Description

Vorrichtung zum Mischen von Gas mit staub- oder pulverförmigen Stoffen.Device for mixing gas with dusty or powdery substances.

Zum Mischen von Gas mit staub- oder pulverförmigen Stoffen, z. B. Kohlenstaub, für Kohlenstaubfeuerungen sind bereits Düsen mit Schraubleng, angen vorgeschlagen worden, durch welche die staub- oder pulverförmigen Teilchen in drehende Bewegung versetzt werden, bevor sie die Verwendungsstelle erreichen. For mixing gas with dusty or powdery substances, e.g. B. Coal dust, nozzles with screw lengths are already attached for coal dust firing has been proposed by which the dusty or powdery particles in rotating Movement are moved before they reach the point of use.

Die Folge dieser Drehbewegung der festen Teilchen ist die Bildung eines Ringes um den Gasstrom herum, wodurch die angestrebte Mischung verhindert wird. Dabei werden die schwereren Teilchen weiter als die leichteren nach außen geschleudert, so daß in die Verbrennungskammer nicht das gewünschte homogene Gemisch einströmt. Sobald der Strom die Verbrennungskammer erreicht, findet eine weitere Entmischung statt, da die schwereren Teilchen nunmehr unbehindert durch die Fliehkraft nach außen geschleudert werden.The result of this rotational movement of the solid particles is formation a ring around the gas flow, preventing the desired mixing will. The heavier particles are farther outwards than the lighter ones thrown so that in the combustion chamber not the desired homogeneous mixture flows in. As soon as the stream reaches the combustion chamber, another takes place Segregation takes place because the heavier particles are now unhindered by the centrifugal force be thrown outwards.

Der Zweck der Erfindung ist nun, eine Vorrichtung zu schaffen, durch welche eine unbedingt einwandfreie Mischung des Isohlenstaubes 0. dgl. mit Gas gewährleistet und der Verbrennungskammer ein homogenes Gemisch zugeführt wird, selbst wenn dies nach der Mischung durch Abzweigkanäle geleitet wird, also einen Richtungswechsel erfährt. The purpose of the invention is now to create a device through which ensures an absolutely flawless mixture of the Isohlenstaubes 0. Like. With gas and a homogeneous mixture is supplied to the combustion chamber even if so is passed through branch channels after mixing, i.e. a change of direction learns.

-Um dies zu erreichens ist erfindungsgernaß hinter dem oder den im Zuleitungsrohr angeordneten, schraubenförmig gebogenen Blechstreifen ein Gitter oder Netz mit runden oder eckigen Durchbrechungen angebracht. -To achieve this, there is inventiveness behind the im Supply pipe arranged, helically bent sheet metal strips a grid or a net with round or square openings.

Der durch die gebogenen Blechstreifen innerhalb des Zuleitungsrohres in drehende Bewegung versetzte pulver- oder staubförmige Stoff mischt sich mit dem durchströmenden Gas, und dieses Gemisch wird dann durch ein vor den Abzaveigstellen bzw. vor der Rohrmündung liegendes, zweckmäßig aus dünnen Blechlamellen bestehendes Gitter oder Netz mit runden oder eckigen Durchbrechungen in dünne Strahlen zerlegt, die der Verwendungssteile zugeführt werden können, ohne daß eine Entmischung zu befürchten ist. The one through the bent sheet metal strips inside the supply pipe Powder or dusty substance set in rotating motion mixes with the flowing through gas, and this mixture is then passed through a front of the Abzaveigstellen or in front of the pipe mouth, suitably consisting of thin sheet metal lamellas Grid or net with round or square openings broken down into thin beams, which can be supplied to the parts of use without segregation is feared.
