TEDA and methyl iodide desorption method and its apparatus in impregnated TEDA activated carbon using fluidized bed

摘要

The present invention relates to a method and apparatus for desorbing TEDA using hot air in a fluid bed desorption process for recycling TEDA impregnated activated carbon used for removing radioactive iodine, When the heated air is introduced while the fluidized bed desorption method is maintained at the high temperature, the hot air and the used impregnated activated carbon come into contact with each other in the fluidized state, and desorbed from the activated carbon due to the volatility of TEDA and organic iodine, A method and apparatus for desorbing TEDA and organic iodine from impregnated activated carbon used since it is discharged by the method.
