Description
Eine Beschickungseinrichtung einer Anlage zur Verarbeitung kohlenstoffhaltiger Rohstoffe A charging device of a plant for processing carbonaceous raw materials
Die Erfindung betrifft Beschickungseinrichtungen von Anlagen zur Verarbeitung kohlenstoffhaltiger Rohstoffe wie Gasgeneratoren, Öfen, Kessel u. ä. und kann in Anlagen zur Verarbeitung von Haushalts- und Industrieabfällen eingesetzt werden.The invention relates to charging devices of plants for processing carbonaceous raw materials such as gas generators, stoves, boilers u. Ä. And can be used in plants for processing household and industrial waste.
Bekannt ist eine Beschickungseinrichtung, insbesondere für eine Anlage zur Verbren- nung in Stücken geschnittenen Materials, ausgeführt in Form eines vertikalen Fallrohres und eine Beschickungskammer und eine abdichtbare Kammer enthaltend, die in einer Reihe untereinander angeordnet sind. Die abdichtbare Kammer ist von der Beschickungskammer und von der Anlage durch Verschlüsse getrennt, die beispielsweise als Schieber mit Antrieben ausgeführt sind.Known is a charging device, in particular for a plant for incineration in pieces cut material, carried out in the form of a vertical downpipe and containing a feed chamber and a sealable chamber, which are arranged in a row with each other. The sealable chamber is separated from the loading chamber and from the plant by closures, which are designed, for example, as slides with drives.
Von Nachteil bei dieser Einrichtung ist es, dass es bei der Verarbeitung (Verbrennung) von Kunststoffabfällen, insbesondere von thermoplastischen Kunststoffen, und angesichts der hohen Temperaturen in der Anlage zu einem Festkleben der zu verarbeitenden Rohstoffe am Schieber kommen kann, der die abdichtbare Kammer von der Anlage trennt. Die Abgastemperatur im oberen Teil der Anlage übersteigt 200 0C, wohingegen der Schmelzpunkt z.B. von Polyethylen zwischen 100...135 0C liegt. Das Festkleben der Rohstoffe am Schieber kann zum Verklemmen des Schiebers führen, was zu einem Stillstand nicht nur der Beschickungseinrichtung sondern der Anlage insgesamt führt. Urigeplante und geplante Stillstandszeiten für die Schieberreinigung vermindern die Produktivität der Anlage.A disadvantage of this device is that it can come in the processing (combustion) of plastic waste, especially of thermoplastics, and in view of the high temperatures in the system to sticking the raw materials to be processed on the slider, the sealable chamber of the Plant separates. The exhaust gas temperature in the upper part of the plant exceeds 200 0 C, whereas the melting point of polyethylene, for example, between 100 ... 135 0 C. The sticking of the raw materials on the slide can lead to jamming of the slide, which leads to a standstill not only of the feeder but of the plant as a whole. Urineplante and planned downtime for the slide cleaning reduce the productivity of the plant.
Aufgabe, auf deren Lösung die Erfindung abzielt, ist die Erhöhung der Betriebszuverlässigkeit der Beschickungseinrichtung durch Verhinderung eines möglichen Festkle- bens von zu verarbeitenden thermoplastischen Rohstoffen am Verschluss, der die Be- schickungseinrichtung von der Rohstoffverarbeitungsanlage trennt.The object of the invention is to increase the operational reliability of the charging device by preventing possible sticking of thermoplastic raw materials to be processed to the closure, which separates the loading device from the raw material processing plant.
