Description
Die Erfindung betrifft ein Verfahren zur Steuerung oder Regelung eines Prozeßablaufs für ein Schüttgut nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for controlling or regulating a Process flow for a bulk material according to the preamble of claim 1.
Derartige Verfahren dienen insbesondere bei der Müllverbrennung zur Er reichung eines optimalen Wirkungsgrads. Dabei wird zur Steuerung und Re gelung der Müllverbrennung die Dampfleistung als Maß für den Müllmas senstrom und der Restsauerstoffgehalt im Rauchgas für den Gesamtverbren nungsluftbedarf herangezogen. Die sich daraus ergebende Prozeßführung ist jedoch weitgehend statistischer Art, weil der Brennstoff Müll starken Dichten- und Heizwertschwankungen unterliegt. Abweichungen von der Ausle gung der Anlage und einem damit verbundenen schlechten Wirkungsgrad sind daher unvermeidbar.Such methods are used in particular for waste incineration achieving optimal efficiency. It is used for control and re of waste incineration, the steam output as a measure of the amount of waste current and the residual oxygen content in the flue gas for total combustion air supply requirements. The resulting litigation is however largely statistical in nature because the fuel is strong waste Density and calorific value fluctuations. Deviations from the Ausle system and the associated poor efficiency therefore inevitable.
Aufgabe der Erfindung ist es daher eine Verfahren nach dem Oberbegriff des Anspruchs 1 zu schaffen, das einen Verfahrensablauf mit einem hohen Wirkungsgrad erlaubt.The object of the invention is therefore a method according to the preamble of claim 1 to create a process flow with a high Efficiency allowed.
Diese Aufgabe wird gemäß dem kennzeichnenden Teil des Anspruchs 1 gelöst. This object is achieved in accordance with the characterizing part of claim 1.
Hierdurch wird ein Verfahren geschaffen, daß unabhängig von stark schwan kendem Schüttgewicht und Qualität eine optimale Prozeßführung erlaubt.This creates a process that is independent of strong swans low bulk density and quality allows optimal process control.
Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further embodiments of the invention are the following description and the subclaims.
Die Erfindung wird nachstehend anhand der beigefügten Abbildungen näher beschrieben.The invention will now be described with reference to the accompanying figures described.
Fig. 1 zeigt schematisch und teilweise eine Müllverbrennungsanlage, deren Prozeßablauf mit dem erfindungsgemäßen Verfahren steuer- oder regelbar ist, Fig. 1 shows schematically and partially a waste incinerator, the process flow control with the inventive method or regulated,
Fig. 2 und 3 zeigen den Druckverlauf eines Fördermittels in Abhän gigkeit des Zeitverlaufs eines Austragsvorganges für einen lockeren und einen kompakten Müll. Fig. 2 and 3 show the pressure profile of a conveyor in depen dependence of the time course of a Austragsvorganges for a soft and compact garbage.
Die Erfindung betrifft ein Verfahren zur Steuerung oder Regelung eines Prozeßablaufs für ein Schüttgut 1, insbesondere Müll, bei dem das Schütt gut 1 zunächst in einen Vorratsbehälter 2 eingebracht wird und von dort in eine Prozeßkammer 3 befördert wird. Vorzugsweise handelt es sich bei dem Prozeßablauf um eine Abfallverbrennung, insbesondere eine Hausmüll verbrennung, wobei der Vorratsbehälter 2 den Müllaufgabetrichter und die Prozeßkammer 3 die Brennkammer bilden.The invention relates to a method for control of a process flow for a bulk material 1, in particular garbage, wherein the bulk is well initially introduced into a storage tank 2 1 and is conveyed from there into a process chamber. 3 Preferably, the process is a waste incineration, in particular domestic waste incineration, the storage container 2 forming the refuse hopper and the process chamber 3 forming the combustion chamber.
