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 pump the molten urine to the top of the granulation tower, and input it into the granulation nozzle that is driven by the transmission device to make a concentric rotation motion. The urine rotates with the nozzle and passes through the nozzle. The nozzle holes on the inner wall are sprayed out and sprayed in the prilling tower. The cold air flow entering through the bottom of the tower is in contact with the surface of the ejected liquid column in the reverse direction. The granulation tower falls in the air, and the molten material gradually solidifies and cools in the process of gravity falling, and changes from the initial liquid state to the solid state of spherical particles close to normal temperature. There are many types of traditional nozzle...
