Abstract
High-tower melting granulation technique under a kind of high humidity high-heat environment, is as follows：A, the phosphorus ammonium of 25 15 5 raw material total amount 23 33% of composite fertilizer is divided into three parts；It B, will be in the urea and first part of molten slot of phosphorus ammonium mixing addition urea in composite fertilizer 25 15 5；C, potash fertilizer, calcium powder and second part of phosphorus ammonium are added in level-one mixing channel, and urea is melted into the mixture in slot and is squeezed into level-one mixing channel；D, monoammonium, dry ammonium and third part phosphorus ammonium are added in two level mixing channel, and the mixture in level-one mixing channel is squeezed into two level mixing channel；E, the mixture in two level mixing channel is squeezed into sprinkling pelleting machine, is completed by high tower cooler, i.e. high-tower melting granulation after the completion of granulation.The present invention is suitable under 6 September south high humidity hot environments, by technique adjustment, so that slurry slurrying is uniformly mixed and is granulated sprinkling uniformly, improve balling ratio and cooling effect, effectively prevent fertilizer adhesion bottom of tower.
Description
Technical field
The present invention relates to fertilizer manufacture fields, and in particular to high-tower melting granulation technique under a kind of high humidity high-heat environment.
Background technology
Currently, high tower smelting process is affected by weather humidity and temperature, factory of many high tower meltings composite fertilizer is forced in
Summer stops production, and summer is the crucial moment for producing Autumn-sown wheat fertilizer.High tower melts composite fertilizer's slurry from differential comminutor spray orifice
Middle injection, under the action of gravity, surface tension, air drag, composite fertilizer's fluid column fragments into drop, drop size and spray orifice ruler
Very little, nozzle rotary speed and slurry physical property are related.Drop side contraction edge during decline cools down, and becomes approximation when dropping down onto bottom of tower
Spherical particle.On tower in descent, decline initial stage forms drop and shrinks cooled and solidified composite fertilizer's slurry, and declines the later stage
Fertiliser granulates show hygroscopicity, particle surface easily moisture absorption under high humidity hot conditions, are particularly easy to viscous bottom of tower.
Invention content
The purpose of the present invention provides high-tower melting granulation technique under a kind of high humidity high-heat environment aiming at above-mentioned deficiency.
The present invention is as follows：
A, the phosphorus ammonium of composite fertilizer 25-15-5 raw materials total amount 29% is divided into three parts, first part of phosphorus ammonium is composite fertilizer's 25-15-5 raw materials
The 5% of total amount, second part of phosphorus ammonium are the 12% of composite fertilizer 25-15-5 raw material total amounts, and third part phosphorus ammonium is composite fertilizer's 25-15-5 raw materials
The 12% of total amount；
B, by the urea and first part of molten slot of phosphorus ammonium mixing addition urea in composite fertilizer 25-15-5, urinating temperature in molten slot is
115-125℃；
C, potash fertilizer, calcium powder and second part of phosphorus ammonium being added in level-one mixing channel, temperature is 105-110 DEG C in level-one mixing channel, and
Urea is melted the mixture in slot to squeeze into level-one mixing channel；
D, monoammonium, dry ammonium and third part phosphorus ammonium are added in two level mixing channel, and temperature is 95-100 DEG C in two level mixing channel, and by one
Mixture in grade mixing channel is squeezed into two level mixing channel,
E, the mixture in two level mixing channel is squeezed into sprinkling pelleting machine, outer 29 revs/min of the rotary speed of sprinkling pelleting machine sprays simultaneously
10-20 revs/min of rotary speed in comminutor is drenched, is completed by high tower cooler, i.e. high-tower melting granulation after the completion of granulation.
The urea melts slot, level-one mixing channel and two level mixing channel and is all made of steam heating.
It is an advantage of the invention that：1, stable yields brings benefits under summer high humidity hot conditions；2, technique adjustment is simple, be not required into
Row equipment technological transformation；3, prilling temperature reduces, and fertiliser granulates is made to be easy to cooling fixed line, and granule strength improves；4, two level mixing is reduced
Slot steam consumption, effectively reduces cost；5, finished granule rate improves, and effectively prevent viscous bottom of tower.The present invention is suitable for the month south 6-9
Under high humidity hot environment, by technique adjustment, so that slurry slurrying is uniformly mixed and to be granulated sprinkling uniform, improve balling ratio and
Cooling effect effectively prevent fertilizer adhesion bottom of tower.
