Description

i DK 168245 B1in DK 168245 B1

Opfindelsen angår en fremgangsmåde til forbrænding af fast og eventuelt flydende affald i et anlæg, hvor der anvendes en roterovn, som i affaldets fremføringsretning er anbragt 5 efter en forbrændingssektion med trapperiste.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for combustion of solid and possibly liquid waste in a plant using a rotary kiln, which in the direction of conveyance of the waste is arranged 5 after a combustion section with stair grate.

Med de stadigt større affaldsmængder og de stadigt større miljømæssige krav, der stilles til forbrændingen af affaldet, dannes stadigt større mængder skadelige restprodukter som følge af røgrensning.With the ever-increasing quantities of waste and the ever-increasing environmental demands placed on the incineration of the waste, ever-increasing quantities of harmful residues are generated as a result of smoke cleaning.

10 I de i dag kendte affaldsforbrændingsanlæg holdes forbrændingstemperaturen under 1100°C, f.eks. omkring 875°C, for at undgå dannelse af flydende slagge ved ristesektionens sidevægge og i roterovnen, idet denne har tendens til at størkne ved ovnsiderne og blokere roterovnen ved 15 bortførselsenden.In today's known waste incineration plants, the incineration temperature is kept below 1100 ° C, e.g. about 875 ° C, to avoid the formation of liquid slag at the side walls of the grate section and in the rotary kiln as it tends to solidify at the oven sides and block the rotary kiln at the removal end.

Anlæggene er indrettet og konstrueret til, at slaggen og asken udtrækkes som en henholdsvis tør eller befugtet inhomogen blanding i op til 3 forskellige uddoseringssy-stemer.The systems are designed and constructed to extract the slag and ash as a dry or wetted inhomogeneous mixture, respectively, in up to 3 different dosing systems.

20 Således fås kedelaske fra kedelanlægget, der f.eks. er af bankeværkstypen, og flyveaske fra et elektrofilter. Endvi- dere foretages røgrensning ved tilsætning af f.eks. kalk, hvorefter røggassen passerer et filter eller et røggas-vaskeanlæg, hvor et restprodukt skilles fra.Thus, boiler ash is obtained from the boiler plant which e.g. is of the knocking type, and fly ash from an electro filter. Furthermore, smoke cleaning is carried out by adding e.g. lime, after which the flue gas passes through a filter or a flue gas washing system where a residual product is separated.

25 Desuden falder "småt affald" gennem risten, og sådant ristegennemfald føres til et slaggeudtag. Det kræves imidlertid, at mindre end 3% af slaggen er uforbrændt.25 In addition, "small debris" falls through the grate and such grate penetration is led to a slag removal. However, less than 3% of the slag is required to be unburned.

Disse kendte anlæg har naturligvis de ulemper, at de i slaggen, i flyveasken og i restprodukterne fra røggas-30 vaskeanlægget vedhæftende salte og tungmetaller er udvaskbare, og nogle tungmetaller fordamper under processen.Of course, these known plants have the disadvantages of being washable in the slag, in the fly ash and in the residual products of the flue gas washing plant, and some heavy metals evaporate during the process.

DK 168245 B1 2DK 168245 B1 2

Disse produkter må derfor deponeres sikkert, f.eks. på kontrollerede lossepladser, hvorved der fremkommer et percolat, som belaster miljøet betydeligt, eller i salt-5 miner.These products must therefore be safely deposited, e.g. at controlled landfills, resulting in a percolate that significantly impacts the environment, or in salt-5 mines.

Fra europæisk patentansøgning nr. 330.872 kendes et anlæg, hvor farlige affaldsstoffer indkapsles i flydende affald.European Patent Application No. 330,872 discloses a plant in which hazardous waste is encapsulated in liquid waste.

Ved denne kendte fremgangsmåde tilføres den til smeltningen af affaldet nødvendige varmeenergi fra en separat.In this known process, the heat energy required for the waste is supplied separately from the waste.

10 brænder og indkapslingen sker på en skråtstillet trapperist. Der er ingen efterkoblet roterovn og ingen tilbageføring af askeprodukter til roterovnens tilførselsende.10 burns and the enclosure takes place on an inclined staircase. There is no after-coupled rotary kiln and no return of ash products to the rotary kiln supply end.

Der anvendes forholdsvis megen energi til smeltningen og indkapslingen foregår uden omrøring, men blot med neddump-15 ning af aske i den kun delvis smeltede affaldsmasse.Relatively much energy is used for the melting and the encapsulation takes place without stirring, but only with the dumping of ash into the only partially melted waste mass.

