To provide an organic solvent gas treatment device, which facilitates the reuse of an organic solvent because of a low water content in an organic solvent recovered from organic solvent gases generated from factories and the like.
The organic solvent gas treatment device can lower the water content of a condensed organic solvent, enhance the cooling effect in a purge zone 3, and thus improve adsorption ability by dividing an adsorption rotor 1 to at least an adsorption zone 2, a desorption zone 4, and the purge zone 3, causing desorption air to pass through a cooling and dehumidifying means 5 and then through the purge zone 3, heating the desorption air that has passed through the purge zone 3 with a heater 6, causing the heated air to pass through the desorption zone 4, and then condensing an organic solvent contained in gases that have passed through the desorption zone 4 with a condenser 7.
