To this end, at least one conditioning gas flow (2) is supplied to the process region, said flow consisting of at least one primary gas flow (3) and at least one secondary gas flow (4).

Description

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Konditionieren wenigstens eines Prozessbereichs.The invention relates to a method and a device for conditioning at least one process area.

Bei Webmaschinen sind zum Reinigen oder Entstauben von Maschinenzonen, insbesondere den zugeführten Webketten, Konditioniersysteme bekannt, die über eine schlitzförmige Austrittsöffnung einen gerichteten Luftstrahl mit relativ hoher Strömungsgeschwindigkeit auf den zu konditionierenden Prozessbereich richten und die Maschinenzonen, insbesondere die Webketten, durch Abblasen entstauben. Der schlitzförmige Austritt erstreckt sich quer zur Webkette über deren volle Breite und entlässt einen gegen die Webkette gerichteten Strahl konditionierte Luft. Die Konditioniergröße ist bei diesen Konditioniersystemen die Staubfreiheit oder Reinheit und ggf. auch die Luftfeuchte des Prozessbereiches, insbesondere der Webketten. Diese Systeme haben den Vorteil einer stabilen Luftströmung, einer Reinigung der beblasenen Prozessbereiche sowie eine hohe Eindringtiefe oder Strahllänge. Einen gewissen Nachteil stellt die relativ hohe Induktion durch Mitführen und Vermischen mit Umgebungsluft, die im Allgemeinen nicht oder weniger konditioniert ist, dar, die die Konditionierleistung vermindert, insbesondere den Staubeintrag in die konditionierte Luft durch induktionsbedingte Ansaugung von Staub aus der Umgebungsluft erhöht. Solche Systeme sind beispielsweise in EP 0 558 718 B1 als Stand der Technik beschrieben.In weaving machines for cleaning or dedusting of machine zones, in particular the supplied warps, conditioning systems are known which direct a directed air jet with relatively high flow rate to the process area to be conditioned via a slot-shaped outlet opening and dedust the machine zones, in particular the warps, by blowing off. The slot-shaped outlet extends transversely to the warp over its full width and emits a directed against the warp beam conditioned air. The conditioning size in these conditioning systems is the absence of dust or purity and possibly also the air humidity of the process area, in particular the warp threads. These systems have the advantage of a stable air flow, a cleaning of the blown process areas as well as a high penetration depth or jet length. A certain disadvantage is the relatively high induction by entrainment and mixing with ambient air, which is generally not or less conditioned, which reduces the conditioning performance, in particular increases the dust input to the conditioned air by induction-induced intake of dust from the ambient air. Such systems are for example in EP 0 558 718 B1 described as prior art.

Aus EP 0 558 718 B1 sind ferner ein Verfahren und eine Vorrichtung zur Klimatisierung von Webmaschinen bekannt, bei denen das Klima lokal unmittelbar an der Webmaschine beeinflusst wird, also ein Raumbereich an der Webmaschine konditioniert wird. Hierzu wird eine als "kolbenartige Verdrängungsströmung" bezeichnete Strömung mit über ihren vollen Querschnitt annähernd einheitlicher Verteilung und einer annähernd gleichen Geschwindigkeit verstanden. Es werden Austrittsgeschwindigkeiten zwischen 0,3 und 1,2 m/s für den Luftstrom eingestellt. Die Klimaluft wird bei diesem bekannten System zum Befeuchten der Webkette der Webmaschine eingesetzt. Konditioniergröße ist also der Feuchtegehalt der Luft. Aufgrund der geringen Geschwindigkeit der Verdrängungsströmung wird im Vergleich zu einem aus einer schlitzförmigen Austrittsöffnung ausgeblasenen Luftstrahl mit hoher Strömungsgeschwindigkeit eine höhere Effizienz bei der Abgabe der Feuchtigkeit von der Luft auf die Kettfäden erreicht. Außerdem ist die Induktion von Umgebungsluft vergleichsweise gering. Damit wird durch die Umgebungsluft die Konditionierluft sowohl in ihrem Feuchtegehalt als auch hinsichtlich ihrer Staubfreiheit wenig beeinflusst. Nachteile bei diesem aus EP 0 558 798 B1 bekannten Konditioniersystem sind jedoch zum einen eine vergleichsweise instabile Luftströmung, die durch im Raum auftretende Querströmungen negativ beeinflusst werden kann, sowie das Fehlen einer Reinigungswirkung von Maschinenzonen und auch das Fehlen einer Lenkungsmöglichkeit der Klimaluftströmung.Out EP 0 558 718 B1 Furthermore, a method and a device for conditioning of looms are known in which the climate is locally influenced directly on the loom, so a space area is conditioned on the weaving machine. For this purpose, a flow referred to as a "piston-like displacement flow" is understood to mean approximately uniform distribution over its full cross section and an approximately equal speed. Outlet speeds between 0.3 and 1.2 m / s are set for the air flow. The climate air is at this known system used for wetting the warp of the loom. Conditioner size is therefore the moisture content of the air. Due to the low velocity of the displacement flow, a higher efficiency in the discharge of moisture from the air to the warp yarns is achieved as compared to a high velocity stream of air bled out of a slit shaped orifice. In addition, the induction of ambient air is comparatively low. Thus, the conditioning air is influenced by the ambient air, the conditioning air, both in their moisture content and in terms of their dust-free. Disadvantages of this EP 0 558 798 B1 However, known conditioning system are on the one hand a relatively unstable air flow, which can be negatively influenced by occurring in the space cross flows, and the lack of a cleaning effect of machine zones and also the lack of guidance of the climatic air flow.

Aus der DE43 09 416 A1 ist ein weiteres Verfahren und eine Vorrichtung bekannt die es ermöglicht eine Prozessregion gezielt zu Klimatisieren. So können mit den Vorrichtungen unterschiedliche Luftzustände in bestimmten Abständen vom Luftauslaß, individuell einstellbar, hergestellt werden.From the DE43 09 416 A1 Another method and a device is known which allows a process region to be specifically air-conditioned. Thus, with the devices different air conditions at certain intervals from the air outlet, individually adjustable, can be produced.

Zudem kann die Raum- und Prozessluft mit einem Klimasystem geregelt werden.In addition, the room and process air can be controlled with a climate system.

Aber auch bei dieser Vorrichtung ist es nicht zu vermeiden, dass im Raum auftretende Querströmungen sich negativen auf den Prozessbereich auswirken. So kann nicht sichergestellt werden, dass der Prozessbereich richtig konditioniert wird.But even with this device, it is unavoidable that transverse flows occurring in the room have a negative effect on the process area. This does not ensure that the process area is properly conditioned.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Konditionieren eines Prozesse in wenigstens einem Prozessbereich anzugeben, bei denen die genannten Nachteile beim Stand der Technik wenigstens teilweise vermindert oder ganz vermieden werden.The invention is based on the object of specifying a method and a device for conditioning a process in at least one process area, in which the disadvantages mentioned in the prior art are at least partially reduced or completely avoided.

