Abstract
The invention relates to a high-nitrogen, high-phosphorus and high-potassium chlorine-based compound fertilizer and a preparation method thereof. The preparation method includes feeding urea, monoammonium phosphate, potassium chloride and ammonium sulfate into a granulator, subjecting stream, sulfuric acid and liquid ammonia to reaction to obtain high temperature slurries, injecting the slurries into a material layer of the granulator, subjecting materials to rolling to obtain fertilizer balls, and subjecting the fertilizer balls to drying at the temperature of 150 DEG C to 155 DEG C, cooling, screening, film coating, bin entering and packaging to obtain the compound fertilizer, wherein the mass content of total nutrients is over 54%, the nutrient content is high, and acidity and alkalinity of the materials are reasonably collocated to prevent soil from being acidified and hardened, so that the requirements of general soil can be satisfied, the application of the compound fertilizer to acid soil is facilitated, the soil is improved, and yields of crops are increased.
Description
Technical field
The present invention relates to the fertile preparation method of a kind of compound, be specifically related to a kind of high nitrogen, high phosphorus, high potassium chloro compound fertilizer and working method thereof.
Background technology
At present, two covering devices that compound is fertile are in the fertile production process of compound, for balling-up that promotes material and the adjustment of supporting part add the part clay in material; The high-content of fertilizer accomplishes 51%, and former product still is that appearance color is all not ideal enough from the particle slickness of product, and the scope of application is narrow; The agriculture demand that can not adapt to current fast development brings certain influence for the sale and the price of product, and former simple use steam granulation method is produced; Balling ratio is low; Dust is big, and content is low, and it is fertile to produce high-load compound.
Summary of the invention
The objective of the invention is for overcoming the deficiency of above-mentioned prior art, a kind of high nitrogen, high phosphorus, high potassium chloro compound fertilizer and preparation method thereof are provided, present method is implemented convenient; The constant product quality of gained, prevented from caking; The use of topdressing to adapt to Various Seasonal, different crops is carried out scientific matching according to regulation of fertilizer requirement and the fertilizer characteristic of farm crop, and nutrient is complete, the slow Ji mutually of speed; Supply fertile equilibrium, lasting fertilizer effect.Both reduced production cost and increased the fertile attraction of compound, having practiced thrift resource has again increased the performance of enterprises.
The technical scheme that the present invention takes is:
A kind of high nitrogen, high phosphorus, high potassium chloro compound fertilizer, the monoculture of nitrogen, phosphorus, potassium divides mass content all more than 18%, and the total nutrient mass content is more than 54%.
The preparation method of described high nitrogen, high phosphorus, high potassium chloro compound fertilizer comprises that step is following:
(1) by weight than taking by weighing 24 parts of urea 28-32 parts, monoammonium phosphate 35-40 part, Repone K 26-30 part, ammonium sulfate; Urea, monoammonium phosphate, Repone K, ammonium sulfate are sent into tablets press; Water vapor, the gentle ammonia react of sulfuric acid (mass concentration 60%-70%) are generated the high temperature slip injectant bed of material; Material is through rolling into the fertilizer ball, and the fertilizer ball is dried under 150-155 ℃ of temperature, cooled off;
(2) cooled particle gets into the sieve apparatus screening, and the scalping aperture is that 4.2mm dusting cover aperture is 3.0mm;
(3) with particle with coating agent coating, warehouse entry, the packing.
The mass ratio of described water vapor, gas ammonia, sulfuric acid and material is 40-60:5-8:2-3:100.
Described monoammonium phosphate uses three peaceful board monoammonium phosphates.
Described coating agent is conventional anti-hard caking agent, the preferred high-fall anti-hard caking agent of separating.
Compared with prior art, the invention has the beneficial effects as follows:
1, the product that utilizes this invention technology to produce can improve compound fertile content and prevented from caking, produces total nutrient and reaches 54%, and the monoculture branch reaches respectively more than 18%, can satisfy the 18 sign requirements of nitrogen 18～phosphorus 18～potassium, National standard; Because the acid-basicity collocation rationally can not make soil acidification, harden in the material, can not only adapt to the general soil requirement, more helps being administered in the acid soil, improves soil, increases crop yield; The product that utilizes this invention technology to produce have quality evenly, the good whiteness of color and luster degree reaches more than 74, intensity is big, can meet the need of market.
2, this working method is implemented conveniently, less investment, instant effect.This method can be brought up to more than 54% by the content (nitrogen 18%, phosphorus 18%, potassium 18%) that compound is fertile fully, produces through the adjustment back, can reach stable and high yields.The existing product structure of the company that enriched forms self high-end product, and economic benefit and social benefit are obvious.

Embodiment
Through specific examples the present invention is further set forth below, should be noted that following explanation only is in order to explain the present invention, its content not to be limited.
Embodiment 1
Urea, monoammonium phosphate, Repone K, ammonium sulfate are got into tablets press according to quality proportioning urea 30.6%, monoammonium phosphate 37.6%, Repone K 29.1%, ammonium sulfate 2.7% through the balanced material loading of high-tech microcomputer control electronics scale; Generate the high temperature slip injectant bed of material through water vapor, sulfuric acid and liquefied ammonia reaction; Material is through rolling balling-up; Get into dryer again and dry, the hot blast temperature that this moment, dryer was advanced in control is at 150-155 ℃.Material through the screening of 4.2 ㎜-3.0 ㎜, carries out coating entering stockyard bulk bin cooling moisture content of finished products and is controlled at 1.3 behind secondary drying, and the material temperature is packed below 28 ℃ again.
Embodiment 2
Urea, monoammonium phosphate, Repone K, ammonium sulfate are got into tablets press according to quality proportioning urea 32%, monoammonium phosphate 37.9%, Repone K 27.0%, ammonium sulfate 3.1% through the balanced material loading of high-tech microcomputer control electronics scale; Generate the high temperature slip injectant bed of material through water vapor, sulfuric acid and liquefied ammonia reaction; Material is through rolling balling-up; Get into dryer again and dry, the hot blast temperature that this moment, dryer was advanced in control is at 150-155 ℃.Material through the screening of 4.2 ㎜-3.0 ㎜, carries out coating entering stockyard bulk bin cooling moisture content of finished products and is controlled at 1.3 behind secondary drying, and the material temperature is packed below 28 ℃ again.
Comparative Examples
With urea, monoammonium phosphate, Repone K, ammonium sulfate according to quality proportioning urea 46.4%, monoammonium phosphate 58%, Repone K 62%, ammonium sulfate 20%; The granulation of back entering tablets press stirs; Dryer is dried, and the hot blast temperature that this moment, dryer was advanced in control is at 150 ℃-155 ℃.Material is obvious through the high-temperature hot-air evaporation secondary balling-up of dryer, causes out the particle of dryer bigger, and effect is undesirable.It is unbalanced to support part control.
