Description
Technical field
The utility model belongs to poly aluminium chloride production technical field, relates to one solid poly aluminium chloride production system safely and efficiently.
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
2(OH)
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, in hydrolytic process, follow the physicsization such as electrochemistry, cohesion, absorption and precipitation to change, the final [AL that generates
2(OH)
3(OH)
3], thereby reach purification object.
The fundamental difference of poly aluminium chloride and traditional inorganic coagulant is that traditional inorganic coagulant is low molecular crystal salt, and the structure of poly aluminium chloride is made up of the changeable polynary carboxyl complex compound of form, flocculation sediment speed is fast, be suitable for pH value wide ranges, to pipe-line equipment non-corrosiveness, purifying water effect is obvious, can effectively prop up the heavy metal ion such as middle chromaticness SS, COD, BOD and arsenic, mercury that dewater, and this product is widely used in tap water, process water and sewage treatment area.
Poly aluminium chloride is divided into form and is divided into two kinds: a. liquid poly aluminium chloride is undried form, have and need not dilute, load and unload advantage easy to use, price is relatively cheap, 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, while not needing tank car, shortcoming to be use, also needs dilution, increases working strength.
The raw material of 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 producing at present 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.
At present built solid poly aluminium chloride production equipment, majority be that bauxitic clay and calcium aluminate two-step approach are produced liquid poly aluminium chloride, then liquid poly aluminium chloride is dried with spraying or roller drying is the device of solid poly aluminium chloride.The following shortcoming of existing solid poly aluminium chloride production equipment ubiquity:
1) in the acid-soluble reaction of the first step and second step polyreaction, all can produce a large amount of insolubless and be difficult to separate with reaction solution, cause insolubles severe overweight in final solid poly aluminium chloride product;
2) although existing poly aluminium chloride production equipment generally adopts the press filtration device separates such as pressure filter to remove reaction insolubles residue, but, these pressure filter all do not have material-gathering device, the filter residue particularly separating for press filtration, generally directly fall earthward, getting up carries out again then to collect (normally manually using spade).This mode is polluted production environment, and artificially collect time-consuming, increase production cost; In addition, acid-soluble reacted pickling liquor meeting volatilizes the more sour waste gas that contains, and corresponding absorption disposal facility is not set when press filtration, can cause Working environment to worsen and environmental pollution;
3) in reaction, need to use the strongly-acid raw materials such as concentrated hydrochloric acid, not only reaction tank is had to strong corrodibility, and can volatilize in a large number containing sour waste gas, and existing reaction tank stopping property and acid resistance are not ideal enough, acid liquor leakage easily occur and containing sour waste gas effusion accident;
4) the roller drying device heat exchanger effectiveness using is not high, heats inhomogeneously, can not effectively utilize the heat energy of thermal oil, is unfavorable for energy-saving and cost-reducing and reduces discharging;
5) dehumidification system flow setting is reasonable not, causes energy consumption for drying high cost, and the transportation processing of the solid poly aluminium chloride of process roller drying also relatively wastes time and energy.
