Description
Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, welches durch die gesteuerte Tieftemperaturentgasung zerkleinerter, organischer Stoffe, vorzugsweise von Altreifen, Kunststoffen, Elektronikschrott usw. auf die Wiedergewinnung von Rohstoffen abgestellt ist.The object of the invention is to provide a method which by controlled low-temperature degassing shredded, organic substances, preferably from Used tires, plastics, electronic waste, etc. on the Recovery of raw materials is turned off.
Vom Stand der Technik her sind unzählige Verfahren bekannt, aber keines hat bisher das Problem des Altreifenanfalls, des Kunststoffabfalls (z. B. Kunststoffmüll, Schreddergut usw.) oder des Elektronikschrotts lösen können, obwohl in diesen Abfällen große Mengen der verschiedensten Rohstoffe gebunden sind.Countless methods are known from the prior art, but none has the problem of old tire attack so far, plastic waste (e.g. plastic waste, Shredded material etc.) or the electronic scrap can, although in these wastes large amounts of various raw materials are bound.
Ein ähnlicher Hohlschneckengenerator wurde unter OS-DE 38 09 115 zur Dekontaminierung von Böden beschrieben.A similar hollow screw generator was developed under OS-DE 38 09 115 for decontamination of floors.
Gelöst wird die Aufgabe durch Anspruch 1 sowie der Unteransprüche.The task is solved by claim 1 and the subclaims.
Der Erfindung liegt die Aufgabe zugrunde, in den Temperaturbereichen von etwa 150°C - 350°C - 450°C große Mengen von Entgasungsprodukten in möglichst reiner Form zu erhalten. Erreicht wird dies durch die engen, sich dauernd verändernden Räumlichkeiten in den sich langsam drehenden Schneckenzügen, wodurch schnelle eine große Mengen von Strahlungswärme, aber auch Kontaktwärme an das Entgasungsgut übertragen wird.The invention has for its object in the temperature ranges from about 150 ° C - 350 ° C - 450 ° C large quantities of degassing products in as pure as possible To get shape. This is achieved through the narrow, constantly changing premises in the slow rotating snail trains, making fast one large amounts of radiant heat, but also contact heat is transferred to the degassing material.
Die Stufe bis etwa 150°C ist hauptsächlich der Trocknung sowie der Abspaltung hygroskopischer Wässer vorbehalten, denn es ist wichtig, soviel Wasser wie möglich aus dem Prozeß zu entfernen.The stage up to about 150 ° C is mainly that Drying and the separation of hygroscopic water reserved, because it is important to use as much water as possible remove from the process.
Die nachfolgende zweite und dritte Stufe bieten den Vorteil, daß zunächst eine grobe Auftrennung des komplex zusammengesetzten, flüssigen Kondensats erfolgt und beide Fraktionen als Rohstoff hochinteressant sind. Die Flüssigprodukte können bis zu 90% je nach Einsatzmaterial erreichen. Das Kondensat enthält vornehmlich u. a. aliphatische Kohlenwasserstoffe und Olefine, das in Prozessen zur Rückgewinnung von Ethylen und Propilen aber auch von monomerem Styrol und anderen Chemierohstoffen führt.The subsequent second and third stages offer the advantage that first a rough breakdown of the complex composite liquid condensate and both Fractions are extremely interesting as a raw material. The liquid products can be up to 90% depending on the input material to reach. The condensate mainly contains u. a. aliphatic Hydrocarbons and olefins in processes for the recovery of ethylene and propiles but also of monomeric styrene and other chemical raw materials.
In einer der Gasreinigung nachgeschalteten Tiefkühlung wird das restliche Produktgas auf etwa 5°C abgekühlt, wobei eine hochwertige BTX-Fraktion auskondensiert. Die festen Rückstände fallen im wesentlichen, nachdem Metalle (z. B. Teile der Stahlgürtelreifen) und anderes inerte Material entfernt wurde, als kohlenstoffreiches, rieselfähiges, geruchloses Material an. Aufgrund ihres hohen Heizwertes von über 33 500 kj/kg besteht die Möglichkeit, sie als Brennstoff oder nach entsprechender Aufbereitung als Füll- oder Farbstoff in der chemischen oder Gummiindustrie einzusetzen.In a freezer downstream of the gas cleaning system the remaining product gas is cooled to about 5 ° C, a high-quality BTX fraction condenses out. The solid residues essentially fall after Metals (e.g. parts of the steel belted tires) and others inert material was removed as a high carbon, free-flowing, odorless material. Because of her there is a high calorific value of over 33 500 kj / kg Possibility to use them as fuel or after Processing as filler or dye in chemical or rubber industry.
Der Ein- oder Austrag des Materials in und aus dem Hohlschneckenreaktor erfolgt über eine Schleuse, wie natürlich der gesamte Prozeß unter Luftabschluß abläuft. In weiterem hat sich herausgestellt, daß die Kondensationskühler am besten mit Luft betrieben werden, um vom Wasser unabhängig zu sein. Durch dieses Verfahren ist auch die Trocknung sowie Entgasung von Klärschlamm möglich.The entry or exit of the material in and out of the hollow screw reactor takes place via a lock, of course the entire process takes place in the absence of air. It has further been found that the condensation cooler best to be operated with air from the Water to be independent. Through this procedure also the drying and degassing of sewage sludge possible.
Claims (5)
- - in einem ein- oder mehrstufigen Hohlschneckenreaktor, bei dem die einzelnen Stufen übereinander angeordnet und dieselben untereinander durch Schleusen getrennt sein können, in einem oder mehreren Kreisläufen Wärmeträger zirkulieren, die im Trocknungs- und Entgasungsgut getrennt verschiedene Temperaturbereiche zulassen und somit die Entgasungsprodukte von jeder Stufe getrennt abgezogen werden können,
- - es sich um Einzel- als auch um Doppelschnecken handeln kann, die in oben verschlossenen Doppelmanteltrögen gelagert sind.
- - In a single-stage or multi-stage hollow screw reactor, in which the individual stages are arranged one above the other and separated from one another by locks, heat carriers circulate in one or more circuits which allow different temperature ranges in the material to be dried and degassed, and thus the degassing products from each stage can be deducted separately
- - It can be single as well as twin screws, which are stored in sealed double-walled troughs.
