Frembringelsens anvendelsesområdeScope of production
Systemet kan bruges til at opdele energiholdige eller andre faste stoffer, indeholdende både flydende og faste bestanddele, i mindst 2 fraktioner, der i samme produktionsgang efterfølgende filtreres for den eller de flydende fraktioners vedkommende, eller transporteres til afbrænding eller anden videre behandling for den eller de faste fraktioners vedkommende.The system can be used to divide energy-containing or other solids, containing both liquid and solid constituents, into at least 2 fractions, which are subsequently filtered for the liquid fraction (s) or transported for incineration or other further treatment for the one or the other (s). in the case of fixed fractions.
Systemet er udviklet til udvinding og filtrering af planteolie fra olieholdige frø, med samtidig afbrænding af faststofdelen, men kan i princippet bruges til andre medier, som for eksempel udpresning og filtrering af fedtstoffase fra animalske produkter, hvor faststoffet for eksempel kan afbrændes eller benyttes på anden måde.The system is designed for extraction and filtration of vegetable oil from oily seeds, with the simultaneous burning of the solid part, but can in principle be used for other media, such as extruding and filtering fat phase from animal products, where the solid can, for example, be burnt or used on another manner.
Kendt teknikPrior art
Opdeling af olie- eller fedtholdige medier i en eller flere faste fraktioner og en eller flere flydende faser ved hjælp af mekanisk sammenpresning er kendt i mange afskygninger, både som stempelpresser, skruepresser og forskellige pumpesystemer. Den oftest anvendte fremgangsmåde for planteolie, er at benytte en skruepresse til fraktioneringen, hvorefter følger en bundfældning af oliefraktionen, da der rives en del faststof med, når olien forlader pressen. Efter bundfældning har man en oliefraktion, der kan filtreres, og et olieholdigt slam. Faststoffasen (pressekage) kan gå til videre forarbejdning (f.eks. kemisk ekstrahering af resterende olie), eller benyttes som foder eller brændsel.Splitting of oil or grease media into one or more solid fractions and one or more liquid phases by mechanical compression is known in many shadows, both as piston presses, screw presses and various pumping systems. The most commonly used method for vegetable oil is to use a screw press for the fractionation, followed by a precipitation of the oil fraction, as some solid is rubbed off as the oil leaves the press. After settling, there is a filterable oil fraction and an oily sludge. The solid phase (press cake) can be used for further processing (eg chemical extraction of residual oil), or used as feed or fuel.
Den ovenfor beskrevne teknik benyttes hovedsageligt i større centrale anlæg med meget høj kapacitet, der leverer proteinfoder til landbruget, og olie til fødevareindustrien og transportsektoren.The above-described technique is mainly used in large central plants with very high capacity supplying protein feed for agriculture, and oil for the food industry and the transport sector.
Der findes også nogle fa (i DK) gårdanlæg, der har kapacitet på ned til 15-20 kg ffø/time, og som benytter ovenstående teknik, på nær ekstraheringen.There are also some farms (in DK) that have a capacity of down to 15-20 kg per hour and which use the above technique, except for the extraction.
Pressekagen bruges som proteinfoder til gårdens dyr, og olien afbrændes eksempelvis i specielle fyr, eller bruges i ombyggede traktorer eller biler.The press cake is used as protein feed for farm animals, and the oil is burned, for example, in special lighthouses or used in converted tractors or cars.
2 2DK 2003 00359 Y6 Fælles for den her beskrevne teknik er, at når pressen er standset og kold er den vanskelig eller umulig at genstarte på grund af stivnet pressekage i pressezonen, hvorfor den adskilles og rengøres efter endt brug.2 2GB 2003 00359 Y6 Common to the technique described here is that when the press is stopped and cold it is difficult or impossible to restart due to stiffened press cake in the press zone, which is why it is separated and cleaned after use.
Fra CA 2,260,614 kendes et anlæg til presning af biologisk materiale, hvor anlægget er arrangeret i en container eller lastbils anhænger. Anlægget omfatter en indløbstragt, der leder materialet videre til en presse. Fra pressen er der afløb til en opsamlingsenhed for den flydende fraktion samt den ikke flydende fraktion. Den flydende fraktion kan endvidere filtreres.From CA 2,260,614 there is known a plant for pressing biological material where the plant is arranged in a container or truck trailer. The plant comprises an inlet hopper which conveys the material to a press. From the press there is a drain to a collection unit for the liquid fraction as well as the non-liquid fraction. The liquid fraction can also be filtered.
