Description

【０００１】
【発明の属する技術分野】
本発明は、空気を冷媒として圧縮し、高温高圧となった圧縮空気を常温付近まで冷却した後、膨張機を介して低温空気を得るようにした冷凍サイクルにおいて、前記圧縮排熱の有効利用を図る高効率吸脱着システムを使用した冷却装置に関する。
【０００２】
【従来の技術】
従来の空気冷凍サイクルを利用した冷却装置は、作動媒体となる空気を流路に沿って圧縮機、放熱用熱交換器、水蒸気分離装置、膨張機を配設し、原動機で圧縮機、膨張機を運転し、前記圧縮機で断熱圧縮を行い、放熱用熱交換器で周囲温度まで降温させ、水蒸気分離装置で水分を除去し、乾燥空気を膨張機で断熱圧縮を行い、低温空気を得るようにしたものである。
【０００３】
ところが、前記水蒸気分離装置は、除湿器等が使用され、放熱器で降温させた低温高圧空気を完全な乾燥気体にすることは無理であった。そのため、本願発明者等により、特願平１０−２１６７０７号には断熱膨張前の高圧空気を常に乾燥状態に維持する必要から、前記除湿器には吸着器の使用の提案がされている。
【０００４】
上記提案においては、一対の吸着器を使用する構成とし、圧縮機からの高温高圧空気を吸着済みの吸着器内を貫流させて再生させ、ついで放熱用熱交換器からの断熱膨張前の高圧空気を他の再生済みの吸着器内に貫流除湿させ、一方の吸着器を再生させるとともに他方の吸着器により除湿を行い、再生と除湿とを交互に切り替え可能の構成としたものである。
【０００５】
【発明が解決しようとする課題】
しかし、前記吸着剤の再生は単に圧縮機からの高圧空気による加熱を利用したもので、高真空下で行なわれたものでなく、また除湿は吸着剤の吸着時の反応熱の除去のもとに行なわれたものではないため、吸着剤の十分な再生及び膨張機への導入空気は完全に乾燥された低温空気が導入されないため、従来の空気冷却器では単なる顕熱冷房のみにたより、動作係数の低い状態での使用に甘んじている状況である。
【０００６】
本発明は上記問題点に鑑みなされたもので、空気を冷媒として圧縮し、高温高圧となった圧縮空気を常温付近まで放熱器により冷却した後、膨張機を介して低温空気を得るようにした冷凍サイクルにおいて、圧縮機より放熱器までの流路において吸着剤の脱着再生ゾーンを設け、放熱器以後の膨張機に至る流路において吸着ゾーンを持つ回転体による高効率吸脱着システムを設け、動作係数の改善を図り空気の顕熱のみならず蒸発潜熱の利用を可能とした冷却装置の提供を目的としたものでる。
【０００７】
【課題を解決するための手段】
そこで、本発明の冷却装置は、
空気を媒体として圧縮機、放熱器、膨張機の順よりなる流路を介して低温空気を形成して、冷却用熱負荷を冷却する空気冷却サイクルにおいて、
前記圧縮機と膨張機との間に吸着剤を内蔵する吸着回転体を持つ密閉回転除湿機を設け、介在する放熱器の手前に前記回転除湿機の再生ゾーンを設け、該ゾーンで圧縮機の吐出ガスを加熱流体として使用して、内蔵する吸着剤の真空脱着をさせ、
前記放熱器と膨張機との間に前記密閉回転除湿機の吸着ゾーンを設け、前記放熱器を経由した低温ガスを前記再生脱着した吸着剤により冷却流体の冷却のもとに吸着させ、
前記吸着剤の連続的脱吸着とともに吐出ガスの連続的排熱放出と乾燥とを可能にする構成としたことを特徴とする。
【０００８】
