1. one kind is used for from extracting the device of solution separation and Extraction solution'"'"'s solute and product solvent, and wherein said device comprises:

  • First distillation tower, it comprises;

    First inlet, it is connected to and extracts source of solvent described extraction solution is introduced first end of described first distillation tower;

    First heat transfer unit (HTU), it is connected to second end of described first distillation tower, and described first heat transfer unit (HTU) has;

    the inlet that is connected to thermal energy source;

    And outlet, it is connected with described first distillation tower heat energy is introduced in described first distillation tower, so that at least a portion of the described extraction solution in described first distillation tower evaporation;

    First outlet, it is used for removing from described first distillation tower part of the evaporation of described extraction solution;

    AndAt least second column, it comprises;

    First inlet, it is connected to described extraction source of solvent described extraction solution is introduced first end of described second column;

    Second heat transfer unit (HTU), it is connected to second end of described second column, and described second heat transfer unit (HTU) has;

    inlet, its described first outlet that is connected to described first distillation tower is to be provided for the thermal energy source of described second column;

    And outlet, it is connected with described second column so that heat energy is introduced in the described second column, so that at least a portion of the described extraction solution in the after-fractionating chamber evaporation.
