摘要
本含碘废气治理设施采用串联的波纹网式活性炭吸附器作为除碘单元。整个废气净化系统包括高效空气粒子过滤器、空气加热器、活性炭预吸附器、浸渍炭吸附器、中效空气粒子过滤器和排风烟囱等主要设备。对近６年来该设施的运行参数和环境监测结果进行综合分析表明：含碘废气治理设施性能可靠、运行稳定，放射性碘的总去除效率高于９９．３％，净化后排入大气的放射性碘量远低于排放限值（１．８５×１０８Ｂｑ／ｄ）。
o remove iodine, the ripplenet activated charcoal adsorbers are adopted and connected in series. The whole iodine removal system includes: HEPA filter, air heater, activated charcoal preadsorber, impregnated charcoal adsorber, MEPA filter and discharge chimney. The monitoring results indicate that the system is reliable and stable. The total iodine removal efficiency is over 99.3 %. The amount of iodine released into the atmosphere is much lower than the allowable limit of 1.85×108 Bq/d.
