Description
Technical field
The utility model belongs to poly aluminium chloride production technical field, is specifically related to a kind of production equipment producing liquid poly aluminium chloride.
Background technology
Poly aluminium chloride, is commonly called as water purification agent, has another name called polymerize aluminum chloride, is called for short poly-aluminium, english name PAC; It is the cationic inorganic polymer flocculant of a kind of poly-hydroxy, multinuclear complexing body, and solid phase prod outward appearance is sorrel, yellow or white solid powder, and its chemical molecular formula is [AL

ncL
6-n]
m(in formula, 1≤n≤5, m≤10), wherein m represents extent of polymerization, and n represents the neutral degree of PAC product, soluble in water, there is stronger bridge formation adsorptivity, with physico changes such as electrochemistry, cohesion, absorption and precipitations in hydrolytic process, final generation [AL

3], thus reach purification object.
The fundamental difference of poly aluminium chloride and conventional inorganic coagulating agent is that conventional inorganic coagulating agent is low molecule crystal salt, and the structure of poly aluminium chloride is made up of the polycarboxy complex compound that form is changeable, flocculation sediment speed is fast, be suitable for pH value wide ranges, to pipe-line equipment non-corrosiveness, purifying water effect is obvious, and effectively can prop up dewater middle chromaticness SS, COD, BOD and the heavy metal ion such as arsenic, mercury, this product is widely used in tap water, process water and sewage treatment area.
Poly aluminium chloride is divided into form to be divided into two kinds: a. liquid poly aluminium chloride to be undried form, have and need not dilute, load and unload easy to use, that price is relatively cheap advantage, shortcoming is traffic requirements tank car, and unit cost increases (solid per ton is equivalent to 2-3 ton liquid); B. solid poly aluminium chloride is dried form, has the advantage of convenient transportation, does not need tank car, also needs dilution when shortcoming is and uses, and increases working strength.
The raw material producing poly aluminium chloride mainly contains two large classes: a class is aluminum-containing mineral, comprises bauxite (gibbsite, boehmite, diaspore), clay, kaolin, alunite etc.; Another kind of is other aluminum-containing raw material, comprises metallic aluminium, aluminium scrap bits, grey aluminium, aluminium hydroxide, aluminum chloride, coal gangue, flyash etc.The method of current production poly aluminium chloride mainly contains metallic aluminium (comprising aluminium ash, lead skim) method, active aluminium hydroxide method, aluminium sesquioxide (comprising bauxitic clay, coal gangue etc.) method, crystal aluminum chloride method etc.
1. metallic aluminium method: adopt the raw material of metallic aluminium method synthesis poly aluminium chloride to be mainly the tankage of aluminium processing, as aluminium bits, aluminium ash and aluminium slag etc.Under agitation slowly add hydrochloric acid according to a certain ratio by aluminium ash to react, obtain liquid aluminium polychloride through slaking polymerization, sedimentation, then through dilute filtration, concentrated, dry obtained.Technique can be divided into acid system, alkaline process, neutralisation 3 kinds.Acid system mainly uses HCl, and quality product is wayward; Alkaline process producting process difficulty is higher, and facility investment is comparatively large and alkali charge is large, and pH controls to take raw material, and cost is higher; Maximum be neutralisation, as long as control proportioning well, generally can be up to state standards.
2. aluminium hydroxide method
The levels of toxic substances such as aluminium hydrate powder purity is higher, the poly aluminium chloride heavy metal of synthesis are low, the general production technique adopting heating and pressurizing acid-soluble.This technics comparing is simple, but the basicity of the polymerize aluminum chloride produced is lower, and therefore generally employing aluminium hydroxide temperature-pressure is acid-soluble adds in calcium aluminate breeze and two procedures.
3. aluminium sesquioxide method
Raw material containing aluminium sesquioxide mainly contains gibbsite, aluminium vanadine, kaolin, coal gangue etc.This production technique can be divided into two steps: the first step obtains crystal aluminum chloride, and second step obtains poly aluminium chloride by pyrolysis method or neutralisation.
4. aluminium chloride process
Adopt chlorination aluminium powder to be Raw material processing poly aluminium chloride, this method application is the most general.Available crystal aluminum chloride carries out boiling pyrolysis in 170 DEG C, adds water cure polymerization, then through solidification, dry obtained.
Liquid poly aluminium chloride production equipment built at present, majority is the device that bauxitic clay and calcium aluminate two-step approach produce liquid poly aluminium chloride, it is in the acid-soluble reaction of the first step and second step polyreaction, capital produces a large amount of insolubles and is difficult to be separated with reaction solution, causes insolubles severe overweight in final poly aluminium chloride product.Therefore, must improve existing liquid poly aluminium chloride production equipment, effectively to control and to reduce the insolubles content in reaction solution, improve the seed output and quality of liquid poly aluminium chloride.
Pressure filter is a kind ofly utilize filtration medium to apply certain pressure to object and make liquid dialysis a kind of mechanical means out.Filter material is injected filter chamber by the pressure of fresh feed pump by pressure filter, filter material enters filter plate by the feed port of thrust plate end face, make filter material be distributed to all filter chambers by filter plate centre hole again, after the filtration medium of filter chamber makes solid-liquid separation, reach the object of filtration.Existing pressure filter generally only adopts adjustment feed pressure to be used as the pressure source of press filtration, although can service requirements be met, but, along with the development of filtering equipment, the filtration area of pressure filter continues to increase, and the quantity of filter plate is also on the increase, the length of pressure filter is constantly lengthened, if only adopt the feed pressure strengthening fresh feed pump to provide press filtration pressure, then filter cake can be caused can not press filtration to complete for a long time, reduce production efficiency.
In addition, because the length of pressure filter constantly lengthens, after press filtration completes, cannot guarantee that all filter chambers all can be opened, cause filter residue not get rid of smoothly, after needing to adopt manual operation to be opened by the filter chamber do not opened one by one, remove filter residue again, not only waste of manpower, and reduce production efficiency.
