Strahlapparat mit mehreren konzentrischen Düsenkränzen. Patentiert im Deutschen Reiche vom 9. Februar 1910 ab. Jet device with several concentric nozzle rings. Patented in the German Empire on February 9, 1910.

Die Erfindung betrifft einen Strahlapparat mit mehreren konzentrischen Düsenkränzen, welche verschiedene Länge besitzen, und besteht darin, daß die mittleren Düsen die kürzesten und die äußersten die längsten sind, so daß die Mündungen des äußersten Düsenrandes der Mischkammer am nächsten liegen.The invention relates to a jet apparatus with several concentric nozzle rings, which have different lengths, and consists in that the middle nozzles are the shortest and the outermost are the longest, so that the mouths of the outermost nozzle edge closest to the mixing chamber.

Gegenüber bekannten Einrichtungen, bei denen umgekehrt die mittleren Düsen die ίο längsten, die äußeren Düsen dagegen die kürzesten sind, liefert die neue Einrichtung einen besseren Nutzeffekt und erfordert weniger Betriebsenergie, weil kein Hindernis sich dem Eindringen des mitzureißenden Fluidums bis zu den mittleren Düsen entgegensetzt.Compared to known devices in which, conversely, the middle nozzles the ίο the longest, but the outer nozzles are the shortest, the new device delivers better efficiency and requires less operating energy because there is no obstacle to penetration of the fluid to be entrained as far as the middle nozzles.

Da die Mitnahme eines Fluidums durch ein anderes nur durch Reibung geschehen kann, wird das Antriebsfluidum mittels einer größeren Anzahl Düsen a¹, a², a^s hineingesandt, deren Ausgangsöffnungen oder Ausmündungen b auf dem Durchlaßquerschnitt, der zu dem Verteiler^. führt, in geeigneten Abständen liegen, wie dies aus Fig. ι ersichtlich ist. Diese Verteilung ermöglicht, die Fläche der antreibenden Strahlenbündel, auf deren Länge die Reibungswirkung erfolgen soll, so weit, wie für nötig erachtet wird, auszudehnen.Since the entrainment of one fluid by another can only be done by friction, the drive fluid is sent in by means of a larger number of nozzles a ¹ , a ² , a ^s , the outlet openings or orifices b on the passage cross-section leading to the distributor ^. leads, lie at suitable intervals, as can be seen from Fig. ι. This distribution makes it possible to expand the area of the driving beam, along whose length the frictional effect is to take place, as far as is deemed necessary.

Es werden nun die Düsen a¹, a², a³ so angeordnet, daß die Grundrisse ihrer Austrittsöffnungen gleichmäßig auf dem Eintrittsquerschnitt des Verteilers A (Fig. 1) verteilt sind, damit der Flüssigkeitsstrahl, der in den Verteiler eintritt, so gleichmäßig bzw. so homogen wie möglich ist.The nozzles a ¹ , a ² , a ³ are now arranged in such a way that the outlines of their outlet openings are evenly distributed over the inlet cross-section of the distributor A (Fig. 1) so that the jet of liquid that enters the distributor is so evenly distributed. is as homogeneous as possible.

Außerdem werden die Düsen nach konzentrischen Kränzen angeordnet, die der Reihe nach abgestuft sind bzw. stufenförmig liegen, wie dies aus Fig. 2 zu ersehen ist.In addition, the nozzles are arranged according to concentric rings, which are in sequence are stepped or are stepped, as can be seen from FIG.

In dieser Fig. 2 wurde als Beispiel angenommen, daß. 27 gleichgestaltete Düsen zur Verwendung gelangen, die auf drei konzentrische Kränze verteilt sind, und zwar ein Kranz, der aus 3 Düsen a¹, ein Kranz, der aus 9 Düsen a², ein Kranz, der aus 15 Düsen a³ besteht.In this Fig. 2 it was assumed as an example that. 27 identically designed nozzles are used, which are distributed over three concentric rings, namely a ring consisting of 3 nozzles a ¹ , a ring consisting of 9 nozzles a ² , a ring consisting of 15 nozzles a ³ .

