Description
Die Erfindung betrifft ein Verfahren zur Kondensation von Schwelgasen aus der Abfallpyrolyse.The invention relates to a method for condensing carbonisation gases from waste pyrolysis.
Bei der Abfallpyrolyse wird stückiger Abfall in einem beheizten Schwelreaktor unter Luftabschluß thermisch zersetzt, wobei ein an Kohlenwasserstoffen reiches Schwelgas gebildet wird, das zu seiner Wiederverwendung als öl kondensiert werden muß.In waste pyrolysis, lumpy waste is thermally in a heated smoldering reactor with the exclusion of air decomposed, with the formation of a carbonization gas rich in hydrocarbons, which can be reused must be condensed as oil.
Aufgabe der Erfindung ist es, ein Verfahren zu schaffen, das eine effiziente Kühlung der anfallenden Schwelgase im Dauerbetrieb gestattet.The object of the invention is to create a method that efficiently cools the accumulating Smoldering gases permitted in continuous operation.
Diese Aufgabe wird erfindüngsgemäß dadurch gelöst, daß die bei der Pyrolyse anfallenden heißen Schwelgase durch einen Sprühschleier kondensierter Schwelgase geleitet werden, daß das dabei entstehende Schwelgaskondensat weiter abgekühlt und zum Teil zur Erzeugung des Sprühschleiers verwendet wird. Der Kühleffekt wird hierbei durch die ständige Verdampfung des Sprühschleiers erreicht. Die direkte Verdampfungskühlung bietet einen optimalen Wärmeaustausch und vermeidet Störungen, wie das Zusetzen von Wärmeaustauschflächen und dergleichen. Mit der nachfolgenden Abkühlung des Schwelgaskondensats wird die den heißen Schwelgasen entstammende Wärme aus dem Kondensat abgeführt und seine Verwendung als Kühlmittel ermöglicht.This object is achieved according to the invention in that the hot carbonization gases produced during pyrolysis be passed through a spray curtain of condensed carbonization gases that the resulting carbonization gas condensate is further cooled and is used in part to generate the spray curtain. The cooling effect is achieved by the constant evaporation of the spray curtain. The direct evaporative cooling offers an optimal heat exchange and avoids disturbances such as the clogging of heat exchange surfaces and the same. With the subsequent cooling of the carbonization gas condensate, the heat from the condensate and its use as a Coolant allows.
Gemäß einer bevorzugten Ausgestaltung der Erfindung wird das Schwelgaskondensat vor seiner Abkühlung in einem Wärmetauscher gefiltert. Ferner wird bevorzugt das bei der Kondensation des Schwelgases verbleibende Restgas in einer zweiten Kühlstufe zur Abscheidung restlichen Kondensats gekühlt, wobei die Kühlung in der zweiten Kühlstufe durch Tieftempera-ο türkühlung erfolgen kann. Zur Aerosolabscheidung wird bevorzugt, das Restgas nachfolgend zu filtern.According to a preferred embodiment of the invention, the carbonization gas condensate is released before it is cooled filtered in a heat exchanger. This is also preferred during the condensation of the carbonization gas remaining residual gas is cooled in a second cooling stage to separate the remaining condensate, the Cooling in the second cooling stage can take place through low temperature ο turkooling. For aerosol separation is preferred to filter the residual gas subsequently.
Eine bevorzugte Ausführungsform des erfindungsgemäßen Verfahrens wird im folgenden anhand der einzigen Figur der Zeichnung beschrieben.A preferred embodiment of the method according to the invention is described below with reference to FIG single figure of the drawing described.
