Description

Verfanren und Anlage zum Reinigen von verschmutzten Abgasen F Ver Anren and plant for cleaning of contaminated gases

Die Erfindung betrifft ein Verfahren und eine Anlage zum Reinigen von verschmutzten Abgasen mittels regenerativer ther- mischer Nacnverbrennung in Reaktionsbehaltem, die Warmespei¬ chermaterial enthalten und mit einer Brennkammer m Verbindung stehen.The invention relates to a method and a system for cleaning contaminated exhaust gases by means of regenerative thermal afterburning in reaction vessels which contain heat storage material and are connected to a combustion chamber.

Regenerative thermische Nachverbrennungsanlagen arbeiten allgemein im Pendelverfahren mit zwei, drei oder auch mehr Kam- mern, die mit Warmespeichermasse gefüllt sind. Die Eintritts¬ temperatur des Rohgases bewegt sich dabei üblicherweise zwi¬ schen 20-150°C, die Brennkammertemperatur zwischen 700-900°C und die Austrittstemperatur liegt 20-50°C über der Eintritts¬ temperatur. Durch die Pendelung wird im Normalfall etwa 95% der erforderlichen Wärmeenergie über die Speichermasse ruckge- wonneπ, so daß nur mehr ein geringer Restenergiebedarf für die Aufrechterhaltung des Temperaturniveaus der Brennkammer erfor¬ derlich ist. Heute übliche Anlagen sind entweder mit kerami¬ schen Schuttkorpern, sogenannten Satteln, oder auch mit waben- formigen Speichermassen bestuckt. Durch normalerweise im Rohgas enthaltene Feststoffe, wie Staub, Aerosole aber auch Flugasche, kommt es im Betrieb zu einer Verlegung des Eintrittsbereiches der Speichermasse. Dadurch steigt der Druckverlust und das Schutt- oder Wabenbett verstopft nach und nach. Diesem Problem konnte bisher nur durch eine entsprechend aufwendige Vorreini¬ gung αes Rohgases begegnet werden. Ferner besteht bei den be¬ kannter. Verfahren und Anlagen das Problem, daß im Heißbereich Schmelzaschen auftreten, die nach und nach zu einer Verstopfung fuhren. Die Erfindung zielt darauf ab, ein Verfahren sowie eine zu dessen Durchfuhrung bestimmte Anlage zu schaffen, mit denen die vorstehend geschilderten Probleme vermieden werden. Das erfm¬ dungsgemäße Verfahren zeichnet sich dadurch aus, daß das Spei- chermaterial aus Schuttmaterial gebildet ist, das aus den Reak- tionsbehaltern abgezogen, extern gereinigt und den Reaktionsbe¬ haltem über die Brennkammer wieder zugeführt wird, so daß em geschlossener Speichermateπal-Kreislauf entsteht. Vorzugsweise werden als Schuttmaterial kornige keramische, mineralische oder metallische Speichermassen, insbesondere mit einer Korngroße von 3-30 mm Korndurchmesser, verwendet.Regenerative thermal post-combustion plants generally operate in a pendulum process with two, three or even more chambers that are filled with heat storage mass. The inlet temperature of the raw gas usually ranges between 20-150 ° C, the combustion chamber temperature between 700-900 ° C and the outlet temperature is 20-50 ° C above the inlet temperature. The oscillation normally recovers about 95% of the required thermal energy via the storage mass, so that only a small amount of residual energy is required to maintain the temperature level of the combustion chamber. Systems common today are either equipped with ceramic rubble bodies, so-called saddles, or also with honeycomb-shaped storage masses. Solids normally contained in the raw gas, such as dust, aerosols, but also fly ash, cause the storage area's entry area to be moved during operation. This increases the pressure loss and gradually clogs the bed of debris or honeycomb. So far, this problem could only be countered by a correspondingly complex pre-cleaning of the raw gas. Furthermore, there are known ones. Processes and systems the problem that hot ashes occur in the hot area, which gradually lead to constipation. The invention aims to provide a method and a system intended for carrying it out, with which the problems described above are avoided. The method according to the invention is characterized in that the storage material is formed from rubble material, which is drawn off from the reaction vessels, cleaned externally and fed back into the reaction containers via the combustion chamber, so that a closed storage material circuit is created . Grainy ceramic, mineral or metallic storage masses, in particular with a grain size of 3-30 mm grain diameter, are preferably used as rubble material.