Die Austritts Öffnungen bzw. die Ausmündungen der Düsen dieser Kränze liegen in den Ebenen 1-1, 2-2 und 3-3, die in verschiedenen Entfernungen vom Eingang des Verteilers sich befinden. Die Ebene 1-1, welche die Ausmündungen der mittleren Düsen a¹ enthält, ist diejenige, die dem Mischraum A am entferntesten liegt; die Ebene 2-2, welche die Ausmündungen des Kranzes enthält, der aus den zwischenliegenden Düsen α² besteht, liegt dem Mischraum A näher; schließlich ist die Ebene 3-3, in welcher sich die Ausmündungen des Kranzes befinden, der aus den äußeren Düsen a³ gebildetThe outlet openings or the outlets of the nozzles of these rings are in the levels 1-1, 2-2 and 3-3, which are located at different distances from the inlet of the distributor. The plane 1-1, which contains the outlets of the middle nozzles a ¹ , is the one that is furthest away from the mixing space A; the level 2-2, which contains the outlets of the ring, which consists of the intermediate nozzles α ² , is closer to the mixing space A; Finally, the level 3-3 is in which the openings of the ring are located, which is formed from the outer nozzles a ³

Claims

is, the one that is in the closest vicinity of the mixing space A , the outlet of which is in the level 4-4.

That through the driving beams,

'5 which emerge from the three nozzles a ¹ , fluid to be entrained comes into contact with these bundles of rays, this fluid making its way through the spaces between the walls of the other nozzles a ² , a ^s or between those of the Nozzles are present, as is indicated in FIG. 2 by the arrows 5. The cross-section of these intermediate spaces remains constant, and the same cannot be closed due to the spreading of the bundles of rays which emerge from the nozzles of the two subsequent rings a ² , a ^3.

Is the cross-section of these spaces large enough to allow the sucked-in liquid passes through them at a slow speed, it steps with the The bundles of rays emerging from the central nozzle ring in contact, exactly as if these central bundles of rays existed alone.

The distance between levels 1-1 and 2-2 must be such that the bundles of rays in question, when they reach level 2-2, have already taken with them the mass of fluid or amount of liquid that they carry away should; then there is no longer any disadvantage associated with the fact that the bundles of rays emanating from the emerge in the middle of the nozzle ring, form a sheath around this bundle of rays.

In the same way, the fluid that is to be entrained by the bundles of rays which emerge from the nozzles a ^{2 of} the intermediate nozzle ring will come into contact with these bundles of rays after it has only passed through the gaps of constant cross-section, which between the nozzles of the outer rim are present, namely the path followed by the fluid is that which is made recognizable in FIG. 2 by arrows 6. When the drive fluid that emerges from the nozzles of the intermediate ring reaches level 3-3, it has carried away the entire mass of fluid or amount of liquid that it should have carried with it, and there is no longer any disadvantage from the surrounding fluid can no longer get there.

This is finally achieved by the bundles of rays coming from the nozzles of the outer ring emerge, fluid to be entrained in contact with these bundles of rays, and the The path traversed by this fluid is in this case that which is shown in FIG. 2 by the Arrows 7 is illustrated.

As a result of this special device in the mixing chamber, the items to be taken arrive Fluidum just as easily with the bundles of rays of the central nozzle ring as with the bundles of rays of the outer wreath in contact. In this way the possibility is given, not only of the entire friction surface, over the one has to use it appropriately, but it is also in the distribution or diffusion chamber a resulting homogeneous bundle of rays is sent in, which is approximately has one and the same speed in all its points. But this is a basic condition for the distributor gives a good yield.

It has been assumed in Figs. 1 and 2 that 27 nozzles are used which are distributed on three concentric wreaths. But it goes without saying - that these numbers have only been chosen as an example, and that the number of nozzles and wreaths is entirely arbitrary can be.

In Fig. 2, it has been assumed that the nature of the drive film is such is that the application of converging and diverging, i. H. collecting and scattering nozzles is made necessary. However, as can be seen from FIG. 3, the same arrangement also find application when the type of drive fluid is such that the use of simply converging, d. H. collecting nozzles.

The nozzles, which are arranged in steps or tiered, can be used with any blasting equipment Find use, for example, steam ejectors, water injectors, etc., as well as the shape the distributor or diffuser of the apparatus in question may be, so be it that the same converging and diverging, d. h .. collectively and scattering acts like this results, for example, from the beam guide in FIG. 2, or it is that the beam guide is a simply diverging or scattering one, as indicated in FIG. 3.

Godfather τ-An saying:

Jet apparatus with several concentric nozzle rings, which are different Have length, characterized in that the middle nozzles are the shortest and the outermost nozzles are the longest, so that the mouths of the outermost nozzle edge closest to the mixing chamber.