Die gestellte Aufgabe wird dadurch gelöst, dass die Beschickungseinrichtung einer Anlage zur Verarbeitung von kohlenstoffhaltigen Rohstoffen in Form eines an der Anlage befestigten vertikalen Fallrohres ausgeführt ist und drei Kammern in einer Reihe unter- einander enthält, und zwar die Beschickungskammer und zwei sich nach unten erwei- ternde abdichtbare Kammern, wobei die Kammern voneinander und von der Anlage mit angetriebenen Verschlüssen getrennt sind; einen Gaszug mit Gaszwangszirkulation, in dessen Kreis ein Gaskϋhler installiert ist, und dessen Ein- und Austrittsquerschnitte mit Verschlüssen versehen und an der Seitenfläche der mittleren Kammer der Einrichtung angeordnet sind. Die abdichtbaren Kammern sind als Kegel- oder Pyramidenstumpf ausgeführt, und der Ein- und der Austrittsquerschnitt des Gaszuges liegen dementsprechend im oberen und unteren Bereich der mittleren Kammer der Einrichtung. Bei kegelförmiger Ausführung der abdichtbaren Kammern liegen Ein- und Austrittsquerschnitt des Gaszuges tangential zur Kammer.This object is achieved in that the charging device of a plant for processing carbonaceous raw materials is designed in the form of a vertical downpipe attached to the plant and contains three chambers in a row with one another, namely the charging chamber and two downwards. tempering sealable chambers, wherein the chambers are separated from each other and from the system with driven shutters; a throttle cable with forced gas circulation, in the circle of a gas cooler is installed, and its inlet and outlet cross-sections provided with closures and arranged on the side surface of the central chamber of the device. The sealable chambers are designed as a conical or truncated pyramid, and the inlet and the outlet cross-section of the throttle cable are accordingly in the upper and lower regions of the middle chamber of the device. In conical design of the sealable chambers are inlet and outlet cross section of the gas flue tangent to the chamber.
Werden die abdichtbaren Kammern so ausgeführt, dass sie sich nach unten verbreitern, so kann die Kontaktfläche der zu verarbeitenden Rohstoffe mit den Kammerwänden verringert werden, da die Rohstoffe beim Fall aus der Beschickungskammer in die mittlere abdichtbare Kammer die Form einer sich nach unten verbreiternden Säule anneh- men. Die Rohstoffe bekommen nur mit dem erhitzten Verschluss Kontakt. Es vermindert sich die Wahrscheinlichkeit des Festklebens der zu verarbeitenden Rohstoffe an den erhitzten Kammerwänden. Auch ist ein ungehinderter Durchgang der Rohstoffe durch die Beschickungseinrichtung gewährleistet, was die Betriebszuverlässigkeit erhöht, im Gegensatz z.B. zum Prototyp, bei dem der sich nach unten vermindernde Querschnitt der Beschickungskammer zu einer Verstopfung der Austrittsöffnung führen kann, was sich in der Praxis zeigt.When the sealable chambers are made to widen downwardly, the contact area of the raw materials to be processed with the chamber walls can be reduced because the raw materials, when falling from the feed chamber into the middle sealable chamber, take the form of a downwardly widening column - men. The raw materials only get in contact with the heated cap. It reduces the likelihood of sticking the raw materials to be processed on the heated chamber walls. Also, unimpeded passage of raw materials through the feeder is ensured, which increases operational reliability, in contrast to e.g. to the prototype, in which the downwardly decreasing cross-section of the feed chamber can lead to a blockage of the outlet opening, which is shown in practice.
Die Ausstattung der Einrichtung mit einem Gaszug mit Gaszwangszirkulation, in dessen Kreis ein Gaskühler installiert ist, gewährleistet die Möglichkeit des Haltens der erforder- liehen Temperatur in der mittleren Kammer der Einrichtung, bei der kein Schmelzen der Rohstoffe und deren Festkleben an den Konstruktionselementen der Einrichtung eintritt, wodurch die Betriebszuverlässigkeit erhöht wird. Die Anordnung des Austrittsquerschnitts des Gaszuges im unteren Teil der Kammer ermöglicht eine optimale Ausnutzung der Energie des gekühlten Gases für die Kühlung des Kontaktbereiches von Rohstoffen und den Teilen der Einrichtung, hauptsächlich im Bereich des Verschlusses. Das in der Kammer erhitzte Gas wird über den Eintrittsquerschnitt des Gaszuges, der im oberen Teil der Kammer liegt, zum Zirkulieren gebracht. Die Anordnung von Klappen im Ein- und Austrittsabschnitt des Gaszuges ermöglicht eine Unterbrechung der Gaszirkulation für die Zeit des Öffnens der Verschlüsse, welche die untere Kammer von der Kammer der Anlage und die mittlere und die untere Kammer bei der Beschickung der Anlage mit der nächstfolgenden Rohstoffcharge trennen. Die heißen und chemisch aggressiven Gase aus der Anlage gelangen nicht in den Gaszug, sie kondensieren nicht an den Wänden des Gaszuges, wodurch die Betriebszuverlässigkeit erhöht wird.The equipment of the device with a throttle cable with forced gas circulation, in the circle of a gas cooler is installed, ensures the possibility of holding the necessary lent temperature in the middle chamber of the device in which no melting of the raw materials and their sticking to the structural elements of the device occurs , which increases operational reliability. The arrangement of the exit section of the throttle cable in the lower part of the chamber allows optimum utilization of the energy of the cooled gas for the cooling of the contact area of raw materials and parts of the device, mainly in the area of the closure. The gas heated in the chamber is circulated through the inlet section of the throttle cable located in the upper part of the chamber. The arrangement of flaps in the inlet and outlet portions of the throttle cable allows for interruption of the gas circulation for the time of opening the shutters, which the lower chamber of the chamber separate the system and the middle and lower chambers with the next raw material batch when loading the system. The hot and chemically aggressive gases from the system do not get into the throttle cable, they do not condense on the walls of the throttle cable, whereby the operational reliability is increased.
