摘要： [OBJECT] To provide a device for removing radioactive cesium from waste material containing radioactive cesium, doing so at low energy and in a dependable manner.
[MEANS OF REALIZING THE OBJECT] The removal device 1 for radioactive cesium is provided with: a rotary kiln 41 which is provided with a burner 41b supplying from the kiln outlet an organic matter 03 contaminated with radioactive cesium, and an inorganic matter charging port 41a supplying from the kiln inlet inorganic matter S4 contaminated with radioactive cesium, and which is employed to burn the organic matter 03 together with the inorganic matter S4; and a recovery device cooling tower 51, a cyclone 52, a bag filter 53 for recovering cesium that has volatilized in the rotary kiln. A drying/crushing device (dryer 21, crusher 22) for drying and crushing the organic matter O1 prior to charging the radioactive cesium-contaminated organic matter to the rotary kiln can be provided. Additionally, a reforming/drying/crushing device (reformer 31, dryer 32, crusher 23) for reforming, drying, and crushing the inorganic matter S1 can be provided. During burning of the organic matter 03 together with the inorganic matter S4, a calcium source can be added as a reaction accelerant A to the rotary kiln.摘要翻译： [目的]提供一种用于从含有放射性铯的废料中除去放射性铯的装置，以低能量和可靠的方式进行。 [实现对象的手段]放射性铯去除装置1设置有回转窑41，该回转窑41具有从窑出口供给被放射性铯污染的有机物质03的燃烧器41b和无机物填充口41a 从窑入口的无机物质S4供给，被放射性铯污染，用于与无机物质S4一起燃烧有机物质03; 回收装置冷却塔51，旋风分离器52，回收窑内挥发的铯的袋式过滤器53。 可以提供用于在将放射性铯污染的有机物质装入旋转窑之前将有机物质O1干燥并粉碎的干燥/破碎装置（干燥机21，破碎机22）。 此外，可以提供用于重整，干燥和粉碎无机物质S1的重整/干燥/破碎装置（重整器31，干燥器32，破碎机23）。 在与无机物质S4一起燃烧有机物质03时，可以将钙源作为反应促进剂A添加到回转窑中。
