【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、吸着剤を用いた物質濃縮装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a substance concentration device using an adsorbent.
従来吸着剤を用いた物質濃縮装置では、吸着プロセスで
発熱反応が起こり、吸着剤及びその近傍で温度上昇が起
こる。一方、脱着プロセスでは吸熱反応が起こり、吸着
剤及びその近傍で温度降下が起こる。にもかかわらず、
これらの熱的な吸着阻害要因を簡便な方法で解決しない
ままであった。In conventional substance concentrators using adsorbents, an exothermic reaction occurs during the adsorption process, causing a temperature increase in the adsorbent and its vicinity. On the other hand, in the desorption process, an endothermic reaction occurs, causing a temperature drop in the adsorbent and its vicinity. in spite of,
These thermal adsorption inhibiting factors have not yet been solved by a simple method.
一般に、物質が吸着剤に吸着する際には低温であればあ

ろが、一般に、吸着に伴い発熱反応が起こり、この為、
吸着剤及び吸着剤近傍に温度上昇が起こる。即ち、反応
が進むにつれて、物質の吸着剤に対する吸着が温度上昇
によって阻害される方向に向かうと言える。Generally, when a substance is adsorbed on an adsorbent, the lower the temperature, the greater the amount of substance adsorbed per unit amount of adsorbent. However, in general, an exothermic reaction occurs with adsorption, and because of this,
A temperature rise occurs in the adsorbent and in the vicinity of the adsorbent. In other words, it can be said that as the reaction progresses, the adsorption of the substance onto the adsorbent tends to be inhibited by the rise in temperature.
一方、物質が吸着剤から脱着する際には一般に吸熱反応
が起こる。この為、吸着剤及び吸着剤近傍に温度降下が
起こる。即ち、反応が進むにつれて、物質の吸着剤に対
する脱着が温度降下によって阻害される方向に向かうと
言える。On the other hand, when a substance is desorbed from an adsorbent, an endothermic reaction generally occurs. For this reason, a temperature drop occurs in the adsorbent and in the vicinity of the adsorbent. In other words, as the reaction progresses, the desorption of the substance onto the adsorbent tends to be inhibited by the temperature drop.
以上のように、吸着、脱着の両プロセスにおいて反応進
行上熱的に阻害を受けるにも拘らず、従来の吸着剤を用

を促進する平文てがあまり講じられてはいないと云う問
題点があった。As described above, although the reaction progress is thermally inhibited in both adsorption and desorption processes, conventional concentration processes using adsorbents can easily reduce thermal inhibition and promote concentration. There was a problem in that the plain text was not given much attention.
本発明は以上のような欠点に鑑みてなされたものであり
、簡便に、吸着・脱着に伴う熱的反応阻害を軽減し、物
質の濃縮促進を行なうことが可能な濃縮装置を提供する
ことを目的としている。The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a concentrating device that can easily reduce thermal reaction inhibition associated with adsorption/desorption and promote concentration of substances. The purpose is
上記目的を達成するために、本発明の吸着剤を用いた濃
縮装置は、物質の吸着プロセスを内部に持つ容器と脱着
プロセスを内部に持つ容器の一部又は全部が接触してな
る構成を有することを特徴とする。In order to achieve the above object, a concentrating device using the adsorbent of the present invention has a structure in which a container having a substance adsorption process therein and a container having a desorption process therein are partially or entirely in contact with each other. It is characterized by
上記のように構成された濃縮装置では、以下の様に機能
し、物質が濃縮促進される。The concentrator configured as described above functions as follows to promote concentration of substances.
物質の吸着剤への吸着プロセスにおいては、発熱反応が
起こり、吸着剤及び吸着剤近傍の温度が上昇する。一般
に、吸着剤への物質の吸着特性は低温である程、単位吸
着剤量当り吸着量が多く、この温度上昇は単位吸着剤量
当り吸着量を減少せしめてしまう。In the process of adsorption of a substance onto an adsorbent, an exothermic reaction occurs and the temperature of the adsorbent and the vicinity of the adsorbent increases. Generally, the adsorption characteristics of a substance to an adsorbent are such that the lower the temperature, the greater the amount of adsorption per unit amount of adsorbent, and this temperature increase will reduce the amount of adsorption per unit amount of adsorbent.
一方、物ｉの吸着剤への脱着プロセスにおいては、吸熱
反応が起こり、吸着剤及び吸着剤近傍の温度が降下する
。一般に、吸着剤への物質の脱着特性は高温である程、
脱着が容易であって、この温度降下は脱着を阻害してし
まうことになる。On the other hand, in the desorption process of substance i onto the adsorbent, an endothermic reaction occurs, and the temperature of the adsorbent and the vicinity of the adsorbent decreases. In general, the higher the temperature, the better the desorption characteristics of substances onto adsorbents.
Desorption is easy, and this temperature drop will inhibit desorption.
ところが、本発明では、吸着プロセスを内部ｔこ持つ容
器と脱着プロセスを内部に持つ容器の一部又は全部が接
触してなる構成をもつ為に、吸着プロセス側の容器から
脱着プロセス側の容器へ熱移動がなされることになる。However, in the present invention, since the container having the adsorption process internally and the container having the desorption process internally are partially or completely in contact with each other, there is no flow from the adsorption process side container to the desorption process side container. Heat transfer will take place.
従って、吸着プロセスの発熱骨の一部または全部は脱着

