Zum Abscheiden von Staub aus diesen enthaltende Luft sind Venturiwäscher bekannt, die vor dem konvergierenden Teil eine zentral angeordnete, zur engsten Stelle des Venturirohres wirkende, mit Luft und Wasser betriebene Sprühdose aufweisen. Hiermit ist jedoch eine homogene Verteilung des Wassers in der zu reinigenden Luft nicht möglich. Dieser Nachteil wird vermieden, wenn erfindungsgemäß die Sprühdüse auch entgegen der engsten Stelle des Venturirohres wirkend ausgebildet ist und senkrecht vor ihrer Öffnung eine Prallplatte aufweist.For separating dust from these containing air Venturi scrubbers are known, which before the converging Part of a centrally arranged, acting towards the narrowest point of the venturi tube, with air and water powered spray can. However, this ensures a homogeneous distribution of the water in the air to be cleaned is not possible. This disadvantage is avoided when according to the invention Spray nozzle is also designed to act against the narrowest point of the Venturi tube and is perpendicular has a baffle plate in front of its opening.
Es ist zwar auch bekannt, vor den konvergierenden Teil des Venturirohres mittels einer rotierenden Scheibe einen Wasserschleier quer zur Rohrachse zu legen. Jedoch erleidet dabei die axial geleitete Primärströmung, indem sie der senkrechten sekundären Strömung begegnet, eine nachteilige turbulente Bewegung mit Wirbelverlauf.Although it is also known, in front of the converging part of the venturi by means of a rotating Washer to lay a veil of water across the pipe axis. However, the axially directed primary flow suffers, by encountering the perpendicular secondary flow, a detrimental turbulent motion with vortex course.
Die erfindungsgemäße Vorrichtung ist dagegen so ausgebildet, daß die Sprühdüse auch entgegen der engsten Stelle des Venturirohres wirkend ausgebildet ist und senkrecht vor ihrer Öffnung eine Prallplatte aufweist.The device according to the invention, however, is designed so that the spray nozzle also against the The narrowest point of the Venturi tube is designed to act and a baffle plate perpendicular to its opening having.
Die im konvergierenden Teil strömende Luft wird also im axialen Bereich in bekannter Weise und im peripheren Teil angefeuchtet.The air flowing in the converging part is therefore in a known manner in the axial area and in the peripheral part moistened.
An Hand der Zeichnung wird die Vorrichtung näher beschrieben.The device is described in more detail with reference to the drawing.
F i g. 1 ist ein Längsschnitt durch das Venturirohr;F i g. 1 is a longitudinal section through the venturi;
F i g. 2 ist eine Stirnansicht der von der rechten Seite der Fig. 1 aus gesehenen Vorrichtung;F i g. Figure 2 is an end view of the device as seen from the right side of Figure 1;
Fig. 3 ist ein Längsschnitt in vergrößertem Maßstab durch die Zerstäubungsdüse.Figure 3 is a longitudinal section, on an enlarged scale, of the atomizing nozzle.
Das Venturirohr la, Ib, lc ist in einem zylindrischen Mantel 2 angeordnet. In der Eingangsöffnung des Kegelstumpfes la ist in der Längsachse eine Sprühdüse 3 vorgesehen, die von drei Radialarmen 4 gehalten ist. An der Sprühdüse 3 sind eine Druckluft- und eine Wasserleitung 5 und 6 angeschlossen. The Venturi tube 1 a, 1 b , 1 c is arranged in a cylindrical jacket 2. In the inlet opening of the truncated cone la, a spray nozzle 3 is provided in the longitudinal axis, which is held by three radial arms 4. A compressed air line and a water line 5 and 6 are connected to the spray nozzle 3.
Die Sprühdüse 3 erzeugt innerhalb des Venturirohres 1 einen Unterdruck, durch den die staubhaltige Umgebungsluft eingesaugt wird, einen Kegel aus zerstäubtem Wasser / in Richtung des Teiles 1 c des Venturirohres, der zentrisch zur Achse des Venturirohres verläuft und einen Wasserschleier J1 in einer Querebene vor der Eingangsöffnung des Mantels 2.The spray nozzle 3 generates a negative pressure inside the venturi tube 1 through which the dusty ambient air is sucked in, a cone of atomized water / in the direction of part 1c of the venturi tube, which runs centrally to the axis of the venturi tube and a water veil J 1 in a transverse plane in front the inlet opening of the shell 2.
Die schwebenden Teilchen werden also in dem Wasserkegel/ und dem WasserschleierZ1 innig mit Wasser gemischt.The floating particles are therefore intimately mixed with water in the water cone / and the water veil Z 1.
Gemäß F i g. 3 besteht die Sprühdüse 3 aus drei VenturiwäscherAccording to FIG. 3, the spray nozzle 3 consists of three venturi washers

Die Druckluft und das Wasser werden einerseits in den vorderen Teil a geleitet, um zunächst einen axialen Strahl zu bilden, der durch die Prallscheibe 9 radial abgelenkt wird und einen quergerichteten Schleier J1 bildet. Aus dem hinteren Teil 3 b tritt das aus Druckluft und Wasser gebildete Gemisch unter der Gestalt eines axial gerichteten Kegels / aus.and water are connected to the spray nozzle by standardized connections 5 a and 6 a. The compressed air and the water are fed into the front part a , on the one hand, in order to initially form an axial jet which is deflected radially by the baffle plate 9 and forms a transversely directed veil J 1 . The mixture formed from compressed air and water emerges from the rear part 3 b under the shape of an axially directed cone /.
