Description

technical field [0001] The invention belongs to the technical field of mechanical design, and in particular relates to an online activation device for an activated carbon adsorption system of a nuclear power plant, and is especially suitable for the activation and regeneration of radioactive activated carbon in a nuclear power plant's detaining bed. Background technique [0002] The function of the nuclear power plant radioactive gas treatment system is to remove the radioactive inert gas krypton and xenon in the waste gas of the nuclear power plant, and its core component is the activated carbon in the stagnant bed. Since the commissioning, during the operation of the system, the humidity in front of the stagnant bed is relatively high (maximum 7.63g / m for the main series 3 , the relative humidity is about 36%, and the maximum auxiliary series is 16.08g / m 3 , about 76% relative humidity), always higher than the design value of 0.5g / m 3 . [0003] According to research, t...