Diese Aufgabe wird hinsichtlich des Verfahrens gelöst mit den Merkmalen des Anspruchs 1 und hinsichtlich der Vorrichtung gelöst mit den Merkmalen des Anspruchs 32.This object is achieved with regard to the method with the features of claim 1 and with respect to the device solved with the features of claim 32nd

Das Verfahren gemäß Anspruch 1 ist zum Konditionieren wenigstens eines Prozessbereichs oder eines Prozesses in wenigstens einem Prozessbereich geeignet und bestimmt und umfasst die folgenden Verfahrensschritte:

  1. a) Erzeugen wenigstens eines Konditioniergasstromes, der
    • a1) wenigstens einen Primärgasstrom und
    • a2) wenigstens einen Sekundätgasstrom umfasst,
    • a3) wobei der Sekundärgasstrom den Primärgasstrom im Wesentlichen vollständig umschließt oder umgibt und
    • a4) der Primärgasstrom eine wenigstens im Mittel höhere Strömungsgeschwindigkeit aufweist als der Sekundärgasstrom,
  2. b) Zuführen dieses wenigstens einen Konditioniergasstromes zu dem oder jedem Prozessbereich,
The method according to claim 1 is suitable and intended for conditioning at least one process area or a process in at least one process area and comprises the following method steps:
  1. a) generating at least one conditioning gas stream, the
    • a1) at least one primary gas stream and
    • a2) comprises at least one secondary gas stream,
    • a3) wherein the secondary gas flow substantially completely surrounds or surrounds the primary gas flow and
    • a4) the primary gas flow has an at least on average higher flow velocity than the secondary gas flow,
  2. b) supplying this at least one conditioning gas stream to the or each process area,

Die Vorrichtung gemäß Anspruch 12 ist zum Konditionieren wenigstens eines Prozessbereichs oder eines Prozesses in wenigstens einem Prozessbereich und/oder zum Durchführen eines Verfahrens gemäß der Erfindung geeignet und bestimmt und umfasst Mittel zum Erzeugen wenigstens eines Konditioniergasstromes, der dem oder jeden Prozessbereich zuführbar oder zugeführt ist, wobei wenigstens ein Konditioniergasstrom wenigstens einen Primärgasstrom und wenigstens einen Sekundärgasstrom umfasst, wobei der Sekundärgasstrom den Primärgasstrom im Wesentlichen vollständig umschließt und der Primärgasstrom eine wenigstens im Mittel höhere Strömungsgeschwindigkeit aufweist als der Sekundärgasstrom.The apparatus according to claim 12 is suitable for conditioning at least one process area or process in at least one process area and / or performing a method according to the invention and comprises means for generating at least one conditioning gas stream to be fed to the or each process area; wherein at least one conditioning gas stream comprises at least one primary gas stream and at least one secondary gas stream, the secondary gas stream substantially completely enclosing the primary gas stream and the primary gas stream having at least a higher average flow rate than the secondary gas stream.

Die Erfindung beruht auf der Überlegung, einen Primärgasstrom mit vergleichsweise hoher Strömungsgeschwindigkeit in einen Sekundärgasstrom mit einer niedrigeren Strömungsgeschwindigkeit einzubetten oder einzuschließen. Der Sekundärgasstrom umgibt also den Primärgasstrom an einer die Stromlinien oder Strömungsrichtung des Primärgasstromes umschließenden Umfangsfläche oder Außenfläche, so dass von dort keine Umgebungsluft unmittelbar in den Primärgasstrom gelangen kann. Die Induktion von Umgebungsluft in den schnell strömenden Primärgasstrom und damit eine Verfälschung der Konditionierung des Primärgasstromes durch die Umgebungsluft wird somit reduziert oder sogar ganz verhindert. Der Primärgasstrom mit der hohen Strömungsgeschwindigkeit führt zudem den Sekundärgasstrom mit sich mit und richtet diesen gemäß der Strömungsführung des Primärgasstromes mit aus. Somit wird also ein Konditioniergasstrom erzeugt, der durchaus eine vergleichbare Richtcharakteristik wie ein bekannter Luftstrahl gemäß dem eingangs genannten Stand der Technik hat, andererseits jedoch unempfindlicher gegenüber einer negativen Beeinflussung der Konditionierung durch Induktion von Umgebungsluft ist als ein Luftstrahl beim Stand der Technik.The invention is based on the idea of embedding or enclosing a stream of primary gas at a comparatively high flow rate in a secondary flow of gas at a lower flow rate. The secondary gas flow thus surrounds the primary gas flow at a peripheral surface or outer surface enclosing the flow lines or flow direction of the primary gas flow, so that ambient air can not enter the primary gas flow directly from there. The induction of ambient air in the rapidly flowing primary gas flow and thus a distortion of the conditioning of the primary gas flow through the ambient air is thus reduced or even completely prevented. The primary gas stream with the high flow velocity also carries with it the secondary gas flow and aligns with it in accordance with the flow guidance of the primary gas stream. Thus, therefore, a conditioning gas flow is generated, which has quite a comparable directional characteristic as a known air jet according to the aforementioned prior art, but on the other hand, less sensitive to a negative effect on the conditioning by induction of ambient air than an air jet in the prior art.

Vorteilhafte Ausgestaltungen und Weiterbildungen des Verfahrens und der Vorrichtung gemäß der Erfindung ergeben sich aus den vom Anspruch 1 bzw. Anspruch 12 jeweils abhängigen Ansprüchen.Advantageous embodiments and further developments of the method and the device according to the invention will become apparent from the claims dependent respectively from claim 1 and claim 12.

Der oder die Primärgasströme werden im Allgemeinen wenigstens teilweise turbulent eingestellt, der oder die Sekundärgasströme hingegen wenigstens teilweise diffus und/oder wenigstens teilweise laminar.The primary gas stream (s) are generally at least partially turbulent, while the secondary gas stream (s) is at least partially diffused and / or at least partially laminar.

Die mittlere Strömungsgeschwindigkeit des oder jedes Primärgasstromes ist vorzugsweise wenigstens doppelt, insbesondere wenigstens fünfmal und vorzugsweise wenigstens zehnmal höher als die mittlere Strömungsgeschwindigkeit des oder jedes zugehörigen Sekundärgasstromes. Insbesondere beträgt die mittlere Strömungsgeschwindigkeit des oder jedes Primärgasstromes, zumindest am Anfang, zwischen etwa 6 m/s und etwa 20 m/s und/oder die mittlere Strömungsgeschwindigkeit des oder jedes Sekundärgasstromes, zumindest am Anfang, zwischen etwa 0,1 m/s und etwa 2 m/s.The average flow rate of the or each primary gas stream is preferably at least twice, in particular at least five times and preferably at least ten times higher than the mean flow velocity of the or each associated secondary gas stream. In particular, the average flow rate of the or each primary gas stream, at least initially, is between about 6 m / s and about 20 m / s and / or the mean flow velocity of the or each secondary gas stream, at least initially, between about 0.1 m / s and about 2 m / s.

Wenigstens ein und vorzugsweise jeder Primärgasstrom wird entlang einer vorgegebenen oder vorgebbaren Hauptströmungsrichtung eingestellt oder nach Art eines Strahles. Dabei ist es besonders vorteilhaft, wenn der Primärgasstrom den Sekundärgasstrom wenigstens annähernd parallel zum Primärgasstrom und/oder entlang der eingestellten Hauptströmungsrichtung ausrichtet und/oder stabilisiert.At least one and preferably each primary gas flow is adjusted along a predetermined or predefinable main flow direction or in the manner of a jet. It is particularly advantageous if the primary gas stream aligns and / or stabilizes the secondary gas flow at least approximately parallel to the primary gas flow and / or along the set main flow direction.

Der Sekundärgasstrom wiederum vermindert die Induktion von nicht-konditionierter Umgebungsluft durch den Primärgasstrom, insbesondere praktisch komplett.The secondary gas flow in turn reduces the induction of non-conditioned ambient air through the primary gas flow, in particular practically completely.

Zum Austritt oder Erzeugen des oder jedes Primärgasstromes ist wenigstens eine Primäraustrittsöffnung vorgesehen und für den oder jeden Sekundärgasstrom wenigstens eine die Primäröffnung(en) umgebende Sekundäraustrittöffnung.For discharging or generating the or each primary gas flow, at least one primary outlet opening is provided and for the or each secondary gas flow at least one secondary outlet opening surrounding the primary opening (s).

