この発明は、被吸着物を吸着した炭素含有吸着剤と固形
熱担体との混合物の堆積を形成し、この堆積の中の固形
熱担体によって吸着剤を再生する反応器に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a reactor for forming a pile of a mixture of a carbon-containing adsorbent adsorbing an adsorbed substance and a solid heat carrier, and regenerating the adsorbent by the solid heat carrier in this pile. Regarding.
従来のこのような反応器はその構成要素として、反応容
器、反応容器の中に堆積を形成するために吸着剤および
熱担体をそれぞれ反応容器に送入するため反応容器の頂
部に同心に配置される２本の管、堆積から再生ずみ吸着
剤および熱担体を排出するため反応容器の底部に配置さ
れる排出口、並びに反応容器内で堆積の外部に保持され
るガス集積空間を通して堆積からガスを抜き出すため反
応容器の壁に配置されるガス出口を有する。Conventional such reactors include, as their components, a reaction vessel, an adsorbent and a heat carrier arranged concentrically at the top of the reaction vessel for delivering the adsorbent and heat carrier, respectively, into the reaction vessel to form a deposit within the reaction vessel. Gas is removed from the stack through two tubes, an outlet located at the bottom of the reaction vessel for discharging the regenerated adsorbent and heat carrier from the stack, and a gas collection space held outside the stack within the reactor vessel. It has a gas outlet located in the wall of the reaction vessel for withdrawal.
この反応器において吸着剤および熱担体が反応容器の頂
部の同心の管によって反応容器の中に供給されるから、
反応容器の中のこれらの堆積の上面は上向きに収束する
円錐面になる。In this reactor, the adsorbent and heat carrier are fed into the reaction vessel by concentric tubes at the top of the reaction vessel;
The upper surface of these deposits in the reaction vessel becomes an upwardly converging conical surface.
このような堆積は一般にばら楕円錐体と称せられる。Such deposits are commonly referred to as loose ellipsoids.
上述したような反応器では、堆積の中の見掛は比重の異
なる材料を混合しこの際に熱を伝達し同時にガスを堆積
の中から除去しなければならない。In reactors such as those described above, materials of apparently different specific gravities in the pile must be mixed, while heat is transferred and gases are removed from the pile at the same time.
堆積の中で熱分布を均等にしこれによって一様で完全な
吸着剤の再生を達成するためには、加熱すべき吸着剤を
固形熱担体例えば加熱砂の中でなるべく均等に分布させ
る必要がある。In order to achieve an even heat distribution within the pile and thus a uniform and complete regeneration of the adsorbent, it is necessary to distribute the adsorbent to be heated as evenly as possible in the solid heat carrier, e.g. heated sand. .
実際に示された難点は実質上、吸着剤の一部分はばら楕
円錐体の堆積に突当った場所で熱担体の中に沈まないと
いうことに存する。The difficulty presented in practice essentially consists in the fact that a portion of the adsorbent does not sink into the heat carrier at the point where it encounters the accumulation of rose ellipsoids.
これは第１には、ばら楕円錐体の表面における流動によ
って通常は比重の小さい吸着剤が比重の大きい熱担体の
中で浮上し易いさいうことに由来し、第２には、ばら楕
円錐体の表面における吸着剤の脱ガスの際に渦動ベッド
に類似した状態が生じてこれが送入材料を分離させ混合
を邪げることに存する。Firstly, this is because the flow on the surface of the rose elliptical cone causes the adsorbent, which normally has a low specific gravity, to easily float in the heat carrier with a high specific gravity. It consists in the fact that during the degassing of the adsorbent at the surface of the body a situation similar to a swirling bed occurs, which separates the feed materials and impairs their mixing.
その結果として、ばら楕円錐体のすその部分には、ばら
楕円錐体に突き当る際の統計的分布で期待されるよりも
多くの吸着剤が常に存することになる。As a result, there will always be more adsorbent at the base of the rose ellipsoid than would be expected from the statistical distribution of impingement on the rose ellipse.
この発明の目的は、公知の反応器を改善し、比重の小さ
い吸着剤と比重の大きい熱担体の均等な混合を達成し、
このことによって反応器の反応容器の容積を再生のため
に充分に使用できるようにすることにある。The purpose of this invention is to improve the known reactor and achieve uniform mixing of adsorbent with low specific gravity and heat carrier with high specific gravity,
The purpose of this is to ensure that the volume of the reaction vessel of the reactor can be used sufficiently for regeneration.
