Description

Verfahren zur Naßbehandlung von Verbrennungsrückständen aus Dampfkesselanlagen Die Erfindung betrifft ein Verfahren zur Naßbehandlung von Verbrennungsrückständen aus Dampfkesselanlagen.Process for the wet treatment of combustion residues from steam boiler systems The invention relates to a method for the wet treatment of combustion residues from steam boiler systems.

Der Erfindung liegt die Aufgabe zugrunde, eine beschleunigte Aufnahme der Schlacken- und Flugaschenteile in Wasser zu bewirken. Der bisherige Mangel besteht darin, daß die beispielsweise in einem Aschentrichter unter dem Rost oder einem Flugaschentrichter angesammelten Ascheteilchen, die in einen Wassersumpf abgerieselt werden, noch verhältnismäßig lange Zeit auf der Wasseroberfläche liegen, ohne abgelöscht zu werden. Dabei kommt es vor, daß die Aschenteile auf der Wasserschicht noch brennen und/oder eine Verdampfung des Wassers infolge der erst langsam eintretenden Ablöschung eintritt. Auch bei Naßentstaubungsanlagen, durch welche Ruß und Flugasche aus dem Rauchgasstrom ausgewaschen werden sollen, macht sich das langsame Eindringen der Staubteile in das Wasser nachteilig bemerkbar.The invention is based on the object of accelerated recording of the slag and fly ash particles in water. The previous deficiency exists in that, for example, in an ash funnel under the grate or a Fly ash funnel accumulated ash particles that trickled down into a water swamp remain on the surface of the water for a relatively long time without being extinguished to become. It happens that the ash particles are still burning on the water layer and / or an evaporation of the water as a result of the slowly occurring extinction entry. Even with wet dedusting systems, through which soot and fly ash from the Flue gas flow to be washed out, makes the slow penetration of the Dust particles in the water are noticeable disadvantageously.

Es ist nun an sich bekannt, daß man die Oberfläche von Flüssigkeiten durch Zugabe bestimmter Chemikalien zu einer schnellen Entspannung bringen kann. Dieses Entspannungsverfahren wird bisher vornehmlich für Reinigungszwecke angewendet, wobei auf diese Weise ein schnelles Eindringen der Schmutzteile, beispielsweise beim Spülen von Geschirr, in das Wasser erreicht wird. Die Erfindung besteht nun darin, daß man das zur Naßbehandlung der Verbrennungsrückstände verwendete Wasser mit die Oberflächenspannung des Wassers aufhebenden Chemikalien behandelt, indem man diese dem Wasser beigibt, so daß nunmehr die in das Wasser geleiteten Feuerungsrückstände und/oder Flugaschenteile unmittelbar nach ihrer Berührung mit der Wasseroberfläche von dieser spontan aufgenommen werden. Durch die Anwendung des Verfahrens z. B. bei der Entaschung von Feuerungen werden die Nachteile, die bisher bei Naßentaschungen bezüglich der durch das nur langsame Eindringen der leichteren staubigen Teilchen in das Wasserbad verursachten Unannehmlichkeiten völlig ausgeschaltet.It is now known per se that the surface of liquids can bring about rapid relaxation by adding certain chemicals. This relaxation process has so far mainly been used for cleaning purposes, in this way a rapid penetration of the dirt particles, for example when washing dishes in which water is reached. The invention now consists in using that for the wet treatment of the combustion residues Water treated with chemicals that cancels the surface tension of the water, by adding these to the water, so that now those that are conducted into the water Firing residues and / or parts of fly ash immediately after coming into contact with the water surface can be absorbed by this spontaneously. Through the application of the process z. B. in ash removal from furnaces are the disadvantages that so far with wet ash removal with regard to the slow penetration of the lighter ones Dusty particles in the water bath caused inconvenience completely eliminated.

Gemäß der Erfindung sind zur Behandlung des Wasserbades die Salze der Celluloseglykolsäure, z. B. das Na-Salz derselben, in besonderer Weise geeignet, deren Zugabe kontinuierlich mit einstellbarer Dosierung erfolgen kann.According to the invention, the salts are used for treating the water bath cellulose glycolic acid, e.g. B. the sodium salt of the same, particularly suitable, which can be added continuously with adjustable dosing.
