A tube-type heat exchanger having inlet and output conduits and tubes connected therebetween, and a return conduit extending from the output to the inlet conduit is, as is known, traversed by a coolant liquid from the intake to the output conduit through the tubes. Balls are released into the intake conduit from the return conduit and pass with the coolant through the tubes to clean same. These balls are trapped in the output conduit and introduced back into the return conduit where each ball's momentum is measured and outputs corresponding thereto are generated. These outputs are compared with a set-point signal corresponding to minimum acceptable ball momentum and all of the balls from the conduits are withdrawn and replaced with fresh balls when in a predetermined period of time a predetermined number of the outputs fall below the set-point signal.

Batch-type scrubbing-ball replacement system for heat exchanger

A tube-type heat exchanger having inlet and output conduits and tubes connected therebetween, and a return conduit extending from the output to the inlet conduit is traversed by a coolant liquid from the intake to the output conduit through the tubes. Balls are released into the intake conduit from the return conduit and pass with the coolant through the tubes to clean same. These balls are trapped in the output conduit and introduced back into the return conduit where each ball's momentum is measured and an output corresponding thereto is generated. This output is compared with a set-point signal corresponding to minimum acceptable ball momentum, and any ball whose momentum is below the minimum momentum is withdrawn from the return conduit and replaced in the conduits with a fresh ball.

Ball-measuring system for self-cleaning heat exchanger

A sluice for collecting cleaning bodies in the form of sponge rubber balls which are guided in the circulation of cooling water through the pipes of a heat exchanger having inlet and outlet connections, in particular a generating plant condenser, includes a return line passing through the sluice, the return line including an inlet line having a pump and an outlet line having a shut-off valve, a cylindrical housing including a sieve body and a shutting flap connected downstream of the sieve body, the housing being connected to the outlet connection of the heat exchanger through the inlet line and being connected to the inlet connection of the heat exchanger through the outlet line, and a flap trap disposed in the return line for the cleaning bodies between the outlet connection and the inlet connection of the heat exchanger. In order to catch the sponge rubber balls in the sluice after switching off the pump, to prevent a backflow of cooling water and thus to prevent a discharge of the balls, a flap trap which is capable of shutting off the inlet line is positioned inside the sluice housing.
