Abstract
Description
Es ist bekannt, die durch nasse Rauchgasentschwefelungs anlagen (REA) gereinigten Rauchgase zunächst über Tropfen abscheider zu leiten. In diesen zum Entschwefelungsver fahren gehörenden Tropfenabscheidern erfolgt die Abtrennung häufig mehrstufig, so daß von Grob- und Feinabscheidern ge sprochen wird. Nach dem Passieren der Feinabscheider wer den die entschwefelten, feuchten Rauchgase durch Kanäle entweder Kaminen oder Kühltürmen zur Ableitung zugeführt. In den Rauchgaskanälen bilden sich an Wänden, Einbauten und Umlenkungen erneut Tropfen. Bevor die Rauchgase in den Kühltürmen freigesetzt werden, werden diese erneut über Tropfenabscheider geführt.It is known to be caused by wet flue gas desulfurization plants (REA) cleaned flue gases first by drops to manage the separator. In these for desulfurization The droplet separators belonging to the driver are separated often multi-stage, so that from coarse and fine separators is spoken. After passing the fine separator who the desulfurized, moist smoke gases through channels either chimneys or cooling towers are fed for discharge. In the flue gas ducts, internals form on the walls and redirection drops again. Before the flue gases come in the cooling towers are released, they will again guided over droplet separators.
Durch die DE 35 20 380 A1 ist ein Verfahren zur Lang zeitbestimmung und Dauerüberwachung des Schadstoffgehal tes von gasgetragenen Aerosolen von mit Flüssigkeitsbe standteilen bzw. -tröpfchen beladenen Abgasströmen hin ter Rauchwäschern von Großfeuerungen oder Müllverbrennungs anlagen, mit isokinetischer Teilentnahme der Probe aus dem Aerosolstrom mittels Unterdrucks und mindestens teilweiser Beheizung der Entnahmesonde mit folgenden Verfahrensschrit ten bekannt:DE 35 20 380 A1 is a method for Lang Time determination and continuous monitoring of the pollutant content tes of gas-borne aerosols with liquids components or droplets loaded exhaust gas flows smoke washers from large combustion plants or waste incineration plants systems with isokinetic partial sampling of the Aerosol flow by means of negative pressure and at least partially Heating the sampling probe with the following process steps known:
- a) Verdampfen der Flüssigkeit in den Tröpfchen der abge saugten Aerosole durch weiteres Aufheizen über die Temperatur z. B. der Rauchgase hinaus,a) Evaporation of the liquid in the droplets of the abge sucked aerosols by further heating over the Temperature z. B. the flue gases,
- b) kontinuierliches Abscheiden der gröberen Feststoffe, z. B. in einem Gaszyklon mit kontinuierlichem Ausschleu sen der abgeschiedenen Feststoffe, z. B. durch eine Takt schleuse und Überführen derselben in Sammelbehälter,b) continuous separation of the coarser solids, e.g. B. in a gas cyclone with continuous discharge sen the separated solids, e.g. B. by a clock sluice and transfer of the same into collecting containers,
- c) kontinuierliches Abscheiden der Dämpfe durch Konden sation mit anschließenden Gaswaschstufen,c) continuous separation of the vapors by condensates station with subsequent gas washing stages,
- d) Bestimmen der Schadstoffverteilung des Abgasstromes durch Eichmessungen des aus den Sammelbehältern, aus den Kondensations- und den Waschstufen gewonnenen Probenmaterials,d) determining the pollutant distribution of the exhaust gas flow by calibration measurements of the from the collection containers the condensation and washing stages Sample material,
- e) Beschränkung der kontinuierlichen Schadstoffabtren nung nach Bestimmung der Schadstoffverteilung jeweils auf die Abscheidung der Feststoffe oder auf die konti nuierliche Abscheidung der Dämpfe oder/und die Gas waschstufen und Bilanzierung derselben.e) Limitation of continuous pollutant removal after determination of the pollutant distribution on the separation of the solids or on the conti Nuclear separation of the vapors and / or the gas washing stages and accounting for the same.
Es wurde überraschenderweise gefunden, daß die in den am Ende der Rauchgaskanäle befindlichen Tropfenabscheidern anfallenden Spülwässer und/oder Kondensate zur Überwachung der Rauchgasentschwefelungsanlagen herangezogen werden kön nen.It has surprisingly been found that the in the Drop separators located at the end of the flue gas ducts resulting rinse water and / or condensate for monitoring the flue gas desulphurization plants can be used nen.
Erfindungsgemäß wird daher vorgeschlagen, daß die gereinigten Gase über Tropfenabscheider geleitet werden, deren ablaufen de Spülwässer und/oder Kondensate auf ihre Leitfähigkeit untersucht werden. Auf diese Weise kann eine Verschlech terung der Tropfenabscheidung nach der Rauchgasentschwefe lungsanlage frühzeitig erkannt und eine Verschmutzung der nachgeschalteten Rauchgaskanäle und Komponenten vermindert werden.According to the invention it is therefore proposed that the cleaned Gases are passed through droplet separators, the drain of which de rinsing water and / or condensates for their conductivity to be examined. In this way, a deterioration Drop separation after flue gas desulphurization system recognized early and contamination of the downstream flue gas ducts and components reduced will.
Die zur vorteilhaften Ausgestaltung der Erfindung dienenden Merkmale sind Gegenstand der Unteransprüche.Those used for the advantageous embodiment of the invention Features are the subject of the subclaims.
Die Überwachung kann durch Vergleich der elektrischen Leit fähigkeit des Spülwassers vor und nach dem Kontakt mit den Tropfen erfolgen. Neben der elektrischen Leitfähigkeit sind Konzentrationsmessungen von Protonen, Chlorid-Alkali- oder Erdalkaliionen möglich.Monitoring can be done by comparing the electrical conductors Ability of the rinse water before and after contact with the Drops. In addition to electrical conductivity Concentration measurements of protons, chloride-alkali or Alkaline earth ions possible.
In Fällen, in denen die Spülwässer der Tropfenabscheider nicht zur Messung herangezogen werden, sei es, weil sie nicht zugänglich sind, sei es, weil keine vorhanden sind, können zusätzliche Abscheider in den Rauchgasweg einge setzt werden. Diese kleinen Abscheider dienen der Ge winnung von Meßdaten aus Tropfen und können mit einer Spülung ausgerüstet sein, so daß auch hier Differenz messungen möglich sind.In cases where the rinse water of the droplet separator not be used for the measurement, be it because of it are not accessible, either because there are none, additional separators can be inserted into the flue gas path be set. These small separators serve the Ge extraction of measurement data from drops and can be done with a Be flushed, so that here too difference measurements are possible.
