Abstract

A filter for purifying gases contg. sticky or baking-on substances has a filter material which is resistant to high temp. and can be kept in a "breathing" condition by thermal treatment, pref. by flame action. Typically, for a coke-oven plant where gases at 150-250 degrees C. contain tar and similar products, a filter fabric is used, composed of a refractory, ceramic fabric, over which a hot gas flame is conducted at regular intervals to burn off the deposits.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Filter mit thermischer Reinigung' In der Gasreinigungstechnik treten vielfach Belastungen im Rohgas auf, die ein Zukleben des Filtermaterials bewirken.'Filters with thermal cleaning' Step into gas cleaning technology multiple loads in the raw gas that cause the filter material to stick.

Dieses Zukleben läßt sich mit den bekannten Technologien wie Wasserstrahlreinigung bzw. Druckschock- oder Rättelreinigung nicht beseitigen.This can be done with the well-known technologies such as water jet cleaning or do not eliminate pressure shock or riddle cleaning.

Um Gase, die mit klebenden und/oder backenden Verunreinigungen belastet sind, zu reinigen, wird erfindungsgemäß vorgeschlagen, Filterstoffe zu verwenden, die 1. hochtemperaturbeständig sind und 2. durch thermische Beaufschlagung die backenden und/oder klebenden Massen ausbrennen und das Filter weiterhin aktiv halten.About gases that are contaminated with sticky and / or baking contaminants are to be cleaned, it is proposed according to the invention to use filter materials, The 1. are high temperature resistant and 2. the baking ends due to thermal exposure and / or burn out adhesive masses and keep the filter active.

Hierzu können beispielsweise vergütete, keramische Filter materialien Anwendung finden, die kontinuierlich oder diskontinuierlich durch Flammdüsen oder durch heiße Gase beaufschlagt werden.For this purpose, tempered, ceramic filter materials can be used, for example Find application that is continuous or discontinuous by flame nozzles or exposed to hot gases.

So ist es zum Beispiel möglich, in Kokereianlagen Gase, die mit etwa 150 - 2500 Temperatur teer- und phenolhaltige Verunreinigungen mitschleppen, durch ein Filtergewebe zu reinigen, das aus einem hochtemperaturfesten, vergüteten Keramikgewebe besteht, das durch Heißgasbeflammung, die kontinuierlich in Form einer Blasdüse an dem Filtermaterial im notwendigen Zeitintervall vorbeigeführt wird, den Schadstoff abflammt und somit die Atmungsaktivität des Filtermaterials erhalten bleibt.For example, in coking plants it is possible to use gases with about 150 - 2500 temperature dragging tar and phenol-containing impurities through to clean a filter fabric made of a high temperature resistant, tempered ceramic fabric consists, that by hot gas flame, which continuously in the form of a blowing nozzle The pollutant is passed by the filter material in the necessary time interval flames and thus the breathability of the filter material is retained.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, ein Filtermaterial, das mit 1 bezeichnet ist, durch einen Gasstrom 2, der mit klebenden Schadstoffen belastet ist, zu beaufschlagen und durch eine kontinuierlich oder diskontinuierlich arbeitende Düseneinrichtung 3 mit entsprechend hohen Temperaturen zu beaufschlagen, um dadurch die Inaktivität des Filters aufzuheben und die filternden Eigenschaften über entsprechend wirtschaftlich vertretbare Zeiträume aktiviert zu halten.Of course, the invention is not limited to the above in detail The forms of training described are limited, but there are numerous changes possible, but without deviating from the basic idea, a filter material that is denoted by 1, through a gas stream 2, which is loaded with adhesive pollutants is to be applied and by a continuously or discontinuously working To apply nozzle device 3 with correspondingly high temperatures in order to thereby to cancel the inactivity of the filter and change the filtering properties accordingly to keep economically justifiable periods activated.
