Description
Vynález s-á týká zariadenia na získavanie elektrolytickej médi z měděných okují.The invention relates to a device for extracting an electrolytic medium from copper scale.
; ' Elektrolýzou sa katodická meď, vzniklá rozpuštěním měděných okují (CuO ,a CuO2) v kyselině sírovej získává róznymi spósobmi, napr. diskontinuálnym sposobom podl'a čs, autorského osvedčenia č. 234 328, ktorý spočívá v tom, že kyselina sírová, která vzniká pri elektrolytickom vylučovaní médi zo síranového elektrolytu opatovne reaguje za. přítomnosti peroxidu vodíka, pri súčasnom premiešaní vzduchom s kysličníkmi médi za vzniku síranu meďnatého, z ktorého je med' opatovne získávaná elektrolyticky. ; By electrolysis, cathodic copper resulting from the dissolution of copper scale (CuO, and CuO 2 ) in sulfuric acid is obtained in various ways, e.g. discontinuous way according to MS, author's certificate no. 234,328, characterized in that the sulfuric acid produced by electrolytic deposition of the medium from the sulphate electrolyte reacts cautiously. the presence of hydrogen peroxide, while mixing with air with the oxides of the medium to form copper sulfate, from which the copper is carefully recovered electrolytically.
Tento sposob sa; vykonává na zariadení, ktoré pozostáva z rozpúšťacej jednotky opatrenej perforovaným potrubím pre přívod vzduchu na priemiešovanie peroxidu vodíka s měděnými okújiami. Potrubím pre odvod síranu meďnatého je rozpúštacia jednotka přepojená cez filtračně zariadenie (odstraňovanie nežiadúcich nečistot) a výmenník tepla s elektrolysérom, na elektrolytické vylučovianie médi. Vyšší účinok sa dosahuje na polokontinuáinom zariadení, ktoré pozostáva z vyššie uvedených funkčných prvkov, u ktorého sú elektrolyséry zařáděné za sebou v sérii tak, že na každom z nich je iná prúdoivá hustota, zodpovedajúcazníženej komcentrácii Cu2+, aby sa mohla vylučovat kompaktná med. Přitom z posledného elektrolyséra, ktorý má najnižšiu koncentráciu Cu2+ v elektrolyte, je elektrolyt obsahujúci kyselinu sirovu opatovne privádzaný do rozpúšťacej jednotky pre rozpúšťanie okují. Nevýhodou tohoto polokontinuálneho sposobu je okrem potřeby sledovania minimálnej koncentrácie Cu2+ v jednotlivých elektroilyséroch i to, že elektrolyt je potřebné prevádzať z jedného elektrolyséru do druhého-.This way; Performed on a device consisting of a dissolution unit provided with a perforated air supply duct for mixing hydrogen peroxide with copper orbits. The copper sulphate drain line is a dissolution unit connected via a filter device (removal of unwanted contaminants) and a heat exchanger with an electrolyser, for electrolytic deposition by the medium. A higher effect is achieved on a semicontinuous device consisting of the above functional elements, in which the electrolysers are sequentially connected in series such that there is a different flow density at each of them, corresponding to a reduced Cu 2+ concentration in order to eliminate compacted honey. In this case, of the last electrolyzer having the lowest Cu 2+ concentration in the electrolyte, the electrolyte containing sulfuric acid is carefully fed to the dissolution unit for the scale dissolution. The disadvantage of this semicontinuous method is, besides the need to monitor the minimum Cu 2+ concentration in individual electro-lysers, that the electrolyte needs to be transferred from one electrolyser to another.
Uvedené nevýhody odstraňuje zariadenie na získavanie elektrolytické) médi z měděných okují, pozostávajúce z rozpúšťacej jednotky, filtračného zariadenia výmenníka tepla a elektrolyséra podfa vynálezu, ktoréhopodstata spočívá v tom, že elektrolysér je iónovou membránou rozdělený na katodový priestor a anodový priestor. Na katodový priestor je připojené potrubie pre přívod elektrolytu a anódo-vý priestor je přepojený s rozpúštacou jednotkou potrubím, pre odvod kyseliny sírovej.These disadvantages are overcome by an apparatus for obtaining an electrolytic medium from copper scales comprising a dissolution unit, a heat exchanger filter device and an electrolyser according to the invention, characterized in that the electrolyser is divided into an cathode space and an anode space by an ion membrane. An electrolyte feed line is connected to the cathode compartment and the anode compartment is connected to the dissolution unit by a conduit for the removal of sulfuric acid.
Výhody zariadenia podfa vynálezu sú v tom, že umožňujú efektívnejšie získavanie médi z uvedených okují kontinuálnym spósobom.The advantages of the device according to the invention are that they allow for more efficient extraction of the media from said scale in a continuous manner.
Příklad prevedenia zariadenia je znázorněný schematicky na priloženom výkrese.An exemplary embodiment of the device is shown schematically in the attached drawing.
Elektrolysér 5 je iónovou membránou fi predelený na katodový priestor 13 a anodový priestor 14, tento je potrubím 7 pre odvod kyseliny sírovej přepojený s rozpúštacou jednotkou 1.The electrolyzer 5 is divided by an ionic membrane fi into a cathode compartment 13 and an anode compartment 14, which is connected to the dissolution unit 1 via a sulfuric acid discharge line 7.
Rozpúšťacia jednotka 1 je spatné cez filtračně zariadenie 3, zachycujúce nežiadúce nečistoty v elektrolyte a výmenník tepla 4 přepojené potrubím 10 pre odvod síranu meďnatého s katodovým prlestorom 13 elektro-lyséru 5. Rozpúšťacia jednotka 1 je opatřená perforovaným potrubím 8 pře přívod vzduchu na premiešavanie peroxidu vodíka s kysličníkmi médi (měděnými okujamij za účelom zlepšenia oxidačněj reakcie. Zo spodnej časti upravenej rozpúšťacej jednotky 1 sa može vylúčená kovová med z měděných okují odvádzať do rozpúšťacieho zariadenia 2, do ktorého sa privádza kyselina sírová a peroxid vodíka, ich reakciou s med-ou dochádza k jej rozpúšťaniu, ktoré je urýchlené premiešavaním vzduchom privádzaným perforovaným potrubím 9 za vzniku síranu meďnatého. Tento sa může potrubím 11 napájat nia, přívod 10 síranu meďnatého privádzaného z rozpúšťacej jednotky 1 do katodového priestoru 13 elektrclyséru 5 alebo odvádzať vývodom 12 ku spracovaniu na kryštalický síran meďnatý.The dissolution unit 1 is visible through a filter device 3, trapping unwanted impurities in the electrolyte and a heat exchanger 4 connected by a copper sulphate discharge line 10 with a cathode space 13 of the electrolyzer 5. The dissolution unit 1 is provided with a perforated line 8 for air inlet for stirring hydrogen peroxide.