Fra US-A-4,024,168 kendes en skruepresse til kombineret knusning og komprimering af specielt nødder. Pressen er endvidere udstyret med midler for bortledning af planteolier samt for opvarmning af den resterende masse, således, at der ved behandlingen i skruepressen af for eksempel nødder, frembringes en tør ristet nøddemasse samt en vegetabilsk (nødde) olie fraktion.From US-A-4,024,168 a screw press is known for the combined crushing and compression of special nuts. The press is also equipped with means for draining plant oils and for heating the remaining mass, so that, for example, in the screw press of nuts, a dry roasted nut mass and a vegetable (nut) oil fraction are produced.
Det tekniske problem, der skal løsesThe technical problem to be solved
Den hidtil kendte teknik har kapacitet og opbygning, der besværliggør decentral produktion og anvendelse af olieholdige plantefrø som energikilde i en almindelig husstand, og derved er den en væsentlig forhindring for udbredelsen af denne miljøvenlige energikilde til en større del af den decentrale energiforsyning.The prior art has the capacity and structure that makes decentralized production and use of oilseed plant seeds as an energy source in an ordinary household, thereby making it a significant obstacle to the distribution of this environmentally friendly energy source to a larger part of the decentralized energy supply.
Der er følgende hovedproblemer ved udnyttelse af eksisterende teknik decentralt, i den enkelte husstand: I en almindelig husstand er der sjældent husdyr nok til at udnytte den mængde pressekage til foder, der bliver lavet for at kunne udnytte olien til opvarmning eller transport i husstanden. Der må findes en alternativ anvendelse af pressekagen.There are the following main problems with utilization of existing technology decentralized, in the individual household: In an ordinary household, there are rarely enough livestock to utilize the amount of press cake for feed that is made to utilize the oil for heating or transport in the household. An alternative use of the press cake must be found.
1 forbindelse med den nødvendige bundfældning af faststoffet i olien, laves der en mængde olieholdigt slam, som man ikke har mulighed for at udnytte. Slam- 3 3DK 2003 00359 Y6 met bliver et affaldsproblem, selvom det har et højt energiindhold. Produktionen af dette biprodukt må undgås, eller reduceres til et minimum.In connection with the necessary precipitation of the solid in the oil, an amount of oily sludge is made which is not possible to utilize. The sludge 3 3DK 2003 00359 Y6 meter becomes a waste problem, even though it has a high energy content. The production of this by-product must be avoided or reduced to a minimum.
Arbejdet med at adskille og rengøre pressen efter endt kørsel gør, at det ikke er realistisk at benytte sig af eksisterende teknik i en decentral produktion i en almindelig husstand. Skal udnyttelsen af olieholdigt frø som decentral energikilde have større udbredelse end i dag, må dette arbejde fjernes, så der bliver tale om en fuldautomatisk proces, der kan startes og stoppes efter behov.The work of separating and cleaning the press after the end of the run makes it unrealistic to use existing technology in a decentralized production in an ordinary household. If the utilization of oily seeds as a decentralized energy source is to be more widespread than today, this work must be removed so that it is a fully automatic process that can be started and stopped as needed.
Hidtidige erfaringer med afbrænding af rent, olieholdigt frø som raps i almindelige stokeranlæg har vist, at olien kan frigives på en sådan måde, at den ikke afbrændes, men ophobes i brænderen eller løber ud af denne, med deraf følgende komplikationer og brandfare. Der må udvikles en enhed, der sikkert og uden driftstop kan afbrænde den producerede pressekage.Previous experience with burning of clean, oily seeds such as canola in ordinary stoker plants has shown that the oil can be released in such a way that it is not burnt, but accumulates in the burner or runs out of it, resulting in complications and fire hazards. A device must be developed that can safely and without interruption burn the produced cake.
