Description
453 863 f l. 453 863 f l.
I injiceras i den upphettade gasen och varvid förhållandet mellan injicerat avfallsmaterial och oxídationsmedel regleras så att kvoten C02/CO + C02 är mindre än 0,1.I is injected into the heated gas and the ratio between injected waste material and oxidizing agent is regulated so that the ratio CO 2 / CO + CO 2 is less than 0.1.
Enligt en föredragen utföringsform av uppfinningen genom- föres förbränningen vid en temperatur överstigande cirka 14oo°c.According to a preferred embodiment of the invention, the combustion is carried out at a temperature exceeding about 140 ° C.
Fördelen med destruktion vid hög temperatur, dvs. före- trädesvis över cirka 1400°C, i en atmosfär innehållande ett underskott av oxidationsmedel, är att den höga tem- peraturen i processen leder till snabb och fullständig sönderdelning av avfallsmaterialet i mindre farliga äm- nen sàsom CO, C02, H2, H20, HCl och C12.The advantage of destruction at high temperature, ie. preferably above about 1400 ° C, in an atmosphere containing a deficit of oxidizing agent, is that the high temperature in the process leads to rapid and complete decomposition of the waste material into less hazardous substances such as CO, CO 2, H 2, H 2 O, HCl and C12.
Den vid konventionella processer förekommande àterbild- ningen av giftiga, miljöfarliga ämnen, motverkas av så- väl den höga temperaturen, det rådande syreunderskottet som den korta uppehållstiden. Uppehållstiden uppgår till i storleksordning cirka 0,5 - l sekund.The regeneration of toxic, environmentally hazardous substances in conventional processes is counteracted by the high temperature, the prevailing oxygen deficit and the short residence time. The residence time is in the order of about 0.5 - 1 second.
Genom att för processen erforderliga värmeenergin till- föres medelst en i en plasmagenerator upphettad gas, säkerställes under driftsförhâllanden den erforderliga höga temperaturen i processen. I plasmageneratorn över- föres elektrisk energi till värmeenergi i en lämplig gas, i en ljusbàge, som alstras i plasmageneratorn.By supplying the heat energy required for the process by means of a gas heated in a plasma generator, the required high temperature in the process is ensured under operating conditions. In the plasma generator, electrical energy is transferred to heat energy in a suitable gas, in an arc, which is generated in the plasma generator.
Gasen kan exempelvis utgöras av åtminstone en del av det oxidationsmedel som tillföres i reaktionskammaren.The gas may, for example, be at least a part of the oxidizing agent supplied to the reaction chamber.
Oxidationsmedlet kan utgöras av en gas innehållande exempelvis luft, syrgas (02), koloxid (C02) och/eller vattenånga (H20), som sålunda helt eller delvis kan till- föras processen genom plasmageneratorn. Reaktionskammaren 453 863 L. v utgöres av en sluten, värmeisolerad, eldfast infodrad behållare, försedd med anslutningar för en eller flera plasmageneratorer, injiceringslansar för avfallmaterialet och oxidationsmedel samt ett utlopp för den genererade gasen.The oxidizing agent may be a gas containing, for example, air, oxygen (O 2), carbon monoxide (CO 2) and / or water vapor (H 2 O), which can thus be supplied in whole or in part to the process through the plasma generator. Reaction chamber 453 863 L. v consists of a closed, heat-insulated, refractory lined container, provided with connections for one or more plasma generators, injection lances for the waste material and oxidizing agent and an outlet for the generated gas.
Från reaktionskammaren införes den genererade gasen i en tvättanordning, i vilken gasen kyles och alla klorinne- hållande föreningar avskiljes.From the reaction chamber, the generated gas is introduced into a washing device, in which the gas is cooled and all chlorine-containing compounds are separated.
Den från klor befriade gasen kan sedan införas i en slutför- bränningskammare alternativt användas direkt i en indust- riell process.The chlorine-free gas can then be introduced into a final combustion chamber or alternatively used directly in an industrial process.
Uppfinningen kommer nu att beskrivas i anslutning till bi- fogade ritning, som visar ett exempel pá en anläggning för genomförande av processen enligt uppfinningen.The invention will now be described in connection with the accompanying drawing, which shows an example of a plant for carrying out the process according to the invention.
Anläggningen innefattar en reaktionskammare 1, infodrad med eldfast material. Det avfallmaterial som skall be- handlas, injiceras genom åtminstone en lans 2. Den er- forderliga energin tillföres enligt den föredragna ut- föringsformen medelst en i åtminstone en plasmagenerator 3 upphettad gas. Den gas som skall upphettas tillföres genom en ledning 4. Nämnda gas kan lämpligen utgöras av åtminstone en del av det oxidationsmedel som användes i processen. Ytterligare oxidationsmedel och/eller andra reaktanter tillföres genom lansar 5.The plant comprises a reaction chamber 1, lined with refractory material. The waste material to be treated is injected through at least one lance 2. The required energy is supplied according to the preferred embodiment by means of a gas heated in at least one plasma generator 3. The gas to be heated is supplied through a line 4. Said gas may suitably consist of at least a part of the oxidizing agent used in the process. Additional oxidizing agents and / or other reactants are added through lances 5.
Reaktionskammarens volym anpassas till övriga process- parametrar såsom gashastighet, energitäthet i plasma- gasen, mängd inmatat avfallsmaterial per tidsenhet, etc. så att erforderlig uppehàllstid för reaktionernas genom- förande uppkommer, dvs. i storleksordningen 0,5 - 1 sekunder.The volume of the reaction chamber is adapted to other process parameters such as gas velocity, energy density in the plasma gas, amount of waste material fed per unit time, etc. so that the required residence time for carrying out the reactions arises, ie. in the order of 0.5 - 1 seconds.
Från reaktionskammaren transporteras gasen i en ledning 6 till en tvätt 7, i vilken gasen kyles och befrias från alla klor innehållande föreningar.From the reaction chamber, the gas is transported in a line 6 to a wash 7, in which the gas is cooled and freed from all chlorine-containing compounds.
Den tvättade gasen transporteras sedan vidare genom en ledning 8 till en slutförbränningskammare 9, i vilken 453 863 .rn gasen förbrännes med luft tillförd genom en lans 10.The washed gas is then transported further through a line 8 to a final combustion chamber 9, in which the gas is combusted with air supplied through a lance 10.
Gasen kan givetvis användas direkt efter tvätten, om dess sammansättning och energiinnehåll gör den intressant för en industriell process eller liknande. el»The gas can of course be used immediately after washing, if its composition and energy content make it interesting for an industrial process or the like. el »
