Die Erfindung betrifft auch eine Vorrichtung zur Durchführung des Verfahrens zur Wiederverwertung von sortenreinen oder ge mischten, sauberen oder verunreinigten Kunststoffabfällen durch Cracken dieser Substrate.The invention also relates to a device for carrying it out the process for recycling single-variety or ge mixed, clean or contaminated plastic waste Cracking these substrates.
Zum Stand der Technik der Verfahren und Vorrichtungen zur Wie derverwertung von sortenreinen oder gemischten, sauberen oder verunreinigten Kunststoffabfällen gehören die stoffliche und die chemische Wiederverwertung.The state of the art of methods and devices for how the recycling of single or mixed, clean or contaminated plastic waste includes the material and the chemical recycling.
Die Nachteile der stofflichen Wiederverwertung durch Sortierung der Kunststoffabfälle, Shreddern oder Mahlen, Reinigen, Trennen, Trocknen, Mischen, Schmelzen und Regranulieren liegen klar auf der Hand. Einerseits sind extrem hohe Sortierkosten aufzubringen und andererseits erreicht das Regranulat dennoch nicht die Qua lität von Primärgranulat.The disadvantages of recycling by sorting plastic waste, shredding or grinding, cleaning, separating, Drying, mixing, melting and regranulation are clear hand. On the one hand, extremely high sorting costs have to be paid and on the other hand the regranulate still does not reach the qua lity of primary granules.
Die mechanischen Eigenschaften sind beim Regranulat abgeschwächt und der Reinheitsgrad erreicht bestenfalls 98 bis 99%, d. h. es sind in der Regel noch zwischen 1 und 2% Schmutzpartikel mit einer Korngröße bis zu 200 µm im Regranulat.The mechanical properties of the regranulate are weakened and the degree of purity reaches 98-99% at best, i.e. H. it are usually between 1 and 2% dirt particles a grain size up to 200 µm in the regranulate.
Dies bedeutet, daß die Einsatzgebiete für solches Regranulat erheblich eingeschränkt sind. Es wird z. B. nie in Anwendungen vordringen können, die dem Lebensmittelrecht unterliegen. Sowohl der ökonomische als auch der ökologische Sinn solcher Verfahren ist daher umstritten.This means that the areas of application for such regranulate are significantly restricted. It is e.g. B. never in applications can advance that are subject to food law. Both the economic and the ecological sense of such Process is therefore controversial.
Die Nachteile der bekannten chemischen Wiederverwertungsverfah ren liegen in den hohen Behandlungstemperaturen.The disadvantages of the known chemical recycling process Ren are in the high treatment temperatures.
Als Verfahren bekannt sind die Pyrolyse, die Verschwelung, die Hydrolyse oder die Alkoholyse.Pyrolysis, the smoldering, are known as processes Hydrolysis or alcoholysis.
Bei Hydrolyse und Alkoholyse kommt nachteilig noch hinzu, daß hier nur sortenreine Kunststoffabfälle verarbeitet werden kön nen. Another disadvantage of hydrolysis and alcoholysis is that only pure plastic waste can be processed here nen.
Das grundsätzliche Problem bei Pyrolyse und Verschwelung liegt bei den hohen Behandlungstemperaturen, bei denen eine erhöhte Bildung von hochgiftigen Gasen auftritt, insbesondere eine er höhte Dioxin- und Furanbildung. Die großen Mengen an Schadstof fen, die hier auftreten, lassen sich bei diesen großen Mengen anteilen nur teilweise, wenn überhaupt, und auch dann nur sehr schwer aus der Abluft entfernen.The basic problem with pyrolysis and charring is at the high treatment temperatures at which an elevated Formation of highly toxic gases occurs, especially one he increased dioxin and furan formation. The large amounts of pollutants fen, which occur here, can be with these large quantities share only partially, if at all, and only then very much difficult to remove from the exhaust air.
Aufgabe der Erfindung war es deshalb, ein Verfahren und eine Vorrichtung zur Durchführung dieses Verfahrens bereitzustellen, die es ermöglichen, aus Kunststoffabfällen beliebiger Art wieder nutzbare Crackprodukte zu erhalten, ohne daß dadurch große Men gen an hochgiftigen, die Umwelt belastende Schadgase entstehen.The object of the invention was therefore a method and To provide a device for carrying out this method, which make it possible to recycle plastic waste of any kind to obtain usable cracking products without large menus genes of highly toxic, polluting gases.
Diese Aufgabe wird bezüglich des Verfahrens dadurch gelöst, daß der Crackprozeß im Niederdruckplasma durchgeführt wird und daß der Crackprozeß bei niedrigen Substrattemperaturen durchgeführt wird.With regard to the method, this object is achieved in that the cracking process is carried out in low pressure plasma and that the cracking process is carried out at low substrate temperatures becomes.