、ひいては物質の濃縮促進を行うことが可能になる。Therefore, part or all of the heat generated during the adsorption process moves to the container on the desorption process side, suppressing the temperature rise of the adsorbent and the vicinity of the adsorbent during the adsorption process, and increasing the adsorption amount of the substance per unit adsorbent. become. On the other hand, in the desorption process, heat transfer from the adsorption process promotes desorption. As described above, the adsorption/desorption reaction of the substance to the adsorbent is easily promoted, and thus it becomes possible to promote the concentration of the substance.

Moreover, one side of the three-way valve B5 is connected to the pipe through which the three-way valve A4 is connected to the pressurizer 2, and the remaining three sides are connected to the suction side of the suction pump 3 and the adsorption tower 9, respectively.

うに位置している。The suction pump 3 discharges the adsorption gas 12. Above the adsorption tower 9, piping is installed across the valve D7, and the non-adsorbed gas 1
1 can be discharged. As shown in FIG. 2, the structures of the adsorption towers 8 and 9 are cylindrical, and each contains adsorbents 14 and 15 that selectively adsorb specific gases. Further, the shape of the adsorption tower 8 has a cylindrical cavity inside, and the cylindrical adsorption tower 9 is located in such a way that its side surface is just in contact with the cavity.

吸着量の減少化を抑制することができることになる。Furthermore, the three-way valve B5 is open on the adsorption tower 9 and suction pump 3 sides, and is closed only on the pressurizer 2 side. Furthermore, as shown in FIG. 2, adsorbents 14 and 15 for selectively adsorbing special vehicle gas are packed in the adsorption tower 8.9 in the form of pellets. A portion of the supplied gas 1 is selectively adsorbed by the adsorbent 14 in the adsorption tower 8 . At this time, since the adsorption phenomenon is accompanied by heat generation, the temperature of the adsorbent 14 and the vicinity of the adsorbent 14 rises, and the saturated adsorption amount decreases as the temperature increases, so the adsorption amount per unit amount of adsorbent usually decreases. However, in the present invention, since the adsorption tower 8 in the adsorption process and the adsorption tower 9 in the desorption process come into contact and heat transfer is easily performed, part or all of the heat generated during adsorption is absorbed from the adsorption tower 8. It will be discharged to column 9. Therefore, adsorbent 14 and adsorbent 1
The temperature rise near 4 is suppressed, and the decrease in the amount of gas adsorbed per unit amount of adsorbent can be suppressed.
一方吸着塔９においては予め特定ガスを選択的に吸着し

。On the other hand, in the adsorption tower 9, a specific gas that has been selectively adsorbed in advance is desorbed by operating the suction pump 3, and is sent to a required location as an adsorbed gas 12 in a concentrated state. In this way, one cycle of the gas concentration operation is completed.

スにおける脱着が促進されることになる。At this time, an endothermic reaction occurs as the gas is desorbed. Although gas desorption is promoted at higher temperatures, the temperature of the adsorbent decreases due to the above-mentioned endothermic reaction, making desorption inhibition more likely to occur. However, in the present invention, since the adsorption tower 8 in the adsorption process and the adsorption tower 9 in the desorption process come into contact and heat transfer is easily performed, part or all of the heat generated during adsorption is absorbed from the adsorption tower 8. The heat will be transferred to tower 9. Therefore, desorption in the desorption process when heat is supplied is promoted.

。Next, the adsorption tower 8 that has completed the adsorption process enters the desorption process, and on the other hand, the adsorption tower 9 that has completed the desorption process enters the adsorption tower 9 (the operation at this time is the same as the operation method described above, and the explanation of the operation will be omitted. ) The concentration operation will be repeated continuously.

が可能な濃縮装置を提供することができる。Note that the non-adsorbed gas is discharged through valve C6. As described above, part or all of the heat generated in the adsorption process is transferred by bringing the containers containing both the adsorption process and the desorption process into contact with each other to transfer the heat. Part or all of the heat required for the desorption process can be supplied. Therefore, it is possible to alleviate or eliminate thermal reaction inhibiting factors that occur in each process, increasing the amount of material handled per unit adsorbent lid, and making it possible to perform simple and efficient concentration operations. A concentrating device can be provided.
なお、吸着プロセスと脱着プロセスは、上記実施例の如
