Abstract

A process for preparing silicon fertilizer features that the silicon-contained waste dregs generated in preparing procedure of aluminium sulfate is used as raw material which reacts on alkali to result in said silicon fertilizer. Its advantages are simple process and low cost.

Description

The technology of preparing silicon fertilizer from waste dregs of aluminium sulfate
The present invention relates to a kind of technology of preparing silicon fertilizer from waste dregs of aluminium sulfate.
The factory that produces at present Tai-Ace S 150 mostly abandons aluminum sulfate dregs, uses it for deep processing washing composition etc. after having only indivedual factories therefrom to carry the dispense liquid water glass.In fact, mostly contain 30~70% the siO of having an appointment in these siliceous waste residues 2, but all be difficult to directly be absorbed by plant.
The objective of the invention is to provide a kind of technology of preparing silicon fertilizer from waste dregs of aluminium sulfate, this production technique is not only simple, and production cost is low, and helps utilization of waste material.
First kind of process program of the present invention is: 1) adopting the siliceous waste residue after producing the Tai-Ace S 150 operation is raw material; 2) adding solid base mixes thoroughly; 3) reaction made siliceous fertilizer more than five minutes under 20-110 Celsius ℃.
Second kind of process program of the present invention is: 1) adopting the siliceous waste residue after producing the Tai-Ace S 150 operation is raw material; 2) above-mentioned siliceous waste residue being dropped into concentration is to stir evenly in the alkali lye more than 1%; 3) reacted 5 minutes to 5 hours down in 20~110 ℃ Celsius.For the intensified response effect, after can flooding, the siliceous waste residue in the input alkali lye reacts again.After the reaction, liquid can be leached, as washing composition and binding agent, the waste residue of gained is siliceous fertilizer; Also can be with the solution of gained and waste residue together as siliceous fertilizer.
Alkali described in above-mentioned first kind and the second kind of process program can be potassium hydroxide or sodium hydroxide.Described waste residue is that all contain the waste residue after aluminium silicon composition raw material makes Tai-Ace S 150, as aluminium vanadine waste residue, bauxite waste residue; The kaolin waste residue, or the alunite waste residue etc.
Can make various composite fertilizers if in the siliceous fertilizer that above-mentioned technology makes, add various infrastructure elements and the trace elements that help crop growth.Show that through province's academy of agricultural sciences's agricultural experiment the composite fertilizer that application technology of the present invention makes contrasts with similar not siliceous composite fertilizer, can increase production to reach 6-20%.This fertilizer can be widely used in the plantation of plants such as paddy rice, wheat, sugarcane, vegetables Lay, fruit tree, watermelon, grape.
The present invention reacts owing to add solid-state or liquid alkali in siliceous aluminum sulfate dregs, so can be converted into the siO that helps crop absorption to the silicon-dioxide major part in the aluminum sulfate dregs 2Thereby it is simple to make technology, the siliceous fertilizer that cost is low.
Below in conjunction with embodiment the present invention is specifically described
Embodiments of the invention one are:
Containing siO 2Be to add 8 kilograms of solid sodium hydroxides in " aluminum sulfate dregs " 100 kilograms more than 20%, at room temperature place after stirring to make in three days and contain effective siO 2Be 100 kilograms of about 16% siliceous fertilizers.Also can add 20 kilograms of Repone K in this siliceous fertilizer again gets 120 kg and contains K about 10% 2O and contain about 13% effective siO 2Solid state si potash fertilizer.
Embodiments of the invention two are:
Containing siO 2Be to add 15 kilograms of solid potassium hydroxide in " aluminum sulfate dregs " 100 kilograms more than 20%, at room temperature stir the companion evenly, place to make in two days and contain effective siO 2Be about 16% and contain K 2O is about 11% Si-K fertilizer 105 kg.Also can in this Si-K fertilizer, mix to contain P again 2O 5Be 80 kilograms in about 13% phosphate fertilizer, make 185 kilograms and contain siO 2About 9%, K 2O about 6% and P 2O 3About about 5% solid state si potassium phosphate fertilizer.
Embodiments of the invention three are:
Containing siO 2Be that to add concentration in " aluminum sulfate dregs " 100 kilograms more than 20% be 100 kilograms of 5% above liquid caustic sodas, constantly stir that the maintenance temperature of reaction makes 60 kilograms after 5-10 minute and contains SiO at 92-98 ℃ 2Be about 12% filtrate (for deep processing he with) and 75 kilograms contain effective SiO 2About about 13% solid siliceous fertilizer.
Embodiments of the invention four are:
Containing SiO 2Be that to add concentration in " aluminum sulfate dregs " 100 kilograms more than 20% be liquid caustic soda 120 kg 5% or more, constantly stirring, temperature of reaction is controlled at 50-90 ℃ must contain effective sio after two hours 2About about 16% siliceous fertilizer 120 kg also can add silicon, phosphorus, potassium, the solid composite fertilizer that base fertilizers such as phosphate fertilizer, potash fertilizer, nitrogenous fertilizer are made total nutrient about 30% in this siliceous fertilizer.(still can add a spot of trace element again) according to all kinds of farm crop needs.
More than each routine fertilizer both can make powdery and also can be made into granular.
