<p>PURPOSE:To retain the water content contained in an adsorbent always at an optimum state by counting the heating time of a heater corresponding to the steam feeding volume and feeding back the information to a temperature and relative humidity regulating device. CONSTITUTION:The air F containing CO2 first comes into a temperature relative humidity regulating device 11 and so regulated as to make the performance of an adsorbent as optimum. After that, the same is guided into an adsorption tank 12, and CO2 in the air F is adsorbed by the filling adsorbent 13 go turn into purified air and exhausted out of the tank 12. On the other hand, the adsorbent 13 out of which CO2 is adsorbed to the limit of adsorption capability is transferred to the regenerating process, and steam from a water vapor generator 14 generated by the heating of a heat 15 is fed to the adsorption tank 12 and CO2 gas is desorbed gradually starting from an inlet section. When a temperature switch 16 of the outlet of the adsorption tank 12 comes up to the given temperature, the regenerating process is finished, and the heating time during said process is measured by a counter 17 and the feeding volume of steam is calculated.</p> |