前記請求項１記載の発明は、空気を媒体とする圧縮機、放熱器、放膨張機の順よりなる流路において、圧縮機と膨張機との間に吸着剤を充填した吸着回転体を持つ密閉回転除湿機は再生ゾーンと吸着ゾーンを持ち、前記再生ゾーンと吸着ゾーンの間に放熱用熱交換器を設けるようにしたもので、圧縮機を出た高温高圧の吐出ガスは、前記再生ゾーンの回転吸着器の真空脱着流路に隣接付設させた加熱流体流路を介して吸着剤を加熱して、真空密閉下で吸着剤の再生脱着を効率的に行なわせる。ついで、再生ゾーンを出た吐出ガスは放熱器で常温の低温ガスに降温させ、低温ガスとなって前記密閉回転除湿機のの吸着ゾーンに導入され、さきに再生ゾーンで再生させた吸着剤を充填した吸着回転体の吸着流路に導入される。そして、前記吸着流路に隣接付設した冷却流体流路を介して吸着用冷熱を供給して吸着反応熱を抑え高効率の吸着を可能としている。
斯くして、圧縮機を出た吐出ガスは、前記再生ゾーン及び吸着ゾーンを有する密閉回転除湿機により、その排熱の連続的放出により吸着剤の効率的真空再生と低温ガスの完全乾燥を可能とし、続く膨張機により冷熱を得て顕熱のみならず蒸発潜熱を冷却負荷に与えることができる。
【０００９】
また、請求項１記載の密閉回転除湿機の再生ゾーンには、圧縮機吐出ガスの供給機構と真空吸引機構とを設け、吸着ゾーンには放熱器からの低温ガスの供給機構と冷却流体の供給機構とを設け、
前記吸着回転体は両端の対向位置には回転体を前記二分割ゾーンに分割する二分割固定シール板を設けるとともに、内筒及び外筒のいずれかに吸着剤を充填した二重円筒構造体を法線方向の貫通隔壁により前記二分割固定シール板より狭い幅で内外２連状に分割し得られた、多分劃２連流路により構成し、
前記二分割固定シール板を経由する毎に前記多分劃２連流路に流出入する流体の切り替えを順次行なう構成としたことを特徴とする。
【００１０】
前記請求項２記載の発明により、請求項１記載の密閉回転除湿機の再生ゾーン及び吸着ゾーンは、吸着回転体の回転に対し、常に定位置に保持される。そのため、再生ゾーンには、圧縮機吐出ガスの供給機構と真空吸引機構とを設け、吸着ゾーンには放熱器からの低温ガスの供給機構と冷却流体の供給機構とを設ける構造とし、
吸着回転体に設けられ吸着剤を充填した再生／吸着用流路は、再生ゾーンでは吐出ガスの吸着剤加熱のための流入と真空処理を受け再生機構として機能させ、吸着ゾーンでは低温ガスの流入と冷却流体の流入を受け吸着機構として機能させ、且つその機能の切り替えは回転体の両端の対向位置に設けられた二分割固定シール板により行なうようにしたものである。
そのため、回転体は内筒及びそれに隣接する外筒よりなる二重円筒体で形成しその何れかに吸着剤を充填する構造にしてある。そして、該二重円筒体を法線方向に等分分劃して前記二分割固定シール板より小さい幅を持つ内筒、外筒の２連分劃流路よりなる複数の多分劃２連流路を形成する構造にしてある。
【００１１】
また、請求項２記載の多分劃２連流路は、
再生ゾーンにおいては、二重円筒体の内外筒の何れか一方に形成された真空脱着用の多分劃流路と、該流路に隣接した他方に設けた加熱流体用の多分劃流路とより構成し、
吸着ゾーンにおいては、前記二重円筒体の内外筒の前記真空脱着流路と同じ側に形成され低温ガスが流入する吸着用の多分劃流路と、該流路に隣接した他方側に設けた冷却流体用の多分劃流路とより構成したことを特徴とする。
【００１２】
前記請求項３記載の発明により、
請求項２に記載の発明により構成された多分劃２連流路は、前記二分割固定シール板を境にして再生機構として機能し、または吸着機構として機能する。
即ち、再生ゾーンにおいては、二重円筒体の内外筒の何れか一方に吸着剤を充填し、充填した吸着剤の脱着再生を真空下で行なうようにした真空脱着用の多分劃流路と、該流路に隣接した他方に設けた加熱流体用の多分劃流路とより構成し、
吸着ゾーンにおいては、前記二重円筒体の内外筒の前記真空脱着流路と同じ側に充填され且つ再生ゾーンで既に再生されている吸着剤の中に低温ガスを流入させ低温ガスの水分を吸着させるための吸着用多分劃流路と、該流路に隣接した他方側に設けた冷却流体用の多分劃流路とにより構成としてある。
