Description
467 485 2 miljöfarliga substanser eller miljöfarligt avfall, utan kan hanteras på konventionellt sätt. 467 485 2 environmentally hazardous substances or environmentally hazardous waste, but can be handled in a conventional way.
Uppfinningen hänför sig således till ett förfarande för destruktion av en halogenhaltig substans, såsom en substans av typen halogenkarbon eller en klorerad organisk substans, genom oanvancilirxg av substansen, där den halogen- haltiga substansen bringas att reagera med flytande järn och. bilda järnsalt/- er genom att tillföras ett järnbad tillsammans med syrgas och/eller syrehal- tigt material.The invention thus relates to a process for the destruction of a halogen-containing substance, such as a halogen-carbon-type substance or a chlorinated organic substance, by unvancilitating the substance, wherein the halogen-containing substance is reacted with liquid iron and. form iron salt (s) by adding an iron bath together with oxygen and / or oxygen-containing material.
Förfarandlet utnärks särskilt av, att nämnda järnsalt/-er bringas att avgå från badet i ett från järnbadet avgående flöde av stoft och gas, samt av, att vätehalogenider bringas att bildas, genom att vätgas och/eller vätehal- tigt material tillförs järnbadet och/eller nämnda stoft- och gasflöde.The process is characterized in particular by causing said iron salt (s) to leave the bath in a flow of dust and gas leaving the iron bath, and by causing hydrogen halides to be formed by supplying hydrogen gas and / or hydrogen-containing material to the iron bath and / or or said dust and gas flow.
Nedan besln-ivs *uppfinningen närmare i anslutning till utförillgsexeltapel samt bifogade ritning, där - fig. 1 schematiskt visar en utföringsform av en anläggning för utförande av ett förfarande enl. uppfinningen.The invention is described in more detail below in connection with the discharge axis table and the accompanying drawing, in which - Fig. 1 schematically shows an embodiment of a plant for carrying out a method according to the invention.
Vid den i fig. 1 visade anläggningen betecknas med 1 en reaktor, ett reaktorkärl, med ett järnbad 2, en utloppsöppning 3 samt injektionsmunstyclcen 4, vilka här, såsom ett exenpel, är bottenplaoerad och vilka är anordnade för injektion av syrgas 5 eller motsvarande, tillsatsbränsle 6, såsom kol 6, samt halogenhaltig/-a substans/-er 7. Med 8 betecknas reaktionszoner löpande upp genom järnbadet och med 9 betecknas en flytande slagg.In the plant shown in Fig. 1, 1 denotes a reactor, a reactor vessel, with an iron bath 2, an outlet opening 3 and the injection nozzle 4, which here, as an example, are bottom-plowed and which are arranged for injection of oxygen 5 or the like, additive fuel 6, such as carbon 6, and halogen-containing substance (s). 7 denotes reaction zones running up through the iron bath and 9 denotes a liquid slag.
Syrgasen 5 utgör här oxidationslnedium för oxidation av kolet ingående i den/de för destruktion avsedda substansen/-erna. Som oxidationslnediurn kan annat syrehaltigt material, såsom järmlalln, tänkas, liksom kornbillationer av syrgas och annat syrehaltigt material. Föredraget är ofta att syrgas een/eller syreneltigt mteriel tillförs i väsentligen stöldanetriele :längder i relation till total mängd tillfört kol, vilket innefattar i form av rlämrlda Substans/-er tillfört kol.The oxygen gas 5 here constitutes the oxidation medium for oxidation of the carbon contained in the substance (s) intended for destruction. As the oxidation medium, other oxygen-containing materials, such as iron alloys, are conceivable, as are grain billions of oxygen and other oxygen-containing materials. It is often preferred that oxygen and / or oxygen-like material be supplied in substantially stolen non-material lengths in relation to the total amount of carbon supplied, which comprises in the form of residual substance (s) added carbon.
För vissa tillämpningar förefinns även möjlighet till tillförsel av väte- 467 485 3 haltigt material, såsom vissa slag av kolpulver, vätgas, vatten etc. för bildning av väteförenixxgar, främst syror.For certain applications there is also the possibility of supplying hydrogen-containing material, such as certain types of carbon powder, hydrogen gas, water, etc. for the formation of hydrogen compounds, mainly acids.
Tillförsel av tillskottsbränsle 6 sker vid behov av enecrgitillskott. Bränslet 6 kan utgöras av exempelvis kol i form av kolpalver och/eller kolväten såsom propan.Supplementary fuel 6 is supplied when energy supplementation is required. The fuel 6 may consist of, for example, carbon in the form of carbon pellets and / or hydrocarbons such as propane.