Bezüglich der Vorrichtung ist die Lösung der Aufgabe gekenn zeichnet durch eine Behandlungskammer, eine Plasmaerzeugungs einrichtung, eine Umwälzeinrichtung für das Plasmagas, eine Einrichtung zur Erzeugung von Niederdruck, eine Einrichtung zur Abführung des Crackgases, eine Reinigungseinrichtung für das Crackgas und Steuerungs- und Sicherungseinrichtungen.With regard to the device, the solution to the problem is known characterized by a treatment chamber, a plasma generation device, a circulating device for the plasma gas, a Device for generating low pressure, a device for Removal of the cracked gas, a cleaning device for the Crackgas and control and safety devices.
Besonders vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen zu finden.Particularly advantageous embodiments of the invention are in the Find subclaims.
Der besondere Vorteil der Erfindung liegt in den extrem niedri gen Substrattemperaturen, die durch die Behandlung im Nieder druckplasma ermöglicht werden. Bei diesen Temperaturen kann noch keine Dioxin- bzw. Furanbildung auftreten. Der weitere Vorteil liegt im frei wählbaren Plasma, das wiederum die Endprodukte beeinflußt.The particular advantage of the invention is the extremely low against substrate temperatures caused by the treatment in the low pressure plasma are made possible. At these temperatures can still no dioxin or furan formation occurs. The further advantage lies in the freely selectable plasma, which in turn is the end product influenced.
Die Erfindung wird nachfolgend beispielhaft beschrieben.The invention is described below by way of example.
Die beispielhafte Vorrichtung besteht in ihren Hauptbestandtei len aus einem Drehrohrofen mit Aluminiumoxidfenstern oder Quarz fenstern.The exemplary device consists of its main components len from a rotary kiln with aluminum oxide windows or quartz windows.
Aufgesetzt auf diese Fenster sind Mikrowellensender zur Erzeu gung des Plasmas im Drehrohrofen.Microwave transmitters are installed on these windows plasma in the rotary kiln.
Der Drehrohrofen ist geneigt und drehbar ausgeführt. In seinem Inneren befinden sich Schaufeln.The rotary kiln is inclined and rotatable. There are blades inside.
Im Inneren ist über eine Vakuumpumpe, z. B. einem Trockenläufer, bestehend aus Klauenpumpe und innerer Rootskaskade, evtl. mit vorgeschalteter Rootspumpe oder vorgeschalteter Rootskaskade, ein Druck von 1 mbar einhaltbar.Inside is a vacuum pump, e.g. B. a dry runner, consisting of claw pump and inner root cascade, possibly with upstream root pump or upstream root cascade, a pressure of 1 mbar can be maintained.
Durch eine Rootspumpenkaskade ist die Abführung der Crackgase möglich. The crack gases are removed through a root pump cascade possible.
Als Plasmagas wird Wasserstoff verwendet.Hydrogen is used as the plasma gas.
Die Zuführung der Kunststoffabfälle erfolgt am oberen Ende des Drehrohrofens über ein Schleusensystem.The plastic waste is fed in at the upper end of the Rotary kiln over a lock system.
Die Kunststoffabfälle werden durch die Drehbewegung und die Schaufeln im Innern des Drehrohrofens langsam durch das Nieder druckplasma aus Wasserstoff weiterbefördert.The plastic waste is caused by the rotary motion and the Slowly shovel inside the rotary kiln through the low pressurized plasma from hydrogen.
Es erfolgt eine Vercrackung der Kunststoffabfälle bei einer Temperatur von 200°C. Das bedeutet, daß noch keine Schädigung irgendwelcher Zusatzstoffe im Kunststoff erfolgt und daß noch keine Dioxine und Furane gebildet werden.There is a cracking of the plastic waste at one Temperature of 200 ° C. That means no harm yet any additives in the plastic and that still no dioxins and furans are formed.
Nachdem der Kunststoff vollständig in Gase, und zwar zum großen Teil in Methan zerlegt ist, verbleiben im Drehrohrofen nur noch die festen Zusatzstoffe und Schmutzpartikel. Diese werden aus dem Drehrohrofen kontinuierlich ausgetragen.After the plastic is completely in gases, and to the large Part is broken down into methane, only remain in the rotary kiln the solid additives and dirt particles. These are made continuously discharged into the rotary kiln.
Die entstandenen Crackgase werden in einer Gaswaschanlage gerei nigt, z. B. von entstandenem Chlorwasserstoffgas befreit, aus dem Salzsäure zurückgewonnen werden kann und können anschließend wieder in chemische Prozesse eingeführt werden. Sie können also beispielsweise hergenommen werden, um wieder neue Kunststoffe herzustellen.The crack gases produced are cleaned in a gas washing plant nigt, e.g. B. freed from the resulting hydrogen chloride gas from the Hydrochloric acid can and can subsequently be recovered reintroduced into chemical processes. So you can for example, be taken to get new plastics to manufacture.
