Description

Technical Field

[0001] This utility model relates to the technical field of spraying devices, and in particular to a spraying device for the top of a granulation tower. Background Technology

[0002] In fertilizer production, top spraying devices for granulation towers are widely used in the granulation process. By uniformly spraying liquid containing fertilizer components into the granulation tower, a uniform liquid film is formed on the surface of the rapidly falling fertilizer granules. The residual heat of the granules evaporates the moisture, forming a coating, which also helps cool the granules and reduces energy consumption for ventilation and cooling. The use of spraying devices can significantly improve the particle size and density of fertilizers, thus improving fertilizer quality.

[0003] For example, in a class of prior art represented by application number CN201420507248.2, the main structure includes a polyglutamic acid solution storage tank and a high tower.