Durch die Erfindung wird erreicht, daß im Vergleich zur bisher üblichen Vorreinigung und thermischen Nachverbrennung der Gesamtinvestitionsbedarf des Verfahrens reduziert und zu¬ gleich die Betriebssicherheit verbessert werden.The result of the invention is that the total investment required for the process is reduced in comparison to the previously usual pre-cleaning and thermal afterburning, and at the same time the operational safety is improved.

Eine zur Durchfuhrung des erfindungsgemaßen Verfahrens be¬ stimmte Anlage mit Reaktionsbehaltem, die Warmespeichermateri- al enthalten und über eine Brennkammer miteinander m Verbin¬ dung stehen, ist dadurch gekennzeichnet, daß jeder Reaktionsbe- halter mit Schuttmaterial gefüllt ist und an einem Ende einen Schuttmaterial-Auslaß aufweist, über welchen das Schuttmaterial abziehbar und über eine Reinigungsvorrichtung, vorzugsweise eine Entaschungsvorrichtung, der Brennkammer im Kreislauf wieder zufuhrbar ist.A plant intended for carrying out the method according to the invention with reaction containers which contain heat storage material and are connected to one another via a combustion chamber is characterized in that each reaction container is filled with rubble material and at one end a rubble material outlet has, over which the rubble material can be removed and fed to the combustion chamber in the circuit via a cleaning device, preferably a deashing device.

Nach einem weiteren Erfindungsmerkmai sind zwei parallele oder ein Vielfaches von zwei parallelen Reaktionsbehaltem vor¬ gesehen, die mit einem Speicherbehalter zum Auffangen von Um- schaltspitzen in Verbindung setzbar sind, wobei der Speicherbe- halter mit der Rohgasleitung in Verbindung setzbar ist.According to a further feature of the invention, two parallel or a multiple of two parallel reaction vessels are provided, which can be connected to a storage tank for collecting changeover peaks, the storage tank being connectable to the raw gas line.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend un¬ ter Bezugnahme auf die schematische Zeichnung naher erläutert.An embodiment of the invention is explained in more detail below with reference to the schematic drawing.

Die gezeigte Anlage weist einen Reaktor 1 mit zwei Reakti- onsbehaltern 1' auf, die über eine Brennkammer 2 miteinander in Verbindung stehen. Das von einer Rohgasleitung L zugefuhrte Rohgas tritt über em automatisch geschaltetes Absperrorgan 3 in jeweils einen der Reaktionsbehalter 1' em, die mit einer abrieb- und wechseltemperaturbestandigen Speichermasse m Form eines Schuttbettes 1" gefüllt ist. Dort nimmt das Rohgas Wärme¬ energie aus der Speichermasse auf, wobei sich die Temperatur bei der Durchstromung auf die Temperatur der Brennkammer 2 er¬ höht. Ein Stutzbrenner 4 halt das Temperaturniveau der Brenn¬ kammer 2 auf einem eingestellten Wert von z.B. 700-900°C kon- stant.The plant shown has a reactor 1 with two reaction vessels 1 ′ which are connected to one another via a combustion chamber 2. The raw gas supplied by a raw gas line L enters via an automatically switched shut-off device 3 in each of the reaction vessels 1 'em, which is filled with a storage mass in the form of a rubble bed 1 "which is resistant to abrasion and changing temperatures. There the raw gas takes thermal energy from the storage mass , whereby the temperature during the flow increases to the temperature of the combustion chamber 2. A support burner 4 keeps the temperature level of the combustion chamber 2 at a set value of, for example, 700-900 ° C.

Bei Durchströmen des zweiten Reaktionsbehalters l1 erfolgt die Wärmeabgabe an dessen Speichermasse, wobei das von den oxy¬ dierbaren Inhaltsstoffen befreite Gas sich entsprechend ab- kühlt. Über em jedem Reaktionsbehalter zugeordnetes Ausgangs- absperrorgan 5 gelangt danach das Reingas in eme Reingaslei- tung L' . Wird eme bestimmte einstellbare Temperaturdifferenz von z.B. 20-50°C erreicht, so werden die Absperrorgane 3 und 5 automatisch umgeschaltet, so daß sich der Warmeübertragungsvor- gang umkehrt und die Anlage pendelt. Übliche Umschaltzelten liegen bei 2-4 mm.When flowing through the second reaction vessel 1 1 , the heat is given off to its storage mass, the gas freed from the oxidizable constituents correspondingly cools. The clean gas then reaches the clean gas line L 'via an outlet shut-off device 5 assigned to each reaction vessel. If a certain adjustable temperature difference of, for example, 20-50 ° C. is reached, the shut-off devices 3 and 5 are automatically switched over so that the heat transfer process is reversed and the system oscillates. Usual switching tents are 2-4 mm.

