Description

Mischvorwärmer, bei dem das vorzuwärmende Wasser im Gegenstrom zum Dampf über einen mit Rieselkörpern gefüllten Einsatzkasten geführt wird Bei Mischvorwärmern, deren Rieselflächen aus einer Füllung von Metallkörpern bestehen, bildet sich an den Rieselkörpern Kesselstein. Diese Kesselsteinbildung ist so bedeutend, daß die ganze Füllmasse zu einem Körper zusammenwächst. Eine Entfernung der Metallrieselkörper aus dem Mischvorwärmergehäuse ist nur mit Gewalt möglich, da die gesamten Rieselkörper herausgehauen werden müssen, was Zeit und Geld kostet. Es ist zwar schon vorgeschlagen worden, die Rieselkörper im Vorwärmergehäuse in einem auswechselbaren Kasten anzuordnen, jedoch besteht dieser Kasten aus Siebblechen, so daß ein Zusammenwachsen mit dem Gehäuse nicht sicher vermieden "wird.Mixing preheater, in which the water to be preheated in countercurrent to the Steam is passed over an insert box filled with trickle particles. whose flow surfaces consist of a filling of metal bodies, forms the trickle bodies limestone. This scale formation is so important that the whole filling mass grows together to form a body. Removal of the metal trickles from the mixer preheater housing is only possible with force, as the entire trickle body have to be cut out, which costs time and money. It has already been suggested been to arrange the trickle bodies in the preheater housing in an exchangeable box, However, this box consists of sieve plates, so that it grows together with the Housing not safely avoided ".

Um diesen Übelstand zu beseitigen, werden die Rieselkörper erfindungsgemäß in eine Anzahl Kästen eingefüllt, die den Querschnitt des Innenraumes des Vorwärmers ausfüllen. Die einzelnen Kästen sind nur unten und oben offen, und über dem zwischen den Kästen verbleibenden freien Raum sind Abdeckleisten gegen Durchfluß von Dampf und Wasser vorgesehen. Es wird dadurch erreicht, daß die Kesselsteinbildung nur innerhalb der Kästen eintreten kann und ein Zusammenbacken der Kästen untereinander und mit dem Vorwärmergehäuse verhindert wird.In order to eliminate this drawback, the trickle bodies are according to the invention filled in a number of boxes, which are the cross-section of the interior of the preheater to complete. The individual boxes are only open at the bottom and top, and above the one in between The free space remaining in the boxes are cover strips to prevent the flow of steam and water provided. It is achieved that the scale formation only can occur inside the boxes and caking of the boxes with one another and is prevented with the preheater housing.

Durch die Unterteilung des Innenraumes des Vorwärmers mittels der Kästen und durch Schutz gegen das Zusammenwachsen infolge von Kesselsteinbildung mittels der Abdeckleisten ist eine schnelle und einfache Auswechselung der Rieselkörperkästen möglich.By subdividing the interior of the preheater by means of the Boxes and protection against coalescence as a result of scale formation by means of the cover strips, the trickle body boxes can be exchanged quickly and easily possible.

Die Zeichnung zeigt in den Abb. i und 2 einen Mischvorwärmer mit Rieselkörpern, z. B. mit kaschigringen, in dessen Innenraum i sich die einzelnen Rieselkörperkästen 2 befinden. Die Zwischenräume 3 zwischen den einzelnen Rieselkörperkästen 2 und zwischen den Rieselkörperkästen 2 und dem Vorwärmergehäuse i sind durch die Abdeckleisten q. geschlossen. Der Zutritt des Dampfes erfolgt in bekannter Weise durch das Rohr' 5, während das Wasser in zerteiltem Zustande durch das Rohr 6 in den Mischvorwärmer eintritt.The drawing shows in Figs. I and 2 a mixing preheater with trickle bodies, z. B. with kaschig rings, in the interior of which i are the individual trickle body boxes 2 are located. The spaces 3 between the individual trickle-body boxes 2 and between the trickle body boxes 2 and the preheater housing i are through the cover strips q. closed. The entry of the steam takes place in a known manner through the pipe ' 5, while the water is in a divided state through the pipe 6 into the mixer preheater entry.