In einer besonders vorteilhaften Ausführungsform wird wenigstens ein Primärgasstrom in einen inneren Teilstrom und wenigstens einen äußeren Teilstrom aufgeteilt, wobei der Sekundärgasstrom zusammen mit dem äußeren Teilstrom des Primärgasstromes geleitet wird und den äußeren Teilstrom im Wesentlichen vollständig umgibt und der innere Teilstrom des Primärgasstromes zunächst innerhalb wenigstens eines Strömungskanals (Primärströmungskanal) getrennt vom äußeren Teilstrom geführt wird und stromabwärts wieder mit dem äußeren Teilstrom vereinigt wird. Dadurch lassen sich höhere Strömungsgeschwindigkeiten und/oder größere Stromlängen erreichen. Wenigstens ein äußerer Teilstrom des Primärgasstromes strömt vorzugsweise wenigstens teilweise an der Außenseite des Strömungskanals für den inneren Teilstrom entlang. Die Strömungsrichtung des inneren Teilstroms des Primärgasstromes im Strömungskanal entspricht im Allgemeinen zumindest beim Austritt aus dem Strömungskanal im Wesentlichen der Hauptströmungsrichtung des Primärgasstromes nach Vereinigung von innerem Teilstrom und äußerem Teilstrom.In a particularly advantageous embodiment, at least one primary gas stream is divided into an inner partial stream and at least one outer partial stream, wherein the secondary gas stream is passed together with the outer partial stream of the primary gas stream and the outer partial stream substantially completely surrounds and the inner partial stream of the primary gas stream initially within at least one Flow channel (primary flow channel) is guided separately from the outer partial flow and downstream is reunited with the outer partial flow. As a result, higher flow velocities and / or longer flow lengths can be achieved. At least one outer partial flow of the primary gas flow preferably flows at least partially along the outer side of the flow channel for the inner partial flow. The flow direction of the inner partial flow of the primary gas flow in the flow passage generally corresponds at least at the exit from the flow passage substantially the main flow direction of the primary gas flow after union of the inner partial flow and outer partial flow.

In einer besonderen Weiterbildung ist bzw. wird der Primärgasstrom oder der innere Teilstrom des Primärgasstromes oder der Strömungskanal innerhalb eines vorgegebenen Raumwinkelbereiches einstellbar bzw. bewegt, insbesondere fortlaufend oder periodisch und/oder schwenkend, pendelnd oder kreisend. Der zu konditionierende oder konditionierte Prozessbereich liegt dann im Allgemeinen innerhalb des vom Primärgasstrom oder dessen inneren Teilstrom erfassten Raumwinkelbereiches.In a particular embodiment, the primary gas flow or the inner partial flow of the primary gas flow or the flow channel can be adjusted or moved within a predetermined solid angle range, in particular continuously or periodically and / or pivotally, oscillatingly or circling. The process area to be conditioned or conditioned is then generally within the solid angle range detected by the primary gas flow or its inner partial flow.

Vorzugsweise nimmt, stromabwärts gesehen, der Konditioniergasstrom in seinem Strömungsquerschnitt zunächst ab bis zu einem Verengungsbereich, in dem der Konditioniergasstrom den kleinsten Strömungsquerschnitt aufweist, und weitet sich dann wieder auf. Dieser Verengungsbereich des Konditioniergasstromes wird in den zu konditionierenden oder konditionierten Prozessbereich gelegt.Preferably, seen downstream, the conditioning gas stream initially decreases in its flow cross-section to a constriction area in which the conditioning gas flow has the smallest flow cross-section, and then widens again. This narrowing zone of the conditioning gas stream is placed in the process area to be conditioned or conditioned.

Die Querabmessungen des Sekundärgasstromes von dem Primärgasstrom nach außen gemessen oder der Strömungsquerschnitt des Sekundärgasstromes sind in einer bevorzugten Ausführungsform größer als die entsprechende Abmessungen bzw. der entsprechende Strömungsquerschnitt des Primärgasstromes, insbesondere um wenigstens einen Faktor 2, vorzugsweise um wenigstens einen Faktor 4 und insbesondere bis einen Faktor 10.In a preferred embodiment, the transverse dimensions of the secondary gas flow measured from the primary gas flow to the outside or the flow cross section of the secondary gas flow are greater than the corresponding dimensions or the corresponding flow cross section of the primary gas flow, in particular by at least a factor of 2, preferably by at least a factor of 4 and in particular to one Factor 10.

Die Längsabmessung des Sekundärgasstromes und/oder des Primärgasstromes ist stromabwärts gesehen bis zum Prozessbereich vorzugsweise zwischen 0,1 m und 1,5 m gewählt.The longitudinal dimension of the secondary gas stream and / or the primary gas stream downstream, as far as the process area, is preferably selected between 0.1 m and 1.5 m.

In einer Ausführungsform weist wenigstens ein Primärgasstrom bzw. wenigstens eine Primäraustrittsöffnung einen im Wesentlichen rechteckigen und/oder langgestreckten und/oder langschlitzförmigen Strömungsquerschnitt auf. In einer anderen Ausführungsform ist der Strömungsquerschnitt wenigstens eines Primärgasstromes oder wenigstens einer Primäraustrittsöffnung in sich geschlossen um einen Innenraum verlaufend, insbesondere ringförmig, ausgebildet. Wenigstens eine Primäraustrittsöffnung ist bevorzugt als Düse ausgebildet.In one embodiment, at least one primary gas stream or at least one primary outlet opening has a substantially rectangular and / or elongate and / or long slot-shaped flow cross-section. In another embodiment, the flow cross-section of at least one primary gas stream or at least one primary outlet opening closed in itself, extending around an interior, in particular annular, is formed. At least one primary outlet opening is preferably designed as a nozzle.

Ein Sekundärgasstrom kann in einer besonderen Ausführungsform im Innenraum innerhalb eines Primärgasstromes und ein weiterer Sekundärgasstrom an der vom Innenraum abgewandten Außenseite des Primärgasstromes erzeugt werden, insbesondere in konzentrischer Anordnung. Ferner können wenigstens zwei Primärgasströme in wenigstens einem gemeinsamen Sekundärgasstrom eingebettet oder von diesem umgeben sein.In a particular embodiment, a secondary gas stream can be generated in the interior space within a primary gas stream and a further secondary gas stream can be generated at the outside of the primary gas stream facing away from the interior, in particular in a concentric arrangement. Furthermore, at least two primary gas streams may be embedded in or surrounded by at least one common secondary gas stream.

Vorzugsweise ist wenigstens einen Gruppe von mehreren Sekundäraustrittsöffnungen vorgesehen, die um die wenigstens eine oder eine Gruppe von Primäraustrittsöffnung(en) angeordnet sind. Wenigstens eine Gruppe von Sekundäraustrittsöffnungen kann sich dabei über einen im Wesentlichen von einem Rechteck begrenzten Bereich erstrecken und/oder im Wesentlichen in einer gemeinsamen Gruppenebene liegen, die vorzugsweise im Wesentlichen parallel zu einer Austrittsebene wenigstens einer Primäraustrittsöffnung liegt oder mit dieser Austrittsebene zusammenfällt oder geneigt, insbesondere senkrecht, zu einer Austrittsebene wenigstens einer Primäraustrittsöffnung ist.Preferably, at least one group of a plurality of secondary outlet openings is provided, which are arranged around the at least one or a group of primary outlet opening (s). At least one group of secondary outlet openings may extend over an area essentially bounded by a rectangle and / or lie substantially in a common group plane, which is preferably substantially parallel to an exit plane of at least one primary exit opening or coincides or inclined, in particular, with this exit plane perpendicular to an exit plane of at least one primary outlet opening.

