Abstract
An antiexploding modified P (or P-K) contained ammonium nitrate as a high-quality composite fertilizer is prepared from phosphate powder, potassium salt and ammonium nitrate in the form of aqueous solution or in molten state through proportional mixing and vacuum crystallizing (or spray granulating at 160-170 deg.C).
Description
Technical field
The present invention relates to a kind of compound manure and manufacture method thereof, particularly relate to a kind of phosphorous, phosphorous potassium modification explosion-proof ammonium nitrate and manufacture method thereof with explosion-proof performance.
Background technology
Ammonium nitrate is traditional high-quality agricultural fertilizer material, it is again the main raw material of ammonium explosive, society went up the lawless person and utilized above-mentioned two characteristics of ammonium nitrate in recent years, ammonium nitrate is buied by department from the means of agricultural production, be mixed with native explosive privately, be used for illegal mining, even be used for terrorist activity, destroy resource, influence social security.National requirements is carried out modification to ammonium nitrate for this reason, makes conventional ammonium nitrate can not be used for explosive production.
Summary of the invention
The object of the present invention is to provide a kind of phosphorous, the phosphorous potassium modification explosion-proof ammonium nitrate and manufacture method thereof that can only be used as fertilizer.
Phosphorous, the phosphorous potassium modification of the present invention explosion-proof ammonium nitrate is main raw material with ammonium nitrate, add at least a phosphoric acid salt or add at least a phosphoric acid salt and sylvite, its cooperation ratio is ammonium nitrate by weight: phosphoric acid salt: sylvite=75～95: 5～25: 0～10.Wherein, phosphoric acid salt is the ammonium salt and the calcium salt of phosphoric acid, as ammonium phosphate, diammonium phosphate, ammonium polyphosphate, calcium phosphate, calcium polyphosphate etc.Sylvite is vitriolate of tartar, Repone K, saltpetre, potassium felspar sand etc.The preparation method of the explosion-proof ammonium nitrate of phosphorous, phosphorous potassium modification is a dual mode, it is in 92%～94% the aqueous ammonium nitrate solution that the first adds concentration expressed in percentage by weight with powdered acid salt, sylvite, mix, carry out vacuum crystallization according to the traditional vacuum crystallization process, prepare the phosphorous or phosphorous potassium modification of powdery explosion-proof ammonium nitrate.Solution temperature generally is controlled at 140～150 ℃, and temperature is crossed to hang down product moisture content will be increased.It two is that powdered acid salt, sylvite are added in the ammonium nitrate melt, mixes, and when 160 ℃～170 ℃ of fused solution temperature, carries out the shower nozzle granulation by the tower granulation process of tradition, makes phosphorous, the phosphorous potassium modification of particulate state explosion-proof ammonium nitrate.The temperature of ammonium nitrate melt generally is controlled at 160～170 ℃, and temperature is low excessively, will influence the granulation effect.
The advantage of the present invention's phosphorous, phosphorous potassium modification explosion-proof ammonium nitrate and manufacture method thereof is that technology is simple, compares with the multiple fertile technology of tradition, can reduce investment outlay 80%～90%, the total nutrient (N+P of the phosphorous explosion-proof ammonium nitrate of gained
