(2) by batching compatibilizing ingredient composting material.
Japan J 61170525 blast furnace dirt 50kg, CaSO
42H
2O 7kg, slag 500kg mix cooling and are fertilizer.
The poor phosphoretic steel slag of East Germany DL261145 mud, converter accretion and rhombspar, the Ca that is mixed in proportion, Mg, P fertilizer.
(3) by melting operation residue adjustment composting material
Japan's J56127717 low silicon iron take off S, P adds CaCl
2And CaF
2Promptly stoping phosphoric acid salt to become can not dissolved salt, does not hinder the fusing point that takes off S, P and reduce slag again, makes as early as possible and separates from molten iron, and soluble phosphate is fabulous fertilizer.
Britain GB1179246 converter steelmaking, by improving oxygen top blown, P content makes basic slag fertilizer in the increase slag.
(4) by chemical treatment composting material.
The hydrous oxide of vanadium leaches vanadic salts by carbonate in the West Germany DE3006264 slag, has both got V
2O
2Solution obtains phosphate fertilizer again.
Japan's J01168791 lawn soil modifying agent is to add fertilizer 1-30% in converter slag, add acid and acid material 0.5-5%, add mineral vegetable mould 1-30%, the rotary drum of packing into add again acid polyethylene, first hydroxylated cellulose mix 3 minutes promptly packing dispatch from the factory.
Summary of the invention
The present invention aims to provide a kind of wide to soil suitability, can be used as the raw material of compound fertilizer, and production technique is simple, cost is low, do not produce the silicon-calcium-magnesium-sulfur fertilizer and the preparation technology thereof of the solid-liquid gas three wastes.
The technical solution used in the present invention is:
A kind of silicon-calcium-magnesium-sulfur fertilizer, it is a raw material with slag, blast furnace slag, iron-tion slag, ferroalloy slag, non-ferrous metal slag and flyash, handles and makes through the soda acid chemical reaction, form is Powdered or particulate state, when it is Powdered, and granularity≤0.15mm, during its particulate state, granularity is 0.5mm-1mm, by weight percentage, contain in its chemical ingredients: at least 9% Si, at least 14% Ca, at least 1.5% Mg, at least 0.1% S, at least 1.5% Fe, at least 0.1% Mn; Its Ph value is 5.0～8.0.

Chemical process is handled: table 3 has provided the acidizer allocation ratio, and the acidizer configuration proportion all satisfies: sulfuric acid 40～60%, nitric acid 20～30%, phosphatase 11 0～15%, hydrochloric acid 10～15%.The half-finished Ph value of its silicon-calcium-magnesium-sulfur fertilizer all is controlled in 5.0～8.0 scopes.Chemical process is handled and is undertaken by following operation:
Configuration acidizer → container (meter is heavy) → helical stir mixer (adding acid base catalysator) → chemical treatment container, carry out chemical treatment in 24-72 hour, the soda acid chemical reaction temperature is controlled between 25～60 ℃, pending abundant reaction (decomposition, hydrolysis, complex phase) back → drying machine → silicon-calcium-magnesium-sulfur fertilizer (work in-process).
The batching granulation is undertaken by following operation:
Powdered finished product: silicon-calcium-magnesium-sulfur fertilizer (work in-process) → runner milling, be milled to≤the 0.15mm granularity → through after the assay was approved → metering packing.
The particulate state finished product: silicon-calcium-magnesium-sulfur fertilizer (work in-process) → runner milling, 0.15mm granularity → tablets press (0.5-1.0mm), through after the assay was approved → metering packing.
Select different regions, different crops to test respectively in Hebei by 1#, 2#, 3#, 4# silicon-calcium-magnesium-sulfur fertilizer that above-mentioned steps is made, test-results sees Table 4, and test effect is remarkable.
