The present invention relates to a device for carrying out electrochemical processes using a diaphragm between the electrodes, in particular for electrolytic oxidation, in particular the production of persulfuric acid and its compounds. , consisting of an electrolyzer comprising an electrolyte saint in this cathode and anode cell arranged thereon, the latter consisting of an anode space forming, suitably tubular diaphragm, enclosing a wire-shaped anode.

Uppfinningen kannetecknas i huvudsak darav, att anodcellen via diafragman j 5inte for tillforsel av anolyt tjanande rorledning 5ro fast anordnade i ett elekrolysorkarlet tackande lock, ovanfor vilket är anordnat ett en vatskeranna bildande samlingsrum for frail anodrummet uttradande, i dimform forekommande resp. mekaniskt medryckt syra jamte anodgas, och under vilket är anordnad en runtom utanfor katoden och anodcellen i elektrolyskdrlet nedskjutande vagg fOr uppsamling av katodgas for vars bortledning ett utlopp ãr anordnat, som passerar genom namnda lock. The invention can be characterized mainly in that the anode cell via the diaphragm is not arranged for supply of anolyte-serving pipeline 5ro fixedly arranged in an electrolyzer vessel filling lid, above which is arranged a collecting space forming a liquid for the frail anode space emerging in a mist form. mechanically entrained acid and anode gas, and below which is arranged a cradle projecting around the outside of the cathode and the anode cell in the electrolytic chamber for collecting cathode gas for the discharge of which an outlet is provided, which passes through said lid.

Ldmpligt är, att anodrummets volym, ut.tryckt i cm3, forhaller sig till diafragmaytan, uttryckt i cm2, som hogst 1 : 4, fOretradesvis 1 : 6 till 1 : 12, sasom i och for sig forut kant. It is conceivable that the volume of the anode space, expressed in cm 3, relates to the diaphragm surface, expressed in cm 2, which is at most 1: 4, preferably 1: 6 to 1:12, as per se leading edge.

Vid en foredragen utforingsform av uppfinningen är i locket innanfor den i elektrolyskfirlet nedskjutande vdggen anordnade ett antal anodceller, bildande ett cellsystem, varvid anodcellerna i anolythanseende antingen arc kopplade i serie med anolyttillforsel fran foregaende vatskeranna utom till den forsta, eller parallellt med anolyttillforsel frail gemensam tillforselledning, och 1 elektriskt hanseende aro kopplade parallellt, eventuelit med anvandande av gemensam katod for samtliga anodceller. In a preferred embodiment of the invention, a number of anode cells are arranged in the lid inside the wall projecting into the electrolytic sphere, forming a cell system, the anode cells in anolyte-standing position either arc connected in series with anolyte supply from the preceding water jug except to the first, or parallel to , and 1 electrically hanseende aro connected in parallel, possibly using a common cathode for all anode cells.

Vid en speciell utforingsform ár enligt uppfinningen i locket innanfor den i elektrolyskarlet nedskjutande vaggen anordnade ett flertal cellsystem, vilka i anolythanseende aro seriekopplade, varvid anolyttillfOrseln till samtliga cellsystem utom det forsta sker Iran en for samtliga anodceller i resp. cellsystem gemensam vitskeranna, men i elektriskt hdnseende aro parallellkopplade. In a special embodiment according to the invention, a plurality of cell systems are arranged in the lid inside the cradle projecting into the electrolytic vessel, which in anolyte-related array are connected in series, the anolyte supply to all cell systems except the first being Iran for all anode cells in resp. cell systems common vitskeranna, but in electrical terms aro parallel connected.

Uppfinningen beskrives narmare nedan under hanvisning till a bifogade rithingar visade utforingsexempel. The invention is described in more detail below with reference to the exemplary embodiments shown in the accompanying drawings.

