Abstract
The production method of CFS remodeling sodium bentonite belongs to the deep process technology of bentonite material.Mainly be applicable to natural calcium-base bentonite is become sodium bentonite with the artificial modification.
Core of the present invention is that the calcium bentonite ore deposit with natural saturated humidity adds light ash under the condition of pressure and shearing deformation, carries out exchange reaction fast and generates sodium bentonite.Make the calcium-base bentonite ore deposit of China's abundant adopt this law to generate the sodium bentonite product, remedied deficiency with multipurpose and in great shortage natural sodium bentonite of high-quality.This law is suitable for factory's serialization produces, and cost is low, is better than the production method that adopts at present both at home and abroad.
Description
The invention belongs to the deep process technology of bentonite material.Mainly be applicable to natural calcium-base bentonite is become sodium bentonite with the artificial modification.
The fifties begins to do with bentonite the binding agent of drilling mud and casting mold sand, after be used as the iron ore pellets material, be used as the raw material of A type and X type zeolite molecular sieve recently again, also can be used for developing high-silicon type catalytic cracking agent, water-impervious type cement concrete and clay-organic complex etc.And sodium bentonite has better physical and chemical performance and bigger industrial application value is arranged than calcium-base bentonite.Bentonite all has utmost point purposes widely at home and abroad in a word.
By retrieval, document related to the present invention is:
1, " bentonite ore domestic production technical merit and development trend "
2, United States Patent (USP) U.S.P 3865240
Find out from above-mentioned document: produce at present both at home and abroad the method for remodeling sodium bentonite with calcium-base bentonite, do not break through all that people grasp already at Na
2CO
3Carry out the method for ion-exchange reactions in the solution.The shortcoming of this method is: 1, increased oven dry, disintegrating process and the equipment of raw ore, 2, because the cationic inherent characteristic of smectite mineral interlayer interchangeability of bentonite composition makes Na
+To Ca
++Exchange velocity slowly (experimental results show that needs could exchange more than 16 hours to finish), be difficult to be put to industrial production, 3, because this traditional exchange procedure is to carry out in liquid-phase system, the dispersion suspension multiplication of reaction back product, cause solid, liquid separating treatment technical difficulty big, need to consume a large amount of energy, increase a large amount of filter plants, simultaneously the spent lye contaminated environment, 4, cost height is about four times of calcium-base bentonite producing cost.
At present, the external natural raw ore of calcium base bentonite of handlebar is banked up ageing more than ten days with after light ash mixes, dries, abrasive dust generation sodium bentonite product then.Its shortcoming is: 1, be unwell to the factory serialization and produce, 2, unstable product quality, 3, to consume the light ash amount big, is generally 4～6%.
The object of the present invention is to provide a kind of factory's production continuously, steady quality, sodium bentonite production technology that cost is low of being suitable for.Make in the natural montmorillonite of China's abundant with Ca
++-montmorillonite is the main calcium-base bentonite ore deposit of forming, and adopts this method to generate remodeling with Na
+-montmorillonite is the main sodium bentonite product of forming, and replaces the in great shortage natural sodium bentonite of high-quality that serve many purposes, present.
Formation of the present invention:
1, ore dressing: with the natural raw ore of calcium base bentonite of saturated aqueous,
It is 2, just broken,
3, add light ash,
4, mix,
5, pressure and shearing deformation is carried out exchange reaction in special purpose reactor, generates the modification sodium bentonite.Become bentonite in powder by former dry process again, i.e. finished product.
Process chart as shown in Figure 1.
Annotate: be content of the present invention in the frame of broken lines.
Process conditions are:
1, natural bentonite saturated humidity (water content 30～50%), raw ore should contain montmorillonite greater than 65%, with Ca++Ion is main, burning into sand stone not,
2, first broken rear granularity should be less than 1 centimetre.
3, soda ash meets the GB210-63 standard, and through pulverizing its particle less than 20 mesh sieves,
4, adopt the double helix mixer to carry out mix and blend,
5, microcomputer control: carry out the dynamic measuring batching with single board computer and control and on request technological process is controlled,
6, double helix reactor: adopt double helix propulsion auger device, pressurize during work, pressure is 50～150Kg/Cm2, with 100Kg/Cm2For good, but simultaneously detrusion is accelerated exchange reaction speed.
Below introduce principle of the present invention:
Montmorillonite mineral characteristic in the bentonite, have easy and external cation and polar molecule generation exchange reaction under certain condition, and exchangeable cation is to be hydrated form to exist in montmorillonite-aqueous systems, like this, when an amount of light ash being added and having in the bentonite of an amount of saturated humidity, because Na
+The aquation of ion can character, causes the Ca that adsorbs between to original layer in the variation of aqueous medium between montmorillonite layer
++Ion generation exchange reaction.Cationic exchange interaction also is to meet law of conservation of mass, and the cation concn of replacement increases, and generally can cause by the chance of that cation exchange to increase and the exchange capacity increase.The switch type letter is shown:
The invertibity of cationic exchange of montmorillonite mineral interlayer aquation and absorption except by the stoichiometric reaction reason, also is subjected to the restriction of thermodynamic property, is penetrating the time that some particle surface enters arrangement thereby influence ion hydration.For this reason,, make the solid bentonite ore under certain pressure and detrusion condition by a kind of special reaction unit, can be at very fast generation of moment Na
+To Ca
++The exchange reaction effect, be retrofit into sodium bentonite.Its exchange reaction formula is:
The inventor has carried out nearly 100 groups experiment to more domestic bigger natural montmorillonite, adopts Xinyang spinal cord natural calcium bentonite, smectite content 80.78%, and impurity christobalite 15% is pressed this technological process at 100Kg/Cm
2Retrofit under the condition, all obtained high-quality sodium bentonite product.Now lift several examples as above page or leaf of embodiments of the invention tabulation (1).
Advantage of the present invention is as follows:
1, Na
+To Ca
++Exchange reaction speed fast, whole technical process was less than 2 minutes (and ion-exchange reactions was finished in moment).
2, owing to short production cycle, can realize factory's serialization production, can form an automatic assembly line.
3, used bentonite is natural raw ore, and the soda ash that batching adds is powdery, is dry production, and no spent lye is handled problems, and free from dust exists again, so the non-environmental-pollution problem.
4, production equipment is uncomplicated, small investment, and the sodium bentonite production line that yearly productive capacity is 2.5 ten thousand tons is no more than 150,000 yuan.
5, owing to reinforced and process with microcomputer control, the automaticity height, full production line only needs operating personnel's per tour 7 people, and alkali consumption is 1/2 of an old technology alkali consumption, and the while energy consumption also reduces, and causes the whole production cost to reduce about 40%.
6, produce not only automaticity height, and constant product quality with microcomputer control.
7, because light ash (Na
2CO
3Powder) be in sealing device, by microcomputer control feeding, thus no dust, and raw ore is natural saturated humidity bentonite ore, also do not have dust.
8, very high economic worth is arranged: 50～60 yuan/ton of costs, 60 dollars/ton of American selling prices.
