Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen radioaktiv kontaminierter Rohrbündel mit stirnseitig in einer Ebene liegenden offenen Enden, vorzugsweise von Rohrbündelkondensatoren, mit einem durch die Rohre schiebbaren Hochdruckschlauch, der an seinem vorderen Ende eine Spritzdüse für das Reinigungswasser trägt.The invention relates to a device for cleaning radioactive contaminated tube bundles with open ends lying on the end face in a plane, preferably tube bundle condensers, with a high-pressure hose that can be pushed through the tubes and carries a spray nozzle for the cleaning water at its front end.

Beispielsweise in Kernkraftwerken fällt eine große Menge radioaktiv verseuchten Wassers an, das durch Verdampfen dekontaminiert wird. Bei diesem Wasser handelt es sich zum großen Teil auch um Spülwasser, das zum Reinigen radioaktiv verseuchter Anlagenteile oder Kleidung benutzt worden ist und radioaktive Partikel enthält, die sich beim Verdampfen auf den Rohren des Verdampfers und Kondensators absetzen und dort den Wärmedurchgang behindernde Isolierschichten bilden. Um die Wirksamkeit von Wärmeaustauschern, Verdampfern, Kondensatoren und dergleichen, die der Leitung von radioaktiv verseuchtem Wasser dienen, aufrecht zu erhalten, müssen diese von Zeit zu zeit gereinigt werden. Dies geschieht gegenwärtig in der Weise, daß die Rohrbündel, beispielsweise eines Kondensators, geöffnet und von Hand durch die einzelnen Rohre ein an seinem vorderen Ende mit einer Spritzdüse versehener Hochdruckschlauch hindurchgeschoben wird, so daß das aus der Spritzdüse spritzende Wasser, das in dem Hochdruckschlauch einen Druck von 400 bis etwa 700 bar aufweisen kann, die Ablagerungen auf den Innenwandungen der Rohre entfernt. Als Spülwasser wird dabei vollentsalztes Wasser verwendet. Der Bedienungsmann ist dabei der starken radioaktiven Strahlung aus dem offenen Kondensatorkopf ausgesetzt, so daß er die Reinigungsarbeit nur für kurze Zeit ausführen kann und häufig abgelöst werden muß.In nuclear power plants, for example, a large amount of radioactive water is produced, which is decontaminated by evaporation. Most of this water is rinsing water, which is used to clean radioactive contaminants Parts of the system or clothing have been used and contain radioactive particles which, when evaporated, settle on the tubes of the evaporator and condenser and form insulating layers that prevent heat transfer there. In order to maintain the effectiveness of heat exchangers, evaporators, condensers and the like, which serve to conduct radioactive water, they have to be cleaned from time to time. This is currently done in such a way that the tube bundle, for example a condenser, is opened and pushed manually through the individual tubes through a high-pressure hose provided at its front end with a spray nozzle, so that the water spraying out of the spray nozzle is contained in the high-pressure hose Can have pressure of 400 to about 700 bar, the deposits on the inner walls of the tubes removed. Demineralized water is used as rinsing water. The operator is exposed to the strong radioactive radiation from the open condenser head, so that he can only carry out the cleaning work for a short time and often has to be replaced.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, mit der sich Rohrbündel im wesentlichen ohne manuelle Arbeit in deren unmittelbarer Nähe reinigen lassen.The object of the invention is therefore to provide a device of the type specified at the outset, with which tube bundles can be cleaned in the immediate vicinity thereof essentially without manual work.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der eingangs angegebenen Art dadurch gelöst, daß der Schlauch zwischen zwei mit einem Antrieb versehenen Vorschubrädern oder -rollen form- oder reibschlüssig mit zu den Rohren paralleler Vorschubrichtung gehalten ist, die in einem Reinigungswagen gelagert sind, der durch Antriebsmittel über die Ebene eines Rahmens verfahrbar und in seinen Reinigungspositionen feststell. bar ist, und daß der Rahmen Mittel zum Befestigen an dem Rohrbündel aufweist. Der den Hochdruckschlauch mit der Spritzdüse tragende Wagen läßt sich durch die Steuerungseinrichtungen in seinen Reinigungspositionen vor den einzelnen Rohren verfahren, in denen sodann der Schlauch ein- oder mehrmals durch die zu reinigenden Rohre hindurchgeführt wird. Manuelle Arbeit ist lediglich noch zum öffnen der Rohre und zum Befestigen des den Reinigungswagen tragenden Rahmens erforderlich.According to the invention, this object is achieved in a device of the type specified at the outset in that the hose is held in a form-fitting or frictional manner with two feed wheels or rollers provided with a drive with a feed direction parallel to the pipes, which are stored in a cleaning trolley which is driven by drive means Can be moved over the level of a frame and locked in its cleaning positions. bar, and that the frame has means for fastening to the tube bundle. The the high pressure hose with the spray nozzle Carrying car can be moved by the control devices in its cleaning positions in front of the individual pipes, in which the hose is then passed one or more times through the pipes to be cleaned. Manual work is only required to open the pipes and to fix the frame carrying the cleaning trolley.

