Description

Fliehkraft -Tropfenabscheider für Dünnschichtverdampfer Die Erfindung betrifft eine Vorrichtung zum Abscheiden von mitgerissenen Flüssigkeitströpfchen bei Verdampfern, insbesondere Dünnschichtverdampfern.Centrifugal droplet separator for thin-film evaporators The invention relates to a device for separating entrained liquid droplets in evaporators, especially thin-film evaporators.

In solchen Apparaten, bei denen die Flüssigkeit an der Innenseite eines senkrecht stehenden Zylinders in dünner Schicht herunterrieselt und an der als Heizfläche ausgebildeten Zylinderfläche verdampft, werden leicht Tropfen der Flüssigkeit mitgerissen und verunreinigen das Destillat.In such apparatus where the liquid is on the inside of a vertical cylinder trickles down in a thin layer and on the formed as a heating surface cylinder surface evaporates, easily drops of the Entrained liquid and contaminate the distillate.

Es ist schon bekannt, die Tropfen durch einen eingebauten Boden, der aus Prallblechen besteht, oder durch Raschigringe, die auf einem Rost liegen, abzuscheiden. Dabei fallen jedoch die Tropfen an den Stellen, wo sie sich sammeln, also über den ganzen Querschnitt verteilt, herunter und fallen infolgedessen auf den Boden des Verdampfers und vermischen sich mit dem von dem leicht siedenden befreiten Rückstand. It is already known that the drops through a built-in floor, which consists of baffle plates, or by means of Raschig rings that lie on a grate, to be deposited. However, the drops fall at the points where they collect, So distributed over the entire cross-section, fall down and are therefore noticeable the bottom of the evaporator and mix with the freed from the low-boiling Residue.

Es wurde nun gefunden, daß dieser Nachteil vermieden wird und eine sehr vollkommene Reinigung der Dämpfe erzielt wird, wenn man den Abscheider als um seine eigene Achse rotierenden Korb ausbildet, der mit Füllkörpern gefüllt ist. It has now been found that this disadvantage is avoided and one very perfect cleaning of the vapors is achieved if the separator is used as a forms rotating basket around its own axis, which is filled with random packings.

Dadurch werden die abgefangenen Tröpfchen nach außen geschleudert und gelangen an die Wand, an der sie in dünner Schicht herunterlaufen und der Heizfläche wieder zufließen. This hurls the captured droplets outwards and reach the wall, on which they run down in a thin layer, and the heating surface flow again.

In der Zeichnung sitzt auf der senkrechten Welle 1 eine Nabe 2, die einen Rost 3 trägt. Dieser Rost trägt einen Zylinder 4, der aus durchlöchertem Blech oder Siebmaterial besteht. Der Korb wird durch einen als Rost oder Siebplatte ausgebildeten Deckel 5 abgeschlossen. Der Zylinder rotiert in geringem Abstand innerhalb des zylindrischen Abzugsrohres 6. Die innerhalb des Korbes abgeschiedene Flüssigkeit gelangt durch den durchlochten Zylinder 4 an die Wand des Abzugsrohres 6 und läuft an dieser dem darunter angebrachten Verdampfer 7 wieder zu. In the drawing, a hub 2 sits on the vertical shaft 1, which a grate 3 carries. This grate carries a cylinder 4 made of perforated sheet metal or sieve material. The basket is designed as a grate or sieve plate Cover 5 completed. The cylinder rotates a short distance inside the cylindrical one Exhaust pipe 6. The liquid separated inside the basket passes through the perforated cylinder 4 on the wall of the exhaust pipe 6 and runs on this The evaporator 7 attached underneath it closes again.

Diese Einrichtung kann natürlich auch in jede beliebige Dampfabzugsleitung eingebaut werden, bei der es darauf ankommt, die Dämpfe von mitgerissenen Flüssigkeitströpfchen zu befreien. Das Rohr kann in solchen Fällen auch waagerecht liegen. This device can of course also be used in any steam extraction line built in, where it comes down to the vapors from entrained liquid droplets to free. In such cases, the pipe can also lie horizontally.

Diese Ausführung eignet sich besonders gut für Dünnschichtverdampfer, bei denen die Verteilung der Flüssigkeit auf der senkrechten, zylindrischen Heizfläche durch Wischer oder Bürsten bewerkstelligt wird. This version is particularly suitable for thin-film evaporators, where the distribution of the liquid on the vertical, cylindrical heating surface is accomplished by wiping or brushing.
