Definitions

  • the invention relates to a method for removing deposits located on or in contact areas or parts of installations of plants through which gases or liquids flow, in particular to the continuous operation of the installations and devices for carrying out the method
  • the object of the invention was to design a cleaning method which solves the problem of thorough cleaning of the plant areas or system parts to be cleaned while avoiding the disadvantages occurring according to the prior art.
  • This object is achieved in accordance with the invention with a method for removing deposits located on or in contact areas or parts of installations of installations through which gases or liquids flow, in particular during operation of the installations by cooling the transferred into the system to be cleaned components of the used cleaning device, with which the system areas to be cleaned or system parts of the system are cleaned by targeted Laserbeaufschlagung the system areas or system components is marked.
  • the inventive method can during operation of the system areas to be cleaned or the system parts to be cleaned, ie at prevailing in the system to be cleaned high temperatures.
  • downtimes of the plant are avoided. This does not exclude the cleaning of the system when the system is at a standstill. Waiting times are also avoided before known cleaning devices can be used. Further disadvantages, which are mentioned in the introduction and associated with known purification processes, are avoided.
  • the laser impinging on the deposits to be removed dissolves the deposits from the plant areas or plant parts from which the deposits are to be removed, are thinner deposits by melting or evaporation, with thicker layers offers the removal of these deposits targeted laying of cuts in the coverings resulting from thermal shock or predetermined breaking points, optionally then also the cutting off of the coverings from the system areas or system parts to be cleaned.
  • the method also lends itself to the removal of scale on the walls of liquids containing or flowed through by plants or plant parts, in particular of turbine parts, without these parts must be dismantled, then for the decontamination of contaminated plant parts, such as in nuclear power plants .
  • Another application is the removal of worn on plant parts worn coverings, such as on the plant areas or system parts located, the system parts or plant areas against them by flowing aggressive media protective, worn rubber flooring.
  • the cleaning process is carried out with a through an access opening to be cleaned system area into the area to be cleaned, from the switchable, focused on the lance tip laser lance of heat resistant material, the lance weight reducing, expediently a lance penetrating, the laser transporting fiber optic cable is provided.
  • Lower lance weight opens up the possibility of using longer lances with which deposits of areas remote from the access opening to the system area to be cleaned can also be removed.
  • an optical system assigned to the lance it is possible to monitor the cleaning of the area of the system to be cleaned or of the system parts to be cleaned.
  • outside air can be fed through the lance of the lance tip.
  • the lance is expediently coated with the infrared radiation which occurs during the cleaning of the plant areas or plant parts, resulting in a reduction in the heating of the lance.