Zum Austragen des Schüttguts 1 aus dem Vorratsbehälter 2 in die Prozeß kammer 3 für einen anschließenden Prozeßschritt, z. B. Verbrennung des Schüttguts, ist ein Fördermittel vorgesehen, das vorzugsweise als Förder stößel 4, gemäß Fig. 1, oder ein Förderband ausgebildet ist. Das Förder mittel bewegt sich während eines Austragsvorganges mit einem regelbaren Hub für eine variable Einstellung des Schubweges. Darüberhinaus ist die Schubgeschwindigkeit variabel einstellbar. Angetrieben wird das Förder mittel über eine Hydraulikpumpe 5. Ebenso kann ein pneumatisches Antriebs element vorgesehen sein. To discharge the bulk material 1 from the reservoir 2 in the process chamber 3 for a subsequent process step, for. B. combustion of the bulk material, a funding is provided, which is preferably designed as a tappet 4 , as shown in FIG. 1, or a conveyor belt. The funding moves during a discharge process with an adjustable stroke for a variable adjustment of the thrust path. In addition, the thrust speed is variably adjustable. The funding is driven by a hydraulic pump 5 . A pneumatic drive element can also be provided.
Zur Steuerung und Regelung des Prozeßablaufs (z. B. Abfallverbrennung) ist ein Verfahren vorgesehen, in das als Führungsgrößen die Qualität und Dichte des Schüttguts 1 eingehen. Zur Bestimmung der Qualität und Dichte des Schüttguts 1 wird der für einen Austragsvorgang notwendige Kraftver lauf des Fördermittels gemessen. Gemäß Fig. 1 dient hierzu ein Druckauf nehmer 6. Der Kraftverlauf wird folglich über einen Druckverlauf gemessen und einem Regler 7 zugeführt. Dieser Regel 7 besitzt eine Signalstrecke 8 zu einer Einrichtung zur Einstellung des Massenstroms, d. h. Einstellung des Schubweges und/oder der Schubgeschwindigkeit, und eine Signalstrecke 9 für eine oder mehrere prozeßrelevante Führungsgrößen eines Prozeß schritts. Wird als Fördermittel ein Förderband verwendet, dient zur Er mittlung des Kraftverlaufes die aufgenommene Leistung des Antriebs für das Fördermittel.A method is provided for controlling and regulating the process sequence (e.g. waste incineration), in which the quality and density of the bulk material 1 are included as reference variables. To determine the quality and density of the bulk material 1 , the necessary Kraftver course of the funding is measured for a discharge process. Referring to FIG. 1 for this purpose a pressure to slave 6 is used. The force curve is consequently measured via a pressure curve and fed to a controller 7 . This rule 7 has a signal path 8 to a device for setting the mass flow, ie setting the thrust path and / or the thrust speed, and a signal path 9 for one or more process-relevant command variables of a process step. If a conveyor belt is used as the funding, the power consumed by the drive for the funding is used to determine the force profile.
Fig. 2 zeigt den Kraftverlauf (Druck oder Leistung) für einen Förderzy klus (Austragung) bei kleinem Schüttgewicht, was einem lockeren Aufgabe gut entspricht. Abschnitt a entspricht der Verdichtungsphase und Ab schnitt b der Förderphase. Die Gesamtfläche c entspricht der Summe aus Verdichtungs- und Förderarbeit und ist ein Maß für die Förderung des Schüttgut. Die Steigung d ist ein Maß für das Schüttgewicht. Der sich er gebende Druck- oder Leistungsgradientenverlauf dient als Steuerungs- oder Regelungsgröße des Prozeßschritts (Verbrennung). Fig. 2 shows the force curve (pressure or power) for a delivery cycle (discharge) with a small bulk weight, which corresponds well to a loose task. Section a corresponds to the compression phase and section b corresponds to the production phase. The total area c corresponds to the sum of compaction and conveying work and is a measure for the conveyance of the bulk material. The slope d is a measure of the bulk weight. The resulting pressure or power gradient curve serves as a control variable of the process step (combustion).
Fig. 3 zeigt einen entsprechenden Kraftverlauf (Druck oder Leistung) bei einem Schüttgut mit hohem Schüttgewicht, was einem kompakten Aufgabegut entspricht. Fig. 3 shows a corresponding curve force (pressure or power) with a bulk material with high bulk density, which corresponds to a compact feed.
