Description

DK 154452 BDK 154452 B

Opfindelsen angår et anlæg til forbrænding af fast og flydende affald og af den i indledningen til krav 1 angivne art.The invention relates to a plant for the incineration of solid and liquid waste and of the kind specified in the preamble of claim 1.

5 Opfindelsen har til formål at angive en ovn, der kan anvendes til forbrænding af en lang række forskellige spildprodukter eller affald, f.eks. i form af husholdningsaffald, kemisk affald, industriaffald, sygehusaffald.The invention has for its object to provide a furnace which can be used for the incineration of a wide variety of waste products or waste, e.g. in the form of household waste, chemical waste, industrial waste, hospital waste.

De i dag kendte affaldsforbrændingsanlæg er indrettet og 10 konstrueret til at bortskaffe eller forbrænde en enkelt af de nævnte affaldsarter eller i nogle tilfælde nogle få af disse affaldsarter på samme tid.The presently known waste incineration plants are designed and constructed to dispose of or incinerate a single of said waste species or, in some cases, a few of these waste species at the same time.

Disse kendte anlæg har naturligvis den ulempe, at der må installeres flere af slagsen på en forbrændingsanstalt, 15 dersom der skal kunne behandles affald af vilkårlig art.These known plants, of course, have the disadvantage that more of the kind must be installed on an incinerator 15 if waste of any kind is to be treated.

Da udviklingen har vist sig at gå imod færre, men meget store forbrændingsanlæg, er det nødvendigt, at disse anlæg er indrettet til at kunne behandle affald af så at sige enhver art.As the development has proven to go towards fewer but very large incineration plants, it is necessary that these plants are designed to treat waste of almost any kind.

20 Det ved opfindelsen tilsigtede formål opnås ved et anlæg, der er kendetegnet ved, at der er tilvejebragt særskilte indfyringsåbninger for ristesektionen, for slisken og for efterforbrændingskammeret for tilførsel af specifikke affaldsprodukter gennem nævnte åbninger.The object of the invention is achieved by a plant characterized in that separate firing openings are provided for the grate section, for the sludge and for the post-combustion chamber for supplying specific waste products through said openings.

25 Ved et på denne måde opbygget anlæg kan det lettere affald, såsom husholdningsaffald, bark og industriaffald, med en stor bestanddel af let brændbare materialer forbrændes i ristesektionen på i sig selv kendt måde. Det affald, der afgives fra ristesektionen, er fortørret og 30 nedstyrtes i roterovnen fra kanten af den sidste trapperist. Gennem en ved slisken anbragt indfyringsåbning kan der tilsættes "tæppet" af på slisken nedstyrtet affald yderligere affald i form af f.eks. kloakslam, malingrester, olie eller tilsvarende restprodukter fra den petro- 225 In a plant constructed in this way, the lighter waste, such as household waste, bark and industrial waste, with a large component of easily combustible materials can be incinerated in the grate section in a manner known per se. The debris emitted from the grate section is desiccated and disposed of in the rotary kiln from the edge of the last staircase grate. A blanket can be added to the slurry of waste deposited on the sludge by means of a firing opening located at the sludge in the form of e.g. sewage sludge, paint residue, oil or similar residues from the petro-2

kemiske industri. Dette flydende affald fordeles jævnt ud over den som følge af nedstyrtningen tilvejebragte store overflade ved det fra trapperistene afgivne affald. I den 5 efterfølgende roterovn udbrændes det på trapperistene fortørrede affald og det heri absorberede flydende affald fra slisken fuldstændigt, idet ovnens rotation sikrer, at alle partikler bliver udsat for oxidation ved høje temperaturer. Endelig vil der i efterforbrændingskammeret, hvor 10 den fra roterovnen afgivne forbrændingsgas typisk vil have en temperatur på mellem 750 og 1100°C, kunne foretages en forbrænding af forurenet spildevand, idet spildevandet kan tilføres gennem dyser i efterforbrændingskammeret.chemical industry. This liquid waste is evenly distributed over the large surface provided by the waste discharged from the stair grate. In the subsequent rotary kiln, the debris dried on the stair grates and the liquid waste absorbed from the sludge are completely incinerated, with the rotation of the furnace ensuring that all particles are exposed to oxidation at high temperatures. Finally, in the post-combustion chamber, where the combustion gas emitted from the rotary furnace will typically have a temperature of between 750 and 1100 ° C, contamination of contaminated wastewater can be effected, the waste water being supplied through nozzles in the post-combustion chamber.