Halogenerna i den halogenhaltiga substansen, den "miljöfarliga" substansen, reagerar med järn i järnbadet, varvid järnhalogeraider bildas, vilka kan deponeras eller camvandlas till syror med t.ex. vatten i ett senare process- steg, vilka syror kan hanteras på konventionellt sätt. I denna form är halogenenia ej längre att betrakta som miljöfarligt förekommande.The halogens in the halogen-containing substance, the "environmentally hazardous" substance, react with iron in the iron bath, whereby iron halides are formed, which can be deposited or cam-converted to acids with e.g. water in a later process step, which acids can be handled in a conventional manner. In this form, halogenenia is no longer considered to be environmentally hazardous.
Halogenkarboner innehåller ofta klor (Cl), fluor (F) eller brcm (Br) förutom kol (C). Reaktionsförloppet avseende auvandlizmg av halogenkarborxer kan schematiskt beskrivas med den generella reaktionen (1) , Fe(l) + CXyfl/g) + 0,5 02(9) = FeXyß/l) + C0(9) (1) där (s), (l), (g) fast, flytande resp. gasformig fas och CXY är en halogenkarbon. Eïxemnpel på sådana föreningar återfinns i tabell 1. Reaktions- förloppet för några av dessa föreningar fraxngår av reaktionerna (2) och (3) .Halocarbons often contain chlorine (Cl), fluorine (F) or brcm (Br) in addition to carbon (C). The course of the reaction with respect to the evolution of halocarboxes can be schematically described by the general reaction (1), Fe (1) + CXy fl / g) + 0.5 O 2 (9) = FeXyß / l) + CO (9) (1) where (s) , (l), (g) solid, liquid resp. gaseous phase and CXY is a halogenated carbon. Examples of such compounds are given in Table 1. The course of the reaction of some of these compounds is derived from reactions (2) and (3).

Huvudsakligsn bildas Faciz, Faarz och FsF3. Bildade jårnsaltsr avgår sålunda från järnbadst 2 i att flöde 10 av stoft och gas. Under ett förlopp, där reaktionsprodukterïla länmar järnbadet, avkyls och avskiljs, komner dessa att från kondenserad form övergå till ett fast stoft. Föreningarnas tillstånd vid olika temperatu- rer framgår av Tabell 2.Compound Chemical formula cFc 11 cc13F cFc 12 cclzFz om: 113 cclzF - cciFz cFc 114 cclFz - ociFz CFC 115 0C1F2 - CF3 Hcfc 22 c fi clrz Halon 1202 CBrZFZ Halon 1211 CBrCIFZ Halon 1301 cF2 6F + 2 soo + 9Fec1_-¿+ 2FeF3 (2) 467 485 zcßrF3 + sns + oz = zoo + Fsßrz + zFeF3 (s) co2 + c = zoo (4) When the halogen carbons come in contact with an iron bath at a tenrperatxxr of 1soo ° c is thus formed iron salt and gas. Faciz, Faarz and FsF3 are mainly formed. Formed iron salts thus depart from iron bath 2 in the flow of dust and gas. During a process in which reaction products leave the iron bath, cool and separate, these will change from a condensed form to a solid. The condition of the compounds at different temperatures is shown in Table 2.

Vissa av de föreningar scan skall destrueras utvecklar inte tillräckligt med värme för att förfarandet skall vara autogent. Eftersom reaktion (4) är loraftigt förskjutsn åt högar madar batmgaissna i janmadst kan inte all energi, som skall tillföras järnbadet för att kcmnpensera för endoteJnna reaktioner, entalpi i avgas och reaktor-förluster, tillföras genom oxidation av ingående kol, C, till kolmonoxid, CO. Det finns olika sätt att kompensera processen för energikrävande reaktioner. Ett sätt är att ovanför badytan bränna kolmonoxiden med syrgas eller annat oxidationsmedium och på så sätt utveckla erforderligt värme i reaktorn, vilket sålunda är avsett att medverka till täckande av för destrulctioneza erforderlig energi. Härvid tillförs således stoft- och gasflödet 10 syrgas och/eller syrehaltigt material. Ett annat sätt är att förgasa något bränsle i processen, t.ex. kolpulver och 'x 467 483 5 på detta sätt tillföra energi. Det kommer då samtidigt för vissa slag av kolpulver att frigöras vätgas, som reagerar med halogenerna till HBr, HCl och HF. Mer allmänt kan sägas att vätehalogenider kan bildas genom att vätgas Och/eller Vätehaltigt material tillförs järnbadet och/eller rlämrxia stoft- och gasflöde.Some of the compounds scan to be destroyed do not generate enough heat for the process to be autogenous. Since reaction (4) is loraftically displaced to the heaps of the baths in January, not all energy to be supplied to the iron bath to compensate for endothelial reactions, enthalpy of exhaust gas and reactor losses, can be supplied by oxidation of the carbon, C, to carbon monoxide. CO. There are different ways to compensate for the process of energy-intensive reactions. One way is to burn the carbon monoxide above the bath surface with oxygen or other oxidation medium and thus develop the required heat in the reactor, which is thus intended to help cover the energy required for destrulctioneza. Thus, the dust and gas flow 10 is supplied with oxygen and / or oxygen-containing material. Another way is to gasify some fuel in the process, e.g. carbon powder and 'x 467 483 5 in this way supply energy. Hydrogen, which reacts with the halogens to HBr, HCl and HF, will then be released simultaneously for certain types of carbon powder. More generally it can be said that hydrogen halides can be formed by adding hydrogen gas and / or hydrogen-containing material to the iron bath and / or reducing the flow of dust and gas.
