Description

Mischdüse zum mischen von Flüssigkeiten mit Dampf, Gasen u. dgl. Die Erfindung bezieht sich auf Düsen zum Mischen von Flüssigkeiten mit Dampf, Gasen u. dgl. Gegenüber den bekannten Mischdüsen, wie sie z. B. zum Vorwärmen von Speisewasser benutzt werden, besteht das Wesen der Erfindung darin, daß sie aus einem mit Einschnitten versehenen Rohrstück besteht, dessen an den Einschnitten zurückliegenden Teile des Rohrumfanges einwärts gebeult sind.Mixing nozzle for mixing liquids with steam, gases and the like Invention relates to nozzles for mixing liquids with steam, gases and the like. Compared to the known mixing nozzles, as z. B. to preheat feed water are used, the essence of the invention is that it consists of a with notches provided pipe section, the parts of which are located behind at the incisions Are dented inwards around the circumference of the pipe.

Hierdurch wird eine äußerst einfach herzustellende und billige Mischdüse geschaffen. In der Zeichnung ist ein Ausführungsbeispiel, in Abb. r in der Seitenansicht und in Abb. z im Schnitt nach A-B, veranschaulicht. Gemäß der Erfindung besteht die Mischdüse aus einem Rohrstück a, das an seinem Umfange mit Einschnitten b versehen ist. Vorteilhaft werden diese Einschnitte b in der aus Abb. r ersichtlichen Weise versetzt angebracht. Hierauf werden die an den Einschnitten zurückliegenden Umfangsteile c nach innen gebeult.This makes an extremely easy to manufacture and inexpensive mixing nozzle created. In the drawing is an embodiment, in Fig. R in the side view and in Fig. z in section along A-B. According to the invention there is the mixing nozzle from a piece of pipe a, which is provided with incisions b on its circumference is. These incisions b are advantageous in the manner shown in Fig. R offset. The circumferential parts lying back at the incisions are then placed c dented inwards.

Diese Mischdüse ist besonders zweckmäßig z. B. beim Anwärmen von Kesselwasser zu verwenden. In diesem Falle wird in den anzuwärmenden Kessel ein Dampfrohr geleitet, dessen freies Ende mit einer Mischdüse gemäß der Erfindung versehen ist. Der durch die Düse axial hindurchtretende Dampf schlägt sich bei seinem Zusammentreffen mit dem kalten Kesselwasser an den Einschnittsstellen des Düsenrohres nieder, so daß das Kesselwasser beschleunigt durch die Einschnittsstellen b, c in das Innere des Rohres strömt, hier angewärmt und unter dem Einfluß des Dampfes aus dem freien Rohrende ausgetrieben wird. Infolgedessen tritt in dem anzuwärmenden Kesselwasser eine beschleunigte Bewegung ein, so daß das Anwärmen des Kesselwassers in kurzer Zeit vor sich geht und sonst auftretende Schläge vermieden werden.This mixing nozzle is particularly useful for. B. when heating boiler water to use. In this case, a steam pipe is fed into the boiler to be heated, the free end of which is provided with a mixing nozzle according to the invention. The through The steam axially passing through the nozzle is also affected when it meets the cold boiler water down at the incision points of the nozzle pipe, so that the boiler water accelerates through the incision points b, c into the interior of the The pipe flows, warmed here and under the influence of the steam from the free end of the pipe is expelled. As a result, an accelerated rate occurs in the boiler water to be heated Movement in so that the boiler water is heated up in a short time and any other impacts that may occur are avoided.

Selbstverständlich ist die Mischdüse auch für andere Zwecke verwendbar, in denen es darauf ankommt, in Flüssigkeiten oder Gasen entsprechende Umsetzungen oder Mischungen zu erzielen.Of course, the mixing nozzle can also be used for other purposes, in which it is important, appropriate conversions in liquids or gases or to achieve mixtures.
