A system and method for cyclone-type self-absorption storage of dehydrated phosphogypsum. The system comprises a foundation base (1). A first telescopic rod member (4) is fixedly mounted at the top of the foundation base (1); a first box body (5) is fixedly mounted at the top of the first telescopic rod member (4); a fixing block (6) is fixedly mounted at the top of the first box body (5); a first rotating shaft (7) is movably mounted in the fixing block (6); a second telescopic rod member (8) is fixedly mounted on one side of the first rotating shaft (7); a second box body (10) is fixedly mounted at an end portion of the second telescopic rod member (8); and one side of the second box body (10) communicates with a feeding pipe (15). By providing the related second box body (10), a drying box (13), a first driving electric motor (12) and a mixing device (16), when a related production operation is performed on the whole system, a related stirring and mixing device and the drying device can be used, such that when the related production operation is performed, the whole dehydration process can be more stable, which can effectively avoid problems where the phosphogypsum is prone to agglomerating, it is difficult to dehydrate the interior after agglomeration, and the dehydration effect is affected.
