MEMBRANE DISTILLATION AND FRACTIONATION UNIT

Japanese Patent JP2016131929

A

PROBLEM TO BE SOLVED: To provide a fractionation unit which has a favorable fractionation efficiency using a membrane distillation apparatus and is capable of efficiently fractionating a treatment objective liquid component simply and inexpensively.SOLUTION: A fractionation system 1 for a treatment objective liquid W is configured by connecting three stages of membrane distillation apparatuses in series. A first membrane distillation apparatus 2 is equipped with a hydrophobic porous membrane 5 to form a first raw water chamber 6 and a first condensation chamber 7 through which the treatment objective liquid W circulates by sandwiching this hydrophobic porous membrane 5. A second membrane distillation apparatus 3 is equipped with a hydrophobic porous membrane 8 to form a second raw water chamber 9 and a second condensation chamber 10 through which a primary distillation liquid W1 circulates by sandwiching this hydrophobic porous membrane 8. A third membrane distillation apparatus 4 is equipped with a hydrophobic porous membrane 11 to form a third raw water chamber 12 and a third condensation chamber 13 through which a secondary distillation liquid W2 circulates by sandwiching this hydrophobic porous membrane 11.SELECTED DRAWING: Figure 1
