Definitions

  • the invention relates to a particularly portable cleaning device for heat exchangers, in particular for air conditioning systems.
  • Air condensation plants are used as a closed system for condensing the exhaust steam or the excess steam of turbine plants.
  • the total cooling surface is designed for the amount of steam produced. It is assumed that a certain heat transfer from the cooling surface into the ambient air. The heat transfer, however, does not remain constant. On the cooling surfaces it comes to the outside for pollution. Pollution is caused, inter alia, by pollen, leaves, industrial emissions, flue dust and leads to deposits on the cooling surfaces. As a result, the heat transfer deteriorates.
  • Turbines are designed for an exhaust steam pressure of O, 2bar absolute, they are switched off with an increase in the vapor pressure to 0.8 bar by monitoring devices.
  • the cleaning is carried out manually.
  • the cleaning work is usually transferred to the cleaning crews, which are also subject to other cleaning work. There is a tendency to award this work as a complete package.
  • the cooling surfaces are arranged in multiple layers or consist of fin coolers with very high ribs. In the case of multi-layer cooling tubes, an improper procedure or the use of unsuitable equipment only causes a loosening of dirt on the upper layer and an attachment to lower rows / layers. Cooling surfaces with high ribs are at the same risk. On the way, the cooling air can even be blocked from passing through the radiator.
  • An older proposal provides stationary cleaning facilities, with which a reliable cleaning of the cooling surfaces is achieved.
  • the cleaning nozzles, their position and the cleaning pressure can be adapted to the cooling surfaces. This will allow actual cleaning without the risk of damage.
  • Another prior proposal provides that a cleaning device for multiple cooling surfaces (cooling registers) of a system is used. This is achieved by means of a driving system.
  • the driving system resembles a crane track, with which the device is converted from one cooling surface to the other.
  • a portable cleaning device is provided with a vertically over the height of the cooling register extending carriage, which is horizontally movable and carries a vertically movable thereon nozzle.

  • the cleaning device has a support structure with a running in the direction of the trolley edge profile and the carriage is arranged movable on the edge profile and / or the support structure is length-adjustable by connectors
  • two or more Kantproflle can be arranged side by side.
  • the use of a single edge profile involves a special step towards an optimally lightweight and functionally reliable device.
  • the weight advantage of a single edge profile is not readily apparent, because several side by side arranged edge profiles with the same cost of material computationally have a greater bending resistance than a single edge profile. Nevertheless, it is not just about the larger moment of resistance. It is also important that the guide rollers do not cause deformation of the rolling surfaces. This leads to a minimum thickness of the rolling surfaces and edge profiles. Two minimum-thickness edge profiles can result in a greater cost of materials than a single, stable edge profile.
  • the edge profile is formed as a hollow profile and length-adjustable by connectors.
  • the extensibility facilitates work with a single device at different Lukos or the like. Regardless of the edge profile of the extensibility and the connector are therefore also of particular importance.
  • the edge profile and the plug connection are favorable for a change in length.
  • the edge profile can be composed of several parts.
  • the device may also have a head and a foot and between the head and foot a changeable for length change edge profile.
  • the plug-in connection is brought about by means of separate spikes / pins, which engage in two pipe ends to be connected to each other. But it can also mandrels / cones on the

  • the arms and / or head and / or foot may be releasably assembled from parts so that replacement in adaptation to particular needs is possible.
  • the drive includes a power transmission means such as a belt, chain, rope or belt, in particular a toothed belt, and a geared motor with a drive pinion.
  • a power transmission means such as a belt, chain, rope or belt, in particular a toothed belt
  • the power transmission means is preferably passed over the head and foot and generates the necessary tension.
  • the associated roller / wheel / disc is adjustable transversely to the longitudinal direction of the power transmission means.
  • the power transmission means engages the carriage and is moved by means of the geared motor. In this case, the power transmission means can be guided around the drive pinion or pressed by means of another roller / wheel / disc against the drive pinion.
  • the use of aluminum for the profiles and a limited width of the nozzles or the nozzle assembly in the carriage contribute.
  • the restriction is given with the number of nozzles arranged on a pipe in the nozzle.
  • the nozzles or the nozzle block can clean all the cooling tubes below by processes along the entire width / length of the trolley.
  • the heavy weight reduction also protects the cooling coils. This is especially important for cooling coils with sensitive cooling fins.
  • the sensitive cooling tubes / ribs include e.g. those with rectangular cross-section, between which the cooling fins are guided back and forth as a meandering metal band.
  • the low weight brings no risk of excessive load on the cooling coil with it.
