Description

The invention relates to the field of fertilizer production and can be used to produce fertilizers used for planting agricultural and forestry crops, as well as for cultivating depleted soils and reclamation of disturbed lands.

A fertilizer is known that contains a modified natural or synthetic zeolite in the pores of which the basic L-amino acid or a mixture of basic L-amino acids is absorbed, while other components that promote plant growth can also be absorbed in the pores. A method for producing fertilizer consists in washing the zeolite with purified water, adding a solution of L-amino acids (L-amino acids) to it and keeping it under stirring for 2-4 days. The zeolite is then washed with purified water and dried in an oven at 65 ° (WO 2017/222464 A1, 12.28.2017).

The disadvantage of fertilizer is that when washing the zeolite with purified water, or any other, the cavities are saturated with this water, which reduces the sorption capacity of the zeolite, in addition, being an ion exchanger, the zeolite can interact with water molecules and when washing, some micro and macro elements, will be removed from zeolite.

Closest to the proposed is a complex fertilizer based on activated dehydrated natural zeolites, containing a mixture of solutions of humic, fulvic acids and amino acids in the pores of the zeolite in an amount not exceeding 1000 g per 1 ton of zeolite, as well as a solution of a mixture of nitrogen, phosphorus and potassium fertilizer in the pores zeolite in an amount of not more than 20 kg per 1 ton of zeolite. The method of obtaining this fertilizer consists in the fact that activated dehydrated natural zeolite, crushed to a grain size of 1-7 mm, is treated with an aqueous solution of the active components with vigorous stirring and spraying the solution with a spray gun, avoiding changing the degree of flowability of the zeolite, i.e. saturating zeolite micro- and macropores with this solution (RU 2687362 C1, 05/13/2019).

The disadvantage of this fertilizer and the method of its production is the low content of amino acids in the pores of the zeolite, due, firstly, to a small fraction of amino acids in the total amount of acids used, in addition, humic acids, having very large molecular sizes, will not enter into a synergistic compound with zeolite, they will not be able to penetrate the zeolite cavity and the desired interaction will not occur.

The technical problem solved by the invention is to obtain an organomineral fertilizer having increased efficiency, prolonged action, and also to provide the ability to introduce lower doses of fertilizer into the soil.

The technical problem is solved by organomineral fertilizer, including dehydrated zeolite with amino acids embedded in its pores, while it includes free amino acids and / or oligopeptides with a molecular size of not more than 1 nm (10 Angstroms) in an amount of 500-1800 g of amino acids per 1 ton zeolite, the porosity of the modified zeolite is from 45 to 75%, and the sizes of the cavities and channels of zeolite crystals are from 0.2 to 1 nm.

The organomineral fertilizer preferably consists of granules with a fraction size of 1-7 mm.

The mass fraction of nutrients in organic fertilizer in% in terms of dry matter is not less than:

total nitrogen 0.8 total phosphorus, in terms of P ₂ O ₅ 0.6 total potassium, in terms of K ₂ O 0.3

The technical problem is also solved by the method of producing organic fertilizer, namely, that the activated dehydrated zeolite is mixed with a sprayed aqueous solution containing amino acids, and mixed, while mixing the obtained zeolite with a distilled aqueous solution containing amino acids, is carried out using an aqueous solution containing free amino acids and / or oligopeptides with a molecular size of not more than 1 nm (10 Angstroms), with a ratio of the solution volume and the amount of zeolite at the rate of 500-1800 g of amino acids and / or oligopeptides per 1 ton of zeolite and when the zeolite is heated to a temperature of 35 to 90 ° FROM.

In a preferred embodiment, activated dehydrated zeolite is obtained by mechanical and thermal activation of natural zeolite, mechanical activation is carried out by crushing and sieving with separation of fractions of more than 0.1 mm, thermal activation is carried out in a rotary kiln with a gradual increase in the temperature of the zeolite along the length of the furnace from 150 ° C to 600 ° C and then with a decrease of 100-200 ° C with a total residence time in the oven from 40 to 120 minutes, and after thermal activation, the zeolite is intensively cooled to a temperature of no higher than 90 ° C.

