  • Patent number: 10376831
    Abstract: Provided is a solvent separation method and a solvent separation apparatus in which a vaporized solvent is collected at one internal side of a solvent separation unit by attracting the vaporized solvent based on electric field, while the vaporized solvent is prevented from coming into contact with electrodes, and the collected solvent is discharged from the solvent separation unit. Different electric fields are alternately applied to a pair of first electrodes and a pair of second electrodes present at predetermined locations inside a tetragonal tubular solvent separation unit to attract a vaporized solvent toward the second electrodes. Thus, the vaporized solvent is collected in a space between the second electrodes inside the solvent separation unit, and the collected solvent is discharged from the solvent separation unit, together with a portion of the exhaust atmosphere present around the collected solvent.
    Type: Grant

  • Patent number: 10040025
    Abstract: To provide a solvent separator for purifying an exhaust atmosphere efficiently in solvent removal from the exhaust atmosphere containing a vaporized solvent by the heating exhausted from an exhaust generator, so that the vaporized solvent does not slip through an electrode for collecting the solvent and is positively led to the electrode. An electrode is arranged in a first wall surface of a casing of a solvent separation unit having a circular cylindrical shape, thereby inducing a vaporized solvent in an exhaust atmosphere to the electrode by a fan and discharging the solvent to the outside of the separator with part of the peripheral exhaust atmosphere while attracting the solvent to the electrode by an electric field of the electrode.
