Abstract

Mixing vessel of a stirrer comprises a double skinned pan (1,2) and connecting nozzles (6) to allow passage of a heating or cooling medium. Novelty is that the flow annulus (3) is divided by partitions (4) into vertical segments (5) each possessing two flow connections (6). Jacket segments are preferably of differing sizes to allow matching with operating volume and specific properties required by individual materials and batch sizes. USE/ADVANTAGE - Avoidance of scale up problems, which could lead to crystal deposition, baked-on solids, etc. by provision of a stepwise variable, jacketted heat transfer area.

Description

Die Erfindung betrifft einen Rührbehälter für ein Rührwerk, mit einem Doppelmantel zum Durchfluß eines Heiz- oder Kühlmediums und Anschluß­ stutzen dafür.The invention relates to a stirred tank for an agitator, with a Double jacket for the flow of a heating or cooling medium and connection for that.

Bei verfahrenstechnischen Operationen, bei denen Wärmeenergie in die Befüllung eines Rührbehälters zu- oder von dieser abgeführt werden soll, spielt für die entsprechend zu wählende Temperaturdifferenz zwischen Behälteroberfläche und -inhalt das Verhältnis zwischen der Wärmeaustauschfläche und dem Behälterinhalt eine Rolle. Ferner sind dafür die spezifischen Stoffdaten und der Befüllungsgrad maßgebend. Dabei ist von Bedeutung, wann beim Aufheizen Anbackungen an der Be­ hälterwand durch Kristallisationen oder Vercrackungen entstehen.In procedural operations in which thermal energy in the Filling a stirring container to be supplied or removed from this should play for the temperature difference to be selected accordingly between the surface and contents of the container the ratio between the Heat exchange surface and the container content matter. Furthermore are the specific substance data and the degree of filling are decisive. It is important to know when caking on the Be container wall are formed by crystallization or cracking.

Schwierigkeiten bereitet daher die Übertragung (Scale Up) der ge­ wonnenen Erkenntnisse auf größere Rührbehälter, z. B. für einen Pro­ duktionsbetrieb.The transmission (scale up) of the ge gained knowledge on larger stirred tanks, e.g. B. for a pro production.

Dementsprechend liegt vorliegender Erfindung die Aufgabe zugrunde, einen Rührbehälter für ein Rührwerk zu entwickeln, der unabhängig von den spezifischen Stoffeigenschaften und vom Befüllungsgrad einen Sca­ le Up auf größere Rührbehälter ermöglicht.Accordingly, the present invention is based on the object to develop a stirred tank for an agitator that is independent of the specific material properties and the degree of filling a Sca Le Up allows for larger stirred tanks.

Zur Lösung der Aufgabe ist beim Rührbehälter der eingangs geschil­ derten Art der durch den Doppelmantel gebildete Ringraum durch Zwischenwände in senkrecht verlaufende Segmente unterteilt, von denen jedes zwei Anschlußstutzen aufweist.To solve the problem is the beginning of the stirred tank most kind of the annular space formed by the double jacket Partitions divided into vertical segments, of which each has two connecting pieces.

Weitere Einzelheiten und Vorteile der Erfindung sind anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels nach­ folgend beschrieben.Further details and advantages of the invention are based on an in the drawing schematically illustrated embodiment described below.

Es zeigenShow it

Fig. 1 den Rührbehälter im Querschnitt, Fig. 1 the stirred tank in cross-section,

Fig. 2 den Rührbehälter im Längsschnitt. Fig. 2 shows the stirred tank in longitudinal section.

Wie in den Fig. 1 und 2 zu sehen ist, besteht der Rührbehälter aus einem inneren Mantel 1 und einem äußeren Mantel 2, zwischen denen ein Ringraum 3 zum Durchfluß eines Heiz- oder Kühlmediums gebildet ist. Der Innenraum des inneren Behälters 1 ist zur Aufnahme eines Rührwerks vorgesehen. Gemäß der Erfindung ist der Ringraum 3 durch Zwischenwän­ de 4 in senkrecht verlaufende Segmente 5 unterteilt, von denen jedes Segment zwei Anschlußstutzen 6 aufweist (Fig. 2). Es ist zweckmäßig, die um den Behälterumfang verteilten Segmente in ihrem Volumen unter­ schiedlich auszuführen (Fig. 1). Durch Wahl der Anzahl und Größe der Segmente ist die Möglichkeit gegeben, das Verhältnis zwischen der Wärmeaustauschfläche und dem Behälterinhalt größerer Behälter einzu­ stellen; d. h. es können die gleiche Temperaturdifferenz eingestellt und die gleichen Wärmeträger verwendet werden wie beispielsweise bei einem Produktionsrührbehälter. Der Füllungsgrad muß dabei nicht be­ rücksichtigt werden.As can be seen in FIGS. 1 and 2, the stirred tank consists of an inner jacket 1 and an outer jacket 2 , between which an annular space 3 is formed for the flow of a heating or cooling medium. The interior of the inner container 1 is provided for receiving an agitator. According to the invention, the annular space 3 is divided by dividing walls 4 into vertically extending segments 5 , each segment of which has two connecting pieces 6 ( FIG. 2). It is expedient to run the segments distributed around the circumference of the container in different volumes ( FIG. 1). By choosing the number and size of the segments, it is possible to set the ratio between the heat exchange surface and the tank contents of larger tanks; ie the same temperature difference can be set and the same heat transfer media can be used as for example in a production stirred tank. The degree of filling does not have to be taken into account.

Durch den vorstehend beschriebenen Rührbehälter der Erfindung werden in vorteilhafter Weise folgende Möglichkeiten erreicht:By the above-described stirred tank of the invention advantageously achieved the following options:

  • - Es können Aufschlüsse über die Anbackungsgefahr bei Kristallisa­ tionen oder Vercrackungen beim Aufheizen bei einem Produktionsbe­ hälter erhalten werden.- It can provide information about the risk of caking at Kristallisa or cracking when heating up in a production facility containers can be obtained.
  • - Änderungen der Stoffeigenschaften, z. B. durch Reaktionen, oder des Befüllungsgrades des Behälters, z. B. durch Zufüllen oder Abdestil­ lieren, haben den gleichen Einfluß wie im Produktionsmaßstab.- Changes in material properties, e.g. B. by reactions, or the Degree of filling of the container, e.g. B. by filling or distilling have the same influence as on the production scale.
  • - Eine im Labor erstellte Prozeßablaufsteuerung kann bei kompatiblen Systemen ohne Modifikationen per Datenträger in das Prozeß­ leitsystem der Produktion übertragen werden.- A process flow control created in the laboratory can be used with compatible Systems without modifications in the process using data carriers control system of production.
  • - Durch die gleichen Zeit- und Temperaturdifferenzverhältnisse zum Kühlen oder Aufheizen wird für zeit- und/oder temperaturkritische Verfahren der gleiche Reaktionsmechanismus wie im Produktionsbe­ trieb erhalten.- By the same time and temperature difference ratios to Cooling or heating up is time and / or temperature critical Process the same reaction mechanism as in the production area drive received.
