る。As shown in FIG. 3, a lower opening 22 and an upper opening 2 are provided.
Below the inside of the adsorption tower 21 provided with
A floor plate 24 formed with a plurality of a is provided, and the adsorption tower 21
Above the inside of the table, a top plate 2 having a plurality of through holes 25a is formed.

The inside of the adsorption tower 21 surrounded by the metal nets 26 and 27 is filled with a granular adsorbent 28 that adsorbs a predetermined gas.

上部口２３から吸着塔２１の外側へ送り出される。In such an adsorption device, when the raw material gas is fed from the lower port 22 into the adsorption tower 21, the raw material gas passes through the through holes 24a of the floor plate 24 and the metal net 26 and flows into the layer of the adsorbent 28, Only a predetermined gas component in the raw material gas is adsorbed by the adsorbent 28. The gas that is not adsorbed passes through the wire net 27 and the through hole 25 a of the top plate 25 and is sent out of the adsorption tower 21 through the upper port 23.

The predetermined gas component adsorbed by the agent 28 is released from the adsorbent 28, and the lower port 22
Is sent to the outside of the adsorption tower 21 and collected. By repeating the above operation, it is possible to continuously purify the raw material gas into only predetermined gas components.

てしまう。In the adsorption device as described above, the difference in flow pressure between the lower port 22 side and the upper port 23 side of the upward flow generated in the adsorption tower 21 due to the supply of the raw material gas,
That is, rather than the pressure loss of the upward flow, the difference in the flow pressure between the upper port 23 side and the lower port 22 side of the downward flow generated in the adsorption tower 21 with the supply of the purge gas, that is, the pressure loss of the downward flow. On the other hand, as shown in FIG. 4, the flow velocity increases remarkably as the flow velocity becomes higher.
【０００７】なぜなら、上昇流は、吸着剤２８の層内の

過の際に吸着剤２８を圧縮するように押しつけるため、
吸着剤２８の層は、空隙率が小さくなり、下降流が通過
しにくくなるからである。Because the upward flow pushes up the adsorbent 28 so that the adsorbent 28 diffuses when passing through the layer of the adsorbent 28, the layer of the adsorbent 28 has a large porosity, and the upward flow easily passes through. However, since the downward flow pushes the adsorbent 28 to compress it as it passes through the bed,
This is because the layer of the adsorbent 28 has a small porosity, which makes it difficult for the downward flow to pass through.
【０００８】このため、上昇流及び下降流の速度を速く

損失が著しく増大してしまい、逆に効率が悪くなってし
まう。Therefore, even if an attempt is made to shorten the processing time by increasing the speed of the ascending flow and the descending flow, the pressure loss is remarkably increased in the descending flow, and conversely the efficiency is deteriorated.