Fig. 1 visar i vertikalsektion en enligt uppfinningen anordnad anodcell, dal. 1 betecknar en tradformig anod, som utefter hela sin langd omslutes av en rorformig diafragma 2. Med 3 betecknas katoden, som t. ex. bestar av bly och som är forsedd med en kylmantel 4, exempelvis av blyslingor. Elektroderna befinna sig i ett karl 5, i vilket katodvatskan rymmes och pafylles genom oppningen 16. Anolyten tillfores genom en rorledning 6 Over diafragmans undre oppning, sã att elektrolyten i det tranga diafragmaroret 2 vid elektrolysen medryckes uppat av de utvecklade anodgaserna. Anolyttilloppet regleras genom instdllning av en regleringsventil 15, medan nivan i elektrolyskdrlet halles konstant med hjalp av ett braddaylopp 17. Elektrolyskdrlet 5 dr tillslutet med ett lock 7, som enligt uppfinningen är fast forbundet med en utanfor katoden och anodcellen runtom i elektrolyskarlet nedskjutande vagg 8, t. ex. av Vinidur eller porslin, for uppsamling av det katodiskt utvecklade vatet, som bortledes genom ett utlopp 12, som 2— — passerar genom locket. Diafragman ar med hjalp av en bussning 9, som lampligen bestar av ett ej metalliskt material, t. ex. Vinidur, gastatt ford genom locket, varvid genomf0- ringen lampligen sakrats sarskilt exempelvis medelst en MipoIantatning. (Vinidur ar ett varumarke Or en i marknaden saluford polyvinylkloridplast och Mipolan fir ett sampolymerisat av vinylklorid och akrylsyraestrar.) Den ovanfor locket befintliga delen av vaggen ar utbildad som ett en vatskeranna 10 bildande samlingsrum for anolyten, som fran den ovre anden av diafragmaroret utslungas med den avgaende anodgasen, eventuellt som dim-ma. Den fran katodprodukten viii skilda anodgasen avledes genom ett ror 13. Vatskerannan 10, som bildar owe delen av locket ar forsedd med ett avloppsror 11 for den avgasade anolyten, som genom detta ror transporteras antingen till fortsatt bearbetning, exempelvis destillation, eller ocksa, sasom fig. 2 visar, vid seriekoppling av flera anoder ledes in i tillforingsroret av efterfoljande anodrum. Fig. 1 shows in vertical section an anode cell arranged according to the invention, dal. 1 denotes a wire-shaped anode, which along its entire length is enclosed by a tubular diaphragm 2. 3 denotes the cathode, which e.g. consists of lead and which is provided with a cooling jacket 4, for example of lead loops. The electrodes are located in a vessel 5, in which the cathode liquid is held and filled through the opening 16. The anolyte is fed through a pipeline 6 over the lower opening of the diaphragm, so that the electrolyte in the narrow diaphragm tube 2 is entrained by the developed anode gases during electrolysis. The anolyte inlet is regulated by setting a control valve 15, while the level in the electrolytic vessel is kept constant by means of a bradday passage 17. The electrolytic vessel 5 is closed with a lid 7, which according to the invention is fixedly connected to a rocker 8 outside the cathode and the anode cell. e.g. of Vinidur or porcelain, for collecting the cathodically developed water, which is discharged through an outlet 12, which 2— - passes through the lid. The diaphragm is aided by a bushing 9, which suitably consists of a non-metallic material, e.g. Vinidur, gassed through the lid, whereby the bushing is suitably secured separately, for example by means of a MipoIantatting. (Vinidur is a trademark of a polyvinyl chloride plastic marketed on the market and Mipolan for a copolymerization of vinyl chloride and acrylic acid esters.) the outgoing anode gas, possibly as a mist. The anode gas separated from the cathode product viii is discharged through a tube 13. The liquid jug 10, which forms the upper part of the lid, is provided with a drain pipe 11 for the degassed anolyte, which is transported through this tube either for further processing, for example distillation, or also as shown in FIG. 2 shows, in the case of series connection of several anodes, the following anode space is led into the supply pipe.

