【発明の詳細な説明】 〔産業上の利用分野〕 本発明はプレートフィン熱交換器一体型吸着装置に関
し、さらに詳しくは吸着物質を吸着した吸着剤の再生を
効率よく行うことがきるプレートフィン熱交換器一体型
吸着装置に関する。The present invention relates to a plate fin heat exchanger-integrated adsorption device, and more particularly to a plate fin heat that can efficiently regenerate an adsorbent that has adsorbed an adsorbed substance. The present invention relates to an exchange-type adsorption device.
従来、吸着分離装置における吸着剤の再生方法には、温

ing Adsorption)と、圧力を低くして吸着物質を脱着す
る方法(PSA:Pressure Swing Adsorption)とがある。Conventionally, as a method of regenerating an adsorbent in an adsorption separation device, a method of desorbing an adsorbed substance by increasing the temperature (TSA: Thermal Swing) is used.
ing Adsorption) and a method of lowering the pressure to desorb the adsorbed material (PSA: Pressure Swing Adsorption).

流に行われている。しかし、これらのTSAによる方法で

欠点がある。すなわち、前者の直接加熱では、吸着剤の
加熱、冷却に多量のスチームおよびパージガスが必要で
あり、冷却に長時間を必要とする。また後者の間接加熱
でも、吸着層内に伝熱管を埋め込むか、シェルアンドチ
ューブ熱交換器のチューブ内に吸着剤を詰めて行うため
伝熱面積を充分大きくとれず、吸着剤の加熱、冷却に長
時間を必要とする。In the TSA, there are a method of directly heating and desorbing an adsorbent with high-temperature gas or steam, and a method of indirectly heating and desorbing with a heat exchanger type adsorption tower, and the former is mainly used. ing. However, these TSA methods have a drawback that the adsorption / desorption cycle takes a long time of several hours to several days. That is, in the former direct heating, a large amount of steam and purge gas are required for heating and cooling the adsorbent, and a long time is required for cooling. Even in the latter indirect heating, the heat transfer area cannot be sufficiently large because the heat transfer tube is embedded in the adsorption layer or the adsorbent is packed in the tube of the shell-and-tube heat exchanger. It takes a long time.
一方、PSAは系の圧力変化によって吸・脱着を行う方法
であるが、この際にも吸着熱による発熱、吸熱が起こ
り、吸着塔内の温度が変化して吸着剤の利用効率が低下

伝熱管を設置することが考えられるが、伝熱面積が充分
にとれず、また吸着剤粒子間の伝熱が悪く、不均一な温
度分布になるなどの理由で工業的規模の装置にはほとん
ど使用されていない。On the other hand, PSA is a method of absorbing and desorbing by changing the pressure of the system, but also at this time heat generation and heat absorption due to adsorption heat occur, the temperature in the adsorption tower changes and the utilization efficiency of the adsorbent decreases There is. It may be possible to install a heat transfer tube in the adsorption tower to solve this problem, but the heat transfer area cannot be sufficient and the heat transfer between the adsorbent particles is poor, resulting in an uneven temperature distribution. For this reason, it is rarely used in industrial scale equipment.
従来のPSAには熱交換器が使用されることがあるが、こ

・脱着のサイクルと一致せず行うことができかった。A conventional PSA may use a heat exchanger, but this is done to keep the temperature inside the adsorption tower constant, and it is done for the purpose of combining PSA and TSA. Not a thing. These combinations could not be performed because the heating and cooling of conventional heat exchangers took too long, which did not coincide with the PSA adsorption / desorption cycle.

剤3とから主として構成される。This apparatus includes a plurality of partition plates 1, heat medium channels 4A formed by the partition plates 1 in alternate steps, and heat transfer fins 2A provided in the heat medium channels 4A in the flow direction and direction. A processing gas channel 4B formed between the heat medium channels 4A and having a flow direction different from the heat medium channel 4A by 90 °.
The process gas flow path 4B is mainly composed of heat transfer fins 2B provided in the same direction as the flow direction, and an adsorbent 3 filled in the process gas flow path 4B.

どが用いられるが、これらに限定されるものではない。As the heat transfer fins 2A and 2B provided in each flow path, for example, the fins arranged in high density shown in FIGS. 3 and 4 are used. FIG. 3 shows wavy and long fins, and FIG. 4 shows wavy and short fins arranged in a staggered manner in the flow direction. The width between the fins is preferably about 3 to 8 mm. Zeolite, activated carbon and the like are used as the adsorbent 3 to be filled, but the adsorbent 3 is not limited to these.

によってさらに急速加熱、急速冷却が可能となる。In the heating and cooling, since the heat transfer area is increased by the heat transfer fins 2A and 2B provided in the flow paths 4A and 4B, a uniform temperature distribution can be obtained in a short time. Therefore, the adsorption / desorption cycle time can be significantly shortened.