Den nye teknikThe new technique
Det nye ved frembringelsen er, at der er sammenbygget en enhed, bestående af en oliepresse, en brænder af stokertype og en filterenhed.What is new about the generation is that a unit is composed of an oil press, a stoker type burner and a filter unit.
Det nye ved oliepressen er, at indløbssektionen er udført med skruevindinger, der reduceres i volumen igennem indløbszonen, hvorved opbygges en internt tryk, der muliggør integreret filtrering af olien, så der ikke opstår et affaldsproblem i form af olieholdigt slam.What is new about the oil press is that the inlet section is made with screw turns that are reduced in volume through the inlet zone, thus creating an internal pressure which allows integrated filtration of the oil so that no waste problem in the form of oily sludge is created.
Det nye ved brænderenheden er, at op tændingen sker ved brug af varm luft.The new thing about the burner unit is that the ignition is done using hot air.
Den tekniske virkningThe technical impact
Sammenbygningen af oliepresse, stoker og filterenhed bevirker, at det er muligt at foretage en fuldstændig automatiseret, kontinuert omdannelse af f.eks. olieholdigt planteffø til de to slutprodukter; flydende biobrændstof, og opvarmningsenergi.The assembly of the oil press, stoker and filter unit means that it is possible to carry out a fully automated, continuous conversion of e.g. oily plant seed for the two end products; liquid biofuel, and heating energy.
4 4DK 2003 00359 Y64 4GB 2003 00359 Y6
Det, at systemet er fuldt automatiseret, bevirker, at der for det første ikke kræves særlige kvalifikationer hos brugeren af systemet, for det andet, at energien kan leveres på det tidpunkt, der er brug for den, uden indsats fra brugerens side.The fact that the system is fully automated means that, firstly, no special qualifications of the user of the system are required, secondly, that the energy can be delivered at the time it is needed, without any effort on the part of the user.
Dette gøres i praksis ved, at varmebehovet i boligen, via kedeltemperaturen på centralvarmeanlægget, bestemmer, hvornår anlægget startes/stoppes.This is done in practice by the heating demand in the home, via the boiler temperature of the central heating system, determines when the system is started / stopped.
Olien til transportbrændstof opsamles løbende i lagertank, klar til anvendelse.The transport fuel oil is collected continuously in a storage tank, ready for use.
Husstandens samlede årlige motorbrændstofbehov danner grundlag for justering af olieudbyttet, så der kun produceres den mængde motorbrændstof, der er nødvendig, mens resten af olien forbliver i pressekagen, og øger dennes brændværdi.The household's total annual engine fuel needs form the basis for adjusting the oil yield to produce only the amount of engine fuel needed while the rest of the oil remains in the press cake, increasing its calorific value.
På oliepressen (Figur 1) er skruen tilvirket på en måde, der gør, at det frø, der løber ind i pressen gennem indløbszonen bliver komprimeret tilstrækkeligt i pakkezonen til at virke som en pakning, der forhindrer den luft og olie, der ellers vil løbe frit bagud gennem det indkommende frø, i at trænge tilbage til indløbszonen.On the oil press (Figure 1) the screw is manufactured in a way that causes the seed running into the press through the inlet zone to be compressed sufficiently in the packing zone to act as a gasket which prevents the air and oil that would otherwise run freely backward through the incoming seed, in returning to the inlet zone.
Frøet løber uden mekanisk sammentrykning videre gennem overtrykszonen, frem til pressezonen, lige bagved dysen, hvor olien frigives under meget højt tryk. Efter frigivelsen løber olien tilbage i overtrykszonen, fordi trykket her er lavere, end i pressezonen. Samtidig presses faststoffet (pressekagen) gennem dysen, der former pressekagen til en pille, der fungerer som brændsel for brænderenheden, 1 overtrykszonen er det integrerede filter indbygget i pressesvøbet, så når olien løber tilbage i modsat retning af det ubearbejdede frø, presses den ud gennem filteret af det opbyggede tryk. Dette opbyggede tryk gør det muligt at benytte filtermateriale af stor finhed, hvilket minimerer fremkomsten af uønsket bundfældningsslam senere i processen. Hoveddelen af det faststof, der ellers ville ende som slam, bliver altså holdt tilbage i pressen, og indgår i det faste stof, der udgør brændsel til brænderen.The seed runs without mechanical compression through the overpressure zone, up to the pressing zone, just behind the nozzle where the oil is released under very high pressure. After release, the oil returns to the overpressure zone because the pressure here is lower than in the press zone. At the same time, the solids (press cake) are pressed through the nozzle which forms the press cake into a pill which acts as fuel for the burner unit, in the overpressure zone the integrated filter is built into the press wrapper so that when the oil runs back in the opposite direction of the unprocessed seed, it is pressed out through the filter of the built-up pressure. This build-up pressure allows the use of filter material of great fineness, which minimizes the appearance of unwanted sludge sludge later in the process. The main part of the solid that would otherwise end up as sludge is thus retained in the press, and is included in the solid which constitutes fuel for the burner.