De i elektrolyscellerna anvanda elektroderna ha formen av tradar, och da i synnerhet s. k. manteltradar, vid vilka en karna av en elektriskt viii ledande metall, exempelvis silver eller koppar, overdragits med exempelvis tantal. Silver-tantalmanteltradar, som omlindats med platinaspiraler eller overdragits pa annat lampligt satt, ha visat sig sardeles lampliga for detta andamal. The electrodes used in the electrolytic cells are in the form of wires, and in particular so-called sheath wires, in which a core of an electrically conductive metal, for example silver or copper, is coated with, for example, tantalum. Silver tantalum mantle radars, which have been wrapped in platinum coils or coated in other appropriate ways, have proved particularly suitable for this purpose.

Med hjalp av lock-nedskjutande vaggkombinationen, som enligt uppfinningen bildar en vasentlig bestandsdel i elektrolysanordningen, bildas mellan det egentliga stromtillforingsstallet till anoden och till neddoppningsstallet I vatskan en eventuellt avsevard fri stracka, ph vilken anoden endast tjanar for stromtillforseln men ej for elektrolysen, medan den. star i beraring med den bildade anodprodukten. Det ar darfOr av betydelse att denna fria stracka Mlles sâ kall som m5jligt for undvikande av sonderdelningar hos anodprodukten genom de vid de hoga strombelastningarna i detta avsnitt av anoden avsevarda jouleska varmet. Anodens anslutning till den egentliga stromtillforingen, t. ex. en stromfordelarskena, astadkommes darfor genom lodning, for att en fullgod stromoverging och likformig stromfordelning skall astadkommas. Stromfordelarskenan kyles dessutom effektivt, varvid kylningen aven utovar sin verkan pa en vasentlig del av anodens fria stracka for att darigenom i stor utstrackning minska ett ogynnsamt inflytande av det jouleska varmet fran de starkt belastade tradarna pa anodprodukten eller att till och med fullstandigt eliminera detta varme. Den kylda stromtillforingen for anoden betecknas a fig. 1 med 14. With the aid of the lid-lowering rock combination, which according to the invention forms an essential component in the electrolysis device, a possible considerable free distance is formed between the actual current supply point to the anode and to the immersion point in the liquid, which anode only serves for the power supply but not for the electrolysis. . is in contact with the formed anode product. It is therefore important that this free stretch of Mlles be as cold as possible to avoid probe divisions of the anode product due to the joules of heat at the high current loads in this section of the anode. The connection of the anode to the actual power supply, e.g. a current distributor rail, is therefore provided by soldering, so that a satisfactory current transfer and uniform current distribution are achieved. In addition, the current distributor rail is cooled efficiently, whereby the cooling also exerts its effect on a substantial part of the free distance of the anode, thereby greatly reducing an adverse influence of the joules heat from the heavily loaded wires on the anode product or even completely eliminating this heat. The cooled current supply for the anode is indicated in Fig. 1 by 14.