Die Primäraustrittsöffnung(en) und die zugehörigen Sekundäraustrittsöffnung(en) wenigstens eines Konditioniergasstromes stehen mit einem gemeinsamen Zuleitkanal in Strömungsverbindung, so dass das Konditioniergas aus diesem Zuleitkanal sowohl den wenigstens einen Primärgasstrom als auch den wenigstens einen Sekundärgasstrom des Konditioniergasstromes bildet. Es sind aber auch voneinander getrennte zugehörige Zuleitkanälen zum Zuleiten jeweils eines Konditioniergases möglich..The primary outlet opening (s) and the associated secondary outlet opening (s) of at least one conditioning gas flow are in fluid communication with a common supply channel, so that the conditioning gas from this supply channel forms both the at least one primary gas stream and the at least one secondary gas stream of the conditioning gas stream. But there are also separate associated Zuleitkanälen for supplying each of a conditioning gas possible.

Die Mittel zum Erzeugen des Konditioniergasstromes umfassen zweckmäßigerweise wenigstens ein Gehäuse, in dessen Gehäusewandung wenigstens in einem Austrittsbereich die Primäraustrittsöffnung(en) und die Sekundäraustrittsöffnung(en) gebildet sind. In einem vom Austrittsbereich verschiedenen, mit den Zuleitmitteln verbundenen oder an den Zuleitkanal angrenzenden Eintrittsbereich der Gehäusewandung sind in einer Ausführungsform wenigstens eine Primäreintrittsöffnung, die mit der oder den Primäraustrittsöffnung(en) in Strömungsverbindung stehen oder bringbar ist, und wenigstens eine Sekundäreintrittsöffnung, die mit der oder den Sekundäraustrittsöffnung(en) in Strömungsverbindung steht oder bringbar ist, gebildet.The means for generating the conditioning gas stream expediently comprise at least one housing, in the housing wall of which the primary outlet opening (s) and the secondary outlet opening (s) are formed at least in one outlet region. In one of the outlet region, connected to the Zuleitmitteln or adjacent to the Zuleitkanal inlet region of the housing wall are in one embodiment, at least one primary inlet opening in fluid communication with the or the primary outlet opening (s) or can be brought, and at least one secondary inlet opening, with the or the secondary outlet opening (s) is in flow connection or can be brought formed.

Es ist vorteilhaft, wenn der Strömungsquerschnitt der Primäreintrittsöffnung(en) und/oder der Sekundäreintrittsöffnung(en) und dadurch der Volumenstrom des durchtretenden Konditioniergases mittels einer, insbesondere verschiebbaren, Mengeneinstelleinrichtung einstellbar ist.It is advantageous if the flow cross-section of the primary inlet opening (s) and / or the secondary inlet opening (s) and thereby the volume flow of the passing Konditioniergases is adjustable by means of a, in particular displaceable, Mengeneinstelleinrichtung.

Im Gehäuse kann wenigstens ein Primärströmungskanal gebildet sein, der die Primäreintrittsöffnung(en) mit der oder den Primäraustrittsöffnung(en) verbindet und in dem vorzugsweise Strömungsgleichrichter zur Gleichrichtung und/oder Vergleichmäßigung der Strömung angeordnet oder anordenbar sind.In the housing, at least one primary flow channel can be formed, which connects the primary inlet opening (s) to the primary outlet opening (s) and in which preferably flow rectifiers are arranged or can be arranged for rectification and / or equalization of the flow.

Das Gehäuse weist vorzugsweise an entgegengesetzten Seiten des Primärströmungskanals zwei, insbesondere im Wesentlichen symmetrisch zum Primärströmungskanal ausgebildete, Gehäuseteile auf, an deren Außenwänden sowohl die Sekundäreintrittsöffnung(en) als auch die Sekundäraustrittsöffnung(en) angeordnet sind und in denen jeweils ein Sekundärströmungskanal ausgebildet ist, der die Sekundäreintrittsöffnung(en) mit der oder den Sekundäraustrittsöffnung(en) verbindet.The housing preferably has on two opposite sides of the primary flow channel two housing parts, in particular substantially symmetrical to the primary flow channel, on whose outer walls both the secondary inlet opening (s) and the secondary outlet opening (s) are arranged and in each of which a secondary flow channel is formed, which connects the secondary inlet opening (s) with the or the secondary outlet opening (s).

Ferner kann innerhalb des Gehäuses im Strömungsweg zwischen der oder den Sekundäreintrittsöffnung(en) und der oder den Sekundäraustrittsöffnung(en) wenigstens ein Vorverteiler mit einer Vielzahl von Durchtrittöffnungen angeordnet sein.Furthermore, at least one pre-distributor with a plurality of passage openings can be arranged within the housing in the flow path between the secondary inlet opening (s) and the secondary outlet opening (s).

In der Ausführungsform gemäß FIG 1 ist ein Zuleitkanal 7 einer Konditioniervorrichtung gezeigt, der horizontal verläuft und durch den in Richtung des dargestellten Pfeils ein Konditioniergas 6 zugeleitet wird, das mit einer Konditioniergröße K konditioniert ist. An der Unterseite des Zuleitkanals 7 sind oberhalb zweier getrennter Prozessbereiche 5 und 5' einer nicht weiter dargestellten Prozessanlage, in denen Prozesse oder Teilprozesse durchgeführt werden, jeweils ein Gehäuse 10 bzw. 10' der Konditioniervorrichtung angeordnet.In the embodiment according to FIG. 1 a Zuleitkanal 7 a conditioning device is shown, which extends horizontally and is fed through the direction of the arrow shown a conditioning gas 6, which is conditioned with a K conditioningiergröße. At the bottom of Zuleitkanals 7 are above two separate process areas 5 and 5 'of a process plant, not shown, in which processes or sub-processes are performed, each a housing 10 or 10' of the conditioning arranged.

An einer dem Zuleitkanal 7 zugewandten Oberseite des Gehäuses 10 und 10' sind Eintrittsöffnungen gebildet, durch die Konditioniergas 6 in das Gehäuse 10 bzw. 10' eintreten kann. Beim Gehäuse 10 sind eine Primäreintrittöffnung mit 23 und Sekundäreintrittsöffnungen mit 26 bezeichnet. Bei dem Gehäuse 10' sind die Eintrittöffnungen nicht weiter spezifiziert. An einer nach unten gerichteten Unterseite der Gehäuse 10 bzw. 10' sind Austrittsöffnungen vorgesehen, aus denen das Konditioniergas 6 nach unten zu dem zugehörigen Prozessbereich 5 bzw. 5' hin austritt. Diese Austrittsöffnungen umfassen in FIG 1 jeweils eine zentrale Primäraustrittsöffnung 13 bzw. 13' und diese Primäraustrittsöffnung 13 bzw. 13' umgebende Sekundäraustrittsöffnungen 14 bzw. 14' am Gehäuse 10 bzw. 10'.At one of the Zuleitkanal 7 facing top of the housing 10 and 10 'inlet openings are formed, can enter through the conditioning gas 6 in the housing 10 or 10'. In the case 10, a primary inlet opening with 23 and secondary inlet openings are designated by 26. In the housing 10 ', the inlet openings are not further specified. On a downwardly directed bottom of the housing 10 and 10 'outlet openings are provided, from which the conditioning gas 6 down to the associated process area 5 and 5' emerges out. These outlet openings comprise in FIG. 1 in each case a central primary outlet opening 13 or 13 'and this primary outlet opening 13 or 13' surrounding secondary outlet openings 14 and 14 'on the housing 10 or 10'.

