Abstract

An assembly removes oil and grease from an oil-water emulsion. The assembly has a holding tank (7), a reactor container (2) and a filter chamber (6). The free non-emulsified oil (9) is separated in and removed from the holding tank (7). Pre-cleaned water from the holding tank (7) is transferred by pump and pipe to the reaction vessel (2) where it is agitated by a mixer (4) an intermixed with a dosed powder separation agent (3) creating flock. The flock is discharged from the reactor vessel (2) alternating to two filter bags within a single filter chamber (6).

Description

Die Erfindung betrifft eine Vorrichtung zum Abtrennen und Entfernen von Ölen und tierischen sowie pflanzlichen Fetten aus einer Öl-Wasser-Emulsion. Diese Öl-Wasser-Emulsionen fallen bei Produktions- und Dienstleistungsprozessen, insbesondere als Druckluftkondensate an.The The invention relates to a device for separating and removing of oils and animal and vegetable fats from an oil-water emulsion. These oil-water emulsions fall in production and service processes, in particular as Compressed air condensates on.

So wurde ein Verfahren zur Behandlung und Reinigung von ölhaltigen Abwässern bekannt, bei dem das Abwasser zu erst durch ein Sandfilter und anschließend durch eine biologische Tropfkörperanlage geleitet wird ( DE 2461727 ).Thus, a process for the treatment and purification of oily effluents has been known in which the wastewater is first passed through a sand filter and then through a biological trickle filter system ( DE 2461727 ).

Weiterhin wurde ein Verfahren und eine Vorrichtung zum Reinigen von ölhaltigen Abwässern bekannt, bei dem das ölhaltige Abwasser durch wenigstens einen mit ferromagnetischen Teilchen gefüllten Leitungsabschnitt hindurch geleitet wird, wobei die kornhaltigen Teilchen magnetisch in ihrer Lage zusammengehalten werden (OS-PS 328980).Farther has been a method and apparatus for purifying oily ones wastewater known in which the oil-containing Wastewater through at least one ferromagnetic particle filled line section passed through, wherein the grain-containing particles magnetic be held together in their position (OS PS 328980).

Ebenso wurde eine Anlage zum Abtrennen und Entfernen von ölhaltigen Substanzen aus Flüssigkeiten mit vertikalen, teilweise in die Flüssigkeit eintauchenden Scheiben, Schabklingen zum Ablösen der an den Scheiben anhaftenden ölhaltigen Substanzen in einen Behälter zur Sammlung der abgetrennten Substanzen bekannt, wobei der Behälter ein unter der Abgabezone der Schabklingen angeordneter trichterförmiger Sammler ist, aus dem eine Falleitung mit einem pneumatisch gesteuerten Ventil angeordnet ist, die in einen Autoklaven mündet, der mit Einrichtungen zur periodischen und/oder nach Wägung erfolgenden pneumatischen Abführung der abgetrennten Substanzen versehen ist ( DE 2757041 ).Also, a plant for separating and removing oily substances from liquids having vertical slices partially immersed in the liquid, scraper blades for detaching the oily substances adhering to the slices to a collection substance collection vessel has been known, the vessel being located below the discharge zone the scraper blade is arranged funnel-shaped collector, from which a downpipe is arranged with a pneumatically controlled valve, which opens into an autoclave, which is provided with means for periodic and / or after weighing pneumatic discharge of the separated substances ( DE 2757041 ).

Letztlich wurde eine Vorrichtung zum Trennen eines Öl-Wassergemisches bekannt, bestehend aus einem Trennbecken und zwei unterschiedlich hohe, durch eine Wand getrennte Überläufe aufweist, wobei der höhere Überlauf das abgeschiedene Öl zu einem geschlossenen, unter dem Innendruck des Abscheidegerätes stehenden Sammelbehälter führt, der tiefere Überlauf zu einer Pumpe führt, die das für den Betrieb der Vorrichtung erforderliche Vakuum bildet und das getrennte Wasser wegpumpt ( DE 2910307 ).Finally, a device for separating an oil-water mixture has been known, consisting of a separating basin and two different levels, separated by a wall overflows, the higher overflow leads the separated oil to a closed, standing under the internal pressure of the separator collecting tank, the deeper Overflow leads to a pump, which forms the necessary for the operation of the device vacuum and the separate water pumped away ( DE 2910307 ).