In der Praxis werden Gehäuse und Verschlüsse von Beschickungseinrichtungen aus verfügbarem, gegen erhöhte Temperaturen und aggressive Medien beständigem Werkstoff gefertigt. Da die Wärmeleitfähigkeit der Luft beträchtlich unter der von Metall liegt, fungiert die untere Kammer der Einrichtung als Wärmedämmungspuffer zwischen der Kammer der Anlage und der mittleren Schleusenkammer der Einrichtung. Es vermindert sich der Energieaufwand für das Halten der für die Verhinderung des Festklebens der Rohstoffe in der mittleren Kammer der Einrichtung benötigten Temperatur. Es vermindert sich die Wahrscheinlichkeit der Kondensation der Produkte der zu verarbeitenden Rohstoffe an der Oberfläche des Verschlusses, der die Kammer der Anlage von der Beschickungseinrichtung trennt.In practice, casings and closures of feeders are manufactured from available material resistant to elevated temperatures and aggressive media. Since the thermal conductivity of the air is considerably lower than that of metal, the lower chamber of the device acts as a thermal buffer between the chamber of the plant and the central lock chamber of the device. It reduces the energy required to hold the temperature needed to prevent sticking of the raw materials in the center chamber of the device. It reduces the likelihood of condensation of the products of the raw materials to be processed on the surface of the closure, which separates the chamber of the plant from the feeder.
Die Anordnung von Ein- und Austrittsquerschnitt des Gaszuges tangential zu den Wänden der mittleren Kammer, die als Kegelstumpf ausgeführt ist, gewährleistet eine gleich- mäßige Umströmung der Rohstoffe durch den gekühlten Gasstrom, ohne dass sich Stauzonen bilden, wodurch die Wahrscheinlichkeit des Festklebens der Rohstoffe abnimmt.The arrangement of inlet and outlet cross section of the gas flue tangent to the walls of the middle chamber, which is designed as a truncated cone, ensures a uniform flow around the raw materials through the cooled gas flow, without the formation of congestion zones, whereby the likelihood of sticking of the raw materials decreases ,
Somit ermöglicht die Nutzung der Erfindung eine Erhöhung der Betriebszuverlässigkeit der Beschickungseinrichtung durch Verhinderung des Festklebens der Rohstoffe an deren Arbeitsflächen. Das Vorhandensein von drei Verschlüssen dichtet die Kammer der Verarbeitungsanlage zuverlässig ab, eine Emission toxischer Stoffe wird ausgeschlossen, und in der Kammer wird das erforderliche verfahrenstechnische Regime gehalten.Thus, the use of the invention enables an increase in the operational reliability of the feeder by preventing the sticking of the raw materials to their work surfaces. The presence of three closures reliably seals the processing equipment chamber, eliminating toxic emissions, and maintaining the required process regime in the chamber.

In the same way, the charging chamber 3 can be executed. The closures 6, 7 and 8 can be designed as slides, flaps, etc. The device can be equipped with a control panel, on whose signals the shutters 6, 7 and 8 and the flaps 13 and 14 are moved.

Ist die Einfüllung der nächsten Rohstoffcharge in die Verarbeitungsanlage 2 erforderlich, werden die Klappen 13 und 14 geschlossen und die Verschlüsse 8 und 7 geöffnet; die Rohstoffe gelangen daraufhin aus der Kammer 4 durch die Kammer 5 in die Anlage 2. Da der Prozess des Entladens der Rohstoffe aus der Kammer 4 in die Anlage 2 schnell abläuft, vermag der Verschluss 7 nicht, sich auf die Schmelztemperatur der Rohstoffkomponenten zu erhitzen, was deren Festkleben hauptsächlich am Verschluss 7 verhindert.
