Zirkulationseinrichtung zur Verhinderung von Siedeverzügen G21 Vorwärmern.
EMI1.1
In der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform
EMI1.2
Fig. 2 dieselbe im Querschnitt.
In die übereinander angeordneten Vorwärmer 1, 2, deren Innenräume durch Stutzen in Verbindung stehen, wird die vorzuwärmende Flüssfigkeit, beispielsweise Rohöl, eingeleitet.
EMI1.3
<Desc/Clms Page number 2>
den unteren Behälter angesaugte kältere Flüssigkeit in ein Rohr 9 drückt, aus welchem sie sich in ein oberhalb des Flüssigkeitsspiegels angeordnetes Rohr 10 ergiesst, welches mit kleinen Öffnungen 11 versehen ist, so dass die Flüssigkeit aus demselben nur in feinen Strahlen bzw. Tropfen austreten kann.
Zu Beginn des Destillationsprozesses wird nur der obere VorwärmeT geheizt. Die Erwärmung der Flüssigkeit würde infolgedessen im oberen und unteren Vorwärmer, in welch letzterem die Rückstände erst nach Beendigung des einen Destillationsprozesses eingeleitet werden können, eine ungleichmässige sein. Durch die Wirkung des Pumpwerkes, welches beständig Flüssigkeit, aus dem unteren Behälter in den oberen überführt, wird aber eine derart wirksame Zirkulation erzielt, dass die Flüssigkeit in allen Teilen des gemeinschaftlichen Raumes die gleiche Temperatur besitzt. Gleichzeitig werden auf diese Weise durch eine beständige Bewegung der Flüssigkeit und infolgedessen ein Erhitzen derselben über den Siedepunkt bzw. eine Verzögerung der Dampfbildung, also Siedeverzüge hintangehalten.
Da der Übertritt der Flüssigkeit aus dem einen Vorwärmer in den anderen durch die Anordnung des mit kleinen Öffnungen versehenen Rohres 10, an dessen Stelle auch Düsen oder dgl. treten können, nur tropfenweise erfolgen kann, so wird auch jeder einzelne Tropfen für sich erwärmt, so dass das in demselben enthaltene Wasser bzw. der in demselben enthaltene Wassertropfen, welcher infolge des spezifischen Gewichtes allseits von Olteilchen umgeben ist, allmählich verdampfen kann, wodurch auch eine Trennung des verdampfenden Wassers vom Öle bewirkt wird.

Circulation device to prevent delays in boiling G21 preheaters.
EMI1.1
The subject matter of the invention is shown in an exemplary embodiment in the drawing
EMI1.2
Fig. 2 the same in cross section.
The liquid to be preheated, for example crude oil, is introduced into the preheaters 1, 2 arranged one above the other, the interiors of which are connected by nozzles.
EMI1.3
<Desc / Clms Page number 2>
Colder liquid sucked in the lower container pushes into a tube 9, from which it pours into a tube 10 arranged above the liquid level, which is provided with small openings 11 so that the liquid can only emerge from the same in fine jets or drops.
At the beginning of the distillation process only the upper preheater T is heated. As a result, the heating of the liquid in the upper and lower preheaters, in which the residues can only be introduced after the end of the one distillation process, would be uneven. Due to the action of the pumping mechanism, which constantly transfers liquid from the lower container to the upper one, however, such an effective circulation is achieved that the liquid has the same temperature in all parts of the common space. At the same time, in this way, constant movement of the liquid and, consequently, heating of the same above the boiling point or a delay in the formation of vapor, i.e. delays in boiling, are prevented.
Since the transfer of the liquid from one preheater to the other through the arrangement of the tube 10 provided with small openings, which can also be replaced by nozzles or the like, can only take place drop by drop, so each individual drop is heated separately that the water contained in the same or the water drop contained in the same, which is surrounded on all sides by oil particles due to the specific gravity, can gradually evaporate, which also causes a separation of the evaporating water from the oil.
