Abstract
The present invention utilizes potassium ore powder and limestone powder (lime) or ground dolomite to make bulk behind the mixing by a certain percentage, be placed in annular kiln or tunnel furnace or the down-draft kiln, sintering at a certain temperature, sinter forms potash-lime fertilizer product or silicon-magnesium potash fertilizer product through pulverizing.This law has the potassium transformation efficiency height that can make in the potassium ore deposit, and the sintering process flow process is simple, is easy to red-tape operati, the less investment of founding the factory, characteristics such as cycle weak point.Have remarkable economic efficiency and social benefit.
Description
The invention belongs to the production method of inorganic chemical industry potash-lime fertilizer.It is that to contain the potassium silicate rocks with potassium felspar sand or other be raw material, is processed into a kind of novel method of potash-lime fertilizer or silicon-magnesium potash fertilizer with addition of Wingdale or rhombspar.
Potash fertilizer is one of plant three big nutritive factors.Plant is that balance absorbs pari passu to nitrogen, phosphorus, potassium, and the three promotes mutually, can not replace mutually.
The general severe potassium deficiency in China soil.China for a long time, nitrogen, phosphorus, potassium three big fertiliser production are in nonequilibrium state for a long time, the now existing suitable scale of nitrogenous fertilizer, phosphate fertilizer, and potash fertilizer does not satisfy needs far away.Its reason be China's soluble potassium ore resources except that the Northwest have a small amount of, other area almost is blank.The potassium ore resources that China exists is insoluble potassium felspar sand in a large number and contain the potassium silicate rock.China mainly contains two kinds of methods to the development and use of potassium felspar sand at present: a kind of is " potassium felspar sand system salt of wormwood coproduction white cement " method (seeing Appendix 1), and this method investment is big, simultaneously to potassium felspar sand ingredient requirement harshness; Another kind method is to produce potash-lime fertilizer.As for insoluble potassium felspar sand with contain the wet method development and use of potassium silicate rock, fail to form industrial production at present.
Traditional potash-lime fertilizer production method is that to contain the potassium silicate rock with potassium felspar sand or other be raw material, with addition of Wingdale and coal, and uniform mixing according to a certain percentage, abrasive dust, balling-up, high-temperature calcination in shaft kiln, pulverizing forms again.Its technical process sees background material II, III and IV for details.
The subject matter that traditional potash-lime fertilizer production method exists is: owing to be balling-up high-temperature calcination in shaft kiln, cause sintering temperature inhomogeneous easily, the sintering degree of sinter is inhomogeneous, causes the average conversion of the potassium in the potassium ore deposit not high; And sinter is easily tied bulk and serious sticking furnace wall in stove, be difficult for stirring and blanking, also can cause serious leakage raw material phenomenon.Like this, not only cause operational difficulty, labour intensity is big, and has a strong impact on output and quality.
The purpose of this invention is to provide a kind of easy to operately, make the high production potash-lime fertilizer of the average conversion of potassium or the novel method of silicon-magnesium potash fertilizer.
The present invention is achieved in that after calcining changes clamp dog in shaft kiln after traditional production potash-lime fertilizer or the balling-up in the silicon-magnesium potash fertilizer production technique and calcines in annular kiln (comprising vertical annular kiln and horizontal annular kiln) or tunnel furnace or down-draft kiln.
Process flow sheet of the present invention is seen the figure I.
Among the present invention, at first with potassium felspar sand or contain the potassium silicate rock and Wingdale (or rhombspar) separated pulverizing behind certain particle size, mix by a certain percentage again, its potassium ore: Wingdale=0.7-1.4, according to the sintering oven that adopts be equipped with a certain amount of coal again fine grinding become powder, clamp dog is put into annular kiln or tunnel furnace or down-draft kiln with the raw material piece of making again and is calcined then, calcining temperature is controlled in the 1150-1350 ℃ of scope, sintering time is 20-90 minute, and sintered clinker forms product through thick essence, grinding.
The present invention compares with original technology, has the following advantages:
1. the present invention can realize that the potassium in potassium ore deposit is converted into the high conversion of effective potassium of plant absorbing, and the condition test conversion ratio reaches as high as 98.2%, sees Table I. Compare with original technology, conversion ratio is significantly increased, and sees Table II.
2. sintering workshop section easy handling and management that potash-lime fertilizer or silicon-magnesium potash fertilizer are produced realize high-yield high-quality.
The present invention can also add a certain amount of one or more and contain the material or the mineral of elements such as manganese, zinc, boron, molybdenum, copper, rare earth in batching, obtain containing the potash-lime fertilizer or the silicon-magnesium potash fertilizer of corresponding kind trace element.
