FLUID TREATMENT SYSTEM

A boiler feed water treatment system (1, 100, 200) that includes two or more water softeners (20, 21), a totalizer (4) for measuring a quantity of water treated by each softener (20, 21) between regeneration cycles, a hardness analyzer (5) for measuring the hardness of water treated by the softeners...

Zusammenfassung:	A boiler feed water treatment system (1, 100, 200) that includes two or more water softeners (20, 21), a totalizer (4) for measuring a quantity of water treated by each softener (20, 21) between regeneration cycles, a hardness analyzer (5) for measuring the hardness of water treated by the softeners (20, 21), a chemical doser (7, 107) for introducing a scale inhibitor into the feed water and a controller (9, 209a, 209b) for controlling the operation of the system (1, 100, 200). The controller (9, 209a, 209b) controls the chemical doser (7, 107) to introduce into or increase the concentration of a scale inhibitor introduced into the feed water if a hardness measured by the hardness analyzer (5) exceeds a first threshold and a water quantity measured by the totalizer (4) is below a second threshold. The controller (9, 209a, 209b) also shifts between the softeners (20, 21) if the measured hardness exceeds the first threshold and the measured water quantity exceeds the second threshold or if the measured hardness is less than the first threshold and the measured water quantity exceeds a third threshold. The second and third thresholds correspond respectively to a fraction and a multiple of the estimated treatment capacity of each of the softeners (20, 21). L'invention concerne un système de traitement d'eau d'alimentation de chaudière (1, 100, 200) qui comprend deux adoucisseurs d'eau (20, 21) ou plus, un totalisateur (4) pour mesurer une quantité d'eau traitée par chaque adoucisseur (20, 21) entre les cycles de régénération, un analyseur de dureté (5) pour mesurer la dureté de l'eau traitée par les adoucisseurs (20, 21), un doseur de produit chimique (7, 107) pour l'introduction d'un inhibiteur de tartre dans l'eau d'alimentation et un dispositif de commande (9, 209a, 209b) pour commander le fonctionnement du système (1, 100, 200). Le dispositif de commande (9, 209a, 209b) commande le doseur de produit chimique (7, 107) pour introduire ou augmenter la concentration d'un inhibiteur de tartre introduit dans l'eau d'alimentation si une dureté mesurée par l'analyseur de dureté (5) dépasse un premier seuil et une quantité d'eau mesurée par le totalisateur (4) est inférieure à un deuxième seuil. Le dispositif de commande (9, 209a, 209b) permet également de basculer entre les agents adoucisseurs (20, 21) si la dureté mesurée dépasse le premier seuil et la quantité d'eau mesurée dépasse le deuxième seuil ou si la dureté mesurée est inférieure au premier seuil et la q
