Abstract (en)

The installation for the control of cleaning solids circulating in a heat exchanger (10) comprises a solid interception means (17) interposed in the exchanger outlet pipe (12). A pump (24) produces a counter flow through the interception means and its suction recovers the cleaning solids held by it. Return piping (28) recycles a return flow containing solid cleaning elements to the exchanger inlet pipe (11). A concentration device, comprising a pivoting grille (35), divides the return flow into two parts (P1,P2). The first part contains all the solid cleaning elements and the second part contains no cleaning solids.

Abstract (fr)

Installation de gestion pour éléments solides de nettoyage circulant dans un échangeur de chaleur (10), du genre comportant des moyens d'interception (17) qui sont interposés sur la canalisation de sortie (12) de l'échangeur de chaleur (10), une conduite de retour (28), qui recycle vers la canalisation d'entrée (11) de l'échangeur de chaleur (10) un flux de retour contenant les éléments solides de nettoyage, et un dispositif de gestion (26) de ces éléments solides de nettoyage : entre les moyens d'interception (17) et le dispositif de gestion (26), se trouve interposé un dispositif de concentration (27) divisant le flux de retour en deux parties (P1, P2), à savoir, une première partie (P1) qui contient normalement tous les éléments solides de nettoyage, et qui est dirigée vers le dispositif de gestion (26), et une deuxième partie (P2) qui est normalement dépourvue de tout élément solide de nettoyage, et qui est écartée du dispositif de gestion (26) ; la conduite de retour (28) appartient à des moyens de circulation qui sont propres à engendrer à travers les moyens d'interception (17) une circulation à contre-courant et qui comprennent des moyens d'aspiration adaptés à reprendre, au droit des moyens d'interception, les éléments solides de nettoyage retenus par ceux-ci ; le dispositif de concentration (27) comporte une grille (35) montée pivotante en sorte qu'elle peut occuper deux positions, une "de nettoyage" et une "hors nettoyage". <IMAGE>
