<p>PROBLEM TO BE SOLVED: To provide a rotary gas adsorption concentration device which has solvent resistance, can use desorption air of high temperature of around 300°C and further can prevent leakage of the desorption air of such a high temperature by assembling relatively inexpensive materials in a simple structure.SOLUTION: A rotary gas adsorption concentration device has a honeycomb rotor which is rotatively driven and carries an adsorbent, and is divided into at least a desorption zone and an adsorption zone. Therein, a seal of an arcuate part of the honeycomb rotor has such a structure that a heat-resistant and solvent-resistant sheet 8 which is provided with a plurality of slits and has a sliding property and a sheet 9 having stretched rubber elasticity which is stacked on the sheet 8 are attached onto a rotor outer circumferential iron plate 2 in pile with a metal band 10 and are pressed against a seal flange 4 of casing. A part and all of the sheet 8 are made of glass fiber cloth-containing fluororesin sheet.</p> |
