Abstract

An adsorption device includes disk-shaped adsorption module, and module holder for air insulation. The module holder includes a pair of end walls, a pair of connecting walls, a semi-cylindrical first shielding wall, and a semi-cylindrical second shielding wall. The pair of end walls are disposed on the adsorption modules of both end portions in a stacking direction with air distribution gaps sandwiched therebetween. The pair of connecting walls separate an outer circumferential portion of the plurality of air distribution gaps into an inflow region and an outflow region and connect outer circumferential edge portions of the pair of end walls. The first shielding wall shields 10 an outflow region outside the air distribution gap. The second shielding wall shields the inflow region outside the air distribution gap. The first shielding wall and the second shielding wall are disposed to alternately close the plurality of air distribution gaps in the stacking direction.
