Opfindelsen angår en fremgangsmåde til fremstilling af et brændbart produkt omfattende husholdningsaffald samt et flydende, brændbart materiale.The invention relates to a process for producing a combustible product comprising household waste as well as a liquid combustible material.
En fremgangsmåde til fremstilling af et brændbart produkt, af den i indledningen til krav 1 angivne art, kendes fra dansk patentansøgning nr. 484/74. Denne kendte fremgangsmåde lider af den ulempe, at den er forholdsvis langsom, besværlig og uøkonomisk.A process for producing a combustible product of the kind set forth in the preamble of claim 1 is known from Danish Patent Application No. 484/74. This known method suffers from the disadvantage of being relatively slow, cumbersome and uneconomical.
Opfindelsens formål er at angive en fremgangsmåde til fremstilling af et brændbart produkt af den i indledningen til krav 1 angivne art, hvilket brændbart produkt vil have en relativt høj brændværdi (f.eks. i sammenligning med affald fra private huse alene) og vil brænde jævnt, hvorved tillige fremgangsmåden er hurtigere, lettere og mere økonomisk end den kendte fremgangsmåde.The object of the invention is to provide a process for producing a combustible product of the kind set forth in the preamble of claim 1, which combustible product will have a relatively high calorific value (eg in comparison with waste from private houses alone) and will burn evenly. , whereby the method is also faster, easier and more economical than the known method.
Fremgangsmåden ifølge opfindelsen, der er af den i indledningen til krav 1 angivne art, er ejendommelig ved det i den kendetegnende del af krav 1 angivne. Det har ifølge opfindelsen vist sig, at findelingen lettes ved tilsætning af flydende, brændbart materiale, hvilken tilsætning ifølge opfindelsen finder sted forud for eller under findelingen (mens tilsætningen af flydende, brændbart materiale ved den kendte fremgangsmåde finder sted efter findelingen). Dette bevirker, at det til fremgangsmåden svarende apparatur i forbindelse med opfindelsen kan gøres mindre kompliceret end svarende til kendt teknik, ligesom fremgangsmåden ifølge opfindelsen kan gennemføres lettere og billigere end svarende til kendt teknik. Hertil kommer, at den kendte fremgangsmåde var forbundet med et alvorligt støvproblem, idet findelingen blev foretaget tørt, og at dette støvproblem er totalt elimineret ved fremgangsmåden ifølge opfindelsen, fordi den brændbare væske ved fremgangsmåden ifølge opfindelsen er tilsat før findelingen.The method according to the invention, which is of the kind set forth in the preamble of claim 1, is characterized by the method of claim 1. According to the invention, it has been found that the comminution is facilitated by the addition of liquid combustible material, which addition according to the invention takes place before or during the comminution (while the addition of liquid combustible material in the known process takes place after the comminution). This means that the apparatus corresponding to the method of the invention can be made less complicated than the prior art, and the method according to the invention can be carried out easier and cheaper than according to the prior art. In addition, the known process was associated with a severe dust problem in that the comminution was carried out dry and this dust problem is totally eliminated by the process of the invention because the combustible liquid of the process according to the invention is added before the comminution.
Opfindelsen omhandler således en fremgangsmåde til frem- 2 U4129 stilling af et brændbart produkt ud fra en blanding af fast affald fra private huse og forretninger og et flydende brændbart materiale, der vil gennembløde affaldsmaterialet.The invention thus relates to a process for producing a combustible product from a mixture of solid waste from private houses and shops and a liquid combustible material which will soak up the waste material.
Opfindelsen skal nu beskrives yderligere på eksemplificerende måde, tinder henvisning til en praktisk udførelsesform.The invention will now be further described in an exemplary manner, referring to a practical embodiment.
For at frembringe et brændbart produkt ud fra affaldsmaterialer bestående af en blanding af affald i form af fast stof og en brændbar væske, især olieslam af affaldskarakter, er det nødvendigt at sikre, at tørstoffet af blandingen nedbrydes til en partikelformet masse ved at udsætte den for en befugtningsproces og en mekanisk bearbejdning. Sædvanligvis er pulverisering og homogenisering, her tinder eet betegnet findeling, nødvendig for at slutproduktet fra processen på hensigtsmæssig måde kan behandles og brændes i ovne, f.eks. af den art, i hvilke man anvender "fyr af spredetypen" og bevægelige gitre.In order to produce a combustible product from waste materials consisting of a mixture of solid waste and a combustible liquid, in particular waste-grade oil sludge, it is necessary to ensure that the dry matter of the mixture is decomposed to a particulate mass by exposing it to a wetting process and a mechanical machining. Usually, pulverization and homogenization, here one termed comminution, is necessary in order that the final product of the process can be appropriately processed and burned in ovens, e.g. of the kind in which one uses the "scatter-type guy" and moving grids.
