The present invention belongs to field of fertilizer manufacturing, and relating to a kind of is the multi-elements composite fertilizer that raw material is handled through spent acid with metallurgical slag, flyash, and this fertilizer is beneficial to plant absorbing and improves Soil structure, makes increasing crop yield.
Smelter will produce a large amount of solid waste such as slag, scum etc. aborning, also stay a large amount of spent acid behind the acid washing rolled steel, how these wastes are carried out the comprehensive regulation and utilization, the problem that becomes people already and paid close attention to, at present, utilize metallurgical slag to make slag fertilizer both at home and abroad, a lot of as fertilizer of crops with the material precedent of improving the soil, but all handle without spent acid.Fertilizer still belongs to silico-aluminate cement molecular structure and is difficult for by plant absorbing like this, and long-term application causes soil compaction, makes crop production reduction.
Its raw material of Japanese Patent JO116791 " lawn soil improvement material " is to be that main adding acid material and fertilizer are made with the converter slag, and acid material is nitric acid, hydrochloric acid, sulfuric acid, citric acid etc.; Fertilizer is nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, also has bone meal, fish meal etc., also will add a spot of polyethylene, methyl alcohol Mierocrystalline cellulose, carboxylic acid methyl alcohol Mierocrystalline cellulose etc. during fabrication.Be not difficult to find out that a series of cost of material that 1. problem that this material exists be to be added is higher, and on the make be not to use spent acid, so the material cost cost is very high, and complex process.2. be somebody's turn to do " improvement material " meta-alkalescence (as PH10.8), be unsuitable for northern meta-alkalescence soil, can cause soil compaction as long-term application.3. used waste residue is only emphasized converter slag; Use range also can only be used to improve lawn soil.
Chinese patent application number 911008012 " fertilizer synergistic agent and production technique thereof " are to be raw material with slag, rubbish, wild fiber and animal wool, skin, angle etc., through operations such as hydrolysis, neutralization, chelatings.Produce particulate state, fertilizer part of paste and various trace element, the fertilizer synergistic agent of rare earth element, though farm crop can be increased production, manufacture craft needs through the hydrolysis chelating comparatively complicated, cost is higher.
The objective of the invention is: at the fertile shortcoming and defect that exists of above-mentioned slag, provide a kind of metallurgical slag and flyash of utilizing to be raw material, handle and the multi-elements composite fertilizer made through spent acid, silico-calcium magnesium etc. becomes soluble salt in the fertilizer.Trace element discharges from interstitial solid solution, becomes available state nutrition, has both helped plant absorbing, improves Soil structure again, makes increasing crop yield.Good approach to deep processing in the comprehensive regulation of metallurgical waste also is provided simultaneously.
The object of the present invention is achieved like this: multi-elements composite fertilizer is to be that converter slag, open hearth slag, electric furnace slag, blast furnace slag and flyash are made into by weight percentage as raw material with metallurgical slag, handles and makes through spent acid.Above-mentioned several slag can be entirely with also selecting for use several and the flyash preparation, and be (weight percent) as joining: converter slag 35-45%, electric furnace slag 30-35%, open hearth slag 10-15%, flyash 15-20% then add sulfur waste acid or waste nitric acid or waste phosphoric acid and handle.Be abundant shelving three days to seven days that need that chemical reaction is carried out.Last multi-elements composite fertilizer granularity requirements is the 80-100 order.This fertilizer contains element and reaches kind more than 20, easily by plant absorbing, and improves Soil structure, makes farm crop reach the purpose of volume increase.
Slag fertilizer is through spent acid processing reaction principle: in metallurgical slag and the flyash, because of the spent acid effect:
Like this, silico-calcium magnesium becomes the salt of solubility, is easy to strengthen fertilizer efficiency into plant absorbing.Micro-Mn, Ti, Cu, Fe, Zn, S, B, V etc. also discharge from interstitial solid solution simultaneously.The reaction as:
Like this, trace element becomes the plant nutrition composition of available state, and, effect big, function singleness little for plant absorbing content promotes increasing crop yield.
Change within the specific limits about proportioning raw materials, be because of the Chemical Composition instability of metallurgical slag own, proportion scale changes with composition, and the spent acid consumption also will become according to the concentration of spent acid too, mainly to guarantee that improving fertilizer efficiency and reducing objectionable impurities is principle.
Concrete processing step is: slag is by the deironing of jaw crushing crusher machine, and belt is delivered to the vibration secondary crusher, and the secondary deironing reaches designated size through ball milling, enters feed bin, and flyash is through vibratory screening apparatus, enters feed bin respectively.According to the Chemical Composition of metallurgical slag, prepare burden by proportioning machine, carry out spent acid again and handle.Shelving three days to seven days is delivered to the drying machine drying.Carefully reach the 80-100 order through milling, packing is dispatched from the factory.
The advantage of multi-elements composite fertilizer of the present invention is: 1. the fertilizer nutritive ingredient is easily by plant absorbing, and the effect that improves Soil structure is arranged, and causes increasing crop yield.
2. range of application is wide, both has been applicable to northern alkaline soil, also is suitable for southern acid soil through changing the spent acid add-on.
3. to the various slags of the useless play of metallurgy thing and the comprehensive utilization of spent acid, carried out the approach of deep processing.
