US 10,478,828 B2 · Solvent separation method and solvent separation apparatus

Abstract

Provided is a solvent separation method and a solvent separation apparatus that make it possible to efficiently retrieve the thermal energy possessed by an exhaust atmosphere released in a solvent-removal step to suppress reductions in a temperature of the exhaust atmosphere. In the solvent separation method and the solvent separation apparatus, a vaporized solvent is removed from a gas while heat exchange between the gas within a condensation part and the gas within a dust-collection part is conducted by using a heat exchange part that is placed between the condensation part that introduces the gas into a first direction and the dust-collection part that introduce the gas into a second direction opposite to the first direction the gas discharged from a downstream side of the condensation part.

Dependent claims

A solvent separation apparatus, comprising:

a condensation part that a gas including a vaporized solvent is introduced into in a first direction, and in which an electric field is applied to the gas to condense the vaporized solvent, and the gas is discharged therefrom to a downstream side of said condensation part;
a dust-collection part that the gas discharged from the downstream side of the condensation part is introduced into in a second direction opposite to the first direction, and in which an electric field is applied to the gas to separate the vaporized solvent;
and
a heat-exchange part that is placed between the condensation part and the dust-collection part, and that provides heat exchange between the gas within the condensation part and the gas within the dust-collection part.
