Device and method for continuously dissolving triuranium octaoxide

The invention discloses a method for continuously dissolving triuranium octaoxide. The method comprises the following steps: S1, pretreating a triuranium octaoxide material; drying the industrial triuranium octaoxide material until the water content of the industrial triuranium octaoxide material is less than or equal to 0.5%; the dried triuranium octaoxide is sieved, and impurities are removed; s2, preparing a triuranium octoxide dissolving acid solution; dissolving the triuranium octaoxide with acid liquor; s3, continuously dissolving the triuranium octoxide; and S4, flocculating and settling the dissolved slurry. 一种八氧化三铀连续溶解的方法，包括以下步骤：S1：八氧化三铀物料预处理；将工业八氧化三铀物料进行烘干，使其含水率≤0.5％；烘干后的八氧化三铀过筛，去除杂物；S2：八氧化三铀溶解酸液的配制；八氧化三铀采用酸液溶解；S3：八氧化三铀连续溶解；S4：溶解料浆絮凝沉降。
