Abstract

A cleaning apparatus for cleaning a cooling tube array of a heat exchanger, including a triangular truss beam supported to be movable in a first direction, which direction is perpendicular to a longitudinal direction of the truss beam, a nozzle carriage movably held on the truss beam, the nozzle carriage being movable along the longitudinal direction of the truss beam, and a plurality of cleaning nozzles mounted to the nozzle carriage, the truss beam having two tubular top chords and one tubular bottom chord that is arranged centrally below the top chords, and bracings that connect the chords, and the nozzle carriage having at least one bottom chord roller that is arranged for traveling on the bottom side of the bottom chord; and a cleaning apparatus having a square truss beam.

Claims8

Dependent claims

A cleaning apparatus for cleaning a cooling tube array of a heat exchanger, comprising:

a transverse beam supported to be movable in a first direction, which direction is perpendicular to a longitudinal direction of the transverse beam,
a nozzle carriage movably held on the transverse beam, the nozzle carriage being movable along the longitudinal direction of the transverse beam,
a plurality of cleaning nozzles mounted to the nozzle carriage,
a carrier chain, and
a supply tube connected to the plurality of cleaning nozzles,
wherein the supply tube is installed along the carrier chain,
wherein, at one end of the carrier chain, the carrier chain is connected to the nozzle carriage, and
wherein, distant from said one end, a part of the carrier chain is supported outside of the transverse beam in a position such that the nozzle carriage is enabled to pass said part when moving in a first traveling direction along the transverse beam, by moving in which direction an increasing portion of the carrier chain is laid onto a chain support.
