Abstract
Description
Die Erfindung betrifft eine Hydrozyklonanlage mit mehreren Hydrozyklonen gemäß dem
Oberbegriff des Anspruchs 1.The invention relates to a hydrocyclone system with several hydrocyclones according to the
Preamble of
Bekanntlich werden Hydrozyklone verwendet, um Flüssigkeiten, in denen sich Stoffe von unterschliedlichem Sinkverhalten befinden, durch starke Zentrifugalkräfte zu fraktionieren. So ist es z.B. möglich, die in einer Faserstoffsuspension, wie sie zur Erzeugung von Papier verwendet wird, enthaltenen Störstoffe aufzukonzentrieren und durch einen Rejektanschluss aus dem Hydrozyklon abzuleiten. Die von Störstoffen befreite Fraktion, nämlich der Gutstoff, wird durch den Gutstoffanschluss geführt und weiter verwendet. Diese Vorgänge sind an sich bekannt, ebenso die Tatsache, dass ein guter Effekt nur gewährleistet ist, wenn die Hydrozyklone eine bestimmte Größe nicht überschreiten. Bei einer Hydrozyklonanlage, die für größere Durchsatzmengen ausgelegt ist, wird daher eine Mehrzahl - oft sogar eine Vielzahl - von Hydrozyklonen benötigt. Diese werden dann parallel von der zu reinigenden Flüssigkeit durchströmt, was bedeutet, dass der Flüssigkeitsstrom in eine Vielzahl von kleineren Teilströmen aufgeteilt werden muß. Hierzu können z.B. Verteilvorrichtungen, wie sie im folgenden noch beschrieben werden, verwendet werden.As is known, hydrocyclones are used to move liquids containing substances from different sinking behavior due to strong centrifugal forces fractionate. So it is e.g. possible in a pulp suspension, as used for Production of paper is used to concentrate and contain contaminants derived from the hydrocyclone by a reject connection. That of contaminants The exempt fraction, namely the accept, is led through the accept connection and further used. These processes are known per se, as is the fact that a good effect is only guaranteed if the hydrocyclones are not of a certain size exceed. In the case of a hydrocyclone system designed for larger throughputs is designed, therefore, a plurality - often even a large number - of hydrocyclones needed. The liquid to be cleaned then flows through them in parallel, which means that the liquid flow into a variety of smaller sub-flows must be divided. For this, e.g. Distribution devices, as follows still to be used.
So ist aus der EP-A2-0 563 523 eine Hydrozyklonanlage bekannt. Die darin verwendeten Hydrozyklone sind an ein waagerecht liegendes Strömungsteil angeschlossen, das durch eine sich in Strömungsrichtung erstreckende Trennwand geteilt ist. So bildet sich eine Zulaufkammer und eine Gutstoffkammer.A hydrocyclone system is known from EP-A2-0 563 523. The one in it The hydrocyclones used are on a horizontal flow section connected by a partition extending in the direction of flow is divided. An inlet chamber and an accept material chamber are thus formed.
Eine zweckmäßige Verteilvorrichtung ist in der Regel so zu erstellen, dass die Verteilung der Flüssigkeitsströme gleichmäßig ist. Außerdem sollen hydraulische Störungen, Wirbel oder ähnliches vermieden werden. Eine weitere Anforderung an Hydrozyklonanlagen dieser Art ist ihre Einfachheit, um sie kostengünstig herstellen zu können. Auch sollen die Hydrozyklone zu Wartungszwecken gut zugänglich und leicht zu tauschen sein. Die Erfüllung aller dieser Forderungen ist bei den bisher vorhandenen Anlagen nicht befriedigend gelöst. A suitable distribution device is usually to be created so that the Distribution of liquid flows is even. In addition, hydraulic Disruptions, eddies or the like can be avoided. Another requirement Hydrocyclone plants of this type is their simplicity to manufacture them at low cost can. The hydrocyclones should also be easily accessible and easy to maintain for maintenance purposes to be swapped. The fulfillment of all these requirements is with the existing ones Systems not solved satisfactorily.
Aus der EP 0 658 648 A ist eine Anlage bekannt, bei der eine Anzahl von Hydrozyklonen um einen hydraulischen Schwingungsdämpfer etwa sternförmig angeordnet ist. Der Schwingungsdämpfer ist bekanntlich aufwendig zu bauen und zu betreiben. Auch eine andere in der US 4,267,048 gezeigte Anlage ist kompliziert und erfordert einen hohen Aufwand bei der Herstellung und Montage.A system is known from EP 0 658 648 A in which a number of hydrocyclones is arranged approximately in a star shape around a hydraulic vibration damper. The Vibration dampers are known to be complex to build and operate. Also one other equipment shown in US 4,267,048 is complicated and requires a high one Manufacturing and assembly costs.
