Description

Technical Field

[0001] The utility model relates to a carbon canister used for an activated carbon dynamic adsorption experiment, belonging to the technical field of activated carbon adsorption experiments. Background Art

[0002] During the operation of the reactor, a variety of fission gas products are released from the core, including radioactive inert process gases krypton and xenon. In the early days, the compressed tank storage decay method was mostly used to reduce its radioactivity to a dischargeable level. However, this method pressurizes the upstream exhaust gas for storage, and the radioactivity concentration of the concentrated gas is greatly increased. High-pressure storage increases the risk of radioactive leakage and increases the difficulty and cost of personnel radiation protection and shielding. Secondly, due to the high concentration of hydrogen in the exhaust gas to be decayed, long-term high-pressure storage poses safety risks such as hydrogen explosion and leakage, and increases the difficulty and cost of fire prevention, explosion prevention, ventilation, and fire protection. The process requires the corresponding pressurization devices, such as compressors and buffer tanks, which not only increase costs and energy consumption, but also make the operation and control of the system more complicated. In addition, the decay box is large in size and requires more plant space.

[0003] In recent years, this method has been gradually replaced by the safer, more economical and feasible activated carbon retention bed adsorption decay method. As the filling material of the retention bed of the radioactive waste gas treatment system, the performance of activated carbon is directly related to the retention performance of the retention bed.

[0004] Since multiple experiments need to be conducted during the activated carbon adsorption coefficient experiment to ensure the accuracy of the results, the delayed bed used in the prior art is not convenient for replacing the activated carbon, which affects the experimental efficiency.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
