Description
Føreliggande uppfinning avser ett satt for rening av avgaser från destruktionsanlaggningar for omhåndertagande av industri- och hushållsavfall från giftiga klorforeningar och/eller tyngre kolvåten samt en anlåggning for genomforande av sattet enligt uppfinningen. The present invention relates to a set for the purification of exhaust gases from destruction facilities for the management of industrial and domestic waste from toxic chlorine compounds and/or heavier hydrocarbons, as well as a facility for gene processing of the set according to the invention.
Konventionella sopforbranningsanlåggningar for hushålls-och industriavfall har visat sig avge icke ovåsentliga mångder hålsofarliga armen, bl.a. i form av klorforeningar, t.ex. dioxiner. Dessa foreningar bildas i for-brånningsrummet på grund av lokalt upptradande låga forbrånningstemperaturer. Dessa foreningar kan också bildas under nedkylning av avgaserna om dessa innehål- Conventional waste incineration plants for household and industrial waste have been shown to emit not insignificant amounts of health hazards, i.a. in the form of chlorine compounds, e.g. dioxins. These compounds are formed in the combustion chamber due to locally occurring low combustion temperatures. These associations can also form during cooling of the exhaust gases if these con-
ler klor och/eller klorvate.ler chlorine and/or chlorine vate.
For narvarande finns icke någon låmplig metod att saker-stålla att dylika klorforeningar ej bildas och det finns inte heller någon metod att avlagsna dem ur avgaserna från dessa typer av destruktionsanlaggningar. Currently, there is no suitable method to ensure that such chlorine compounds are not formed, and there is also no method to deposit them from the exhaust gases from these types of destruction facilities.
Ett andamål med foreliggande uppfinning år att åstadkomma ett satt for rening av avgaser från destruktionsanlaggningar for industri- och hushållsavfall som sakerståller att gaserna icke innehåller giftiga klorforeningar. One goal of the present invention is to provide a set for cleaning exhaust gases from destruction facilities for industrial and household waste which ensures that the gases do not contain toxic chlorine compounds.
Ett annat andamål med uppfinningen år att åstadkomma en reningsprocess som också eliminerar innehållet av tyngre kolvåten såsom tjåra och liknande. Another aim of the invention is to achieve a purification process which also eliminates the content of heavier hydrocarbons such as tar and the like.
Ytterligare ett åndamål med uppfinningen år att åstadkomma en anlåggning for genomforande av såttet enligt upp-f inningen. A further aim of the invention is to provide a facility for genome modification of the seed according to the invention.
Såttet enligt uppfinningen kånnetecknas av att i avgaserna forekommande klorforeningar nedbrytes genom bestrålning med UV-ljus i en spjålkningskammare och att i avgaserna forekommande tyngre kolvåten samtidigt spaltas genom tillforsel av extern, av forbrånning oberoende varmeenergi . The method according to the invention is made possible by the fact that chlorine compounds present in the exhaust gases are broken down by irradiation with UV light in a rinsing chamber and that the heavier hydrocarbons present in the exhaust gases are simultaneously split by the supply of external heat energy independent of combustion.
Enligt en utforingsform av uppfinningen åstadkommes UV--bestrålningen genom att en del av avgaserna ledes genom en i spjålkningskammaren alstrad elektrisk ljusbåge for upphettning av delar av gasstrommen till joniseringstemperatur under samtidigt hojande av gasens fysiska vårme inneha11. According to one embodiment of the invention, the UV-irradiation is achieved by passing part of the exhaust gases through an electric arc generated in the flushing chamber to heat parts of the gas volume to ionization temperature while simultaneously increasing the physical heat content of the gas11.
Enligt en annan utforingsform av uppfinningen åstadkommes UV-bestrålningen genom att avgaserna ledes genom en kammare i vilken infores en i en plasmagenerator till joniseringstemperatur upphettad gas. According to another embodiment of the invention, the UV radiation is achieved by passing the exhaust gases through a chamber into which gas heated to ionization temperature in a plasma generator is introduced.
