VORRICHTUNG ZUR SELEKTIERTEN ZUFUEHRUNG VON REINIGUNGSKOERPERN IN DIE ROHRE VON WAERMETAUSCHERN

摘要

Device for selective insertion of cleaning elements (6) into the tubes (5) of heat exchangers (1). The partial regions of the tube sheet (4) into which the elements are inserted are designed to be so small that only one tube (5) at a time can be processed by cleaning elements (6). In this way, statistical accidents are excluded, so that sensitive tubes (5), for example those made of a copper alloy, are cleaned neither too often nor too infrequently, and consequently a high efficiency is achieved with a low degree of corrosion.
