example 1

[0025] Example 1. The diameter (inner diameter) of the prilling tower is Φ11 meters, the effective height is 40 meters (from the prilling head to the bottom of the tower), and the total height is 48 meters. A total of 16 exhaust fans with a diameter of 1 meter are used and are evenly installed in a circle at a distance L of 1 meter from the inner wall of the tower.

example 2

[0026] Example 2. The diameter (inner diameter) of the prilling tower is Φ12 meters, the effective height is 45 meters (from the prilling head to the bottom of the tower), and the total height is 54 meters. A total of 20 exhaust fans with a diameter of 1 meter are used and installed in a circle at a distance L of 1.2 meters from the inner wall of the tower. The actual operating capacity is 16 tons / hour, and more than 90% of the particle size is ≥ 2.5 mm.

Abstract

The invention provides the air-cooled crystallization prilling device for full-melting compound fertilizers, which comprises a prilling tower (1) and a rotary prilling head (2), wherein, the height of the prilling tower (1) is 15m to 70m, and the diameter thereof is 6m to 18m; the rotary prilling head (2) is mounted in the center of the top part on the inner side of the prilling tower (1); a cone-shaped collector (4) is connected to the lower part of the prilling tower (1); the invention is characterized in that a circle of exhaust fans (3) are at least mounted at the top of the prilling tower (1); the air inlets of the exhaust fans (3) are communicated with the inner cavity of the prilling tower (1); the distance L between the edge of the outermost exhaust fan (3) and the inner wall of the prilling tower (1) is 0.9m to 2.5m; a circle of air-inlet windows (5) with the height H thereof being 1.2m to 3m are formed at the bottom of the prilling tower (1) and the upper part of the cone-shaped collector (4); a conveying device (6) is mounted below the discharge hole of the cone-shaped collector (4); and a drum cooler (7) is mounted at the discharging end of the conveying device (6). The invention has the advantages of good prilling effect and convenient manufacture and installation.

Description

technical field [0001] The invention relates to a compound fertilizer granulation and forming device, in particular to an air-cooled crystallization granulation device for a full-melt compound fertilizer, in particular to a new tower-type air-cooled granulation device for a full-melt compound fertilizer. Background technique [0002] In recent years, the production process of producing full-melt compound fertilizer (ie NPK compound fertilizer) in my country has been greatly improved. The process has a series of problems such as low efficiency, poor appearance of the finished product, and high energy consumption. For this reason, people have invented a new tower granulation process. The products produced by this process have a round appearance, accurate and uniform nutrients, and high fertilizer utilization. Popular. However, the main problem of this process is that in order to increase the cooling effect, the tower body is mostly more than 100 meters, and the tower diameter i...
