The acceptor is preferably burnt or quicklime and / or dolomite. The reactor preferably consists of a vertical shaft with supply devices for acceptor at its top and drainage means for removing absorbed products.
Ytterligare fördelar och kännetecken hos uppfinningen kommer att framgå av nedanstående detaljerade beskriv- ning i anslutning till bifogade ritningar, pâ vilka fig. 1 visar en schematisk bild av en avfallsdestruk- tionsanläggning enligt uppfinningen, fig. 2 visar en schematisk bild av en alternativ utfö- ringsform av en avfallsdestruktionsanläggning enligt uppfinningen, 10 15 20 25 452 255 fig. 3 visar en schematisk bild av en spjälkningskam- mare som arbetar enligt en utföringsform av upp- finningen i kombination med ett karburerings- schakt, och fig. 4 visar en schematisk bild av en spjälkningskam- mare som arbetar efter en alternativ utförings- form av uppfinningen i kombination med ett kar- bureringsschakt.Further advantages and features of the invention will appear from the following detailed description in connection with the accompanying drawings, in which Fig. 1 shows a schematic view of a waste disposal plant according to the invention, Fig. 2 shows a schematic view of an alternative embodiment. Fig. 3 shows a schematic view of a cleavage chamber operating according to an embodiment of the invention in combination with a carburizing shaft, and Fig. 4 shows a schematic view of a waste destruction plant according to the invention. of a cleavage chamber operating according to an alternative embodiment of the invention in combination with a carburizing shaft.
Den i figur 1 schematiskt visade anläggningen innefattar en sopförbränningsugn 1 som arbetar med syreöverskott, dvs. ren förbränning. Avgaserna ledes till en spjälk- ningskammarez, vilken kommer att beskrivas närmare ne- dan, i vilken i gasen förekommande hälsofarliga klorfö- reningar spjälkas genom UV-bestrålning. Tyngre kolväten sönderdelas genom den samtidiga värmeenergitillförseln.The plant schematically shown in figure 1 comprises a waste incinerator 1 which works with excess oxygen, i.e. clean combustion. The exhaust gases are led to a decomposition chamber, which will be described in more detail below, in which hazardous chlorine compounds present in the gas are decomposed by UV irradiation. Heavier hydrocarbons are decomposed by the simultaneous heat energy supply.
Från spjälkningskammaren ledes de renade avgaserna, even- tuellt efter en klorrening som beskrivs närmare i anslut- ning till figur 2, lämpligen vidare till en värmeväxlare 3, en renings- och kylanordning 4 samt avledes från en skor- - sten 5, representerande konventionell teknik som inte kom- mer att avhandlas närmare här.From the decomposition chamber, the purified exhaust gases, possibly after a chlorine purification described in more detail in connection with Figure 2, are suitably passed on to a heat exchanger 3, a purification and cooling device 4 and diverted from a chimney 5, representing conventional technology. which will not be discussed in more detail here.
Den i figur 2 schematiskt visade anläggningen innefattar en destruktionsanläggning 10 som utnyttjar syreunder- skott och sålunda kan användas för produktion av bränn- bara gaser. Avgaserna ledes från ugnen till en spjälk- ningskammre 11 av samma slag som antytts ovan och som kommer att beskrivas närmare nedan. Gasen från spjälk- ningskammaren 11 ledes in i ett omedelbart därefter an- ordnat karbureringsschakt 12, i vilket gasens värme- 10 15 20 25 452 255 värde ökas genom utnyttjande av gasens fysiska värme- innehåll.The plant shown diagrammatically in Figure 2 comprises a destruction plant 10 which utilizes oxygen deficiencies and can thus be used for the production of combustible gases. The exhaust gases are led from the furnace to a decomposition chamber 11 of the same type as indicated above and which will be described in more detail below. The gas from the decomposition chamber 11 is led into an immediately afterwards arranged carburizing shaft 12, in which the heat value of the gas is increased by utilizing the physical heat content of the gas.
Från karbureringsschaktet ledes gasen över en kylare eller värmeväxlare 13, i vilken temperaturen sänkes till en temperatur av ca 350 - 700°C, till en klorreningsen- het 14, i vilken klor och/eller klorväte i gaserna avlägs- nas medelst en acceptor i form av bränd eller obränd ¿ kalk och/eller dolomit. l Den sålunda renade och kvalitetsförbättrade gasen kan se- dan bringas att passera konventionella behandlingsenheter eller eventuellt avdragas till förbränning eller annat utnyttjande.From the carburizing shaft the gas is passed over a cooler or heat exchanger 13, in which the temperature is lowered to a temperature of about 350 - 700 ° C, to a chlorine purification unit 14, in which chlorine and / or hydrogen chloride in the gases are removed by means of an acceptor in the form of burnt or unburned ¿lime and / or dolomite. The gas thus purified and quality-improved can then be passed through conventional treatment units or possibly deducted for combustion or other use.