Der Erfindung liegt daher die Aufgabe zu Grunde, eine Hydrozyklonanlage zu schaffen, bei der mit einfachen Mitteln eine gleichmäßige Verteilung der zu behandelnden Flüssigkeit auf die Hydrozyklone erfolgen kann.The invention is therefore based on the object of creating a hydrocyclone system, with the simple distribution of an even distribution of those to be treated Liquid can be applied to the hydrocyclones.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 genannten Maßnahmen
gelöst.This object is achieved by the measures mentioned in the characterizing part of
Die erfindungsgemäß gestaltete Verteilvorrichtung enthält z.B. ein relativ großes zylindrisches Rohr oder ein ovales Strömungsteil. Dieses wird durch die beschriebene Trennwand in einen Zulauf- und in einen Gutstoffraum oder in anderen Fällen in einen Zulauf- und in einen Rejektraum geteilt. Das Strömungsteil mit der Trennwand kann leicht als fertig montierte Einheit erstellt und anschließend mit den Öffnungen für die Hydrozyklon-Anschlüsse versehen werden. In der Praxis ist das von großem Vorteil, da die Einbringung zweier für einen Hydrozyklon vorgesehenen Öffnungen in einem Arbeitsvorgang erfolgen kann, also ohne Versetzen des Werkzeuges (z.B. des Laser-Schneiders). Maßabweichungen sind dann sehr viel geringer als bei Schneidern an getrennten Rohrleitungen.The distribution device designed according to the invention contains e.g. a relatively large one cylindrical tube or an oval flow part. This is described by the Partition into an inlet and an accept material room or in other cases in one Inlet and divided into a reject space. The flow part with the partition can easily created as a fully assembled unit and then with the openings for the Hydrocyclone connections are provided. In practice this is of great advantage because the introduction of two openings for a hydrocyclone in one Operation can take place, i.e. without moving the tool (e.g. the Laser cutter). Dimensional deviations are then much smaller than with tailors on separate pipes.
Aus dem Zulaufraum wird die anströmende Flüssigkeit, z.B. eine Faserstoffsuspension, gleichmäßig auf die angeschlossenen Hydrozyklone verteilt. Mit dieser einfachen Maßnahme ist die mengengleiche Versorgung der einzelnen Hydrozyklone möglich. Das gilt besonders, wenn gleiche Hydrozyklone gleichmäßig am Umfang des Strömungsteiles angeordnet sind. Das Zurückströmen in den stromabwärts der Trennwand gelegenen Raum der Verteilvorrichtung erfolgt mit Vorteil durch den Leichtstoffanschluss des Hydrozyklons. Dieser liegt in den meisten Fällen nahe dem Zulaufanschluss.The inflowing liquid, e.g. a fiber suspension, evenly distributed over the connected hydrocyclones. With this simple Measure is the equal supply of the individual hydrocyclones possible. The applies especially if the same hydrocyclones are evenly distributed around the circumference of the flow section are arranged. The backflow into the downstream of the partition The space of the distribution device is advantageously provided by the light material connection of the Hydrocyclone. In most cases this is close to the inlet connection.
In speziellen vorteilhaften Ausgestaltungen können die Anschlüsse zwischen dem Strömungsteil und den Hydrozyklonen als abgedichtete Steckverbindungen ausgeführt sein. Das läßt eine leichte Montage bzw. ein leichtes Auswechseln von Hydrozyklonen zu. Außerdem ist diese Art der Verbindung kostengünstig. Der Aufbau der Anlage ist einfach und übersichtlich. Es ist auch leicht möglich, den Hauptstrom der Flüssigkeiten in seiner Richtung beizubehalten; d.h. dass Zulaufstrom und Gutstoff- bzw. Rejektstrom die gleiche Richtung haben.In special advantageous configurations, the connections between the Flow part and the hydrocyclones executed as sealed plug connections his. This allows easy assembly or replacement of hydrocyclones. This type of connection is also inexpensive. The structure of the system is simple and clear. It is also easily possible to keep the main stream of liquids in maintain its direction; i.e. that the inflow and the accept or reject flow have the same direction.