【００１３】
また、請求項１記載の密閉回転除湿機の吸着回転体は、
吸着回転体の両端の対向位置に設けた二分割固定シール板による被覆端面以外の回転体両端の左側端面には真空脱着流路と加熱流体流路の端面を覆う扇形固定シール板を設け、右側端面には吸着流路と冷却流体流路の端面を覆う扇形固定シール板を設け、
前記各扇形固定シール板の端面接触側に前記回転体の内外筒のそれぞれに形成された流路の出入り口を結ぶ連絡凹路を設ける構成とし、
前記真空脱着流路の両端出口の連絡凹路には脱着蒸気を吸引する真空空気の吸引口を設け、加熱流体流路の両端出口の連絡凹路には加熱流体である吐出ガスの出入り口を設け、前記吸着流路の両端出口の連絡凹路には被吸着流体の低温ガスの出入口を設け、冷却流体流路の両端出口の連絡凹路には冷却流体の出入口を設ける構成としたことを特徴とする。
【００１４】
前記請求項４記載の発明により、
前記内筒、外筒の２連分劃流路よりなる多分劃流路が再生ゾーンにあるときは、外部より常に加熱流体の供給を受けるとともに真空ポンプによる吸引を受ける必要があり、また、吸着ゾーンにある時は外部より常に低温ガスと冷却流体の供給を受ける必要がある。
そのため、二重円筒体を形成する吸着回転体の端面の両端の回転中心を過る対向位置に設けた二分割固定シール板による被覆端面以外の両端の左側の端面には真空脱着流路と加熱流体流路の端面を覆う扇形固定シール板を設け、右側端面には吸着流路と冷却流体流路の端面を覆う扇形固定シール板を設け、前記各扇形固定シール板の端面接触側に前記二重円筒体の内外筒のそれぞれに形成された流路の出入り口を結ぶ連絡凹路を設け、且つそれぞれの扇形固定シール板に設けた連絡凹路には被覆するそれぞれの流路への流体の出入口または真空吸入口を設ける構造にしてある。
【００１５】
また、 請求項１記載の吸着回転体は、
隣接する内筒、外筒よりなる回転可能の一体構造の気密構造で形成され、内筒と外筒との隣接部材は熱交換可能の高伝熱性素材で構成したことを特徴とする。
【００１６】
前記請求項５記載の発明は、請求項１記載の密閉回転除湿機の吸着回転体の構造について記載したもので、該回転体を構成する内筒と外筒は、再生時においてその何れかが内蔵する吸着剤を真空脱着するため、気密性を保持するため一体構造の気密構造にしてある。
また、一体構造の内筒及び外筒は、それぞれ一方に充填された吸着剤を他方を流動する加熱流体により間接加熱をするか、または冷却流体により間接冷却をするため、内外筒は伝熱特性の高い素材を使用する構成にしてある。
【００１７】
また、請求項１の吸着回転体は、再生ゾーンにおいては、吸着剤の脱着真空流路を外筒側に設け吸着剤を充填する構造とし、加熱流体流路は内筒側に設ける構成とし、
また、吸着ゾーンにおいては、吸着流路を外筒側に設け吸着剤を充填する構造とし、冷却流体流路は内筒側に設ける構成としたことを特徴とする。
【００１８】
【発明の実施の形態】
以下、本発明を図に示した実施例を用いて詳細に説明する。但し、この実施例に記載される構成部品の寸法、材質、形状、その相対配置などは特に特定的な記載が無い限り、この発明の範囲をそれのみに限定する趣旨ではなく単なる説明例に過ぎない。
なお、従来の部品と同一の部品に対しては、本発明に於いては従来部品に使用した符号と同一の符号を使用してある。
図１は、本発明の冷却装置の概略の構成を示す模式図で、図２は図１の密閉回転除湿機の一実施例の概略の構成を示す断面図で、図３は図２の密閉回転除湿機の吸着回転体の端面と二分割固定シール板及び扇形固定シール板との間の関係位置を示す図であり、図４は図２の密閉回転除湿器の左側回転軸芯を含む分解斜視図である。
【００１９】
