Description
Technical field
The invention belongs to fertilizer processing technique field, and in particular to a kind of production method of water soluble fertilizer containing amino acid.
Background technology
Water-soluble fertilizer containing amino acid refers to based on free amino acid, in ratio needed for suitable plant growth, addition
Appropriate calcium, magnesium moderate-element and manufactured liquid or solid water-soluble fertilizer.Nutrient by being added is divided into moderate-element type and micro-
Secondary element type, it is divided into pulvis and aqua by product forms, amino acid content should be not less than 10.0% (or 100g/L), moderate-element
Content should be not less than 3.0% (or 30g/L).
Water soluble fertilizer containing amino acid mainly has following purposes：Water-soluble fertilizer containing glutamic acid is produced by biology chelating
High-tech of new generation, multi-functional, environment-friendly type fertilizer.By the various nutrient elements in plant growing process, reasonably complexing exists for it
Together, crop chlorophyll content can be improved after use, strengthens crop photosynthesis, various nutrient elements can be supplemented, is met whole
Nutrient requirement in process of crop growth.Make vigorous crop stalwartness, well developed root system, dark green plump, the fruit-setting rate height in blade face, fruit swollen
It is big fast, fruit is plentiful, quality better, yield are high.And strengthen crop drought resistance, cold-resistant, the ability of disease-resistant, anti-continuous cropping.Fertilizer significantly drops
The generation of low physiological disease and soil disease, Pesticide use amount is reduced, makes quality of agricultural product and output increased.
DL- pyroglutamic acids can not be applied directly to plant, not recycling will be to ring as production L-Glutimic acid waste material
Cause tremendous influence in border.DL- pyroglutamic acids hydrolyzable is into glutamic acid, and glutamic acid has good chelant energy to metallic element
One of primary amino acid of nitrogen metabolism, significant in metabolism in power, glutamic acid or living organism, can reduce plant
The content of nitrate in object, and the photosynthesis of crops can be promoted.
At present, there has been no the related content using DL- pyroglutamic acids as the raw material of production water soluble fertilizer containing amino acid.
The content of the invention
It is an object of the invention to：The problem of can not being applied directly to plant for above-mentioned DL- pyroglutamic acids, the present invention carries
For a kind of production method of water soluble fertilizer containing amino acid.
The technical solution adopted by the present invention is as follows：
A kind of production method of water soluble fertilizer containing amino acid, step are as follows：
(1) with hydrochloric acid hydrolyzate of the hydrolysis generation containing glutamic acid occurs for DL- pyroglutamic acids；
(2) magnesia is added in hydrolyzate；
(3) pH value of the hydrolyzate after quick lime regulating step (2) processing is used as 6.0~6.5；
(4) hydrolyzate after step (3) processing is placed at 75~85 DEG C and carries out insulation chelant；
(5) hydrolyzate after step (4) chelant is filtered, takes the clear liquid after filtering, it is as water-soluble containing amino acid
Fertilizer.
Further, in step (1), the concentration of hydrochloric acid is that the weight ratio of 10%, DL- pyroglutamic acids and hydrochloric acid is 1:2.
The hydrolysis of DL- pyroglutamic acids is difficult to carry out only with water, therefore, is mixed and heated, can made using hydrochloric acid and DL- pyroglutamic acids
DL- pyroglutamic acids smoothly hydrolyze in acid condition.
Further, in step (1), DL- pyroglutamic acids hydrolyze 4h with hydrochloric acid under slight boiling condition.Slight boiling condition can accelerate
Hydrolysis, and improve percent hydrolysis.
Further, in step (2), the weight of magnesia is the 5~10% of DL- pyroglutamic acid weight.The content range
Interior magnesia can ensure that the moderate-element content of the ultimogenitary water soluble fertilizer containing amino acid is not less than 3.0%, and have
Absorbed beneficial to crop, the nutrient requirement in process of crop growth can be met.
Further, in step (3), the pH value of hydrolyzate is adjusted using quick lime.Shadow of the pH value to chelant ties power
Strong to the chelating ability of magnesium ion in the range of sound is extremely important, and glutamic acid is 6.0~6.5 in pH value, chelating is stable.
Further, in step (4), the chelant time is 2h.Overlong time or it is too short can reduce chelation percent, 2h can be protected
Card glutamic acid has a higher chelation percent to magnesium ion.
Further, in step (5), hydrolyzate is filtered using plate and frame filter press.Plate and frame filter press is used for solid
With the separation of liquid, when mixed liquor flows through filter cloth, solid retention is on filter cloth, and gradually accumulation formed filter mud on filter cloth
Cake, and filtrate portion then penetrates filter cloth, turns into the clear liquid without solid, and plate and frame filter press can realize circulating filtration, protect
Demonstrate,prove the separating effect of solid-liquid.
Preferably, comprise the following steps that：
Step A, it is 1 by weight by the hydrochloric acid that DL- pyroglutamic acids and concentration are 10%:2 mixing, are added to reactor
In, seal charge door；
Step B, steam is opened, ensures that steam pressure is no more than 0.3Mpa, DL- pyroglutamic acids are with hydrochloric acid under vapor action
Micro-boiling hydrolyzes 4h, and after the completion of reaction, hydrolyzate is squeezed into chelant tank；
Step C, hydrolyzate is stirred, and magnesia is slowly added into chelant tank；
Step D, quick lime is added into chelant tank, the pH value for adjusting hydrolyzate is 6.0~6.5；
Step E, it is 75~85 DEG C to adjust the temperature in chelant tank, and is incubated chelant 2h；
Step F, circulating filtration is carried out to the hydrolyzate after chelant, to after without visible foreign matters, obtained filtrate is to contain ammonia
Base sour water soluble fertilizers.
The present invention reaction mechanism be：Hydrolysis：
Chelating：
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. the present invention produces water soluble fertilizer containing amino acid using DL- pyroglutamic acids waste material as raw material, provide not only
A kind of recycling approach of new DL- pyroglutamic acids, the water soluble fertilizer containing amino acid produced or one kind can be complete
The fertilizer of water is dissolved in, its nutrient is comprehensive, is easily absorbed by crops, and utilization rate reaches more than 90%, can be widely applied to set
Agricultural and green agriculture are applied, it is significant to development high-efficiency water-saving modern agriculture, popularization the Integration of Water into Fertilizer；
2. the present invention has simple production process, twice laid, reaction condition is gentle, substrate conversion efficiency is high, pollution-free useless
Gurry discharges, good product quality, the advantages that plant absorption rate is high；
3. water soluble fertilizer containing amino acid produced by the invention can be used for happiness chlorine, calcium, the crop of magnesium chemical fertilizer, including banana,
Rice, sorghum, millet, cotton, corn, wheat, peanut, soybean, tomato etc., it can also be used to aquatic products rich water, it is applied widely.
