Description
Technical field
The present invention relates to spray granulation field, and in particular to a kind of agricultural organic composite fertilizer slurry-spraying pelletizing work of green
Skill.
Background technology
The moisture (the liquid general name that can be vaporized) in slurry (mixture, solution and solute), by being ejected into an equipment
In, with the method for heating, taking out pressure, after vaporizing the moisture content in slurry and separating, retention will not gasify (under certain condition)
Solid form granular process and claim slurry-spraying pelletizing.Such as the final manufacturing process of phosphorus ammonium granulated fertilizer.Urea whitewashing is urea
Spray reaches in compound fertilizer granulating device after melting, reduces urea and crushes link.
Color, granularity are uneven to be reflected in slurry-spraying pelletizing fertilizer production to liquid flow rate of slurry and temperature to a certain extent
There is the big problem of high low head in control.As temperature fall certainly will cause greatly grain graininess size degree drop to fall with carbonization problem greatly
It is poor big；The high color of carbonation rate is corresponding deeply, dissolution velocity is slow；The small color of carbonation rate is accordingly shallow, dissolution velocity is very fast.With amino acid
Organic fertilizer is topic（All it is the whitewashing organic fertilizer with amino acid fermentation mostly in the market）, it is not single liquid agent, rich
Containing protein, amino acid material, nitrogenous material, other materials containing organic matter etc., thus in face of same high temperature, same section
In section, the slurry-spraying pelletizing technical process of same time, its material corruption amount of cure, humification degree, activation degree etc. differ
Cause, thus grain color, granularity non-uniform phenomenon occur, but do not influence fertilizer content quality problems.In order to obtain low concentration
Nitro-compound fertilizer, the method for having producer to use physical mixed, nitro-compound fertilizer material adds part mixes after making material, to reduce
Concentration.But this method, due to organic composite can not be carried out with nitro-compound fertilizer, can not really solve above above mentioned problem.
But the technology has Fertilizer nutrient composition low etc., the use of earth material so that effective fertility reduces in fertilizer, cost of transportation
Rise, it is unfavorable for playing the efficient fertility of composite fertilizer.
The content of the invention
It is an object of the invention to reference to actual conditions, overcome the deficiencies in the prior art, there is provided a kind of green is agricultural organic
Compound fertilizer slurry-spraying pelletizing technique, the fertilizer that the spray pelleting process obtains not only realize nitro low concentration, fertilizer rate of release
Slowly, it is and neat rich in number Ten microelements, nutrients such as the organic carbons and boron, zinc, copper included in plant organic matter, plant ash
Entirely, fertilizer is balanced, plays an important roll to promoting root growth strong sprout, activating soil, increasing of quality and production.
To achieve these goals, present invention employs following technical scheme：
A kind of agricultural organic composite fertilizer slurry-spraying pelletizing technique of green, by potassium chloride：Nitric acid=100g:40 ~ 50ml adds reactive tank
10min generation potassium nitrate is reacted under the conditions of being heated to 120-130 DEG C, then nitration mixture is formed after being mixed with isometric dilute phosphoric acid solution,
It is 1 by volume that nitration mixture is synthesized into ammonia with liquid：0.6 ~ 0.9 ratio tubular reactor react generation compound fertilizer slurry after, and
Slurry is concentrated into 90% ~ 95%, rotary drum granulator is sprayed into after concentration, 10 ~ 20% biogas slurries is added in compound fertilizer slurry, 10 ~ 20% has
Machine matter, 5 ~ 10% plant ash control its water content 25 ~ 40%, obtain composite fertilizer's granulation slurry, then spray into raw in rotary drum granulator
Into Inorganic whisker fertilizer grain.
The further restriction bright as we, described phosphoric acid,diluted is that phosphorus acid content is 2 ~ 10%.
The further restriction bright as we, the biogas slurry composition include 15 ~ 25 parts of % of poultry-dung, and poultry-dung is pig manure, ox
Any of excrement or their mixture.
The further restriction bright as we, described organic matter particle particle diameter is 5-15 mesh, and organic composition is fiber
Property stalk thing, vinasse, creeping oxalis composition, fibroid stalk thing, vinasse, creeping oxalis three mass ratio are 5 in composition:2:1.Institute
It is any of rice bran, bagasse, tea bran, wheat bran, peanut press pulp or their mixture to state fibre-bearing stalk thing.
We are bright to realize technical principle：Production technology is granulated using nitrification, secondary dechlorination, potassium chloride and nitric acid are added
Reactive tank is heated and reacted under certain condition, and certain density hydrochloric acid can be made in the HCL gases of effusion after water absorbs, generation
Potassium nitrate mixed with phosphoric acid,diluted after form nitration mixture.The nitration mixture is reacted into generation compound fertilizer in tubular reactor in proportion with synthesis ammonia
Slurry, certain proportion plant source organic matter is added, is stirred, control water content is 25 ~ 40%, then sprays into rotary drum granulator
Middle generation nitrogen, phosphorus, a certain proportion of organic compound fertilizer granules containing nitro of potassium.The composite fertilizer that this technique obtains, which has, to be granulated
Even, bright in color, steady quality, nutrient be sufficient, soluble and the features such as be absorbed by crops, and particularly makees that seed manure is relative to seed to pacify
Entirely.The multiple kinds of crops such as suitable all kinds of soil and wheat, corn, melon and fruit, peanut, vegetables, beans, flowers, fruit tree and economic work
Thing, applied suitable for base manure, seed manure, top dressing, seed manure, punching.
The present invention obtains good technique effect by such scheme：
For nitro inorganic nutrients content between 30 ~ 40%, nitro content is relatively conventional in the bright obtained Inorganic whisker fertilizer of we
Fertilizer reduces, and obtains the reduction of fertilizer rate of release, and crops can obtain sufficiently absorbing fertilizer nutrient, avoid conventional fertilizers
The problem of Nutrient Absorption is not caused to waste, is lost in entirely occurs, and improves resource utilization；The bright obtained composite fertilizer's nitro of we is low dense
Degree, and rich in the number Ten microelements such as plant organic matter, humic acid, organic carbon and boron, zinc, copper, to the abundant profit of organic matter
With making compound fertilizer nutrient complete, fertilizer is balanced, plays an important roll to promoting root growth strong sprout, activating soil, increasing of quality and production.
