Abstract
The invention discloses a process for preparing a nitro-sulfenyl polypeptide compound fertilizer, mainly comprising the following steps of: 1, metering ammonium nitrate through a metering scale according to a mixture ratio, conveying to a melting device through a bucket elevator so that the ammonium nitrate is molten into molten liquid, then, conveying the molten liquid to a mixing tank at a tower-top granulation post through a pressure pump feeding into a granulating machine through an overflow pipe and granulating; 2, respectively conveying monoammonium phosphate, sylvite and a filling agent to the metering scale through an elevator, metering and then conveying to a mixing belt, crushing, conveying to a heater through the elevator and then conveying to the mixing tank; and 3, conveying metalloprotease to the metering scale through the elevator, metering and then conveying to the mixing tank, mixing the metalloprotease with the nitramine molten liquid, the monoammonium phosphate, the sylvite and the filling agent powder in the mixing tank to form slurry, conveying the slurry into a granulation tower and granulating to obtain the nitro-sulfenyl polypeptide compound fertilizer. The compound fertilizer prepared by the process disclosed by the invention has high utilization rate; the thermal energy of the round molten ammonium nitrate can be sufficiently utilized in the granulating process; a drying process is unnecessary; no three wastes is discharged; and therefore the process is a clean production process.
Description
Technical field
The invention belongs to the agrochemical technical field, a kind of specifically nitre sulfenyl polypeptide composite fertilizer preparation technology method.
Background technology
Farm crop need tens kinds of essential nutritive elements, and wherein main element is nitrogen, phosphorus, three kinds of elements of potassium.That at present China produces is nitrogenous, the fertilizer ratio of phosphorus, three kinds of elements of potassium is unbalanced, be lower than soil and need use the reasonable levels of nitrogen, phosphorus, three kinds of elements of potassium, and, in fertilising, very easily cause the loss of nitrogen element, cause the waste of great financial loss and fertilizer.Some composite fertilizers that provide at present besides, such as, phosphorus-ammonium compound fertilizer, ammonium nitrate fertilizer are all used traditional simple and direct production method production composite fertilizer, and this composite fertilizer of production can not satisfy the needs of agriculture production.For adapting to and satisfy the needs of agriculture production, my company works out a kind of new manufacturing nitre sulfenyl polypeptide composite fertilizer preparation technology method, composite fertilizer's utilization ratio height of this preparation technology method manufacturing, promote crop absorb, prevent fertilizer loss, improve crop yield, resources conservation, environmental friendliness, nutrient and characteristics such as can lay in.
Summary of the invention
Purpose of the present invention just provides a kind of loss that improves fertilizer utilization ratio, the absorption of promotion crop, prevents fertilizer, improves a kind of nitre sulfenyl polypeptide composite fertilizer preparation technology method of crop yield.
The preparation method of a kind of nitre sulfenyl polypeptide composite fertilizer of the present invention mainly comprises following processing step:
1, ammonium nitrate is measured by proportioning with weighing balance; by bucket elevator ammonium nitrate is delivered to the ammonium nitrate melting device ammonium nitrate is fused into the ammonium nitrate fused solution; be delivered to cat head granulation post tempering tank by pressure pump then, enter tablets press by upflow tube and carry out granulation:
2, monoammonium phosphate is delivered to weighing balance with lift and measures, the monoammonium phosphate that measures is delivered to enters the powder lift behind the batch mixing belt by proportioning:
3, sylvite is delivered to weighing balance with lift and measures, the vitriolate of tartar that measures is delivered to enters the powder lift behind the batch mixing belt by proportioning:
4, weighting agent is delivered to weighing balance with lift and measures, the weighting agent that measures is delivered to enters the powder lift behind the batch mixing belt by proportioning:
5, metalloprotease is delivered to weighing balance with lift and measures, the metalloprotease that measures is delivered to tempering tank by proportioning:
6, will enter the mixed monoammonium phosphate of powder lift, sylvite, weighting agent and be delivered to powder temperature 50-60 degree after powder well heater (the heater temperature 80-100 degree) heating by the powder lift:
7, the powder conveying after will heating mixes the formation slip with ammonium nitrate fused solution, metalloprotease at tempering tank to tempering tank in proportion by weighing balance.
8, slip enters prilling tower and carries out granulation after evenly stirring.
9, obtain finished product after the work in-process that come out of granulation sieve.
10, finished particle enters coating machine and carries out packing after coating is handled.
The significant parameter control of this technology:
Solid materials such as vitriolate of tartar, phosphorus one ammonium, weighting agent are handled the post
Monoammonium phosphate: W (N) 〉=11%, W (P2O5) 〉=44%, W (H2O)≤1.5%, granularity≤0.8mm accounts for 90%
Vitriolate of tartar: W (K2O) 〉=50%, W (H2O)≤1.5%, granularity≤0.8mm accounts for 90%
Weighting agent (rhombspar or Paris white): fineness-80 order (0.175mm) accounts for 100%, W (H2O)≤1.5%
Metalloprotease: form by poly aspartic acid 90%, ferric sulfate 0.5%, vitriolate of tartar 5%, vegetable active enzyme 4.5%
The agent of oil coating is made up of paraffin 18, alkylamine 5, S-803, mineral oil 65.
The weight part of used oil coating agent is 2
Batch mixing heating post
By technical recipe batch mixing is measured.
Batch mixing well heater Material control temperature: 80～100 ℃
Mix and the granulation post.
1, tempering tank melting charge slurry temperature is 140～180 ℃;
2, pelletizing finished product grain diameter: 1～4.5mm, the particulate of requirement＜1mm is less than 3%.
Above processing parameter is because of the difference of filling a prescription, and its processing parameter is also had any different, and usually need adjust as the case may be.
Parameter controls well to help to reduce the viscosity of slip, guarantees its flowability, reduces side reaction, reduces ammonia and decreases.
Technical characterstic:
Compare with compound manure manufacturing process commonly used, high tower prilling technology has the following advantages:
1, granulation process makes full use of the heat energy of round fusion ammonium nitrate, and the very low drying-free process of moisture content of material has been saved energy consumption greatly.
2, the qualified product particle is 97% percentage in the production, so in the production process almost there is not the returning charge amount.
3, good operational environment, three-waste free discharge belongs to process for cleanly preparing.
