Method of production of a complex fertilizer

FIELD: production of a complex fertilizer.

SUBSTANCE: the invention is pertinent to production of a complex fertilizer and the method of production of the complex fertilizer provides, that the ground phosphate admix with a waste pickling solution in a mass ratio of 1:1, then they add perlite of the faction of 1.6-2 mm in amount of 5 % relative to the mass of the mix and the mix is fed into a screw-conveyor drier, where formation and drying of granules at the temperature of 150-180°C is exercised. The produced fertilizer has the insect-fungicidal and meliorating properties at simultaneous fertilizer cost reduction and utilization of the pickling solutions.

EFFECT: the invention ensures production of the fertilizer with insect-fungicidal and meliorating properties at simultaneous reduction fertilizer cost and utilization of the pickling solutions.

 

The invention relates to agriculture, namely, the feeding of vegetable and grain crops.

The method of obtaining phosphoric fertilizers, enriched with trace elements of phosphate from waste metal-working industries, in particular waste etching solutions and electrolyte galvanic production,

The invention consists in that the phosphorite flour is processed by etching with a solution of the following composition (in percent):

H2SO4- 14,0; FeSO4- 22,8; Zn - 0,02; Ni - 0,02; Cu - 0,03.

Closest to the present invention are A.S. No. 333155, No. 1488290 and No. 2034819 class C 05 D 9/02 and C 05 D 3/04 (USSR).

The purpose of the invention is improving the quality of fertilizers by giving them injectionmolding properties and improve the environmental situation.

This objective is achieved in that the phosphorite not decomposed with sulfuric acid and the spent etching solution containing iron, zinc, Nickel, copper, manganese and other

There is a method of processing waste etching solutions to obtain compound fertilizers with microelements, including mixing etching solutions with shredded basic metallurgical slag. The disadvantage of this method is the output of mineral fertilizers with low content of available phosphorus, which is one of the main pit is positive elements for plants and one of the criteria of their quality.

The most common method of disposal pickling solutions up to the present time is to neutralize them with plaister, and then neutralized wastewater is transported to the landfill of industrial waste.

The neutralization process occurs by the following reactions:

FeSO4+Ca(OH)2=CaSO4+Fe(OH)2

H2SO4+Ca(OH)2=CaSO4+2H2O

However, the method of neutralization has some significant drawbacks.

Requires large capital expenditures on construction and maintenance stations neutralization. As a result of neutralization produce large quantities of precipitate of iron hydroxide and calcium sulphate. In addition, a significant drawback of neutralization is irretrievable loss of valuable components contained in the etching solution.

The objective of the invention is to increase crop yields through the introduction of complex fertilizers and the disposal of waste metal-working industries.

Complex fertilizers in addition to the primary nutrients - phosphorus containing trace elements, giving insectofungicide properties, and add fertilizer perlite increases reclamation quality fertilizer.

The essence of the method lies in the fact that phosphorite flour is mixed with the spent tra the strong solution mass ratio of 1:1, then added perlite f - 1.6 to 2 mm in an amount of 5% by weight of the mixture. The mixture is then fed into a screw dryer, where education and drying the granules at a temperature of 150-180°C.

For the decomposition of phosphate use the waste pickle liquor factory “Red October”, the following composition (g/l):

H2SO4- 110,0-120,0; FeSO4- 50-60; Ni is 0.5 - 0.8; C is 0.5 to 1.0; Zn - 5-8.

The chemical composition of phosphorites Kamyshin deposits (in percent):

P2O5- 14-18; Cao - 30-35; R2O5- 10-12; N2O - 1-1,5; F - 1,5-2; SiO2- 30-40.

Perlite is produced from perlite sand by heating to 900° C, with the result that he becomes porous with a bulk weight of 0.1 g/cm cubic

Phosphorus is mixed with the spent pickling solution in a 1:1 ratio, and then add perlite. The mixture is stirred for 20-30 minutes, resulting in a homogeneous mass. The reaction of the interaction between phosphate and the OTP Autoterminal, the temperature rises to 60-70° C.

The resulting mass is fed to the granulation and drying, and then on packaging.

The resulting fertilizer has the following composition (in percent):

P2O5- 10-10,5; Sa - 20-25; F - 1-1,5; SiO2- 25-30; Fe - 6-7.

The elements are in the fertilizer in the form of sulfates and oxides, 58,0% plant-digestible form.

Add fertilizer perlite gives Mel aeroasia properties, the product is well granulated, number retur small. Such fertilizers should be used in as ameliorants with pittelli effect on saline soils.

The use of waste etching solutions instead of sulfuric acid decomposition of phosphate to reduce the cost of fertilizers, simplifying the technology of their production and to stop the landfills, waste production, which are the pickling solutions.

Method of production of complex fertilizers from waste solutions pickling of ferrous metals, including drying of the finished product, characterized in that the phosphorite flour mixed with waste etching solutions containing trace elements at mass ratio of T:W=1:1, then mixed with perlite fraction of 1.6-2 mm in an amount of 5% by weight of the mixture, and drying the reaction mass is carried out at 150-180°C.
