Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of rice husk Powdered Activated Carbon composite bentonite film-coated and slow release fertilizer
Preparation method.
Background technology
At present, countries in the world, especially developed country, all are being directed to developing efficient, free of contamination biomass energy profit
With technology, to reach protection mineral resources, national energy security being ensured, realizing carbon dioxide discharge-reduction, protection national economy can be held
The purpose of supervention exhibition.Biomass energy becomes the pith of following sustainable energy.Expect 2016, the global renewable sources of energy
Total energy consumption will there is 40% to come from biomass energy, mainly realized by the industrialized development of biomass power generation.Rice husk passes through
Pyrolysis obtains dry solid rice hull carbon, and carbon content is 50% or so, the essential nutrient element rich in plant growth, to water and fertilizer
Material has long-acting slow-release effect, and has improvement, repair to heavy metal pollution, the soil degenerated.
The content of the invention
The present invention provides a kind of preparation method of rice husk Powdered Activated Carbon composite bentonite film-coated and slow release fertilizer, prepared by the present invention
Film-coated and slow release fertilizer high adsorption, fertilizer strong adhesive force, reduce organic fertilizer generation agricultural pollution.
The present invention is achieved by the following technical solutions：
A kind of preparation method of rice husk Powdered Activated Carbon composite bentonite film-coated and slow release fertilizer, it is characterised in that comprise the following steps：
（1）The preparation of sticky powdered activated carbon
30-40 parts by weight rice husk is subjected to heating charing, is drenched by water-cooling-sprayer water spray, after being cooled to room temperature, with crushing
Machine crushes, and crosses 40-60 mesh sieves, after adding 2-5 parts by weight binder, after setting time and temperature to carry out extrusion forming, crush with
40-60 mesh is ground to, it is stand-by；
（2）Activated powder activated carbon and bentonite
By step（1）The powder of gained adds suitable after being mixed with 20-25 parts by weight of bentonite, 5-10 parts by weight Terramycin-type waste waters
After the water stirring and dissolving of amount, add the sulfuric acid of 40-50 parts by weight 30-60%, by microwave power be 190-225W, temperature be
145-165 DEG C of microwave treatment 30-45 minutes, it is stand-by after natural air drying；
（3）Compound with it is puffing
5-15 parts by weight of urea, 5-8 parts by weight of phosphoric acid magnesium are uniformly mixed, suitable quantity of water is sprayed, water content is reached 10%-20%
Pelletize afterwards by granulator, after carrying out humidification reunion after crushing, swelling granular is extruded as by bulking machine, is dried, is cold
But, it is stand-by；
（4）Sustained release parcel
By 5-8 parts by weight talcum powder and step（2）Gains are added in the rotating disk of fertiliser granulates kernel after mixing
Rotating granulation, while atomized water is sprayed onto step（3）Gained fertiliser granulates core surface, parcel arrives fertilizer under the action of atomized water
Expect particle core surface, obtain rice husk Powdered Activated Carbon composite bentonite film-coated and slow release fertilizer.
The heating charcoal is turned to carries out 100 DEG C/h of charing, heating in automatically controlled retort is made by temperature programming pattern
To 500 DEG C, when keeping 0.5-1.5 small.
The step（1）Drying be in vacuum drying chamber temperature be adjusted at 100-110 DEG C dry 5-7 it is small when.
For the extrusion forming to set pressing time 12-18 minute, it is 150-250 DEG C to set pressed temperature.
50-110 DEG C of the swelling temperature of the extruder, swelling granular is directly through 3-6 millimeters.
It is an advantage of the invention that：
The present invention drenches charred rice husk, after crushing drying, after adding binding agent, crushes, pulverizes after extrusion forming, afterwards
After bentonite, the dissolving of Terramycin-type waste water mixing and water adding, sulfuric acid is added, is air-dried by microwave treatment, urea and magnesium phosphate is mixed
The puffing granulation of progress is crushed after closing granulation, is mixed afterwards using air-dried gains with talcum powder and arrives swollen as coated fertilizer, parcel
Change fertiliser granulates surface both to obtain.Rice husk is carbonized, adds binding agent, binding agent enters molding micropore, can carry out
Increase the adsorptivity of activated carbon, increase the pore volume of activated carbon, improve the quality of activated carbon, afterwards with bentonite, terramycin medicine
For slag in acid solution, bentonite can destroy its structure, improve the reactivity of raw material, and Terramycin-type waste water will after microwave treatment
Substantial amounts of organic matter remains, while its nitrogenous total amount is to increase, the adsorbable more organic matters of rice hull active carbon, three
Synergistic effect, forms stable coated fertilizer, fertilizer it is for composite it is puffing after, granular fertilizer has numerous aperture, course of dissolution
In, moisture can rapidly penetrate into center along aperture, reach quick dissolving, prevent urea granules from directly being connect with seed after coating
Touch and influence germination, form slow controlled release, control mistake effect.Film-coated and slow release fertilizer high adsorption prepared by the present invention, fertilizer attachment
Power is strong, reduces the agricultural pollution of organic fertilizer generation.
