<p>PURPOSE:To hold adsorbing capacity to a stable high stage, by providing a temp. regulation apparatus for regulating the temp. of CO2-containing gas to predetermined temp. to the gas introducing pipe side of an adsorbing tank. CONSTITUTION:Air is passed through an adsorbing tank 1 to adsorb CO2 and steam is introduced into an adsorbing tank 2 to desorb CO2. In this case, air is cooled by a cooler 3 prior to entering the adsorbing tank to remove moisture and passes through a heater 5 to adjust the temp. of air.Then, the rising in the temp. of steam is detected by a CO2 temp. detection sensor and a signal is outputted from a controller on the basis of the detection signal of said sensor and an automatic change-over valve is controlled to change-over the adsorbing tank 1 and the adsorbing tank 2. When CO2 is detected by a CO2 concn. detection sensor, the automatic change-over value is controlled in the same way and CO2 is recovered in a CO2 recovery tank 6.</p> |
