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. 【課題】簡単な構造で、比較的安価な材料を組み合わせて、耐溶剤性で、かつ３００℃程度の高温の脱着空気を用いることが可能で、さらにそのように高温の脱着空気の漏れを防止可能な回転式ガス吸着濃縮装置を提供する。【解決手段】回転駆動され吸着剤を担持したハニカム状ロータを有し、少なくとも脱着ゾーンと吸着ゾーンとに分割する回転式ガス吸着濃縮装置において、ハニカム状ロータの円弧部分のシールを、複数のスリットを有する摺動性を備えた耐熱耐溶剤性シート８とその上に延伸したゴム弾性を有するシート９を重ねてロータ外周鉄板２に金属製バンド１０で取り付け、ケーシングのシールフランジ４に押し当てる構造とした回転式ガス吸着濃縮装置。シート８の一部及び全てがガラス繊維クロス入りフッ素樹脂シートよりなる、回転式ガス吸着濃縮装置【選択図】図２