Behandling med.plasmagas såvål genererad med s.k. over-ford ljusbåge, dvs. med en ljusbåge alstrad inne i kammaren, som med anvåndning av en plasmagenerator medfor uppvårmning av gaserna i kammaren, varvid det fysiska vårmeinnehållet i gaserna utnyttjas till att spjålka tyngre kolvåten som kan forekomma i avgaserna från ugnen, t.ex. tjåra. Treatment with plasma gas generated with so-called overhead arc, i.e. with an arc generated inside the chamber, as with the use of a plasma generator to heat the gases in the chamber, whereby the physical heat content in the gases is used to break down the heavier carbon dioxide that may occur in the exhaust gases from the furnace, e.g. e.g. the tar.
Avgaserna inledes låmpligen tangentiellt i spjålkningskammaren och bibringas en roterande fSrflyttningsrorelse, varigenom uppnås en jåmn bestrålning av hela den strom-mande gasmångden. The exhaust gases are introduced tangentially into the spalling chamber and are imparted with a rotating displacement movement, whereby an even irradiation of the entire flowing gas quantity is achieved.
For undvikande av återbildning av exempelvis dioxiner e;ller bildning av andra giftiga klor f oreningar kan enligt uppfinningen genomforas ytterligare ett processteg i det att de renade avgaserna efter kylning t.ex. genom vårmevåxling till 350 - 700°C inledes i en reaktor fylld med en låmplig acceptor for avlågsnande av klor och/eller klorvåte ur gasen liksom for kondensering av eventuella i gasen innehållna metallångor. Som acceptor anvåndes foretrådesvis brånd eller obrand kalk och/eller dolomit. To avoid the re-formation of, for example, dioxins or the formation of other toxic chlorine compounds, according to the invention, a further process step can be carried out in that the purified exhaust gases after cooling, e.g. through heat exchange to 350 - 700°C is introduced into a reactor filled with a suitable acceptor for removing chlorine and/or chlorine from the gas as well as for condensation of any metal vapors contained in the gas. As an acceptor, it is preferable to use slaked lime or burnt lime and/or dolomite.
I destruktionsanlaggningar som arbetar med syreunderskott, kan avgaserna dessutom i enlighet med foreliggande uppfinning efter bestrålning underkastas ett karburerings-steg, varvid gasen bringas att passera en reaktor fylld med fast styckeformig kolbårare, t.ex. koks, eventuellt med en reaktivitetshojande tillsats, t.ex. alkaliforening, varvid gasens fysiska varme utnyttjas for varmning av koksen till gasens temperatur och varvid kolet i koksen rea-gerar med syre, koldioxid och vattenånga i gasen und bildning av kolmonoxid och våtgas och varigenom gasens varme-varde hojs. In destruction plants that work with an acid deficit, the exhaust gases can also, in accordance with the present invention, after irradiation be subjected to a carburization step, whereby the gas is made to pass through a reactor filled with solid piece-shaped carbon carrier, e.g. coke, possibly with a reactivity-increasing additive, e.g. alkali fusion, where the physical heat of the gas is used to heat the coke to the temperature of the gas and where the carbon in the coke reacts with acid, carbon dioxide and water vapor in the gas and the formation of carbon monoxide and wet gas, whereby the heat of the gas increases.
Anlåggningen for genomforande av sattet enligt uppfinningen innefattar en ugn for destruktion av industri- The facility for genome preparation of the kit according to the invention comprises an oven for destruction of industrial
och hushållsavfall samt eventuella konventionella anordningar for vårmevåxling, rening och kylning, och kånnetecknas av en foretrådesvis vårmeisolerad spjålkningskammare innefattande en kålla for UV-bestrålning och samtidig vårmeenergitillforsel. and household waste as well as any conventional devices for heat exchange, purification and cooling, and can be characterized by a preferably heat-insulated splashing chamber including a bowl for UV radiation and simultaneous heat energy supply.
