HOT-AIR DESORPTION TYPE SOLVENT RECOVERING DEVICE

摘要

PURPOSE:To provide a solvent recovering device capable of uniformly heating a adsorbing material and relatively simply constituting an adsorbing tower, attaining high solvent removing efficiency and rapidly and uniformly rising the temp. of the adsorbing material even at the time of desorbing an organic solvent. CONSTITUTION:In a hot-air desorption type solvent recovering device for adsorbing the organic solvent by supplying an organic solvent containing gas to the adsorbing tower 1 and desorbing the organic solvent by indirectly heating the adsorbing tower 1, the adsorbing tower 1 has a continuous space through which a heating medium is passed and plural numbers of an adsorbing material packed tube 13 in which the adsorbing material 14 is packed are arranged at certain intervals in the continuous space.