Tidigare har det framhallits att uppfinningen sarskilt la.mpar sig for uppbyggandet av ett mera omfattande cellsystem med ett flertal i vatskehanssende serieanslutna anodcel ler. En dylik utfOringsform av den uppfinningsenliga anordningen visas a fig. 2, pa vii-ken hanvisningsbeteckningarna i huvudsak ha samma betydelse som pa fig. 1. Enligt fig. 2 upptar elektrolysbehallaren 5 anoder 1, vilka tin hela sin langd aro omslutna av diafragmaror 2. Samtliga diafragmaror 2 aro medelst gastata bussningar 9 fast fOrenade med locket 7. Katoderna 3, som kylas av kylslingor 4, aro anordnade hangs anoderna. Anolyten Mores genom rorledningen 6 och en samlingsledning 6a underifran I det till den forsta anoden harande anodrummet. For reglering av tillflodet i rorledningen. 6 tjanar en ventil 15, medan farsk katodvatska, t. ex. svavelsyra kan pafyllas genom en pafyllningsoppning 16. Det darvid katodiskt utvecklade vatet samlas under locket 7 innanf Or vaggen 8 och bortledes genom det gemensamma utloppet 12. Anodgaserna uttrada tillsammans med den anodiskt bildade persvavelsyran vid diafragmornas ovre ande i vatskernan 10 ovanfor locket och avledas genom roret 13, medan den avgasade anodvatskan nedstrommar genom roren 6 och Over samlingsledningen 6a i foljande anodrum Ater tillfores underifran. Pa detta salt uppnas en kontinuerlig vatskegenomgang genom anodrummen 1 Over vatskerannorna 10 och tilledningsroren 6 och 6a. Den bildade persvavelsyran fran den sista anoden ledes genom roret 11 till fortsatt bearbetning. De tradformiga anoderna uttrada genom det ovre, den uppskjutande vaggen tackande locket, som samtidigt bildar forslutningen till vatskerannan 10, och aro fast forbundna med de kylda anodskenorna 14, foretradesvis medelst lOdning. Katodvatskans nivâ installes med hjalp av ett braddavlopp 17. It has previously been pointed out that the invention is particularly suitable for the construction of a more comprehensive cell system with a plurality of anode cells connected in series at the watering hole. Such an embodiment of the device according to the invention is shown in Fig. 2, in which the reference numerals have substantially the same meaning as in Fig. 1. According to Fig. 2, the electrolysis container 5 occupies anodes 1, which tin are enclosed by diaphragms 2 throughout their length. All diaphragms 2 are fixedly connected to the cover 7 by means of gas-shaped bushings 9, and the cathodes 3, which are cooled by cooling coils 4, are arranged in the hanging anodes. The anolyte Mores through the pipe line 6 and a manifold 6a from below in the anode space belonging to the first anode. For regulating the inflow in the pipeline. 6 serves a valve 15, while fresh cathodic fluid, e.g. sulfuric acid can be filled through a filling opening 16. The thereby cathodically developed water collects under the lid 7 inside the cradle 8 and is discharged through the common outlet 12. The anode gases emit together with the anodically formed persulfuric acid at the upper end of the diaphragms in the water core 10 above the lid and 13, while the degassed anode liquid flows down through the pipes 6 and the collection line 6a in the following anode space Ater is supplied from below. On this salt, a continuous liquid passage is achieved through the anode spaces 1 above the water channels 10 and the supply pipes 6 and 6a. The persulfuric acid formed from the last anode is passed through the tube 11 for further processing. The wire-shaped anodes emerge through the upper cover of the projecting cradle, which simultaneously forms the closure of the watering can 10, and are fixedly connected to the cooled anode rails 14, preferably by soldering. The level of the cathode vat is installed with the help of a brad drain 17.

I synnerhet vid uppbyggande av en elektrolysanordning av ett flertal cellsystem omfattande med diafragmor omslutna tradformiga, foretradesvis langa anoder, som arbeta ph en katod, har det visat sig utomordentligt andamalsenligt att forena det som tillslutning av elektrolyskarlet anvanda locket, som samtidigt rymmer anordningarna for gas- och vatsketransporten, med diafragmorna till ett konstruktionselement, som ungefar i form av en ram lampligen ken inhangas som en enhet i det egentliga elektrolyskarlet. Genom en dylik konstruktion blir monteringen av elektrolyscellerna sardeles enkel, tidsbesparande och tillfOrlitlig (jfr fig. 3 i forbindelse med fig. 4). Det framgar alltsa, att den av locket 7 och vaggarna 8 bestaende enheten, tillsammans med anoderna och diafragmarOren 1 och 2, avensom vatskerannorna 10, gasavledningsroren 12 och 13 och roren 6 fOr elektrolytaterlopp bilda en konstruktiv enhet, pa sá salt, att alla dessa delar i en operation kunna insattas i eller avlagsnas ur elektrolyskarlet mellan katoderna och kylslingorna. Particularly in the construction of an electrolytic device of a plurality of cell systems comprising diaphragm-enclosed wire-shaped, preferably long anodes, which operate on a cathode, it has proved extremely expedient to combine it using the lid as a closure of the electrolytic vessel, which at the same time holds the devices for gas. and the liquid transport, with the diaphragms of a structural element, which in the form of a frame is suitably hung as a unit in the actual electrolyte vessel. Due to such a construction, the assembly of the electrolysis cells becomes extremely simple, time-saving and reliable (cf. Fig. 3 in connection with Fig. 4). It can thus be seen that the unit consisting of the cover 7 and the cradles 8, together with the anodes and diaphragms 1 and 2, as well as the water channels 10, the gas discharge pipes 12 and 13 and the pipes 6 for electrolyte inlet form a structural unit, so that all these parts in an operation can be inserted into or removed from the electrolytic vessel between the cathodes and the cooling coils.