Spjålkningskammaren utformas foretrådesvis som en vårmeisolerad reaktor i vilken avgaserna leds in tangentiellt och ror sig genom kammaren i en roterande rorelse långs kammarens vågg til\ det i dess motsatta ånde belågna ut-loppet. The rinsing chamber is preferably designed as a heat-insulated reactor in which the exhaust gases are fed in tangentially and move through the chamber in a rotating motion along the wall of the chamber to the outlet located on the opposite side.
Enligt en utforingsform av anlåggningen enligt uppfinningen utgores kållan for UV-bestrålning och varmeenergi- tillforsel av två i kammaren inforda elektroder mellan vilka alstras en elektrisk ljusbåge, inne i kammaren, genom vilken en del av avgasstrommen bringas att passera. According to an embodiment of the installation according to the invention, the tube for UV radiation and heat energy supply is made of two electrodes in the chamber between which an electric arc is generated, inside the chamber, through which part of the exhaust gas flow is made to pass.
Enligt ett alternativt utforande av anlåggningen enligt uppfinningen utgores kållan for UV-bestrålning och vårmeenergitillforsel av minst en plasmagenerator anordnad i omedelbar anslutning till spjålkningskammaren och i vilken en gasstrom upphettas till joniseringstemperatur i en elektrisk ljusbåge, alstrad mellan två i plasma-generatorn ingående elektroder och vilken joniserade gas sedan infores i kammaren. According to an alternative embodiment of the installation according to the invention, the tube for UV radiation and heat energy supply is made of at least one plasma generator arranged in immediate connection to the spalling chamber and in which a gas stream is heated to ionization temperature in an electric arc, generated between two electrodes included in the plasma generator and which ionized gas is introduced into the chamber.
Enligt en ytterligare utforingsform av uppfinningen innefattar anlåggningen ett omedelbart efter spjålkningskammaren anordnat, koksfyllt karbureringsschakt. According to a further embodiment of the invention, the installation includes a coke-filled carburizing shaft arranged immediately after the spalling chamber.
Enligt ytterligare en utforingsform av uppfinningen innefattar anlåggningen enligt uppfinningen en reaktor fylld med en låmplig acceptor for i gasen forekommande klor och/eller klorvåte. Acceptorn utgores foretrådesvis av brånd eller obrånd kalk och/eller dolomit. Reaktorn utgores foretrådesvis av ett vertikalt schakt med till-forselanordningar for acceptor vid dess topp samt av-tappningsorgan for avlågsnande av upptagna produkter. According to a further embodiment of the invention, the plant according to the invention comprises a reactor filled with a suitable acceptor for the chlorine and/or wet chlorine present in the gas. The acceptor is preferably made of burnt or unburnt lime and/or dolomite. The reactor preferably consists of a vertical shaft with supply devices for the acceptor at its top as well as draining means for draining absorbed products.
Ytterligare fordelar och kånnetecken hos uppfinningen kommer att framgå av nedanstående detaljerade beskriv-ning i anslutning till bifogade ritningar, på vilka Further advantages and features of the invention will be apparent from the detailed description below in connection with the attached drawings, on which

fig. 4 visar en schematisk bild av en spjålkningskammare som arbetar efter en alternativ utforingsform av uppfinningen i kombination med ett karbureringsschakt. fig. 4 shows a schematic view of a rinsing chamber that works according to an alternative embodiment of the invention in combination with a carburizing shaft.