Vid den visade anläggningen förefinns en första gasledning 11 för stoft- och gasflödet, vilken löper från reaktorn 1 till en första s.k. våtslmlbber 12, i vilken kylnirmg och stoftavskiljning är avsedd att ske, samt en andra gasledning 13 för stoft- och gasflödet, Vilken löper från den första 12 till en andra våtslmJbber 14, i Vilken och Stoftavskilj- ning är avsedd att ske. För vätska, i huvudsak vatten, vilken avrinner från den första slofubbern 12, förefinns en avskiljare 15, såsom en lamellav- skiljare 15, för partiklar samt en efter avskiljaren anordnad sedimenterirxgs- anordningie, såsdnenbassäng. Förvätskafråndenarxdraskrwibbernnz förefinns en korxditionerizigsanordnirxg 17 innefattande en tank där pH- justering medelst, i detta fall, natrimnhydroxid, NaOH, sker, innan vätskan tillförs sedimenteringstanken 16, vilken även tillförs kalciumhydroxid, Ca(OH)2. Från tanken 16 kan kalciuunhalogerlider och rent vatten uttagas.At the plant shown, there is a first gas line 11 for the dust and gas flow, which runs from the reactor 1 to a first so-called wet slurries 12, in which cooling and dust separation are intended to take place, and a second gas line 13 for the dust and gas flow, which runs from the first 12 to a second wet slurries 14, in which and dust separation is intended to take place. For liquid, mainly water, which drains from the first sludge fiber 12, there is a separator 15, such as a lamella separator 15, for particles and a sedimentation device arranged after the separator, the sowing basin. There is a corrosion detection device 17 comprising a tank in which the pH adjustment by means of, in this case, sodium hydroxide, NaOH, takes place before the liquid is fed to the sedimentation tank 16, which is also fed with calcium hydroxide, Ca (OH) 2. Calcium halide sludge and pure water can be taken from tank 16.
Från den andra våtskrubbern 14 utlöper renad gas och passerar härvid enl. det visade exemplet, en droppavskiljare 18 och en :nätstation 19.From the second wet scrubber 14 purified gas flows out and in this case passes according to the example shown, a drip separator 18 and a network station 19.
Ett exempel på destruktion av halogenhaltigt organiskt material framgår nedan.An example of destruction of halogen-containing organic material is shown below.
Ett ton per tiJnme av det halogenhaltiga materialet halon 1301 injioeras i ett 10 tons järnbad i en reaktor tillsammans :med 75 m3n oxygen. För att inte ackumulera kol i järnbadet tillförs en Stökioïnetrisk syrgas genom munstycken i reaktorns vägg. Förgasning av kolet sker i jämbadet, genom en partiell förbränning av tillfört kol, som härvid bildar kolmnoxid.One tonne per hour of the halogen-containing material halon 1301 is injected into a 10 tonne iron bath in a reactor together with 75 m3n of oxygen. In order not to accumulate carbon in the iron bath, a stoichiometric oxygen is supplied through nozzles in the wall of the reactor. Gasification of the carbon takes place in the iron bath, by a partial combustion of added carbon, which in this case forms carbon oxide.
