Abstract

The invention provides a kind of method of utilizing vertical cyclone furnace to produce directly potassium silicate fertilizer, this method is directly mix a certain amount of Wingdale (or serpentine) and phosphate-containing ore in bunker coal after, burn in the vertical cyclone furnace of slag tap, the high pressure steam that obtains can be used for generating or uses as other energy.The slag tap that furnace bottom is discharged is exactly a potassium silicate fertilizer.Potassium silicate fertilizer is a kind of good fertilizer that is used for paddy rice, reed, vegetables, fruit tree, and it can prevent disease and pest, and strong stem stalk is resistant to lodging, and can make fruit, fresh-keeping of vegetables.

Description

Utilize the method for vertical cyclone furnace to produce directly potassium silicate fertilizer
The technical field of the invention is the agrochemicals fertilizer.
Potassium silicate fertilizer is used for paddy rice, reed, it is remarkable to dredge on the crops such as dish, fruit tree fertilizer efficiency, especially for paddy rice, reed, can make the crop root prosperity, increases and divides an evil, strong cane, but lodging-prevention, full seed.To paddy rice, every mu is applied fertilizer 30~50 kilograms, can increase production 10~20%; Be used for vegetables, fruit, can in leaf and pericarp, form silicified cell, prevent water evaporates, increase sugar part, effects such as fruit, Vegetable Preservation, disease and insect resistance.Use this fertilizer the crop sickness rate is obviously descended, being used for other crop also has remarkable fertilizer efficiency.
At home and abroad some unit once carried out the experimental study of calcium silicate fertilizer, did not burn small-scale test and the industrial test that potassium-bearing mineral is made siliceous fertilizer but also utilize vertical cyclone furnace to mix.
Tokyo Electric Power succeeded in developing with flyash and makes siliceous fertilizer in 1972.Hokkaido, Japan commercial exploitation test institute and waste engineering institute began usefulness flyash, salt of wormwood, potassium hydroxide, magnesium hydroxide in 1980, and coal dust is raw material, produced potassium silicate fertilizer in 900 ℃ of fluidized-beds.This method also needs equipment such as tablets press, drying oven, Reaktionsofen except that with the above-mentioned raw materials, sets up and produces 20000 tons of potassium silicate fertilizer factories per year, needs 2,000,000 yuan of investments.
The purpose of this invention is to provide a kind of method of utilizing vertical cyclone furnace to produce directly potassium silicate fertilizer, can simplify technology, reduce cost, reduce the investment of founding the factory.
The present invention is that method realizes below adopting.
In coal combustion, mix a certain amount of Wingdale or serpentine, and phosphate-containing ore (preferentially selecting potassium felspar sand, rosy clouds Fang Yan, alunite etc. for use) carries out the silicon conversion reaction in the vertical cyclone furnace of slag tap, and the slag tap of emitting is exactly a potassium silicate fertilizer.
The present invention has following advantage:
1, the present invention has saved fluidized-bed, Reaktionsofen, fluidized bed roasting operation with comparing with the method for flyash system potassium silicate fertilizer, has saved facility investment.
2, with in the potassium silicate fertilizer of explained hereafter of the present invention, have 73% to be transformed by original cyclone furnace Water Quenching Slag, effectively utilized the heat content of liquid slag.Therefore, method of the present invention is than existing method energy-conservation 73%.
3, combustiblematerials drops to 2% from 8% in the flying dust that produces in boiler roasting fine coal process, makes boiler thermal output improve 1%.
4, mix the burning phosphate-containing ore and pounce on slag rate raising 10%, promptly siliceous fertilizer output improves 10%.
Embodiment 1
After Wingdale (or serpentine), phosphate-containing ore, coal dust mixed by the ratio of components of table 1 and putting into ball mill and pulverize, send in the upright cyclone furnace and carry out roasting.Operational condition is: carry out insoluble silicon in the cyclone furnace of 1300~1600 ℃ of temperature of normal pressure, calcium changes into the reaction of soluble silicon, calcium and the Chinese holly of elements such as potassium, magnesium dissolves reaction.Material is 10~30 minutes at residing time in furnace, and most optimal retention time is 15~25 minutes, produces high pressure steam in the boiler water tube, and the liquid slag that furnace bottom is discharged gets potassium silicate fertilizer after shrend.Fertilizer composition example is in table 2.

Utilize vertical cyclone furnace to produce the normal operation that potassium silicate fertilizer does not influence boiler, steam parameter is stable, and the thermal technology is all right, and boiler thermal output still reaches original design level, and the boiler operatiopn data are summarized in table 3.