Die in der Fig. 1 gezeigte Hydrozyklonanlage erhält die zu reinigende Suspension durch
eine große Zulaufleitung, welche in die Verteil- und Sammelvorrichtung 5 von unten
einmündet. Diese besteht im wesentlichen aus einer zylindrischen Seitenwand 7 und ist
durch eine Trennwand 9 quer zur Strömungsrichtung geteilt. Stromaufwärts zu dieser
Trennwand 9, d.h. also zulaufseitig, befindet sich eine Anzahl von Öffnungen 11 zur
Aufnahme der Zulaufanschlüsse 2 der seitlich zur Verteil- und Sammelvorrichtung 5
angeordneten Hydrozyklone 1. In dieser Figur ist lediglich einer der Hydrozyklone 1
gezeichnet. In der Regel sind die Hydrozyklone 1, die bei einer solchen Anlage verwendet
werden, untereinander gleich. Der Hydrozyklon 1 enthält eine Mittelachse 10, welche
parallel zur zylindrischen Seitenwand 7 und damit zur Strömungsrichtung 6 angeordnet
ist. Der Hydrozyklon 1 ist so aufgebaut, dass die Leichtteil-Fraktion als Gutstoff über
den Gutstoffanschluss 3 abgeführt wird. Die dazu dienenden Öffnungen 12 in der
zylindrischen Seitenwand 7 befinden sich stromabwärts der Trennwand 9. An dieser
Stelle ist die Seitenwand 7 geschnitten gezeichnet. Die Mittellinien 18 des
Zulaufanschlusses 2 und die Mittellinie 19 des Gutstoffanschlusses 3 liegen hier in
zueinander parallelen Ebenen, die wiederum senkrecht zur Strömungsrichtung 6 in der
Verteil- und Sammelvorrichtung 5 stehen. Das führt zu einem besonders einfachen
Aufbau der Verteil- und Sammelvorrichtung 5, und die Öffnungen 11 und 12 können
leicht angebracht werden. Die Ebenen haben einen relativ geringen Abstand 20,
vorzugsweise nicht mehr als 1,5 m. Man erkennt auch, dass die Öffnungen 11 und 12
jeweils auf demselben Umfang 13 bzw. 14 angeordnet sind. Dort wo der Hydrozyklon in
die Öffnungen 11, 12 mündet, sind elastische Dichtelemente 15 eingesetzt. Zu seiner
mechanischen Befestigung dient ein nur angedeuteter Halter 17. Diese Form erspart z.B.
verschraubte Flansche und ermöglicht es außerdem, die nicht ganz auszuschließenden
Toleranzen bei der Herstellung der Hydrozyklone bzw. Hydrozyklonanlage auszugleichen.
Die Rejekt-Fraktion, also die Schwerteile, werden durch den Rejektanschluss 4 in eine
Rejektleitung 16 abgeleitet.The hydrocyclone system shown in FIG. 1 receives the suspension to be cleaned
a large feed line, which in the distribution and
Der in Fig. 1 gezeigte Aufbau der Hydrozyklonanlage ist besonders einfach. Es sind aber
ohne weiteres Abweichungen von dieser Anordnung vorstellbar. So kann z.B. die
Verteilvorrichtung auch oval sein oder einen polygonförmigen Grundriss haben. Es ist
auch denkbar, die Trennwand 9 schräg anzuordnen, so dass sie einen Winkel α zur
Strömungsrichtung 6 bildet, der von 90° abweicht. In diesem Falle liegen die Öffnungen
11 bzw. 12 mit Vorteil auf gedachten Ebenen, die parallel zur Trennwand 9 sind.The construction of the hydrocyclone system shown in FIG. 1 is particularly simple. But there are
deviations from this arrangement are easily conceivable. For example, the
Distribution device can also be oval or have a polygonal plan. It is
also conceivable to arrange the
Die Figur 2 zeigt schematisch eine erfindungsgemäße Hydrozyklonanlage in Ansicht von
oben. Das Prinzip der vorgelegten Erfindung ermöglicht eine sehr einfache gleichmäßge
Verteilung der Flüssigkeiten dadurch, dass die Hydrozyklone 1 strahlenförmig mit
gleichem Abstand um die hier zylindrische Seitenwand der Verteilvorrichtung herum
angeordnet sind. Die hier nicht sichtbare Trennwand liegt waagerecht zwischen den
Zulaufanschlüssen 2 und den Gutstoffanschlüssen 3.FIG. 2 schematically shows a hydrocyclone system according to the invention in a view from
above. The principle of the presented invention enables a very simple even
Distribution of the liquids in that the
Hydrozyklone können auch so eingesetzt werden, daß die Schwerfraktion als Gutstoff und die Leichtfraktion als Rejekt verwendet wird. Mit einer solchen Anwendung werden z.B. spezifisch leichte Störstoffe aus einer Papierfasersuspension abgeschieden. Auch hierzu kann eine erfindungsgemäße Anlage verwendet werden, indem der Gutstoffanschluss (3) der Fig. 1 oder 2 als Rejektanschluss dient. Der Gutstoff fällt dann am Auslass für die Schwerfraktion an. Solche Schaltungen sind an sich bekannt und daher hier nicht speziell dargestellt.Hydrocyclones can also be used so that the heavy fraction as a good substance and the light fraction is used as a reject. With such an application e.g. Specifically light contaminants separated from a paper fiber suspension. Here too A system according to the invention can be used in that the accept material connection (3) 1 or 2 serves as reject connection. The accepted material then falls at the outlet for the Heavy fraction. Such circuits are known per se and therefore not here specially illustrated.