Fra dansk fremlæggelsesskrift nr. 149.317 er det ligeledes kendt at indkapsle farlige affaldsstoffer ved et anlæg til fremstilling af cementklinker. Ved dette anlæg anvendes der ingen trapperist til forbrænding af affaldet, 20 og der er ingen tilbageføring af askeprodukter til roterovnens tilførselsende, hvorved der fra det samlede anlæg afgives en forholdsvis stor mængde ikke-indkapslede affaldsstoffer.It is also known from Danish submission no. 149,317 to encapsulate hazardous waste at a cement clinker plant. At this plant, no stair grate is used to incinerate the waste, 20 and there is no return of ash products to the supply end of the rotary kiln, whereby a relatively large amount of non-encapsulated waste is released from the total plant.

Opfindelsen har til formål at uskadeliggøre de ved 25 forbrændingen af fast og/eller flydende affald fremkomne slagger, flyveaske og andre skadelige restprodukter.The invention aims to harm the slag, fly ash and other harmful residues resulting from the combustion of solid and / or liquid waste.

Dette formål opnås ved fremgangsmåden ifølge krav 1, idet stofferne indkapsles i den relativt varme, flydende slagge ved passage igennem roterovnen. Herved bliver produktet 30 fra affaldsforbrændingen en uskadelig, glassificeret slagge, der ikke afgiver skadelige stoffer, såsom tungmetaller, og derfor kan deponeres uden problemer.This object is achieved by the method of claim 1, wherein the substances are encapsulated in the relatively hot liquid slag by passage through the rotary kiln. Hereby, the product 30 from the waste incineration becomes a harmless, glassy slag which does not emit harmful substances such as heavy metals and therefore can be safely deposited.

DK 168245 B1 3DK 168245 B1 3

Fremgangsmåden ifølge opfindelsen er således ejendommelig ved, at a) det faste affald forbrændes delvis på trapperistene og 5 afgives til roterovnen ved en så høj temperatur, at der i roterovnen dannes en flydende slagge, b) at der eventuelt tilsættes flydende affald til det på trapperistene under forbrænding værende affald, og c) at askeprodukterne fra forbrændingen, såsom riste- 10 gennemfald, kedelaske, flyveaske og restprodukter fra røgrensning, opsamles og tilbageføres til roterovnens tilførselsende, hvor disse produkter smeltes sammen med den flydende slagge.The process according to the invention is characterized in that a) the solid waste is partially incinerated on the stair grate and 5 is discharged to the rotary kiln at a temperature so high that a liquid slag is formed in the rotary kiln, b) if any liquid waste is added to it on the stair grate. and (c) the ash products from the combustion, such as grate, boiler ash, fly ash and residue from smoke purification, are collected and returned to the feed end of the rotary kiln where these products are fused with the liquid slag.

Fremgangsmåden ifølge opfindelsen kan udføres i anlægget 15 ifølge opfindelsen, der er ejendommeligt ved, at der er tilvejebragt et indfødningsaggregat som ved roterovnens tilførselsende doserer opsamlede askeprodukter fra forbrændingsanlægget i en kontinuerlig proces for sammensmeltning af disse stoffer med den flydende slagge til et 20 glasagtigt produkt, der afgives ved roterovnens bortførselsende.The process according to the invention can be carried out in the plant 15 according to the invention, characterized in that there is provided a feeding assembly which at the end of the rotary furnace doses collected ash products from the combustion plant in a continuous process for fusing these substances with the liquid slag to a glassy product. which is delivered at the discharge end of the rotary kiln.

Denne affaldsforbrænding kan foregå i et anlæg, hvor affaldstyper, som indfødes, eventuelt gennem flere indfødningssystemer, udtørres, antændes og forbrændes. Det 25 faste affald forbrændes til en ikke færdig udbrændt slagge, som derefter nedstyrtes i en med ristesektionen sammenbygget roterovn i direkte linie, hvor denne slaggeblanding og de separat indfødte restprodukter fra røggasrensningsanlægget sammensmeltes til en glasagtig masse.* 30 Roterovnens rotation fremmer udbrænding og sammensmeltning af massen til et homogent materiale.This waste incineration can take place in a plant where waste types that are indigenous, possibly through multiple feeding systems, are dried out, ignited and incinerated. The 25 solid waste is incinerated into an incompletely incinerated slag, which is then disposed of in a direct line rotary kiln integrated with the grate section, where this slag mixture and the separately native residual products from the flue gas purification plant are fused to a glassy mass. * 30 The rotary kiln's rotation promotes combustion and fusion. the mass of a homogeneous material.