Typically, zeolites are defined as three-dimensional crystalline structures having homogeneous pores (optionally only one cross section) of molecular size. Since aluminum and silicon can be replaced by boron, gallium or germanium, phosphorus, respectively, it is possible to prepare compositions of different compositions with the properties of zeolites and designated as zeolite-like structures.

The basis of the zeolite structure is the almost regular tetrahedron. Zeolites have a structure from the framework of tetrahedra ((Si, Al) O ₄ ), where negative charges are balanced, mainly Ca, Na, K. The framework contains large cavities and channels in which water molecules are present. Cations and water molecules are loosely bound to the framework and can be partially or completely replaced (removed) by ion exchange and dehydration, and reversibly, without destroying the zeolite framework. The zeolite devoid of water is a microporous crystalline “sponge”, the pore volume of which is up to 50% of the volume of the zeolite framework. Dehydrated zeolites can adsorb other substances instead of water: ammonium, alcohol, NO ₂ , H ₂ S, amino acids, etc.

Zeolite frames are similar to bee honeycombs and are formed from chains of silicon and aluminum anion exchangers. The molecular sieve properties of zeolites are determined by the effective diameter of the “windows”, which, in turn, depend on the geometric dimensions of the latter and the presence of exchange cations in them. To assess the possibility of a molecule of an adsorbed substance entering the adsorption cavity (both during adsorption of substances and during ion exchange), the diameter of the zeolite entrance windows (angstroms) is compared with the diameter of the adsorbed molecule itself (during adsorption) or with the diameter of various cations (during ion exchange) . Each of the zeolites is capable of sorbing molecules no larger than the size of their own "windows", i.e. This zeolite is not able to adsorb molecules whose size exceeds the pore diameter of this zeolite.

But in order to make the zeolite work in the right direction, it is necessary to modify it, which includes mechanical activation and thermal activation.

This process is aimed at obtaining a modified zeolite that can provide the formation of a synergistic compound with amino acids, in this process, the zeolite is activated as if by biostimulants - amino acids of low molecular weight, and amino acids as a result of zeolite modification, i.e. Its special preparations freely penetrate into the zeolite cavity and are held there until a certain time. This technology allows you to increase the shelf life of the fertilizer to unlimited time. When the fertilizer enters the soil, the processes of interaction of the zeolite as a carrier of amino acids with soil microorganisms begin. Having weak bonds with zeolite molecules, amino acids together with macro and microelements of zeolite form a complex structure and freely reach the root system.

An important property of modified zeolites is their porosity - the fraction of filling the volume of the material with pores. Total porosity or just porosity -

P total = (1-ro / ri) x100

ro is the average density of the material, g / cm3 (kg / m3);

ri is the true density of the material, g / cm3 (kg / m3).

Porosity is determined as a percentage.

The total porosity consists of open and closed.

Open porosity. According to the material, the volume of those pores that communicate with the external environment is called. Their volume can be measured by water saturation of the material. Open porosity is numerically equal to the water absorption of the material. Closed porosity Pzakr is calculated by the difference between the total and open porosity.

Zeolite modification is carried out to increase open porosity so that as many pores as possible are freed from impurities and zeolite water for the adoption of amino acids or any other enrichment agent. The porosity of the modified zeolite in the proposed group of inventions is from 45 to 75%.

The proposed method for producing organic fertilizers based on a modified zeolite enriched with amino acids consists of three main stages.

Stage 1. Preparation of zeolite for enrichment is a process of modification or activation. These are mechanical activation and thermal activation or dehydration, i.e. the process of firing and / or dehydration at the required temperatures, intensive cooling.

2 stage. Preparation of amino acids for the enrichment of zeolite is the process of dosing, mixing the main components, obtaining the desired concentration by dilution with water.

3 stage. Enrichment of zeolite with amino acids.

Next, the packaging of the fertilizer in big bags - polypropylene bags with a dense polyethylene liner or other containers in agreement with the consumer.

