Description
Die Erfindung betrifft ein Verfahren zum Abdichten eines mit einem Deckel verschlossenen Fülloches an einem Koksofen, wobei der Ringspalt zwischen dem Deckel und einem Füllochrahmen mit einer Abdichtmasse vergossen wird, die nach dem Fließvorgang aushärtet.The invention relates to a method for sealing a filling hole closed with a lid on a coke oven, the annular gap between the lid and a Filling hole frame is potted with a sealing compound that hardens after the flow process.
In einem modernen Koksofenbetrieb werden die Spalträume an den nach der Kohlefüllung mit Deckeln verschlossenen Füllöchern mit einer Abdichtmasse vergossen, um Emissionen während des Verkokungsprozesses zu verhindern. Als Abdichtmasse werden wässrige Suspensionen verwendet, die nach dem Aushärten eine feste Abdichtung zwischen dem Deckel und dem Füllochrahmen bilden. Für das Ausbringen der Abdichtmasse werden Gießvorrichtungen eingesetzt, die auf dem Kohlefüllwagen installiert sind und von Hand oder automatisch betätigt werden können. Die Gießvorrichtungen weisen mit Absperrarmaturen versehene Zulaufleitungen zu den Übergabebereichen oberhalb der abzudichtenden Füllochdeckel auf.In a modern coke oven operation, the gaps are opened those closed with lids after the coal filling Pour fill holes with a sealant to reduce emissions to prevent during the coking process. As Sealants are used in aqueous suspensions after curing, a tight seal between the Form the lid and the fill hole frame. For spreading the Sealants are used on pouring devices the coal filling truck are installed and by hand or can be operated automatically. The pouring devices assign supply lines provided with shut-off valves the transfer areas above the area to be sealed Filling hole cover on.
In der Praxis kommt es immer wieder zu Betriebsstörungen durch Ablagerungen der Abdichtmasse an den Innenflächen des Leitungssystems sowie der Armaturen. Die bekannten Gießvorrichtungen bedürfen einer intensiven Wartung, um eine ordnungsgemäße Zuführung des Abdichtmaterials zu den zu verschließenden Ringspalten zu gewährleisten. Ablagerungen im Leitungssystem wirken sich auch auf den Durchsatz des Abdichtmaterials aus mit der Folge, daß eine betriebssichere und genaue Dosierung nicht möglich ist. Unterdosierungen und Überdosierungen kommen vor. Während im Fall einer Unterdosierung eine ausreichende Abdichtung nicht immer gewährleistet ist, ergibt sich bei einer Überdosierung das Problem, daß die Ringspalte zwischen Deckel und Füllochrahmen beim Gießvorgang überlaufen und das Abdichtmaterial auf die Füllochrahmen sowie die Ofendecke fließt und Verschmutzungen verursacht, die manuell entfernt werden müssen.In practice, there are always malfunctions by deposits of the sealing compound on the inner surfaces of the Pipe system and the fittings. The well-known pouring devices require intensive maintenance in order to proper supply of the sealing material to the to ensure closing annular gaps. Deposits in the piping system also affect the throughput of the Sealing material with the result that a reliable and exact dosing is not possible. Underdoses and overdoses occur. While in the case an underdosing does not provide adequate sealing is always guaranteed results from an overdose the problem that the annular gap between the lid and fill hole frame overflow during the casting process and that Sealing material on the filling frame and the furnace ceiling flows and causes pollution that is removed manually Need to become.
Der Erfindung liegt die Aufgabe zugrunde, das eingangs beschriebene Verfahren so weiter auszubilden, daß Reinigungs- und Wartungsarbeiten weitgehend entfallen.The invention has for its object that to further develop the described method so that cleaning and maintenance work are largely eliminated.
Zur Lösung dieser Aufgabe lehrt die Erfindung, daß aus einem auf einem Kohlefüllwagen mitgeführten Vorratsbehälter eine für den abzudichtenden Ringspalt vorher festgelegte Menge an Abdichtmasse entnommen und unter Druck einem ringförmigen Verteiler zugeführt wird, der oberhalb des Ringspaltes positioniert worden ist, und daß nach Maßgabe der vorgegebenen Abdichtmassenmenge das an den Vorratsbehälter austrittsseitig anschließende Leitungssystem bis zum Verteiler mit Wasser gespült wird. Vorzugsweise wird die Abdichtmasse tangential dem Verteiler zugeführt und tritt aus einem ringförmigen Spalt oder aus einer Mehrzahl von Bohrungen an der Unterseite des Verteilers mit einer gleichmäßigen Masseverteilung in Umfangsrichtung aus.To achieve this object, the invention teaches that a storage container carried on a coal filling truck one predefined for the annular gap to be sealed Amount of sealing compound removed and under pressure annular distributor is supplied, which is above the Annular gap has been positioned, and that in accordance with the specified amount of sealant to the reservoir downstream pipe system up to Distributor is rinsed with water. Preferably the Sealant is fed tangentially to the distributor and occurs from an annular gap or from a plurality of Holes on the bottom of the manifold with a uniform mass distribution in the circumferential direction.
