Description
Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.
Derartige Vorrichtungen sind aus dem DE-GM 91 08 270, dem DE-GM 89 09 189 und der DE-PS 39 20 321 bekannt.Such devices are known from DE-GM 91 08 270, DE-GM 89 09 189 and DE-PS 39 20 321.
Es hat sich gezeigt, daß sich bestimmte Stoffe, die ein niedrigeres spezifisches Gewicht als das Reinigungsmittel haben, auf dessen Oberfläche schwimmen. Stoffe, die gebunden sind, jedoch mit dem Reinigungsmittel nicht emulgieren können ebenfalls an die Oberfläche des Reinigungsmittels gelange, wenn dieses mittels einer Pumpe umgewälzt wird.It has been shown that certain substances that have a lower specific gravity than the cleaning agent float on its surface. Substances that are bound but cannot emulsify with the cleaning agent also reach the surface of the cleaning agent when it is circulated by a pump.
Der Erfindung liegt die Aufgabe zugrunde, die Vorrichtung der eingangs genannten Art hinsichtlich ihres Reinigunswirkungsgrades weiter zu verbessern. Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Anspruch 1 angegebenen Merkmale. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The invention is based on the object of further improving the device of the type mentioned at the beginning with regard to its cleaning efficiency. This object is achieved according to the invention by the features specified in claim 1. Appropriate embodiments of the invention emerge from the subclaims.
Die aus dem zu reinigenden Gas abgeschiedenen Stoffe, die sich nicht am Boden des Reinigungsbehälters sammeln, können durch die vorgeschlagene Ausbildung im Überlaufbehälter aufgefangen werden. Dabei sammelt sich am Boden dieses Behälters Reinigungsflüssigkeit, die dem Reinigungsbehälter wieder zugeführt werden kann.The substances separated from the gas to be cleaned that do not collect at the bottom of the cleaning tank can be collected in the overflow tank thanks to the proposed design. Cleaning fluid collects at the bottom of this tank and can be fed back into the cleaning tank.
Die Erfindung wird nachstehend anhand der beigefügten Zeichnung beispielsweise erläutert, die schematisch einen
Querschnitt der Vorrichtung zeigt.
35The invention is explained below by way of example with reference to the accompanying drawing, which schematically shows a cross-section of the device.

Zu reinigende Gase 1 werden in einen Reaktionsraum 5 der Vorrichtung geleitet. Im Reaktionsraum befinden sich drehbare, vorzugsweise leer laufende Walzen 3, die in eine Reinigungsflüssigkeit eintauchen, so daß eine Schaumbildung und eine intensive Kontaktierung mit den zu reinigenden Gasen erreicht wird. Die aus dem Reaktionsraum 5 nach oben austretende Schaummasse wird von einem Schaumzerleger 6 erfaßt und zu Flüssigkeit zerlegt. Diese fließt über eine Rücklaufleitung in einen Reinigungsmittelbehälter 8 zurück. Mittels einer Pumpe 4 wird dem Reinigungsbehälter 8 Reinigungsmittel entnommen und auf die Auffangbleche 14 gepumpt.Gases 1 to be cleaned are fed into a reaction chamber 5 of the device. In the reaction chamber there are rotating, preferably idle rollers 3 which are immersed in a cleaning liquid so that foam is formed and intensive contact with the gases to be cleaned is achieved. The foam mass emerging upwards from the reaction chamber 5 is captured by a foam breaker 6 and broken down into liquid. This flows back into a cleaning agent container 8 via a return line. Cleaning agent is removed from the cleaning container 8 by means of a pump 4 and pumped onto the collecting plates 14.
Auf der Oberfläche des Reinigungsmittels bildet sich ein Emulgat, das bestimmte, aus den Rauchgasen entfernte Stoffe enthält. Dieses Emulgat wird mittels eines Absaugstutzens 15 und eine durch ein Ventil 16 steuerbare ÜberlaufleitungAn emulsify containing certain substances removed from the flue gases forms on the surface of the cleaning agent. This emulsify is removed by means of a suction nozzle 15 and an overflow line controlled by a valve 16.
9 in einen Überlaufbehälter 10 abgeleitet. Im Überlaufbehälter 10 sammelt sich das Emulgat 11 über dem sich aus dem Emulgat absetzenden Reinigungsmittel, das über eine an den Behälterboden angeschlossene Rücklaufleitung 12 über die Pumpe 4 in den Reaktionsraum 5 zurückgeleitet wird. Es ist auch möglich, das Reinigungsmittel aus dem Überlaufbehälter9 into an overflow tank 10. In the overflow tank 10, the emulsify 11 collects above the cleaning agent that settles out of the emulsify, which is returned to the reaction chamber 5 via a return line 12 connected to the bottom of the tank via the pump 4. It is also possible to drain the cleaning agent from the overflow tank
10 erst abzuleiten, wenn der Überlaufbehälter nahezu mit Emulgat gefüllt ist. In diesem Falle erfolgt die Rückleitung unmittelbar in den Reinigungsbehälter 8, so daß noch vorhandenes Restemulgat in den Überlaufbehälter 10 abgeleitet werden kann.10 only when the overflow tank is almost full of emulsify. In this case, the return line is directly into the cleaning tank 8, so that any remaining emulsify can be drained into the overflow tank 10.
