It is configured to increase. Therefore, the temperature of the adsorbing members 3 of the first and second regenerating regions 13 and 12 that come into contact with the desorption gas increases, and the adsorbing members 3 move to the adsorbing region 11 in a high temperature state. When the adsorbing member 3 is brought into such a high temperature state, the adsorbing amount of the adsorbent decreases, and the adsorbing target component cannot be adsorbed as designed. As a result, the amount of the target component to be adsorbed and discharged to the outside of the system together with the adsorbed exhaust gas increases, or the amount of the adsorbed gas decreases. There has been a problem that the absorption / desorption process cannot be performed.

The heated adsorption member 3 in 3 and 12 can be cooled to a temperature near normal temperature. Further, since the cooling exhaust gas heated in the cooling area 20 is introduced as a desorption gas to the inlet side of the second regeneration area 12 via the heater 6a,
The heating energy of the desorption gas in 6a is small. Note the second regeneration region 12 (indicated by arrows E 1 direction) passing the exhaust gas partially pressurized by the fan 5b is allowed to flow re-adsorption region 14 through the cooler 9 (indicated by an arrow A 2 direction), Further, the exhaust gas is joined to the inlet side of the raw material gas supply fan 5a.

ができる。When observing the gas passing through the cooling region 20 from the aspect of the concentration of the adsorbed component, the gas on the inlet side of the cooling region 20 is a part of the exhaust gas in the adsorption region 11, and thus contains a small amount of a predetermined component that could not be adsorbed. It is presumed that the cooling area 20
In the above, the adsorbing member immediately after passing through the second regeneration area 12 is cooled and circulated, whereby the unadsorbed adsorbed component can be almost completely adsorbed here. Further, when the cooled exhaust gas is used as a desorption gas for the second regeneration region 12, the adsorption component in the gas has an extremely low concentration, so that excellent desorption performance can be exhibited for the adsorption member.

However, in the above embodiment of the present invention, a part of the exhaust gas is removed. As a result, the amount of unadsorbed components discharged from the exhaust port 11a as they are can be reduced.

また冷却領域を通過した排ガスは再生領域で再利用で
きるので、熱利用の面及び所定成分回収の面で効率的な
ガス吸・脱着処理が行なえる様になった。In addition, since the exhaust gas that has passed through the cooling area can be reused in the regeneration area, efficient gas absorption and desorption can be performed in terms of heat utilization and recovery of predetermined components.
更に循環ラインで脱着された所定成分は一定濃度まで
高められ、この再生ガス（循環ガス）の一部を定量的に
取出して凝縮回収部（凝縮器）へ導入できるので、凝縮
回収部を効率的に運転できる様になった。Further, the predetermined component desorbed in the circulation line is increased to a certain concentration, and a part of the regenerated gas (circulating gas) can be quantitatively extracted and introduced into the condensation and recovery unit (condenser), so that the condensation and recovery unit is efficiently operated. I can now drive.