Den i figur 1 schematiskt visade anlåggningen innefattar en sopforbrånningsugn 1 som arbetar med syredverskott, dvs. ren forbrånning. Avgaserna ledes till en spjålkningskammare2, vilken kommer att beskrivas nårmare nedan, i vilken i gasen forekommande hålsofarliga klorf6-reningar spjalkas genom UV-bestrålning. Tyngre kolvåten sonderdelas genom den samtidiga varmeenergitillforseln. The installation shown schematically in figure 1 comprises a waste incineration furnace 1 which works with acid residues, i.e. pure combustion. The exhaust gases are led to a splitting chamber2, which will be described in more detail below, in which the harmful chlorine compounds in the gas are split by UV radiation. Heavier hydrocarbons are probed through the simultaneous supply of heat energy.
Från spjalkningskammaren ledes de renade avgaserna, eventuellt efter en klorrening som beskrivs nårmare i anslutning till figur 2, låmpligen vidare till en vårmevåxlare 3, en renings- och kylanordning 4 samt avledes från en skor-sten 5, representerande konventionell teknik som inte kommer att avhandlas nårmare hår. From the splitting chamber, the purified exhaust gases are led, possibly after a chlorine purification that is described further in connection with figure 2, possibly further to a heat exchanger 3, a purification and cooling device 4 and are diverted from a chimney 5, representing conventional technology that will not be discussed closer hair.
Den i figur 2 schematiskt visade anlåggningen innefattar en destruktionsanlåggning 10 som utnyttjar syreunderskott och sålunda kan anvåndas for produktion av brånn-bara gaser. Avgaserna ledes från ugnen till en spjålk-ningskammre 11 av samma slag som antytts ovan och som kommer att beskrivas nårmare nedan. Gasen från spjålkningskammaren 11 ledes in i ett omedelbart dårefter anordnat karbureringsschakt 12, i vilket gasens vårme- vårde okas genom utnyttjande av gasens fysiska vårmeinnehåll. The installation shown schematically in Figure 2 comprises a destruction installation 10 which utilizes an acid deficit and can thus be used for the production of combustible gases. The exhaust gases are led from the oven to a splashing chamber 11 of the same type as indicated above and which will be described further below. The gas from the spalling chamber 11 is led into a carburizing shaft 12 arranged immediately afterwards, in which the heat of the gas is maintained by utilizing the physical heat content of the gas.
Från karbureringsschaktet ledes gasen over en kylare eller vårmevåxlare 13, i vilken temperaturen sankes till en temperatur av ca 350 - 700°C, till en klorreningsen-het 14, i vilken klor och/eller klorvåte i gaserna avlågs-nas medelst en acceptor i form av brand eller obrånd kalk och/eller dolomit. From the carburizing shaft, the gas is led 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 chlorine water in the gases is removed by means of an acceptor in the form of burnt or burnt lime and/or dolomite.
Den sålunda renade och kvalitetsforbattrade gasen kan sedan bringas att passera konventionella behandlingsenheter eller eventuellt avdragas till forbrånning eller annat utnyttjande. The thus purified and quality-improved gas can then be made to pass through conventional treatment units or possibly diverted to incineration or other utilization.
I figur 3 visas en spjalkningskammare 30 anordnad i anslutning till ett karbureringsschakt 31. Det skall ob-serveras att spjalkningskammaren i den i figur 1 visade anlåggningen arbetar separat och att den inte behover åtfoljas av ett karbureringsschakt. Detsamma gåiler gi-vetvis for det utforande av spjålkningskammaren som visas i figur 4. Figure 3 shows a splitting chamber 30 arranged in connection with a carburizing shaft 31. It must be observed that the splitting chamber in the installation shown in Figure 1 works separately and that it does not need to be followed by a carburizing shaft. The same obviously applies to the front of the spalling chamber shown in figure 4.