Slaggen smeltes fortrinsvis ved en temperatur på ca. 1100°C eller derover. Herved opnås, at slaggen ikke størkner i roterovnen.The slag is preferably melted at a temperature of approx. 1100 ° C or higher. This ensures that the slag does not solidify in the rotary kiln.

DK 168245 B1 4DK 168245 B1 4

Temperaturen i risteovnrummet og roterovnen styres fortrinsvis ved åbning og lukning af et spjæld i en by-pass kanal mellem risteovnrum og røgkanal.The temperature of the toaster oven and rotary oven is preferably controlled by opening and closing a damper in a by-pass duct between the oven and smoke duct.

5 Energikilden til smeltningen er fortrinsvis selve det tilførte affald.5 The energy source for the melting is preferably the waste itself.

Endvidere er der fortrinsvis anbragt en brænder ved roterovnens bortførselsende for om nødvendigt at sikre opretholdelse af en så høj temperatur, at slaggen ikke størk-10 ner i roterovnen. Herved ud jævnes varierende brændværdier af affaldet, og der sikres et kontinuerligt smelteudtræk.Furthermore, a burner is preferably provided at the discharge end of the rotary kiln to ensure, if necessary, the maintenance of such a high temperature that the slag does not solidify in the rotary kiln. In this way, varying calorific values of the waste are leveled and a continuous melt extraction is ensured.

Fortrinsvis opsamles restprodukterne i en opsamlingsbeholder anbragt foran indfødningsaggregatet regnet i restprodukternes fremføringsretning.Preferably, the residual products are collected in a collection container located in front of the feed assembly calculated in the direction of feed of the residual products.

15 Dette system har den fordel, at der tilsættes mindst mulig luft, og samtidig udnyttes den ved forbrændingsprocessen tilførte ilt maksimalt. Den derved til dels fremkomne reducerende atmosfære nedsætter smeltepunktet for diverse indifferente materialer, uden at der skal tilsættes reduk-20 tionsmidler.15 This system has the advantage of adding as little air as possible and at the same time utilizing the oxygen supplied during the combustion process to the maximum. The resulting reducing atmosphere, in part, decreases the melting point of various inert materials without reducing agents.

Ifølge opfindelsen kan den om en skråt nedadhældende akse roterende ovn have en konisk tilspidset eller indsnævret udgangsende.According to the invention, it can have a tapered or narrowed exit end about a inclined downwardly rotating furnace.

Herved opnås, at den flydende slagge forbliver i en lomme 25 ved roterovnens nederste del, indtil en fuldstænding forgi asning er opnået.This ensures that the liquid slag remains in a pocket 25 at the bottom of the rotary kiln until complete freezing is achieved.

Opfindelsen skal i det følgende forklares nærmere med henvisning til tegningen, på hvilken fig. 1 er et principdiagram, der viser funktionen af 30 anlægget ifølge opfindelsen, DK 168245 B1 5 fig. 2 viser et skematisk tværsnit gennem et i overensstemmelse med opfindelsen udformet anlæg, og fig. 3 viser et snit efter linie III-III i fig. 2 med 5 placering af indfødning for restprodukter.The invention will now be explained in more detail with reference to the drawing, in which 1 is a principle diagram showing the operation of the system according to the invention; FIG. 2 shows a schematic cross-section through a system formed in accordance with the invention; and FIG. 3 shows a section along line III-III in FIG. 2 with 5 placement of native for residual products.

10 Det til forbrænding bestemte affald 21, der fortrinsvis består af husholdningsaffald, bark, industriaffald, syge-husaffald og til dels kemisk affald i en forholdsvis inhomogen sammenblanding, tilføres igennem påfyldningstragten 20 og indfødningsskakten 8 til venstre i fig. 2.10 The waste 21 intended for incineration, which preferably consists of household waste, bark, industrial waste, hospital waste and partly chemical waste in a relatively inhomogeneous mixture, is fed through the filling hopper 20 and the feeding shaft 8 to the left in FIG. 2nd

15 Det indfødte materiale fordeles på riste 9, 10, 11, og dertil føres også eventuelt flydende affald, og nedefra tilføres forbrændingsluft 31.15 The indigenous material is distributed on grate 9, 10, 11, to which also any liquid waste is fed, and from below combustion air is supplied 31.

