Abstract
The invention relates to the technical field of compound fertilizer, specifically, a straw organic compound fertilizer and a manufacturing technique thereof. Compared with the prior art, the technique is characterized in that various straw pastes are mixed with the reactants of rock phosphate powder and nitric acid after certain treatment, and then the compound fertilizer is formed after cooling or drying and pelleting technique. The manufacturing process flow of the invention is very simple, has strong operability, and can be implemented without any very complex equipment, thus being able tobe implemented in most rural areas in the country and suitable for being popularized and used in rural areas in the country to effectively and reasonably solve the problem of organic compound fertilizer in the rural areas.
Description
Technical field
The present invention relates to composite fertilizer's technical field, particularly a kind of straw organic composite fertilizer and production technique
Background technology
In China rural area; various inexhaustible, nexhaustible abundant stalk resources are arranged, but because a variety of causes, the comprehensive development and utilization rate of stalk is extremely low; so; every harvest season, stalk just becomes burden, and a lot of stalks are by on-site incineration; both dangerous; contaminate environment again, thereby become society's one big public hazards, in recent years China to the protection environment, develop the renewable energy resources and very pay attention to.Stalk is prohibited burning, is rationally utilized stalk resource to list the important process content of governments at all levels in.The technology of utilizing stalk to make compoiste fertilizer in the prior art is ripe, China Patent No. is as has been publicly: the straw organic composite fertilizer of ZL03111215.3 and production technique, this production technique with the stalk drying and crushing after with urea, monoammonium phosphate, after mixing, make by chemical fertilizer such as Repone K, the advantage of this processing method is effectively to carry out the composition of reasonably combined chemical fertilizer to apply fertilizer targetedly at various plant, but this method also has a lot of shortcoming and defect parts, as the requirement to stalk must be exsiccant, to various raw materials also is the existing chemical fertilizer of requirement, so just increased the difficulty of processing requirement, increased cost, be unfavorable for promoting in vast rural area.
Summary of the invention
The straw organic composite fertilizer and the production technique that the purpose of this invention is to provide that a kind of flow process is simple, workable, good economy performance, result of use are good.
The object of the present invention is achieved like this: the technological process of production of straw organic composite fertilizer of the present invention is:
(1) stalk is put into airtight rotary spherical digester, feeding vapor temperature is that 120-150 degree, vapor pressure are that the boiling that 3-5 standard atmospheric pressure carries out certain hour becomes starchiness until stalk;
(2) the starchy above-mentioned substance of well-done one-tenth is spurted to feed bin,, obtain a kind of paste that contains the potassium element material by the discharge section air;
(3) putting into reactor with the nitric acid of a certain amount of and concentration, carry out stirring reaction, to obtain the compounding substances of nitrogenous and phosphoric through the rock phosphate powder of pulverizing;
(4) above-mentioned steps (2) and the prepared paste of step (3) and compounding substances are mixed and stir make mixture;
(5) mixture of step (4) gained is dried or dry;
(6) material of step (5) gained is put into tablets press and carry out granulation, package and promptly obtain the compoiste fertilizer finished product.
Compared with prior art, straw organic composite fertilizer of the present invention and production technique, with various dried or wet, through pulverizing or can obtaining useful compoiste fertilizer through just mixing with rock phosphate powder and nitric acid again after certain processing without the stalk of pulverizing, the raw material of this compoiste fertilizer is from stalk, so can be fit to the needs of most compound plant fertilizer, production technique of the present invention is very simple, workable, do not need very complex apparatus, do not need some high-quality talents yet, most of Rural areas in China just can be implemented, therefore being highly suitable for China rural area promotes the use of, can be effective, reasonably solve the compound manure problem in rural area, play one and get fertilizer on the spot, the effect of composting on the spot.
Embodiment
The production technique of straw organic composite fertilizer of the present invention has following embodiment:
With various dried or wet, through pulverizing or putting into airtight rotary spherical digester without the stalk of pulverizing, in airtight rotary spherical digester, feed a certain amount of steam, the temperature of steam is the 120-150 degree, the pressure of steam is 3-5 standard atmospheric pressure, stalk carries out certain hour in such steam boiling becomes starchiness until stalk, probably about 1 hour, practical situation are because of stalk type difference, thickness difference for cooking time, and cooking time is also different.
The starchy above-mentioned substance of well-done one-tenth is spurted to feed bin,, obtain potassium content than higher a kind of paste by the discharge section air;
Putting into reactor with the nitric acid of a certain amount of and concentration, carry out stirring reaction, to obtain nitrogen and phosphoric through the rock phosphate powder of pulverizing; Rock Phosphate (72Min BPL) order number is about the 20-50 order, the order number is the bigger the better, consumption can be according to the place of production of rock phosphate powder in the practical situation and different change of content of phosphorus, and generally about 20%, concentration of nitric acid all can change according to the place of production of Rock Phosphate (72Min BPL) is different with phosphorous situation with consumption concentration of nitric acid; Generally about 1 hour, can there be change in the reaction times of mixture in reactor according to the variation of temperature of reaction, according to different product requirements, changes different rock phosphate powders and nitric acid proportioning, to obtain the product of different nitrogen, phosphorus content;
The prepared intermediates of above method are carried out mixing and stirring;
The mixture of mixing and stirring gained is dried or dry;
Oven dry or the mixture that dries the back gained are put into tablets press and carried out granulation, package and promptly obtain the compoiste fertilizer finished product.
After testing, the total nitrogen content of the compoiste fertilizer of making by production technique of the present invention is that 0.648% (weight percent), full phosphorus are that 0.99% (weight percent), full potassium are that 17.98% (weight percent), organism are 58% (weight percent), and these indexs meet the national standard of compoiste fertilizer principal element content fully.
Each flow process of the complete processing of production compoiste fertilizer of the present invention all is very simple, requirement to equipment is not high yet, do not have strict accurate restriction for various proportion of raw materials yet,, be highly suitable for vast rural area and promote because just not high to the technical level of operators requirement yet.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
