It is granulated in chamber 101 and chemical reaction occurs with calcium carbide and influences the performance of calcium carbide.For example, segmentation wind and cooling wind can serve as reasons
The air-flow that argon gas is formed, wherein segmentation wind is the argon gas stream with segmentation effect, cooling wind is the low temperature with cooling effect
Argon gas stream, it is preferable that segmentation wind can be the argon gas stream of the low temperature with segmentation effect, so split wind and enter to calcium carbide fluid column
It is cooled while row segmentation, it is possible thereby to further improve the efficiency that carbide liquid is granulated.
The course of work of above-mentioned carbide liquid prilling granulator 100 is described below with reference to Fig. 1：
High temperature carbide liquid is dropped down onto on comminutor 2 under being granulated by import entrance in chamber 101 afterwards, and comminutor 2 turns carbide liquid
Become to make after calcium carbide fluid column it to be sliding downwardly and off comminutor 2, the first blowing device is by the first air inlet 112 towards being granulated chamber
Segmentation wind is passed through in 101, calcium carbide fluid column is divided into multiple calcium carbide drops by segmentation wind, and the carbide liquid being separated to form drops in granulation chamber
Free-falling from top to bottom in room 101, in the cooling air cooling that dropping process is entered by the second air inlet 122, i.e. carbide liquid
Drop and cooling wind are exchanged heat, and due to surface tension effects, carbide liquid is punctured into spherical during dropping in gradually cooling and solidifying
Chamber 101 is granulated by the discharge of outlet 102 after grain.
According to the carbide liquid prilling granulator 100 of the utility model embodiment, carbide liquid is transformed into calcium carbide fluid column first, connect
And calcium carbide fluid column is divided into multiple calcium carbide drops, and calcium carbide drop is cooled down to form calcium carbide particle.By calcium carbide fluid column
It is transformed into multiple calcium carbide drops, i.e., the breakage of calcium carbide is realized in liquid, it is possible thereby to avoids calcium carbide shattering process from producing powder
And environment is polluted, and calcium carbide drop is cooled down, calcium carbide drop greatly increases with cooling down the heat exchange area of wind, changes
Heat is more abundant, and the cooling effectiveness of calcium carbide greatly improves, and thus substantially increases the efficiency of calcium carbide granulation.In addition, calcium carbide is broken
Broken and cooling procedure is carried out in granulation tower 1, thus not only increases the effective rate of utilization of factory area, and can be with
Avoid transporting calcium carbide back and forth using overhead traveling crane, simplify production technology, improve production efficiency.
In one embodiment of the present utility model, as shown in Fig. 1-Fig. 4, comminutor 2 includes central axis along vertically
The body 21 of the umbrella of direction extension, from top to bottom gradually the top of increase and body 21 has a circle to the cross-sectional area of body 21
Shape platform and the underface for being located at import, the side wall of body 21 are provided with the groove 211 of a plurality of circumferentially spaced setting, every groove
211 both ends extend respectively to the circular platform at the top of body 21 and the lower edge of body 21, specifically, the upper end of groove 211