I det visade utforandet i figur 3 år spjålkningskammaren enligt uppfinningen utformad som en reaktor med ett tangentiellt inlopp 32 for avgaserna från forbrånningsugnen. Kammaren inrymmer en bottenelektrod 33 samt en ringformad elektrod 34 mellan vilka alstras en elektrisk ljusbåge 35. Vid passagen genom ljusbågen kommer en mindre del av avgaserna att uppnå joniseringstemperatur och dårmed åven avge UV-strålning, och genom att avgaserna bibringats en roterande forflyttningsrorelse erhålles en jåmn, fullstån-dig bestrålning av avgaserna. In the embodiment shown in Figure 3, the rinsing chamber according to the invention is designed as a reactor with one tangential inlet 32 for the exhaust gases from the incinerator. The chamber contains a bottom electrode 33 and an annular electrode 34 between which an electric arc 35 is generated. During the passage through the arc, a smaller part of the exhaust gases will reach ionization temperature and thereby also emit UV radiation, and by imparting a rotating movement to the exhaust gases, an even , complete irradiation of the exhaust gases.
I spjålkningskammaren Skas vidare gasens fysiska vårmeinnehåll genom den tillforda elektriska energin, vilket vårmeinnehåll sedan kan utnyttjas i det efterf61jande karbureringssteget. Karbureringsschaktet 31 innefattar en kokstillforselanordning 36 i toppen och ett utlopp 37 In the flushing chamber, the physical heat content of the gas is further reduced by the supplied electrical energy, which heat content can then be used in the following carburizing step. The carburizing shaft 31 comprises a coking supply device 36 at the top and an outlet 37
for restprodukter i botten. Avgaserna infores vid reaktorns botten och avdrages genom ett ovre gasutlopp 38. for residual products in the bottom. The exhaust gases enter at the bottom of the reactor and are removed through an upper gas outlet 38.
Koksfyllningen i reaktorn uppvarmes av gasens fysiska vårmeinnehåll till gasens temeratur och syre, koldioxid och vattenånga omsåttes med kolet i koksen till koloxid och våtgas. Hårefter kan vid behov gasen renas från svavel på konventionellt sått. The coke filling in the reactor is heated by the gas's physical heat content to the gas's temperature and acid, carbon dioxide and water vapor are mixed with the carbon in the coke to carbon dioxide and wet gas. Afterwards, if necessary, the gas can be purified from sulfur in the conventional way.
Efter nåmnda eventuella svavelrening kyles eller vårme-våxlas gasen till ca 350 - 700°C och ledes genom en låmplig acceptor for klor och klorvåte i gasen, låmpligen brånd eller obrånd kalk och/eller dolomit. Hårvid anvåndes med fordel en vertikal reaktor fylld med acceptorn. After any sulfur removal, the gas is cooled or heated to approx. 350 - 700°C and passed through a suitable acceptor for chlorine and chlorine in the gas, preferably burnt or unburnt lime and/or dolomite. A vertical reactor filled with acceptor is advantageously used.
Figur 4 visar som i figur 3 en spjålkningskammare 40 anordnad i omedelbar anslutning till ett karbureringsschakt 41. En gas, låmpligen en enatomig gas, tillfores en plasmagenerator 42 och upphettas i en dåri alstrad elektrisk ljusbåge till joniseringstemperatur. Den sålunda upp-hettade gasen infores i spjålkningskammaren 40 vid 43 under det att avgasen inledes tangentiellt genom inloppet 44 och hårvid bestrålas av den av plasmagasen avgivna UV-strål-ningen. Samtidigt varms avgaserna åtminstone något av den heta plasmagasen, vilken vårme sedan kan utnyttjas enligt tidigare i karbureringsschaktet. Den vårmemångd som tillfores på detta sått kan i och for sig också regleras. Figure 4 shows, as in Figure 3, a spalling chamber 40 arranged in immediate connection to a carburizing shaft 41. A gas, presumably a monatomic gas, is fed to a plasma generator 42 and heated in an electric arc generated therein to ionization temperature. The thus heated gas is introduced into the splash chamber 40 at 43 while the exhaust gas is introduced tangentially through the inlet 44 and is irradiated by the UV radiation given off by the plasma gas. At the same time, the exhaust gases are heated at least somewhat by 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 also be regulated in and of itself.
