Mobile cleaning device for cooling surfaces, comprises carriage with rotary nozzles mounted on rotary spray arms

摘要

The cleaning device has a carriage (25) which can be moved along the cooling pipes or tubes, especially in the length direction, and can extend over one or more of these pipes or tubes. The carriage has a rotary spray arm (29) extending in the pipe or tube length direction and this arm has at least one rotary flat nozzle (30) for spraying the cooling surface with a cleaning fluid, especially water. The arm and nozzle are connected together in such a way that the nozzle position remains essentially unchanged relative to the pipe or tube length direction during arm rotation.
