<p>PURPOSE:To provide a concentrator efficient in invested energy by providing a heat exchanger connected to the route of a dilute solution between the heat release route and the heat absorbing route of a heat pump, arranging the heat release route in a regenerator as the route of a heat transfer medium for heating and arranging the heat absorbing route in a condenser as the route of the heat transfer medium for cooling. CONSTITUTION:Heat exchangers 9, 10 connected to the route 11 of a dilute solution are provided between the heat release route 15 and the heat absorbing route 17 of a heat pump 8. The heat release route 15 is arranged in a regenerator 5 as the route of a heat transfer medium for heating. The heat absorbing route 17 is arranged in a condenser 7 as the route of the heat transfer medium for cooling. The route 11 of a dilute solution and the route 12 of a concentrated solution are provided in the regenerator 5. The outlet 13 of condensate is provided in the condenser 7. Thereby the dilute solution supplied from a heating tower 2 is branched from the heat collection route 3 of brine and heated by the heat exchangers 9, 10, heated and concentrated by the heat release route 15 of the heat pump 8 in the regenerator 5. Generated vapor is cooled through the heat absorbing route 17 in the condenser 7 and condensed and the condensate is discharged. Energy incorporated in the generated vapor is recovered by the heat pump.</p> |
