Abstract
Description
Verfahren zur Verhinderung von Staub- und Geruchsbe-Procedure to prevent dust and odor pollution
lästigungen bei Abfallverbrennungsanlagen Die Erfindung betrifft ein Verfahren zur Verhin-derung von Staub- und Geruchsbelästigungen bei Abfallverbrennungsanlagen nach Patent ... (I>atentanmeldung P 27 31 339.9).nuisances in waste incineration plants The invention relates to a Process for the prevention of dust and odor nuisance in waste incineration plants according to patent ... (patent application P 27 31 339.9).
Für den Stand der Technik gilt das gleiche wie in der-Stammanmeldung beschrieben. Es hat sich jedoch- herausgestellt, daß insbesondere die Abscheidung der gasfö-rmigen Schadstoffe aus dem Verbrennungsprozeß durch Absorbtion an die Flugasche, insbesondere von in die Feuerung eingeblasenem zellulosehaltigen Feingut, geschehen kann, wodurch anschließend lediglich eine Abtrennung dieser Flugasche aus den Rauchgasen erforderlich wird.The same applies to the prior art as in the parent application described. However, it has been found that in particular the deposition the gaseous pollutants from the combustion process by absorption to the Fly ash, in particular from cellulose-containing fine material blown into the furnace, can happen, which then only separates this fly ash is required from the flue gases.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß insbesondere der zellulosehaltige Abfallanteil zumindest teilweise in ein staub- bzw. faserförmiges Feingut aufbereitet wird, daß dieses staub- bzw. faserförmige Feingut und anderes leicht flugfähiges Zerkleinerungsgut in die Feuerung über oder neben dem Rost für das grobkörnige Verbrennungsgut eingeblasen wird und daß dann die insbesondere von der Einblasfeuerung des zellulosehaltig#en Feingutes entstehende Flugasche nach Bindung der gasförmigen sauren Schadstoffe, wie Chlorwasserstoff oder Schwefeldioxyd, mittels elektrostatischer Filter, Gewebefilter oder Schüttschichtfilter ohne zusätzliche Rauchgasnaßwäsche abgeschieden wird.This object is achieved according to the invention in that in particular the cellulosic waste fraction at least partially into a dusty or fibrous one Fine material is processed that this dusty or fibrous fine material and others Easy to fly shredded material in the furnace above or next to the grate for the coarse-grained combustion material is blown in and that then the particular of the fly ash produced after the injection of the cellulose-containing fine material Binding of gaseous acidic pollutants such as hydrogen chloride or sulfur dioxide, by means of electrostatic filters, fabric filters or packed bed filters without additional Flue gas wet scrubbing is deposited.
Die Aufbereitung der insbesondere zellulosehaltigen Teile zu einem relativ feinen Faserstoff kann ganz oder teilweise in einem Rotte-Reaktor geschehen, in dem-nur schnell umsetzbare Bestandteile, wie Zucker, Stärke, Eiweißstoffe etc., teilweise oxidiert werden.The processing of the cellulose-containing parts into one relatively fine pulp can be completely or partially done in a Rotte reactor, in which-only quickly convertible components, such as sugar, starch, proteins, etc., be partially oxidized.
Zur Beschleunigung des Rotteprozesses einerseits und zur Entsorgung von Klärschlamm andererseits kann dem Abfallgemisch vor dem Rotteprozeß Klärschlamm zugesetzt werden.To accelerate the rotting process on the one hand and for disposal from sewage sludge on the other hand, sewage sludge can be added to the waste mixture before the rotting process can be added.
Während oder nach dem Rotteprozeß kann zweckmäßigerweise eine Trocknung vorgesehen werden.During or after the rotting process, drying can expediently take place are provided.
