Abstract
The present invention discloses an organic diammonium phosphate fertilizer and its production method. It is mainly formed from diamonium phosphate and small quantity of monoammonium phosphate, and it also contains organic material whose content is 0.5-10%, said organic material is humic acid whose content is 0.5-5%. Its production method is characterized by that in the existent slurry method and in the production process for producing diammonium phosphate the organic material solution can be added, and its production is implemented on basis of monoammonium phosphate production equipment. Said fertilizer has obvious fertilizer effect slowly-releasing action, can prolong fertilizer effective period, and can raise nitrogen content to above 15%, can effectively raise nitrogen utilization rate and can improve soil texture, etc.
Description
Technical field the present invention relates to a kind of production technique of fertilizer, is specifically related to organic phosphoric acid two ammonium fertilizers and production method thereof.
The inorganic fertilizer product of background technology China rural area life-time service, as monoammonium phosphate, diammonium phosphate, only contain inorganic nutrients in its product, long-term application causes soil compaction, crops quality to descend, and monoammonium phosphate and two ammonium products in use nitrogen loss is big, utilization ratio is on the low side; In the production technique of existing slurry process diammonium phosphate inorganic fertilizer, nitrogen content generally maintains about 13%, will up promote very difficulty of nitrogen content again, and often has ammonia to overflow in process of production environment is polluted.
Summary of the invention the present invention provides a kind of organic phosphoric acid two ammonium fertilizers and production method thereof in order to overcome the above deficiency of existing diammonium phosphate inorganic fertilizer in production process and use.
Technical scheme of the present invention is:
A kind of organic phosphoric acid two ammonium fertilizers mainly are made up of diammonium phosphate and a spot of monoammonium phosphate, and it also contains the organism that content is 0.5-10%.
Organism in the described fertilizer is a humic acids, and content is 0.5-5%, and fertilizer is coffee-like.
Organic phosphoric acid two ammonium fertilizer production methods are to add organic solution in existing slurry process features of DAP production technological process.
In aforementioned production method, the organism that is added is a humic acids, adds in neutralization reaction process or concentration process.
Organic content in the described fertilizer is 1%.
The present invention produces organic phosphoric acid two ammonium fertilizers on the basis of MAP Plant, the equipment that need improve or add is few, expense is little; This kind diammonium phosphate fertilizer has tangible fertilizer efficiency and releases slow effect, prolongs fertilizer efficiency period; Can improve more than the nitrogen content to 15%, effectively improve nitrogen use efficiency; Can improve the soil soil property, improve the soil comprehensive fertility.
The invention will be further described below in conjunction with accompanying drawing for description of drawings:
Fig. 1 is prior art (slurry process) production diammonium phosphate process flow sheet.
Fig. 2 is a process flow sheet of the present invention.
Embodiment (referring to Fig. 1), the technical process of prior art are that the mid low grade phosphate rock with China is a main raw material, produce diammonium phosphate product.Phosphorus ore slurry (or ground phosphate rock) makes phosphoric acid by wet process (concentration 17-25%P with the excess sulfuric acid reaction
2O
5), again with the gas ammonia neutralization reaction, make phosphorus ammonium solvent or diluent slurry, through the secondary ammonification, concentrate, dry, granulation makes diammonium phosphate product.
(referring to Fig. 2), the phosphoric acid finished product in the process flow sheet of the present invention have two kinds of modes to obtain: a kind of is to be main raw material with the mid low grade phosphate rock, makes the phosphoric acid finished product with the reaction of excess sulfuric acid slightly, and another kind is directly to buy the phosphoric acid finished product.After obtaining qualified phosphoric acid finished product, the operation of processing organic diammonium phosphate fertilizer is: feed gas ammonia and produce neutralization reaction in phosphoric acid solution, to neutralizing well (or thickener) in, feed simultaneously organic solution, make organic phosphoric acid two ammonium fertilizers through secondary ammonification, concentrated, drying, granulation, screening again.Organism of the present invention is humic acids, Sodium salts humic acids, zinc humic acid, brown coal etc.
The organic solution of above-mentioned operation is earlier with after the organic substance dissolving, in the adding neutralizing well (or thickener); The organic substance of present embodiment is best with the humic acids.Be tart humic acids and ammonia react and generate humic acids ammonia, it has nitrogen fixation, increases nitrogen content.
If prepare phosphoric acid solution, then take production technique same as the prior art and equipment with Rock Phosphate (72Min BPL).The one, because this production technique comparative maturity, the phosphoric acid solution steady quality of preparation, the 2nd, because can utilize original equipment and device, need to improve and the equipment that adds is few, expense little, reduce investment outlay.
In the present embodiment, behind the adding humic acids, through reaction, it is unique coffee-like that the color of organic phosphoric acid two ammonium fertilizers of generation is, and is different from traditional white.Wherein organic content is 0.5-10%, as the organism that adds be humic acids then its content be 0.5-5%.
Through multiple authentication, be that 50% humic acids is an example with purity, to arrive 0.5% as the organic content in organic phosphoric acid two ammonium fertilizers that generate, then the amount of the humic acids that need add is about 1: 100 with the ratio of the amount of diammonium phosphate; Will arrive 1% as the organic content in organic phosphoric acid two ammonium fertilizers that generate, then the amount of the humic acids that need add is about 1: 50 with the ratio of the amount of diammonium phosphate; Will arrive 5% as the organic content in organic phosphoric acid two ammonium fertilizers that generate, then the amount of the humic acids that need add is about 1: 10 with the ratio of the amount of diammonium phosphate.