図１に示すように、本発明の冷却装置は、圧縮機５１と膨張機５２と放熱器５３と密閉回転除湿機１０とより構成し、空気を媒体とした圧縮機５１、放熱器５３、膨張機５２の順よりなる工程を介して低温空気を形成して、冷却負荷５０を冷却する空気冷却サイクルにおいて、前記放熱器５３の前後に再生ゾーン１０ａと吸着ゾーン１０ｂを持つ密閉回転除湿機１０を設けたもので、図５に示す圧縮機５１と放熱器５３との間に再生モードの吸着器５４を設け、放熱器５３と膨張機５２との間に吸着モードの吸着器５５を設けた従来の空気冷却器に比較して高効率の吸脱着を可能にし、顕熱冷却のみならず潜熱冷却を可能にしている。
【００２０】
図２には図１の密閉回転除湿機１０の一実施例についての概略の構成が示してある。
上記実施例においては、吸着回転体１１の外筒に吸着剤を充填し放熱器５３の前の再生ゾーン１０ａにおいては圧縮機５１からの高温高圧の吐出ガスを加熱流体として再生加熱に使用して吸着剤の真空脱着を行い、ついで吸着ゾーン１０ｂにおいては放熱器５３を経由した低温ガスを再生済みの吸着剤に導入して冷却流体による吸着反応熱を抑えたなかで完全除湿を行い、後段の膨張機５２へ導入するようにしたものである。
なお、図２に示す断面図は、再生ゾーン１０ａとその対向位置にある吸着ゾーン１０ｂの中心を通る載断面による断面図を示してある。そのため、中心軸芯上に位置する二分割固定シール板は記載してない。
図に見るように、密閉回転除湿機１０は、本体２０とブラケット２１ａ、２１ｂと吸着回転体１１と該回転体の回転する両端の端面に気密状に接触可能とする図示してない二分割固定シール板と扇形固定シール板１３ａ、１３ｂ、１４ａ、１４ｂとより構成する。
【００２１】
前記本体２０とブラケット２１ａ、２１ｂは密閉状容器を形成し、該ブラケット２１ａ、２１ｂは回転中心に対し左右の対称位置（図３、図４では上下対称位置）にそれぞれ２分割固定シール板１２ａ、１２ｃと１２ｂ、１２ｄを装着し、また、上下対称位置（図３、図４では左右対称位置）にそれぞれ扇形固定シール板１３ａ、１４ａと１３ｂ、１４ｂを装着してある。
前記二分割固定シール板は、当接接触する左右の２連分劃流路を閉鎖してそれにより分割された上側の真空脱着流路２９とそれに隣接する加熱流体流路３３よりなる２連分劃流路４２ｃを含む２連分劃流路群を再生ゾーンに置き、（図４参照）
また、下側の吸着流路３０とそれに隣接する冷却流体流路３２よりなる２連分劃流路４３ｃを含む２連分劃流路群を吸着ゾーンに置き、（図４参照）
前記再生ゾーン１０ａにおいては、高温吐出ガスによる間接加熱とバキュームポンプ１０ｃによる真空脱着とにより内蔵する吸着剤３１の連続再生を可能とさせ、吸着ゾーン１０ｂにおいては、先に加熱に使用した吐出ガスを放熱器５３を介して降温させた低温ガスの吸着流路３０への導入と冷却流体による間接冷却とにより吐出ガスである低温ガスの連続的除湿を可能としている。
【００２２】
即ち、前記２連分劃流路群に再生機能または吸着機能を機能させるため、再生ゾーン１０ａにおいては、圧縮機５１の吐出ガスの供給及びバキュームポンプ１０ｃが設けられ、前記高温高圧の吐出ガスは前記加熱流体流路３３に導入され、隣接する外筒側の真空脱着流路２９に充填した吸着剤を間接加熱し脱着再生熱を与えるとともに、脱着した水分をバキュームポンプ１０ｃにより吸引させ外部へ放出させている。
そして、加熱流体流路３３に導入され吸着剤に再生熱を与え圧縮機５１の排熱の有効利用を図った吐出ガスは、放熱器５３に導入降温され、常温の低温ガスとして吸着ゾーン１０ｂに送り除湿される。
