<p>Disclosed is a solvent recovery device (100) provided with a dirty liquid treatment tank (102) for storing dirty liquid (L) into which oil and a solvent (S) that are used for washing treatment are mixed, a heating medium storage unit (101) for storing a heating medium (105) for conducting heat into the dirty liquid treatment tank (102), a heating heater (104a) for heating the heating medium (105), a recovery path (111) for recovering vapor (G) of the solvent (S) from the dirty liquid treatment tank (102), a recovered liquid tank (115) for converting the vapor (G) of the recovered solvent (S) into condensate liquid and storing the liquid, and a cooling coil (116) for cooling the vapor (G) of the solvent (S) to a temperature at which the vapor (G) of the solvent (S) supplied to the recovered liquid tank (115) is converted into the condensate liquid, said solvent recovery device (100) being characterized by being provided with a rotating brush (103) which is rotated by an approximately horizontal rotating shaft part (103b) to thereby bury at least the lower part thereof in the dirty liquid (L) within the dirty liquid treatment tank (102) and lift the dirty liquid (L) to an upper space by the rotation, and a motor (113), a belt (114), and a gear part (106) which rotationally drive the rotating brush (103).</p> |