Mechanical and thermal activation of the zeolite can be carried out according to known technologies, while using this zeolite also achieves a technical result. The following is an example of a technology preferably used in the proposed method.

Stage 1. Mechanical activation

Zeolite intended for production and passed the input control enters the site of mechanical activation, where through the use of selective crushing and subsequent sieving, the zeolite is enriched by 5-20%. The effect of selective crushing is obtained due to the fact that clinoptilalite, biocalcite, have a significantly lower hardness than quartz and volcanic glass (impurities contained in the rock), and also differ in density.

Mechanical activation of natural zeolite allows you to change the mineralogical composition of the feedstock, namely: clean the natural zeolite from impurities and get a product with the maximum content of the active component — clinoptilalite and bentonite.

Raw materials - natural zeolite is crushed by crushing on a stone-separating rolls, followed by sieving on sieves with separation of the fraction up to 0.1 mm, preferably up to 0.7 mm. This is dust, which, as a rule, consists of organic impurities that do not correspond to the composition of the zeolite itself, and also includes fine silica sand, which impairs the properties of the final product.

After mechanical activation, the prepared feed goes to a subsequent thermal activation operation.

Thermal activation

With satisfactory results of the analysis of production control, after mechanical activation, the semifinished product of crushed and fractionated zeolite goes to a specialized thermal activation unit, where, at individual calculated temperature ranges, zeolite is dehydrated, zeolite water and gaseous impurities that the zeolite sorb under natural conditions, as well as organic impurities, are removed located in the breed. The stage of thermal activation of the semi-finished product takes place without breaking the crystal structure, the thermally activated zeolite retains its properties, allows you to keep vital trace elements in an unchanged amount.

Thermal activation of natural zeolite can significantly increase the adsorption capacity - a system of channels and cavities that permeates zeolite crystals. This system becomes more accessible for adsorbed molecules, dehydrated zeolite crystals most strongly exhibit molecular sieve effects, and also ensures the absence of pathogenic microflora in the final product, which once again confirms the safety of the product. For example, the specific surface of adsorption that has undergone thermal activation increases by more than 3 times compared with unactivated zeolite.

To ensure uniform fractional composition of the final product, obtaining the necessary properties, and a uniform enrichment process, the zeolite passes the granulation process on a plate granulator before the dehydration process. The size of the obtained granules can be adjusted in the range from 2 mm to 20 mm.

Preferably, 2-3 mm granules are obtained, which are conveyed by a conveyor belt to a rotary kiln. The amount of material, calculated by the productivity of the furnace, is 8-12 tons per hour.

During firing, the torch must be dimly lit, the direction of the torch axis must coincide with the axis of the furnace, the torch must not touch the lining of the furnace, nor the material, in order to avoid sintering of the material. The distance of the torch root to the edge of the furnace should be equal to one diameter of the shell, and the length of the torch is 0.1-0.2 of the length of the furnace.

The furnace is conditionally divided into 4 zones:

1 zone - drying zone. The length of the zone is 25-40% of the total length of the furnace. The temperature of the material in this area is up to 150 ° C,

Zone 2 - a zone of heating and chemical reactions. The length of the zone is 40-60% of the total length of the furnace. The temperature in the zone is from 150 to 800 ° C. In this zone, redox reactions occur,

Zone 3 - pre-cooling zone. The length of the zone is 5% of the total length of the furnace. The temperature should be below the firing temperature by 100-200 ° C.

The firing of the material occurs due to the contact of the latter with the shell of the furnace. The flame of the torch must not touch the material being burned. The material, moving through the kiln, must be in contact with the inner surface of the furnace, with the lining of the shell and, when rotated, rise to 2/3 of the inner diameter of the furnace, and then fall down. The firing temperature of the material consists of three components: the temperature of the gas medium, it must be 200 ° C higher than the temperature of the material itself, the temperature of the inner surface of the furnace, it must be 100 ° C higher than the temperature of the material, and the temperature of the material itself.

