Abstract

A fireproof tubular filter for hot gases is made of a porous rigid ceramic material. To produce the required length, each short tube section is joined to the next by a bush which is packed with an elastic refractory cement. For a radially inward gas flow, the composite tube can rest in a sealed bush on the bottom of the dust laden gas inlet chamber and is secured in the partition to the clean gas chamber by another sealed bush. This overcomes the difficulty of mfg. porous ceramic tubes in greater lengths.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

Feuerfester Filter Um heiße Gase ab zus cheiden, werden vielfach Spezialfilter-Materialien verwendet. Dieses Material besteht z.B. aus gesinterten Metallen und/oder aus vergüteten Glas- oder Keramikfasern. Fireproof filter To separate hot gases, are often Special filter materials used. This material consists e.g. of sintered Metals and / or made of tempered glass or ceramic fibers.

Um eine preiswerte Lösung zu schaffen, wird erfindungsgemäß vorgeschlagen, poröse Hartkeramikrohre zu verwenden, die ohne jegliche Stützkonstruktion als Filterkerzen Anwendung finden können.In order to create an inexpensive solution, it is proposed according to the invention that To use porous hard ceramic tubes without any supporting structure as filter candles Can find application.

Aus technischen Gründen können diese Rartkeramikfilterrohre nicht wunschgerecht in größeren Längen hergestellt werden.For technical reasons, these rare ceramic filter tubes cannot can be produced in greater lengths as required.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, kurze Rohrstücke entsprechend beiliegender Zeichnung als Filter anzuwenden.For this reason, the invention proposes short pieces of pipe to be used as a filter according to the accompanying drawing.

In der beiliegenden Zeichnung ist dargestellt: mit 1) in ein Filtergehäuse-Abschnitt mit 2) die kurzen aufeinandergesteckten Keramikrohre mit 3) Verbindungsbuchsen, in die die Keramikrohre in einfachster Weise eingesteckt werden und mittels elastischen feuerfesten Materials abdichtend in der Buchse gehalten sind.The attached drawing shows: with 1) in a filter housing section with 2) the short stacked ceramic tubes with 3) connecting sockets into which the ceramic tubes are plugged in the simplest possible way and held in a sealing manner in the socket by means of elastic refractory material are.

Der Abschluß zwischen dem Boden und dem Reingaskanal wird ebenfalls erfindungsgemäß durch eine Buchsenabdichtung, die mit feuerfestem elastischem Material gestopft ist, versehen.The seal between the floor and the clean gas duct is also made according to the invention by a bushing seal made with fire-resistant elastic material is stuffed, provided.

Die Reinigung der Rohre erfolgt über bekannte Technologien, z.B. über einen Druckluftstoß - Düse vier - oder normales Gegenspülen.The pipes are cleaned using known technologies, e.g. via a blast of compressed air - nozzle four - or normal counter-rinsing.

Selbstverständlich ist die Erfindung nicht auf die im einzelnen beschriebene und gezeichnete Ausführung beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Heißgasfilter so herzustellen, daß er aus relativ kurzen porösen Rohren besteht, die aus den verschiedensten Materialien hergestellt und gasdurchlässig sind und mit kurzen Verbindungsbuchsen 3), die mit elastischem feuerfestem Material abdichtend, vorzugsweise konisch selbstarretierend ausgebildet, die einzelnen porösen Rohre verbinden, diese in einer Einheit beliebiger Höhe herstellen.Of course, the invention is not limited to that described in detail and drawn execution limited, but numerous modifications are possible, However, without deviating from the basic idea of manufacturing a hot gas filter in such a way that that it consists of relatively short porous tubes made of a wide variety of Materials are made and gas permeable and with short connecting sockets 3), sealed with elastic refractory material, preferably conical self-locking designed to connect the individual porous tubes, these in a unit of any desired Establish height.

Zwischen Roh- und Reingasbereich findet ebenfalls eine feuerfeste elastische Filterbuchse Anwendung, die einen Durchriß des Rohgases in den Reingasraum verhindert und gleichzeitig die Ausdehnungen zwischen den einzelnen Rohren dichtend ausgleicht.There is also a fireproof area between the raw and clean gas areas elastic filter bushing application that allows the raw gas to penetrate into the clean gas space prevents and at the same time seals the expansion between the individual pipes compensates.