Optænding afbrænderenheden er som de øvrige processer fuldt automatiseret, idet der benyttes en varmeblæser til dette. Brugen af varm luft sikrer, at der sker en effektiv overførsel af varme til den pressekage, der skal antændes, uden fysisk kontakt mellem varmelegeme og pressekage. Dette bevirker, at der ikke sker fastbrænding af slagge på varmelegemet, hvilket ellers ville gøre optændingen mindre effektiv, og forkorte varmelegemets levetid. Udtørringsfasen, der skal gennemgås før røggassen udvikles, bliver ligeledes forkortet, idet vanddampen fjernes øjeblikkeligt med den gennemstrøm-mende varme luft. Samtidig leverer luften den ilt, der er nødvendig for antænding af røggassen. Disse faktorer i kombination resulterer i en hurtig og effektiv optænding, som er meget vigtig for, at holde røgudviklingen, og dermed miljøbelastningen, på et minimum ved drift af systemet.The ignition of the burner unit is fully automated like the other processes, using a heat fan for this. The use of hot air ensures that efficient heat is transferred to the press cake to be ignited without physical contact between the heater and the press cake. This means that no slag is burned on the heater, which would otherwise make the ignition less efficient and shorten the life of the heater. The desiccation phase, which must be reviewed before the flue gas is developed, is also shortened as the water vapor is immediately removed with the hot air flowing through. At the same time, the air supplies the oxygen needed to ignite the flue gas. These factors in combination result in a quick and efficient ignition, which is very important for keeping the smoke evolution, and thus the environmental impact, at a minimum when operating the system.

UdførelseseksemplerEmbodiments
Det aktuelle system er monteret på en kedel, der er koblet op mod et centralvarmeanlæg i en almindelig husstand på 150 m2, hvor der skal leveres rumvarme og varmt brugsvandThe current system is mounted on a boiler that is connected to a central heating system in an ordinary household of 150 m2, where room heating and hot domestic water are to be supplied.
Systemet består af først en presse med en kapacitet på 2,5 kg frø/time, hvilket svarer til en samlet frigivet effekt på ca. 16 kW.The system first consists of a press with a capacity of 2.5 kg seeds / hour, which corresponds to a total released power of approx. 16 kW.
Ved indstilling af pressen til f. eks 10 % olieudbytte kan den frigivne effekt opdeles i ca. 0,25 ltr olie/time (ca. 4 km kørsel ved 17 km/ltr) og ca.2,25 kg pressekage (14,5 kW indfyret effekt i brænder).By setting the press to eg 10% oil yield, the released power can be divided into approx. 0.25 ltr oil / hour (approx. 4 km driving at 17 km / ltr) and approx. 2.25 kg press cake (14.5 kW fired power in burner).
Hvis der er behov for større olieproduktion indstilles pressen til større udbytte, det kunne f.eks. se således ud: 35 % olieudbytte svarer til en olieproduktion på ca. 0,93 Itr/time (ca 16 km kørsel ved 17 km/ltr) og en produktion af pressekage svarende til 8,4 kW indfyret effekt i brænderen.If there is a need for greater oil production, the press is adjusted to greater yields. look like this: 35% oil yield corresponds to an oil production of approx. 0.93 Itr / hour (approx. 16 km driving at 17 km / ltr) and a production of press cake corresponding to 8.4 kW fired power in the burner.

