| 简介 |
Proposed useful model relates to the field of metallurgy of non-ferrous metals and can be used in titanium production for complex hydro metallurgical processing, decontamination and decontamination of much component polymetallic wastes production of titanium, as technogenic raw materials with extraction of valuable components, produce various commercial products and neutralization of the resulting secondary wastes. The structural useful invention is directed at solving the problem, in diffusion Aras operation efficiency of technological separation of-improvement of its quantitative and qualitative values. Technical result, which can be obtained at implementation of the proposed utility model, consists in diffusion Aras degree of purification of furnace exhaust gases RTP from of finely dispersed dust, containing toxic and radioactive metals, prevention of pollution of environment and zones of working compartments harmful substances, expansion nomenclature commodity products at preservation of all other advantages known technical solutions, including of the prototype-possibility of processing, of and deactivation of secondary production wastes in ecologically safe form, suitable for long-term storage. Process separation of for hydro metallurgical of processing and deactivation of technogenic raw materials to produce commercial products, including bath hydro removing waste melts of titanium chlorinators, with supply system nitrogen for mixing pulp formed, hydro settler, circulating tank, having connection with tanks macrocomponent solutions of sodium sulfite and barium chloride, while lower discharge of circulation tank has connection with filter-press-i for isolating from pulp insoluble residue and radioactive sediments of sulfates of barium/calcium, output of clarified solution is directed into tank-collector, connected to the reactor for deposition of sum of hydro ksidov chromium, iron, and trace rare metals, upper branch pipes of which have connection with tanks-macrocomponent solutions of alkali reagent and high-molecular flocculant, and drain fitting pipe is directed on filter-press-ii for isolating from pulp sum of hydro ksidov chromium, iron, and trace rare metals, output chloride solution from filter press is directed into reactor for deposition of oxyhydrates of iron and manganese, equipped with device for supply of compressed air, the upper branch pipes of reactor connected with tanks-macrocomponent solutions hydro ksida sodium and sodium hypochlorite, and branch pipe lower drain forms connection with filter-press-iii for isolating from pulp of oxyhydrates of iron and manganese, a trough filter-press-iii has connection with tank- repulpatorom precipitate of oxyhydrates of iron and manganese, output insoluble residue and sulfates of barium/calcium from trough filter-press-i is directed through locking device in screw mixer, connected with hopper-batcher dust from ore-smelting furnace smelting ilmenite concentrates and branch pipe unloading device hydro settler, and output is directed in the second screw mixer, connected to bin initial magnesium-containing oxide materials, tank dosing of solution and/or pulp magnesium chloride and with unit moulding, heat treatment and pressing composite mixture. Novelty is, that process separation of for hydro metallurgical of processing and deactivation of technogenic raw materials to produce commercial products additionally has system of purification of powder-gas mixture the process of ore-smelting reduction smelting ilmenite concentrates, including two successively interconnected cyclone and vodooroshaemyi scrubber with ball movable nozzle, provided with installed in the upper part of the absorber drop catcher (entrainment separator) and vodorazbryzgivayushchim device, and in the lower part of the absorber-hydro distributing grate, located above inlet branch pipe of cyclone, drain branch pipe suspension from scrubber has connection with circulation tank, made in form of thickener, plum thickened pulp from which is directed into mixing hopper-batcher, and branch pipe drain clarified liquid sti has connection with vodorazbryzgivatelem scrubber and tight screw feeder, input of which is connected via shutoff valves with discharging device cyclones, and output uvlazhennoi dust from auger feeder naprvlen into mixing hopper-batcher of moistened dust, connected with hopper-batcher dust from ore-smelting furnace smelting ilmenite concentrates. |
