Description

Gegenstand der Erfindung ist ein Separator zum Trennen nichtmischbarer Flüssigkeiten, die Feststoff enthalten, der spezifisch schwerer ist als die schwerere der Flüssigkeiten, mit konischer Trommel, in der Trennhilfen angeordnet sind und in die Zulaufrohr, Greifer und Ablaufrohr hineinragen.The invention relates to a separator for separating immiscible liquids which contain solids, which is specifically heavier than the heavier liquids, with a conical drum in which separation aids are arranged and project into the inlet pipe, gripper and outlet pipe.

Flüssigkeiten aus chemischen Prozessen enthalten in der Regel feste Verunreinigungen, wie z.B. Rostteilchen, nichtlösliche Salzanteile und ähnliches. Ihre Konzentration liegt in der Größenordnung von Bruchteilen von Promille bis Prozent. Diese Feststoffanteile sind sehr oft für den weiteren Produktionsgang aufgrund ihrer geringen Konzentration völlig irrelevant und können dann für gewöhnlich im Prozess verbleiben, ohne beim weiteren Prozessablauf im geringsten zu stören. Bei der in einem Separator durchgeführten Trennung der Flüssigkeiten werden sie jedoch zwangsläufig mit abgetrennt, wenn sie spezifisch schwerer sind als die schwerere der beiden Flüssigkeiten. Je nach Menge des Feststoffanteils wird dann die Separatortrommel mehr oder weniger schnell von diesen Feststoffanteilen gefüllt, so daß eine Trennung der Flüssigkeiten nicht mehr möglich ist. Die Folge ist, daß die Separatoren häufig gesäubert werden müssen. Dieses Säubern erfordert einen hohen manuellen Arbeitsaufwand und führt zu einer beträchtlichen Kapazitätsverminderung des jeweiligen Separators.Liquids from chemical processes usually contain solid impurities, e.g. Rust particles, insoluble salt and the like. Their concentration is on the order of fractions of a thousand to percent. These solids fractions are very often completely irrelevant for the further production process due to their low concentration and can then usually remain in the process without interfering in the slightest with the further process flow. When the liquids are separated in a separator, however, they are also necessarily separated if they are specifically heavier than the heavier of the two liquids. Depending on the amount of solids, the separator drum is filled with these solids more or less quickly, so that it is no longer possible to separate the liquids. The result is that the separators often have to be cleaned. This cleaning requires a lot of manual work and leads to a considerable reduction in the capacity of the respective separator.

Es sind selbstreinigende Separatoren bekannt, deren Trommel Schlitze oder Düsen aufweisen, die manuell oder automatisch geöffnet werden, sobald sich der Schlammraum gefüllt hat.Self-cleaning separators are known whose drums have slots or nozzles that are opened manually or automatically as soon as the sludge space has filled up.

Bei Vorhandensein vieler Feststoffe versagen diese Separatoren, da die Feststoffteilchen während des Separationsvor- ganges derart fest miteinander verbacken, daß sie beim Öffnen der Reinigungsschlitze nicht ausgeschleust werden. Der Einsatz von Düsen für dieses Problem brachte deshalb keinen Erfolg, weil die Steuerung des Trennprozesses mit Hilfe der Düsen versagte.If many solids are present, these separators fail because the solid particles bake together so firmly during the separation process that they are not removed when the cleaning slots are opened. The use of nozzles for this problem was unsuccessful because the control of the separation process using the nozzles failed.

Ein weiterer Nachteil ist darin zu sehen, daß die bekannten Separatoren versagen, wenn der Schmelzpunkt einer oder beider Komponenten ein gewisses Maß über Raumtemperatur liegt. Während man diese Komponenten bei anderen physikalischen oder physikalisch-chemischen Prozeßstufen durch Aufschmelzen sehr vorteilhaft in der flüssigen Phase handhaben kann, ist eine Möglichkeit der Trennung der Komponenten in der flüssigen Phase mit Hilfe von Separatoren nicht gegeben, da die bekannten Separatoren aufgrund ihrer Konstruktion im Prinzip nicht heizbar sind.Another disadvantage is that the known separators fail when the melting point of one or both components is a certain amount above room temperature. While these components can be handled very advantageously in the liquid phase at other physical or physico-chemical process stages by melting, there is no possibility of separating the components in the liquid phase with the aid of separators, since the known separators are in principle due to their construction are not heatable.

Die Aufgabe zu vorliegender Erfindung besteht demnach darin, einen Separator zu schaffen, mit dem zwei nicht miteinander mischbare Flüssigkeiten, die Feststoff enthalten, der spezifisch schwerer ist als die schwerere der beiden Flüssigkeiten, quantitativ getrennt werden können. Gleichzeitig soll die Möglichkeit bestehen, den Trennraum zu heizen bzw. zu kühlen.The object of the present invention is therefore to provide a separator with which two immiscible liquids containing solid which is specifically heavier than the heavier of the two liquids can be separated quantitatively. At the same time, there should be the possibility of heating or cooling the separation space.