Det er muligt at indstille systemet, ved hjælp af udbyttet og hastigheden (kapaciteten) på pressen, så det dækker det samlede kørselsbehov og rumopvarmning for langt den største del af de danske enkelthusstande.It is possible to adjust the system, using the yield and the speed (capacity) of the press, to cover the total driving needs and space heating for the vast majority of the Danish single-family homes.
Idet systemet kun kører i det omfang, der er behov for rumvarme, er der ikke brug for opbevaring af pressekage, der har en kort holdbarhed, i stedet opbevares energien på frøform, en meget mere stabil løsning (frøet er jo "beregnet” til at holde indtil næste spiresæson). Desuden er energitætheden pr. volumenenhed så stor, at ca. 10 m3 opbevaringssilo vil være tilstrækkelig til et års forbrug for de fleste almindelige husstande. En anden fordel ved dette er, at frøet kan købes, når det er mest fordelagtigt (høst), og med en lav transportomkostning (kun en kørsel/år).Since the system runs only to the extent needed for space heat, no storage of press cake having a short shelf life is needed, instead the energy is stored in seed form, a much more stable solution (the seed is "intended" to In addition, the energy density per unit volume is so large that about 10 m3 of storage silo will be sufficient for one year of consumption for most ordinary households. Another advantage of this is that the seed can be purchased when it is most advantageous (harvest), and with a low transport cost (only one drive / year).
Til sammenligning ville samme 10 m3 silo skulle fyldes 2-3 gange på et år, hvis der blev fyret med træpiller. Her er man tvunget til at købe piller på tidspunkter, hvor det er mindst fordelagtigt (i fyringssæsonen), samtidig med, at der skal betales for 2-3 gange transport.In comparison, the same 10 m3 silo would need to be filled 2-3 times in a year if fired with wood pellets. Here you have to buy pills at times when it is least advantageous (during the heating season), while paying for 2-3 times transport.
Pressen tager selv frøet fra siloen, via en almindelig plasticslange med fald på.The press even takes the seed from the silo, via a regular plastic hose with drops.
Efter presning transporteres pilien via en lille fødesnegl, trukket af pressemotoren, til brænderen, der er opbygget som en stokerbrænder, med luftforsyning via blæser, der er reguleret efter iltindholdet i røggassen (med lambdasonde). Start og stop afbrænderen, samt indfyret effekt styres via PLC af husstandens behov for rumvarme og varmt vand.After pressing, the pili is transported via a small feed auger, pulled by the press motor, to the burner, which is built like a stoker burner, with air supply via blower which is regulated according to the oxygen content of the flue gas (with lambda probe). Start and stop of the burner, as well as the fired power is controlled via PLC by the household's need for space heating and hot water.
Brænderen optændes automatisk ved hjælp af 1,5 kW varmeblæser, der typisk optæn-der brænderen på ca. 2,5 min.The burner is automatically ignited by means of 1.5 kW heat blowers, which typically ignite the burner of approx. 2.5 min.
Olien forlader pressen gennem en filterflade, der er glat på siden ind mod skruen, så der ikke sætter sig urenheder i filteret. Efter denne integrerede filtrering, der tilbageholder en stor del af det faststof, der ellers ville løbe ud med olien, løber olien ned i en lille pumpesump, hvorfra en almindelig oliefyrspumpe (trukket af pressemotoren) DK 2003 00359 Y6 7 pumper olien over først et almindeligt dielsebil-brændstoffilter på ca 14 my, og derefter i seriekobling med dette et 3 my absolutfilter.The oil leaves the press through a filter surface that is smooth on the side towards the screw, so that no impurities settle in the filter. After this integrated filtration, which retains a large part of the solid that would otherwise run out with the oil, the oil runs into a small pump sump, from which an ordinary oil fired pump (drawn by the press engine) pumps the oil over an ordinary part-car fuel filter of about 14 microns, and then in series coupling with this a 3 microns absolute filter.
Efter denne behandling er olien klar til anvendelse i en dieselmotor, modificeret til 5 koldpresset vegetabilsk olie 1.After this treatment, the oil is ready for use in a diesel engine, modified to 5 cold pressed vegetable oil 1.
