Abstract

Zyklonabscheider mit einem im oberen Abschnitt zylindrischen Zyklongehäuse (1) mit in einer Radialebene desselben angeordneter ebener Deckelplatte (2), unter welcher am oberen Ende des Zyklongehäuses (1) entlang eines in diesem ausgebildeten Umfangsspaltes (3) ein Einlaufkanal (4) mündet, der sich mit seiner dem Zyklongehäuse (1) abgewandten Außenwand (5) entlang eines Spiralbogens erstreckt, an dessen radial äußerem Ende der Einlaufkanal (4) mit seiner radial inneren Wand (8) in die Wand des Zyklongehäuses (1) tangential übergeht und an dessen radial innerem Ende der Einlaufkanal (4) mit seiner Außenwand (5) tangential in die Wand des Zyklongehäuses (1) übergeht. Um die Einlaufbedingungen des staubbeladenen Gasstromes unter Vermeidung von Totwassergebieten und Druckverlusten günstig zu gestalten, steht der Einlaufkanal (4) mit seiner oberen Wand (9) am radial äußeren Ende (6) des Spiralbogens über die Deckelplatte (2) axial nach oben hinaus und verläuft entlang des Spiralbogens geneigt und läuft an dem radial inneren Ende (7) des Spiralbogens stufenfrei in die Deckelplatte (2) ein, wobei die untere Begrenzungskante (10) des Umfangsspaltes (3) parallel zur oberen Wand (9) des Einlaufkanals (4) geneigt verläuft. Cyclone separator with a cylindrical one in the upper section Cyclone housing (1) with the same in a radial plane arranged flat cover plate (2), under which on the top End of the cyclone housing (1) along one in this formed circumferential gap (3) opens an inlet channel (4), which faces away from the cyclone housing (1) Outer wall (5) extends along a spiral arch, on the radially outer end of the inlet channel (4) with its radial inner wall (8) into the wall of the cyclone housing (1) passes tangentially and at the radially inner end of the Inlet channel (4) with its outer wall (5) tangentially into the Wall of the cyclone housing (1) merges. To the Inlet conditions of the dust-laden gas flow under Avoidance of dead water areas and pressure losses cheap to design, the inlet channel (4) stands with its upper Wall (9) at the radially outer end (6) of the spiral arch over the Cover plate (2) axially upwards and runs along of the spiral arc is inclined and runs at the radially inner end (7) of the spiral arch step-free into the cover plate (2), the lower boundary edge (10) of the peripheral gap (3) inclined parallel to the upper wall (9) of the inlet channel (4) runs.
