Abstract

The gravimetric separator comprises an immersion pipe of varying dia. and rectifier surfaces which are mounted in an external zone between the wall of the immersion pipe and the outer wall of the separator. Contaminated liq. e.g. water used for gas scrubbing, is supplied to the separator via the immersion pipe. Where the width of the pipe is increased, the rate of flow of water is reduced, and sepn. of solid particles is improved in the sump of the separator. At the transition zone from the wide part of the pipe is an increase in surface area, converting fine particles to a state of suspension and agglomerating them so that they fall back down into the sump.

Description

Beschreibung und Erläuterung zur Patentanmeldung "Doppelmantel-Sinkabscheider" Bei Umweltschutzanlagen, die nach dem Naßverfahren Gasreinigungen bewirken, muß das Wasser bzw. die Waschflüssigkeit von Feststoffen befreit werden.Description and explanation of the patent application "double jacket sink separator" For environmental protection systems that effect gas cleaning according to the wet process, must solids are removed from the water or the washing liquid.

Hierzu benutzt man vielfach Doppelmantel-Sinkabscheider.Double jacket sink separators are often used for this purpose.

Bei den Doppelmantel-Sinkabscheidern handelt es sich um große Gefäße, die mit einem inneren Mantel in Tauchrohrform ausgebildet sind, und das Wasser wird innen in das Tauchrohr oder außen in den äußeren Rand zugegeben, und über das Sinkvermögen der einzelnen Feststoffteilchen werden die Teilchen nach unten absinken und das Sauberwasser an die Oberfläche bringen.The double jacket sink separators are large vessels, which are formed with an inner jacket in the shape of a dip tube, and the water is added inside the dip tube or outside in the outer edge, and about the sinking capacity of the individual solid particles, the particles will sink down and that Bring clean water to the surface.

Um diesen Effekt wesentlich zu verbessern, wird erfindungsgemäß vorgeschlagen: Die schmutzige Flüssigkeit wird bei (1) über das Tauchrohr dem Doppelmantel-Sinkabscheider zugeführt. Bei (2) ist das Tauchrohr wesentlich erweitert, die Geschwindigkeit des abfließenden Wassers läßt nach, und ein Abtrennen der Feststoffteilchen bei (3) im Sumpf des Doppelmantel-Sinkabscheiders wird verbessert.In order to significantly improve this effect, it is proposed according to the invention: The dirty liquid is at (1) via the immersion pipe to the double jacket sink separator fed. At (2) the immersion tube is significantly expanded, the speed of the draining water decreases, and a separation of the solid particles at (3) in the sump of the double jacket sink separator is improved.

Weiterhin ist erfindungsgemäß an der Übergangszone von dem Bereich (2) außerhalb des Bereichers (1) des Tauchrohres eine Vergrößerung (4) der Fläche im Außenkranz vorgesehen.Furthermore, according to the invention is at the transition zone from the area (2) outside the area (1) of the immersion tube, an enlargement (4) of the area provided in the outer rim.

Durch diese erfindungsgemäßen, plötzlichen Vergrößerungen 2 + 4 werden die Feinstteilchen, die im Auftrieb befaßt sind, in einen Schwebezustand versetzt und agglomerieren insbesondere, wenn Flockungsmittel zugesetzt werden.These sudden enlargements according to the invention become 2 + 4 the fine particles, which are involved in buoyancy, are placed in a state of suspension and particularly agglomerate when flocculants are added.

Durch die Agglomeration werden die Teilchen schwerer und sinken nach unten in den Sumpf (3) ab. Um in der sogenannten Verzögerungs- und Agglomerationszone eine gleichmäßige Beaufschlagung zu erzielen, wird erfindungsgemäß vorgeschlagen, in den Bereich (4) vorzugsweise Gleichrichterflächen (5) einzusetzen.The agglomeration makes the particles heavier and sinks down into the sump (3). To in the so-called delay and agglomeration zone to achieve a uniform application is proposed according to the invention, Preferably use rectifier surfaces (5) in the area (4).

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen und dargestellten Ausbildungsformen beschränkt, sondern es sind zahlipiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Schwerkraftabscheider als Doppelmantel-Sinkabscheider auszubilden, wobei dieser Doppelmantel-Sinkabscheider so ausgebildet ist, daß durch die Form des Tauchrohres Zone 1 schlanker als Zone 2eine Verzögerungszone im Außenmantel (4), Bereich Übergang Zone 2 nach 1, entsteht und hierdurch eine größere Schmutzkörnchen-oder Flockenbildung geschaffen wird, die ein Absinken in den Sumpf 3 bewirkt.Of course, the invention is not limited to the above in detail The forms of training described and illustrated are limited, but there are numerous Modifications possible, but without deviating from the basic idea, a gravity separator to be designed as a double jacket sink separator, this double jacket sink separator is designed so that by the shape of the dip tube Zone 1 slimmer as zone 2, a delay zone in the outer jacket (4), area of transition zone 2 to 1, arises and thereby creates a larger amount of dirt grains or flakes which causes a sinking into the sump 3.
