Description
Vorrichtung zur Schaumzerstörung in Flüssigkeitsverdampfern Zur Trennung der Brüden von Flüssigkeit in Verdampfern werden entweder große Behälter über den Heizkörpern angeordnet oder das Brüdenflüssigkeitsgemisch wird tangential in gesondert angeordnete D ampfabscheider eingeleitet.Device for foam destruction in liquid evaporators For separation The vapors of liquid in evaporators are either large containers over the Arranged radiators or the vapor liquid mixture is tangential in separate arranged vapor separator initiated.
Werden stark schäumende Flüssigkeiten, wie z. B. Are strongly foaming liquids such. B.
Milch, eingedampft, so muß der freie Raum über dem Heizkörper bzw. der Dampfabscheider so groß sein, daß diese Behälter den »stehenden« Schaum aufnehmen können, ohne daß dieser den Stutzen zum Kondensator erreicht und somit nicht durch denselben abgesaugt wird. Bei Eindampfung einer Flüssigkeit unter Vakuum müssen die Behälter größere Wandstärken aufweisen als solche für Normaldruckverdampfung. Für eine Anlage aus Edelstahl oder ähnlichen Baustoffen bedeutet dies eine wesentliche Verteuerung, wenn man nicht zur Versteifung des Verdampfermantels einen Winkelring ein- oder aufsetzt. Überall dort, wo aus Gründen der Sa.uberhaltung glatte Innenwände angestrebt werden, ist ein innerer Verstärkungsring unerwünscht.Milk, evaporated, the free space above the radiator or the vapor separator must be so large that these containers take up the "standing" foam can without this reaching the nozzle to the condenser and thus not through the same is sucked off. When evaporation of a liquid under vacuum must the containers have greater wall thicknesses than those for normal pressure evaporation. For a system made of stainless steel or similar building materials, this means an essential one More expensive if you do not use an angle ring to stiffen the evaporator jacket in or out. Wherever there are smooth interior walls for reasons of cleanliness are desired, an inner reinforcing ring is undesirable.
Es ist bekannt, daß Schaumblasen an gekühlten Wänden zusammenfallen. Erfindungsgemäß wird daher vorgeschlagen, etwa in der Mitte des Verdampfermantels oder des Dampfabscheiders einen eingeschweißten Ring vorzusehen, der zur Versteifung des Mantels und zum Hindurchleiten eines Kühlmittels dient. It is known that foam bubbles collapse on cooled walls. According to the invention it is therefore proposed approximately in the middle of the evaporator jacket or the steam separator to provide a welded-in ring for stiffening of the jacket and is used to pass a coolant.
Vorzugsweise wird ein Rohrring in den Verdampfer bzw. Dampfabscheider so eingesetzt, daß der obere Mantelteil desselben an dem inneren Durchmesser und der untere Mantelteil an dem äußeren Durchmesser des Rohrringes tangiert. Die innenliegenden Schweißnähte werden glattgeschliffen, wodurch Schmutzecken vermieden werden. Der durch den Rohrring entstehende Absatz begrenzt das Hochziehen des Flüssigkeitsschaumes an der Wandung, wodurch verhütet wird, daß der Schaum die Kühlzone übersteigt. A pipe ring is preferably inserted into the evaporator or vapor separator inserted so that the upper shell part of the same to the inner diameter and the lower shell part is tangent to the outer diameter of the tubular ring. The inside Weld seams are ground smooth, which avoids dirty corners. Of the The shoulder created by the pipe ring limits the pulling up of the liquid foam on the wall, which prevents the foam from exceeding the cooling zone.
Durch diese Maßnahme wird weiterhin erreicht, daß die Bauhöhe des Dampfabscheiders verringert werden kann.This measure also ensures that the overall height of the Steam separator can be reduced.
Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar. Es zeigt Fig. A einen Verdampfer mit oberem Dampfabschei deraum, Fig. B einen an einen Erhitzer seitlich anzuschließenden Dampfabscheider. The drawing shows an embodiment of the invention. It Fig. A shows an evaporator with an upper steam separating room, Fig. B one to one Heater to be connected to the side of the steam separator.
In Fig. A ist i das Heizsystem und 2 der darüber angeordnete Dampfabscheideraum, dessen Mantel bei 3 einen Kühlrohrring erhält. Bei 4 tritt die zu verdampfende Flüssigkeit ein, und bei 5 strömen die Brüden zum Kondensator. In Fig. A i is the heating system and 2 is the vapor separation room above, whose jacket at 3 receives a cooling tube ring. At 4 comes the liquid to be evaporated on, and at 5 the vapors flow to the condenser.
Fig. B zeigt einen vom Heizsystem getrennten Dampfabscheider 6, an dessen abgestuftem Mantel bei 7 ein Kühlrohr vorgesehen ist. 8 ist der Eintritt des Brüdenflüssigkeitsgemisches. Bei 9 fließt die nicht verdampfte Flüssigkeit in den Erhitzer zurück, während bei 10 die Brüden in den Kondensator entweichen. FIG. B shows a vapor separator 6 that is separate from the heating system the stepped jacket of which a cooling tube is provided at 7. 8 is entry of the vapor liquid mixture. At 9, the non-evaporated liquid flows into the heater back, while at 10 the vapors escape into the condenser.
In Fig. A und B schließen sich die Mantelteile 2, 2a bzw. 6, 6 a tangential an den Kühlring 3 bzw. 7 an. In Fig. A and B, the shell parts 2, 2a and 6, 6 a close tangentially to the cooling ring 3 or 7.
PATENTANSPR8CHE 1. Vorrichtung zur Schaumzerstörung in Verdampfern, bei denen die Dampfabscheider entweder unmittelbar über dem Flüssigkeitserhitzer oder seitlich von demselben angeordnet sind, dadurch gekennzeichnet, daß in den abgestuften Dampfabscheidermantel (2, 2 a bzw. 6, 6a) ein der Kühlung der Schaumblasen sowie gleichzeitig der Versteifung des Mantels dienender Rohrring (3 bzw. 7) angeschweißt ist. PATENT CLAIM 1. Device for foam destruction in evaporators, where the vapor separator is either directly above the liquid heater or are arranged to the side of the same, characterized in that in the stepped vapor separator jacket (2, 2 a or 6, 6a) to cool the foam bubbles and, at the same time, the tubular ring (3 or 7) serving to stiffen the jacket is.
