Abstract: Provided is a desalination device using a solvent extraction method, comprising: a first mixing tank composed of a feed water inlet into which feed water comprising salt ions and water molecules flows, a first solvent inlet into which a first solvent selectively reacting more with the water molecules than with the salt ions flows, a first mixing tank body in which the feed water and the first solvent are mixed so as to form a mixed water, and a mixed water outlet through which the mixed water is discharged; a first separation tank composed of a mixed water inlet which communicates with the mixed water outlet so that the mixed water flows therein, a first separation tank body in which brine containing salt ions of the feed water and first treatment water formed from mixing the water molecules of the feed water and the first solvent of the mixed water are separated by layer, and a first treatment water outlet through which the first treatment water is discharged; a second mixing tank composed of a first treatment water inlet which communicates with the first treatment water outlet so that the first treatment water flows therein, a second solvent inlet into which a second solvent selectively reacting more with the first solvent than with the water molecules of the treatment water flows, a second mixing tank body in which the first treatment water and the second solvent are mixed so as to form second treatment water, and a second treatment water outlet through which the second treatment water is discharged; and a second separation tank composed of a second treatment water inlet which communicates with the second treatment water outlet so that the second treatment water flows therein, a second separation tank body in which the water molecules of the first treatment water and a composite solvent formed from mixing the first solvent of the first treatment water and the second solvent of the second treatment water are separated by layer, and a fresh water outlet through which fresh water composed of the water molecules is discharged.
