Description
Technical field
The invention belongs to polyaluminium chloride production technical field, it is related to a kind of solid polyaluminium chloride production dress of environment-protecting clean
Put.
Background technology
Polyaluminium chloride, is commonly called as water purification agent, also known as aluminium polychloride, abbreviation poly-aluminium, english name PAC；It is a kind of polyhydroxy
Base, multinuclear are complexed the cationic inorganic polymer flocculant of body, and solid product outward appearance is bronzing, yellow or white solid powder
End, its chemical molecular formula is [AL2(OH)nCL6-n]m(in formula, 1≤n≤5, m≤10), wherein m represents extent of polymerization, and n is represented
The neutral degree of PAC products, it is soluble in water, there is stronger bridge formation adsorptivity, with electrochemistry, cohesion, suction in hydrolytic process
The physico changes such as precipitation are echoed, [AL is ultimately generated2(OH)3(OH)3], so as to reach purification purpose.
The fundamental difference of polyaluminium chloride and traditional inorganic coagulant is that traditional inorganic coagulant is low molecule crystal salt, and
The structure of polyaluminium chloride is made up of the changeable polycarboxy complex compound of form, and flocculation sediment speed is fast, and applicable pH range is wide, right
Pipe-line equipment non-corrosiveness, purifying water effect substantially, can effectively branch water removal in the heavy metal such as chromaticness SS, COD, BOD and arsenic, mercury from
Son, the product is widely used in drinking water, industrial water and sewage treatment area.
Polyaluminium chloride is divided into form and is divided into two kinds：A. liquid polyaluminium chloride is undried form, is had without dilution, dress
The relatively cheap advantage of easy to use, price is unloaded, has the disadvantage that transport needs tank car, unit cost increase（Solid phase per ton
When in 2-3 tons of liquid）；B. solid polyaluminium chloride is dried form, has the advantages that convenient transportation, it is not necessary to tank car, shortcoming
It is that dilution is also needed to when using, increases working strength.
The raw material of production polyaluminium chloride mainly has two major classes：One class is aluminum-containing mineral, including bauxite（Gibbsite, one
Boehmite, diaspore）, clay, kaolin, alunite etc.；Another kind of is other aluminum-containing raw materials, including metallic aluminium, useless
Aluminium skimmings, grey aluminium, aluminium hydroxide, alchlor, gangue, flyash etc..The method of production polyaluminium chloride mainly has metal at present
Aluminium（Including aluminium ash, lead skim）Method, active aluminium hydroxide method, alundum (Al2O3)（Including bauxite, gangue etc.）Method, crystallization chlorination
Aluminium method etc..
1. metallic aluminium method：The raw material for synthesizing polyaluminium chloride using metallic aluminium method is mainly the leftover bits and pieces of aluminium processing, such as aluminium
Bits, aluminium ash and aluminium slag etc..Hydrochloric acid is added slowly with stirring according to a certain ratio by aluminium ash to be reacted, through curing polymerization, sedimentation
Liquid aluminium polychloride is made, then through dilute filtration, concentration is dried and is made.Acid system, alkaline process, neutralisation 3 can be divided into technique
Kind.Acid system, which is mainly, uses HCl, and product quality is difficult to control；Alkaline process producting process difficulty is higher, and equipment investment is larger and alkali charge
Greatly, pH controls take raw material, and cost is higher；Most is neutralisation, as long as controlling proportioning, is typically attained by national mark
It is accurate.
2. aluminium hydroxide method
Aluminium hydroxide powder purity is higher, and the levels of toxic substances such as polyaluminium chloride heavy metal of synthesis is low, and general use adds
The molten production technology of heat pressurization acid.This technics comparing is simple, but the basicity of the aluminium polychloride of production is relatively low, therefore typically
Added using aluminium hydroxide temperature-pressure acid is molten in calcium aluminate miberal powder and two procedures.
3. alundum (Al2O3) method
Raw material containing alundum (Al2O3) mainly has gibbsite, aluminium vanadine, kaolin, gangue etc..The production technology can
It is divided into two steps：The first step is to obtain crystal aluminum chloride, and second step is to obtain polyaluminium chloride by pyrolysismethod or neutralisation.
4. Alchlor process
Chlorination aluminium powder is used for Raw material processing polyaluminium chloride, this method application is the most universal.Can with crystal aluminum chloride in
170 DEG C of progress boiling pyrolysis, add water curing polymerization, then cured, dries and is made.
The solid polyaluminium chloride process units being completed at present, majority is that bauxite and calcium aluminate two-step method production liquid gather
Aluminium chloride, then by liquid polyaluminium chloride with spray drying or device that roller drying is solid polyaluminium chloride.Existing solid gathers

2）The roller drying system used, flow setting is not reasonable, causes energy consumption for drying cost too high, and by rolling
The transportation processing for the solid polyaluminium chloride that cylinder is dried is also more time-consuming；
3）The solid polyaluminium chloride being dried to obtain can be presented block hardened, if directly packaging is sold, can influence product product
Matter image；
4）For the processing and comprehensive utilization of filter residue, waste water and processing and comprehensive utilization containing sour waste gas and energy-conservation drop
The problems such as consumption, environment-protecting clean are produced is no to be dealt carefully with.