Det tinförda naterialet har en kart uppehåiistid i järnbadet (< 1 s) men bryts ned effektivt p.g.a. den extremt goda värmeöverföriragen samt den höga nedeltefperatmlren i jäznbadet, 1soo° c (lokalt zooo - z3oo° c) . net kommer att bildas 726 kg Feßrz, 159 kg Feæg samt iso nån co. Efter det att gas och stoft har lämnat järnbadet passerar de en gasledning innan kylning och stoftavskiljning sker i en våtskrubber. Ingångstenperaturen på gasen vid är c:a 1200° C och den totala uppehållstiden för gas och stoftisystexnetirmanslmzbberriärz-5sberoendepågasflödeochtryck. 467 483 för en effektiv och homogen nedbrytning av organiskt material är sålunda mycket goda i denna process.The tin-lined material has a short residence time in the iron bath (<1 s) but degrades effectively due to the extremely good heat transfer properties and the high downflow rate in the iron bath, 1soo ° c (locally zooo - z3oo ° c). net will be formed 726 kg Feßrz, 159 kg Feæg and iso nån co. After gas and dust have left the iron bath, they pass a gas line before cooling and dust separation takes place in a wet scrubber. The inlet stone temperature of the gas at is about 1200 ° C and the total residence time of gas and dust ice system does not depend on gas flow and pressure. 467 483 for an efficient and homogeneous decomposition of organic material are thus very good in this process.
Förfarandet enl. uppfinningen torde till väsentlig del framgått ovan. Under utnyttjannie av hög temperatur och god vänneöverförixlg i ett järnbad bringas således det aktuella halogenhaltiga miljöfarliga materialet att omsättas till jämsalt/-er, vilket/-a efter konventionell behandling kan släppas ut, återvinnas eller deponeras och vilket/-a sålunda ej utgör miljöfarligt avfall.The procedure according to the invention should be substantially apparent from the foregoing. Thus, during the use of high temperature and good friend transfer in an iron bath, the halogen-containing environmentally hazardous material in question is converted into iron salt (s), which after conventional treatment can be released, recycled or disposed of and which thus does not constitute environmentally hazardous waste. .
Såsom torde framgått ovan erbjuder Llppfirmingen ett förhållandevis enkelt och :tycket effektivt sätt att onmänaertaga naiogennaitigt miljöfarligt avfall.As will be seen above, the Llppfirmingen offers a relatively simple and very efficient way of removing non-environmentally hazardous waste.
Ovan har uppfinningen beskrivits i anslutning till utförirxgsexetrpel.The invention has been described above in connection with an exemplary embodiment.
Naturligtvis kan fler utföringsformer och mindre förändringar tänkas, utan att Lzppfinningstanken därför frångås.Of course, more embodiments and minor changes are conceivable, without departing from the concept of invention.
Vidare kan, såsom torde framgått ovan, efterbehandling av stoft- och gasflödet göras på annat sätt än det som visas i fig. 1.Furthermore, as will be seen above, post-treatment of the dust and gas flow can be done in a different way than that shown in Fig. 1.
Den halogenhaltiga substansen kan tillföras jämbadet genom injektion under järnbadets överyta och/eller injektion uppifrån mot järnbadets överyta.The halogen-containing substance can be added to the iron bath by injection below the upper surface of the iron bath and / or injection from above against the upper surface of the iron bath.
Enligt ett utförande bringas miljöfarliga substanser i gas- och stoftflödet att oxidera genom tillförsel av syrgas och/eller syrahaltigt material.According to one embodiment, environmentally hazardous substances in the gas and dust flow are caused to oxidize by the supply of oxygen and / or acid-containing material.
Enligt ett utförande upphettas stoft- och gasflödet i en efterbrärmingszon för att säkerställa att inga miljöfarliga substanser kvarstår efter destruk- tionen. Upphettnirxgen sker på länpligt sätt medelst syrgas-gasol, plasma eller liknande. Destrulctionen kan ske vid atmosfärstryck eller över- atmoefäi-iskt tryck.According to one embodiment, the dust and gas flow is heated in an afterburning zone to ensure that no environmentally hazardous substances remain after the destruction. The heating is carried out in a linkable manner by means of oxygen-gas, plasma or the like. The destruction can take place at atmospheric pressure or super-atmospheric pressure.
Enligt ett i vissa fall föredraget utförande bringas stoft- och gasflödet passera en torr eller våt/torr gasreraing, där kalciumföreningar tillsätts för att absorbera vätehalogerzider. 1*- 467 483 7 Ilppfiamizgen skall således ej anses begränsad till ovan angivna utförings- fonner utan kan varieras inom sin av bifogade patentkrav angivna ram.According to a in some cases preferred embodiment, the dust and gas flow is passed through a dry or wet / dry gas ring, where calcium compounds are added to absorb hydrogen halides. 1 * - 467 483 7 Ilppfiamizgen shall thus not be considered limited to the above-mentioned embodiments but may be varied within its scope as set out in the appended claims.
