Frequenz von 42 mal in der Sekunde mit dem Wasserstrahl beaufschlagt und wieder nicht. Durch diese bekannte Wechselwirkung aus dem Rotorstrahl ist es jetzt erstmalig möglich, diese verbesserte Reinigungswirkung für große Heizflächen (1) einzusetzen.The blowpipe ( 2 ) has at its end instead of the known two nozzles ( 4 ) now two rotary nozzles ( 6 ). So far in the boiler cleaning nozzles ( 4 ) with a normal beam. The cleaning performance can be determined by the nozzle diameter ( 5 ), the water pressure and the nozzle shape are changed. With this invention, a significantly higher cleaning performance can be achieved by using a rotary nozzle. The nozzle jet ( 5 ) with about 2,500 revolutions in funnel shape ( 5 ) sprayed on the heating surfaces. Instead of, for example, a 3 mm impinging jet results in a distance of the rotary nozzle to the heating surface of 300 mm and an angle of 30 °, an approximately 63-fold enlarged cleaning surface. By the rotor jet then, for example, a certain point in this cleaning surface at a frequency of 42 times a second with the water jet is applied and not again. Through this known interaction of the rotor jet, it is now possible for the first time, this improved cleaning effect for large heating surfaces ( 1 ).
