A separation device, comprising: a third-stage cyclone housing, a separating unit, and a granule recycle and regeneration unit, wherein, the separating unit is disposed inside the third-stage cyclone housing and comprises: a cyclone separator and a moving bed coupled to each other; the granule recycle and regeneration unit comprises: a riser, a spouted bed regenerator, and a regeneration pipe connecting the spouted bed regenerator with the moving bed; the spouted bed regenerator has upper and lower ends opposing to each other, wherein, the upper end of the spouted bed regenerator is provided with a sleeve which opens downwardly, the sleeve divides an interior of the spouted bed regenerator into a fountain area and an annular gap area, and a regenerating gas outlet which is in communication with the annular gap area is provided on a side wall of the spouted bed regenerator. A centrifugal separation and intercepting filtration of the moving granular bed to fine particles can separate fine particles under low pressure drop, and can continuously separate the captured dust particles and the moving bed granules ensuring a sustainable recycling of the moving bed granules.
