The utility model belongs to the technical field of atomizing and drying of materials and in particular relates to a drying tower atomization cyclone. The drying tower atomization cyclone comprises a cylindrical barrel body, wherein the top of the barrel body is provided with a sealed top cover; the bottom of the barrel body is provided with a discharge opening; and four streamline type tangential feeding holes are formed in an outer wall of the barrel body. By the setting of the positions of the feeding holes and the streamline type appearance, the slurry pressure inside the cyclone is obviously improved, and after the slurry is atomized and dried by utilizing the drying tower atomization cyclone, the product is good in pulverization effect and small in moisture content; and meanwhile, the problems that the tower body is easy to scale and a fluidized bed is easy to coke due to poor drying tower atomization effect are solved, the cleaning frequency of the tower body is reduced, the coking risk of the drying tower fluidized bed is reduced, the service life of equipment is prolonged, and the productivity is improved to a certain degree.
