Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft einen Kesselspeisewasser-Erhitzer und -Reiniger, in welchem das Wasser in Röhren hochsteigt, die von Dampf umspült werden. In bekannten derartigen Vorrichtungen wird das in den Röhren hochsteigende Wasser dort zunächst vorgewärmt, um dann über den oberen Rand der Röhren herabzufließen.The invention relates to a boiler feed water heater and cleaner in which the Water rises in pipes that are washed by steam. In known such Devices, the water rising in the pipes is first preheated there, to then flow down over the top of the tubes.

Um bei einem solchen Kocher eine mögliehst feine Zerteilung des Wassers in Schichten zu erreichen, wird gemäß der Erfindung das Wasser nach seinem Austritt aus dem oberen Ende der Röhren gezwungen, auf den Flächen von zwischen den Röhren angeordneten Tafeln aus Blech o. dgl. entlang zu laufen, die mit Vorsprüngen in Löcher der die Röhren oben abschließenden Rohrplatte greifen. Beim Herablaufen des Wassers, das sich beim Hochsteigen in den Röhren schon vorgewärmt hat, an den zwischen den Röhren angeordneten und ebenso wie diese vom Dampf umspülten Tafeln wird es so gründlich abgekocht, daß eine nahezu vollständige Ausscheidung der Kesselsteinbildner stattfindet, die sich zum großen Teil an den Blechtafeln absetzen. Da die Blechtafeln leicht herausnehmbar sind, kann der Kesselstein leicht entfernt werden. Der sich nach dem Durch- : fließen des Kochers noch ausscheidende Kesselstein wird durch einen Klärbehälter nach einem Schlammsammler geführt, aus dem er in bekannter Weise durch einen Schlammablaßhahn entfernt werden kann.In order to achieve the finest possible division of the water into layers in such a cooker, according to the invention the water is forced, after it emerges from the upper end of the tubes, on the surfaces of sheets of sheet metal or the like arranged between the tubes run, which grip with projections in holes of the tubes at the top of the tube plate. When the water runs down, which has already warmed up in the tubes when it rises, it is boiled so thoroughly on the panels arranged between the tubes and washed around them by the steam that the scale-forming agents are almost completely eliminated, most of which are removed set it down on the metal panels. Since the metal sheets are easily removable, the scale can be easily removed. Which according to the throughput: flow of the digester still secreting scale is passed through a septic tank to a sludge collector, from which it can be removed by a sludge drain valve in a known manner.

Die Zeichnung zeigt die Erfindung in einem Ausführungsbeispiel in Fig. 1 im senkrechten Schnitt und in Fig. 2 in Ansicht auf die Rohrplatte.The drawing shows the invention in an exemplary embodiment in FIG. 1 in the vertical Section and in Fig. 2 in a view of the tube plate.

In das unten trichterförmig gestaltete Gehäuse α ist nach bekannter Anordnung eine Schale b mit einer sie oben abdeckenden'Rohrplatte c eingesetzt. Die Schale b mündet in bekannter Weise mit einem Stutzen in den Wasserzulaufstutzen d. Die Röhren f zum Hochleiten des Wassers sind mit ihren oberen Enden in der Rohrplatte g befestigt, die schalenförmig gestaltet ist. Diese Rohrplatte ist zwischen den Mündungen der Röhren mit Lochreihen h versehen, und zwischen die Röhrenreihen sind gemäß der Erfindung Blechtafeln i eingesetzt, die mit Zacken oder Vor-Sprüngen in die Löcher h der Rohrplatte g greifen. Die Blechtafeln i enden in einem bestimmten Abstand über der unteren Rohrplatte c, so daß das durch den Stutzen d eingeleitete und durch die Schale b sowie die Röhren f hochsteigende Wasser nach seinem Durchtritt durch die Löcher h, und nachdem es an den Blechtafeln i nach unten gelaufen ist, seitlich der Schale b durch den Stutzen k in den Schlammsammler I fließen kann, aus dem es dann in den Kessel geleitet wird. Der Dampf tritt in das Gehäuse α durch den. Stutzen m ein.According to a known arrangement, a shell b with a tubular plate c covering it at the top is inserted into the housing α , which is funnel-shaped at the bottom. The shell b opens in a known manner with a nozzle in the water inlet nozzle d. The upper ends of the tubes f for guiding the water upward are fastened in the tube plate g , which is designed in the shape of a bowl. This tube plate is provided with rows of holes h between the mouths of the tubes, and between the rows of tubes, according to the invention, metal sheets i are inserted which engage with prongs or protrusions into the holes h of the tube plate g. The metal sheets i end at a certain distance above the lower tube plate c, so that the water which is introduced through the nozzle d and rises through the shell b and the tubes f after its passage through the holes h and after it has passed down the metal sheets i has run, the side of the shell b can flow through the nozzle k into the sludge collector I , from which it is then passed into the boiler. The steam enters the housing α through the. Stutzen m a.
