Abstract
Description
Beschreibung und Erläuterung zur Zusatz-PatentanmeldungDescription and explanation of the additional patent application
Trocken-Entschwefelungs-Verfahren lt Zusatz zu P 29 35 464.1 Es ist bekannt, vorzugsweise bei Braunkohlenkraftwerken, das Trocken-Additiv, z.B. Kalk oder Dolomit vermischt mit dem Brennstoff oder auch allein, dem Feuerungsraum zuzuführen. Dry desulphurisation process according to addendum to P 29 35 464.1 It is known, preferably in lignite power stations, the dry additive, e.g. lime or dolomite mixed with the fuel or alone to be fed to the furnace.
Hierbei werden Entschwefelungsgrade von 60 % max.Desulfurization degrees of 60% max.
erzielt.achieved.
Diese Entschwefelungsrate reicht in der Regel bei sehr schwefelhaltiger Kohle nicht aus, um die vom Gesetzgeber vorgeschriebenen Reingaswerte zu erzielen.This desulfurization rate is usually sufficient for those with a very high sulfur content Coal is not used in order to achieve the clean gas values prescribed by the legislator.
Aus diesem Grunde wird vorgeschlagen, hinter dem Elektrofilter eine Kontaktstrecke bzw. eine Reaktorstrecke nachzuschalten, in der das trockene Additiv, das zur Rauchgasentschwefelung dienen soll, aufgegeben wird, und hinter dieser Reaktor- und Kontaktstreckentechnologie ist vorzugsweise ein Gewebefilter entsprechend der Patentanmeldung P 29 35 464.1 nachgeschaltet, so daß die hinter dem Elektrofilter auftretende Restimmission von z.B. 40 % mit dem Frischkalk bis zu 80 % gebunden werden kann, und der nicht reagierte Kalk oder Dolomit staub mit dem reagierten Additiv aus dem Gewebefilter der Feuerung oder dem Brennstoff - wie bekannt - zugeführt wird.For this reason, it is suggested that a Downstream contact section or a reactor section in which the dry additive, the to serve for flue gas desulfurization, is abandoned, and behind this reactor and contact path technology is preferably a fabric filter according to FIG Patent application P 29 35 464.1 downstream, so that the behind the electrostatic precipitator Any residual immission of e.g. 40% bound with the fresh lime up to 80% can be, and the unreacted lime or dolomite dust with the reacted Additive from the fabric filter of the furnace or the fuel - as known - supplied will.
In der beiliegenden Zeichnung ist dargestellt: mit (1) der Kessel mit (2) der Elektrofilter mit (3) die Reaktor- und/oder Kontaktstrecke mit (4) der Gewebefilter - System nach P 29 35 464.1 mit (5) der dem Gewebefilter nachgeschaltete Ventilator mit (6) das Transportmittel, das den chemisorbierten und noch freien Kalk bzw. das noch freie Additiv aus dem Gewebefilterbereich ausschleust und mittels pneumatischer Förderereinrichtung (7) dem Brennstoff vor dem Kessel (8) oder dem Brennraum (9) im Kessel zuführt.The attached drawing shows: with (1) the boiler with (2) the electrostatic precipitator with (3) the reactor and / or contact path with (4) the Fabric filter system according to P 29 35 464.1 with (5) the one downstream of the fabric filter Fan with (6) the means of transport that chemisorbed and still free Lime or the still free Additive discharged from the fabric filter area and the fuel in front of the boiler by means of a pneumatic conveyor device (7) (8) or the combustion chamber (9) in the boiler.
Durch diese erfindungsgemäße Vorrichtung und Anordnung zur Durchführung des Verfahrens wird folgende trockene Entschwefelung möglich: Durch indirekte Beimischung des Additivs im Brennraum ca. 60 % Entschwefelung und bei z.B. auf dem S02-Gehalt des Rohgases 2-fach stöchiometrisch berechnet als Frischkalkzugabe zwischen Elektrofilter und Gewebefilter auf die verbleibenden restlichen 40 % ist ein Wirkungsgrad von 80 % erzielbar, d.h. 32 % Abscheidung bezogen auf den Ausgangswert des S02 , addiert zu 60 % ergibt 92 C/o theoretisch möglichen Wirkungsgrad.Through this inventive device and arrangement for implementation The following dry desulphurisation is possible with the process: Through indirect admixing of the additive in the combustion chamber approx. 60% desulphurisation and e.g. on the S02 content of the raw gas calculated twice stoichiometrically as the addition of fresh lime between the electrostatic precipitator and fabric filter on the remaining remaining 40% is an efficiency of 80% achievable, i.e. 32% separation based on the initial value of the S02, added 60% results in 92 C / o theoretically possible efficiency.
Es ist durchaus möglich, den stöchiometrischen Faktor zu senken, wenn diese 92 % nicht notwendig sind, auf z.B. 1,5-fach stöchiometrische Zugabe.It is entirely possible to lower the stoichiometric factor, though this 92% is not necessary, to e.g. 1.5 times the stoichiometric addition.
Jedoch, durch die erfindungsgemäße Zugabe des Frischkalks hinter dem Elektrofilter und nach dem Gebrauch im Gewebefilter, Zugabe in den Brennraum und/oder mit dem Brennstoff gemischt, wird diese wesentlich höhere Entschwefelungsrate erzielt.However, by adding the fresh lime according to the invention behind the Electrostatic precipitator and after use in the fabric filter, adding to the combustion chamber and / or mixed with the fuel, this much higher desulphurisation rate is achieved.
