問題を生じていた。[Problems to be Solved by the Invention] By the way, the desorption gas on the population side of the regeneration area 12.13 is heated by the heater 6a or 6b, so as to enhance the desorption effect of the predetermined component adsorbed on the adsorption member 3. ing. Therefore, the regeneration area 12 that comes into contact with the desorption gas
．． The temperature of the 13 adsorption members 3 increases, and the adsorption members 3 reach the adsorption area 11 six times in a high temperature state. Adsorption member 3
When the temperature reaches such a high temperature, the amount of adsorption of the adsorbent decreases, and the target component cannot be adsorbed as designed. As a result, the amount of the adsorbed target component that is not adsorbed and is discharged outside the system together with the adsorbed exhaust gas increases, or the amount of adsorption decreases, resulting in a lower concentration of the specified component in the desorbed exhaust gas in the regeneration area, resulting in an efficient gas flow. This caused the problem that adsorption/desorption processing could not be performed.

縮器８を効率的に運転できる。That is, by providing the cooling area 20, the adsorption area 11 has a temperature close to room temperature, and by circulating the exhaust gas that has passed through this area to the cooling area 20, it is heated to the regeneration area 12.
The adsorption member 3 heated in step 13 can be cooled to a temperature close to room temperature. Furthermore, since the cooled exhaust gas heated in the cooling region 20 is introduced into the entrance side of the regeneration region 12 as a desorption gas via the heater 6a, the heating energy for the desorption gas in the heater 6a can be reduced. The exhaust gas that has passed through the regeneration region 12 (arrow E, shown in the direction of force) is pressurized by the fan 5b, and a part of it flows through the re-adsorption region 14 (shown in the direction of arrow A) through the cooler 9. The exhaust gas is supplied by the raw material gas supply fan 5a.
circulate to the inlet side. On the other hand, a part of the gas branched at the outlet side of the fan 5b is sent to the heater 6b together with the gas pressurized by the fan 5C, and after flowing through the regeneration area 13 in the direction of arrow E2, part of it is used as the final It is led out of the system as desorbed exhaust gas. This play area 13
Since the gas flowing through the circuit circulates through a circulation system provided with a heater 6b and a fan 5C, the predetermined components desorbed in the circulation system are increased to a certain concentration, and a part of this circulating gas is quantified. Since the water is taken out and introduced into the condenser 8, the condenser 8 can be operated efficiently.

とができる。When observing the gas passing through the cooling region 20 from the viewpoint of adsorbed component concentration, the gas on the inlet side of the cooling region 20 is
Since it is a part of the exhaust gas in 1, it is presumed that it contains a small amount of the predetermined component that could not be adsorbed. , the unadsorbed adsorbed components can be almost completely adsorbed here. Furthermore, when this cooled exhaust gas is used as a desorption gas in the regeneration region 12, since the concentration of adsorbed components in the gas is extremely low, excellent desorption performance can be exhibited for the adsorption member.

単な構造で済む様になる。In addition, in terms of mechanical structure, a part of the exhaust gas after passing through the adsorption area 11 is used as the gas to be passed through the cooling area 2o, so that the header member 4b as shown in FIG. The header can be formed as a single header that communicates the population side of the adsorption area 11 with the outlet side of the adsorption area 11, and there is no need to separate the inlet side and the outlet side, resulting in a simple structure.

The difference from the embodiment shown in the figure is that part of the raw material gas before being introduced into the adsorption area 11 is used as the cooling gas passed through the cooling area 20. In addition to cooling the member 3, adsorption of the component to be adsorbed can be performed in the cooling region 20, and the amount of raw material gas supplied to the adsorption region 11 can be reduced.

40 is introduced into the inlet side and the adsorption member is made to flow in the direction of arrow A2, thereby increasing the absorption amount of the target component to be adsorbed. Further, in order to make the exhaust gas that has passed through the regeneration area 13 (indicated by arrow E2) highly concentrated before being introduced into the condenser 8, a bypass passage 10 and a ° fan 5C are provided to transfer the exhaust gas on the outlet side of the condenser 8 to the regeneration area 13.
