Definitions

  • the invention relates to a cleaning device for the inner surfaces of a heat exchanger, in particular a boiler. Furthermore, the invention relates to a heat exchanger with such a cleaning device.
  • Heat exchangers are known, for example, from conventional power plants, waste incineration plants or plants operated with organic fuels. These heat exchangers serve to transmit the thermal energy of a first fluid, for example a flue gas, contactlessly to a second fluid.
  • the second fluid may, for example, be deionized water (eg in the case of the steam generator of a conventional power plant) or a non-boiling heat transfer fluid (for example thermal oil).
  • a device for cleaning a flue of a combustion plant is known.
  • a leading the cleaning medium hose is introduced into the flue gas to be cleaned.
  • the cleaning medium can then be conducted to the inner walls of the flue gas duct via an end nozzle head of the hose.
  • a hose leading the cleaning medium can be introduced into the interior of the trigger to be cleaned.
  • the hose has at its end a rotating nozzle head, which can be driven by the cleaning medium.
  • the nozzle head has a complicated mechanism, on the one hand requires high initial investment and on the other hand, due to the high operating temperature and the aggressive ambient media has an increased susceptibility together with a short life. Furthermore, due to the aforementioned mechanism, the nozzle head has too large external dimensions in order to be able to achieve narrowly subdivided or angled inner surfaces of the heat exchanger.
  • the present invention is therefore based on the object to provide a cleaning device for the inner surfaces of a heat exchanger, with a cost-effective, gentle, reliable and thorough cleaning of the inner surfaces is possible.
  • a further object of the present invention is to specify a heat exchanger which is cost-effective, gentle, reliable and thoroughly cleanable.

  • the cleaning agent it is possible for the cleaning agent to be brought directly to any part of the inner surface of the heat exchanger, after which the use of the cleaning medium (for example water or air) can be carried out in a particularly targeted manner. Therefore, the cleaning device can be operated with a reduced cleaning medium volume flow. As a result, excessive cooling of immediately adjacent heat transfer surfaces (so-called thermal shock) can be avoided. Furthermore, the amount of cleaning medium can be reduced overall since the cleaning medium can be used in a more metered manner.
  • the cleaning medium for example water or air
