Abstract
The present invention relates to the technical field of a method for producing active clay, which is designed for wastewater without acid and ordinary wastewater reducing. The method of the present invention is characterized in that the method orderly comprises the following steps that ore is dressed; raw soil is pulped, is purified and discharges sands and water; acid and water are added in, are activated for 10 to 30 minutes under an 80 to 100 DEG C temperature, and are simultaneously stirred at a high speed of 1000 r/min; absorption and filtration are carried out, a filtered solution is cycled into the pulping and purifying step, and slag is filtered into the next step; dryness and pulverization are carried out; a finished product is detected and packed. The present invention has the advantages of no pollution, low production cost and convenient operation, and is suitable for popularization and application.
Description
Technical field
The present invention relates to the method for producing active clay technical field.
Background technology
Account for certain status, widely used atlapulgite in national economy, not only production history is long, market position is firm, and still is in the stage of continuous rising.But the manufacture craft of present atlapulgite is as shown in Figure 1, and no matter domestic or external, do not make substantial progress decades, its expensive, poor benefit, and production process in serious acid pollution, restricted the development of this product and applied.Especially in the current environmental protection epoch, with great strength and vigour sour water is handled and discharging in the activated clay production process, forces the thin enterprise of part capital for want of to administer the enormous expenditure of sour water and haves no alternative but close, stop, change.Chinese patent also has the technology report of this respect.As the patent No. is that 90101333.1 activation of swelled ground, the patent No. are the production method of high-effect and activity clay by semi-hydrometallurgy of 90105982.X, its reaction adopts compressive reaction to improve the quality and the decolorizing ability of atlapulgite, does not still solve the sour water pollution problem preferably.And increase the production cost and the operation easier of reactor to a certain extent.
Summary of the invention
The object of the present invention is to provide the no acidic sewage discharge of a kind of Production Flow Chart, realize the method for producing active clay that CR production, production cost descend greatly.
Technical scheme of the present invention is to realize like this.This method for producing active clay is: 1, ore dressing; 2, original soil making beating, purification, and discharging grit and water, the pH value of water 〉=6; 3, add acid and water, activation is 10-30 minute under 80-100 ℃ of temperature, carries out high-speed stirring more than 1000 rev/mins simultaneously, and above-mentioned sour add-on is with mass percent concentration 98%H
2SO
4Counting needs activated bentonite 3-5% mass percent, and above-mentioned water is for needing activated bentonite quality 3-5 doubly; 4, suction strainer, filtrate cycle is to the purification step of pulling an oar; Filter residue is to next step; 5, drying is pulverized; 6, finished product detection, packing.
Above-mentioned acid is sulfuric acid, hydrochloric acid.
Its comprehensive production cost of the carclazyte that this production technique provides descends greatly, and the rate of profit of this product is brought up to more than 30% by about 15% of routine, and promptly the industrial profit rate is enhanced about more than once.See the production cost comparison sheet.
Production cost relatively
One ton of atlapulgite finished product of every production prime cost contrast table
General: common atlapulgite.
High: high-efficient activated clay.
| Sulfuric acid (kg) | Coal (kg) | Electricity (degree) | Water (degree) | Man-hour | Waste water control | |
| Traditional technology | 150-250kg (general) (height) | About average 300 Kg | About average 100 degree | About average 100 degree | In traditional technology is " 1 " | Need |
| Xin Xin skilled worker's art skill | 40 60kg (general) (height) | General: substantially need not or a small amount of high: about double centner | General: high about 20 degree: about 50 degree | About 20 degree | Novel process needs about 0.5 approximately | Do not need |
And do not have sour water discharging in the Production Flow Chart, and be its PH of common waste water 〉=6, realized CR production, not only can administer expense, and solve the environmental issue that makes the headache of enterprise for enterprise saves a large number of blowdown.
Its technology theory is according to Huffman ion sequence, hydrogen ion comes the foremost, even with under the isoconcentration, hydrogen ion also can get off calcium ion-exchanged, but consider various secondary reactions and other factor, we only need two to the hydrogen ion that is four times in calcium ion, and it just can get off calcium ion-exchanged, in the actually operating, after to the flow measurement of need activatory wilkinite cationic exchange, quantitatively add hydrogen ion amount, be equipped with the appropriate reaction condition again, just can realize the activatory purpose times over calcium ion.This by the sulfuric acid calculating of 98% content, in theory only needs the 1-3% of original soil amount just passable times over the hydrogen ion amount of calcium ion.