Der Wagen ist mit Vorschubrädern oder -rollen oder einer anderen _geeigneten Vorschubeinrichtung für den Druckschlauch versehen, der an seinem vorderen Ende eine Düse mit vorzugsweise mehreren Düsenöffnungen trägt, durch die die Reinigungsflüssigkeit mit hohem Druck auf die Innenwandung der Rohre gesprüht wird.The carriage is provided with feed wheels or rollers or another suitable feed device for the pressure hose, which carries at its front end a nozzle, preferably with a plurality of nozzle openings, through which the cleaning liquid is sprayed onto the inner wall of the pipes at high pressure.

Der Reinigungswagen kann in einem Führungswagen verfahrbar sein, deren Bewegungsrichtungen rechtwinkelig einander kreuzen.The cleaning carriage can be moved in a guide carriage whose directions of movement cross one another at right angles.

Die Führungen nur des Reinigungswagens oder aber auch des Führungswagens können auf Trägern befestigt sein, die auf dem mit einer kreisrunden Führungsbahn versehenen Rahmen drehbar gelagert sind. Ist der Reinigungswagen auf dem drehbaren Träger radial verfahrbar, kann er durch Drehen der Träger und radiales Verfahren die gesamte Ebene der Öffnungsquerschnitte der zu reinigenden Rohre überstreichen. Sind die Führungen des Führungswagens drehbar gelagert, kann der Reinigungswagen durch eine Vierteldrehung der Träger jeweils etwa einen Quadranten überstreichen.The guides of only the cleaning carriage or also the guide carriage can be fastened on supports which are rotatably mounted on the frame provided with a circular guideway. If the cleaning carriage can be moved radially on the rotatable carrier, it can sweep over the entire plane of the opening cross sections of the pipes to be cleaned by rotating the carriers and radial movement. If the guides of the guide carriage are rotatably mounted, the cleaning carriage can sweep approximately one quadrant each time by a quarter turn of the carrier.

Die einzelnen Führungen können aus Rohren bestehen, wobei die Reinigungs- und/oder Führungswagen und/oder der diese tragende Träger mit jeweils mindestens drei Rollenpaaren versehen sind, die an gegenüberliegenden Seiten der Führungsrohre angreifen.The individual guides can consist of tubes, wherein the cleaning and / or guide carriages and / or the carrier carrying them are each provided with at least three pairs of rollers which engage on opposite sides of the guide tubes.

Die Genauigkeit und Stabilität des Führungssystems kann noch dadurch gesteigert werden, daß neben den Rollenpaaren an einer dritten-Seite der Führung eine dritte Laufrolle angreift, die beispielsweise in Querrichtung wirkende Kräfte aufnimmt.The accuracy and stability of the guide system can be increased by the fact that in addition to the pairs of rollers on one third-side of the guide attacks a third roller, which absorbs forces acting in the transverse direction, for example.

Der Hochdruckschlauch kann von zwei Friktionsrollen bewegbar - sein, die von einem auf dem Reinigungswagen angeordneten Hydromotor angetrieben werden.The high-pressure hose can be moved by two friction rollers, which are driven by a hydraulic motor arranged on the cleaning trolley.

In weiterer Ausgestaltung der Erfindung sind an dem Reinigungswagen eine Videokamera und Lampen angeordnet, die es der Bedienungsperson von einem entfernten Bedienungsstand erlauben, die Bewegungen des Reinigungswagens genau zu steuern.In a further embodiment of the invention, a video camera and lamps are arranged on the cleaning trolley, which allow the operator to control the movements of the cleaning trolley from a remote operating station.

Die Wagen können relativ zueinander und zu dem Rahmen durch Druckmittel-Xolben-Iylinder-Einheiten verfahrbar sein.The carriages can be movable relative to one another and to the frame by means of pressure medium-xolben-cylinder units.
