Definitions

  • 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.
  • radioactive water 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.
  • the tube bundle for example a condenser
  • 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.
  • 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.
  • 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.
  • 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.
  • the cleaning carriage can be moved in a guide carriage whose directions of movement cross one another at right angles.
  • 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.
  • 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.
  • 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.
  • the high-pressure hose can be moved by two friction rollers, which are driven by a hydraulic motor arranged on the cleaning trolley.
  • 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.
  • the carriages can be movable relative to one another and to the frame by means of pressure medium-xolben-cylinder units.
  • a pressure hose 21 is moved in a direction parallel to the condenser tubes 24 by two rollers 22, 23, one roller 23 of which is driven by a hydraulic motor 13.
  • the pressure hose 21 is guided by means of a hose guide tube nozzle 12.
  • a video camera 4 and two lights 5 are attached to the underside of the carriage 25.
  • the carriage slides on rollers 26 along the guides 27 of the intermediate frame 28. It is driven by a piston-cylinder unit 29.
  • the intermediate frame in turn slides on guides 30 of the frame 8 by means of rollers 9.
  • the intermediate frame 28 is driven by a piston-cylinder unit 31.
  • rollers 32 are attached, which allow a rotational movement of the frame 8 along the centering tube ring 11.
  • the frame 8 is driven by a hydraulic motor 10.
  • the device can be locked by four telescopic arms 3 on the flange 33 of the tube bundle to be cleaned.
  • clamping claws 35 are articulated on the flange 33 of the tube bundle.
  • the cleaning device is adjusted and locked via the spindle handwheels 34.
  • a slewing ring 6 which is freely rotatable relative to the carriage 25 is provided for this purpose.
  • the entire device is controlled by a manipulator.
  • This manipulator is located in a room that is not exposed to environmental pollution. It contains control elements for all movement possibilities of the cleaning device, namely the back and forth movement of the pressure hose 21 into and out of the condenser tubes 24, the movement of the carriage 25, the movement of the intermediate frame 28 and the rotary movement of the frame 8. It also contains switches for switching the high-pressure pump for the cleaning liquid on and off and a monitor for the video camera 4.
  • safety devices are provided, such as. B. limit switches that prevent a stop in the different directions of movement.
  • a limit switch can also be used to control the switching on and off of the high pressure pump for the cleaning liquid.
  • the guides are each encompassed by a plurality of rollers in order to enable safe sliding at different load directions.