また吸着ゾーン１０ｂにおいては、前記放熱器５３を経由降温した被吸着ガスである低温ガスが上記のように用意され、吸着反応熱を吸収する冷却空気又は冷却水よりなる冷却流体も別途用意され、前記低温ガスは吸着流路３０に導入され、該流路に充填されている再生済みの吸着剤によりその水分を吸着除湿させる。なおその際発生する吸着反応熱は隣接する冷却流体流路３２に導入された冷却流体により冷却され吸着効率を上げるようにしてある。
【００２３】
図３には、図２の密閉回転除湿機の吸着回転体の両端の端面と二分割固定シール板及び扇形固定シール板との間の関係位置が示してあり、図４には、図２の密閉回転除湿器の左側軸芯を含む分解斜視図が示してある。
図３、図４に見るように、回転する吸着回転体１１のある瞬間において、回転体の前後の両端面の上側２連分劃流路４１ａを二分割固定シール板１２ａ、１２ｂにより密封閉鎖され、下側２連分劃流路４１ｂを二分割固定シール板１２ｃ、１２ｄにより密封閉鎖されると、残る略左半分の２連分劃流路４２ａ、４２ｂ、４２ｃ、４２ｄ、４２ｅは再生ゾーンとして機能され、右半分の２連分劃流路４３ａ、４３ｂ、４３ｃ、４３ｄ、４３ｅは吸着ゾーンとして機能されることになる。
この状態は、吸着回転体の１１の回転方向が例えば右回りの場合は、該回転体が等分劃してある２連分劃流路の１個を経過する毎に、前記再生ゾーン及び吸着ゾーンは左にずれることになる。
なお、前記二分割固定シール板の幅は等分劃してある２連分劃流路の幅より僅か大きく設定して分劃した区劃毎に確実にシールできるようにしてある。
また、前記分劃した２連分劃流路の幅はある程度小さい方が機能の切り替えは円滑且つ効率的に行なうことができる。
【００２４】
また、図３に見るように、扇形固定シール板１３ａ、１３ｂは前記二分割固定シール板により分割された左側の流路群への所用流体の分散導入と排出を可能とすべく気密状に設けたもので、１４ａ、１４ｂは同じく右側流路群への所用流体の分散導入と排出を可能とすべく気密状に設けたもので、そのため、図に見るように扇形固定シール板１３ａ、１３ｂや１４ａ、１４ｂにはそれぞれ吸着回転体１１の端面との接触面に連絡凹路１５ａ、１６ａ、１５ｂ、１６ｂ、１７ａ、１７ｂ、１８ａ、１８ｂが設けられ、各連絡凹路には真空吸入口３４、吐出ガスの出入り口３６ａ、３６ｂ、低温ガスの出入り口３７ａ、３７ｂ、冷却流体の出入り口３５ａ、３５ｂを設け、所用の機能を連携する各流路に与えるようにしてある。
【００２５】
なお、吸着回転体１１は、図４に示す分解斜視図に見るように内筒と外筒とを一体構造とした気密二重円筒構造体で形成され、その端面に見るように法線方向の貫通隔壁により前記二分割固定シール板より狭い幅で内外２連分劃流路４１ａ、４１ｂ、４２ａ〜４２ｅ、４３ａ〜４３ｅよりなる多分劃２連流路により構成し、隣接する流路間において熱交換する構成にしてあるため、外筒と内筒の隣接部材は特に高伝熱性素材を使用する構成にしてある。

BACKGROUND OF THE INVENTION
In the refrigeration cycle in which low-temperature air is obtained through an expander after compressing air as a refrigerant and cooling the compressed air that has become high temperature and high pressure to near normal temperature, the effective use of the compressed exhaust heat is achieved. The present invention relates to a cooling device using a high-efficiency adsorption / desorption system.
