Abstract

L'invention concerne un dispositif permettant de préparer de l'eau de condensat pure et d'utiliser de manière exhaustive les ressources de traitement chimique d'eau dans une centrale thermique. Le dispositif comprend un dispositif de condenseur de turbine à vapeur, un dispositif de traitement d'épuration d'eau de condensat, un dispositif de stockage d'eau de condensat pure et un dispositif de traitement chimique d'eau. L'invention concerne un dispositif permettant de préparer de l'eau de condensat pure et d'utiliser de manière exhaustive les ressources de traitement chimique d'eau dans une centrale thermique. Le dispositif comprend un dispositif de condenseur de turbine, un dispositif de traitement d'épuration d'eau de condensat, un dispositif de stockage d'eau de condensat pure et un dispositif de traitement chimique d'eau. L'eau de condensat concentrée contenant des ions ammonium est évacuée au moyen d'un dispositif de traitement par osmose inverse d'eau de condensat pure et est ajoutée à un dispositif d'ajout d'eau de chaudière au moyen d'une canalisation. L'eau adoucie générée par un dispositif de traitement chimique d'eau est recyclée, et les eaux usées acides et basiques générées par le dispositif de traitement chimique d'eau réagissent avec l'eau brute et sont recyclées. L'eau de condensat pure traitée par le dispositif de traitement par osmose inverse d'eau de condensat pure est divisée en plusieurs courants pour l'alimentation en eau. L'eau de condensat d'une centrale électrique est entièrement utilisée sans qu'aucun produit chimique ne soit nécessaire, de sorte que les exigences de la population quant à l'eau potable pure sont satisfaites, que les matières premières à proximité peuvent être utilisées et que le problème de la pollution de l'environnement par l'eau rejetée lors de la production d'eau potable est résolu.