Ifølge opfindelsen kan den mellem ristesektionen og 15 roterovnen anbragte sliske have en for affaldet uigennemtrængelig bundflade, og der kan være anbragt et antal brændere i sliskens bund for efterforbænding af det fra ristesektionen leverede affald for at bringe affaldet op på en temperatur, der er tilstrækkelig høj til den 20 efterfølgende forbrænding i roterovnen.According to the invention, the slides disposed between the grate section and the rotary furnace may have a waste impermeable bottom surface and a plurality of burners may be placed in the bottom of the slice for post-combustion of the waste delivered from the grate section to bring the waste up to a temperature sufficiently high. for the 20 subsequent combustion in the rotary kiln.

Den for affaldet uigennemtrængelige underside sikrer, at det til slisken tilførte flydende affald ledes videre til roterovnen. De i sliskens bund tilvejebragte brændere giver mulighed for en regulering af fortørringen af det 25 fra ristesektionen fremledte affald.The impermeable underside of the waste ensures that the liquid waste supplied to the sludge is passed on to the rotary kiln. The burners provided at the bottom of the slurry allow for the regulation of the drying of the waste generated from the grate section.

Ifølge opfindelsen kan den omkring en skråt nedadhældende akse roterende ovn have en konisk tilspidset eller indsnævret udgangsende.According to the invention, the rotary furnace may have a tapered or narrowed exit end about an oblique downwardly rotating axis.

Herved opnås, at det flydende affald forbliver i en 30 "lomme" ved roterovnens nedre del, indtil den fuldstændige forbrænding er sket.This results in the liquid waste remaining in a 30 "pocket" at the bottom of the rotary kiln until complete combustion has occurred.

Ved en i praksis foretrukken udførelsesform for et anlæg ifølge opfindelsen er der i efterforbrændingskammeret til- 3In a practically preferred embodiment of a plant according to the invention, in the post-combustion chamber, 3

vejebragt dyser for tilførsel af i særlig grad forurenet spildevand for forbrænding af det organiske materiale heri og fordampning af væskebestanddelen.provided nozzles for supplying particularly contaminated wastewater for combustion of the organic material therein and evaporation of the liquid component.

5 Herved udnyttes på hensigtsmæssig måde den i forbrændingsgassen fra roterovnen værende varmemængde til nedbrydning af selv svært forurenet spildevand.5 In this way, the amount of heat present in the combustion gas from the rotary kiln is used to decompose even badly polluted waste water.

Ved som foreslået ifølge opfindelsen at anbringe en eller flere spildoliebrændere i efterforbrændingskammeret opnås 10 der mulighed for at anvende spildolie til at øge temperaturen i efterforbrændingskammeret og derved forøge effektiviteten af forbrændingen af det nævnte forurenede spildevand.By placing one or more waste oil burners in the post-combustion chamber as proposed according to the invention, it is possible to use waste oil to increase the temperature of the post-combustion chamber and thereby increase the efficiency of the combustion of said contaminated waste water.

Opfindelsen skal i det følgende forklares nærmere under 15 henvisning til tegningen, på hvilken fig. 1 viser et skematisk tværsnit gennem et i overensstemmelse med opfindelsen udformet anlæg, og fig. 2 et snit efter linien 2-2 i fig. 1.The invention will be explained in more detail below with reference to the drawing, in which 1 shows a schematic cross-section through a system designed in accordance with the invention; and FIG. 2 is a sectional view taken along line 2-2 of FIG. First

Det i fig. 1 viste anlæg består af en ristesektion, der 20 under et er betegnet ved henvisningstallet 1, en sliske, der er betegnet ved henvisningstallet 2, en roterovn 3 og et efterforbrændingskammer 4.The FIG. 1 comprises a grate section 20 which is generally designated by reference numeral 1, a slurry designated by reference numeral 2, a rotary kiln 3 and a post-combustion chamber 4.

Den del af det til forbrænding bestemte affald, der består af forholdsvis let affald i form af husholdningsaffald, 25 bark eller industriaffald med et forholdsvis stort indhold af let brændbare materialer, tilføres gennem indfyringsskakten 7 ved anlæggets til venstre i fig. 1 viste ende.The portion of the waste for combustion, which consists of relatively light waste in the form of household waste, bark or industrial waste with a relatively high content of easily combustible materials, is fed through the firing shaft 7 at the plant to the left in fig. 1.

