Abstract
A process for preparing the modified ammonium hydrogen carbonate compound fertilizer with phosphorus includes such steps as calcining dolomite to obtain magnesium oxide, grinding it into fine powder, mixing it with ammonium hydrogen carbonate to obtain ammonium magnesium phosphate hexahydrate, covering it on the ammonium hydrogen carbonate crystal to prevent the ammonium hydrogen carbonate from absorbing external water, and mixing it with potassium chloride.
Description
The present invention is the manufacturing process that belongs to a kind of Nitrogen-Phosphorus-Potassium compound fertilizer.
In prior art, for example No. 896284 patents of Britain are described, and it is a kind of suitable fertilizer that Israel's fertilizer chemical company is introduced bicarbonate of ammonia, can divide voluntarily to be situated between for ammonia, carbonic acid gas and water, do not accumulate positively charged ion and negatively charged ion in soil.This characteristic that is situated between of dividing voluntarily, make bicarbonate of ammonia be difficult to transportation and storage, lose useful nitrogen, and the dividing potential drop height of ammonia in the air above the salt, making has stimulation to the people when carrying, salt also lumps easily, and should not remove with common farm implements and broadcast, damage because farm implements subject to corrosion, the material that itself has a fertilizer efficiency with another kind in No. 896284 patents of Britain mixes handles bicarbonate of ammonia, thereby make caking and divide the trend that is situated between to be solved voluntarily, just with di(2-ethylhexyl)phosphate magnesium (MgHPO
4) add in the bicarbonate of ammonia, the two is blending in proportion, and the ammonia that it begins immediately with bicarbonate of ammonia divides Jie voluntarily and emitted combines, and generates ammonium magnesium phosphate six hydrate (MgNH
4PO
46H
2O), though can improve the bicarbonate of ammonia anti-caking like this, and reduce branch Jie trend, do not satisfy agriculture requirement of going up to ternary composite azophoska.
The objective of the invention is easily to divide the caking that is situated between, cause the shortcoming of nitrogen damage and bale broken to improve, make the physical property of bicarbonate of ammonia and stability be more suitable for the requirement of agricultural fertilizer, and can satisfy agricultural and go up fertile again requirement at bicarbonate of ammonia.
Design of the present invention is to be to contain free-water at one of unsettled principal element of bicarbonate of ammonia, have only these free-waters are removed, could improve its stability, the method for reduction free water content commonly used is to add anion active agent to increase crystalline particle, perhaps uses the method for air stream drying.The present invention utilizes to add additive ammonium phosphate (NH
4H
2PO
4) and magnesian air stream drying method, making the free-water in the bicarbonate of ammonia become crystal water, thereby improve stability, the additive monoammonium phosphate itself is a kind of high concentration N phosphorus composite fertilizer, can be made into the compound manure based on bicarbonate of ammonia.The raw material that the present invention adopts is aboundresources rhombspar (CaCO cheap and easy to get
3, MgCO
3), pulverize through jaw crusher, the rhombspar roasting after pulverizing, maturing temperature is 950～1100 ℃, material magnesium oxide will be worn into fine powder after the roasting, generally wears into mesh diameter and be 60～100 microns fine powder, powder particulate phosphoric acid one ammonium, magnesium oxide and bicarbonate of ammonia blending then, make the modified ammonium bicarbonate compound manure that phosphorates, the blending process generates with ammonium magnesium phosphate six hydrate.Its reaction formula is as follows:
MgO+NH
4H
2PO
4+5H
2O→MgNH
4PO
4·6H
2O
According to the needs of Different Crop, also can evenly mix in proportion with Repone K becomes ternary composite azophoska.General N: the P that adopts
2O
5: K
2O=1～1.5: 1: 0～1(weight).
Effect of the present invention is to make bicarbonate of ammonia divide the free-water that is situated between to become crystal water, be fixed in the ammonium magnesium phosphate double salt, so just reach and reduce free water content in the multiple fertilizer, and the double salt that generates can cover the ammonium bicarbonate crystal outside, stop bicarbonate of ammonia to absorb extraneous moisture, keep stability.Prepared so multiple fertilizer product outward appearance drying is loose, prevented from caking, and stability improves more than 8 times than general bicarbonate of ammonia.Still keep dry after following 16 hours through the condition of 35 ℃ of humidity 64%, good fluidity, (pressure is 0.28 kilograms per centimeter behind the briquette test to stand 15 days
2), the modified ammonium bicarbonate that phosphorates is still very dry, does not lump good fluidity.
According to understanding from 40,000 tons of bicarbonate of ammonia small fertilizer plants of existing annual output, annual because of storing bale broken with a toll of 100,000 yuan, produce about 3,000 ten thousand tons of bicarbonate of ammonia per year in national small nitrogenous fertilizer plant in 1984, then because of storing bale broken with a toll of 8,000 ten thousand yuan, then can avoid above-mentioned loss if make of the present invention phosphorating with general bicarbonate of ammonia during modified ammonium bicarbonate, benefit reaches 8,000 ten thousand yuan/year.
Be most preferred embodiment of the present invention below:
Embodiment 1, and 950 ℃ of roastings, 12.64 kilograms of magnesium oxide of generation are worn into 80 microns of mesh diameters rhombspar, then with 28.4 kilograms of powder particulate phosphoric acid one ammoniums, 100 kilograms of phase blending of bicarbonate of ammonia can make drying and not lump, and the multiple fertilizer of good fluidity wherein contains N14%(weight), P
2O
510%(weight), its stability improves more than 8 times than general bicarbonate of ammonia.
Embodiment 2, rhombspar 950 ℃ of roastings, 12.64 kilograms of magnesium oxide that generate are worn into 80 microns of mesh diameters, then with 36.8 kilograms of powder particulate phosphoric acid one ammoniums, 100 kilograms of phase blending of bicarbonate of ammonia, can make the identical multiple fertilizer of outward appearance, stability and embodiment 1, wherein contain N13.5%(weight), P
2O
