Title (EN) WATER TREATMENT DEVICE AND WATER TREATMENT METHOD
(FR) DISPOSITIF DE TRAITEMENT D'EAU ET PROCÉDÉ DE TRAITEMENT D'EAU
(JA) 水処理装置および水処理方法
Abstract:
(EN) The purpose of the present invention is to stabilize energy balance by controlling energy consumption required for cooling and heating while simplifying pipe structure. A water treatment device is provided with: a forward osmosis means for forming a diluted draw solution by moving water through a semipermeable membrane from an aqueous solution that includes water as a solvent in a draw solution having a cloud point; a heating means for heating the diluted draw solution to a temperature at the cloud point or greater; a water separation means for separating the diluted draw solution heated by the heating means into a water-rich solution and a regenerated draw solution wherein the water content is lower than the water-rich solution; an inflow-side heat exchange means for carrying out heat exchange between the aqueous solution and the regenerated draw solution flowing out of the water separation means; and an outflow-side heat exchange means for carrying out heat exchange between the diluted draw solution flowing out of the forward osmosis means and the water-rich solution flowing out of the water separation means.
(FR) La présente invention vise à stabiliser l'équilibre énergétique par une régulation de la consommation d'énergie requise pour le refroidissement et le chauffage, tout en simplifiant une structure de tuyauterie. Le dispositif de traitement d'eau comprend : un moyen d'osmose directe, qui forme une solution d'extraction diluée en faisant passer de l'eau à travers une membrane semi-perméable, à partir d'une solution aqueuse qui comprend de l'eau en tant que solvant dans une solution d'extraction présentant un point de trouble ; un moyen de chauffage pour chauffer la solution d'extraction diluée à une température supérieure ou égale au point de trouble ; un moyen de séparation d'eau pour séparer la solution d'extraction diluée chauffée par le moyen de chauffage en une solution riche en eau, et une solution d'extraction régénérée dont la teneur en eau est inférieure à la solution riche en eau ; un moyen d'échange de chaleur côté entrée d'eau, pour réaliser un échange de chaleur entre la solution aqueuse et la solution d'extraction régénérée sortant du moyen de séparation d'eau ; et un moyen d'échange de chaleur côté sortie d'eau, pour réaliser un échange de chaleur entre la solution d'extraction diluée sortant du moyen d'osmose directe et la solution riche en eau sortant du moyen de séparation d'eau.
(JA) 配管構造を簡素にしつつ、冷却や加熱に要する消費エネルギーを抑制して、エネルギーの収支を安定化することを目的とする。曇点を有するドロー溶液に、溶媒として水を含む含水溶液から半透膜を介して水を移動させて希釈ドロー溶液とする正浸透手段と、希釈ドロー溶液を曇点以上の温度に加熱する加熱手段と、加熱手段によって加熱された希釈ドロー溶液を、水リッチ溶液と水リッチ溶液より含水率が低い再生ドロー溶液とに分離する水分離手段と、含水溶液と水分離手段から流出した再生ドロー溶液との間で熱交換を行う流入側熱交換手段と、正浸透手段から流出した希釈ドロー溶液と水分離手段から流出した水リッチ溶液との間で熱交換を行う流出側熱交換手段と、を備える。