Det således tilførte materiale falder ned på de skråtstillede trapperiste, hvoraf der på tegningen er vist 30 to, som er betegnet ved henvisningstallene 8 og 9. Den ved forbrændingen dannede slagge udtømmes på kendt måde gennem de under ristene anbragte slaggesluser 10 og 11.The material thus supplied falls onto the inclined staircase, of which 30 are shown in the drawing, which are designated by reference numerals 8 and 9. The slag formed during combustion is discharged in a known manner through the slag locks 10 and 11 placed under the grids.

Fra risten 9's underkant styr tes den del af affaldet, der endnu ikke er forbrændt, men blot fortørret, ned på den skråtstillede slisk 2. Det fortørrede affald ophvirvles 5 ved denne nedstyrtning, og der kan derfor gennem indfyringsåbningen 5 tilsættes tungere affald i form af f.eks. afvandet kloakslam, der fordeles jævnt i det ophvirvléde, fortørrede affald.From the bottom of the grate 9, the part of the waste, which has not yet been incinerated, but simply dried, is directed down to the inclined sludge 2. The dried waste is swirled 5 by this crash, and therefore heavier waste can be added through the firing opening 5 in the form of eg. drained sewage sludge, which is evenly distributed in the swollen, dried up waste.

I slisken 2's bund kan der som antydet på tegningen være 10 anbragt brændere 6, der anvendes til opnåelse af en korrekt temperatur ved det til roterovnen tilførte affald.In the bottom of the chute 2, as indicated in the drawing, there may be 10 burners 6 used to obtain a correct temperature for the waste supplied to the rotary kiln.

Ved korrekt temperatur opnås en smeltning af produktet under fuldstændig nedbrydning af de kemiske stoffer, hvorved der fremkommer en ren, steril slagge.At the correct temperature, a melting of the product is achieved with complete degradation of the chemicals, resulting in a clean, sterile slag.

15 Som vist på tegningen har roterovnen 3 en konisk tilspidset udgangsende, der sikrer en tilbageholdelse af flydende affald. I roterovnen oxideres det fortørrede affald ved høje temperaturer, og der opnås derfor en fuldstændig udbrænding af materialet.15 As shown in the drawing, the rotary kiln 3 has a tapered tapered exit end ensuring a retention of liquid waste. In the rotary kiln, the dried waste is oxidized at high temperatures and therefore a complete combustion of the material is achieved.

20 Ved forbrænding af vanskeligt brændbare stoffer vil roterovnen modtage den ekstra nødvendige varme fra de i sliskens bund placerede brændere 6.20 In combustion of difficult combustible materials, the rotary kiln will receive the extra heat needed from the burners located in the bottom of the chute 6.

I efterforbrændingskammeret 4 foregår der en efterfor-brænding af de gasarter, der måtte have undgået 25 forbrænding i roterovnen 3.In the post-combustion chamber 4 there is a post-combustion of the gases which may have avoided combustion in the rotary kiln 3.

Som følge af efterforbrændingskammerets udformning vil forbrændingsgassen blive ophvirvlet, og der vil fremkomme en høj grad af sammenblanding, hvorved der kan opnås en fuldstændig forbrænding selv ved ringe lufttilførsel.As a result of the design of the post-combustion chamber, the combustion gas will be swirled and a high degree of mixing will be obtained, whereby complete combustion can be achieved even with low air supply.

30 I fig. 2 er det antydet, hvorledes affald i form af f.eks. afvandet kloakslam kan tilføres gennem den skråtstillede indfyringsslisk 5 for nedstyrtning på slisken 2.In FIG. 2 it is suggested how waste in the form of e.g. dewatered sewage sludge can be supplied through the inclined firing sludge 5 for crash on the sludge 2.

Det vil være muligt at udføre en række modifikationer, f.eks. anbringelsen af flere roterovne i serie efter hinanden eller parallelt samt tilvejebringelse af flere 5 skråtstillede slisker eller forbrændingsriste end de på tegningen viste, idet den til grund for opfindelsen liggende idé som nævnt i det foregående består i at kombinere flere i og for sig kendte forbrændingsanlægs sektioner og tilvejebringe indfyringsåbninger for tilfør-10 sel af affaldet til netop den sektion, hvori forbrændingen foregår mest effektivt for det pågældende produkt.It will be possible to make a number of modifications, e.g. the arrangement of several rotary kilns in series in succession or in parallel, and the provision of more inclined slides or combustion grids than those shown in the drawing, the idea underlying the invention as mentioned above consists of combining several sections of known combustion plants and providing firing openings for feeding the waste to the particular section in which the combustion takes place most effectively for that product.