Upon exiting the kiln, the calcined material enters a layered refrigerator, where it is cooled and quenched, and the outer layer is formed. Intensive cooling of the dehydrated zeolite occurs until a product is obtained with a temperature not exceeding 90 ° C, preferably not higher than 30 ° C.

The firing temperature is controlled by the temperature of the exhaust gases.

Adjustment of the firing zones is carried out using the fan of the exhaust fan by opening and closing the gate, as well as adjusting the gas supply and the ratio of the air supplied to the combustion.

The firing time is 40-120 minutes, depending on the length of the furnace, its rotation speed. At the firing stage, it is necessary to carry out operational control: to monitor the temperature of the exhaust gases, to carry out visual control of the torch of the burner and the resulting product.

Dehydration of zeolite takes place at a temperature of 150-600 ° C. At this temperature, β-quartz transforms into α-quartz with an expansion coefficient of 1.082. At this temperature, all channels open, zeolite water and extraneous impurities that are saturated with natural zeolite are removed, and partial dealumination occurs - removal of free aluminum.

The moisture content of the modified zeolite should be in the range of 0.1-5%, no more.

Technological parameters of the obtained modified zeolite:

1. Appearance - granules of gray-yellow color

2. Bulk density - 650-700 kg / m ³

3. Fractional composition - 2-4 mm

4. The pH of the aqueous extract is 6.5-7

5. Water absorption - 35-65%

6. Porosity - 45-75

7. Moisture absorption - 3 liters of water per 1 kg of zeolite

8. Oil intensity - 61%

9. Water retention capacity - 96.13%

10. Thermal conductivity - 0.08-0.11 W / m * K

11. The compressive strength in the cylinder is 4.5-11.0 MPa

12. The total ion exchange (cation exchange) ability is 98.0 mEq / 100g

The porous microstructure of zeolites obtained by the proposed method determines the possibility of introducing useful components, in particular amino acids, into them and the creation of highly efficient, environmentally friendly and cost-effective fertilizers of a new generation on their basis.

Amino acids on the market obtained by any of the following processes: chemical synthesis, acid or enzymatic hydrolysis, or by fermentation using natural or GMO (genetically modified microorganisms), are peptides - chains of a large number of amino acid molecules, the size of which is larger than the pore size of the crystalline structure of zeolites, and they do not penetrate into these pores. The proposed invention uses free L-amino acids (AA) and / or oligopeptides with a small number of amino acid molecules in the chain, the size of which is equal to or less than 1 nm (10 Angstroms), have a low molecular weight and intense biological activity, they easily penetrate microscopic pores and actively participate in electron-ion processes inside zeolites.

Modified zeolite enriched with such amino acids has a high cation exchange coefficient, which is induced when a combination of zeolite + AA with soil is used, by the potential difference existing in the near zone near the root system of plants. Zeolite + AA, loaded with ions containing N, P, K, and trace elements, being an excellent transporter of these ions, down to the zone of microvilli of the root system, thus providing plant nutrition when it requires it, with maximum efficiency.

2 stage. Amino Acid Preparation

Water flows into cubic tanks. The water used is distilled, heated to 35-40 ° C. At the same time use 2 cubic tanks of 900 liters of water each.

Then measure and pour in a container of amino acids in a certain amount.

Using a small deep pump at low speed, all components are mixed to a homogeneous state. Stirring is slow to avoid the formation of foam. Next, the prepared mixture is fed through rubber pipelines to the supply tank of the mixing plant.

3 stage. The process of enrichment of a modified zeolite with amino acids. This process uses the BSU-60 production line manufactured by the Yaroslavl plant of JSC Stroytekhnika

The main unit of this production line is the SB-138B concrete mixer (1,500 l.) For the manufacture of mortars, concrete mixes, for mixing various bulk components and the preparation of multi-composite mixtures on the production lines of various enterprises. SB 138 concrete mixer refers to mixers with forced methods of mixing and cyclic action. The main working body of this installation are mixing blades. For loading components into the concrete mixer, a part of it is called skip and is a self-unloading lifting box. The feed hopper in which the modified zeolite is located is equipped with a heating system.

