ABSTRACT:
A continuous condenser backflush system includes a hollow wand attached perpendicularly to a hollow shaft. The wand is moved in lateral increments across the condenser face. The wand is retracted from the condenser face for moving laterally to a new position before again being extended to the condenser face to collect and dispose of the trash caught under the wand. Trash caught on the condenser face is flushed by a stream of water back through the shaft to a mesh basket where it is separated from the water. A pump may be provided on the shaft for injecting and circulating cleaning fluids (such as chemical and/or abrasive fluids) through the condenser. A similar wand system may be provided on the remote face of the condenser to receive the fluids and return them to a recovery tank for recycling. The pump may also circulate dehumidified air through the system to keep the condenser dry when the cooling water circulating pump is shut down. A method of using the system is described.
