Abstract
The invention provides a triammonium phosphate composite fertilizer and its making process, wherein the composite fertilizer comprises (by weight portion) urea 30-40 parts, potassium chloride 28-35 parts, phosphoric ammonium 28-35 parts, ammonium chloride 3-5 parts.
Description
Technical field:
The present invention originally relates to a kind of triammonium phosphate composite fertilizer and technology of preparing thereof.
Background technology:
At present, be used for all kinds of composite fertilizers (mixing fertile) of farm crop, its raw materials for production mainly contain Repone K, vitriolate of tartar, monoammonium phosphate, diammonium phosphate, calcium superphosphate, ammonium chloride, bicarbonate of ammonia, urea etc.In order to produce total nutrient content, must adopt the method that improves phosphorus ammonium use proportioning to realize at the fertilizer more than 50%.In order to be fit to the actual needs of crop growth, simple dependence uses urea to improve the content of single nutrients of nitrogen, has not obviously satisfied scientific formula fertilising requirement.Simultaneously because the composite fertilizer that traditional prilling process is produced (mixing fertile) and since its granulation process belong to simple physics sticking and, structure is more open, the fertilizer dissolving discharges very fast, fertilizer efficiency is decomposed and is run off soon, utilization rate of fertilizer is lower.
Summary of the invention
The object of the invention is to improve the shortcoming of existing composite fertilizer production technology, and a kind of triammonium phosphate composite fertilizer and manufacture method thereof are provided, and for achieving the above object, the present invention takes following design:
Preparation process adopts raw material monoammonium phosphate, the excessive ammonification of diammonium phosphate, degree of neutralization reaches the ammonification synthesis technique of 1.3---1.5, prepare the triammonium phosphate mixed slurry that meets processing requirement, add the triammonium phosphate stablizer then, to guarantee that triammonium phosphate keeps relative stability, and reduces its decomposition course in follow-up composite fertilizer manufacturing processed as far as possible.
Step 1: from the phosphoric acid ammonification and after the operation of preparation ammophos (monoammonium phosphate and diammonium phosphate mixture), with the mixed slurry cover high pressure excessive ammonification device of making a gift to someone.Mixed slurry, through tubular reactor, (NH3) carries out excessive ammonification with the raw material gas ammonia.Gas ammonia pressure 0.3---0.6Mpa, 60---80 ℃ of temperature control.Make phosphorus ammonium mixed slurry.
Step 2: phosphorus ammonium mixed slurry, when reaching gas-liquid solid phase balance, after ammonia saturation ratio (degree of neutralization) reaches technology 1.3---1.5 after testing, be pressed into automatically in the dashpot, add 3----5 part ammonium chloride and 10-18 part urea etc. again as the triammonium phosphate stablizer.
Step 3: then with being pumped in the cylinder tablets press; raw materials such as 28----35 part Repone K (vitriolate of tartar) of sending here with burden process, 20----25 part urea mix the back granulation again; pass through dryer again; equipment such as sieve apparatus, cooler, and then the process metering packing makes the triammonium phosphate efficient compound fertilizer.
The composition of triammonium phosphate of the present invention composite fertilizer: (weight proportion)
Urea: 30～40 parts
Repone K: 28～35 parts
Phosphorus ammonium: 28～35 parts
Ammonium chloride: 3---5 part
Preparation process guarantees that triammonium phosphate does not decompose, and by the interaction between the various nutrients, forms the stable nutrient unit of isostatic.Such fertilizer monomer, the double salt Solid solution of forming by multiple salt fusion.The compound manure of the present invention's preparation is on the microcosmic molecular level, with raw materials such as urea, Repone K, triammonium phosphate, diammonium phosphate, monoammonium phosphate, vitriolate of tartar, be fused into an organic nutrient integral body,, form the stable nutrient unit of isostatic by the interaction between the various nutrients.Its main component can be seen as: double salt sosoloid such as urea, urea ammonium phosphate, ammonium chloride potassium, ammonium-potassium sulfate, ammonium-potassium phosphate, triammonium phosphate, Tripotassium phosphate, ammonium syngenite.
This triammonium phosphate composite fertilizer can continuously discharge nutrient according to the absorbing state to Different Nutrients in each vegetative period of farm crop, is made for thing and absorbs, thereby reduce the decomposition loss of fertilizer in the farmland, improves chemical fertilizer utilization ratio.
The present invention prepares triammonium phosphate composite fertilizer, the characteristics of a maximum adopt the excessive ammoniation process of high pressure exactly in preparation process, with raw material monoammonium phosphate, the excessive ammonification of diammonium phosphate, after its process reaches and balances each other, generate the triammonium phosphate component of stable content, thereby improved the nitrogen content in the system.
The present invention prepares triammonium phosphate, decomposes at normal temperatures and pressures in order to prevent it, and done special processing especially in preparation process, has promptly added an amount of ammonium chloride NH
4Cl and urea CO (NH
2)
2Deng as stablizer.
The present invention prepares triammonium phosphate, decomposes in a large number in separating purification process in order to prevent it, and this technology is under the prerequisite that does not change product use proterties, preferential employing is not done to separate and is purified, but directly send into next process, and carrying out mixing granulation, oven drying at low temperature is handled.
The triammonium phosphate composite fertilizer of the present invention preparation, the raw material that adopts in preparation process is monoammonium phosphate, diammonium phosphate, can save in the phosphoric acid and former process such as ammonification, thereby can save a large amount of duplicate construction investments.Also can on original ammonium phosphate production equipment, transform, produce efficient nitrogen-phosphorus-potassium compound fertilizer.
The present invention is fit to preparation high nitrogen content, high density, high-quality universal composite fertilizer.
