Abstract

The cylindrical vessel of the overpressure eddy reactor, to clean sewage soiled by organic matter, has an upper outlet connection for the activated mixt. and the foam disperser,. At the lower end there is a connection to empty the cylinder and allow a closed circuit to be formed for the mixture. The entry inlet connection at the lower end of the cylinder, gives a tangential inflow, which can be connected to the lower outlet to form the closed circuit and also give the insertion of the special eddy jet into the cylinder vessel. The eddy jet is pref. in two tubes, within each other. The outer tube with the compressed air connection, is welded to the jet head. The inner tube, with the connection for the sewage and return foam mixture, opens into the mixing zone in the jet head where the bacteria agglomerates and air bubbles are reduced. The mixt. is forced from the mixing zone by pressure pumps and compressed air at a tangent into the cylindrical vessel, which keeps the matter rotating. The function of the reactor is based on an overpressure. ADVANTAGE - The appts. gives a high O2 delivery and breathing activity, with min. energy requirements and space for the assembly, for universal application in relation to reaction and vols.

Description

Die Erfindung betrifft einen Überdruck-Wirbel-Reaktor mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an overpressure vortex reactor with the Features of the preamble of claim 1.

Der Erfindung liegen folgende Aufgaben zugrunde.The invention is based on the following objects.

  • - hoher Sauerstoffeintrag und Veratmungsaktivität,- high oxygen input and breathing activity,
  • - minimale Energiezufuhr,- minimal energy input,
  • - geringer Platzbedarf,- little need for space,
  • - universeller Einsatz in bezug auf Reaktion bzw. Bauvolumen.- Universal use in terms of reaction or construction volume.

Die Aufgabe wird nach heutigem Stand der Technik durch aufwendige Konstruktion gelöst. Aus technischen und verfahrenstechnischen Gründen müssen das Reaktions- und Bauvolumen klein gehalten werden. Dies beinhaltet hohe Investitionen und Betriebskosten. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge­ stellt und wird nachfolgend näher erläutert:According to the current state of the art, the task is complicated Construction solved. From technical and procedural For reasons the reaction and construction volume must be kept small will. This includes high investments and operating costs. An embodiment of the invention is shown in the drawing provides and is explained in more detail below:
