挥发性铯化合物的过滤型捕集剂及挥发性铯化合物的捕集方法

Filter type trapping agent for volatile cesium compound and trapping method for volatile cesium compound thereof
Abstract:
A filter type trapping agent for volatile cesium compound and trapping method for volatile cesium compound thereof are provided. More particularly, a filter type trapping agent for volatile cesium compound including silica 40-65% by weight of silica, 15-30% by weight of alumina, 5-15% by weight of iron oxide, 1-15% by weight of molybdenum oxide, 1-10% by weight of chromium oxide, and 1-10% by weight of vanadium oxide and trapping method for volatile cesium compound thereof are provided. Through a filter type trapping agent for volatile cesium compound and a trapping method, only cesium can be selectively separated among the nuclear fission gases. Accordingly, by disposing only the filter where cesium is trapped, the efficiency of an off-gas process improves, expense for disposing filter wastes decreases, and a cesium isotope of the waste filter can be recycled. Therefore, many forms of cesium compound gas are made insoluble efficiently.
Abstract(Chinese):

提供了挥发性铯化合物的过滤型捕集剂和挥发性铯化合物的捕获方法。 更具体地，涉及一种用于挥发性铯化合物的过滤型捕集剂，包括二氧化硅40-65％（重量），氧化铝15-30％（重量），氧化铁5-15％，氧化铁1-15％ 氧化物，1-10重量％的氧化铬和1-10重量％的氧化钒，并且提供其挥发性铯化合物的捕获方法。 通过用于挥发性铯化合物的过滤型捕集剂和捕集方法，只能在核裂变气体中选择性分离铯。 因此，通过仅设置铯被捕获的过滤器，废气处理的效率提高，处理过滤废物的费用降低，废弃过滤器的铯同位素可以再循环。 因此，许多形式的铯化合物气体被高效地溶解。
