摘要
Provided is a compact activated carbon regenerative furnace (regenerating method) to facilitate incorporation into gas purification apparatuses; further provided are a gas purification method and apparatus that use the activated carbon regenerative furnace and enable the rate of removal of chemical substances in exhaust gas to be kept at a high level over a long period. The activated carbon regenerative furnace is provided with an activated carbon supply section (21) for supplying activated carbon (K) having lowered adsorption capacity, an activated carbon regenerating section (22) wherein is formed a moving bed through which the supplied activated carbon flows downward due to gravity, and the activated carbon (K) is regenerated by the activated carbon (K) and water vapor (V) being brought into countercurrent contact in the presence of heat in the moving bed and a water gasification reaction being induced, a cooling section (26) for cooling the regenerated activated carbon, and an activated carbon discharge section (27) for discharging the cooled activated carbon. The weight ratio (WV/WK) of the flow rate (WV)(kg/h) of the water vapor and the flow rate (WK)(kg/h) of the activated carbon that are brought into countercurrent contact is preferably set to 0.05-1.0.
