Description
Technical field:
The invention belongs to a kind of preparation method of vegetable fertilizer, particularly relate to a kind of method for preparing kalium-nitrogen-sulphur-magnesium-ferrotitanium silicon foliage fertilizer and calcium-sulphur silicon fertilizer with titanium-containing blast furnace slag.
Background technology:
Because the discharging of titanium-containing blast furnace slag has caused the loss of a large amount of titanium resources, also environment is polluted simultaneously, therefore the utilization to it has become the focus that people pay close attention to.Titanium-containing blast furnace slag can not be directly used in Cement Production, has therefore limited its use.Climbing steel research institute and cooperate with the Zhongnan Polytechnic Univ, is raw material with the steel climbing high slag, developed and produced the novel process that artificial rutile and sulfuric acid process are produced titanium dioxide, has produced grade greater than 98% rutile TiO
2And other titanium dioxide of multiple level such as welding rod level, ceramic grade, pigment-level, and its residue can be used for producing cement.At the end of the eighties, finished with titanium-containing blast furnace slag and produced TiCl
4Experimental study.In recent years, report about the titanium-containing blast furnace slag Treatment of Coal-gas Washing Water Using appears again.But all there are some drawbacks in approach of these comprehensive utilization slags, and perhaps treatment capacity is limited, and the titanium resource utilization ratio is low, perhaps complex manufacturing, and have secondary pollution.How eliminating titanium-containing blast furnace slag and can utilize titanium resource in large quantities to pollution, the while of environment, is present urgent problem.
Titanium improves intensity of photosynthesis in growing process, increase plant chlorophyll content and food value of leaf dry weight, promotes the synthetic of plant pigments and carbohydrate; Improve the activity of plurality of enzymes such as catalase, peroxidase, nitrogenase, nitrate reductase and fructose-1; Increase the root nodule number, improve fabaceous nitrogen fixing capacity; Improve plant to nitrogen, phosphorus, potassium and trace element the ability that absorbs, quicken nutritive substance and transport to seed as zinc, manganese, iron, copper, boron, molybdenum; Involved in plant metabolism, delay plant senescence phase; Improve plant drought resistance; Promote growth and development of plants, strengthen the physiologically active of plant, farm crop are had precocity, premature labor and production-increasing function.
The formation of silicon involved in plant cell walls, the physical strength and the steadiness of raising plant tissue, the moisture loss of reduction horny layer of epidermis improves plant drought, lodging tolerance and resistance against diseases; Promote plant-growth and photosynthesis, promote the absorption of plant, improve crop yield and quality nutritive elements such as nitrogen, phosphorus, potassium.
The external titanium fertilizer of using in early days mainly contains titanium sulfate ammonium and TiCl
3Deng, how not the special-purpose formulation of commodity of typing.The titanium fertilizer of the present production and sales of China mainly contains 891 titanium preparations and NK-P nutrient for plants etc., and this type of titanium hypertrophy is many by poisonous and hazardous TiCl
4Pure product are feedstock production, and cost height and nutritive element kind are few.In addition, the foliage fertilizer of the present production and sales of China is scarcely siliceous.The present invention prepares kalium-nitrogen-sulphur-magnesium-ferrotitanium silicon foliage fertilizer and calcium-sulphur silicon fertilizer with titanium-containing blast furnace slag, has avoided above-mentioned shortcoming.

The detection of fertilizer: the kalium-nitrogen-sulphur-magnesium-ferrotitanium silicon foliage fertilizer to embodiment carries out Atomic Emission Spectral Analysis, the result shows: the characteristic spectral line of potassium, nitrogen, sulphur, magnesium, titanium, iron, silicon has appearred in the spectrum of foliage fertilizer sample, illustrate potassium in the foliage fertilizer, nitrogen, sulphur, magnesium, titanium, iron, silicon all with water-soluble cpds as effective constituent; Foliage fertilizer is carried out the mensuration and the calculating of magnesium, titanium, iron level, and the result shows: magnesium accounts for the full magnesium of titanium-containing blast furnace slag more than 90% in the foliage fertilizer, and titanium accounts for the full titanium of titanium-containing blast furnace slag more than 80%, and iron accounts for the full iron of titanium-containing blast furnace slag more than 75%.
Calcium-sulphur silicon fertilizer to embodiment carries out CaO, SO
3, SiO
2Determination on content, the result shows: CaO content 20%-27% in the calcium-sulphur silicon fertilizer, SO
3Content 31%-36%, SiO
2Content 15%-24%; Calcium-sulphur silicon fertilizer to embodiment carries out X-ray diffraction analysis, the result shows: the characteristic peak that has occurred calcium sulfate and Calucium Silicate powder in the spectrogram of sample, wherein calcium sulfate is the microsolubility material, Calucium Silicate powder is the solubility in citric acid material, illustrate that sulphur exists with the form of microsolubility material calcium sulfate, silicon mainly exists with the form of solubility in citric acid material Calucium Silicate powder.The solubility in citric acid material generally is to be insoluble in water, is the chemical substance of the secretions from plant roots of representative but dissolve in 2% citric acid.For the instantly-soluble material, microsolubility material and solubility in citric acid substance dissolves speed are slower, therefore are difficult for losing with current, can effectively be absorbed by crop for a long time.
Research conclusion: containing titanium dioxide 14%-30% is to handle at this blast furnace slag, and titaniferous is too high, low excessively can not to be brought technique effect or not have practical significance, influences the application of titanium resource in other field on the contrary.With titanium-containing blast furnace slag in air atmosphere, be warming up to 1350-1500 ℃ and be incubated 5-45min after drop in the water and carry out shrend, be in order to improve the reactive behavior of slag, and then in the process of heating and melting, be easy to take place frit reaction; Shrend, dried slag are obtained the powder of diameter 60-160 micron through grinding, are in order to play the improved melt effect, the too big DeGrain of diameter, and diameter is too for a short time to be there is no need, and increases cost on the contrary.With slag powder and 3-20 times of ammonium sulfate by weight, monoammonium sulfate, ammonium pyrosulfate, ammonium persulphate mixes, be in order to play the improved melt effect, generate more soluble substance, make potassium in the foliage fertilizer, nitrogen, sulphur, magnesium, titanium, iron, silicon all with water-soluble cpds as effective constituent, make that magnesium accounts for the full magnesium of titanium-containing blast furnace slag more than 90% in the foliage fertilizer, titanium accounts for the full titanium of titanium-containing blast furnace slag more than 80%, iron accounts for the full iron of titanium-containing blast furnace slag more than 75%, and this promotes physiological action such as synthesizing of photosynthesis and carbohydrate to play important effect in growing process to the performance titanium; Multiple is inoperative very little, and multiple there is no need too greatly, increases cost on the contrary.In filtrate, add 0.4-8 doubly to xitix by weight, citric acid, the EDTA of slag powder, and with saleratus, salt of wormwood, potassium hydroxide regulator solution pH to 5.0-8.0, be in order to make titanium and xitix, citric acid, EDTA chelating, improve the stability of foliage fertilizer, and then help the absorption of plant more nutritive element; Multiple is inoperative very little, and multiple there is no need too greatly, wastes raw material on the contrary; The too high or too low absorption that all is unfavorable for plant to nutritive element of pH.This method technology is simple, and resulting kalium-nitrogen-sulphur-magnesium-ferrotitanium silicon foliage fertilizer and calcium-sulphur silicon fertilizer are the multielement compound fertilizer, and the fertilizer stable in properties is easy to storage, and validity period is more than 2 years.
