<p>PURPOSE: To provide a solvent concentration apparatus which is small in size, simple in structure, and low in running costs (power expense). CONSTITUTION: Adsorption/desorption areas are installed which consist at least of adsorption layers 2A, 2B, space parts 6A, 6B having desorbed gas discharge parts 7A, 7B above the adsorption layers and treatment gas introduction parts 8A, 8B, and adsorption layer heating parts 3A, 3B below the adsorption layers, at least two sets of the adsorption/desorption areas are brought into surface- contact through an insulating wall 14, and a common space part 10 having a treatment gas introduction part 11 is located above each adsorption/desorption area. Besides, a solvent concentration apparatus has a common space part 12 having a treated gas discharge part 13 below each adsorption/desorption area, and parallel flow adsorption elements are preferably used for the adsorption layers.</p> |
