Title
(EN) DEVICE FOR SELECTIVE INSERTION OF CLEANING ELEMENTS INTO HEAT EXCHANGER TUBES
(FR) DISPOSITIF POUR INTRODUIRE SELECTIVEMENT DES ELEMENTS NETTOYANTS DANS DES TUBES D'ECHANGEURS DE CHALEUR
Abstract
(EN) 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.
(FR) Dispositif pour introduire sélectivement des éléments nettoyants (6) dans les tubes (5) d'échangeurs de chaleur (1). Les régions partielles de la plaque tubulaire (4), dans laquelle les éléments sont introduits, sont sélectionnées de manière à être si petits qu'un seul tube (5) à la fois peut être traité par les éléments nettoyants (6). On exclut ainsi les accidents statistiques, de sorte que les tubes (5) fragiles, par exemple ceux réalisés en alliage de cuivre, sont nettoyés ni trop souvent ni trop rarement, et qu'en conséquence on obtient un bon rendement pour une faible corrosion.
