Description
Die Erfindung betrifft eine Einrichtung zur Eindüsung eines Strömungsmediums, insbesondere des Kühlmediums Wasser, in einen Heißgasstrom, der mit zu Anbackungen neigenden Staubfrachten und/oder kondensierenden/kristallisierenden Dämpfen belastet ist, insbesondere in der Mischkammer einer Bypass- bzw. Teilgasabzugs-Anlage zum Abzug eines schadstoffhaltigen Teilstromes des Drehofenabgases einer Zementklinkerproduktionslinie mit Kühlung des zu entstaubenden Teilgasstromes.The The invention relates to a device for injecting a flow medium, in particular the cooling medium Water, in a hot gas stream, the with caking tendency to dust and / or condensing / crystallizing dampen is loaded, in particular in the mixing chamber of a bypass or Partial gas withdrawal system for the withdrawal of a pollutant-containing partial flow of the rotary kiln exhaust gas a cement clinker production line with cooling of the dedusting Partial gas stream.
In der Technologie der Herstellung von Zementklinker aus Zementrohmehl, das in wenigstens einem vom Abgas eines Drehrohrofens durchströmten Wärmetauscherstrang insbesondere Zyklonschwebegaswärmetauschersystem vorerhitzt und in der Sinterzone des Drehrohrofens zu Zementklinker gebrannt wird, ist es bekannt, daß viele Einsatzstoffe, ggfs. auch die Brennstoffe, Nebenbestandteile wie z. B. Alkaliverbindungen, Chlor, Schwefelverbindungen, Schwermetalle etc. enthalten, die im Bereich der Sinterzone z. B. als Alkalichlorid- und Alkalisulfatverbindungen verdampfen, im Vorwärmerbereich wieder kondensieren/kristallisieren und somit Kreisläufe aufbauen, wodurch sowohl die Qualität des Zementklinkers ungünstig beeinflußt als auch der Brennprozeß selbst erheblich gestört werden können. Zur Unterdrückung solcher Kreisläufe in einer Zementklinkerbrennanlage sowie zur Reduzierung des Gehaltes kreislaufbildender Stoffe im Klinkerherstellungsprozeß ist es bekannt (z. B. DE-A- 197 18 259), durch einen sogenannten Bypassgasabzug bzw. Teilgasabzug einen Teil der die Alkaliverbindungen enthaltenden heißen staubbeladenen Ofenabgase aus dem unteren Bereich der Drehofenabgassteigleitung bzw. direkt aus der Drehofeneinlaufkammer abzuzweigen, in einer Mischkammer durch Einführung eines Kühlmediums wie Wasser und/oder Außenluft abzukühlen, die im Teilgasstrom enthaltenen dampfförmigen Schadstoffe an den Feststoffpartikeln kondensieren zu lassen und dann den abgekühlten Teilgasstrom durch Abtrennung des schadstoffhaltigen Staubes zu reinigen.In the technology of producing cement clinker from cement raw meal, in at least one of the exhaust gas of a rotary kiln through which flowed heat exchanger strand in particular, cyclone float gas heat exchanger system preheated and fired in the sintering zone of the rotary kiln to cement clinker it is known that many Starting materials, if necessary. Also the fuels, secondary components such as z. As alkali compounds, chlorine, sulfur compounds, heavy metals etc., which in the sintering zone z. B. as alkali chloride and alkali sulfate compounds evaporate, condense again in the preheater area / crystallize and thus cycles build, whereby both the quality of the cement clinker adversely affected as well the burning process itself considerably disturbed can be. For suppression such circuits in a cement clinker burning plant as well as to reduce the content of the circulation Fabrics in the clinker production process it is known (eg DE-A-197 18 259), by a so-called Bypassgasabzug or Teilgasabzug a part of the alkali compounds containing hot dust-laden kiln exhaust gases from the lower area of the rotary kiln exhaust gas riser or directly to branch off from the rotary kiln inlet chamber, in a mixing chamber through introduction a cooling medium like water and / or outside air cool, the vaporous pollutants contained in the partial gas flow on the solid particles to condense and then the cooled partial gas stream by separation to clean the pollutant-containing dust.
Um die zu behandelnden Volumina des Teilgasstromes nicht zu groß werden zu lassen, ist es vorteilhaft, in den z. B. 1100°C heißen Teilgasstrom statt Außenluft Wasser einzudösen, das eine Schockkühlung des Teilgasstromes bewirken soll. Gerade besonders bei der Eindüsung von Kühlwasser ist aber die Gefahr nicht ausgeschlossen, daß es im Bereich der Einspritzdüse zu Feststoffanbackungen kommt, weil der abzukühlende heiße Teilgasstrom die als Kondensationskeime dienenden Staubfrachten sowie die kondensierenden/kristallisierenden Schadstoffdämpfe mit sich führt, die bei ihrer raschen Abkühlung zu Anbackungen neigen, welche die Kühlmittel-Eindüsung funktionsunfähig machen können.Around the volumes of the partial gas stream to be treated do not become too large to let, it is advantageous in the z. B. 1100 ° C hot gas flow instead of outside air To dilute the water, that a shock cooling to cause the partial gas flow. Especially with the injection of cooling water but the risk is not excluded that it is in the injection nozzle to Feststoffanungen comes because the one to be cooled name is Partial gas stream serving as condensation nuclei dust loads and the condensing / crystallizing pollutant vapors with leads, in their rapid cooling tend to caking, which is the coolant injection inoperable can do.
Der Erfindung liegt daher die Aufgabe zugrunde, eine einfach gebaute Einrichtung zur Eindüsung eines Strömungsmediums, insbesondere des Kühlmediums Wasser in einen Heißgasstrom zu schaffen, der wie bei einer Bypassgas- bzw. Teilgasabzugsanlage einer Zementklinkerproduktionslinie mit zu Anbackungen neigenden Staubfrachten und/oder kondensierenden/kristallisierenden Dämpfen belastet ist, wobei die Düse über eine lange Standzeit funktionsfähig bleiben soll.Of the Invention is therefore based on the object, a simply built Device for injection a flow medium, in particular the cooling medium Water in a hot gas stream to create, as in a bypass gas or partial gas exhaust a cement clinker production line with caking tendency Dust loads and / or condensing / crystallizing vapors loaded is, with the nozzle over a long service life should stay.

Das Abreinigungsmedium kann ein Druckgas und/oder eine Druckflüssigkeit sein. Das Kühlmedium, z. B. Kühlwasser, sowie das Abreinigungsmedium können sogar identisch sein. Eine einfache und doch wirkungsvolle Abreinigung der Kühlmitteldüse gelingt z. B. dann, wenn von der Abreinigungsdüse intermittierend Druckluftstöße abgegeben werden, wobei die Impulslänge und/oder die Impulsfrequenz der Druckluftstöße in Abhängigkeit der Meßgröße des Verkrustungszustandes der jeweiligen Kühlmediumdüse steuerbar sein können. Jedenfalls wird durch die Erfindung eine vollkommen selbsttätige Abreinigung der jeweiligen Kühlmitteleinspritzdüse erreicht.Characteristic for the Self-cleaning according to the invention injection especially cooling water injection, that against the cooling medium nozzle at least another nozzle for ejection a cleaning medium directed to the automatic cleaning of the cooling medium is. The cleaning medium can be a compressed gas and / or a pressure fluid be. The cooling medium, z. As cooling water, as well as the cleaning medium can even be identical.
