The utility model relates to a vertical continuous prilling granulator in petrochemical technology field, it mainly comprises casing, cyclone, reinforced import, foraminiferous swash plate, fluidization air intlet A, air sifter air intlet, big grain exports, air -blower, fluidization air intlet B, pump, binder import and binder shower nozzle. Have pump, binder import, air -blower, fluidization air intlet B at the casing left part, at inside binder shower nozzle, foraminiferous swash plate and the big grain exports of being equipped with of casing, the right part is equipped with cyclone, reinforced import, fluidization air intlet A, air sifter air intlet, the partly fluidization air intlet B entering casing of following of fluidization air that the air -blower drum is gone into, another subtotal binder mixes the back and imports the entering casing from the binder. It has the aperture to open in the foraminiferous swash plate, and the diameter is less than produces the particle diameter, fluidization air intlet A and fluidization air intlet B adopt the design of symmetrical formula, reinforced import and binder import are on same straight line.
