Abstract
The invention discloses a synergistic urea ammonium nitrogen fertilizer and a preparation method of same and belongs to the technical field of fertilizer processing. The synergistic urea ammonium nitrogen fertilizer includes magnesium sulfate heptahydrate, urea, ammonium sulfate and a synergistic agent which is prepared from following components, by weight, 15-20 parts of zinc sulfate, 25-30 parts of boric acid and 50-60 parts of polyaspartic acid. The synergistic urea ammonium nitrogen fertilizer is high in utilization rate, is comprehensive in nutrients, is quick in effect and is low in preparation cost and investment.
Description
Technical field
The invention belongs to fertilizer processing technique field, be specifically related to a kind of synergistic urea ammonium nitrogenous fertilizer and preparation method thereof.
Background technology
At present, when producing nitrogenous fertilizer at home and abroad, generally become fused solution by after solid urea or ammonium nitrate (ammonium nitrate phosphorus etc.) heating and melting, or directly use the fused solution after evaporation concentration, in fused solution, then add corresponding phosphate fertilizer, potash fertilizer, filler and additive make mixed slurry.Mixed slurry is sent into high tower granulator and is carried out sprinkling granulation, after screening surface treatment, obtain granular composite fertilizer.Sprayed the granulation material entering prilling tower by tablets press, from high tower decline process, interact with the air resistance risen at the bottom of tower, drop to after carrying out heat exchange with it at the bottom of tower, fall into the granule materials at the bottom of tower.
Also disc granulation technique can be adopted, during this technique is applicable to producing, the Chemical Mixed Fertilizer of lower concentration.Rotary drum granulator is a kind of forming machine that material can be manufactured specified shape.Rotary drum granulator is one of key equipment of composite fertilizer's industry, is applicable to the scale operation of hot and cold granulation and height, middle lower concentration Chemical Mixed Fertilizer.Groundwork mode is granule wet granulation, by a certain amount of water or steam, base fertilizer is fully reacted in cylindrical shell after damping, under certain liquid-phase condition, by the rotary motion of cylindrical shell, make to produce squeeze reunion balling-up, particle not circle between material particle, quality product is not high.
Also by slip (mixture, solution and solute) is ejected in equipment, by heating, the method for taking out pressure, moisture content in slip is vaporized and after being separated, the solid of can not gasify (under certain condition) of retention forms granular process and claims spray granulating.As the final manufacturing process of phosphorus ammonium granulated fertilizer.
Above granulation process is complicated, investment is large, drying temperature between 200-400 DEG C, water, electricity, coal energy consumption are high, and production cost per ton more than 150 yuan, and is not suitable for the granulation of simple nitrogenous fertilizer.