Wenn in den Abfallgemischen höhere Anteile Chlorwasserstoff oder Schwefeldioxyd bildende Bestandteile enthalten sind, wie PVC, Altgummi, schwefelhaltige Kohle, Masut etc., wird zweckmäßig zusätzlich zellulosehaltiges Feingut zugemischt und in die Feuerung eingeblasen.If the waste mixture contains higher proportions of hydrogen chloride or sulfur dioxide forming components are included, such as PVC, scrap rubber, sulphurous coal, Masut etc., cellulose-containing fine material is expediently added and added blown into the furnace.
Dieses zusätzliche zellulosehaltige Feingut kann beispielsweise Holzschleifstaub, Sägemehl, Fräs- und Hobelspäne der Holzindustrie oder auch zerkleinerte Rinde, zerkleinerte Pflanzenabfälle, wie Stroh, Zuckerrohr, Schilf, Baumwollstauden etc., sein.This additional cellulose-containing fine material can, for example, wood sanding dust, Sawdust, milling and shavings from the wood industry or also shredded bark, shredded Plant waste such as straw, sugar cane, reeds, cotton bushes, etc.
Zweckmäßig ist es, das zusätzliche zellulosehaltige Feingut getrennt von dem evtl. Rotteprozeß der im wesentlichen aus Hausmüll bestehenden Abfallstoffe aufzubereiten, z.B.It is useful to separate the additional cellulose-containing fine material of the possible rotting process of the waste materials consisting essentially of household waste to prepare, e.g.
lediglich zu zerkleinern und ggf. zu trocknen.only to be crushed and, if necessary, to be dried.
Gegenüber der Stammpatentanmeldung bedeutet das Verfahren gemäß dieser Zusatzanmeldung eine wesentliche apparative Vereinfachung dadurch, daß die gasförmigen Schadstoffe im Rauchgas bereits an die reichlich anfallende Flugasche aus eingeblasenem zellulosehaltigen Feingut gebunden wird und dann lediglich eine geeignete Abscheidung dieser Flugasche als einzige Rauchgasreinigung erforderlich ist. Eventuelle Wirbelschicht-Reaktoren mit alkalischem Feingut, z.B.Compared to the parent patent application, the method according to this means Additional application a significant simplification of the apparatus in that the gaseous Pollutants in the flue gas already to the abundant fly ash from blown Cellulose-containing fine material is bound and then only a suitable deposition this fly ash is required as the only flue gas cleaning. Any fluidized bed reactors with alkaline fine material, e.g.
Kalk, oder auch die relativ aufwendigen Schüttschichtfilter können nach diesem Verfahren entfallen, es genügt eine Rauchgasreinigung mit bekannten Elektrofiltern oder Gewebefiltern. Der Zusatz von zellulosehaltigem Feingut, insbesondere von staub- bzw. späneförmigen Abfällen der Holzindustrie, einerseits und die Erzeugung von zellulosehaltigem Fasermaterial aus Hausmüll durch einen leichten Rotteprozeß andererseits dürfte in den meisten Fällen der geringere Aufwand für die Gesamtanlage sein Die Einblasfeuerung des zellulosehaltigen Feingutes neben oder über der Rostfeuerung für das gleichmåßig zerkleinete Abfallgemisch bietet zudem den Vorteil einer weitgehenden Regelungsmö-glichkeit des Verbrennungsprozesses, da die Einblasfeuerung noch schneller eventuellen Wärmebedarfsschwankungen der Kesselanlage angepaßt werden kann als die Rostfeuerung.Lime, or even the relatively expensive packed bed filter can after this process is not necessary, a flue gas cleaning with known ones is sufficient Electrostatic precipitators or fabric filters. The addition of cellulosic fines, in particular of dusty or chip-like waste from the wood industry, on the one hand, and the production of cellulosic fiber material from household waste through a light Rotting process on the other hand, in most cases the less effort required for the entire system The injection furnace for the cellulose-containing fine material next to or above the grate furnace for the evenly shredded waste mixture also offers the advantage of an extensive The combustion process can be regulated, as the injection combustion is even faster possible heat demand fluctuations of the boiler system can be adapted as the Grate firing.