Ristegennemfald, dvs. småstykker af affald, der kan indeholde uforbrændt materiale falder gennem ristene 9, 10, 20 11, føres af et transportbånd 17 og en transportør 7 til en opsamlingsbeholder 4.Grating penetration, ie. scraps of debris that may contain unburned material fall through grates 9, 10, 20 11 are passed by a conveyor belt 17 and a conveyor 7 to a collection container 4.

Den ved forbrændingen i ristesektionen dannede uudbrændte slagge udtømmes på kendt måde i roterovnen 2. Ved overgang 12 fra ristesektionen 1 til roterovnen 2 indfødes de 25 i mellemsiloen 4 opsamlede restprodukter gennem en doseringssnegl 13, og restprodukterne sammenblandes og udbrændes til en smeltende masse i roterovnen 2.The unburned slag formed during combustion in the grate section is discharged in a known manner in the rotary kiln 2. At transition 12 from the grate section 1 to the rotary kiln 2, the 25 residues collected in the middle silo 4 are fed through a metering screw 13 and the residual products are mixed and burned to a melting mass in the rotary kiln 2. .

Roterovnen 2 kan have konisk tilspidsede ender, som sikrer tilbageholdelse af den flydende slagge.The rotary kiln 2 may have tapered tapered ends which ensure retention of the liquid slag.

Ved roterovnens 2's bortførselsende 15 ses placeringen af brænderen 3, fortrinsvis et oxygen/gas-brænder-system, som sørger for en kontinuerlig temperaturkontrol ved slag-5 geudløb. Fra slaggeudløbet 15 føres slaggen bort via et transportbånd 22.At the abutment end 15 of the rotary kiln 2, the location of the burner 3, preferably an oxygen / gas burner system, is provided which provides a continuous temperature control at the slag outlet. From the slag outlet 15, the slag is conveyed via a conveyor belt 22.

Røggasserne føres fra roterovnen 2 gennem et efterforbræn-dingskammer 5 til et kedelanlæg 6. Her udskilles kedelaske 28 i en bankeværkskedel, og der udskilles flyveaske 29 ved 10 hjælp af et elektrofilter 23. Kedelasken 28 og flyveasken 29 føres af et transportbånd 18 og transportøren 7 til opsamlingsbeholderen 4.The flue gases are passed from the rotary furnace 2 through a post-combustion chamber 5 to a boiler system 6. Here, boiler ash 28 is separated into a knock-off boiler, and fly ash 29 is separated by an electric filter 23. The boiler ash 28 and the fly ash 29 are passed by a conveyor belt 18 and the conveyor 7 to the collection container 4.

Efter elektrofilteret 23 passerer røggasserne ind i reaktoren 24 i et røggasrenseanlæg, hvor der tilsættes kalk 15 25. Reaktionsprodukterne herfra føres til et filter 26, hvor et restprodukt 30 skilles fra. Dette restprodukt 30. føres af transportbånd 19, 32 til transportøren 7 og videre til opsamlingsbeholderen 4, medens de for restproduktet 30 befriede, uskadelige røggasser bortledes gennem 20 en skorsten 27.After the electro filter 23, the flue gases pass into the reactor 24 in a flue gas purifier, where lime 15 is added. The reaction products are fed to a filter 26 from which a residual product 30 is separated. This residual product 30. is conveyed by conveyor belts 19, 32 to the conveyor 7 and further to the collection vessel 4, while the harmless flue gases liberated from the residual product 30 are discharged through a chimney 27.

Opfindelsen er ikke begrænset til netop det her viste og beskrevne, og det skal bemærkes, at det for en fagmand vil være muligt at udføre en række modifikationer ved f.eks. ændring af flere roterovne eller forbrændingsriste. Som 25 nævnt i det foregående består dette i, at forbrændingsslagge og restprodukter, som ristegennemfald, flyveaske og reaktionsprodukter sammensmeltes i et procesforløb og uden mellemkøling, d.v.s. den engang frembragte energi i slaggen udnyttes til smelteprocessen.The invention is not limited to precisely what is shown and described herein, and it should be noted that it will be possible for a person skilled in the art to make a number of modifications by e.g. changing multiple rotary kilns or incinerators. As mentioned above, this consists in combustion slag and residual products, such as grate penetration, fly ash and reaction products, in a process and without intermediate cooling, i.e. the once generated energy in the slag is utilized for the melting process.
