Description

Verfahren und Vorrichtung zum Entstauben der Abgase bei Trocknern. Bei Ausübung des Verfahrens nach Patent 413766 hat sich in der Praxis ergeben, daß bei der Trocknung von größtenteils feinkörnigem Gut (z. B. mulmige ungesiebte Braunkohle) an der äußeren feststehenden Trommel die Durchtrittsöffnungen für die zu entstaubenden Abgase sich leicht verstopfen, da die Drehung der inneren Filterwandung ein Anpressen des feinkörnigen Gutes an die äußere feststehende Filterwan- Jung bewirkt. Hierdurch wird natürlich die Leistungusfahigkeit der Anlage erheblich herabgesetzt, da durch den- .vergrößerten Widerstand der Sauger nur eine beschränkte Menge Abgase durchzusaugen vermag.Method and device for dedusting exhaust gases from dryers. When exercising the method according to patent 413766 it has been found in practice that when drying mostly fine-grained material (e.g. queasy unscreened brown coal) the passage openings for the dust to be dedusted on the outer stationary drum Exhaust gases become clogged easily because the rotation of the inner filter wall presses against it the fine-grained material to the outer fixed filter wall young causes. This of course significantly reduces the performance of the system, because of the increased resistance of the vacuum cleaner only a limited amount of exhaust gases able to suck through.

Gemäß der Erfindung soll nun eine Verstopfung der Durchtrittsöffnung für die Abgase, selbst bei Trocknung v*-on nur ganz feinkörnigem und äußerst nassem Gut, dadurch vermieden werden, daß durch gleichzeitige langsame Drehung beider Filterwandlungen oder durch Drehung des Bodenbleches die Filtermasse an den Wandlungen beständig erneuert wird.According to the invention, a blockage of the passage opening is now intended for the exhaust gases, even with drying of only very fine-grained and extremely wet Good, can be avoided by simultaneous slow rotation of both filter conversions or by rotating the bottom plate, the filter mass is constantly at the transformations is renewed.

In der Zeichnung ist eine zur Ausführung des Verfahrens dienende Vorrichtung veranschaulicht.In the drawing is a device used to carry out the method illustrated.

Oberhalb des Trockenraums sind über einem ringförmigen Bodenblech I die beiden gleichachsigen luftdurchlässigen TrommelnA und B an Armen D durch die senkrechte Welle C drehbar eingebaut. Über der zwi-. schen den Trommeln befindlichen Filterschicht ist in der Decke K eine ZubrIngöffnung mit anschließendem Behälter H für die Einbringung des zu trocknenden Gutes angebracht. Ein über dem festen Boden I sich bewegendes Kratzerblech E, das mit den Trommeln fest verbunden ist, streicht eine genau regelbare Menge des zu trocknenden Gutes von dem Bodenblech I ab. Nach oben hin gegen die Decke K ist der äußere Mantel A zweckmäßig durch eine Sandtasse M abgeschlossen. Die gleiche Wirkung wird erzielt, wenn der äußere Mantel A unabhängig vom inneren Mantel B gelagert wird und die beiden Trommeln in entgegengesetzter Richtung sich bewegen. Weitere Versuche haben ergeben, daß eine Verstopfung der Luftdurchtrittsöffnungen auch dann mit Sicherheit vermieden wird, wenn sowohl der äußere als auch der innere Mantel feststehend eingebaut wird und das untere Bodenblech I eine drehende Bewegung erhält. In diesem Falle würde das Kratzerblech E in fester Verbindung mit dem Bodenblech stehen. Außerdem würde bei dieser letzteren Anordnung der Speisebehälter H sich über den ganzen Ringraum erstrecken müssen.Above the drying room, the two equiaxed air-permeable drums A and B are rotatably installed on arms D by means of the vertical shaft C via an annular bottom plate I. About the between. Between the drums located filter layer, a feed opening with a subsequent container H for the introduction of the goods to be dried is attached in the ceiling K. A scraper plate E moving over the solid floor I, which is firmly connected to the drums, sweeps a precisely controllable amount of the material to be dried from the floor plate I. The outer jacket A is expediently closed off by a sand cup M towards the top against the ceiling K. The same effect is achieved if the outer shell A is stored independently of the inner shell B and the two drums move in opposite directions. Further tests have shown that clogging of the air passage openings is also avoided with certainty if both the outer and the inner jacket are installed in a fixed manner and the lower floor panel I is given a rotating movement. In this case, the scraper plate E would be firmly connected to the floor pan. In addition, with this latter arrangement, the feed container H would have to extend over the entire annulus.