Die Primäreintrittsöffnung 23 an der Oberseite des Gehäuses 10 ist zur Weiterleitung des aus dem Zuleitkanal 7 durch sie durchtretenden Konditioniergases 6 zur Primäraustrittsöffnung 13 hin mit der Primäraustrittsöffnung 13 an der Unterseite des Gehäuses 10 über einen zentralen schlitzförmigen Primärströmungskanal 15 verbunden und weist gemäß FIG 1 dieselbe Breite auf wie die Primäraustrittsöffnung 13. Die Sekundäreintrittsöffnungen 24 des Gehäuses 10 sind mit den Sekundäraustrittöffnungen 14 über einen oder mehrere Sekundärströmungskanäle 16 zum Weiterleiten des Konditioniergases 6 verbunden.The primary inlet opening 23 at the top of the housing 10 is for forwarding the passing of the Zuleitkanal 7 through them conditioning gas 6 to the primary outlet opening 13 with the primary outlet opening 13 on the underside of the housing 10 via a central slot-shaped primary flow channel 15 connected and points according FIG. 1 the same width as the primary outlet opening 13. The secondary inlet openings 24 of the housing 10 are connected to the secondary outlet openings 14 via one or more secondary flow channels 16 for forwarding the conditioning gas 6.

Die Strömungsführung und Gestaltung der Auslässe für das Konditioniergas 6 im Gehäuse 10 bzw. 10' sind nun so gewählt, dass aus der Primäraustrittsöffnung 13 bzw. 13' ein schnell fließender Primärgasstrom 3 bzw. 13' austritt, der gemäß der mit einem Pfeil gekennzeichneten Strömungsgeschwindigkeit VP bzw. VP' nach unten auf den Prozessbereich 5 bzw. 5' gerichtet ist, und aus den vielen kleinen Sekundäraustrittsöffnungen 14 bzw. 14' ein Sekundärgasstrom 4 bzw. 4' austritt, der den Primärgasstrom 3 bzw. 3' ringsum umgibt und mit einer wesentlich geringeren Strömungsgeschwindigkeit VS bzw. VS' strömt als der Primärgasstrom 3 bzw. 3'.The flow guidance and design of the outlets for the conditioning gas 6 in the housing 10 or 10 'are now selected so that from the primary outlet opening 13 or 13', a fast-flowing primary gas stream 3 or 13 'emerges, according to the flow velocity indicated by an arrow VP and VP 'down to the process area 5 and 5' is directed, and from the many small secondary outlet openings 14 and 14 ', a secondary gas stream 4 or 4' emerges, surrounding the primary gas stream 3 and 3 'around and with a substantially lower flow velocity VS or VS 'flows than the primary gas flow 3 or 3'.

Der Primärgasstrom 3 wird durch Einstellung der Strömungsgeschwindigkeit VP in Abhängigkeit von dem verwendeten Konditioniergas 6 als turbulente Strömung eingestellt. Die Primäraustrittsöffnung 13 und die Primäreintrittsöffnung 23 bilden vorzugsweise zusammen mit dem sie verbindenden Primärströmungskanal 15 eine Düse, insbesondere eine Schlitzdüse. Der den Primärgasstrom 3 umgebende Sekundärgasstrom 4 wird als diffuse Strömung oder wenigstens teilweise laminare Strömung erzeugt. Die mittlere Strömungsgeschwindigkeit VS bzw. VS' des Sekundärgasstromes 4 bzw. 4' wird insbesondere aufgrund des hohen Strömungswiderstands der Sekundäraustrittsöffnungen 14 bzw. 14' und der Verwirbelung im Sekundärströmungskanal 16 niedrig gehalten und insbesondere kleiner als VP bzw. VP'.The primary gas flow 3 is set by adjusting the flow velocity VP as a function of the conditioning gas 6 used as a turbulent flow. The primary outlet opening 13 and the primary inlet opening 23 preferably together with the primary flow channel 15 connecting them form a nozzle, in particular a slot nozzle. The secondary gas flow 4 surrounding the primary gas flow 3 is generated as a diffuse flow or at least partially laminar flow. The average flow velocity VS or VS 'of the secondary gas flow 4 or 4' is kept low, in particular due to the high flow resistance of the secondary outlet openings 14 and 14 'and the turbulence in the secondary flow channel 16, and in particular smaller than VP or VP'.

Die Strömungsgeschwindigkeit VP des Primärgasstromes 3 wird üblicherweise zwischen 6 m/s und 20 m/s eingestellt. Die Strömungsgeschwindigkeit VS des Sekundärgasstromes 4 liegt deutlich darunter, üblicherweise bei 0,1 m/s bis 2 m/s.The flow velocity VP of the primary gas stream 3 is usually set between 6 m / s and 20 m / s. The flow velocity VS of the secondary gas flow 4 is significantly lower, usually at 0.1 m / s to 2 m / s.

Aufgrund seiner hohen Strömungsgeschwindigkeit VP bzw. VP' führt der Primärgasstrom 3 bzw. 3' den langsameren Sekundärgasstrom 4 bzw. 4' infolge der dadurch bewirkten Sogwirkung oder Induktion mit, so dass der Sekundärgasstrom 4 bzw. 4' trotz seines zunächst wesentlich ungerichteteren Charakters dennoch eine Richtcharakteristik erhält und im Wesentlichen parallel zum Primärgasstrom 3 bzw. 4' mitgeführt wird.Due to its high flow velocity VP or VP ', the primary gas flow 3 or 3' carries the slower secondary gas flow 4 or 4 'as a result of the suction effect or induction caused thereby, so that the Secondary gas stream 4 or 4 'still receives a directional characteristic despite its initially substantially underengered character and is carried substantially parallel to the primary gas stream 3 and 4'.

Der Primärgasstrom 3 bzw. 3' bleibt aufgrund der hohen Strömungsgeschwindigkeit VP bzw. VP' relativ gebündelt oder divergiert nur wenig. Der Sekundärgasstrom 4 bzw. 4' konvergiert zunächst aufgrund der strömungsdynamischen Bedingungen bis zu einem Verengungsbereich 20 bzw. 20' und weitet sich dann wieder auf (oder: divergiert). Der aus Primärgasstrom 3 bzw. 3' und Sekundärgasstrom 4 bzw. 4' zusammengesetzte Konditioniergasstrom 2 bzw. 2' wird nun so eingestellt, dass die Verengungsstelle oder der Verengungsbereich 20 bzw. 20' im Prozessbereich 5 bzw. 5' zu liegen kommt, die Länge 1 bzw. 1' des Konditioniergasstromes 2 bzw. 2' von den Austrittsöffnungen 13 bzw. 13' und 14 bzw. 14' in Strömungsrichtung zum Prozessbereich 5 bzw. 5' also einen konvergierenden Bereich des Sekundärgasstromes 4 bzw. 4' abdeckt. Den Prozessbereich 5 bzw. 5' in den fokussierten Bereich bzw. Verengungsbereichs 20 bzw. 20' des Konditioniergasstromes 2 bzw. 2' zu legen hat den Vorteil einer genaueren Einstellung der Konditioniergröße K. Der Verengungsbereich 20 stellt in den meisten Anwendungen den maximalen Abstand 1 bzw. 1' zwischen Luftauslass und Prozessbereich 5 dar, bei dem die unterschiedlichen Strömungsgeschwindigkeiten VP und VS von Primärgasstrom 3 und Sekundärgasstrom 4 noch wirksam werden.The primary gas flow 3 or 3 'remains relatively concentrated due to the high flow velocity VP or VP' or diverges only slightly. The secondary gas stream 4 or 4 'initially converges due to the fluid-dynamic conditions up to a constriction region 20 or 20' and then expands again (or: diverges). The conditioning gas stream 2 or 2 'composed of primary gas flow 3 or 3' and secondary gas flow 4 or 4 'is now adjusted so that the constriction point or narrowing region 20 or 20' comes to lie in the process region 5 or 5 ', respectively Length 1 or 1 'of the conditioning gas flow 2 or 2' from the outlet openings 13 or 13 'and 14 or 14' in the flow direction to the process area 5 or 5 'thus covers a convergent region of the secondary gas flow 4 or 4'. Laying the process area 5 or 5 'in the focused area or narrowing area 20 or 20' of the conditioning gas stream 2 or 2 'has the advantage of a more precise setting of the conditioning size K. The narrowing area 20 sets the maximum distance 1 in most applications or 1 'between air outlet and process area 5, in which the different flow velocities VP and VS of primary gas stream 3 and secondary gas stream 4 are still effective.

