<P>PROBLEM TO BE SOLVED: To provide a method for regenerating activated carbon, by which the activated carbon on that a harmful gas is adsorbed fully and through that the harmful gas breaks can be regenerated efficiently in safe without wasting the activated carbon and to provide an air purifying system in which the activated carbon is incorporated and regenerated. <P>SOLUTION: This method for regenerating the activated carbon comprises the first step to regenerate the activated carbon by jetting superheated steam of 150-250°C toward the activated carbon when a low-boiling point substance is desorbed and the second step to regenerate the activated carbon by jetting superheated steam of 300-350°C toward the activated carbon when a high-boiling point substance is desorbed. This apparatus for regenerating the activated carbon is provided with a superheated steam supplying part, an adsorbent-packed part and an exhaust gas treating part. The superheated steam supplied from the superheated steam supplying part is jetted toward an activated carbon filter in the adsorbent-packed part. A temperature sensor is arranged on the downstream side of the adsorbent-packed part. A unit for decomposing the gas desorbed and separated from the activated carbon is arranged in the exhaust gas treating part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