I figur 3 visas en spjälkningskammare 30 anordnad i an- slutning till ett karbureringsschakt 31. Det skall ob- serveras att spjälkningskammaren i den i figur 1 visade anläggningen arbetar separat och att den inte behöver âtföljas av ett karbureringsschakt. Detsamma gäller gi- vetvis för det utförande av spjälkningskammaren som vi- sas i figur 4. x u..Figure 3 shows a splitting chamber 30 arranged in connection with a carburizing shaft 31. It should be noted that the splitting chamber in the plant shown in figure 1 operates separately and that it does not have to be accompanied by a carburizing shaft. The same applies, of course, to the design of the cleavage chamber shown in Figure 4. x u ..
I det visade utförandet i figur 3 är spjälkningskammaren enligt uppfinningen utformad som en reaktor med ett tan- gentiellt inlopp 32 för avgaserna från förbränningsugnen.In the embodiment shown in Figure 3, the decomposition chamber according to the invention is designed as a reactor with a tangential inlet 32 for the exhaust gases from the incinerator.
Kammaren inrymmer en bottenelektrod 33 samt en ringformad elektrod 34 mellan vilka alstras en elektrisk ljusbåge 35.The chamber houses a bottom electrode 33 and an annular electrode 34 between which an electric arc 35 is generated.
Vid passagen genom ljusbàgen kommer en mindre del av av- gaserna att uppnå joniseringstemperatur och därmed även avge UV-strålning, och genom att avgaserna bibringats en å roterande förflyttningsrörelse erhålles en jämn, fullstän- dig bestrâlning av avgaserna. av. 10 15 20 25 452 255 I spjälkningskammaren ökas vidare gasens fysiska värme- innehåll genom den tillförda elektriska energin, vilket värmeinnehåll sedan kan utnyttjas i det efterföljande karbureringssteget. Karbureringsschaktet 31 innefattar en kokstillförselanordning 36 i toppen och ett utlopp 37 för restprodukter i botten. Avgaserna_införesvidreaktorns botten och avdrages genom ett övre gasutlopp 38.During the passage through the arc, a small part of the exhaust gases will reach ionization temperature and thus also emit UV radiation, and by giving the exhaust gases a rotating movement movement, an even, complete irradiation of the exhaust gases is obtained. of. 10 15 20 25 452 255 In the digestion chamber, the physical heat content of the gas is further increased by the supplied electrical energy, which heat content can then be used in the subsequent carburization step. The carburizing shaft 31 comprises a coke supply device 36 at the top and an outlet 37 for residual products at the bottom. The exhaust gases are introduced into the bottom of the reactor and drawn off through an upper gas outlet 38.
Koksfyllningen i reaktorn uppvärmes av gasens fysiska vär- meinnehåll till gasens temeratur och syre, koldioxid och vattenånga omsättes med kolet i koksen till koloxid och vätgas. Härefter kan vid behov gasen renas från svavel på konventionellt sätt.The coke filling in the reactor is heated by the physical heat content of the gas to the temperature of the gas and oxygen, carbon dioxide and water vapor are reacted with the carbon in the coke to carbon oxide and hydrogen gas. Thereafter, if necessary, the gas can be purified from sulfur in a conventional manner.
Efter nämnda eventuella svavelrening kyles eller värme- växlas gasen till ca 350 - 700°C och ledes genom en lämp- lig acceptor för klor och klorväte i gasen, lämpligen fi* bränd eller obränd kalk och/eller dolomit. Härvid användes med fördel en vertikal reaktor fylld med acceptorn.After the said sulfur purification, the gas is cooled or heat exchanged to about 350 - 700 ° C and passed through a suitable acceptor for chlorine and hydrogen chloride in the gas, suitably burnt or unburned lime and / or dolomite. In this case, a vertical reactor filled with the acceptor is advantageously used.
Figur 4 visar som i figur 3 en spjälkningskammare 40 an- ordnad i omedelbar anslutning till ett karbureringsschakt 41.Figure 4 shows, as in Figure 3, a splitting chamber 40 arranged in immediate connection with a carburizing shaft 41.
En gas, lämpligen en enatomig gas, tillföres en plasma- generator 42 och upphettas i en däri alstrad elektrisk ljusbåge till joniseringstemperatur. Den sålunda upp- hettade gasen införes i spjälkningskammaren 40 vid 43 under det att avgasen inledes tangentiellt genom inloppet 44 och härvid bestrålas av den av plasmagasen avgivna UV-strâl- ningen. Samtidigt värms avgaserna åtminstone något av den heta plasmagasen, vilken värme sedan kan utnyttjas enligt tidigare i karbureringsschaktet. Den värmemängd som till- föres på detta sätt kan i och för sig också regleras.A gas, preferably an enatomic gas, is fed to a plasma generator 42 and heated in an electric arc generated therein to ionization temperature. The gas thus heated is introduced into the decomposition chamber 40 at 43 while the exhaust gas is introduced tangentially through the inlet 44 and is thereby irradiated by the UV radiation emitted by the plasma gas. At the same time, the exhaust gases are heated by at least some of the hot plasma gas, which heat can then be used as before in the carburizing shaft. The amount of heat supplied in this way can in itself also be regulated.