Der Druckunterschied zwischen dem Zuleitkanal 7 und dem stromabwärts gelegenen Bereich, in den der Konditioniergasstrom 2 bzw. 2' strömt, insbesondere im Prozessbereich 5 bzw. 5' wird typischerweise zwischen 100 Pa und 500 Pa.
eingestellt und ist abhängig von der konkreten Ausführungsform der Strömungsführung und der Strömungsauslässe im Gehäuse 10 bzw. 10' sowie den gewünschten Strömungsgeschwindigkeiten VP bzw. VP' und VS bzw. VS' für den Primärgasstrom 3 bzw. 3' und den Sekundärgasstrom 4 bzw. 4'.The pressure difference between the feed duct 7 and the downstream area into which the conditioning gas flow 2 or 2 'flows, in particular in the process area 5 or 5', is typically between 100 Pa and 500 Pa.
is set and depends on the concrete embodiment of the flow guide and the flow outlets in the housing 10 or 10 'and the desired flow velocities VP or VP' and VS or VS 'for the primary gas stream 3 or 3' and the secondary gas stream 4 and 4 respectively '.

Es wird also ein Doppelgasstrom mit unterschiedlichen Strömungsgeschwindigkeiten mit einer innenliegenden Schlitzdüse und äußerem, die Schlitzdüse umgebenden Diffusauslass erzeugt. Der Primärgasstrom 3 bzw. 3' dient als Stützstrahl für den Sekundärgasstrom 4 bzw. 4'. Durch die hohe Strömungsgeschwindigkeit VP bzw. VP' des Primärgasstromes 3 bzw. 3' reinigt dieser den angeblasenen Prozessbereich 5 bzw. 5' und darin befindliche Prozessanlagenteile oder Maschinenteile oder zu verarbeitende Produkte von Staubablagerungen. Ferner stabilisiert der Primärgasstrom 3 bzw. 3' die eingestellte Richtung des gesamten Konditioniergasstromes 2 bzw. 2' und erhöht die Eindringtiefe des ihn umgebenden, diffusen Sekundärgasstromes 4 bzw. 4'. Der diffuse und mit geringer Strömungsgeschwindigkeit VS austretende Sekundärgasstrom 4 verhindert dagegen die Induktion von nicht konditionierter Umgebungsluft 28 und vermindert insbesondere den Eintritt von Staubpartikeln aus der Umgebungsluft 28 in den Konditioniergasstrom 2 bzw. 2'.Thus, a double gas flow with different flow velocities is generated with an internal slot nozzle and outer diffuser outlet surrounding the slot nozzle. The primary gas flow 3 or 3 'serves as a support jet for the secondary gas flow 4 or 4'. Due to the high flow velocity VP or VP 'of the primary gas flow 3 or 3', it cleans the blown process area 5 or 5 'and any process plant parts or machine parts or products of dust deposits to be processed therein. Furthermore, the primary gas stream 3 or 3 'stabilizes the set direction of the entire conditioning gas stream 2 or 2' and increases the penetration depth of the surrounding, diffuse secondary gas stream 4 or 4 '. By contrast, the diffused secondary gas flow 4 exiting at a low flow velocity VS prevents the induction of unconditioned ambient air 28 and, in particular, reduces the entry of dust particles from the ambient air 28 into the conditioning gas flow 2 or 2 '.

Wie in FIG 1 angedeutet, können beliebig viele Prozessbereiche 5, 5' oder Maschinenzonen durch in der Vorrichtung integrierte Verteilorgane wie die Gehäuse 10 bzw. 10' mit konditioniertem Gas versorgt werden.As in FIG. 1 As indicated, any number of process areas 5, 5 'or machine zones can be supplied with conditioned gas by means of distribution devices integrated in the device, such as housings 10 and 10'.

FIG 2 zeigt nun eine konkrete Ausführungsform einer Vorrichtung zum Konditionieren eines Prozessbereiches 5 mit einem langgestreckten Gehäuse 10 zum Erzeugen eines langgestreckten Konditioniergasstromes 2. Das Gehäuse 10 umfasst zwei symmetrisch bezüglich einer Mittelebene M (die in FIG 2 nur als Mittelachse M im vorderen Querschnitt dargestellt ist) angeordnete und ausgebildete Gehäuseteile 17 und 18, die im Bereich der Mittelebene M durch einen Primärströmungskanal 15, der als Längsschlitz ausgebildet ist, voneinander getrennt sind. FIG. 2 now shows a concrete embodiment of a device for conditioning a process area 5 with an elongated housing 10 for generating an elongated conditioning gas flow 2. The housing 10 comprises two symmetrical with respect to a median plane M (which in FIG. 2 only as a central axis M in the front cross-section is shown) and formed housing parts 17 and 18, which are separated in the region of the median plane M by a primary flow channel 15 which is formed as a longitudinal slot.

Es ist wieder ein Zuleitkanal 7 für Konditioniergas 6 oberhalb des Gehäuses 10 angeordnet. Auf den dem Zuleitkanal 7 zugewandten oberen Flachseiten der Gehäuseteile 17 und 18 ist eine den Primärströmungskanal 15 überdeckende, plattenförmige Mengeneinstelleinrichtung 30 angeordnet. Die beiden Gehäuseteile 17 und 18 werden mit den Seitenteilen des Gehäuses verbunden oder integriert.It is again a Zuleitkanal 7 for conditioning 6 arranged above the housing 10. On the Zuleitkanal 7 facing upper flat sides of the housing parts 17 and 18, a primary flow channel 15 overlapping, plate-shaped Mengeneinstelleinrichtung 30 is arranged. The two housing parts 17 and 18 are connected or integrated with the side parts of the housing.

