Abstract

Propulsion and agglomeration section for wet dust suppressor, e.g. for mines, comprises a water ring nozzle surrounding the propellant jet of pressurised air at its exit. In an example, the propellant jet is discharged with max. efficiency by supplying air at a given point to the propellant jet nozzle, and is moistened by high water press, which is supplied at, through the ring nozzle assembly, so as to obtain a high level of agglomeration even in the zone of max. expansion. In this way the trailing effect of the propellant jet is affected only slightly while max. confrontation is forced between the rapid-flowing water-air mixt. and the noxious materials e.g. dust.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

'Treibstrahl- und Agglomerationsstrecke, vorzugsweise für Naßents tauber.'' Propulsion jet and agglomeration section, preferably for Naßents deaf.

Es ist bekannt, Naßentstauber, die sporadisch, kurzzeitig Einsatz finden, z. B. für untertägigen Bergbau, im Bereich von intermitierend arbeitenden Bergebrechanlagen mit Druckluft-Treibstrahl Unterdruckerzeugung zu betreiben.It is known to use wet dust extractors sporadically, briefly find, e.g. B. for underground mining, in the area of intermittent working To operate mountain crushing systems with compressed air propulsion jet generation of negative pressure.

Das zugeführte Wasser zur Agglomeration der Stäube wird entweder im Ansaugstrom zugegeben oder/aber zweckdienlicher in den expandierenden Druckluftstrahl eing eblasen.The water supplied for agglomeration of the dusts is either in Suction flow added or / but more expedient in the expanding compressed air jet blow in.

Die Wasserzugabe im expandierenden Druckluftstrahl hat den erheblichen Nachteil, daß die Schleppstrahlwirkung des expandierenden Druckluftstrahls stark gemindert wird.The addition of water in the expanding compressed air jet has the significant Disadvantage that the drag jet effect of the expanding compressed air jet is strong is reduced.

Die Zuführung des Wassers in den Rohgasstrom bewirkt eine nicht intensive Kontaktierung auf der Sekundär-Rohgasseite, und somit ist die gewünschte Agglomeration nicht optimiert.The feeding of the water into the raw gas flow does not cause an intensive one Contacting on the secondary raw gas side, and thus the desired agglomeration not optimized.

Aus diesem Grunde wird erfindungsgemäß vorgeschlagen, eine Treibstrahl- und Agglomerationsstrecke entsprechend beiliegender Zeichnung zu verwenden.For this reason it is proposed according to the invention, a propulsion jet and agglomeration section according to the enclosed drawing.

In der beiliegenden Zeichnung ist dargestellt: Mit 1: die staubhaltige Sekundärluft oder das Rohgas mit 2: die Treibstrahl- und Agglomerationsdüse mit 3: die Wasserzuführung mit 4: die Treib- und Agglomerationsstrecke.The accompanying drawing shows: With 1: the dusty one Secondary air or the raw gas with 2: the propulsion jet and agglomeration nozzle with 3: the water supply with 4: the driving and agglomeration section.

Durch die Luftzuführung bei (2) in die Treibstrahldüse kann der Treibstrahl mit größter Wirkung austreten und wird durch hohen Wasserdruck, der bei (3) zugeführt wird, durch die Ringdüsenanordnung (4) angefeuchtet, so daß er bereits im höchsten eppandierenden Bereich hohe Agglomerationswerte zwangsläufig erzielt.Through the air supply at (2) into the propulsion jet nozzle, the propulsion jet with the greatest effect and is supplied by high water pressure, which is at (3) is, moistened by the ring nozzle arrangement (4), so that it is already in the highest high agglomeration values inevitably achieved.

Durch diese Maßnahme wird die Schleppstrahlwirkung des Treibstrahls nicht nennenswert beeinträchtigt und andererseits jedoch die Konfrontation von schnellfließendem Wasserluftgemisch zum Schadstoff, z. B. Staub, größtmöglich erzwungen.This measure reduces the drag jet effect of the propellant jet not significantly impaired and on the other hand, however, the confrontation of fast-flowing Water-air mixture to the pollutant, z. B. Dust, forced as much as possible.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Treibstrahl-Agglomerationsstrecke, vorzugsweise für Naßentstauber, so zu bauen, daß der Treibstrahl nicht mit in den Treibstrahl eingedüsten oder eingeimpften Flüssigkeiten konfrontiert wird, sondern eine Ringdüsenbewehrung im Bereich des Austritts des Treibstrahls mit hoher Geschwindigkeit zusätzlich vorzugsweise ebenfalls eine Schleppwirkung erzeugt, die eine innige Vermischung zwischen Treibstrahl und Flüssigkeit bewirkt.Of course, the invention is not limited to the above in detail The forms of training shown are limited, but there are numerous changes possible without however of that To deviate from the basic idea, a propulsion jet agglomeration section, preferably for wet dust extractors, to be built in such a way that the propulsion jet does not enter the Propulsion jet injected or inoculated liquids is confronted, rather a ring nozzle reinforcement in the area of the exit of the propulsion jet at high speed in addition, preferably also a drag effect which creates an intimate mixing causes between propulsion jet and liquid.
