ABSTRACT:
A device for recovering cleaning elements, such as form-rubber balls or other particles, from a heat-exchanger stream traversing a tube-bundle heat exchanger comprises a vertically oriented cylindrical housing or duct traversed axially by the main stream of heat-exchanger fluid and at least one separating sieve built into the housing for intercepting particles entrained in the stream and recovering them therefrom. The separating sieve is inclined to the axis of the housing and has, at least partially, an ellipsoidal boundary where it meets the inner wall of the housing. At the lower part of the sieve a collecting tube is provided, along the ellipsoidal boundary, and is formed with a laterally open longitudinally extending slit constituted a mouth through which the particles pass into this tube. A fitting at the low point of the tube conducts the collected particles from the collecting tube. The heat exchange stream flows in part tangentially into the collecting tube through the slit to induce the particles to pass cleanly from the sieve into this mouth.