Die Mengeneinstelleinrichtung 33 umfasst eine zentrale, oberhalb des Primärströmungskanals 15 zwischen den beiden Gehäuseteilen 17 und 18 verlaufende Schlitzreihe mit linear hintereinander und unter Abstand zueinander angeordneten schlitzförmigen Primäreintrittsöffnungen 23 und an beiden Seiten der Reihe der Primäreintrittsöffnungen 23 jeweils eine dazu parallele Reihe von voneinander beabstandeten hintereinander angeordneten Sekundäreintrittsöffnungen 24. Die Sekundäreintrittsöffnungen 24 sind in FIG 2 rund und mit jeweils einer Stauplatte 34 versehen. Über die geöffneten Sekundäreintrittsöffnungen gelangt von dem Zuleitkanal 7 eine durch den Strömungsquerschnitt dieser offenen Sekundäreintrittsöffnungen 24 festgelegte Menge (Volumenstrom oder Massenstrom) von Konditioniergas 6 in jeweils einen Sekundärströmungskanal 16 innerhalb des zugehörigen Gehäuseteils 17 und 18, wie durch die Pfeile teilweise angedeutet.The Mengeneinstelleinrichtung 33 comprises a central, above the primary flow channel 15 between the two housing parts 17 and 18 extending row of slots with linearly one behind the other and spaced apart slot-shaped primary inlet openings 23 and arranged on both sides of the row of primary inlet openings 23 each have a parallel row of spaced apart one behind the other Secondary inlet openings 24. The secondary inlet openings 24 are in FIG. 2 around and provided with a respective baffle 34. Via the opened secondary inlet openings, a quantity (volume flow or mass flow) of conditioning gas 6, which is defined by the flow cross section of these open secondary inlet openings 24, passes from the supply channel 7 into a respective secondary flow channel 16 within the associated housing part 17 and 18, as partially indicated by the arrows.

Das durch die Sekundäreintrittsöffnungen 24 eingetretene Konditioniergas 6 wird durch einen, insbesondere als Lochblech ausgebildeten, Vorverteiler 19 mit einzelnen Öffnungen in einen weiteren Sekundärströmungsraum 36 innerhalb des Gehäuseteils 17 bzw. 18 geführt und gelangt anschließend über an der seitlichen und unteren Außenwand des Gehäuses 10 bzw. der Gehäuseteile 17 und 18 der Gehäusewandung 11 angeordnete Sekundäraustrittsöffnungen 14 als Sekundärgasstrom 4 nach außen, wie durch die Strömungspfeile angedeutet.The occurred through the secondary inlet openings 24 conditioning gas 6 is passed through a, designed in particular as a perforated plate, pre-manifold 19 with individual openings in a further secondary flow space 36 within the housing part 17 and 18 and then passes through on the lateral and lower outer wall of the housing 10 and the housing parts 17 and 18 of the housing 11 arranged secondary outlet openings 14 as a secondary gas stream 4 to the outside, as indicated by the flow arrows.

Die durch die Primäreintrittsöffnungen 23 aus dem Zuleitkanal 7. einströmende Strömung des Konditioniergases 6 wird in dem Primärströmungskanal 15 ausgerichtet und strömt in einer fest durch den Primärströmungskanal 15 vorgegebenen Richtung, die im Beispiel der FIG 2 nach unten, das heißt parallel zur Schwerkraft, gerichtet ist, aus der Primäraustrittsöffnung 13 als Primärgasstrom 3 aus. In dem Primärströmungskanal 15 sind vorzugsweise Gleichrichter angeordnet, die die Strömung entlang der Hauptströmungsrichtung gleichrichten, beispielsweise eine Anordnung von nebeneinander angeordneten, beispielsweise rechteckigen Rohren, die durch Wände voneinander getrennt sind.The flowing through the primary inlet openings 23 from the Zuleitkanal 7 flow of Konditioniergases 6 is aligned in the primary flow channel 15 and flows in a fixed predetermined by the primary flow channel 15 direction, which in the example of FIG. 2 down, that is parallel to gravity, is directed, from the primary outlet opening 13 as the primary gas stream 3 from. In the primary flow channel 15, rectifiers are preferably arranged which rectify the flow along the main flow direction, for example an arrangement of juxtaposed, for example rectangular, tubes which are separated from one another by walls.

Die Mengeneinstellung erfolgt vorzugsweise durch Verschieben der Mengeneinstelleinrichtung 33, und zwar beim Sekundärgasstrom 4 in Längsrichtung und beim Primärgasstrom 3 in Querrichtung und die dadurch bewirkte Veränderung des Strömungsquerschnittes der Sekundäreintrittsöffnungen 24 bzw. Primäreintrittsöffnungen 23.The amount adjustment is preferably carried out by moving the Mengeneinstelleinrichtung 33, namely the secondary gas stream 4 in the longitudinal direction and the primary gas flow 3 in the transverse direction and the change in the flow cross-section of the secondary inlet openings 24 or primary inlet openings 23 caused thereby.

FIG 5 zeigt den Austritt des Primärgasstromes 3 aus der Primäraustrittsöffnung 13 gemäß FIG 2 in einer vergrößerten und detaillierteren Ansicht. FIG. 5 shows the exit of the primary gas stream 3 from the primary outlet opening 13 according to FIG. 2 in an enlarged and more detailed view.

Der Primärgasstrom 3 wird gemäß FIG 2 und 5 unmittelbar nach Austreten aus der Primäraustrittsöffnung 13 in einen inneren Primärteilstrom 31 und in einen äußeren Primärteilstrom 32 aufgeteilt. Der innere Teilstrom 31 strömt durch einen sich an die Primäraustrittsöffnung 13 anschließenden Primärteilstromkanal 27, im Beispiel der FIG 2 nach unten, entlang seiner Hauptströmungsrichtung weiter und tritt dann versetzt zu dem zugleich an der Außenseite des Primärteilstromkanals 27 entlang strömenden äußeren Teilstrom 32 an dem von der Primäraustrittsöffnung 13 abgewandten Mündungsbereich oder Primärteilstromaustritt 29 aus und vereinigt sich dann wieder mit dem äußeren Teilstrom 32 zu einem einheitlichen Primärgasstrom 3. Die diffus aus den Sekundäraustrittsöffnungen 14 ausgetretene Strömung des Konditioniergases 6 bildet einen (diffusen) Sekundärgasstrom 4, der von der Richtwirkung des Primärgasstromes 3 ebenfalls nach unten ausgerichtet wird und den Primärgasstrom 3 einhüllt. Die Kombination aus Primärgasstrom 3 und 4 bildet wieder einen Konditioniergasstrom 2, der, insbesondere im Bereich der Verengung 20, dem zu konditionierenden Prozessbereich 5 zugeführt wird.The primary gas stream 3 is according to FIG. 2 and 5 immediately after exiting the primary outlet opening 13 into an inner primary part stream 31 and split into an outer primary part stream 32. The inner partial flow 31 flows through a primary partial flow channel 27 adjoining the primary outlet opening 13, in the example of FIG FIG. 2 down, along its main flow direction and then moves offset to the same at the same time on the outside of the Primärteilstromkanals 27 along outer partial flow 32 at the side facing away from the primary outlet opening 13 orifice portion primary exit 29 and then reunites with the outer partial flow 32 to a single Primary gas flow 3. The diffused from the secondary outlet openings 14 flow of Konditioniergases 6 forms a (diffuse) secondary gas stream 4, which is also aligned by the directivity of the primary gas stream 3 down and envelops the primary gas stream 3. The combination of primary gas stream 3 and 4 again forms a conditioning gas stream 2 which, in particular in the region of the constriction 20, is fed to the process region 5 to be conditioned.

Neben der in FIG 2 dargestellten schlitzförmigen Primäraustrittsöffnung 13 und der entsprechend langgestreckten rechteckigen Strömungsführung des Primärgasstromes 3 und des gesamten Konditioniergasstromes 2 sind auch andere Topologien des Konditioniergasstromes 2 mit unterschiedlich angeordneten oder unterschiedlichen Anzahlen von Primärgasströmen und Sekundärgasströmen möglich.In addition to the in FIG. 2 shown slot-shaped primary outlet opening 13 and the corresponding elongated rectangular flow guidance of the primary gas stream 3 and the entire conditioning 2, other topologies of Konditioniergasstromes 2 with different or different numbers of primary gas streams and secondary gas streams are possible.

