Description
Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application
"Filter zur Reinigung von Abgasen mit Schutzschild für Fremdkörper" Es ist bekannt, Abgase, die staub- und gasförmige Schadstoffe mitführen, mittels Trockenfilter zu reinigen."Filter for cleaning exhaust gases with a protective shield for foreign bodies" It is known to use exhaust gases that carry dust and gaseous pollutants Clean dry filter.
Bei der Gasreinigung von insbesondere Mullverbrennungsanlagen werden vielfach teerhaltige oder auch kunststoffartige, noch nicht gänzlich verbrannte Rückstände verpuffungsförmig aufgewirbelt und benachteiligen die filternden Elemente durch Aufkleben, Ansintern, Zubacken oder mit ähnlichen nicht erwünschten Benachteiligungen.In the gas cleaning of waste incineration plants in particular often tar-containing or plastic-like, not yet completely burned Residues are whirled up in the form of a detonation and put the filtering elements at a disadvantage by sticking, sintering, baking or with similar undesirable disadvantages.
Um diese Benachteiligungen der Filterflächen zu vermeiden, wird erfindungsgemäß vorgeschlagen, der eigentlichen Filterfläche ein leicht auswechselbares gutatmungsaktives, nicht zu hohen Druckverlust erzeugendes Schutzschild vorzulagern, das in der Lage ist, die die Filterelemente benachteiligenden Schadstoffe fernzuhalten.In order to avoid these disadvantages of the filter surfaces, according to the invention suggested that the actual filter surface be an easily exchangeable, easy-to-breathe, upstream of a protective shield that is not capable of causing excessive pressure loss is to keep away the pollutants that put the filter elements at a disadvantage.
In der beiliegenden Skizze ist der erfindungsgemäße Gegenstand dargestellt: mit 1 z. B. ein für die Staubabscheidung vorgesehener Filter, mit 2 das Rohgas, mit 3 das Reingas, mit 4 die filternden Elemente, z. B. Heißgas-Filterelemente, mit 5 die erfindungsgemäße Schutzschildanordnung, die aus Gittern besteht, vorzugsweise drahtförmig, zwischen denen geblähte, stark feuchtigkeitsaufnehmende, hochtemperaturfeste Perlite eingelagert ist, die selbstglühende Kunststoffteile oder auch Metalloxide sowie klebefreudige Massen aufnimmt, ohne dabei z. B. einen Druckverlust von mehr als 5 - 10 mm WS zu erzeugen, und in einfachster Weise bei erhöhtem Druckanstieg durch Zukleben und/oder Aussintern leicht abgelassen und neu nachgefüllt werden kann.The subject according to the invention is shown in the attached sketch: with 1 z. B. a filter provided for dust separation, with 2 the raw gas, with 3 the clean gas, with 4 the filtering elements, e.g. B. hot gas filter elements, with 5 the protective shield arrangement according to the invention, which consists of grids, preferably wire-shaped, between which billowing, highly moisture-absorbing, high-temperature-resistant Perlite is embedded, the self-glowing plastic parts or metal oxides as well as sticky masses without doing z. B. a pressure loss of more as 5 - 10 mm WS, and in the simplest way with increased pressure increase can be easily drained and refilled by sealing and / or sintering out can.
Dieses kann z. B. während des Filterbetriebes bei 6 nachgefüllt werden und bei 7 kontinuierlich oder diskontinuierlich abgelassen werden.This can e.g. B. be refilled at 6 during the filter operation and at 7 are discharged continuously or intermittently.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsnormen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Gasreinigungsfilter mit einer vorgesetzten Schutzschildanordnung zu versehen, wobei das Schutzschild aus wabenartigen Profilen besteht, vorzugsweise Draht, zwischen denen geblähte Perlite mit hoher Temperaturbeständigkeit, z. B. über 1200 OC, eingelagert ist, die kontinuierlich oder diskontinuierlich zu- und abgeführt werden kann.Of course, the invention is not limited to the above in detail The training standards described are limited, but there are numerous changes possible, but without deviating from the basic idea, a gas cleaning filter to be provided with an upstream protective shield arrangement, the protective shield consists of honeycomb-like profiles, preferably wire, between which expanded perlite with high temperature resistance, e.g. B. over 1200 OC, is stored continuously or can be supplied and discharged discontinuously.
