Abstract

An assembly introduces a gas into a liquid as part of a treatment process. The assembly comprises a horizontal gas pipe with tangential slits (8) discharging into a surrounding pipe (1) through which a flow of water (9) is maintained. The water (3) descends at an angle under gravity, entering one side of the outer pipe (1) to drive an advancing spiral motion (9) which also ingests a continuing supply of oxygen.

Description

Die Erfindung betrifft eine Vorrichtung zum Eintrag von Luft oder anderem Gas in fließende flüssige Medien zu deren Belüftung und/oder zu deren Bega­ sung, insbesondere zur Belebung von Gewässern und zur Herbeiführung chemischer sowie biochemischer Reaktionen.The invention relates to a device for entry from air or other gas into flowing liquid Media for their ventilation and / or for their Bega solution, in particular for the revitalization of water and to bring about chemical and biochemical Reactions.

Bekannt ist es, flüssige Medien insbesondere Abwäs­ ser mittels davon umspülter starrer oder rotierender Düsen durch einblasen komprimierter Luft zu begasen oder zu belüften.It is known to wash off liquid media in particular water by means of rigid or rotating water Gassing nozzles by blowing compressed air or to ventilate.

Nachteilig ist daran, daß bei Anwendung rotierender Düsen, ein erheblicher gerätetechnischer Aufwand für Kompressoranlagen, Rührwerke und Baukonstruktionen erforderlich ist.The disadvantage is that when using rotating Nozzles, a considerable expenditure on equipment Compressor systems, agitators and building structures is required.

Bei der Anwendung von starren, etwa gleichmäßig am Grund eines Behältnisses oder eines Gewässers ange­ ordneten feststehenden Düsen verschmutzen oder ver­ stopfen diese infolge von Sedimentation oft sehr schnell und beeinträchtigen damit die Funktionsfä­ higkeit der Anlage. When using rigid, about evenly on Due to a container or a body of water ordered fixed nozzles dirty or ver They often stuff very much as a result of sedimentation quickly and thus impair the functionality ability of the system.  

Bekannt sind weiterhin Ejektor oder Strahldüsenbe­ lüfter die mit Hochdruckpumpen betrieben werden. Nachteilig ist daran, daß, falls das Treibmedium zu sehr mit Feststoffen angereichert ist oder sonst eine hohe Viskosität aufweist, diese besondere Treibflüssigkeiten erfordern.Ejectors or jet nozzles are also known fans that are operated with high pressure pumps. The disadvantage of this is that if the propellant is too is very enriched with solids or otherwise has a high viscosity, this particular Require propellants.

Nachteilig ist den bekannten Ausführungen gemeinsam, daß sie bei einen immensen gerätetechnischen Aufwand auch energie- und wartungsaufwendig sind.A disadvantage of the known designs is common, that they require an immense amount of equipment are also energy and maintenance consuming.

Bekannt ist es auch, eine bekannte Strahlpumpe in ein fließendes Gewässer so einzusetzen, daß das Fließwasser Treibmittel ist und dabei Luft über eine Leitung angesaugt und sich sodann Fließwasser und Luft vermischen (DE 43 12 971 A1).It is also known to have a known jet pump in to use flowing water so that the Running water is a blowing agent and air is flowing through it Line sucked in and then running water and Mix air (DE 43 12 971 A1).

Nachteilig daran ist die geringe Effektivität von bekannten Strahlpumpen für die Belüftung von Gewäs­ sern.The disadvantage of this is the low effectiveness of known jet pumps for the aeration of water ser.

Bekannt ist weiterhin eine Strahlpumpe zur Förderung von Schüttgut die sich sowohl mit Druckluft als auch mit Druckwasser als Treibmittel sowie mit beiden gemeinsam betreiben läßt. A jet pump for conveying is also known of bulk material that can be both compressed air and with pressurized water as a blowing agent and with both operated together.  

Diese Strahlpumpe erfordert hohe Arbeitsdrücke für deren Betrieb. Sie ist deshalb nicht für die selbst­ tätige Begasung von Gewässern geeignet.This jet pump requires high working pressures for their operation. It is therefore not for them active fumigation of water suitable.