Erfindungsgemäß wird nach jedem Gießvorgang eine Wasserspülung vorgenommen, um Ablagerungen zu verhindern. Ferner ist wesentlich, daß eine auf den Ringspalt abgestimmte und vorher festgelegte Menge dem Vorratsbehälter entnommen und unter Druck dem Verteiler zugeführt wird. Im Rahmen der Erfindung liegt es, für die Förderung Verdrängerpumpen einzusetzen, deren Förderstrom von der Förderhöhe weitgehend unabhängig ist. Die Dosiermenge ist über die Betriebszeit der Verdrängerpumpe steuerbar. Zur Förderung einer pastösen Abdichtmasse eignen sich beispielsweise Membran- und Faltenbalgpumpen sowie Schlauchdosierpumpen. Gemäß einer bevorzugten Ausführung der Erfindung, bei der eine Pumpe nicht erforderlich ist, wird ein als Druckbehälter ausgebildeter Dosierbehälter verwendet. Die Abdichtmasse fließt aus dem Vorratsbehälter in den Dosierbehälter ab. Nach Aufnahme der für die Abdichtung des Ringspaltes vorgegebenen Menge, die entweder durch die Größe des Dosierbehälters bestimmt ist oder durch eine Füllstandsmeßeinrichtung ermittelt wird, wird der Dosierbehälter oberseitig mit Druckluft beaufschlagt und die Abdichtmasse unter Ausbildung eines Druckluftpolsters dem Verteiler zugeführt. Nach Entleerung des Dosierbehälters wird dieser sowie die auslasseitig zum Verteiler führende Leitung mit Wasser gespült.According to the invention, a water rinse is carried out after each casting process made to prevent deposits. Further it is essential that a and previously determined amount removed from the storage container and is fed to the manifold under pressure. As part of the The invention is to use positive displacement pumps for conveying whose flow largely depends on the head is independent. The dosing quantity is over the operating time the displacement pump controllable. To promote a pasty Sealants are suitable for example membrane and Bellows pumps and peristaltic metering pumps. According to one preferred embodiment of the invention, in which a pump is not necessary, a trained as a pressure vessel Dosing container used. The sealing compound flows from the storage container into the dosing container. To Inclusion of the specified for sealing the annular gap Amount by either the size of the dispenser is determined or by a level measuring device is determined, the dosing container is on the top pressurized with compressed air and the sealing compound under Formation of a compressed air cushion supplied to the distributor. After emptying the dosing container, this and the line leading to the distributor with water rinsed.
Gemäß einer bevorzugten Ausführung der Erfindung wird mit einem Spülwasserkreislauf gearbeitet. Das zu Spülzwecken eingesetzte Wasser wird aus einem Spülwassertank entnommen, vor dem Verteiler aus dem Leitungssystem abgezogen und in den Spülwassertank zurückgeführt. Zumindest von Fall zu Fall sollte auch eine Spülung des ringförmigen Verteilers erfolgen. Die Wasserspülung des ringförmigen Verteilers wird zweckmäßig dann vorgenommen, wenn der Kohlefüllwagen in einem Kohlenturm mit Kohle befüllt wird. Das aus dem Verteiler austretende Spülwasser kann einer stationären Ablaufrinne im Kohlenturm zugeführt werden.According to a preferred embodiment of the invention worked in a rinsing water circuit. For rinsing purposes used water is taken from a rinse water tank, withdrawn from the pipe system in front of the distributor and into returned the rinse water tank. At least on a case by case basis Fall should also be a flushing of the annular manifold respectively. The water flushing of the ring-shaped distributor is expediently carried out when the coal filling truck is filled with coal in a coal tower. That from the Distributor flushing water can be a stationary Gutter can be fed into the coal tower.