Alle bekannten Lösungen haben den Nachteil, dass mit ihnen wasseremulgiertes, feinverteiltes Öl nicht abgetrennt werden kann.All known solutions have the disadvantage that they do not emulsify with water, finely divided oil can be separated.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung zum Abtrennen und Entfernen von Öl-Wasser-Emulsion vorzuschlagen, bei der nicht nur aufschwimmendes Öl sondern emmulgierte Ölanteile abgetrennt und entfernt werden können.It is therefore an object of the invention, a device for separating and removing oil-water emulsion to propose, not only floating oil but Emmulgierte oil fractions separated and can be removed.

Erfindungsgemäß wird die Aufgabe durch eine sensorisch geregelte und elektronisch gesteuerte Vorrichtung zum Abscheiden von in wasseremulgierten Ölen bestehend aus einem Vorlagetank, einem Reaktionsbehälter und einer Filterkammer gelöst. Die Emulsion wird zunächst in den Vorlagetank eingeleitet, in dem sich nicht emulgierte Ölanteile auf der Oberfläche absetzen und entfernt werden. Anschließend wird die Emulsion in den mit einem Rührwerk ausgestatteten Reaktionsbehälter gefördert und mittels eines Spaltmittelförderers Spaltmittel in definierter Menge zugegeben. Das an sich pulverförmige Spaltmittel quillt in der Emulsion zu Flocken auf und die emulgierten Ölanteile werden von diesen Flocken vollständig aufgenommen. Anschließend werden die Flocken in die Filterkammer in einen von zwei Filtersäcken gefördert, wobei das gereinigte Wasser nach außen tritt und abgepumpt werden kann. Der im Filtersack befindliche Filterkuchen wird verworfen.According to the invention Task by a sensory and electronically controlled Device for separating in water-emulsified oils from a storage tank, a reaction tank and a filter chamber solved. The emulsion is first introduced into the storage tank, in which non-emulsified oil fractions on the surface settle and be removed. Subsequently, the emulsion in the with a stirrer equipped reaction vessel promoted and by means of a splitting agent conveyor Splitting agent added in a defined amount. The per se pulverulent splitting agent swells in the emulsion into flakes and the emulsified oil components become complete of these flakes added. Subsequently The flakes are conveyed into the filter chamber in one of two filter bags, wherein the purified water to the outside occurs and can be pumped out. The filter cake in the filter bag is discarded.

Das elektronisch gesteuerte, wechselseitige, diskontinuierliche Beschicken der beiden Filtersäcke gestattet ein effektives und damit kostengünstigeres Betreiben der Anlage. Das diskontinuierlich betriebene Befüllen des Reaktionsbehälters mit voreinstellbaren Reaktionsvolumina verbunden mit der sensorisch geführten präzisen Spaltmitteldosierung gewährleistet eine vollständige Beseitigung des emulgierten Ölanteils bei einem minimalen Spaltmittelverbrauch.The electronically controlled, reciprocal, discontinuous charging allowed the two filter bags an effective and thus more cost-effective operation the plant. The discontinuously operated filling of the reaction vessel with Pre-settable reaction volumes combined with the sensor-guided precise splitting agent dosing guaranteed a complete Elimination of the emulsified oil content with a minimum consumption of splitting agent.

Die Filtersäcke können mittels Schnellverschlüssen im laufenden Betrieb leicht ausgewechselt werden.The filter bags can by means of quick-release fasteners be easily replaced during operation.
