When manufacture compound fertilizer granules are switched to manufacture urea granules, the shower nozzle of comminutor 9 is changed.
The step of producing high tower compound fertilizer, including：
Step one：74% urea liquid is under the control of one-level urea liquid liquid level gauge 13, into one-level urea liquid storage tank
1,74% urea liquid accounts for the 60%-80% of the liquid level of one-level urea liquid storage tank 1.
74% urea liquid refers to the aqueous solution of urea that mass fraction is 74%.
The present invention uses the raw material for not being frozen into the urea liquid of urea granules as generation composite fertilizer, multiple in existing production
In the process in Hefei, use by urea liquid solidify after the urea granules that are formed as raw material, urea granules also need into
Row reheating（Heating-up temperature is more than 100 DEG C）It is changed into urea liquid, can be produced during urea granules reheating
Raw biuret, and the present invention directly using the urea liquid for not being frozen into urea granules as raw material, can save to urea granules
The step of reheating, so as to reduce the generation of biuret, making the content of biuret in composite fertilizer substantially reduces.
During one-level urea liquid storage tank 1 conveys 74% urea liquid to two grades of urea liquid storage tanks 2, one-level urine
74% urea liquid in plain solution reservoir 1 remains liquid level in 60%-80%.
Step 2：74% aqueous solution of urea in one-level urea liquid storage tank 1 is pumped into two grades by one-level urea solution pump 10

During urea liquid, by evaporation thermometer 15 by the temperature control of urea liquid vapo(u)rization system 3 at 125 ~ 130 DEG C, urine
The evaporation time of plain solution vapo(u)rization system 3 was controlled at 7 ~ 10 minutes.
99% urea liquid refers to the aqueous solution of urea that mass fraction is 99%.
In order to ensure influence of the composite fertilizer to the demand of urea liquid and reduction product quality, should try one's best reduction by 74%
Urea liquid enters the residence time of urea liquid vapo(u)rization system 3, and evaporation moisture need to be typically completed in 7-10 minutes, is produced
99% urea liquid, for needed for composite heat transfer.
Step 5：By fusing urea solution pump 12 under the control of urea liquid flowmeter 16, by 30 ~ 50 parts by weight
99% urea liquid is pumped into one-level blender 5；Meanwhile, phosphorus potassium raw material weighing system 4 sends into the potash fertilizer of 5 ~ 20 parts by weight described
In one-level blender 5, uniformly mixed with 99% urea liquid of 30 ~ 50 parts by weight；Wherein, during mixing, pass through
One-level mixing temperature meter 17 is by the temperature control of one-level blender 5 at 120 ~ 130 DEG C.
By the temperature control to one-level blender 5, the generation of biuret can be further reduced.
Urea liquid flowmeter 16 is mass flowmenter, and the function with control control valve can control the size of flow.
Step 6：The mixed liquor of urea liquid and potash fertilizer in one-level blender 5 enters secondary mixer 6 by pipeline；
Meanwhile, phosphorus potassium raw material weighing system 4 sends into the phosphate fertilizer of 1 ~ 30 parts by weight in secondary mixer 6, with urea liquid and potash fertilizer
Mixed liquor is uniformly mixed；Wherein, during mixing, by two grades of mixing temperature meters 18 by the temperature of secondary mixer 6
Degree control is at 110 ~ 128 DEG C.
By the temperature control to secondary mixer 6, the generation of biuret can be further reduced.
Step 7：Potash fertilizer, phosphate fertilizer in secondary mixer 6 are entered with the mixed liquor of urea liquid by pipeline uniformly to be mixed
Device 7 is uniformly mixed.
Temperature control in homo-mixer 7 is at 110 ~ 128 DEG C.
Step 8：Mixed liquor in homo-mixer 7 enters comminutor 9 by pipeline, and mixed liquor is in granulation tower 8 with liquid
Drop mode freely falling body falls and natural cooling is solidified into high tower compound fertilizer particle.
The size controlling scope of high tower compound fertilizer particle is：2.0-4.2mm.
The step of producing urea, including：
Step one：74% urea liquid is under the control of one-level urea liquid liquid level gauge 13, into one-level urea liquid storage tank
1,74% urea liquid accounts for the 60%-80% of the liquid level of one-level urea liquid storage tank 1.
Step 2：74% aqueous solution of urea in one-level urea liquid storage tank 1 is pumped into two grades by one-level urea solution pump 10
Urea liquid storage tank 2,74% urea liquid accounts for two grades of liquid levels of urea liquid storage tank 2 in the case where two grades of urea liquid liquid level gauges 14 are controlled
60%-80%.
Step 3：74% urea liquid in two grades of urea liquid storage tanks 2 is pumped into urea liquid by urea solution pump 11 and steamed
Hair system 3.
Step 4：74% urea liquid is flashed to 99% urea liquid by urea liquid vapo(u)rization system 3；Wherein, in evaporation 74%
During urea liquid, by evaporation thermometer 15 by the temperature control of urea liquid vapo(u)rization system 3 at 125 ~ 130 DEG C, urine
The evaporation time of plain solution vapo(u)rization system 3 was controlled at 7 ~ 10 minutes.
Step 5：99% urea liquid is pumped into comminutor 9 by fusing urea solution pump 12, and mixed liquor is in granulation tower 8
It is interior that with drop form freely falling body whereabouts, simultaneously natural cooling is solidified into urea granules.
The size controlling scope of urea granules is：0.85-2.85mm.
When producing urea granules, therefore urea liquid, the first stop valve 19 is closed, and stops without mixed fertilizer
Phosphorus potassium raw material weighing system 4, one-level blender 5, secondary mixer 6, homo-mixer 7 are worked, and the second stop valve 20 is opened,
99% urea liquid that urea liquid vapo(u)rization system 3 is evaporated is pumped directly into comminutor 9 by fusing urea solution pump 12 and made
Grain；When producing high tower compound fertilizer, urea liquid needs mixed fertilizer, therefore, the first stop valve 19 is opened, and restart phosphorus potassium
Raw material weighing system 4, one-level blender 5, secondary mixer 6, homo-mixer 7, mix phosphorus potassium raw material weighing system 4, one-level
Clutch 5, secondary mixer 6, homo-mixer 7 work, meanwhile, the second stop valve 20 is closed, 99% urea liquid is not passed through
Fusing urea solution pump 12 is pumped into comminutor 9, and 99% urea liquid can only be pumped into one-level mixing by fusing urea solution pump 12
Device 5.
