Gebrauchsmusteranmeldung "Drallschaufelkranz für Entstaubungszyklon"Utility model registration "swirl vane ring for dedusting cyclone"
Die Neuerung bezieht sieh auf EntstaubungsZyklone mit oberer axialer Gaseintritteöffnung in der ein Drallschaufe!kranz dem antretenden Grasstrom eine Drallbewegung erteilt.The innovation refers to the dedusting cyclones with upper axial Gas inlet opening in which a swirl vane wreath to the approaching one Grass flow given a twisting motion.
Solche Zyklone bestehen jeweils aus einem äußeren Abscheiderohr und einem koaxialen inneren Reingasrohr, aus dem das gereinigte Gas entgegen der G-aseintrittsrichtung nach oben wieder ausströmt. Das äußere Abscheiderohr ist in seinem unteren Teil konisch-verjüngt und hat nach unten hin eine Staubaus tragsöffnung.. Such cyclones each consist of an outer separation pipe and a coaxial inner clean gas pipe, from which the cleaned gas Gas flows out upwards against the gas inlet direction. The lower part of the outer separator tube is conically tapered and has a dust discharge opening at the bottom.
Die Bezeichnungen oben und unten sind im allgemeinen relativ zu den Zyklonenden zu verstehen, um damit auch zu berücksichtigen, daß es seit langem bekannt ist (gemäß DEP 39219 v. 25» 7. 1886) den Zyklon in jeder beliebigen räumlichen Lage anzuordnen.The terms above and below are generally relative to to understand the cyclone end in order to take into account that it has been known for a long time (according to DEP 39219 v. 25 »7. 1886) to arrange the cyclone in any spatial position.
Die Feuerung betrifft insbesondere die konstruktive Ausgestaltung des Drallschaufelkranzes. Dieser ist üblicherweise mit einem oder mehreren Flügeln versehen, die den Gasstrom aus der gradeη axialen Richtung in eine schraubenförmige Drallbewegung umlenken. Die Hügel werden deshalb üblicherweise als Wendelflächen ausgebildet.The firing relates in particular to the structural design of the swirl blade ring. This is usually with an or provided several blades, which the gas flow from the gradeη axial Divert direction into a helical twisting movement. The hills are therefore usually designed as helical surfaces.
Ton dieser bekannten formgebung weicht der mustergemäße Drallschaufelkranz ab, in dem die Flügel nach außen hängend gestaltet sind. Die inneren und äußeren Begrenzungskanten der Flügelflächen sind zwar auch Schraubenlinien, jedoch hat die äußere mustergemäß eine größere Steigung als die innere.The pattern of the swirl vane ring gives way to this well-known shape in which the wings are designed to hang outwards. The inner and outer boundary edges of the wing surfaces are also helical lines, but the outer one has a pattern according to the pattern greater slope than the inner one.
Durch das Abfallen der Flügelflächen nach außen hin, wird der Drall-, bewegung eine radiale Komponente überlagert, durch die den Staubteilchen zusätzlich zur Fliehkraft eine Beschleunigung nach der äußeren Zyklonwand hin erteilt wird. Versuche haben gezeigt, daß durch eine solche Gestaltung der Flügelflächen der Entstaubungsgrad eines Zyklonentstaubers-erhöht wird und daß außerdem weniger Spritzkorn ins Reingas gelangt/ Bas Spritzkorn besteht aus groben Staubpartikeln, z. B. aus entgasten Kohlenpartikeln, die von den Flügelflächen und den Zyklonwandungen abprallen und dabei in.den Reingasaustritt geraten. Diese Teilchen erhalten offensichtlich auf den nach außen hängenden Flügelflächen eine Bewegungskomponente nach der Zyklonwand zu·As the wing surfaces drop outwards, the swirl, movement superimposed a radial component through which the dust particles in addition to the centrifugal force, an acceleration towards the outer cyclone wall is issued. Tests have shown that By designing the wing surfaces in this way, the degree of dust removal of a cyclone dust extractor is increased and, moreover, less Spray grain gets into the clean gas / Bas spray grain consists of coarse Dust particles, e.g. B. from degassed carbon particles that bounce off the wing surfaces and the cyclone walls and thereby in.den Clean gas leakage advised. These particles get obviously a component of movement on the wing surfaces hanging outwards after the cyclone wall to
Mustergemäß hat der Drall se häuf el-kranz an seinen oberen Flügelenden mindestens 3 Nasen, die über die äuBeren Mantellinien, vorstehen und der Unterstützung des Drallsehaufelkranze-s- -auf dem oberen Zyklonende dienen. "^_^ According to the pattern, the twist often has an el-wreath on its upper wing tips at least 3 lugs that protrude above the outer surface lines and the Support the swirl blade ring on the upper end of the cyclone.
