The invention relates to a movable radioactive gas treatment system under accident conditions. The system comprises a primary filtering mechanism and a secondary filtering mechanism which are interconnected, the primary filtering mechanism comprises a gas inlet pipeline, and the gas inlet pipeline is connected with an aerosol pre-filter, a sol high-efficiency filter and an iodine removal unit; andthe secondary filtering mechanism comprises a drying bed connected with the iodine removal unit through the gas inlet pipeline, the gas outlet end of the drying bed is connected to one or more delaybeds through one or more gas inlet branch tubes, every delay bed is provided with a gas inlet end and a gas outlet end, the gas inlet end of every delay bed is connected with a regeneration circuit branch tube, and all the regeneration loop branch tubes are connected with a regeneration loop main tube. The designed purification system continuously purifies and exchanges air in the living environment of the personnel under the accident condition through the activated bed purging regeneration of the delay beds, so the system can realize the staged purification treatment of radioactive aerosol, radioactive iodine and inert gas in the gas.
Description
technical field [0001] The invention belongs to the technical field of the nuclear industry, in particular to a mobile radioactive gas processing system used under accident conditions. Background technique [0002] In the event of a nuclear facility accident, there may be a risk that a large amount of radioactive iodine, aerosol, and inert gas will be released into the habitable environment such as the main control room and emergency building. In order to ensure the safety of the environment where the personnel live and the emergency treatment of the personnel as long as possible under the accident conditions, it is necessary to purify the living environment of the personnel. For radioactive aerosols, high-efficiency filters can be used for filtration and purification, while radioactive iodine is adsorbed by traditional iodine adsorbers equipped with activated carbon. For fission products such as radioactive inert gases Xe and Kr, the current treatment mainly adopts two met...