Vid framstallning av persvavelsyra, i synnerhet genom anvandning av hoga stromkon- , centrationer, mojliggor uppfinningen ett snabbt uppnaende av hoga slutkoncentratio- ner somett fordelaktigt satt minska ang- forbrukningen vid destillationen for den fortsatta bearbetningen till vatesuperoxid. Med hansyn till det ogynnsamma inflytandet av Caro's syra är den Rade bildningshastigheten av persvavelsyran och den korta upphallstiden i anodrummet av sarskild betydelse. In the production of persulfuric acid, in particular through the use of high stream concentrations, the invention enables a rapid attainment of high final concentrations which has advantageously reduced the steam consumption in the distillation for the further processing into hydrogen superoxide. In view of the unfavorable influence of Caro's acid, the rate of formation of persulfuric acid and the short residence time in the anode space are of particular importance.

Den tvangsmassiga vatsketransporten astadkommer framfor alit vid seriekoppling av flera cellsystem en utomordentligt liten temperaturkanslighet hos anolyten och medfor aven att regleringen av det anodiska tillflodet och avtappningen av den bildade persvavelsyran under avsevard forenkling av den driftsmassiga skotseln av anlaggningarria numera endast sker pa ett stalle. I detta sammanhang ma framhallas att den vanliga avgasningen av anolyten vid en med ett flertal anoder genomford elektrolys numera utfores pa ett f8rdelaktigt satt och att okningen ay genomstromningsmangderna tillater en noggrannare och mindre kanslig dosering ay elektrolyten. Alltefter koncentrationen pa den anvanda syran forblir cellspanningarna pa 4,5 volt och darunder utomordentligt sma, sâ att man genom minskningen av spanningen och mojligheten att utfOra elektrolysen med hoga stromutbyten kan uppna avsevarda energibesparingar av 20-30 % i ja.mforelse med de for liknande andamal avsedda kanda eller fOreslagna forfarandena, vid -vilka man arbetar med vasentligt lagre stromkoncentration och eventuellt till och med sarskild anodkylning. Compulsory liquid transport, above all in the case of series connection of several cell systems, results in an extremely small temperature sensitivity of the anolyte and also means that the regulation of the anodic inflow and the draining of the formed sulfuric acid while considerably simplifying the operational part of the plant only now. In this connection it should be emphasized that the usual degassing of the anolyte in an electrolysis carried out with several anodes is now carried out in an advantageous manner and that the increase in the flow rates allows a more accurate and less probable dosing of the electrolyte. Depending on the concentration of the acid used, the cell voltages remain at 4.5 volts and below extremely low, so that by reducing the voltage and the possibility of performing the electrolysis with high current yields, considerable energy savings of 20-30% can be achieved compared to those for similar intended intended kanda or the proposed procedures, in which one works with substantially lower current concentration and possibly even special anode cooling.

Uppbyggnaden ay varje cellsystem av ett flertal anodceller framgar av den i fig. 3 och 4 visade konstruktionen av en elektrolysOr med 7 cellsystem med vardera 40 anodceller. Beteckningarna i fig. 3 och 4 ha foljande betydelse Anodtradar (7 x40) DiafragmarOr (7 X 40) Katoder (7 X 1) Kylslingor f5r katoder Elektrolysorvanna Tillforselledning for anolyten for matning ay 40 anodceller 6a. Samlingsledningar for anolyten Elektrolysorlock Nedskjutande vagg for uppsamling av katodiskt utvecklat vale Bussning for diafragmarorens genomforing Vatskerannor vid locket Avledningsror for anolyt Utlopp for mate Avledningsror for anodgaser (4) Stromskenor for anodtradarna Tackplatar for anolytrannorna (10) Tillforingsr5r for katodrummet Braddavlopp fOr bortledning av katodvatskan. The structure of each cell system of a plurality of anode cells is apparent from the construction of an electrolyzer of 7 cell systems with 40 anode cells each shown in Figures 3 and 4. The designations in Figures 3 and 4 have the following meaning Anode radar (7 x 40) Diaphragms (7 X 40) Cathodes (7 X 1) Cooling coils for cathodes Electrolyzer surface Supply line for the anolyte for feeding ay 40 anode cells 6a. Collecting lines for the anolyte Electrolyzer lid Downwardly projecting cradle for collecting cathodically developed whale Bushing for the diaphragm tube's bushing Water ducts at the lid Drain pipe for anolyte Outlet for feed Discharge pipe for anode gases (4)

