<p>PURPOSE:To continuously separate and remove CO2 in a waste gas while taking a smoke source with a large capacity as an object by making it possible to continuously rotate and move a container in which a CO2 gas adsorbent is stored to put the container in a low temperature CO2-containing gas region and a high temperature reproduced gas region reciprocally. CONSTITUTION:A continuously adsorbing and reproducing apparatus 3 is formed as a cylindrical container in which basket-like containers filled with a CO2 gas adsorbent (e.g. Ca-X-type zeolite) separately are put and so assembled as to become a horizontal rotary apparatus which can be moderately rotated subsequentially to a driving apparatus. For example, the apparatus 3 is connected with a gas duct of a gas (a) (15 volume of CO2 concentration at an inlet) containing CO2 gas in low temperature region (T1:40 deg.C) and with a gas duct of a high temperature (T2:150 deg.C) reproducing gas (c) to separate the adsorbed CO2 and continuously rotated to pass both gases to the adsorbent. Consequently, while passing the low temperature gas region, the adsorbent adsorbs CO2 gas at that temperature and while passing the high temperature reproducing gas region, it releases a gas (d) as a gas having 85volume% of CO2 from it.</p> |