Die Aufgabe wird durch einen Separator gelöst, der dadurch gekennzeichnet ist, daß die Trommel innerhalb einer statischen Druckkammer angeordnet ist und am Äquator Öffnungen aufweist, die in die statische Druckkammer münden, und die statische Druckkammer mit einer verstellbaren Entnahmecinrichtung versehen ist.The object is achieved by a separator, which is characterized in that the drum is arranged within a static pressure chamber and has openings on the equator which open into the static pressure chamber, and the static pressure chamber is provided with an adjustable removal device.

In einer Ausgestaltung ist die Trommel in mehrere doppelt konische Räume aufgeteilt, an deren Spitze die Öffnungen angeordnet sind, durch die die schwere den Feststoff enthaltende Phase in die statische Druckkammer austritt. Um zu vermeiden, daß der Feststoff vor den Öffnungen sedimentiert, wird die Steigung der Wände der konischen Trommel bzw. der doppelt konischen Räume zweckmässig größer oder gleich dem Böschungswinkel des abzutrennenden Feststoffes gewählt. Um die in der statischen Druckkammer befindliche schwere Phase in etwa phasengleicher Rotation mit dem Inhalt der Trommel zu halten, können auf der Außenseite der Trommelwand Einrichtungen zum Mitnehmen der schweren Phase, wie z.B. Rippen und dergleichen angeordnet sein. Zur Vermeidung von Reibung kann die statische Druckkammer im Inneren oberflächenvergütet sein, z.B.'hochglanzpoliert. Für den gemeinsamen Austrag von schwerer Phase und Feststoff ist die statische Druckkammer mit einem Greifer oder einem Endwehr als Entnahmeeinrichtung versehen. Wehr oder Greifer sind dabei so angeordnet und bezüglich ihrer Durchmesser so bemessen, daß die Trennzone der beiden Phasen an günstiger Stelle innerhalb der rotierenden Trommel liegt. Ist die statische Druckkammer konisch ausgebildet, können Öffnungen am Äquator der konischen Druckkammer als Entnahmeeinrichtung dienen. Die Öffnungen können mit Ventilen versehen sein, die, falls gewünscht, von einer Meßsonde gesteuert werden, die in der Druckkammer in Sollhöhe des Gemisches aus schwerer Phase und Feststoff angeordnet ist. Zwecks indirektem Kühlen bzw. Heizen des Separatorinhaltes kann die statische Druckkammer doppelwandig ausgebildet sein. Bei Verwendung einer konisch ausgebildeten statischen Druckkammer sollte die Steigung der Wände wiederum größer oder gleich dem Böschungswinkel des abzutrennenden Feststoffes gewählt werden.In one embodiment, the drum is divided into several double-conical spaces, at the top of which the openings are arranged through which the heavy phase containing the solid exits into the static pressure chamber. In order to prevent the solid from sedimenting in front of the openings, the slope of the walls of the conical drum or of the double-conical spaces is expediently chosen to be greater than or equal to the angle of repose of the solid to be separated off. In order to keep the heavy phase in the static pressure chamber in approximately in-phase rotation with the contents of the drum, devices for taking the heavy phase, such as ribs and the like, can be arranged on the outside of the drum wall. To avoid friction, the static pressure chamber can be surface-coated on the inside, for example, ' highly polished. The static pressure chamber is equipped with a gripper or a weir as a removal device for the joint discharge of heavy phase and solid matter. Weir or gripper are arranged and dimensioned with respect to their diameter so that the separation zone of the two phases lies at a convenient location within the rotating drum. If the static pressure chamber is conical, openings on the equator of the conical pressure chamber can serve as a removal device. The openings can be provided with valves which, if desired, are controlled by a measuring probe which is arranged in the pressure chamber at the desired height of the mixture of heavy phase and solid. The static pressure chamber can be double-walled for the purpose of indirect cooling or heating of the separator contents. When using a conical static pressure chamber, the slope of the walls should again be chosen to be greater than or equal to the angle of repose of the solid to be separated.

