Description
Technical field
The present invention relates to intend thin water washing field, particularly a kind of method and device that reduces the pseudo-boehmite leaching requirement.
Background technology
[0002] pseudo-boehmite is a kind of chemical aluminum oxide, is powdery solid, and pore volume is about 0.3～1.0ml/g, about specific surface 200～300m2/g; Because its high-ratio surface, large pore volume, surfactivity is big, so often be used as catalyzer or support of the catalyst, is widely used at petroleum chemical industry.
But because its product porous, the product of producing washing difficulty is big, and water is difficult to the incidental sodium washes clean of solid, but does not have other effective washing methods, can only wash with water now in the production, and the bath water amount is very big.Along with the development of chemical aluminum oxide, the output of pseudo-boehmite is increasing, and the consequent is that the bath water amount is also very big.The water loss of different sorts pseudo-boehmite is greatly about 20～100 tons, and the washing mother liquor contains the sodium ion of lower concentration, and it is too high to recycle energy consumption.Therefore, reducing the washing process leaching requirement is the primary problem that pseudo-boehmite is produced.
Summary of the invention
One of purpose of the present invention provides a kind of method and device that reduces the pseudo-boehmite leaching requirement.
According to an aspect of the present invention, provide a kind of method that reduces the pseudo-boehmite leaching requirement, comprising:
Aging slurries to pipe-line transportation carry out ultrasonication; Or
The washing lotion of stirring in the rinse bath is carried out ultrasonication.
According to another aspect of the present invention, provide a kind of device that reduces the pseudo-boehmite leaching requirement, comprising: ultrasonic processor, described processor for ultrasonic wave are arranged at pipeline or the rinse bath of carrying aging slurries.
Method and device according to reduction pseudo-boehmite leaching requirement provided by the invention can reduce the bath water amount, improve the Na ion concentration of washing mother liquor.
Description of drawings
Fig. 1 is a kind of process flow sheet that reduces the method for pseudo-boehmite leaching requirement that the embodiment of the invention proposes.
Embodiment
As shown in Figure 1, a kind of method that reduces the pseudo-boehmite leaching requirement that the embodiment of the invention provides comprises:
Step 10, the aging liquid of pseudo-boehmite is sent into pressure filter carry out press filtration.
After step 20, the press filtration, realize liquid-solid separation, filter cake is sent into rinse bath.
Step 30, agitator treating groove stir filter cake and to wash, stir wash in, carry out ultrasonication with the processor for ultrasonic wave that is arranged on rinse bath to stirring washing lotion.This moment 85 ℃ of wash temperatures, leaching requirement: amount of solid=20:1 stirs 30 rev/mins of the stirring velocitys of washing trough, ultrasonic intensity may be selected to be 300W ~ 5000W, be 5 ~ 60 minutes action time.Wherein, preferably the ultrasonic intensity of 300W was handled 30 minutes stirring washing lotion.
Repeat above-mentioned steps 10 to twice of step 40.
Step 50, gained filter cake after the press filtration is carried out quiet washing again, qualified up to index (sodium content); The quiet pseudo-boehmite product of washing the back gained is carried out drying operation again.
The embodiment of the invention also provides a kind of method that reduces the pseudo-boehmite leaching requirement, comprising:
Step 60, the aging liquid of pseudo-boehmite is sent into pressure filter carry out press filtration.
After step 70, the press filtration, realize liquid-solid separation, filter cake is sent into rinse bath.
Step 80, agitator treating groove stir filter cake and to wash.This moment, wash temperature was 85 ℃, leaching requirement: amount of solid=20:1.
Step 90, will stir slurries after washing with pipe-line transportation to pressure filter.At pipeline ultrasonic processor is set.With ultrasonic processor the slurries of pipe-line transportation are carried out ultrasonication, ultrasonic intensity may be selected to be 300W ~ 5000W, and be 5 ~ 60 minutes action time.Wherein, preferably the ultrasonic intensity of 1000W is handled the slurries of pipe-line transportation, and the treatment time is 10 minutes.
Wherein ultrasound intensity is 1000W, and be 10 minutes action time.
Step 100, the washing lotion of stirring of pipe-line transportation is carried out press filtration with pressure filter.
Repeat above-mentioned steps 60 to twice of step 100.
Step 200, gained filter cake after the press filtration is carried out quiet washing again, qualified up to index (sodium content); The quiet pseudo-boehmite product of washing the back gained is carried out drying operation again.
The action of ultrasonic waves effect is embodied in two aspects:
(1), since ultrasonic wave be high frequency oscillation, with respect to common agitator treating, the washing intensity increased a lot.From microcosmic, in the agitator treating process, the attached liquid in solid particulate internal holes and the fluid exchange of particle surface are limited in one's ability.Liquid in the thing, particularly particle centre portions hole does not contact substantially with the liquid of particle surface, so the agitator treating weak effect.For supersound washing, because action of ultrasonic waves is arranged, the liquid of microscopic particles inside has the effect of a concussion, and this concussion provides power with regard to giving granule interior liquid with mixing of surface liquid, and the water of relatively small amount just can reach the effect same with agitator treating.
(2), ultrasonic wave has refining effect to solid particulate.Ultrasonic wave is smashed the flocculated particle of pseudo-boehmite, becomes the dispersive small-particle, thereby becomes particle surface and adhere to sodium being wrapped in sodium ion in intermolecular, the hole, under same wash conditions, easier sodium is washed off.
Can reduce 5～30% of pseudo-boehmite wash water consumption by this method, and every indexs such as the pore volume of pseudo-boehmite, specific surface are not affected all.
Carried out the laboratory simultaneous test under the situation of the same washing water yield, the part laboratory results is as shown in table 1:
Table 1
Table 1 shows, contrasts under the same wash conditions, and after the adding ultrasonic wave, it is low that the sodium oxide in the cleaning product does not more add ultrasonic wave (just normal agitator treating) in washing process.This explanation ultrasonic wave is apparent in view for the effect of washing deoxidation sodium.
When strengthening washing effect, do not find that ultrasonic wave can bring detrimentally affect to other index of product, part test result's product analysis is as shown in table 2:
Table 2
As can be seen from Table 2, the product performance index difference that two kinds of mode of washing obtain is little, and its difference is (for example, in 5%) within analytical error.This explanation ultrasonic wave can not brought qualitative influence to product.
The embodiment of the invention also proposes a kind of device that reduces the pseudo-boehmite leaching requirement, comprising: ultrasonic processor, processor for ultrasonic wave are arranged at pipeline or the rinse bath of carrying aging slurries.
The method and the device of the reduction pseudo-boehmite leaching requirement that the embodiment of the invention proposes, not only can reduce and (for example intend thin washing water consumption, hold index such as index does not have under the affected situation at the pore volume of pseudo-boehmite, specific surface, glue, reduce pseudo-boehmite wash water consumption 5～30%), reduce production costs, but also the Na ion concentration of washing mother liquor is improved, the cost of recycling sodium reduces.
The foregoing description is a preferred implementation of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