The enrichment process begins with weighing and feeding the zeolite modified with a self-loading skip hoist into the mixer. Dosing is carried out when loading modified zeolite based on 1 big-run, i.e. 1 m ³ , which corresponds to 650 kg. Next, an aqueous mixture of amino acids is fed into the mixer through the sprayer with constant stirring.

The whole process is automated, controlled from the operator through a computer according to a given program. The estimated time for supplying an aqueous solution of amino acids is 6 minutes This time was chosen after a series of mixes. For 650 kg of modified zeolite serves 52 liters of an aqueous solution of amino acids. Mixing is very good, almost all granules are wetted. The resulting mixture of modified zeolite with an aqueous solution of amino acids has a moisture content of 2.8-3.4%.

To improve the adsorption capacity of the zeolite before mixing it with amino acids, it is heated to a temperature of 35-45 ° C. In these designs for the enrichment of zeolite with nutrients - amino acids, atomizers are installed.

For the most efficient adsorption of nutrients into zeolite, the quantity and time of spraying of the supplied amino acid solution are important, and most importantly, the temperature of the mixture is heated. All parameters are listed in the technological regulations.

1. The amount of supplied solution of a mixture of amino acids -

80 liters per ton of zeolite modified.

2. Spray time - 6 minutes

3. The heating temperature of the zeolite material is from 35 to 45 ° C.

The volume of the amino acid solution and its concentration are calculated from the condition of 500-1800 g of amino acids per 1 ton of zeolite.

This technological unit allows spraying an aqueous solution of a mixture of amino acids, mixing them with a zeolite at a strictly specified temperature regime. The technological process allows to increase the efficiency of enrichment of zeolite modified with amino acids of low molecular weight and high activity.

The given values of the volume of the supplied solution of the mixture of amino acids are a particular example and may differ depending on the concentration of the solution, on the requirements for the final product, on the properties of the zeolite used, its ability to absorb water without destruction.

The proposed method was made fertilizers (Zeolite + AA) with an amino acid content per 1 ton of zeolite, are shown in table 1.

From table 9 it is seen that the proposed fertilizer contributes to a significant increase in barley yield.

The use of modified natural zeolite as a carrier of amino acids opens up great prospects. The unique properties of amino acids in combination with the active properties of zeolite, which in itself is quite widely used in agriculture, provide a really significant result.

No special measures are required during transportation and storage of fertilizer. It is recommended to store in a cool, dry, ventilated room, away from heat sources and direct sunlight, to avoid destructive effects on the product. Freezing to minus 20 ° C does not affect the activity of the substance.

The effect of the mechanism of action of zeolites + AA, when summing the properties of AA and zeolites with a high cation exchange coefficient, is as follows.

1. A significant increase in the yield of any crops and on all types of soils. This increase will be the higher, the worse the soil conditions.

2. Improvement in the medium and long term of soil fertility (especially in deserts), on which a new fertilizer is applied, which is the result of a combination of zeolites + AA.

3. Important savings for farmers when using this new biological fertilizer, its competitive price and nutritional efficiency by almost 100% compared to the expensive chemical fertilizers used so far and their maximum consumption by plants is only within 30-35%.

4. Increasing plant resistance to disease, pest attacks, drought and soil pathogens.

The fertilizer itself is a gray-yellow granule, the size of the fraction is 1-7 mm. The size of the fraction can be changed by agreement and the demand of the consumer. This granule size allows fertilizer application along with sowing of crops. For vegetables, the application is made in the fall before autumn treatment or in spring before pre-treatment.

The resulting organomineral fertilizer has high efficiency, allowing you to make smaller doses of fertilizer in the soil. It has a prolonged effect, the effect of the application lasts three years. Fertilizer fights against various plant diseases, disinfects the soil, absorbs radioactive elements and heavy metals, saturates the soil with moisture, and enables plants to develop well in the dry period.