In die rotierende konische Trommel 7 des Separators, die mit Trennhilfen, dem Leitteller 5 für das eintretende Gemisch und den Trenntellern 6 versehen ist, ragt das Zulaufrohr 1 für das Gemisch hinein. Konzentrisch zum Zulaufrohr 1 ist das Ablaufrohr 2 für die leichte Phase angeordnet und mit demselben verbunden. Zulaufrohr 1 und Ablaufrohr 2 sind wiederum mit der statischen Druckkammer 11 verbunden. In der Trommel 7 wird die leichte Phase mit einem Greifer 4 abgenommen. Der Greifer 4 ist an dem in die Trommel hineinragenden Ende des Ablaufrohrs 2 angeordnet. Der Leitteller 5, über den das zu trennende Gemisch in die Trommel verteilt wird, ist über Stege 14 mit der Trommel 7 verbunden. Die Trennteller 6, Kegelstümpfe, sind konzentrisch um den Leitteller 5 auf demselben aufgeschichtet. Der Durchmesser des Greifers 4 muß kleiner sein als der kleinste Durchmesser der Trennteller 6. Leitteller 5 und Trennteller 6 sind mit Ausnehmungen 15 versehen. Auf der Ebene dieser Ausnehmungen soll in etwa die Trennzone liegen, in der das Gemisch in leichte Flüssigkeit (Phase) und schwere Flüssigkeit (Phase), die gegebenenfalls noch Fest- stoff enthält, getrennt werden. Die Trommel 7 ist mit einer Antriebswelle 12 verbunden. Um Toträume für den Feststoff zu vermeiden, kann die Trommel 7 doppelt konisch ausgebildet sein. Die Steigungen α und γ der Trommelwände sind größer oder gleich dem Böschungswinkel des Feststoffs zu wählen. Unter Böschungswinkel soll das Verhältnis von Böschungshöhe zu Böschungsbreite verstanden werden. An ihrem Äquator ist die Trommel 7 mit Öffnungen 13 versehen, die in die statische Druckkammer 11 münden. Auf der Oberfläche der Trommel 7 können Einrichtungen, z.B. Rippen 8, zum Mitnehmen der schweren Phase angeordnet sein.The inlet pipe 1 for the mixture projects into the rotating conical drum 7 of the separator, which is provided with separation aids, the guide plate 5 for the incoming mixture and the separation plates 6. The outlet pipe 2 for the light phase is arranged concentrically with the inlet pipe 1 and connected to the same. Inlet pipe 1 and outlet pipe 2 are in turn connected to the static pressure chamber 11. In the drum 7, the light phase is removed with a gripper 4. The gripper 4 is arranged on the end of the drain pipe 2 projecting into the drum. The guide plate 5, via which the mixture to be separated is distributed into the drum, is connected to the drum 7 via webs 14. The separating plate 6, truncated cones, are stacked concentrically around the guide plate 5 on the same. The diameter of the gripper 4 must be smaller than the smallest diameter of the separation plate 6. The guide plate 5 and the separation plate 6 are provided with recesses 15. At the level of these recesses there should be approximately the separation zone in which the mixture is separated into light liquid (phase) and heavy liquid (phase), which may also contain solids. The drum 7 is connected to a drive shaft 12. In order to avoid dead spaces for the solid, the drum 7 can be double conical be trained. The slopes α and γ of the drum walls should be chosen to be greater than or equal to the slope angle of the solid. Under slope angle the ratio of B öschungshöhe shall be understood to embankment width. At its equator, the drum 7 is provided with openings 13 which open into the static pressure chamber 11. Devices, for example ribs 8, can be arranged on the surface of the drum 7 to take the heavy phase with them.

Ebenso wie die Trommel 7 kann auch die Druckkammer 11 konisch gestaltet sein. Sie ist mit einer Entnahmeeinrichtung für die schwere Phase versehen. Die Entnahmeeinrichtung kann ein Wehr 3, ein Greifer 9 sein oder, falls die statische Druckkammer 11 konisch ausgebildet ist, aus mehreren Öffnungen 10 bestehen, die am Äquator der konischen statischen Druckkammer 11 angeordnet sind. Die Öffnungen 10 können mit Ventilen 16 versehen sein. Zur automatischen Steuerung sind die Ventile 16 mit einer Standanzeige 17, z.B. einer Meßsonde, verbunden. Der Durchmesser des Wehres 3 bzw. des Greifers 9 muß größer sein als der Durchmesser des Greifers 4. Vom Durchmesser des Wehres 3 bzw. des Greifers 9 hängt auch die Lage der Trennzone in der Tromel ab. Auch bei der konischen statischen Druckkammer 11 ist die Steigung ß der Wände größer oder gleich dem Böschungswinkel des Feststoffes zu wählen. Bei Verwendung eines Wehres 3 sammelt sich die schwere Phase in einem Fangraum 19 und läuft dann über Rohr 18 ab. Bei Verwendung eines Greifers läuft die schwere Phase über Ablauf 20 ab, der konzentrisch zum Zulaufrohr 1 angeordnet ist. Zum indirekten Zuführen bzw. Abführen von Wärme kann die statische Druckkammer 11 mit einem Doppelmantel 21 versehen sein.Like the drum 7, the pressure chamber 11 can also be conical. It is equipped with a removal device for the heavy phase. The removal device can be a weir 3, a gripper 9 or, if the static pressure chamber 11 is conical, consist of several openings 10 which are arranged on the equator of the conical static pressure chamber 11. The openings 10 can be provided with valves 16. For automatic control, the valves 16 are equipped with a level indicator 17, e.g. a measuring probe. The diameter of the weir 3 or the gripper 9 must be larger than the diameter of the gripper 4. The position of the separation zone in the drum also depends on the diameter of the weir 3 or the gripper 9. In the case of the conical static pressure chamber 11, the slope β of the walls is to be chosen to be greater than or equal to the slope angle of the solid. When using a weir 3, the heavy phase collects in a trap chamber 19 and then runs off via pipe 18. When using a gripper, the heavy phase runs through outlet 20, which is arranged concentrically with the inlet pipe 1. For the indirect supply or removal of heat, the static pressure chamber 11 can be provided with a double jacket 21.
