The invention concerns an apparatus for cleaning liquid fluids, in particular for the cooling water running to a heat exchanger, having a portion of pipe of circular cross section as a housing, a screening body and a suction device, which can be moved about an axis, on the inflow side for regional suction removal and consequently for cleaning the screening body. To provide broad freedom of design for shaping the apparatus in a simple way, while the advantages of the known apparatuses are to be essentially retained, it is provided according to the invention that the apparatus is provided with a portion of pipe of circular cross section as a housing and with a screening body which extends transversely in the portion of pipe and the cross section of which is designed as a U shape which is open toward the inflow side and has a bending radius that is constant in the bent region, or as part of this U shape, as well as with a suction device, which is arranged on the inflow side of the screening body and is arranged such that it can be moved about an axis lying transversely in the portion of pipe and serves for regional suction removal and cleaning of the screening body.

A process of cost-optimized control of a mechanical filter that is situated in a flow of cooling water driven by a cooling water pump in a heat exchanger and that can be regenerated by means of a flushing system involves the following steps: at least one measurement value is determined from which the filter's current degree of soiling is derived and this value is fed to a flush command generator; by means of the functional dependencies and/or data stored in the flush command generator a first and a second performance loss are calculated at predeterminable intervals, the first performance loss comprising the performance loss due to the filter's degree of soiling and the second performance loss comprising the performance loss due to a flushing operation at the current degree of soiling; from the progression over time of the first computed performance loss are determined the total performance losses since the last regeneration as a result of the soiling of the filter; a current second energy loss is calculated for each regenerating operation, containing the second performance loss multiplied by the duration of the regenerating operation; each current second energy loss is added in to the currently accumulated total energy loss and the sum is divided by the time expired since the last regeneration, including the time required for a regenerating operation; the progression over time of this quotient is monitored and a regenerating operation is triggered when this quotient has gone through a minimum and is rising again.

Cleaning member for cleaning the interior of heat exchanger tubes by rotating, including a sponge rubber element being adapted to suit the diameter of the heat exchanger tube, and abrasive elements connected to the sponge rubber body, the abrasive elements being in the form of bristles each having a bristle shaft, and a bristle base molded into the sponge rubber ball anchoring the bristles.

Cleaning member for cleaning the interior of heat exchanger tubes

Cleaning member for cleaning the interior of heat exchanger tubes by rotating, including a sponge rubber body having a given diameter, an adhesive film disposed on the sponge rubber body, and an abrasive layer formed of granular abrasive elements being fastened on the sponge rubber body by the adhesive film, the granular abrasive elements having an average linear dimension being smaller than the given diameter of the sponge rubber body, and the granular abrasive elements being disposed in a loose packing causing the abrasive layer to be deformable together with the sponge rubber body.
