Description
The present invention relates to a kind of acid decomposition green bean rock and produce potassium-nitrogen fertilizer, aluminium hydroxide, active silica, 4
Zeolite product and technology thereof.
Prior art: produce potash fertilizer with potassium bearing rock, all need high temperature sintering or fusion.Its method has shaft kiln legal system potash-lime fertilizer, blast furnace legal system silicon-magnesium potash fertilizer and fused(calcium magnesium phosphorus)potash fertilizer etc.Public technology:
1.1989 year June, " inorganic chemical technology is learned (three) chemical fertilizer " the 70th page " with potassium felspar sand system salt of wormwood and white fused cement " that chemical industry press publishes, be that various raw materials such as potassium felspar sand, Wingdale, rhombspar, bauxitic clay, fluorite and coal are crushed to certain particle size respectively, through screening, batching, send into blast furnace, at high temperature react, when temperature up to 1000 ℃～1300 ℃ the time, K
2O is displaced to begin to volatilize and overflows with furnace gas, meet carbonic acid gas and promptly generate salt of wormwood, the various coloring metal oxide compounds that contain in the furnace charge are reduced into metal by carbon and carbon monoxide, thereby separate with slag, this slag decolouring is white, can be used as the grog of white fused cement.
2. in October, 1978, the second geology group of former National Geology general bureau is at " Sichuan Province's potassium rich rock distribution overview, system potash fertilizer technology and farmland manure trial consolidated report " in the 71st page-98 pages a kind of silicon-magnesium potash fertilizer technology of producing is provided: with potassium rich rock (green bean rock), rhombspar, coal, pulverize and cooperation by a certain percentage, add in the blast furnace, allow furnace charge at high temperature react, when temperature during up to 1450～1500 ℃, melt becomes the melt of good fluidity, it is come out from blast furnace discharge port jet flow, under shrend, sharply cool off, become the black glass matter fertilizer of amorphism, drying, ball milling silicon-magnesium potash fertilizer.
The method that the objective of the invention is to avoid above-mentioned deficiency of the prior art and propose the sour low-temperature decomposition green bean rock of a kind of usefulness, its method technical process is simple, easy to use, free from environmental pollution, produce potassium-nitrogen fertilizer, aluminium hydroxide, active silica, 4 applicable to different scales
Products such as molecular sieve.
Solution of the present invention is: use the green bean rock of damouritization, with its pulverizing, add water and smash slurry, remove impurity, adding sulfuric acid furnishing liquid-solid ratio is 2: 1, and acidity is the slip of 30-40%, stirs, is heated to 100-120 ℃ in acid-resistant reactor, reacted 4-8 hour, filter fast while hot, clean insoluble slag with hot water, this slag is the active silica product of being produced.With filtrate evaporation concentration, cooling, stir, separate out potassium alum, again potassium alum is placed that ammonia soaks in the ammonia immersion trough, heated and stirred after ammonia soaks and reacts completely, is filtered simultaneously, cleans insoluble slag, oven dry promptly gets the aluminium hydroxide product of being produced; Filtrate evaporation concentration, crystallization make the potassium-nitrogen fertilizer product.
The present invention is the byproduct of used water micacization green bean rock system potassium-nitrogen fertilizer also: active silica and aluminium hydroxide produce 4
Molecular sieve, its solution are with active silica and aluminium hydroxide, press SiO

2. the present invention produces multiple product, no mine tailing, pollution-free, comprehensive utilization degree height with a kind of rock.
3. the active silica of producing with the present invention is different from other silica gel products, about pore volume is twice than general silica gel product.
4. produce K in the green bean rock by technical process of the present invention and technical requirements
2The O extraction yield is greater than 85%, and rock per ton can be produced:
(1) soluble potassium nitrogenous fertilizer [(K, NH

(3) 4
Molecular sieve 400-500Kg, whiteness 88-91%, the calcium ion-exchanged amount is greater than 290mgCaCO
3Exchange process of/g().
5. the product of producing with the present invention can further be produced efficient catalytic agent carrier, high-performance solid acetylene gas scavenging agent, white carbon black, light magnesium oxide and be used for the energy-conservation starting material etc. of synthetic microporous Calucium Silicate powder.
6. the present invention need not add any other auxiliary material when decomposing green bean rock.
7. technical process is simple, easy to operate, is applicable to the production of different scales.
Product of the present invention and technical process and technical requirements are provided by the following drawings and embodiment:
Fig. 1 is with green bean rock system active silica, aluminium hydroxide and potassium-nitrogen fertilizer technical process schematic block diagram
