Abstract
Provided is an apparatus for purifying materials, including: a raw water storage unit storing and supplying raw water; an evaporation unit evaporating the raw water supplied from the raw water storage unit; a heat exchange unit connected between the raw water storage unit and the evaporation unit, and condensing vapor (a material evaporated from the raw water) generated at the evaporation unit; and a recovery tank recovering the material condensed at the heat exchange unit, wherein the raw water supplied through the raw water storage unit is sent to the evaporation unit via the heat exchange unit, and the vapor evaporated at the evaporation unit is introduced into the recovery tank, after it is cooled and condensed at the heat exchange unit. A method for purifying materials using the apparatus is also provided. The apparatus and the method allow heat recycling, thereby reducing consumption of heat energy and electric energy, and prevent such problems as degradation of vacuum pump quality, overload or damages on some parts of the apparatus.