[0002]
[Prior art]
A conventional cooling device using an air refrigeration cycle is provided with a compressor, a heat-dissipating heat exchanger, a water vapor separator, and an expander along the flow path of air serving as a working medium. So that the adiabatic compression is performed with the compressor, the temperature is lowered to the ambient temperature with the heat exchanger for heat dissipation, the moisture is removed with a water vapor separator, and the dry air is adiabatic with the expander to obtain low-temperature air. It is a thing.
[0003]
However, a dehumidifier or the like is used for the water vapor separator, and it is impossible to make the low-temperature and high-pressure air cooled by the radiator into a completely dry gas. For this reason, the inventors of the present application have proposed to use an adsorber as the dehumidifier because Japanese Patent Application No. 10-216707 needs to always maintain high-pressure air before adiabatic expansion in a dry state.
[0004]
In the above proposal, a pair of adsorbers are used, and the high-temperature high-pressure air from the compressor is regenerated by flowing through the adsorbed adsorber, and then the high-pressure air before adiabatic expansion from the heat-dissipating heat exchanger. In the other regenerated adsorbers, one adsorber is regenerated and dehumidified by the other adsorber, and regeneration and dehumidification can be switched alternately.
[0005]
[Problems to be solved by the invention]
However, the regeneration of the adsorbent is simply performed by heating with high-pressure air from a compressor, not performed under high vacuum, and dehumidification is based on the removal of heat of reaction during adsorption of the adsorbent. Because it was not carried out in this way, sufficient regeneration of the adsorbent and air introduced into the expander was not introduced with completely dried low-temperature air, so conventional air coolers operate more than just sensible heat cooling. It is a situation that is unsatisfactory for use in a low coefficient state.
[0006]
The present invention has been made in view of the above-described problems. After compressing air as a refrigerant and cooling the compressed air that has become high temperature and high pressure to near room temperature with a radiator, low temperature air is obtained through an expander. In the refrigeration cycle, an adsorbent desorption / regeneration zone is provided in the flow path from the compressor to the radiator, and a high-efficiency adsorption / desorption system using a rotating body with an adsorption zone is provided in the flow path from the radiator to the expander. The purpose is to provide a cooling device that can improve the coefficient and use not only sensible heat of air but also latent heat of vaporization.

The cross-sectional view shown in FIG. 2 is a cross-sectional view of a loading cross section passing through the center of the regeneration zone 10a and the adsorption zone 10b at the opposite position. Therefore, the two-part fixed sealing plate located on the central axis is not described.
As shown in the figure, the hermetic rotary dehumidifier 10 is fixed in two parts (not shown) that allows airtight contact with the main body 20, the brackets 21a and 21b, the adsorption rotator 11, and the end surfaces of the rotating ends of the rotator.

The two-part fixed sealing plate closes the left and right two-part split flow passages in contact with each other and is divided into two pieces consisting of an upper vacuum desorption passage 29 and a heating fluid passage 33 adjacent thereto. A group of two continuous dredging channels including the dredging channel 42c is placed in the regeneration zone (see FIG. 4).
Further, a group of double split flow channels including a double split flow channel 43c including the lower adsorption flow channel 30 and the cooling fluid flow channel 32 adjacent thereto is placed in the adsorption zone (see FIG. 4).
