Description

Einlaufvorrichtung für Klärbecken Bei den bekannten, für die Aufbereitung von schwebestoffhaltigen Wässern erstellten Klärbecken für horizontalen Durchfluß in Rechteck- und Rundform ist der Kläreffekt eines Beckens bestimmter Größe abhängig von der Wassergeschwindigkeit, die theoretisch in der Strömungsrichtung über den ganzen Beckenquerschnitt konstant sein soll.Inlet device for clarifiers In the known, for processing Clarification basins for horizontal flow created from water containing suspended matter The clarifying effect of a basin of a certain size depends on the rectangular and round shape on the water speed, which theoretically is in the direction of flow over the should be constant throughout the pelvic cross-section.

Verteilerschächte und Verteilerkammern mit Wasserumlenkeinrichtungen sowie diesen nachgeschaltete Einlaufrohre mit Verteilerplatten und Prallkörper ermöglichen bereits unter Ausnutzung des entstehenden Druckgefälles zum Klärbecken eine weitgehende gleichmäßige Beaufschlagung der Beckenklärkammern mit aufzubereitendem Wasser und eine Verminderung der am Auslauf frei werdenden Strömungsenergie. Manifolds and distribution chambers with water deflection devices as well as these downstream inlet pipes with distributor plates and baffle bodies an extensive one, even when the pressure gradient to the clarifier is used uniform application of water to be treated to the basin clarification chambers and a reduction in the flow energy released at the outlet.

Die bekannten Einrichtungen zeigen indessen den nachteil, daß der Überstau des Wassers vor der Klärbeckeneinlaufwand abhängig ist von der in einer bestimmten Zeiteinheit zufließenden Wassermenge und demzufolge gerade bei erhöhtem Zufluß der Kläreffekt herabgesetzt wird. The known devices, however, show the disadvantage that the The overflow of the water in front of the clarifier inlet wall is dependent on the in one certain time unit inflowing amount of water and, consequently, precisely when it is increased Inflow of the clarifying effect is reduced.

Einbauten in Rohwasser-Vorkammern zur Wasserumlenkung und zur Steuerung des Durchflusses sind besonders bei mit Fett- und Feststoffen beladenen Wässern nachteilig, da diese Wässer in bekannten Strömungszonen ablagern und weitere Querschnittsverengungen ergeben. welche die erwähnten Mängel zeigen. Fittings in raw water pre-chambers for water diversion and control of the flow are particularly in the case of water loaded with fat and solids disadvantageous because these waters are deposited in known flow zones and further cross-sectional constrictions result. which show the shortcomings mentioned.

Klärbeckenseitig an die Einlaufrohre angesetzte einstufige Prallkörper und Verteilerflächen mit und ohne Bohrungen lenken je nach Ausbildung derselben den Wasserzufluß um. doch erreichen sie selbst bei günstiger Anordnung nur Teilerfolge, da sich - bedingt durch größeren Wasserdurchsatz - die Geschwindigkeit und Turbulenz am Einlauf des Klärbeckens in Nähe der Klärzone erhöht. Single-stage baffles attached to the inlet pipes on the clarifier side and distribution surfaces with and without bores steer depending on the design of the same the water flow around. but even with a favorable arrangement they only achieve partial successes, because - due to the greater water throughput - the speed and turbulence increased at the inlet of the clarifier near the clarification zone.

Hier schafft die Erfindung Abhilfe. Sie besteht darin daß die einzelnen Prallkörper in mindestens zwei hintereinanderliegende Prallplatten unterteilt sind. The invention provides a remedy here. It consists in that the individual Impact bodies are divided into at least two impact plates lying one behind the other.

Dadurch wird eine bessere Verteilung des Wassers erzielt. Diese bessere Verteilung wird dadurch gewährleistet. daß der Hauptstrom durch die Aufteilung mehrerer hintereinander angeordneter Verteilerströme in Einzelströme aufgeteilt wird. This results in a better distribution of the water. This better one This ensures distribution. that the main stream by dividing several distribution streams arranged one behind the other is divided into individual streams.

Ein weiteres Erfindungsmerkmal besteht darin, daß die Oberkante der einlaufseitigen Beckenwand als mit einer Stauschwelle versehener Überlauf ausgebildet ist. Another feature of the invention is that the upper edge of the The basin wall on the inlet side is designed as an overflow provided with a damming wave is.

Bei dem erfindungsgemäßen Einlauf ist trotz veränderlichen Rohwasserzufiusses infolge eines fast in gleichbleibender Höhe gehaltenen Vorstauwasserspiegels die Strömungsgeschwindigkeit in den Verteileröffnungen der Klärbeckenwand unveränderlich. In the case of the inlet according to the invention, despite the variable raw water inflow as a result of an almost in the backwater level maintained at a constant height Flow velocity in the distributor openings of the clarifier wall unchangeable.

Die Vorkammer eines Klärbeckens kann nach Baugröße und Bauform für den Durchsatz einer bestimmten Wassermenge bemessen werden mit dem Vorteil, auch ohne besondere Einbauten eine in der Zeiteinheit gleichbleibende Wassergeschwindigkeit zu erreichen, welche über der Sinkgeschwindigkeit der absetzbaren Stoffe des Rohwassers liegt. The pre-chamber of a clarifier can be for The throughput of a certain amount of water can be measured with the advantage, too without special installations, a constant water speed in the unit of time to achieve which is above the sinking speed of the settling substances in the raw water lies.

Ein Ausführungsbeispiel der Erfindung ist in Abb. 1 im Schnitt und in Abb. 2 in der Draufsicht dargestellt. Die Beckenwand 5 trennt eine nach oben offene Rohwasservorkammer vom eigentlichen Klärbecken. Klärbeckenseitig sind Verteileröffnungen vorhanden oder Rohre 1 eingebaut, denen sich Energievernichter in Form von mindestens zwei hintereinandergeschalteten Prallplatten 2 und 3 mit zentraler Öffnung 4 vorlagern. An embodiment of the invention is shown in Fig. 1 in section and shown in Fig. 2 in plan view. The pool wall 5 separates one upwards open raw water antechamber from the actual clarifier. There are distributor openings on the clarifier side present or installed pipes 1, which are energy destroyers in the form of at least place two baffle plates 2 and 3 connected in series with a central opening 4 in front of them.

Die Oberkante der Beckenwand 5 ist mit einem Überlauf 6 und klärbeckenseitig mit einer Stauschwelle 7 versehen. Der Überlauf 6 und die Stauschwelle 7 liegen in bestimmter Höhe über dem Klärbeckenwasserspiegel. Durch die Stauschwelle 7 wird beim Wasserübertritt über den Überlauf 6 zum Klärbecken zwangläufig eine Wirbelbildung erzeugt und so in einer zunächst für den Kläreffekt untergeordneten Zone stetig Strömungsenergie vernichtet. The upper edge of the basin wall 5 has an overflow 6 and is on the clarifier side provided with a stowage shaft 7. The overflow 6 and the flood barrier 7 are located at a certain height above the clarifier water level. Through the congestion wave 7 is When the water passes over the overflow 6 to the clarifier, eddy formation is inevitable generated and so in a first subordinate for the clarifying effect Zone steadily destroyed by flow energy.
