The present invention is a kind of preparation method and application thereof of liquid palymeric aluminium sulfate, and its chemical general formula is
Description
The present invention relates to a kind of preparation method and application thereof of liquid palymeric aluminium sulfate.
Waste water, sewage and drink water purifying are handled, and use the widest maximum treatment agents to should be Tai-Ace S 150, but the Tai-Ace S 150 poor performance at low temperatures, and often have the higher remaining aluminum compound of concentration in the drinking water quality after handling, therefore progressively substituted by other treatment agents.Polymerize aluminum chloride has been compared its many advantages with Tai-Ace S 150, but polymerize aluminum chloride is for the many water quality of inorganics and algae, and perhaps the water treatment effect of slant acidity is just not very good.Application number is the alkali formula chloro Tai-Ace S 150 of " 89100474 ", this product be used for condensing and flocculate material of aqeous suspension, particularly handle as drinking water quality, the remaining aluminium of the water after handling few especially, but it adopts aluminum oxide or aluminium hydroxide is raw material, production cost is higher, but because the raw material sources problem of product has limited production.
The present invention is directed to the deficiency of prior art, the aluminiferous bauxite mine that utilizes nature to be easy to get comes the synthetic fluid polyaluminium sulfate for raw material.
The present invention fully reacts with aluminiferous bauxite mine and sulphuric acid soln, make aluminum sulfate aqueous solution through solid-liquid separation, then above-mentioned aluminum sulfate aqueous solution and alkaline earth metal compound or ammonia are under agitation carried out polyreaction, material after the polymerization is fully removed the Tai-Ace S 150 of impurity and alkaline-earth metal through solid-liquid separation, promptly obtains liquid palymeric aluminium sulfate.
With aluminiferous bauxite mine prepare aluminum sulfate aqueous solution with following proportioning raw materials for well: aluminiferous bauxite mine sulfuric acid water=1～12 09～13 15～2(weight ratio), bauxite mine aluminum content (Al
2O
3) with about 40% calculating, sulfuric acid is with 98% cubage.The sulfuric acid here can be 98% industrial sulphuric acid, also can be 60～70% dilute sulphuric acid.
Aluminiferous bauxite mine comprises useless alum slurry, bauxitic clay, aluminium ore powder, aluminium hydroxide and coal gangue etc.
For bauxite mine and sulphuric acid soln are fully reacted with the preparation alum liquor, logical steam reaches under 2.5Kg～3Kg its system pressure when reaction, reacts discharging after 6 hours.Cohesion is lumpd for fear of feed concentration is too high, can add the water of proper amt during blowing, carries out solid-liquid separation after treating to cool off slightly, and its filtrate is required alum liquor.General water is regulated its concentration and is contained Al at 5.5%(
2O
3Amount is by weight) more than.
Above-mentioned aluminum sulfate aqueous solution is put into the container that has agitator, under agitation constantly drip alkaline earth metal compound or ammoniacal liquor.And measure pH value at any time, if basicity is controlled at 35～70%, then PH be controlled at 〉=3.5 o'clock, stop to add alkaline earth metal compound, continue reaction about 30 minutes, i.e. discharging is removed impurity and insoluble vitriol through solid-liquid separation, filtrate is liquid palymeric aluminium sulfate.
This alkaline earth metal compound comprises lime carbonate, Calcium hydrogen carbonate, calcium hydroxide, calcium oxide and their mixture, also can use ammoniacal liquor and Tai-Ace S 150 polymerization.
When Tai-Ace S 150 and alkaline earth metal compound or ammonia polyreaction, stirring velocity is controlled to be about 60 rev/mins to well.
The chemical general formula that reacts the liquid palymeric aluminium sulfate of gained through above-mentioned two steps is:
Al
n(OH)
mSO
4(3n-m)/2 or (Al(OH)
mSO
4(3-m)/2)
n, n=8～72; M=12～18; The monomer molecule amount is 124.7～133.8, and m/3n is the basicity of liquid palymeric aluminium sulfate in the formula, and its value is 35～70%, and best values is 40～60%, can select different basicity for use according to the purposes of product.This product is a kind of dark-brown clear solution.
With aluminiferous bauxite mine is the liquid palymeric aluminium sulfate of feedstock production, not only can handle as drink water purifying, industry is useless, the flocculation agent of sewage disposal, also can be used as the sizing agent of paper industry, the reodorant of petroleum chemical industry etc.
Technology of the present invention is simple, and raw material sources are wide, low cost of manufacture.The product that produces with the present invention is a kind of good inorganic polymer flocculant, have applied widely, the particle of wadding a quilt with cotton is big with fixed attention, characteristics such as settling velocity is fast, and when low temperature, it is stable that its effect still keeps.
Accompanying drawing is a process flow sheet of the present invention.
The present invention is described in further detail below in conjunction with embodiment.
