Definitions

  • the invention relates to a method for the automated cleaning of lamellar heat exchangers.
  • the invention also relates to an installation arrangement with a lamellar heat exchanger and a cleaning device for the lamellar heat exchanger.
  • the cleaning effect decreases with increasing Entry into the heat exchanger, that means more and more with greater depth. As a result, the front is clean.
  • the cleaned lamellar heat exchanger however, has poor passage values. This leads to greatly increased cleaning costs or to the fact that, because of the lack of heat dissipation through the lamellar heat exchanger, the output of a unit that interacts with the lamellar heat exchanger, for example a turbine output, has to be throttled. In addition, if the water jet hits the finned heat exchangers, the sensitive fins can be damaged.
  • a cleaning device for a heat exchanger which provides a longitudinally displaceable conductor and a nozzle assembly with a plurality of nozzles provided between the conductor and an upper side of the heat exchanger to be cleaned.
  • the nozzle assembly with the nozzles is held displaceably along the ladder.
  • a cleaning device for a condenser of a heat exchanger is known.
  • the cleaning device itself provides a receptacle for a cleaning tool, which is held displaceably along a traverse of the cleaning device.
  • the traverse is also held displaceably on two longitudinal bars of the cleaning device.
  • the object of the present invention is to provide an improved method for the automated cleaning of lamellar heat exchangers as well as a Specify installation arrangement with a lamellar heat exchanger and a cleaning device.

  • a roller attached to another end or a toothed wheel next to the guide unit are moved, whereby a carrier gas, preferably compressed air, and a liquid, preferably water, as a blasting agent, are supplied through supply hoses at a pressure of at least 2 bar, whereby the amount of water supplied is less than 1% , is preferably less than 0.30% of the amount of air supplied
  • the particular advantage of the invention is that the automated cleaning of the lamellar heat exchangers or other sensitive surfaces can be carried out quickly, completely, inexpensively and with a high quality.
  • a blasting medium with the carrier gas and the blasting agent ensures a good cleaning effect.
  • cleaning is very resource-efficient due to the small amount of water.
  • the cleaning is preferably carried out with a maximum pressure for the carrier gas of 16 bar.
  • a volume flow essentially depends on the pressure and a smallest cross section of the jet nozzle. It is, for example, 6 m 3 / min at a pressure of 6 bar.
  • the travel speed is preferably in the range from 10 to 450 mm / sec.
  • the pressure of the liquid supplied as blasting agent is above the pressure of the carrier gas.
  • the jet nozzle is designed, for example, as a convergent-divergent jet nozzle and then preferably as a Laval nozzle.
  • the nozzle can provide an annular opening gap for the blasting medium as well as a mixing chamber for the carrier gas and the blasting medium and a blasting medium distribution space surrounding the mixing chamber in sections in an annular manner.
  • the provision of the mixing chamber and the blasting agent distribution space which in any case is in the form of a ring segment, promote thorough mixing of the carrier gas with the blasting agent.
  • the good mixing ensures an improved homogeneity of the blasting medium and improves the cleaning effect.
  • the guide unit with the guide rails is fixed to a stair or bridge unit that can be rolled or pushed over the length of the exchanger.
  • large lamellar heat exchangers that are inclined relative to the horizontal are advantageously often equipped with stair or bridge units, for example for inspecting the heat exchangers. These can be in a longitudinal direction of the The heat exchanger can be moved.
  • the method can be carried out very easily and inexpensively if the existing structural components are reused and the mobility or displaceability of the stair or bridge unit is used to move the movement device with the jet nozzles attached to it.
  • the jet nozzles are attached to a vertically and laterally adjustable holder on the support arm.
  • the cleaning method can advantageously be adapted to different local conditions through the height adjustment or the lateral adjustment. For example, it may be necessary to adapt a cleaning device only in the area of the holder.
  • a control for carrying out the method is operated in an automated manner in such a way that the guide unit moves together with the staircase or bridge unit and, for this purpose, coordinates the movement device via the drive unit in the guide rails of the guide unit so that the jet nozzles are moved up and down Thoroughly clean the entire surface of the finned heat exchanger.
  • a movement in particular of the movement device in the guide rails can preferably take place continuously at a constant or variable speed.

  • the lamellar heat exchanger is cleaned in two stages.
  • a first cleaning stage a first partial surface of the lamellar heat exchanger is cleaned at a first, low speed by two or more jet nozzles that are spaced apart from one another.
  • a second cleaning stage the speed is then increased and another, second partial area of the lamellar heat exchanger is cleaned.
  • individual cleaning nozzles can be switched off at least optionally.
  • Two-stage cleaning is preferred if, due to the length of the jet nozzles, they have to be installed on the side of the stair or bridge unit and, due to the limited mobility of the stair or bridge unit, full-surface cleaning of the lamellar heat exchanger is only possible if on both opposite long sides the stair or bridge unit has at least one jet nozzle installed.

  • the installation arrangement has a controller for controlling the movement of the movement device and / or a quantity throughput for the blasting medium.
  • the guide unit with the movement device fixed in the guide unit is provided movably in a longitudinal direction of the lamellar heat exchanger and the control of the movement of the movement device is operated in such a way that all passage channels of the lamellar heat exchanger are exposed to the blasting medium and cleaned.
