Solvent recovery apparatus

Abstract

There is provided a solvent recovery apparatus including: a cooling recovery device to which an untreated gas is supplied and which cools and condenses a solvent vapor contained in the untreated gas; an adsorption concentrator to which a primary-treated gas obtained by cooling and condensing the solvent vapor of the untreated gas in the cooling recovery device is supplied; an adsorption rotor that is provided in the adsorption concentrator and has an adsorption region in which uncondensed solvent vapor contained in the primary-treated gas is adsorbed and a desorption region in which a solvent vapor adsorbed in the adsorption region is desorbed; a desorption gas supply channel through which the untreated gas is supplied to the desorption region; and a desorption gas discharge channel through which a concentrated gas containing a solvent vapor desorbed from the desorption region is discharged to the cooling recovery device.