Unmittelbar nach dem Umschalten tritt im Reingas eme Um- schaltspitze auf, weil das im Einstrombereich befindliche unbe- handelte Rohgas wegen der niedrigen Temperatur noch nicht oxy¬ diert ist. Eme oxydative Reaktion tritt im allgemeinen erst ab etwa 400°C, d.h. im oberen Drittel der Speichermasse auf. Zur Verminderung der Umschaltspitze wird die teilbehandelte und verdünnte Rongasspitze über automatisch geschaltete Absperr- organe 6 in einen Spitzenaufnahmebehalter 1 umgeleitet und in die Rohgasleitung L über em Geblase 8 ruckgefordert. Eine Spitzenglattung von 80-90% im Verhältnis zum Reingaswert wird dadurch erreicht.Immediately after switching occurs in the clean gas eme switchover tip because the un- contained in the inflow region acted raw gas is diert because of the low temperature is not oxy ¬. An oxidative reaction generally only occurs from around 400 ° C, ie in the upper third of the storage mass. To reduce the changeover peak, the partially treated and diluted Rongass tip is diverted via automatically switched shut-off elements 6 into a tip holder 1 and reclaimed into the raw gas line L via a blower 8. A peak smoothing of 80-90% in relation to the clean gas value is achieved.

Em Remgasventilator 9 erzeugt den erforderlichen Unter- druck oder Überdruck, um die Durchstromung zu ermöglichen. Das Schuttmaterial 1" wird aus dem Reaktionsbehalter an dessen unterem Ende über Austrageinrichtungen 10, z.B. über em Schleusensystem, Zellenrader oder Schnecken, abgezogen und durch em allgemein mit 11 bezeichnetes Transportsystem, wie Schnecke, Becherwerk oder Rohrkettenforderer erfaßt und einer Reinigungseinheit 12, wie einem Entaschungssieb, zugeführt. Hier wird das Material m einer Siebtrommel von anhaftendem Femmaterial gereinigt, welches durch das Sieb nach unten aus¬ fallt und ausgetragen wird. Danach gelangt das so gereinigte Schuttmaterial 1" zur Oberseite der Brennkammer 2, von wo es über Absperrorgane 13 oder ein Schleusensystem m die Brenn¬ kammer zugegeben wird.A residual gas fan 9 generates the required underpressure or overpressure in order to enable the throughflow. The rubble material 1 "is withdrawn from the reaction container at its lower end via discharge devices 10, for example via a lock system, cellular wheel or screws, and is detected by a transport system, generally designated 11, such as a screw, bucket elevator or pipe chain conveyor and a cleaning unit 12, such as a deashing screen Here, the material is cleaned in a sieve drum from adhering fem material, which falls down through the sieve and is discharged Lock system m the combustion chamber is added.

Damit ist der Schuttmaterialkreislauf geschlossen, Verlu¬ ste an Abrieb werden durch eine Neumaterialzugabe ausgeglichen. Es versteht sicn, daß das vorstehend geschilderte Ausfüh¬ rungsbeispiel im Rahmen des allgemeinen Erfindungsgedankens verschiedentlich abgewandelt werden kann, insbesondere was das Transportsystem für das Schuttmaterial, die Art des Schuttmate- rials und die einzelnen Absperrorgane betrifft.This closes the debris cycle, and losses in abrasion are compensated for by adding new material. It goes without saying that the exemplary embodiment described above can be modified in various ways within the scope of the general inventive concept, in particular what that Transport system for the rubble material, the type of rubble material and the individual shut-off devices.

Wahrend bei dem dargestellten und beschriebenen Ausfuh¬ rungsbeispiel em Reaktor mit zwei parallelen Reaktionsbehal¬ tem verwendet wird, kann im Rahmen der Erfindung auch em Vielfaches von zwei Behaltern vorgesehen werden. While a reactor with two parallel reaction vessels is used in the illustrated and described embodiment, a multiple of two vessels can also be provided in the context of the invention.