Problem der Erfindung ist es eine Vorrichtung zur Belüftung und/oder zur Begasung von fließenden flüs­ sigen Medien, zu schaffen, die mit geringem geräte­ technischem Aufwand realisierbar ist und die zu ihrem Betrieb einen geringen Energieaufwand erfor­ dert, wobei letzteres durch Nutzung der zum Behan­ deln der Flüssigkeiten in dieser bereits immanenten Stömungsenergie, die als kinetische Energie im flie­ ßendem flüssigem Medium vorhanden ist weiter nutztbar gemacht wird. Die Vorrichtung soll auch robust, zuverlässig und wartungsarm sein und damit einen größtmöglichem ökologischen Nutzens bei ge­ ringstem ökonomischen Aufwand aufweisen.Problem of the invention is a device for Ventilation and / or for the gassing of flowing rivers media, to create with little equipment technical effort is realizable and that too their operation requires little energy changed, the latter by using the to treat of the liquids in this already immanent Flow energy, which flows as kinetic energy in the ßenden liquid medium is present is made usable. The device should also be robust, reliable and low-maintenance and thus the greatest possible ecological benefit at ge show least economic effort.

Erfindungsgemäß wird das Problem wie mit den Patent­ ansprüchen angegeben gelöst.According to the invention, the problem is as with the patent claims stated solved.

Die Vorzüge der Erfindung bestehen darin, daß sich damit chemische und biochemische Reaktionen durch Eintrag von Gas in Flüssigkeiten mit einem minimalem gerätetechnischen und ernergetischen Aufwand reali­ sieren lassen.The advantages of the invention are that chemical and biochemical reactions Entry of gas into liquids with a minimal equipment and energy expenditure reali let sieren.

Nachstehend wird die Erfindung an einem Ausführungs­ beispiel näher erläutert.In the following the invention is carried out on an embodiment example explained in more detail.

Fig. 4 die Düsengestaltung im Detail schematisch dargestellt. Fig. 4 schematically shows the nozzle design in detail.

Die Vorrichtung ist für die Belüftung von geklärtem fließendem Abwasser (flüssiges Medium 9) konzi­ piert.The device is designed for the ventilation of clarified flowing waste water (liquid medium 9 ).

Sie besteht aus dem, das Gehäuse derselben bilden­ den, in Strömungsrichtung des Abwassers (flüssiges Medium 9) einseitig offenem Pumpenrohr 1. Dies ist an einem seiner Enden in Strömungsrichtung des Abwassers (flüssiges Medium 9) offen und an seinem anderen Ende, entgegen der Srömungsrichtung des Abwassers (flüssiges Medium 9) mittels Pumpenrohr­ verschluß 2 geschlossen. It consists of the housing of the pump tube 1, which is open on one side in the flow direction of the waste water (liquid medium 9 ). This is open at one of its ends in the flow direction of the waste water (liquid medium 9 ) and at its other end, against the flow direction of the waste water (liquid medium 9 ) by means of a pump tube 2 .

In diesem Pumpenrohr 1 ist zentrisch zu demselben das Saugrohr 6, für die Zuführung von Luft (gasför­ miges Medium 10) zur Belüftung des Abwassers (flüs­ siges Medium 9), durch den Pumpenrohrverschluß 2 hindurchreichend, angeordnet und an diesem dichtend befestigt. Das in Strömungsrichtung befindliche Saugrohrende 7 ist geschlossen, das andere, durch den Pumpenrohrverschluß hindurchreichende Ende des Saugrohres ist offen. Nahe dem Saugrohrende 7 sind am Umfang desselben mehrere schlitzförmige Öffnungen 8 gleichmäßig beabstandet und winklig im Winkel von etwa 45° quer zur Längsachse des Saug­ rohres 6 so angeordnet, daß das im Pumpenrohr 1 strömende Abwasser (flüssiges Medium 9) diese schlitzförmigen Öffnungen 8 quert. Diese schlitzför­ migen Öffnungen 8 sind dabei so gestaltet, daß deren Abrißkante für das darüber hinweg strömende Abwasser (flüssiges Medium 9) spitzwinklig ausgebildet sind.In this pump tube 1 , the suction tube 6 is centered to the same, for the supply of air (gasför shaped medium 10 ) for aeration of the waste water (liquid medium 9 ), reaching through the pump tube closure 2 , arranged and fastened sealingly thereon. The suction pipe end 7 located in the flow direction is closed, the other end of the suction pipe, which extends through the pump pipe closure, is open. Near the end of the suction pipe 7 , several slit-shaped openings 8 are evenly spaced around the circumference thereof and arranged at an angle of approximately 45 ° transversely to the longitudinal axis of the suction pipe 6 so that the wastewater flowing in the pump pipe 1 (liquid medium 9 ) crosses these slit-shaped openings 8 . This slit-shaped openings 8 are designed so that their tear-off edge for the overflowing waste water (liquid medium 9 ) are formed at an acute angle.