FIG 3 und 4 zeigen in zwei verschiedenen Ansichten ein Ausführungsbeispiel mit konzentrisch angeordneten Primärgasströmen und Sekundärgasströmen bzw. Primäraustrittsöffnungen und Sekundäraustrittsöffnungen. 3 and 4 show in two different views an embodiment with concentrically arranged primary gas streams and secondary gas streams or primary outlet openings and secondary outlet openings.

Aus einer zentralen Primäraustrittsöffnung 13 tritt durch einen Primärströmungskanal 15 geströmtes Konditioniergas 6 als zentraler Primärgasstrom 3 aus. Die zentrale Primäraustrittsöffnung 13 und der zentrale Primärgasstrom 3 haben einen im Wesentlichen kreisscheibenförmigen Querschnitt. Die Primäraustrittsöffnung 13 ist umgeben von einer Vielzahl von Sekundäraustrittsöffnungen 21, die einen den zentralen Primärgasstrom 3 umgebenden ersten Sekundärgasstrom 4 erzeugen, der einen im Wesentlichen ringförmigen Strömungsquerschnitt hat.From a central primary outlet opening 13, conditioning gas 6, which has flowed through a primary flow channel 15, exits as a central primary gas stream 3. The central primary outlet opening 13 and the central primary gas flow 3 have a substantially circular disk-shaped cross-section. The primary outlet opening 13 is surrounded by a multiplicity of secondary outlet openings 21 which generate a first secondary gas flow 4 surrounding the central primary gas flow 3 and which has a substantially annular flow cross-section.

Um die Sekundäraustrittsöffnung 21 ist nun wiederum konzentrisch zur zentralen Primäraustrittsöffnung 13 eine Ringspaltöffnung oder in sich geschlossene Primäraustrittsöffnung 12 vorgesehen. Die Primäraustrittsöffnung 12 ist über einen ringförmigen Primärströmungskanal 25 mit dem Zuleitkanal 7 verbunden und erzeugt einen ringförmigen Primärgasstrom 8, der den inneren Sekundärgasstrom 4 umschließt. Dieser zweite Primärgasstrom 8 wird nun wiederum von einem äußeren Sekundärgasstrom 9 umhüllt, der mittels die zweite Primäraustrittsöffnung 12 umgebenden äußeren Sekundäraustrittsöffnungen 22 erzeugt wird. Die äußeren Sekundäraustrittsöffnungen 22 sind ähnlich wie in FIG 2 über jeweils einen Sekundärströmungskanal 26 im Gehäuse 10 und nicht weiter bezeichnete Eintrittsöffnungen und Sekundärteintrittsöffnungen mit dem Zuleitkanal 7 verbunden.To the secondary outlet opening 21 is now in turn concentric with the central primary outlet opening 13 an annular gap opening or self-contained primary outlet opening 12 is provided. The primary outlet opening 12 is connected via an annular primary flow channel 25 to the supply channel 7 and generates an annular primary gas stream 8, which encloses the inner secondary gas stream 4. This second primary gas stream 8 is now in turn enveloped by an outer secondary gas stream 9, which is generated by means of the second primary outlet opening 12 surrounding outer secondary outlet openings 22. The outer secondary outlet openings 22 are similar to FIG FIG. 2 connected in each case via a secondary flow channel 26 in the housing 10 and not further designated inlet openings and secondary inlet openings with the supply channel 7.

Bei dieser Ausführungsform können die beiden Primärgasströme 3 und 8 verschiedene Bereiche im Prozessbereich 5 abdecken und eine verbesserte Reinigungswirkung oder Abblaswirkung erzielt werden. Außerdem wird der innere Sekundärgasstrom 4 zwischen den beiden Primärgasströmen 3 und 8 sehr gut geführt und kann somit eine praktisch verlustfreie oder praktisch nicht abgeschwächte Konditionierung im Prozessbereich 5 bewirken.In this embodiment, the two primary gas streams 3 and 8 can cover different areas in the process area 5 and an improved cleaning effect or blow-off effect can be achieved. In addition, the inner secondary gas flow 4 between the two primary gas streams 3 and 8 is very well managed and can thus effect a virtually lossless or virtually unattenuated conditioning in the process area 5.

Der Primärteilstromkanal 27 kann in einer nicht dargestellten Ausführungsform um ein Drehgelenk oder Drehlager schwenkbar sein. Die Schwenkachse ist dabei im Bereich der Primäraustrittsöffnung 13 angesiedelt. Dadurch ist es möglich, den Primärgasstrom 3 in einem Raumwinkelbereich zu schwenken und dadurch diesen Bereich mit dem Primärgasstrom 3 zu beströmen. Somit kann ein größerer Bereich im Prozessbereich 5 mit der Konditionierwirkung des Primärgasstromes 3, beispielsweise zum Abblasen von Staub, beaufschlagt werden. Der Sekundärgasstrom 4 wird dabei durch die Richtstrahlcharakteristik des Primärgasstromes 3 bei der Schwenkbewegung mitgeführt.The primary part flow channel 27 may be pivotable in a non-illustrated embodiment about a rotary joint or pivot bearing. The pivot axis is located in the region of the primary outlet opening 13. This makes it possible to pivot the primary gas stream 3 in a solid angle range and thereby flow around this area with the primary gas stream 3. Thus, a larger area in the process area 5 with the conditioning effect of the primary gas stream 3, for example, for blowing off dust, be charged. The secondary gas stream 4 is carried along by the directional beam characteristic of the primary gas stream 3 during the pivoting movement.

Auch in der Ausführungsform gemäß FIG 3 und 4 wäre es auch möglich, einen Primärteilstromkanal wie in FIG 2 als Verlängerung des Primärströmungskanals 15 vorzusehen. In dieser Ausführungsform könnte der Primärteilstromkanal auch in einem Kugelgelenk oder dergleichen in zwei Winkelrichtungen, also sphärisch in einem Raumwinkelbereich geschwenkt werden.Also in the embodiment according to 3 and 4 it would also be possible to use a primary partial flow channel as in FIG. 2 provide as an extension of the primary flow channel 15. In this embodiment, the Primärteilstromkanal could also be pivoted in a ball joint or the like in two angular directions, that is spherical in a solid angle range.

Das für das Konditioniergas 6 verwendete Gas ist in allen Ausführungsformen in der Regel Luft oder ein der Zusammensetzung von Luft sehr ähnliches Gas, wobei üblicherweise Luft aus einem Außenraum oder der Erdatmosphäre entnommen, gereinigt und nach Beaufschlagung mit der Konditioniergröße (Konditionierung) in den Zuleitkanal 7 geleitet wird.The gas used for the conditioning gas 6 is in all embodiments usually air or a composition of air very similar gas, usually air from an outdoor space or the earth's atmosphere taken, cleaned and after exposure to the conditioning size (conditioning) in the supply channel. 7 is directed.

Die mit dem Konditioniergasstrom 2 gemäß der Erfindung, insbesondere in den dargestellten Ausführungsformen, ermöglichte Konditionierung eines Prozessbereiches 5 oder einer prozessrelevanten Zone wird abhängig von dem in diesem Prozessbereich 5 ablaufenden Prozess, insbesondere den dort durchlaufenden Produkten oder einzustellenden Prozessbedingungen (Prozesskonditionen), gewählt und kann prinzipiell jede mit einem Gasstrom erreichbare Konditionierung eines Prozesses oder eines Prozessbereiches sein.The conditioning of a process area 5 or a process-relevant zone made possible with the conditioning gas stream 2 according to the invention, in particular in the illustrated embodiments, is selected and can be dependent on the process taking place in this process area 5, in particular the products or process conditions (process conditions) to be passed there in principle, be any achievable with a gas flow conditioning a process or a process area.
