Description

Gefällemischrinne mit zickzackförmiger Flüssigkeitsführung zur Behandlung von schäumenden Abwässern Die Erfindung betrifft eine Gefällemischrinne mit zickzackförmiger Flüssigkeitsführung zur Behandlung von schäumen dem Abwasser, insbesondere von Schlachthofabwass,er mit desinfizierenden Flüssigkeiten, und bezweckt eine gründliche und trotzdem schaumfreie Vermischung der Flüssigkeitsbestandteile. Dies wird erfindungsgemäß dadurch erreicht, daß die den zickzackförmigen Flüssigkeitsweg bildenden Ablenker an den von der Flüssigkeit in der Fallrichtung beaufschlagten Flächen konkav ausgebildet und die beaufschlagten Ecken abgestumpft sind.Gradient mixing channel with zigzag liquid flow for treatment of foaming sewage The invention relates to a sloping mixing channel with a zigzag Liquid management for the treatment of foaming wastewater, in particular slaughterhouse wastewater, he with disinfecting liquids, and aims to ensure a thorough and nonetheless foam-free Mixing of the liquid components. According to the invention, this is achieved by that the deflectors forming the zigzag fluid path are attached to the fluid in the direction of fall acted upon surfaces formed concave and the acted upon Corners are blunted.

Es sind bereits Vorrichtungen zum Mischen von Flüssigkeiten bekannt, die aus ganz schmalen, wellenförmigen und auch zickzackförmigen Kanälen bestehen, durch welche die Mischungen vorzugsweise unter Druck hindurdhgeführt werden. Diese bekannten Kanalformen -erwiesen sich aber beim Versuch, schäumende Abwässer im natürlichen Gefälle zu behandeln, als unbrauchbar, da eine derartig starke Schaumbildung auftrat, daß ein Teil der Flüssigkeit der Durchmischunglentzogen in Schaumform über den Ablenkern abtrieb. Devices for mixing liquids are already known, which consist of very narrow, wave-shaped and also zigzag-shaped channels, through which the mixtures are preferably passed under pressure. These well-known canal shapes -but when trying to use foaming wastewater in natural To treat the slope as unusable, since such a strong foam formation occurred, that part of the liquid is withdrawn from mixing in foam form over the deflectors output.

In der Zeichnung ist eine Gefällemischrinne gemäß der Erfindung dargestellt. und zwar zeigt Fig. I eine Seitenansicht. In the drawing, a gradient mixing channel according to the invention is shown. namely Fig. I shows a side view.

Fig. 2 einen Grundriß und Fig. 3 einen Querschnitt durch die Rinne nach Linie III-III von Fig. 2. Fig. 2 is a plan view and Fig. 3 is a cross section through the channel according to line III-III of FIG. 2.

Die Mischrinne besteht aus einem schräg in der gewünschten Fallrichtung gelagerten Rinnenkasten a, z.B. aus Eisenbledh, der oben offen ist und an dessen höher gelegener Stirnseite ein Zul,eitungsstutzenb und an der tiefer gelegenen Stirnseite ein Ableitungsstutzen c sitzt. Von den beiden gegenüberliegenden Längsseiten der Rinne ragen in diese pnsmatische Abienklörperd von etwa dreieckigem Querschnitt derart gegeneinan der versetzt hinein. daß sie zwischen sich und im Rinnenboden einen zickzackförmigen, schmalen Flüssigkeitsweg e frei lassen. Die Ablenker können aus einem massiven Stück bzw. Beton bestehen, aber auch hohl ausgebildet sein. Die von der Flüssigkeit in der Fallrichtung beaufschlagten Flächen / der Ablenker sind konkav ausgebildet und die von der Flüssigkeitsströmung beaufschlagten Ecken g der Zickzackbahn abgestumpft, d. h. die Ablenkerd sind mit Abstand voneinander auf die Seiteuflächen der Rinne aufgesetzt, während ihre freien Wanten spitz und ihre nichtbeaufschlagten Flächen !eben ausgebildet sind. Man erreicht durch diese besondere Gestaltung und Anordnung der Ablenker, daß an den für die Mischung besonders rvirksamen Umienkstdlen keine störende Schaum bildung auftritt. die sonst zur Folge hat, daß die Flüssigkeit in Sc;haumform über die Ablenker hinweg fließt. The mixing trough consists of an inclined in the desired direction of fall stored gutter box a, e.g. made of Eisenbledh, which is open at the top and attached to it The higher end face has a supply pipe, and on the lower end face a discharge nozzle c is seated. From the two opposite long sides of the Grooves protrude into this pneumatic Abienklbodyd of approximately triangular cross-section so against one another the staggered into it. that they are between themselves and in the bottom of the gutter leave a zigzag-shaped, narrow fluid path e free. The distractors can consist of a solid piece or concrete, but can also be made hollow. the surfaces / deflectors acted upon by the liquid in the direction of fall concave and the corners acted upon by the flow of liquid g of Zigzag path truncated, d. H. the deflectors are spaced from each other on the On the side surfaces of the channel, while its free shrouds are pointed and theirs are not acted upon Surfaces! Are flat. One achieves through this special design and Arrange the deflectors in the places that are particularly effective for the mixture no disruptive foam formation occurs. which otherwise has the consequence that the liquid flows in the form of a foam over the deflectors.

Die Mischrinne eignet sich beispielslveise für die Behandlung von Schlachthofabwässern mit desinfizierenden Zusätzen, wie aktives Chlor entha]tende Flüssigkeiten. The mixing channel is suitable, for example, for the treatment of Slaughterhouse wastewater with disinfecting additives, such as those containing active chlorine Liquids.