Seitlich des Pumpenrohres 1 und an diesem dichtend befestigt und mit einem flachen etwa rechteckigem lichten Querschnitt in dieses spitzwinklig in Strö­ mungsrichtung über die Einströmöffnung 4 einmündend, ist das Treibrohr 3 so angeordnet, daß eine Breit­ seite des lichten Querschnittes desselben die innere Peripherie des Pumpenrohres 1 tangiert und die ande­ re Breitseite des lichten Querschnittes mit der äußeren Peripherie des Saugrohres 6 tangential fluchtet. Die Länge der Breitseiten der Einström­ öffnung 4 ist der Quotient aus der lichten Quer­ schnittsfläche der Einströmöffnung 4, geteilt durch das Maß der Höhe des Ringspaltes 5.Laterally of the pump tube 1 and sealingly attached to it and with a flat approximately rectangular clear cross section opening into this at an acute angle in the flow direction via the inflow opening 4 , the drive tube 3 is arranged such that a broad side of the clear cross section of the same the inner periphery of the pump tube 1 tangent and the other right broad side of the clear cross section is tangentially aligned with the outer periphery of the suction tube 6 . The length of the broad sides of the inflow opening 4 is the ratio of the internal cross-sectional area of the inlet opening 4, divided by the measure of the height of the annular gap. 5

In Funktion der erfindungsgemäßen Vorrichtung ist das zu belüftende Abwasser (flüssiges Medium 9) die Treibflüssigkeit. Es strömt durch das Treibrohr 3 und die Einströmöffnung 4 spitzwinklig in das Pum­ penrohr 1 ein und trifft dabei auf den Ringspalt 5 wobei ein Strömungsdruckabfall entsteht und Pralldruck vermieden wird. Infolge der Gestaltung von Pumpenrohr 1, Treibrohr 3 und Saugrohr 6 sowie der erfindungsgemäßen Anordnung und Bemessung der­ selben erhält der Strom des Abwassers (flüssiges Medium 9) im Ringspalt 5 einen wendelartigen Drall, und quert dabei die an Umfang des Saugrohres 6 be­ findlichen schlitzartigen Öffnungen 8 etwa recht­ winklig.As a function of the device according to the invention, the wastewater to be aerated (liquid medium 9 ) is the propellant. It flows through the drive tube 3 and the inflow opening 4 at an acute angle into the pump tube 1 and strikes the annular gap 5 whereby a drop in flow pressure occurs and impact pressure is avoided. As a result of the design of the pump tube 1 , drive tube 3 and suction tube 6 and the arrangement and dimensioning of the same according to the invention, the flow of waste water (liquid medium 9 ) in the annular gap 5 receives a helical swirl, and thereby crosses the slit-like openings on the circumference of the suction tube 6 8 roughly angled.

An den Abrißkanten der schlitzförmigen Öffnungen 8 entsteht dabei ein Unterdruck infolge dessen Luft (gasförmiges Medium 10) aus den Saugrohr 6 angesaugt wird und sich diese mit dem Abwasser (Medium 9) in sehr feiner Vertei­ lung vermischt. Durch die Querschnittserweiterung unmittelbar an dem Saugrohrende 7 entstehen hier Turbulenzen die eine weitere homogene Vermischung von Lüft (gasförmiges Medium 10) und Abwasser (flüssiges Mediun 9) zu einem reaktiven Flüssig­ keits-Gas-Gemisch intensivieren und damit zu einer optimalen Oberflächenerweiterung des Abwassers (flüssiges Medium 9) führt.At the tear-off edges of the slot-shaped openings 8 there is a negative pressure as a result of which air (gaseous medium 10 ) is sucked out of the suction pipe 6 and this mixes with the waste water (medium 9 ) in a very fine distribution. Due to the cross-sectional expansion directly at the suction pipe end 7 , turbulence arises which intensify a further homogeneous mixing of vent (gaseous medium 10 ) and waste water (liquid medium 9 ) to form a reactive liquid-gas mixture and thus to an optimal surface expansion of the waste water (liquid Medium 9 ) leads.