この目的はこの発明によれば、堆積の上面部分における
吸着剤および熱担体の材料流を制動するため、吸着剤お
よび熱担体を送入する同心の前記の２本の管の下方にお
いて上向きに収束する円錐面に実質的に沿うように配置
された１個または多くの同心の垂直な環状せきが配備さ
れる。The purpose of this, according to the invention, is to brake the material flow of adsorbent and heat carrier in the upper part of the pile so that it converges upwards below said two concentric pipes carrying the adsorbent and heat carrier. One or more concentric vertical annular weirs are provided that are arranged substantially along the conical surface of the conical surface.
この環状せきの詳しい配置および個数などは各環状せき
かばら楕円錐体の堆積の中に部分的に突・人するように
実験的に決定される。The detailed arrangement and number of these annular weirs are experimentally determined so that each annular weir partially protrudes into the stack of ellipsoidal cones.
すなわち、例えば何種類かの環状せきを用意しておいて
、予め製造された反応容器の中にこの環状せきを仮りに
固定配置し実際に吸着剤および熱担体またはそれらの等
何物を反応容器に送入しまたこれから排出し場合によっ
ては実際に再生作業をするような実験を行ない、その結
果に基いて環状せきの個数、直径、位置を調整するよう
にして有効な条件が決定できる。That is, for example, prepare several types of annular weirs, temporarily fix and place these annular weirs in a pre-fabricated reaction vessel, and actually place adsorbents, heat carriers, or other materials into the reaction vessel. Effective conditions can be determined by conducting experiments such as feeding and discharging the material, and in some cases actually performing regeneration work, and adjusting the number, diameter, and position of the annular weirs based on the results.
このようにすると驚くべきことには、せきによる飛散作
用によって、またせきによって生じる垂直流れ方向への
熱担体の偏向によって、比重の小さい吸着剤部分は熱担
体の中へ引込まれ、かつ熱担体と共に下向きに導かれる
。In this way, it is surprising that by the splashing action of the weir and by the deflection of the heat carrier in the vertical flow direction caused by the weir, the less specific adsorbent part is drawn into the heat carrier and together with it. guided downward.
比重の小さい部分と大きい部分とのこの混合は、個個の
吸着剤部分からの自発的なガス発生によって同時に起る
砂の流動とこれに伴なう全体の部分の「ゆすぎ」作用お
よび分別作用が混合作用をさまたげるにも拘わらず、発
生する。This mixing of the lower and higher specific gravity fractions is caused by the simultaneous movement of the sand by spontaneous gas evolution from the individual adsorbent fractions and the concomitant "rinsing" and fractionation effects of the entire fraction. occurs even though it hinders the mixing action.
混合の困難さに応じて１個または多くのせきが使用され
る。One or many weirs are used depending on the difficulty of mixing.
このせきは約１０Ｃｃｍばら積円積体から突出し約１０
−５０ｃｍばら楕円錐体に突入するように配置されるの
が望ましい。This weir protrudes from a bulk volume of approximately 10 Ccm and is approximately 10
-50 cm It is desirable to arrange it so that it may protrude into a 50 cm apart elliptical cone.
しかしながら上向きのせきの上限はせきを越える材料の
溢流（もしくは多量の溢流）を阻止すればよいのである
から重要な意味はない。However, the upper limit of the upward weir is of no significance since it is sufficient to prevent overflow (or large overflow) of material beyond the weir.
一方、混合作用に関してははら楕円錐体へ約１０−５０
ｃｍの深さでせきが突入することが特に有効である。On the other hand, regarding the mixing action, it is about 10-50 to the elliptic cone.
A weir plunge to a depth of cm is particularly effective.
堆積の側方に案内板をよろい戸状に配置すれば補助のガ
ス空間が形成され、これによって反応容器の空間の充分
な利用が達成される。By arranging guide plates in the form of shutters on the sides of the stack, an additional gas space is created, thereby achieving a good utilization of the space in the reaction vessel.
全ガス集積空間を隔壁によって多くの部分空間に分割し
そのおのおのにガス出口を設ければ、放出されるガスが
いくつかのガス成分に分離できる。By dividing the entire gas accumulation space into many subspaces by partition walls and providing a gas outlet in each subspace, the released gas can be separated into several gas components.
