PROBLEM TO BE SOLVED: To prevent the clogging of a spray nozzle, and further, to simplify an apparatus of volatilizing a solvent.SOLUTION: In a solvent separator 10, while retaining the pressure of solid component-concentrated slurry in the nozzle orifice of a spray nozzle to the vapor pressure of a solvent or higher, the solid component-concentrated slurry is sprayed from the spray nozzle into a flush tank whose pressure is set below the saturated pressure of the solid content-concentrated slurry, thus the solvent is evaporated and separated from the solid component-concentrated slurry. |
