According to the present invention, a purification device comprises: a solution storage unit configured to store a solution in which a solute and a solvent are mixed; a heating unit configured to heat the solution stored in the solution storage unit; a solute crystallization unit configured to make the heated solution flow, and lower the temperature of the solution to crystallize the solute; and a filter configured to separate the crystallized solute from the solution. The solution storage unit comprises a bath in which the solution is stored, and a contact blocking unit which blocks contact of the solution with air in the bath. |