Bei der Pyrolyse von stückigem Abfall in einem beheizten Reaktor anfallendes heißes Schwelgas einer Temperatur von rund 900 K wird von oben in einen Kühlturm 1 geleitet. Im Mantelbereich desselben befinden sich, ringförmig angeordnete, nach innen gerichtete Sprühdüsen 2. Die Sprühdüsen werden mit durch eine Pumpe 3 angefördertem gekühltem Kondensat, das in flüssigem Zustand vorliegt, über Zuleitungen von außerhalb des Kühlturms gespeist und das Kondensat so zu einem Flüssigkeitsschleier bzw. Sprühnebel im Inneren des Kühlturms 1 zerstäubt Der im Kühlturm stehende Flüssigkeitsschleier wird dabei von den heißen Schwelgasen durchströmt, wobei sich der Kühleffekt aus der ständigen Verdampfung des Flüssigkeitsschleiers ergibt. Das abgekühlte Schwelgas regnet aus und sammelt sich als Flüssigkeit im Sumpf 4 am Boden des Kühlturms 1. Diese Art der direkten Verdampfung bietet wegen der großen Oberfläche, die. der Flüssigkeitsschleier dem heißen Schwelgas bietet, einen optimalen Wärmeaustausch. Es gibt kein Zusetzen oder Verschmutzen von Wärmeaustauschflächen und keine Verstopfungsgefahr. Das Sumpfkondensat wird durch ein Filter 6 und von dort in einen etwa mit einem geschlossenen Kühlwasserkreislauf mit Luftkühler betriebenen Wärmeaustauscher 7 geleitet, wo es weiter abgekühlt und die den heißen Schwelgasen entstammende Wärme abgeführt wird.During the pyrolysis of lumpy waste in a heated reactor, hot carbonisation gas is a A temperature of around 900 K is passed into a cooling tower 1 from above. In the mantle area of the same there are inwardly directed spray nozzles 2 arranged in a ring. The spray nozzles are with cooled condensate conveyed by a pump 3, which is in a liquid state, via feed lines fed from outside the cooling tower and the condensate is thus converted into a liquid curtain or Spray mist inside the cooling tower 1 is atomized. The liquid curtain standing in the cooling tower is thereby flowed through by the hot smoldering gases, whereby the cooling effect results from the constant evaporation of the Liquid veil results. The cooled carbonization gas rains out and collects as a liquid in the sump 4 at the bottom of the cooling tower 1. This type of direct evaporation offers because of the large surface that. the liquid curtain offers the hot carbonization gas an optimal heat exchange. There is no clogging or soiling of heat exchange surfaces and no risk of clogging. The sump condensate is through a filter 6 and from there into one operated approximately with a closed cooling water circuit with an air cooler Heat exchanger 7 passed, where it is further cooled and the hot carbonization gases originating Heat is dissipated.
Das (z. B. auf 320 K) abgekühlte Kondensat wird zum Teil durch die Pumpe 3 über die Sprühdüsen 2 in den Kühlturm 1 zurückgepumpt, und überschüssiges Kondensat gegebenenfalls nach Abkühlung auf Umgebungstemperatur zur Weiterverwendung etwa in der chemischen Grundstoffindustrie abgeführt.The (z. B. to 320 K) cooled condensate is partly by the pump 3 via the spray nozzles 2 in the Cooling tower 1 pumped back, and excess condensate, if necessary after cooling to ambient temperature Discharged for further use, for example in the basic chemical industry.
Das bei der Kühlung im Kühlturm 1 vorwiegend aus Permanentgasen bestehende verbleibende Restgas wirdThe residual gas that remains during the cooling in the cooling tower 1, consisting predominantly of permanent gases, becomes
so in einer zweiten Kühlstufe zur Abscheidung von restlichem Kondensat ebenfalls weiter abgekühlt Bei dieser zweiten Kühlstufe kann es sich beispielsweise um eine elektrisch betriebene Tieftemperaturkühlstufe von ca. 250 K handeln. Dieser Kühlstufe ist gegebenenfalls zur Aerosolabscheidung ein Elektrofilter nachgeschaltet. so also cooled further in a second cooling stage to separate the remaining condensate this second cooling stage can, for example, be an electrically operated low-temperature cooling stage of trade approx. 250 K. An electrostatic precipitator may be connected downstream of this cooling stage for aerosol separation.
