Description
Technical field
The invention belongs to field of fertilizer production, be specifically related to a kind ofly produce the novel process of sal enixum and the application in S-based compound fertilizer thereof.
Background technology
" country's 12 planning outlines " are all classified as the series of problems such as grain security, Ecological Civilization Construction, energy-saving and emission-reduction in planning, and fertilizer plays a part very important as " grain in grain " in the enforcement of this planning.Within 2011, No.1 Central File more pays attention to water saving, in water saving, improves in utilization rate of fertilizer, is applicable to drip irrigation and spray irrigation fertilizer and more accords with the demands of the market.Market Water soluble fertilizer mostly is physics blending method secondary processing, relative waste of manpower, material resources, and mixes uneven, and fertilizer efficiency is unstable.
The development of China's fertilizer and application history, be main phase from farm manure to use inorganic fertilizer, because farm manure source of pollution are many, traffic capacity is large, operationally wastes time and energy and effect is not obvious especially; And inorganic fertilizer composition is single, utilization ratio is lower, and often causes soil compaction and adjoint soil erosion polluted source, influence ecological environment.The fertilizer of agricultural use mainly contains (NH in the early time

2cO belongs to acyl ammonium fertilizer, contained nitrogen need after the urine enzyme decomposition and inversion of urea bacterium secretion be ammonium nitrogen, can be absorbed by plants, its utilization ratio is generally 30 ~ 40%, and it has, and fertilizer efficiency utilization ratio is low, volatile, contaminate environment, precipitation, burning seedling burn the drawback such as leaf and soil compaction.In recent years, occurred some Chemical Mixed Fertilizers and biological organic fertilizer, which raises grain yield, and the fertilizer efficiency time length improves, and reduces the destructive force of environment; Such as Chinese patent CN102503650 discloses a kind of amino acid chelate fertilizer, this chelating fertilizer is by adding chelating amino acid and trace element, improve fertilizer efficiency, but it is higher to there is raw materials cost in this technology, need to add various trace elements and amino acid, general enterprises cannot bear high cost, and causing can not large-scale industrial production.
The sal enixum intermediate raw material that domestic production S-based compound fertilizer is used, mainly adopts the red Repone K of import and the vitriol oil to react in reactive tank.When building S-based compound fertilizer device before domestic 10 years, due to little to the demand of red potassium, import red potassium price and domestic white potassium difference less, and the advantage of red potassium is the low (W (H of moisture content
20) 0.2% one 0.5%), in pelletized form, K
2the high ((K of 0 content
20) 60% ~ 61%), steady quality, when reactive tank and sulfuric acid reaction, state is comparatively stable, and sal enixum overflow is also more stable, easy to operate, so domestic S-based compound fertilizer device uses the red potassium of import to produce S-based compound fertilizer always.Along with S-based compound fertilizer device gets more and more, the red potassium demand of import is increased fast.According to related statistical data, the red potassium of import per ton and domestic white potassium price difference are approximately about 100 yuan.In order to reduce costs, be necessary to produce S-based compound fertilizer with domestic white potassio for the red potassium of import.But use in domestic Repone K and there is following problem: 1,57% (K
20 content) Repone K moisture content is high, and in use slip surface flotation one deck material needs to be dissolved in water sometimes, and nitration mixture water content increases, cause compound fertilizer oven dry load large on the one hand, water content increases on the other hand, and hydrogenchloride is soluble in material oar, CI in material oar
-content improves, CI in product
-content also can correspondingly improve.Domestic Repone K moisture content is high, and viscosity is large, and conveying difficulty is large, and feed intake instability, causes compound fertilizer final product quality unstable.Use procedure overflow is unstable, causes finished product potassium content to fluctuate.2,60% (K
20 content) in use reactive tank emits vapour, nitration mixture density fluctuation is large, overflow is unstable, boiling explosion phenomenon etc.
Summary of the invention
The present invention be directed to the defect of prior art fertilizer production technology, a kind of novel process of producing sal enixum of proposition, this technique employs state's words spoken by an actor from offstage potassium, and cost reduces greatly, and chloride ion content is low.Present invention also offers a kind of S-based compound fertilizer and preparation technology thereof, this composite fertilizer effectively utilizes agricultural waste material, and employs microbial fermentation technology, and holding water and fixing nitrogen effect is better, fertilizer efficiency is more lasting, rate of fertilizer reduces greatly, energy-conserving and environment-protective simultaneously, achieve and turn waste into wealth.