Av denna anordning framgar, att det, sâ- som redan framhallits, är mojligt att utnyttj a gastransporten for elektrolyten i det att ett flertal cellsystem aro seriekopplade i ett och samma plan utan kaskadformig uppbyggnad, Den snabba omsattningen av anodvatskan ge- ,nom diafragmarummen, som exempelvis vid sju seriekopplade cellsystem sker med en str5mningshastighet av 1,4 m/min, gOr det for forsta &Igen mojligt att uppna en persvavelsyrakoncentration av Over 300 g/lit. Man er- hailer i genomsnitt en anodprodukt med 330-- 350 g persvavelsyra per liter yid ett stromutbyte av mer an 70 %, varvid fOrbrukningen, raknad pa 1 kg 100-procentig vatesuperoxid, Jigger under 12, i nornaala fall till och med vid 11 kWh. From this device it appears that, as already pointed out, it is possible to utilize the gas transport for the electrolyte in that several cell systems are connected in series in one and the same plane without a cascade-shaped structure. The rapid conversion of the anode liquid through the diaphragm spaces, as, for example, in seven series-connected cell systems takes place at a flow rate of 1.4 m / min, it is for the first time again possible to achieve a press sulfuric acid concentration of Over 300 g / liter. An anode product with an average of 330-350 g of persulfuric acid per liter is obtained with a current yield of more than 70%, the consumption, calculated on 1 kg of 100% hydrogen peroxide, jigger below 12, in normal cases even at 11 kWh.

En sarskild fordel med den enligt uppfinningen foreslagna anordningen for utforande ay elektrolysen ligger dari, att samlingsrmnmet for den fran anodrummen i ett cellsystem uttradande anodsyran forenas med anodrummen av det foljande cellsystemet genom en gemensam ledning (6 resp. 6a). Som en vasentlig teknisk effekt hos de anyanda anordnin.garna ma vidare namnas, att anolyten ror sig i motstrom mot katolyten, varigenom man vid framstallningen avpersvavelsyra mom omradet for det hogsta behovet av HS0'4-joner i anodrummet aven liar den h8gsta H2SO4-koncentrationen i katodrummet. Genom dessa forhallanden ges en vasentlig forutsattning for uppnaende av hoga koncentrationer ay persvavelsyra i anodpunkten. I jamforelse armed har det vid den hittills vanliga kaSkadformiga anordningen am cellerna ej varit m5jligt att genomfora en dylik atgard, utan liar stred tvartom det hogsta behovet am HSO4'-joner alltid mot den kraftigast utarmade katodvatskan. A particular advantage of the device for carrying out the electrolysis proposed according to the invention lies in the fact that the collecting space for the anode acid emanating from the anode spaces in a cell system is united with the anode spaces of the following cell system by a common line (6 and 6a, respectively). As a significant technical effect of the other devices, it may further be mentioned that the anolyte moves in countercurrent to the catholyte, whereby in the production of sulfuric acid the area for the highest need of HSO'4 ions in the anode space is obtained even at the highest H2SO4 concentration. in the cathode compartment. These conditions provide an essential precondition for achieving high concentrations of persulfuric acid at the anode point. In comparison with the hitherto usual cascade-shaped device in the cells, it has not been possible to carry out such an action, but on the contrary the highest need for HSO4 'ions has always been against the most heavily depleted cathode liquid.