In the regeneration zone 10a, the built-in adsorbent 31 can be continuously regenerated by indirect heating with a high-temperature discharge gas and vacuum desorption by a vacuum pump 10c. In the adsorption zone 10b, the discharge gas previously used for heating is used. The dehumidification of the low temperature gas, which is the discharge gas, is enabled by the introduction of the low temperature gas, which has been cooled down via the radiator 53, into the adsorption flow path 30 and the indirect cooling by the cooling fluid.
[0022]
That is, in order to cause the regeneration function or the adsorption function to function in the double split channel group, in the regeneration zone 10a, a discharge gas supply of the compressor 51 and a vacuum pump 10c are provided, and the high temperature and high pressure discharge gas is The adsorbent introduced into the heating fluid channel 33 and filled in the vacuum desorption channel 29 on the adjacent outer cylinder side is indirectly heated to give desorption regeneration heat, and the desorbed water is sucked by the vacuum pump 10c and released to the outside.

The low-temperature gas is introduced into the adsorption channel 30 and the moisture is adsorbed and dehumidified by the regenerated adsorbent filled in the channel. The adsorption reaction heat generated at this time is cooled by the cooling fluid introduced into the adjacent cooling fluid channel 32 to increase the adsorption efficiency.
[0023]
FIG. 3 shows the relative positions between the end faces of both ends of the adsorption rotating body of the hermetic rotary dehumidifier of FIG. 2 and the two-part fixed seal plate and the fan-shaped fixed seal plate. An exploded perspective view including the left axis of the hermetic rotary dehumidifier is shown.

When the lower two-part split flow passage 41b is hermetically closed by the two-part fixed sealing plates 12c, 12d, the remaining two-part split flow passages 42a, 42b, 42c, 42d, 42e on the left half are used as regeneration zones. The two half-split channels 43a, 43b, 43c, 43d, and 43e in the right half function as an adsorption zone.
In this state, when the rotation direction of the adsorption rotator 11 is, for example, clockwise, the regeneration zone and the adsorption each time one of the two continuous dividing channels in which the rotator is equally divided passes. The zone will shift to the left.
Note that the width of the two-part fixed sealing plate is set to be slightly larger than the width of the equally divided two-part dividing flow path so as to ensure sealing for each divided section.
The function switching can be performed smoothly and efficiently when the divided double dividing flow path has a relatively small width.
[0024]
Further, as shown in FIG. 3, the fan-shaped fixed seal plates 13a and 13b are provided in an airtight manner so that the required fluid can be dispersed and introduced into and discharged from the left channel group divided by the two-divided fixed seal plate. 14a and 14b are provided in an airtight manner so that the required fluid can be dispersed and introduced into and discharged from the right channel group, and as shown in the figure, the fan-shaped fixed seal plates 13a and 13b and 14a and 14b are respectively provided with connecting recesses 15a, 16a, 15b, 16b, 17a, 17b, 18a and 18b on the contact surface with the end face of the suction rotating body 11, and each connecting recess has a vacuum suction port 34, The discharge gas inlet / outlet ports 36a and 36b, the low temperature gas inlet / outlet ports 37a and 37b, and the cooling fluid inlet / outlet ports 35a and 35b are provided, and the desired functions are provided to the associated flow paths.

The penetrating partition wall is constituted by a multi-split double continuous flow path that is narrower than the two-part fixed sealing plate and is composed of inner and outer double split flow paths 41a, 41b, 42a to 42e, 43a to 43e, and heat is generated between adjacent flow paths. Since it is configured to be replaced, the adjacent member between the outer cylinder and the inner cylinder is configured to use a particularly highly heat-conductive material.
Each time it passes through the two-divided fixed sealing plate, the fluid that flows into and out of the two-way continuous flow channel is sequentially switched.
[0026]
When assembling, as seen in the exploded perspective view including the left axis shown in FIG. 4, while inserting the suction rotating body 11 having a freely slidable outer diameter into the cylindrical structure forming the main body 20, A two-part fixed sealing plate 12a is mounted on the upper concave portion of the inner surface of the bracket 21a with a spring 22a as shown by an arrow A, and a fan-shaped fixed sealing plate 13a is held with a spring 23a and 23a as shown by arrows B and B.
