Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application
"Naßentstauber vorzugsweise für den untertägigen Bergbau mit zweistufiger Schmutzwasserabscheidung" Im untertägigen Bergbau benutzt man vielfach Naßentstauber zum Erfassen und Reinigen der staubbaltigen Grubenwetter."Wet dust extractor preferably for underground mining with two-stage Wastewater separation "In underground mining, wet dust extractors are often used for collecting and cleaning the dusty mine weather.
Diese Naßentstauber bestehen meistens aus einer venturiartigen Agglomerationsstrecke und einem nachgeschalteten drallförmigen Schmutzwasserabscheider, der den Gasstrom vom Benetzungswaser trennen soll.These wet dust extractors usually consist of a venturi-like agglomeration section and a downstream swirl-shaped waste water separator that controls the gas flow should separate from the wetting water.
Die saubere Trennung des Gasstroms vom Benetzungswasser ist stark abhängig vom Druckverlust des Drallabscheiders.The clean separation of the gas flow from the wetting water is strong depending on the pressure loss of the swirl separator.
Um mit geringstem Druckverlust eine gute Trennung zwi schen Rohgas- und Benetzungswasser zu erzielen, wird erfindungsgemäß vorgeschlagen, eine Konstruktion entsprechend beiliegender Zeichnung zu benutzen.In order to achieve a good separation between the raw gas with the lowest pressure loss and to achieve wetting water, the invention proposes a construction to be used in accordance with the enclosed drawing.
In der beiliegenden Zeichnung ist dargestellt: Mit I: das Rohgas, mit 2: di Agglomerationsstrecke, in der das Rohgas mit dem eingedüsten Wasser konfrontiert wird, mit 3: eine radiusförmige Grobtropfenabscheideranordnung, die aus geschlitzten blechförmigen Profilen besteht, über die die Luft durch die Umlenkung der radiusförmigen Ausbildung von den schweren Wassertropfen, die bestrebt sind geradeaus zu fließen, zum größten Teil trennt werden, mit 4: ein Keintropfenabscheider, bestehend aus gewebeförmia angeordneten Tropfenstoßfangern, mit 5: die Li;fter- und Schalldänferanordnun, mit 6: der Wasserkasten, der das Kreislaufwasser beinhaltet, mit 7: ein Hydrozyklon, mit 8: ein Schalimmerventil, das mit Frischwasser in Verbindung steht und bei Bedarf automatisch den Wasserlcasten (6) füllt, mit 9: die Pumpenanordnung, die aus dem Wasserkasten (6) das Wasser in die Agglomerationsstrecke (2) hineinsprühen und zum anderen aus dem Bereich des Grobtropfenabscheiders (3) und Feintropfenabscheiders (4) das Wasser über den Hydrozyklon (7) drücken; im Mittelzyklon wird das Wasser vom agglomerierten Staubrückstand gereinigt und fließt dem Wasserkasten (6) zu, mit lO: der Grundrahmen, auf dem die gesamte Gasreinigungseinrichtung aufgebaut ist.The attached drawing shows: With I: the raw gas, with 2: di agglomeration section in which the raw gas confronts the injected water will, with 3: a radius-shaped coarse droplet separator arrangement, which consists of slotted sheet-metal profiles through which the air flows through the Redirection of the radius-shaped formation of the heavy water droplets, which strives are to flow straight ahead, for the most part are to be separated, with 4: a no-droplet separator, consisting of fabric-shaped drop bumpers, with 5: the Li; fter- and Schalldänferanordnun, with 6: the water tank, which contains the circulating water, with 7: a hydrocyclone, with 8: a sound valve that connects with fresh water stands and, if necessary, automatically fills the water tank (6), with 9: the pump arrangement, which spray the water from the water tank (6) into the agglomeration section (2) and on the other hand from the area of the coarse droplet separator (3) and fine droplet separator (4) push the water over the hydrocyclone (7); in the central cyclone the water cleaned of agglomerated dust residue and flows to the water tank (6), with 10: the base frame on which the entire gas cleaning device is built is.
Seibstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abanderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Naßentstaubung für den Untertage-Bergbau so zu bauen, daß hinter der Agglomerationsstrecke vor dem Lüfter die Trennung zwischen Gasstrom und Wassertropfen zweistufig vorgenommen wird, und zwar erfindungsgemäß über einen Grobtropfenabscheider, der als hogenformiger Spaltflachen-Separator ausgebildet ist, über dem die Luft durch umgelenkte Zwangsführung das Wasser aufprallen und durch die Spalten nach unten in den Pumpensumpf zur Pumpe ableiten.It goes without saying that the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Modifications possible without deviating from the basic idea, a wet dedusting to build for underground mining so that behind the agglomeration stretch in front the fan made the separation between gas flow and water droplets in two stages is, according to the invention via a coarse droplet separator, which is as a hogenformiger Gap separator is formed over which the air is deflected by forced guidance bounce the water and through the crevices down into the pump sump to the pump derive.
Das Gas fließt zum Feintropfenabscheider und agglomeriert hier mit dem Restwassergehalt zu weiteren Tropfenbildungen, die dann entsprechend ihrer Schwerkraft ebenfalls zum Pumpensumpf abtropfen und den Pumpenanordnungen (9) zufließen.The gas flows to the fine droplet separator and agglomerates with it the residual water content to further drop formations, which then according to their gravity also drain to the pump sump and flow to the pump assemblies (9).
Die Lüfter sind erfindungsgema'.ß so angeordnet, daß sie oberhalb vom Wasserkasten aufgelagert sind.According to the invention, the fans are arranged in such a way that they are above are supported by the water tank.
