Abstract
The process of preparing aluminum chloride polymer as water purifier with kaolin mineral includes drying kaolin mineral, calcinations at 600-750 deg.c, adding water to compound slurry, ageing, centrifugally separating, reacting in a reactor at 85-95 deg.c for 3 hr, centrifugally treating reaction product, concentrating filtrate to obtain liquid purifier or spray drying to obtain solid purifier, and treating filter residue through secondary eliminating impurity, centrifugal treating and drying to obtain white carbon black as excellent stuffing. The preparation process has aluminum utilization up to 95 %, and the water purifier has average grain size smaller than 40 nm, high water treating effect, high sludge depositing speed and low production cost.
Description
Technical field:
The present invention relates to the environment functional material field, is to utilize kaolin mineral to prepare the method for polyaluminium chloride water purification agent specifically.
Background technology:
Nonmetalliferous ores such as present domestic main employing coal gangue are the feedstock production polyaluminium chloride water purification agent, but the extraction yield of aluminium is low, the clean water treatment weak effect, and the flocculation time of response is long, and the sewage settling time reaches 3～4 hours.
Summary of the invention:
The objective of the invention is to overcome the weak point of prior art, and providing a kind of kaolin mineral that utilizes high yield to prepare the method for polyaluminium chloride water purification agent, this method is not only simple and effective, and the extraction yield height of aluminium, use this water purification agent obvious to the water treatment effect, sludge settling speed improves.
Technical scheme of the present invention is:
At first the kaolin raw ore is carried out drying treatment: drying temperature is 200 ℃, 2 hours time of drying;
Carry out calcination processing then: 600 ℃～750 ℃ of calcining temperatures, 1～2 hour after annealing time of calcining;
Join slurry again: take by weighing the kaolin raw ore and place in the reacting appliance for 200 kilograms, add 200 liters～240 liters tap water and be made into slurries;
Then use 36～50 gram Sodium hexametaphosphate 99s to carry out dispersion treatment, carry out the removing impurities by oxidation processing with the oxalic acid of 60 grams and the concentrated hydrochloric acid of 32 grams, reduce removal of impurities with the vat powders of 100 grams and handle, it is fully stirred 20 minutes after-filtration, add the 240 premium on currency pulp that stirs again;
And then ageing was handled 2 hours, after the centrifugation, added 200 premium on currency in filter residue, 215～218 kilograms of concentrated hydrochloric acids, and 85～95 ℃ were reacted 3 hours down in reaction vessel;
Next, centrifugal treating reactant again: filtrate giving concentrate after half liquid phase water purification agent or the spray-dried solid phase water purification agent that obtains; Filter residue is white carbon black then through the secondary removal of impurities after centrifugal treating and the drying.
The preparation method of polymerization oxidation aluminium water purifying agent of the present invention, its advantage and positively effect are embodied in:
The extraction rate reached to 95% of aluminium; The mean particle size of water purification agent is less than 40nm; Water purification agent is better than national standard after adjusting basicity; Use this water purification agent obvious to the water treatment effect, average consumption reduces 40%, and sludge settling speed improves more than 50%; Its byproduct white carbon black has fully been realized the comprehensive utilization of resource then as high quality filler; This preparation method is simple and effective, makes full use of the kaolin mineral of high yield, and production cost is low, and market outlook are wide.
