Description

technical field [0001] The invention relates to a tower type urea granulation equipment, in particular to a tower type urea granulation rotary nozzle. Background technique [0002] The tower granulation of urea is generally to send the molten urine to the top of the granulation tower from the melting pump, and then input it into the granulation nozzle that is driven by the transmission device to rotate concentrically. The urine rotates with the nozzle and passes through the nozzle. The spray hole on the inner wall is sprayed and sprayed in the prilling tower. The cold air flow entering through the bottom of the tower contacts the surface of the sprayed liquid column in reverse. Due to the relationship between the surface tension of the liquid, the jet breaks and obtains droplets of similar size. The prilling tower falls in the air, and the molten material gradually solidifies during the gravity descent process, and after cooling, it changes from the initial liquid state to t...