Et apparatur til findeling af fast affald fra private huse og forretninger består af en stor, roterende tromle, hvori det faste affald tilføres fra den ene ende.An apparatus for comminuting solid waste from private houses and shops consists of a large, rotating drum in which the solid waste is fed from one end.
Materialet i tromlen nedbrydes gradvist til relativt små partikler, efterhånden som det passerer fra indgangsenden af tromlen til udgangen deraf, på grund af tromlens rotation og den deraf følgende omvæltning i tromlen. Et sådant apparat er kendt, og det er i stand til at findele befugtet affald, såsom papir, pap og andre normale typer af affald fra private huse. Det netop angivne apparat vil dog ikke findele alle typer af fast, brændbart affaldsmateriale, men der foreligger naturligvis velkendte apparater til findeling af mange typer af materiale. I forbindelse med affald, såsom forretningsaffald bestående af træ og andre relativt hårde materialer, kan man f.eks. anvende et apparat som en kugleeller hammermølle for at findele materialet.The material in the drum is gradually decomposed into relatively small particles as it passes from the input end of the drum to its output, due to the rotation of the drum and the resulting upheaval in the drum. Such an apparatus is known, and it is capable of comminuting humid waste, such as paper, cardboard and other normal types of waste from private houses. However, the apparatus just stated will not comminute all types of solid, combustible waste material, but of course there are well known apparatus for comminuting many types of material. For example, in the case of waste, such as commercial waste consisting of wood and other relatively hard materials, use an apparatus such as a ball or hammer mill to comminute the material.
Fremgangsmåden ifølge opfindelsen til fremstilling af det 3 \U 129 brændbare produkt kræver i det væsentlige tilsætningen af flydende, brændbart materiale, såsom olieslam af affaldskarakter, i modsætning til den ikke brændbare væske, der normalt anvendes til at befugte affaldet, og opfindelsen er baseret på den erkendelse, at man ved tilsætning af et sådant brændbart, flydende materiale til findelingsappara-tet med roterende tromle, hvortil der er henvist i det foregående, opnår mulighed for at tilføre affaldsmateriale, der kan bestå af affald fra private huse og i forvejen findelt forretningsaffald eller findeleligt forretpingsaffald, i tromlen. Når tromlen holdes under rotation, og tørstofindholdet af det materiale, der findes deri, bliver gennemblødt med det flydende, brændbare materiale, opnår man findeling og nedbrydning af noget af de faste materialer, især de, der har en lav vådstyrke, hvilket understøttes af tilstedeværelsen af væske i tromlen.The process of the invention for preparing the 3U U12 combustible product essentially requires the addition of liquid combustible material, such as waste oil of sludge, as opposed to the non-combustible liquid normally used to moisten the waste, and the invention is based on the recognition that by adding such a combustible liquid material to the rotary drum comminution apparatus referred to above, it is possible to supply waste material which may consist of waste from private houses and already comminuted commercial waste or divisible commercial waste, in the drum. When the drum is kept in rotation and the solids content of the material contained therein is soaked with the liquid, combustible material, one achieves and decomposes some of the solid materials, especially those having a low wet strength, which is supported by the presence of fluid in the drum.
Som resultat af den kontinuerlige rotation og den deraf følgende blande- og findelingsvirkning bliver tørstoffet af affaldet nedbrudt og desuden overtrukket og/eller imprægneret med det flydende affald, og det materiale, der afgives fra enden af tromlen, sigtes for at muliggøre, at store stykker af materiale kan fjernes fra det partikelformede, brændbare materiale. Det fjernede materiale sorteres, og ethvert brændbart materiale bliver recirkuleret eller f.eks. udsat for behandling i en hammermølle, en udskæring eller lignende, før der foretages en recirkulering.As a result of the continuous rotation and the resulting mixing and comminution effect, the dry matter of the waste is degraded and additionally coated and / or impregnated with the liquid waste, and the material discharged from the end of the drum is screened to allow large pieces of material can be removed from the particulate combustible material. The removed material is sorted and any combustible material is recycled or e.g. subjected to treatment in a hammer mill, cutout or the like before recycling.
Forsøg har vist, at det er muligt at fremstille et brændbart materiale, der har en forbrændingsværdi af størrelsesordenen 20.500 kj/kg på tør, askefri basis, og det har vist sig, at denne forbrændingsværdi om nødvendigt kan forøges.Experiments have shown that it is possible to produce a combustible material having a combustion value of the order of 20,500 kJ / kg on a dry, ash-free basis, and it has been found that this combustion value can be increased if necessary.
Partikelstørrelsen af det fremstillede materiale viste sig at være tilfredsstillende til brænding i ovne af den art, som har et bevægende gitter, og det viste sig, at ikke brændbare materialer, der forelå inden i affaldet, såsom sønderbrudt glas, ikke gav anledning til smelteproblemerThe particle size of the material produced was found to be satisfactory for burning in furnaces of the type having a moving lattice and it was found that non-combustible materials present within the waste, such as broken glass, did not cause melting problems
